Technical Field

The invention relates to a motor inspection tool, in particular to a motor dimension inspection tool.

Background

The motor mainly comprises a stator, a rotor, a shell and other components, after the stator, the rotor and the shell are assembled, in order to guarantee subsequent normal use of the motor, the size of the motor needs to be detected, such as the diameter of the motor shell, the height of the motor shell, the length of an extending end of a rotating shaft and the like, the length of the extending end of the rotating shaft is detected by adopting a ruler for direct measurement, so that the labor intensity is high, the measurement error is easy to occur, and the measurement precision is influenced. Therefore, the prior art has the problem of low detection accuracy.

Disclosure of Invention

The invention aims to provide a motor dimension inspection tool. The invention has the characteristic of effectively improving the detection accuracy.

The technical scheme of the invention is as follows: a motor size inspection tool comprises a support, wherein an external threaded pipe is arranged in the middle of the upper end of the support, a qualified product judgment pipe is connected to the external threaded pipe in a threaded mode, and a judgment step is arranged at the upper end of the qualified product judgment pipe; the support includes the intermediate junction pole, and the both ends of intermediate junction pole top are equipped with the fixing base, and the fixing base inboard is equipped with the guide bar, is equipped with the slider on the guide bar, is equipped with the spring between slider and the fixing base, and the slider top is equipped with the connecting rod, and the connecting rod outer end is equipped with the cardboard of vertical distribution.

In the foregoing motor dimension inspection tool, the bottom surface of the intermediate connecting rod is provided with an attracting magnet.

In the motor size inspection tool, the rubber pad is arranged on the inner wall surface of the clamping plate.

In the foregoing motor dimension inspection tool, the bottom of the clamping plate is further provided with guide plates which are distributed obliquely.

Compared with the prior art, the device comprises a support, an external threaded pipe, a qualified product judging pipe and a judging step, the device is only required to be placed on a motor, the protruding length of the rotating shaft is judged through the qualified product judging pipe, the structure is simple, the operation is convenient, the judgment is not easy to make mistakes, and the detection accuracy can be effectively improved. Meanwhile, the qualified product judging pipe and the external threaded pipe are connected through threads, so that the height of the qualified product judging pipe can be adjusted, and the qualified product judging pipe is matched with motor housings with different diameters through mutual matching among the sliding block, the guide rod and the spring, so that the qualified product judging pipe is suitable for motors with different sizes, and the application range is expanded. In conclusion, the invention has the characteristic of effectively improving the detection accuracy.
