They improve processing efficiency and product quality through precise and stable positioning.

[0003] After production, the motor end cover rack injection molded part needs to undergo precise testing to ensure it meets dimensional requirements and can be used on motor equipment. This requires inspection and measurement using a fixture. The rack groove, as a crucial mechanical structure, is a necessary aspect for fixture inspection. However, because the motor end cover rack injection molded part is integrally cast, excess or missing parts are prone to occur during the casting process, making it difficult for suspended fixtures to accurately inspect it and affecting the accuracy of the measured data. Therefore, to address these issues, a fixture positioning device for the motor end cover rack injection molded part is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] A fixture positioning device for an injection molded part of a motor end cover rack, including a fixing device 1, a sensing element 2 and a detection probe 3. The fixing device 1 is fixedly connected with the sensing element 2 on the outside. The detection probe 3 is arranged on the outside of the lower end of the sensing element 2. The sensing element 2 is fixedly connected with a positioning component 4 on the outside. The positioning component 4 includes a movement control mechanism 41. The movement control mechanism 41 includes a fine-tuning spring 411. One end of the fine-tuning spring 411 away from the center of the sensing element 2 is fixedly connected with a threaded ring 412. A threaded shaft 413 is spirally connected inside the threaded ring 412. One end of the threaded shaft 413 is fixedly connected with a knob 414 on the outside. The other end of the knob 414 is fixedly connected with a limiting disk 415 at the end. A moving frame 416 is arranged on the outside of the limiting disk 415. A limiting mechanism 42 is fixedly connected with the outside of the lower end of the moving frame 416. The limiting mechanism 42 includes a fixed baffle 421. A connecting spring 422 is fixedly connected with the outside of the lower end of the fixed baffle 421. One end of the connecting spring 422 away from the fixed baffle 421 is fixedly connected with a moving baffle 423. A sliding ball 424 is slidably connected inside the moving baffle 423.

[0028] As a further implementation of this solution, there are two fine-tuning springs 411 in total. The fine-tuning springs 411 are symmetrically arranged on both sides of the sensing element 2. The fine-tuning springs 411 are sleeved on the outside of the threaded shaft 413. This design provides balanced support, enhancing the stability of the sensing element 2 and the accuracy of adjustment.

[0029] As a further implementation of this solution, the threaded shaft 413 is arranged inside the moving frame 416. One end of the threaded shaft 413 fixedly connected with the knob 414 penetrates through the moving frame 416. One end of the threaded shaft 413 fixedly connected with the limiting disk 415 rotates inside the moving frame 416, ensuring the synchronous movement of the knob 414 and the limiting disk 415 and improving the operation accuracy of the device.

[0030] As a further implementation of this solution, the limiting disk 415 rotates inside the moving frame 416. The diameter of the limiting disk 415 is 1.2 times the thickness of the moving frame 416. The limiting disk 415 is arranged on the side of the fixed baffle 421 close to the center of the moving frame 416. By increasing the diameter, the stability of the limiting disk 415 is enhanced, and at the same time, the frictional interference with the moving frame 416 is reduced.

[0031] As a further implementation of this solution, the cross-section of the moving frame 416 is in the shape of a "hui" character. The moving frame 416 slides on the outside of the sensing element 2. The moving frame 416 and the fixed baffle 421 are perpendicular to each other, increasing the strength of the structure and allowing smooth sliding on the outside of the sensing element 2.

[0032] As a further implementation of this solution, there are several connecting springs 422. The connecting springs 422 are placed inside the movable baffle 423. The connecting springs 422 are evenly distributed directly below the fixed baffle 421, providing uniform support force, reducing local stress, and facilitating elastic control of the position of the movable baffle 423.

[0033] As a further implementation of this solution, the movable baffle 423 slides outside the fixed baffle 421, and a number of sliding balls 424 are evenly distributed on the inner side of the movable baffle 423. The sliding balls 424 are on the same horizontal plane, and a quarter of the sliding balls 424 protrude from the lower end of the movable baffle 423, which reduces sliding friction and improves the moving efficiency and stability of the movable baffle 423.

[0034] Workflow: When using this fixture positioning device to inspect the motor end cover rack injection molded part, the motor end cover rack injection molded part is fixed and restricted under the fixture. Then, when the inspection probe 3 of the fixture acts on the motor end cover rack injection molded part, the knob 414 on the outside of the sensing element 2 can be rotated according to the side position of the motor end cover rack injection molded part. This causes the knob 414 to control the threaded shaft 413 fixedly connected to it to rotate in the movable frame 416 tightly attached to the outside of the sensing element 2, and the threaded shaft 413 passes through its end... The fixedly connected limiting plate 415 rotates stably within the moving frame 416. Because the threaded shaft 413 and the sensing element 2 are fixedly connected to the threaded ring 412 via a fine-tuning spring 411, they have a helical connection. The threaded shaft 413 also passes through the sensing element 2. Therefore, as the threaded shaft 413 rotates, it passively drives the moving frame 416 to move horizontally relative to the sensing element 2. This allows the positioning assembly 4 on the fixture to be displaced as a whole, enabling the operator to control the moving baffle 42 in the limiting mechanism 42. 3. The moving baffle 423 is always in close contact with the outside of the motor end cover rack injection molded part when the detection probe 3 moves. Simultaneously, during the downward detection movement of the detection probe 3 towards the motor end cover rack injection molded part, the sliding ball 424 in the moving baffle 423 is in close contact with the platform on which the motor end cover rack injection molded part is placed. The moving baffle 423 can slide outside the fixed baffle 421 and elastically compress the connecting spring 422 on its inner side to facilitate movement. The baffle 423 can better fit the injection molded part of the motor end cover rack. The slider 424 in the movable baffle 423 is always in close contact with the platform surface, ensuring the smooth movement of the detection probe 3. When the movable baffle 423 encounters obstruction, the movable frame 416 can appropriately stretch and compress the fine adjustment springs 411 on both sides of the sensing element 2 through the connection between the threaded shaft 413 and the threaded ring 412, so that the movable baffle 423 still has good positioning and following movement performance as the detection probe 3 works.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
