Description

Technical Field

[0001] This utility model relates to the field of motor stator lamination production technology, and in particular to a motor stator lamination placement fixture. Background Technology

[0002] The motor stator is an important component of motors such as generators and starters. It is a crucial part of the electric motor. The motor stator consists of three parts: the stator core, the stator windings, and the frame. The main function of the motor stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force within this rotating magnetic field, thereby generating an electric current. Motor stator laminations are used as materials in the production of electric motors.

[0003] After the motor stator is produced, the common method is to place the stator directly into the material frame. The stator is placed in a messy manner, which is not conducive to subsequent processing. Another method is for the workers to place the stator laminations on the column. The limiting of stator laminations of different sizes is relatively cumbersome, and it is also inconvenient to remove them after they are stacked. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a tooling for placing motor stator laminations, thereby solving the problems mentioned in the background art.

[0005] A fixture for placing stator laminations of an electric motor includes a base and a limiting mechanism mounted on the base. The limiting mechanism includes a rotating table, limiting components, a support platform, a ring, a hydraulic cylinder, a fixed sleeve, a limiting post, and an adjusting rod. The rotating table is rotatably mounted on the top of the base, and multiple placement openings are provided around the rotating table. The support platform is movably mounted in the middle of the base, and the ring is fixed to the bottom of the support platform. Multiple limiting components are provided, each corresponding to one of the placement openings, and are fixed to the support platform. The output end of the hydraulic cylinder is slidably connected to the ring via a slider. The fixed sleeve is mounted in the middle of the rotating table. Multiple sets of adjusting rods are provided, each corresponding to one of the multiple sets of limiting components, and are rotatably mounted on the fixed sleeve. The limiting post is rotatably connected to the adjusting rod.

[0006] The limiting assembly includes a fixed plate, a connecting shaft, a limiting part, a fixed cylinder, a bidirectional lead screw, a moving block, and a connecting arm. The fixed cylinder is fixedly installed on the fixed plate. The connecting shaft is installed on both sides of the lower end of the fixed cylinder. The limiting parts are positioned opposite each other on both sides of the fixed cylinder and slide along the connecting shaft. The bidirectional lead screw is rotatably installed in the fixed cylinder. The moving blocks are two opposite blocks that slide in the fixed cylinder and are connected to the bidirectional lead screw. The moving blocks and the limiting parts on the corresponding side are hinged through the connecting arm.

[0007] By adopting the above technical solution, it is easier to place the stator laminations and adjust their positions, and it is also easier to remove the stacked stator laminations afterward.

[0008] The placement opening is also fixedly mounted on the top surface of the rotating platform on both sides of the platform.

[0009] By adopting the above technical solution, the stator laminations are supported, making them easier to remove later.

[0010] The cross-section of the limiting part is an arc-shaped structure, and it is symmetrically arranged with respect to the central axis of the bidirectional lead screw.

[0011] By adopting the above technical solution, the inner ring of the stator lamination is limited.

[0012] The limiting post is rotatably mounted on the fixed sleeve via two adjusting rods, and the limiting post is set in a vertical position.

[0013] The limiting column is adjusted by adopting the above technical solution.

[0014] The upper and lower ends of the inner wall of the limiting part are each hinged with two sets of connecting arms, each set of connecting arms has two arms, and they are hinged to the moving block through a connecting rod.

[0015] By adopting the above technical solution, it is possible to adjust the limiting part to limit the inner ring of the stator lamination.

[0016] The beneficial effects of this utility model of motor stator lamination placement fixture are:

[0017] The stator laminations are positioned by limiting components from the inner ring, and the limiting posts help to place the stator laminations neatly. After one set of limiting components is in place and stacked, the rotary table and support can be rotated synchronously to move the other set of limiting components to the corresponding position. The stacking can then be continued using external robotic arms or other equipment. When removing the stacked stator laminations, the limiting components are simply pulled downwards by a hydraulic cylinder to disengage them from the inner ring of the stator laminations, allowing the stator laminations to be removed. This device facilitates the placement of stator laminations and makes it easy to remove the stacked stator laminations afterward. Attached Figure Description

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0023] Reference Figure 1-3 A fixture for placing stator laminations of an electric motor includes a base 1 and a limiting mechanism mounted on the base 1. The limiting mechanism includes a rotary table 2, limiting components 4, a support 5, a ring 6, a hydraulic cylinder 7, a fixed sleeve 8, a limiting post 9, and an adjusting rod 10. The rotary table 2 is rotatably mounted on the top of the base 1, and multiple placement openings 201 are provided around the rotary table 2. The support 5 is movably mounted in the middle of the base 1, and the ring 6 is fixed to the bottom of the support 5. Multiple limiting components 4 are provided, each corresponding to one of the placement openings 201, and are fixed on the support 5. The output end of the hydraulic cylinder 7 is slidably connected to the ring 6 via a slider. The fixed sleeve 8 is mounted in the middle of the rotary table 2. Multiple sets of adjusting rods 10 are provided, each corresponding to one of the multiple sets of limiting components 4, and are rotatably mounted on the fixed sleeve 8. The limiting post 9 is rotatably connected to the adjusting rod 10.

[0024] The limiting assembly 4 includes a fixed plate 401, a connecting shaft 402, a limiting part 403, a fixed cylinder 404, a bidirectional lead screw 405, a moving block 406, and a connecting arm 407. The fixed cylinder 404 is fixedly installed on the fixed plate 401. The connecting shaft 402 is installed on both sides of the lower end of the fixed cylinder 404. The limiting part 403 is placed opposite to both sides of the fixed cylinder 404 and slides along the connecting shaft 402. The bidirectional lead screw 405 is rotatably installed in the fixed cylinder 404. The moving blocks 406 are two opposite sliding blocks in the fixed cylinder 404 and are connected to the bidirectional lead screw 405. The moving blocks 406 and the limiting part 403 on the corresponding side are hinged through the connecting arm 407.

[0025] The stator lamination can be pre-installed on the limiting component 4 and placed on the base plate 3. The limiting post 9 is rotatably installed on the fixed sleeve 8 through two adjusting rods 10, and the limiting post 9 is set in a vertical state. Rotating the adjusting rod 10 pushes the limiting post 9 to be stuck in the outer ring groove of the stator lamination. The upper and lower ends of the inner wall of the limiting part 403 are hinged with two sets of connecting arms 407. Each set of connecting arms 407 has two arms, which are hinged to the moving block 406 through the connecting rod. Rotating the bidirectional screw 405 drives the two moving blocks 406 to move relative to each other along the fixed cylinder 404, and then pushes the limiting part 403 to move along the connecting shaft 402 through the connecting arms 407, expanding the distance between the two limiting parts 403. The limiting part 403 limits the inner ring of the stator lamination (it should be noted that the limiting component 4 only needs to contact the inner ring of the stator lamination, or a distance of 1-3 mm can be left between it and the inner ring of the stator lamination).

[0026] At this point, the stator laminations can be placed one by one on the base plate 3 and stacked using external robotic arms and other equipment. During stacking, the rotary table 2 and the support table 5 can be rotated to adjust the position of the next set of limiting components 4 for stacking.

[0027] The limiting part 403 has an arc-shaped cross-section and is symmetrically arranged around the central axis of the bidirectional lead screw 405, which facilitates limiting from the inner ring of the stator lamination. When it needs to be removed later, the bidirectional lead screw 405 can be slightly rotated in the reverse direction to create distance between the limiting component 4 and the inner ring of the stator lamination. This drives the hydraulic cylinder 7 to move the support platform 5 downward, and the support platform 5 simultaneously moves the limiting component 4 downward, so that the limiting component 4 is completely moved below the rotary table 2. The stator lamination can then be removed from the rotary table 2. During the removal of the stator lamination, the rotary table 2 can be rotated to adjust its position for easy removal of the stator lamination.

[0028] The two sides of the placement port 201 are also fixedly installed with base plates 3 on the upper surface of the rotary table 2. The base plates 3 can separate the stator laminations from the upper surface of the rotary table 2 so that the stator laminations can be removed later.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
