Description

Technical Field

[0001] The utility model belongs to the technical field of parts detection, and in particular relates to a detection tool for a stepping motor. Background Art

[0002] The motor shaft is one of the core parts of the motor, mainly used to transmit power and carry loads. The motor shaft end runout amplitude is an important parameter to measure the quality of the motor. The larger the motor shaft end runout amplitude, the greater the swing amplitude of its rotation, which causes deviation and makes the motor rotation unstable. Therefore, in the motor shaft production process, the runout amplitude of the motor shaft raw material needs to be tested.

[0003] The existing motor shaft runout amplitude detection usually uses a bracket to fix the micrometer for measurement. During the measurement process, the bracket needs to be repeatedly adjusted and re-fixed to make the micrometer contact with the motor shaft. This makes the existing equipment time-consuming and inefficient during detection.

[0004] Therefore, in order to solve the above problems, it is necessary to design a detection tool for stepper motors. Utility Model Content

[0005] The utility model aims to provide a detection tool for a stepping motor, so as to solve the technical problem that a lot of time is wasted during the debugging of the existing detection equipment.

[0006] In order to solve the above technical problems, the utility model provides a detection tool for a stepper motor, comprising:

[0007] A support assembly, comprising: a vertical rod and a horizontal rod slidably connected to the vertical rod;

[0008] The positioning assembly comprises: a positioning plate connected to the crossbar;

[0009] The positioning plate is provided with an arc-shaped portion;

[0010] A measuring assembly comprising: a micrometer connected to a crossbar;

[0011] The highest point of the arc-shaped portion is flush with the lowest point of the micrometer;

[0012] The cross bar is suitable for sliding down naturally along the vertical bar to stop when the highest point of the arc portion contacts the highest point of the motor shaft, so that the lowest point of the dial gauge contacts the surface of the motor shaft.

[0013] Furthermore, the support assembly further comprises: an opening locking block sleeved on the vertical rod;

[0014] The opening locking block is slidably connected to the vertical rod; and

[0015] One side of the opening locking block is connected to the cross bar.

[0016] Furthermore, the positioning assembly further comprises: a first opening locking ring sleeved on the crossbar, a first connecting rod connected to the first opening locking ring, and a supporting plate connected to the other end of the first connecting rod; wherein

[0017] The first opening locking ring is slidably connected to the cross bar; and

[0018] The supporting plate is slidably connected to the positioning plate.

[0019] Furthermore, the positioning plate comprises: two symmetrically arranged half plates;

[0020] The arc-shaped portion is composed of two symmetrically arranged half plates.

[0021] Furthermore, two dovetail grooves are symmetrically arranged at the bottom of the support plate;

[0022] The positioning assembly further includes: a slider which is slidably connected to the two dovetail grooves;

[0023] The bottoms of the two sliding blocks are respectively connected to the tops of the corresponding half plates; and

[0024] The two half plates are suitable for being separated when the highest point of the arc-shaped portion contacts the highest point of the motor shaft.

[0025] Furthermore, magnetic blocks are embedded on the contact surfaces of the two half plates respectively;

[0026] The two half plates are adapted to attract the two magnetic blocks when in contact.

[0027] Furthermore, the measuring assembly further comprises: a second opening locking ring sleeved on the cross bar, and a second connecting rod connected to the second opening locking ring; wherein

[0028] The second opening locking ring is slidably connected to the cross bar; and

[0029] The other end of the second connecting rod is connected to the dial indicator.

[0030] Furthermore, the support assembly further comprises: a magnetic seat;

[0031] The top of the magnetic base is connected to the vertical rod.

[0032] The beneficial effects of the utility model are:

[0033] (I) The utility model absorbs the magnetic seat on the motor, loosens the open locking block, so that the open locking block slides naturally down along the vertical rod, and stops when the highest point of the arc portion contacts the highest point of the motor shaft, so that the lowest point of the micrometer contacts the surface of the motor shaft. At this time, the open locking block is tightened to fix the position of the cross bar. At this time, the two half plates are separated, and the two half plates drive the sliders to slide in the dovetail groove and move away from each other. At this time, the micrometer contacts the motor shaft, and the two half plates do not contact the motor shaft, which does not affect the normal measurement of the motor shaft. Through the above steps, the debugging time is reduced, the positioning measurement is fast, and the detection efficiency is improved.
