How to analyze and troubleshoot the motor motor automatic rotor spot welding test machine?
Motor motor automatic rotor spot welding test machine failure, from mechanical, electrical, software and other aspects of the analysis and troubleshooting, the following are specific methods:
1, the mechanical part
Failure phenomenon: rotor clamping is not firm or inaccurate positioning.
Possible causes: fixture wear, deformation or not adjusted; positioning sensor failure.
Elimination methods: check the fixture, such as wear or deformation in time to replace or repair, re-adjust the position of the fixture; check the positioning sensor, clean up the sensor surface debris, if damaged, then replace.
Failure phenomenon: spot welding electrode wear fast or welding pressure is not stable.
Possible causes: poor quality of electrode material; welding parameters are not set reasonably; pressure regulator failure.
Remedy: Replace the electrode material with good quality; optimize the welding parameters, such as current, time, pressure, etc.; check the pressure regulating mechanism, repair or replace the damaged parts.
Failure phenomenon: abnormal noise or vibration when the equipment is running.
Possible causes: loose mechanical parts, wear and tear or poor lubrication; motor or transmission mechanism failure.
Elimination methods: check and tighten the loose mechanical parts, repair or replace the worn parts, add lubricant regularly; check the motor and transmission mechanism, such as belts, chains, gears, etc., repair or replace the damaged parts.
2、Electrical part
Failure phenomenon: the equipment can not start or part of the function fails.
Possible causes: power supply failure; poor wiring connections; control board or drive damage.
Troubleshooting methods: check the power socket, switch and fuse to ensure that the power supply is normal; check the line connection, re-plugging or welding loose connectors; use professional tools to detect the control board and driver, if damaged, replace the corresponding parts.
Fault phenomenon: spot welding current is unstable or abnormal.
Possible causes: welding power supply failure; current sensor failure; abnormal control program.
Troubleshooting methods: check the output voltage and current of the welding power supply, repair or replace the power supply module; check the current sensor, replace it if it is faulty; check the control program, re-download or update the program if it is wrong.
Fault phenomenon: equipment leakage phenomenon.
Possible causes: Electrical line insulation damage; poor grounding.
Troubleshooting methods: check the electrical line, repair or replace the insulation damage; ensure that the equipment is well grounded, check whether the grounding wire is firmly connected.
3、Software
Failure phenomenon: no response or abnormal display of the equipment operating interface.
Possible causes: software program error; computer system failure.
Troubleshooting methods: close and restart the device software, if the problem persists, try to update the software version; check the computer system, clean up junk files, check and kill viruses, reinstall the operating system if necessary.
Failure phenomenon: test data is inaccurate or can not be recorded normally.
Possible causes: communication failure between the sensor and the software; software setting error.
Troubleshooting methods: check the communication line between the sensor and the computer to ensure that the connection is normal; check the data acquisition and recording settings in the software, and reset the correct parameters.
Failure phenomenon: the device suddenly stops during operation or an error message appears.
Possible causes: the software triggered the protection mechanism; program logic errors.
Troubleshooting: Find the reason according to the error message, such as exceeding the parameter range, equipment overload, etc., adjust the corresponding parameters or solve the problem and restart the equipment; check the logic of the program, if there is an error, contact the software developer for repair.
