Description

Technical Field

[0001] This utility model relates to the field of motor housing technology, and in particular to a coaxiality inspection tool for motor housings. Background Technology

[0002] The coaxiality of the motor housing and the upper and lower covers directly affects the motor assembly and performance. Excessive coaxiality will cause excessive motor vibration and noise. In severe cases, the motor may even become unable to rotate. After the motor housing is manufactured, its coaxiality needs to be checked and tested to ensure better cooperation with the internal parts of the motor during operation, thereby ensuring the stable quality and high efficiency of the motor.

[0003] Upon investigation, a Chinese utility model patent discloses a novel coaxiality testing device for motor housings (publication number: CN222188154U). Although the aforementioned patent can facilitate the clamping and installation of motor housings of different sizes through clamping components, the device can only test one motor housing at a time. After the test is completed, it is necessary to wait for the equipment to stop and the fixing to be released before the material can be removed and a new housing to be tested can be placed. The material removal waiting time is long, which reduces the overall testing efficiency. At the same time, the clamping method is prone to damaging the motor housing. Utility Model Content

[0004] In view of the existing problems that can only inspect one motor housing at a time, and that after the inspection is completed, the equipment must be stopped and the fixing must be released before the material can be picked up and a new housing to be inspected can be placed, the material picking waiting time is long, which reduces the overall inspection efficiency, and the clamping method is prone to damage to the motor housing, this utility model is proposed.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a motor housing coaxiality inspection fixture, including an inspection table, a rotating structure, and a detection structure. The rotating structure and the detection structure are respectively installed on the inspection table. The rotating structure includes a rotating table and a first motor. The motor shaft of the first motor is fixedly connected to the center position of the rotating table. A first mounting groove is provided on the rotating table. A bidirectional lead screw is rotatably installed in the first mounting groove. A rotating handle is fixedly installed at one end of the bidirectional lead screw. A first threaded plate and a second threaded plate are threadedly installed on the bidirectional lead screw. The first threaded plate, the second threaded plate, and the first mounting groove are slidably connected. A first clamping block and a second clamping block are fixedly installed on opposite sides of the first threaded plate and the second threaded plate, respectively.

[0006] As a preferred embodiment of the coaxiality inspection fixture for the motor housing described in this utility model, the rotating table is rotatably mounted on the top of the inspection table, and the top of the rotating table is symmetrically provided with a first bearing area and a second bearing area, the first bearing area and the second bearing area are identical, and the first motor is fixedly mounted on the bottom of the inspection table.

[0007] As a preferred embodiment of the coaxiality inspection tool for the motor housing described in this utility model, the first mounting groove is respectively disposed on the first bearing area and the second bearing area, and one end of the bidirectional lead screw extends through the rotating table to the outside of the rotating table.

[0008] As a preferred embodiment of the coaxiality inspection tool for the motor housing described in this utility model, the inspection structure includes a fixed frame, a second motor, and a rotating shaft. The fixed frame is fixedly installed on the side wall of the inspection table. A second mounting groove is provided inside the fixed frame. A one-way lead screw is rotatably installed in the second mounting groove. The second motor is fixedly installed at the top of the fixed frame, and the motor shaft of the second motor is fixedly connected to the top of the one-way lead screw.

[0009] As a preferred embodiment of the coaxiality inspection tool for the motor housing described in this utility model, a threaded block is threadedly installed on the one-way lead screw, the threaded block is slidably connected to the second mounting groove, and a mounting plate is fixedly installed on the threaded block.

[0010] As a preferred embodiment of the coaxiality inspection tool for the motor housing described in this utility model, a third motor is fixedly installed on the top of the mounting plate, the rotating shaft is rotatably mounted on the mounting plate, and the motor shaft of the third motor and the rotating shaft are fixedly connected.

[0011] As a preferred embodiment of the coaxiality inspection tool for the motor housing described in this utility model, an electric push rod is fixedly installed at the bottom end of the rotating shaft via a support frame. The electric push rod is arranged laterally, and a dial indicator is fixedly installed at the telescopic end of the fixed frame via a connecting frame.

[0012] The beneficial effects of this utility model are: 1. By setting symmetrical and identical first and second bearing areas on the rotating platform, two motor housings can be placed simultaneously. After one motor housing is inspected, the first motor can drive the rotating platform to rotate, so that the uninspected housing is automatically switched to the inspection position, and the inspected housing is rotated out to an area that is easy to pick up. There is no need to wait for the inspection process to end before picking up and putting down the material, which effectively reduces the waiting time for picking up the material and improves the inspection efficiency. With the help of the first clamping block and the second clamping block, the motor housing can be quickly and stably clamped and fixed, ensuring the reliability of the fixation while avoiding damage to the housing and ensuring the integrity of the housing. 2. The dial indicator height can be flexibly adjusted by the second motor to adapt to the testing requirements of motor housings of different specifications by driving the unidirectional lead screw to rotate. With the help of the lateral extension and retraction of the electric push rod, the third motor drives the support frame to rotate through the shaft, which can comprehensively test the motor housing, ensuring the accuracy of the test position, improving the test coverage, and effectively ensuring the reliability of the coaxiality test results.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Example 1 Refer to attached figure Figure 1 - Appendix Figure 3This first embodiment of the present invention provides a coaxiality inspection fixture for a motor housing, including an inspection platform 1, a rotating structure 2, and an inspection structure 3. The rotating structure 2 and the inspection structure 3 are respectively mounted on the inspection platform 1. The rotating structure 2 includes a rotating table 201 and a first motor 202. The rotating table 201 is rotatably disposed at the top of the inspection platform 1. A first bearing area 2011 and a second bearing area 2012 are symmetrically arranged at the top of the rotating table 201. The first bearing area 2011 and the second bearing area 2012 are identical. The first motor 202 is fixedly mounted at the bottom of the inspection platform 1, and the motor shaft of the first motor 202 is fixedly connected to the center position of the rotating table 201. A first bearing area 2011 and the second bearing area 2012 are respectively provided with a first bearing area 2011. The mounting groove 203 has a bidirectional lead screw 204 rotatably mounted inside it. One end of the bidirectional lead screw 204 passes through the rotating table 201 and extends to the outside of the rotating table 201. A rotating handle is fixedly mounted on the outer end of the bidirectional lead screw 204. A first threaded plate 205 and a second threaded plate 207 are threadedly mounted on the bidirectional lead screw 204. The first threaded plate 205, the second threaded plate 207 and the inner wall of the first mounting groove 203 are slidably connected. A first clamping block 206 and a second clamping block 208 are fixedly mounted on opposite sides of the first threaded plate 205 and the second threaded plate 207, respectively. The first clamping block 206 and the second clamping block 208 are a pair of clamps. There are a total of two pairs of first clamping blocks 206 and second clamping blocks 208.

[0017] During use, two motor housings are placed on the first bearing area 2011 and the second bearing area 2012 respectively, between the first clamping block 206 and the second clamping block 208. Rotating the rotary handle drives the bidirectional lead screw 204 to rotate, causing the first threaded plate 205 and the second threaded plate 207 to slide in the first mounting groove 203, thereby driving the first clamping block 206 and the second clamping block 208 to clamp and fix the motor housing. With the cooperation of the detection structure 3, the coaxiality of the motor housing can be detected. After one motor housing is detected, the first motor 202 is started, and the first motor 202 drives the rotating table 201 to rotate, so that the undetected motor housing rotates to the bottom of the detection structure 3. The motor housing that has been detected is then rotated out for easy removal.

[0018] Example 2 Refer to attached figure Figure 4 and attached Figure 5 This is the second embodiment of the present invention, which differs from the first embodiment in that: The detection structure 3 includes a fixed frame 301, a second motor 304, and a rotating shaft 308. The fixed frame 301 is fixedly installed on the side wall of the detection table 1. A second mounting groove 302 is provided inside the fixed frame 301. A one-way lead screw 303 is rotatably installed in the second mounting groove 302. The second motor 304 is fixedly installed on the top of the fixed frame 301, and the motor shaft of the second motor 304 is fixedly connected to the top of the one-way lead screw 303. A threaded block 305 is threadedly installed on the one-way lead screw 303. The threaded block 305 and the second... The mounting slot 302 is slidably connected, and the mounting plate 306 is fixedly installed on the threaded block 305. The top of the mounting plate 306 is fixedly installed with a third motor 307. The rotating shaft 308 is rotatably mounted on the mounting plate 306. The motor shaft of the third motor 307 is fixedly connected to the rotating shaft 308. The bottom of the rotating shaft 308 is fixedly installed with a support frame 309. The electric push rod 310 is fixedly installed on the support frame 309. The electric push rod 310 is arranged horizontally. The telescopic end of the fixed frame 301 is fixedly installed with a dial indicator 311 through a connecting frame.

[0019] During use, the second motor 304 is started, which drives the one-way lead screw 303 to rotate, causing the threaded block 305 and the mounting plate 306 to move up and down along the second mounting groove 302, so that the height of the dial indicator 311 is adjusted to the appropriate detection position for the motor housing. The electric push rod 310 is started, and the electric push rod 310 extends and retracts laterally, so that the probe of the dial indicator 311 is precisely abutted against the part of the motor housing to be tested. The dial indicator 311 provides real-time feedback on the value change. The third motor 307 is started, and the third motor 307 drives the support frame 309 to rotate through the rotating shaft 308, thereby performing a comprehensive test on the motor housing.
