Description

Technical Field

[0001] The utility model belongs to the technical field of motor production equipment, and in particular relates to a motor stator installation detection mechanism. Background Art

[0002] During motor production, the inner wall of the stator needs to be inspected to see if its inner wall position and inner shape are standard. Usually, a detection device is used to rotate it one circle to detect whether there is any contact.

[0003] Since conventional electronic mechanical equipment needs to be controlled by intelligent devices, the manipulator and intelligent device are complex in structure, and the testing process is relatively slow, resulting in the problem of low practicality of conventional motor stator testing equipment.

[0004] To this end, we propose a motor stator installation detection mechanism to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem of relatively low practicability of conventional motor stator testing equipment and proposes a motor stator installation detection mechanism.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A motor stator installation detection mechanism comprises a base, wherein the upper end of the base is symmetrically fixedly connected with a guide sleeve, a bracket is slidably inserted on the guide sleeve, a rotating block is rotatably installed on the middle part of the bracket, the rotating block passes through the bracket, a first threaded bolt and a second threaded bolt are slidably inserted into the lower part of the rotating block, the external threads of the first threaded bolt and the second threaded bolt are installed with a two-way threaded knob, the two-way threaded knob is movably clamped in the lower part of the rotating block, a threaded column is symmetrically threadedly installed on the side of the bracket, the threaded column passes through the bracket and contacts with the bottom of the guide sleeve, a threaded rod is rotatably installed in the base, a positioning rod is symmetrically threadedly installed on the outside of the threaded rod, and the positioning rod slides through the lower part of the guide sleeve. Twist the bidirectional threaded knob to adjust the extension length of the first threaded bolt and the second threaded bolt, so that the first threaded bolt and the second threaded bolt have the same inner diameter as the test standard, then put the stator on the base, lift the rotating block with one hand, so that the rotating block drives the first threaded bolt and the second threaded bolt to rise, and then push the stator between the two positioning rods, loosen the rotating block, and then quickly twist the rotating block, so that the rotating block drives the first threaded bolt and the second threaded bolt to rotate in the stator. When the rotating block rotates smoothly, it means that the inner diameter of the stator is qualified. The detection of the inner diameter of the stator is realized through a simple mechanical structure, which improves practicality.

[0008] Preferably, the upper end of the guide sleeve is fixedly connected with a guide ring. The bracket is inserted into the guide ring, and the bracket is guided into the guide sleeve through the guide ring, so that the bracket and the guide sleeve are conveniently connected.

[0009] Preferably, the upper end of the rotating block is fixedly connected with a first knob. The first knob is pinched by hand, and then quickly rotated, so that the first knob acts on the rotating block, so that the rotating block drives the first threaded bolt and the second threaded bolt to rotate quickly, which facilitates the operation of quickly rotating the first threaded bolt, the second threaded bolt and the rotating block.

[0010] Preferably, the upper end of the threaded column is fixedly connected with a second knob, and the second knob is used to increase the screwing lever length of the threaded column, so as to facilitate manual screwing of the threaded column, screwing the threaded column for adjustment, and conveniently adjusting the placement height of the bracket through the threaded column.

[0011] Preferably, the threaded rod comprises a third knob, a bolt and a rotating shaft, wherein the bolt is symmetrically fixedly connected to the side end of the rotating shaft, and the third knob is fixedly connected to the outer end of the bolt. The third knob is turned to drive the bolt to rotate, and the bolt drives the two positioning rods to retract and extend, so as to facilitate the matching of the positioning rod with the target stator.

[0012] Preferably, the positioning rod comprises a positioning block, a slide and a nut, wherein the positioning block is fixedly connected to the slide, and the nut is fixedly connected to the slide. When the bolt rotates, the bolt drives the nut to move, the nut drives the slide, and the slide acts on the positioning block, so that the threaded rod drives the positioning rod to move.

[0013] Preferably, the bracket includes a bearing, a connecting rod and an insert sleeve, wherein the connecting rod is symmetrically fixedly connected to the outer end of the bearing, and the insert sleeve is fixedly connected to the lower end of the connecting rod. The insert sleeve is inserted into the guide sleeve, and the guide sleeve is used to guide the insert sleeve to descend, and the connecting rod acts on the bearing, and the bearing acts on the rotating block, so that the rotating block is conveniently kept at the center of the target stator.

[0015] 1. Turn the two-way threaded knob to adjust the extension length of the first threaded bolt and the second threaded bolt, so that the first threaded bolt and the second threaded bolt have the same inner diameter as the test standard.

When the rotating block rotates smoothly, it means that the inner diameter of the stator is qualified. The detection of the inner diameter of the stator is realized through a simple mechanical structure, which improves the practicality.

[0016] 2. Pinch the first knob by hand, and then quickly turn the first knob. The first knob acts on the rotating block, so that the rotating block drives the first threaded bolt and the second threaded bolt to rotate quickly, which is convenient for operating the first threaded bolt, the second threaded bolt and the rotating block to rotate quickly.

[0017] 3. Use the second knob to increase the length of the screwing lever of the threaded column, which is convenient for manually screwing the threaded column and adjusting the threaded column. The height of the bracket can be easily adjusted through the threaded column.

[0018] 4. Turn the third knob to drive the bolt to rotate, and the bolt drives the two positioning rods to expand and contract, making it easier to match the positioning rods with the target stator.

[0019] 5. Insert the insert into the guide sleeve, use the guide sleeve to guide the insert to descend, act on the bearing through the connecting rod, and act on the rotating block through the bearing, so as to keep the rotating block in the center of the target stator.
