Description

Technical Field

[0001] This utility model relates to the field of single-machine testing technology, and in particular to a tooling for first eliminating errors and then measuring the motor output shaft clearance. Background Technology

[0002] In the production and maintenance of motors, accurate measurement of the output shaft clearance is crucial. The size of the output shaft clearance directly affects the motor's operational stability, transmission efficiency, and service life. For example, excessive clearance may cause abnormal vibration and noise during motor operation, reduce transmission accuracy, and even lead to premature wear of motor components; while insufficient clearance can easily cause the motor to malfunction due to frictional heat during operation, and in severe cases, may even cause the motor to burn out.

[0003] In the existing technology, traditional motor testing fixtures have significant drawbacks in use. For example, when measuring the output shaft clearance of a motor, the motor is directly fixed using a fixed fixture before measurement. However, the output shaft of the motor has a certain range of motion. If the error is not eliminated, the accuracy of the test will be affected. Therefore, this utility model proposes a fixture that eliminates the error before measuring the output shaft clearance of the motor. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tooling for eliminating errors before measuring the motor output shaft clearance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixture for eliminating errors before measuring the output shaft clearance of a motor includes a fixed plate. A placement plate, a fixed block, and a vertical plate are fixedly connected to the upper end of the fixed plate. The motor to be tested is placed on the placement plate. A clamping mechanism for clamping the motor to be tested is provided on the fixed block. The clamping mechanism includes a pusher that is slidably connected through the fixed block. A pusher head is fixedly connected to the end of the pusher near the motor to be tested, and a handle is fixedly connected to the end of the pusher away from the motor to be tested. The handle is elastically connected to the fixed block by a spring.

[0007] Preferably, a limiting post is fixedly connected to one end of the placement plate near the fixing block, the upper end of the limiting post is provided with a limiting groove, and the upper end of the placement plate is provided with a V-shaped groove.

[0008] Preferably, a connecting column is fixedly connected to the side wall of the vertical plate, and the connecting column is hollow.

[0009] Preferably, the vertical plate has a through hole, which is coaxial with the connecting column, and a measuring head is slidably connected inside the connecting column.

[0010] Preferably, a measuring instrument is fixedly connected to the end of the connecting column, and a measuring telescopic rod is provided on the side wall of the measuring instrument, with the telescopic end of the measuring telescopic rod fixedly connected to the end of the measuring head.

[0011] Preferably, the measuring head mates with the through hole, and a limiting block is fixedly connected to the end of the placement plate away from the limiting post.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] By setting up a clamping mechanism, when measurement is required, pulling the handle moves the abutment column to the left, which in turn moves the abutment head to the left, placing the motor under test into the V-groove and the limiting groove. Then, releasing the handle causes the handle and abutment column to reset under the action of the spring, which in turn resets the abutment head, squeezing the motor under test and pushing it to move. This limits the movement of the motor under test, causing it to press against the limiting block. Then, starting the measuring instrument causes the telescopic end of the measuring rod to move, which in turn moves the measuring head, pressing against the output shaft of the motor under test. This eliminates errors in the output shaft of the motor under test, greatly improving measurement accuracy. Attached Figure Description

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Reference Figure 1-6 A fixture for eliminating errors before measuring the motor output shaft clearance includes a fixed plate 1. The upper end of the fixed plate 1 is fixedly connected to a placement plate 12, a fixed block 4, and a vertical plate 2. The motor to be tested 3 is placed on the placement plate 12. The fixed block 4 is provided with a clamping mechanism for clamping the motor to be tested 3. The clamping mechanism includes a pusher 9 that is slidably connected through the fixed block 4. A pusher head 10 is fixedly connected to the end of the pusher 9 near the motor to be tested 3. A handle 5 is fixedly connected to the end of the pusher 9 away from the motor to be tested 3. The handle 5 is elastically connected to the fixed block 4 by a spring 8.

[0023] Specifically, a limiting post 11 is fixedly connected to one end of the placement plate 12 near the fixing block 4. A limiting groove 14 is formed at the upper end of the limiting post 11, and a V-shaped groove 15 is formed at the upper end of the placement plate 12.

[0024] Specifically, a connecting column 6 is fixedly connected to the side wall of the vertical plate 2. The connecting column 6 is hollow and has a through hole on the vertical plate 2. The through hole is coaxial with the connecting column 6 and a measuring head 13 is slidably connected inside the connecting column 6.

[0025] Specifically, a measuring instrument 7 is fixedly connected to the end of the connecting column 6. A measuring telescopic rod 701 is provided on the side wall of the measuring instrument 7. The telescopic end of the measuring telescopic rod 701 is fixedly connected to the end of the measuring head 13. The measuring head 13 cooperates with the through hole. A limit block is fixedly connected to the end of the placement plate 12 away from the limit column 11. It should be noted that the design of the V-groove 15 and the limit groove 14 needs to be compatible with the motor under test 3. The output shaft of the motor under test 3 is coaxial with the through hole.

[0026] When using this invention, to measure, pull the handle 6 to move the abutment 9 to the left, which in turn moves the abutment head 10 to the left, placing the motor under test 3 into the V-groove 15 and the limiting groove 14. Then, release the handle 5, and under the action of the spring 8, the handle 5 and the abutment 9 will reset, and the abutment head 10 will reset, squeezing the motor under test 3 and pushing it to move, thus limiting the motor under test 3 and making it press against the limiting block. Then, start the measuring instrument 7, which moves the telescopic end of the measuring telescopic rod 701, causing the measuring head 13 to move and press against the output shaft of the motor under test 3. This can eliminate errors in the output shaft of the motor under test 3 and greatly improve the measurement accuracy.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
