Sharing of common techniques for the assembly and debugging of motor assembly equipment

The basic tuning skills for motor assembly equipment are “level, vertical, concentric”. First of all, whether you are debugging any product or not, we must understand its characteristics as well as the customer’s technical requirements. Next, I will introduce to you the common debugging techniques for motor assembly equipment. 1. Understand the product characteristics of motor assembly equipment (including appearance, dimensions, tolerances, structure, manufacturing processes, etc.). 2. Wipe the components (including standard and non-standard ones), identify the most critical components, and then start assembly and debugging from those core components. During the assembly process, the accuracy of the components to be tested should be checked to ensure there are no issues with levelness, perpendicularity, and concentricity. 3. The motor mounting equipment, for single-cylinder pushing, pulling, or lifting components, must ensure that the pulling force is sufficient, the pushing force is also sufficient, and there is no abnormal resistance. 4. The rotating components of the motor assembly equipment should ensure the balance, verticality, and concentricity of these components. To achieve the accuracy of indexing for the swing arm. 5. The pins and sockets of the pin slots and socket slots in the motor assembly equipment should be wiped clean. Select an appropriate pin (with a pin material hardness of over 58 HRC) and position it. The pin should be equipped on one side to facilitate disassembly and assembly. The precision of the slot should be kept within 0.02 to ensure the accuracy of the secondary assembly; it should not be too large or too tight. If it is too large, there is no precision. If it’s too tight, it cannot be assembled. 6. The feeding section is primarily based on the product, with a tolerance range of about 0.1. The motor assembly equipment ensures that the product passes through the material channel without any resistance. Depending on the product, the feed direction of the interface and its edges require a chamfer of 0.2*30 degrees. The interior of the material path needs to be polished to prevent scratching and damaging the product. 7. Special attention should be paid to the nuts and slides when assembling screws and slides. Do not slip out of the screw and slide rail, to prevent the ball from falling out and causing the product to become unusable or affecting its accuracy. After assembly, ensure the parallelism, perpendicularity, and concentricity of the parts prior to assembly. To prevent substandard components from being used in the assembly process via the fixtures, fixing screws, and slides of the custom automation equipment, as well as from ending up as waste. 8. Valve speed adjustment: The speed of the valve should be optimal when the product is removed without affecting production efficiency. If the valve speed is too fast, the motor-driven equipment will vibrate or shake the product; if it is too slow, production efficiency will be reduced. (Note: We usually use an exhaust throttle valve.) 9. Common component adjustments and troubleshooting: a. Magnetic switch (commonly referred to as a sensor), which detects the front and rear parts of the cylinder. Before adjustment, the front part feels pushed to the front end of the cylinder, and the cylinder stroke should also be at the front end. At this time, the sensors of the motor assembly equipment should be turned off, and it is appropriate to push the sensors from the front end to the back end. The method for adjusting the sensation is the same as mentioned above. Bay optical fibers are adjusted according to different brand specifications, and the operations vary, but the principle remains the same; pay attention to the difference between reflective fibers and opposing fibers. C. Vibrating plate: Direct vibration of the vibrating plate is divided into two parts: the vibration part and the control part. The vibration part mainly consists of the vibrating magnet, while the control part is the vibration controller, which has a power switch button as well as buttons for adjusting voltage and frequency. If the vibration frequency is too high, the product will vibrate or move back; if the vibration frequency is too low, the custom automation equipment product will move or fail to move. If the vibration frequency and voltage are adjusted to their maximum, the vibrating plate or the direct vibration will still move slightly. It should be checked whether the gap between the electromagnet and the steel plate is loose or damaged. The optimal gap between electromagnets is between 0.5 and 1 mm. Please make the appropriate adjustments; these are some simple debugging techniques. When assembling motor mounting equipment, using these techniques in a rational and flexible manner can help you complete the debugging process quickly and successfully. Improve corporate economic efficiency and reduce the production costs of motor assembly equipment.
