What are the common mechanical failures and solutions for brushless motor motor automatic press-fit end-capping machine?
Brushless motor motor automatic press-fitting end-capping machine common mechanical failures and solutions are as follows:
First, the transportation system failure
1, end cap transportation jam
Failure performance: the end cap does not move smoothly on the conveying track, there is a phenomenon of stagnation, stuck, affecting the efficiency and continuity of the press-fitting.
Failure causes: conveying track foreign objects into, such as iron filings, dust, debris and other obstacles to the movement of the end of the cover; track surface wear or uneven, increasing the friction between the end of the cover and the track; conveying chain or belt loosening, tension inconsistency, resulting in unstable power transmission.
Solution: clean up the conveying track in time to remove foreign objects; repair or replace the worn track surface; adjust the tension of the chain or belt to make it even and appropriate to ensure the smooth transmission of power.
2、End cover positioning is not allowed
Failure performance: when the end cover is conveyed to the press-fit position, the position deviates and cannot be accurately aligned with the motor body, resulting in poor press-fit quality and possible end cover tilt, press-fit not in place and other problems.
Failure causes: the position of the positioning sensor is shifted or damaged, and the position of the end cap cannot be detected accurately; the transmission parts of the conveying mechanism are worn out, such as gears, screws, etc., resulting in a decrease in the conveying accuracy; the end cap is subjected to collision or vibration by external forces during the conveying process, which changes its original position.
Solution: Re-calibrate the position of the positioning sensor to ensure that it accurately detects the end cap; check and replace the worn transmission parts to restore the conveying accuracy; optimize the conveying environment to reduce the interference of external forces, for example, increase the buffer device or adjust the conveying speed.
Second, the press fitting mechanism failure
1、Insufficient or unstable pressing force
Failure performance: the end cap can not be completely pressed into the motor body, or pressure fluctuations in the press fitting process, resulting in the end cap and the motor body is not tightly combined, affecting the overall performance and stability of the motor.
Failure causes: hydraulic system or pneumatic system pressure is not enough, may be the oil pump failure, air pump air supply is not enough, improper adjustment of the pressure regulator valve and other reasons; press-fitting mold wear, and the end cover of the contact area and the precision of the fit changes, resulting in the pressure dispersion; mechanical transmission components there are gaps or loose, so that the press-fitting force in the transmission process loss.
Solution: check the hydraulic or pneumatic system, repair or replace the faulty oil pump, air pump, adjust the pressure regulator valve to the appropriate pressure value; replace the worn press-fit mold to ensure that it is a good fit with the end cap; fasten the mechanical transmission components, eliminate the gap, to ensure that the press-fit force is effectively transmitted.
2、Pressing and installing position deviation
Failure performance: the relative position of the end cover and the motor body does not meet the requirements after press-fitting, and there are problems such as center deviation and angle deviation, which affect the assembly quality and subsequent use of the motor.
Failure causes: the press-fitting mold is not firmly installed, displacement occurs in the process of press-fitting; the guide mechanism is worn or damaged, can not effectively guide the press-fitting action, so that the end cap in the process of press-fitting deviation from the correct position; the motor body is inaccurate in positioning, resulting in press-fitting deviation from the benchmark.
Solution: Reinstall and tighten the press-fitting mold to ensure its accurate position; check and repair the guiding mechanism, and replace the worn parts if necessary; optimize the positioning device of the motor body to improve the positioning accuracy.
Third, the failure of the clamping mechanism
1、Insufficient clamping force
Failure performance: In the process of press-fitting, the clamping mechanism can not firmly fix the motor body or end cover, resulting in displacement of the end cover during press-fitting, affecting the quality of press-fitting.
Failure causes: clamping cylinder or cylinder seals are damaged, resulting in pressure leakage, the clamping force decreased; clamping block wear, and the motor body or end cover of the contact area is reduced, the friction is insufficient; clamping mechanism of the transmission components are damaged, can not effectively transfer the power to the clamping block.
Solution: Replace the damaged seals to ensure that the pressure of the cylinder or cylinder is normal; repair or replace the worn clamping block to increase the contact area and friction; check and repair the transmission components to ensure the effective transmission of the clamping force.
2, inaccurate clamping position
Failure performance: the clamping mechanism can not accurately clamp the motor body or end cover, resulting in uneven force in the end cover in the process of press-fitting, deformation or press-fitting is not in place.
Failure causes: the positioning device of the clamping mechanism is loose or damaged, unable to accurately determine the clamping position; the clamping block is not properly adjusted, and the shape of the motor body or end cover does not match; the parameters of the control system are set incorrectly, resulting in inaccurate clamping action.
Solution: tighten or replace the positioning device to ensure its accuracy and reliability; adjust the clamping block according to the shape of the motor body and end cover to make it fit closely; reset the parameters of the control system to ensure the accuracy of the clamping action.
Fourth, transmission parts failure
1、Belt, chain wear or broken
Failure performance: abnormal noise when the equipment is running, transmission efficiency decreases, and even lead to equipment can not work properly.
Failure causes: belt, chain long-term use, natural wear and tear; transmission process is overloaded, more than the belt, chain capacity; belt, chain tension is not appropriate, too tight or too loose will accelerate its wear.
Solution: Regularly check the wear and tear of belt and chain, and replace the worn or broken parts in time; reasonably adjust the load of the equipment to avoid overloading; adjust the tension of belt and chain to make them in proper working condition.
2、Gear transmission failure
Failure performance: noise and vibration increase in the transmission process, gear wear increases, which will lead to serious gear damage, affecting the normal operation of the equipment.
Failure causes: poor lubrication of the gear, the friction between the teeth increases, accelerating wear; gear installation is not accurate, uneven meshing gap, resulting in excessive local force; gear material or heat treatment process is not qualified, strength and wear resistance is insufficient.
Solution: Regular lubrication of gears, select the appropriate lubricant and lubrication; reinstallation of gears, adjust the meshing gap, to ensure uniform force; replacement of qualified gears to ensure that its strength and wear resistance to meet the requirements.
