[0027] Reference Figures 1-4 This utility model provides a motor housing turning, milling, and drilling fixture, which includes a base plate 1, a placement platform 15 disposed above the base plate 1, multiple sets of mounting horizontal plates 5 disposed above the placement platform 15 and arranged in three rows, multiple sets of motor housings 4 disposed on the top of the placement platform 15, with each set of motor housings 4 located between two sets of mounting horizontal plates 5, and mounting side seats 6 disposed at the top and bottom of both ends of the mounting horizontal plates 5, with the bottom end of the mounting side seat 6 at both ends of the mounting horizontal plates 5 connected to the top of the limiting slider 3.

[0028] The inner cavity of the mounting side seat 6 is provided with a mounting cavity 9, and a connecting groove 8 is provided on both sides of the mounting side seat 6, and the connecting groove 8 and the inner cavity of the mounting cavity 9 are interconnected.

[0029] The mounting plate 5 has two sets of rollers 13 at the top and bottom, and rotating shafts 7 at both ends of the rollers 13. One end of the rotating shaft 7 passes through the mounting cavity 9 through the connecting groove 8. The rollers 13 can clamp and limit the motor housing 4.

[0030] The inner cavity of the mounting cavity 9 is provided with a telescopic rod 11. Both ends of the telescopic rod 11 are fixedly connected to sliding blocks 10. The sliding blocks 10 are slidably connected to the inner cavity of the mounting cavity 9 and are in contact with the rotating shaft 7. A spring 12 is provided on the surface of the telescopic rod 11, and one end of the spring 12 is connected to one end of the sliding block 10. The spring 12 facilitates the movement of the two sets of sliding blocks 10, thereby driving the rotating shaft 7 to move.

[0031] The mounting side seat 6 has connection holes 14 on both sides, and the connection holes 14 are connected to the inner cavity of the mounting cavity 9.

[0032] The top of the base plate 1 has multiple sets of slide rails 2 and multiple sets of limiting sliders 3 are set at the bottom of the placement platform 15. The limiting sliders 3 are located in the inner cavity of the slide rails 2. The cross-sections of the limiting sliders 3 and the slide rails 2 are both T-shaped. The limiting sliders 3 are slidably connected to the inner cavity of the slide rails 2, which serves to limit the base plate 1 and the placement platform 15.

[0033] During use, the limiting slider 3 is slidably connected to the slide rail 2 on the base plate 1, so that the placement platform 15 can slide above the base plate 1, making it easy to disassemble and assemble the placement platform 15 from above the base plate 1.

[0034] When multiple sets of motor housings 4 are placed on the placement platform 15, the rollers 13 between the two sets of mounting horizontal plates 5 move, thereby driving the rotating shaft 7 to move along the inner wall of the connecting groove 8. This causes the sliding block 10 in the inner cavity of the mounting cavity 9 to move, causing the spring 12 on the telescopic rod 11 to contract. When the motor housing 4 is placed between the two sets of mounting horizontal plates 5, the rebound force of the spring 12 can push the rollers 13 to reset, thereby limiting and clamping the motor housing 4. This allows the fixture to restrict motor housings of different sizes, enabling economical and efficient rapid switching between production of different models of products. This perfectly meets the needs of flexible production and enhances the company's ability to undertake diversified orders.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
