Precise measurement of industrial handle specifications

Industrial handle is a very common machine accessories in life, widely used in chemical plants, food machinery equipment, monitors and other industries, to a certain extent, convenient for people to use industrial equipment. Mechanical equipment manufacturing industry handle material mainly divided into plastic and cast iron two kinds. Cast iron parts are divided into casting parts and CNC machining. Plastic industry handles can be divided into thermosetting plastics and thermoplastics. The following details how to identify the four kinds of processing technology industrial handle is good or bad. 1. CNC machining of cast iron: 1. Accurately measure the handle specifications. Take a look at it and see if it is processed in strict accordance with the requirements of the industry (the key is the size). 2. The screw part of the handle is different from the screw part of the screw or the die of the CNC lathe, which is the core. If the screw is rubbed out, then its accuracy and strength will not be good, and the surface will not be smooth. 3. Check whether the handling method of the handle surface is clean, without burrs, and whether the rust prevention process is up to standard. Two, forging handle in the late CNC machining solution: 1. More need to see the handle installation way, industrial handle size screw precision is not processed according to the requirements of mechanical parts. 2. Check whether sand holes exist on the surface of the gamepad. 3. Whether the handling method of the handle surface is clean, without burrs, and whether the rust prevention process is up to standard. Three, thermosetting plastic handle: Phenolic molding plastic is an important raw material for manufacturing thermosetting plastic industrial handles. It is also known as bakelite powder, plastic, or PF in English. Bakelite powder handle with insulation, wear resistance, strong strength, zero pollution, no damage to hands, corrosion resistance and other characteristics, and the surface is very bright. 1. Check whether the bakelite powder handle surface is bright and without rough edges. 2. Check whether the screws and inserts of the handle meet the level regulations, and whether the accuracy and rust prevention process meet the standards. 3. The overall accurate measurement handle is not processed according to the national standard of mechanical parts. 4. The nut and screw inserts of the handle are buried in the bakelite powder handle. A destructive test is done for the stiffness of the metal part of the bakelite handle. In general, the screws embedded in the handle should have hexagon nuts and full teeth to prevent the screws from rotating 360 degrees in the handle or falling out of the handle. Some manufacturers will continue to add a hexagon nut under the premise of hexagon nuts full teeth anchor bolts to strengthen their robustness. 4. The detection method of thermoplastic handle is the same as that of thermosetting plastic handle. The performance difference between thermosetting plastic handle and thermoplastic handle: Thermosetting plastics have high impact toughness and bright surface. With good corrosion resistance, high temperature resistance of a wide range, there will be no variation, but it is more brittle, is unable to withstand the impact of lifting objects.

The appearance of industrial handles can be divided into handles, rotating handles, etc

Industrial handle is widely used in communication, digital technology, national defense, computer equipment, electronic equipment and other fields, aluminum casing for resistance, has good maintenance performance and excellent conductivity, as an electrical conductor, it can block the current flow to a certain extent, to meet customer requirements. Industrial doorknob tensile strength is high, the application is very convenient, the relevant provisions of the automobile chassis are not the same, so the scope of application is not the same, industrial doorknob is mainly used in the field of electronic products, can reduce the probability of safety accidents. Second, it has good corrosion resistance, the relevant regulations on the working natural environment is not so strict, can be used in some chemical enterprises, can not only maintain the internal components of the switching power circuit from damage, but also take into account the requirements of customers. The key to the growing popularity of the industrial handle in the sales market is that its function is very important. It is vital for customers to better use industrial equipment. In the traditional system, the internal card of the electronic computer (printed circuit board) uses a very uneven digital-to-analog converter to perform this daily task. The working principle is that the voltage generated by each high-voltage voltage divider is converted into a capacitor battery charging battery. The power capacitor is a simple electronic component to store positive charge (capacitor principle in detail), adjust the high-voltage divider, the greater the resistance, The longer the charge time of the capacitor battery. The lower the partial voltage resistance, the faster the charging efficiency of the capacitor battery. Charge the capacitor, and then accurately measure the time it takes for the battery to charge the capacitor. According to this method, the converter specific high voltage divider and joystick position, measured the average charging speed of the battery is the computer can recognize the data signal, when the computer must actually operate a part of the joystick, will run the actual operation. Industrial handle is a common electronic device in life, widely used in organic chemistry, food machinery equipment, monitoring system, etc., it is of great help to the operation of industrial equipment, so what kind of industrial handle? Let's take a look. 1. According to the material, it can be divided into plastic parts and cast iron parts, in which the plastic handle is composed of thermosetting plastics and thermoplastics, and the construction steel can be divided into mechanical processing and forging. 2. The handle appearance of industrial control equipment can be divided into handle, linear handle, rotating handle, etc. According to the raw materials of industrial handle, it can be divided into remote rod handle, iron handle, zinc alloy material handle, steel handle, zinc alloy material handle, steel handle, etc. 3. According to the actual operation performance of the handle, it can be divided into handle, rotating handle, clamping handle, adjustable handle, telescopic handle, handle cover, handle support rod, handle seat, rocker, three-ball handle, etc.

Common problems with the use of industrial operating handles

As an important part of the control system of construction machinery, the stable use of industrial operating handles determines the accuracy and stability of human-machine control systems. This issue will briefly explain the common problems and simple troubleshooting methods that industrial operating handles may encounter during use. 1、 Damaged leather cover and cap: Damaged leather covers are currently the most common problem in the use of industrial operating handles. In many harsh working conditions, such as the handle of high-altitude work vehicles and agricultural machinery, the waterproof leather cap on the outside of the handle may be damaged due to various external factors such as welding sparks, mud, and corrosive liquid splashes. At this point, the leather cover has already become invalid. If you continue to use or remove the leather cover for use, The possibility of external pollutants entering the handle and causing damage to the button or electrical performance. There are usually two situations, one is when the leather cap on the upper end of the electronic control handle is damaged. In this case, the leather cap is usually used to protect the upper button or rocker button, and damage to this situation can usually be achieved by replacing the upper leather cap. If the leather cover on the upper end of the electronic control handle is not replaced and continues to be used, it may damage the internal button during future use, resulting in the failure of the upper button on the electronic control handle.

Principle of industrial handle potentiometer

In the industrial handle, there are two main output forms used by the electronic control handle: potentiometer type output and Hall type output. The difference between the potentiometer type and the Hall type of the electronic control handle has been described in the previous article, which is roughly as follows: The characteristic of the Hall type is that it has an active, non-contact operation and a longer lifespan. Not suitable for occasions with metal dust. Most of the potentiometer used on general industrial handles are carbon film potentiometer or metal film potentiometer, which change the resistance by sliding the brush or sliding rod on the carbon film. The key process difficulty lies in the carbon film. The carbon film of the resistor body is coated on the surface of the substrate with ground carbon black, graphite, quartz and other materials. The characteristic is high resolution, good wear resistance, and long service life. The disadvantage is current noise, slightly poor linearity, poor moisture resistance, and resistance stability. Because industrial handles need certain life requirements, and certain operating precision and accuracy, the use of carbon film potentiometer or metal film potentiometer can give consideration to both the service life and operating precision. The relative linear impact and current noise have less impact on the use of industrial handles, and the potentiometer itself and the electric control handle itself will be protected against dust and water, so the disadvantage of moisture resistance will not exist. The industrial joystick potentiometer usually has the following faults according to its use environment: 1. The burning of potentiometer caused by wrong wiring is externally manifested as sparks or potentiometer blackening, heating and burning. 2. Poor contact or breakpoints caused by carbon film damage can be measured using an oscilloscope to capture waveforms. 3. The brush blade is diverted or deformed, usually manifested as a change in linear output or no output.

Common types of industrial joysticks

As a commonly used component in industrial control, industrial joysticks are widely used in engineering machinery, logistics handling machinery, medical machinery, video surveillance, high-altitude operation machinery, agricultural machinery, and other fields. The main function of industrial joysticks is to convert human mechanical actions into electrical signals, achieving human-machine control. The common types of industrial joysticks are classified as follows: 1、 According to the classification of the contact parts between the handle and the operator's hand, industrial joysticks are generally divided into two types: fingertip type handles and grip type handles. Special models such as TW series (finger wheel) and RS series (rotary) are not introduced here due to their limited application. 1. Fingertip handle: Mainly operated with fingers or fingertips, often referred to as a small handle, abbreviated as a "fingertip handle". Our FJ1, FJ3, FJ9S, FJ6, etc. are all finger tip handles. Our company is named with the prefix FJ, with "F" being the initial letter of "Finger" in English and "J" being the initial letter of "Joystick" in English. 2. Grip type handle: As the name suggests, grip the handle with the palm or palm of the hand for operation, usually a large handle; Abbreviated as "grip type handle". The typical representative is HJ60, while others such as HJ30, HJ20, HJ10, HJ8, HJ5, HJ70, HJ80, etc. are all grip type handles. Our company is named after HJ, with "H" being the initial letter of "Hand" in English. 2、 According to the reset method, it is generally divided into two types: self reset handle and friction positioning handle. 1. Self resetting handle: In the operation process, when the handle is released, it will automatically return to the starting position, usually returning to the middle position, and very few products have unilateral reset. Its implementation method is generally based on the spring principle. In our product series, most products are self resetting handles. 2. Friction positioning handle: that is, during the operation process, when the handle is released, the handle stops at the released position. Its working principle is achieved through friction damping between the moving and fixed parts to achieve stop and stop operation. Our company has fewer friction positioning handles, which are generally used in conjunction with tactile structures. In our product series, only the HJ5 series is a pure friction positioning handle. HJ20, HJ21, HJ50, etc. have friction positioning functions;

Classification and typical application of industrial operating rods

The electronic control handle is classified into Hall voltage output handle, potentiometer output handle, wide voltage/current output handle and digital bus output handle according to the output signal. Hall voltage output handle, with an output range of (0-5V), it is generally recommended to choose the output range of (0.5-4.5V). Therefore, when the handle is open circuit or short circuited, and the voltage output becomes "0V" or "5V", the control system can directly determine the handle error, thereby avoiding safety accidents. Potentiometer output type, the output range can be adjusted according to the customer's requirements based on the customer's power supply voltage. Wide voltage/current output handle, specifying input voltage (wide voltage 9-36V input), output voltage or current. Adjust the required output according to the customer's circuit load. The digital bus output handle transmits data signals through bus interfaces (CAN, USB, etc.), and more and more electric control machinery is using this method for signal transmission.
