The connecting plate 14 is fixedly installed on the bottom fixed cylinder 1.

[0029] A guide rod 23 is fixedly installed on the connecting plate 14 and is arranged parallel to the lead screw 13. The guide rod 23 is slidably connected to the moving block 12.

[0030] The bottom surface of the bottom fixing cylinder 1 is set as an inclined surface. A waste collection port 15 is set on the outside of the bottom fixing cylinder 1 at the lower part of the inclined surface. A door panel 16 is hinged on the waste collection port 15.

[0031] A cylinder 17 is fixedly installed on the bottom inner side of the bottom fixed cylinder 1. A lifting rod 18 is fixedly connected to the upper hydraulic rod of the cylinder 17. A lifting support plate 19 is fixedly installed at the upper end of the lifting rod 18. There is a certain gap between the lifting support plate 19 and the inner wall of the bottom fixed cylinder 1.

[0032] A guide sleeve 20 is slidably provided on the outer side of the lifting rod 18, and the guide sleeve 20 is fixedly connected to the inner wall of the bottom fixed cylinder 1 by the bracket 21.

[0033] There are three sets of inclined groove 3, sliding rod 4, sliding block 5, clamping block 6, clamping pad 7 and bending frame 8. The inner sides of clamping block 6 and clamping pad 7 are both arc-shaped, and clamping pad 7 is a rubber pad.

[0034] The bottom fixing cylinder 1 of this utility model is the basic support component of the entire fixture. It is made of high-strength alloy material to ensure stability and durability. Its upper end is designed to be open for easy installation and operation, and also facilitates fixing the end of the motor housing. The lower end of the bottom fixing cylinder 1 is closed, and the interior is equipped with reinforcing ribs to improve structural strength. The inner bottom surface is set as an inclined surface, which allows the debris generated during processing to naturally slide to the waste collection port, reducing cleaning difficulty. The rotating disk 2 is installed on the upper end of the bottom fixing cylinder 1 and rotates smoothly through precision bearings. Three inclined grooves 3 are evenly distributed on the rotating disk 2 to accommodate the inclined movement of the sliding rod 4. The design of the inclined grooves 3 allows the sliding rod 4 to move obliquely when the rotating disk 2 rotates, thereby driving the clamping block 6 to open and close, which is suitable for motor housings of different sizes. The sliding rod 4 is embedded in the inclined groove 3, and the precise sliding fit ensures stable movement. The sliding block 5 is fixed to the top of the sliding rod 4.

The handle 9 is fixed to one side of the rotating disk 2, and the slide groove 10 is opened along the axial direction of the handle, allowing the slide rod 11 to slide freely within the slide groove 10. The moving block 12 is connected to the slide rod 11 and to the connecting plate 14 via the lead screw 13, enabling precise position adjustment. Rotating the handle 22 drives the lead screw 13 to rotate. Due to the threaded engagement between the lead screw 13 and the moving block 12, the rotating disk 2 can be adjusted, ensuring precise locking of the rotating disk 2 in different positions. The guide rod 16 is set parallel to the lead screw 13 to ensure the stability of the moving block 12 during movement. The cylinder 17 is installed at the bottom inside the bottom fixed cylinder 1 and is connected to the lifting support plate 19 via the lifting rod 18. The cylinder 17 drives the lifting support plate 19 to move up and down, providing a stable support platform for the motor housing and controlling the height of the motor housing. At the same time, the guide sleeve 20 on the outside of the lifting rod 18 combines with the bracket 21 to ensure smooth and precise lifting.

[0035] The specific working process of this utility model is as follows:

[0036] Preparation stage: Place the motor housing on the lifting platform 19 and adjust the cylinder 17 to raise the lifting platform to the appropriate position.

[0037] Clamping operation: Rotate the handle 9 to guide the sliding rod 4 and sliding block 5 to move towards the center through the inclined groove 3, and the clamping block 6 and clamping pad 7 gradually clamp the motor housing.

[0038] Fine-tuning and locking: Rotate handle 15, and through the threaded engagement of lead screw 13 and moving block 12, fine-tune the position of rotating disk 2 to ensure stable clamping and then lock it.

[0039] Processing procedure: Start the processing equipment to perform end processing on the motor housing. During processing, cylinder 17 keeps the lifting support plate stable to prevent vibration from affecting processing accuracy.

[0040] Waste collection: After processing is completed, cylinder 17 is closed, the lifting pallet descends, the motor housing falls down, and the processing debris slides down the inclined surface to the waste collection port. The door panel 16 is then opened for cleaning.

[0041] Release the clamp: Rotate the handle 9 in the opposite direction, the sliding rod 4 and the sliding block 5 move outward, the clamp 6 releases the motor housing, and one processing cycle is completed.

[0042] Through the above design, this fixture not only improves the machining accuracy and efficiency of the motor housing end, but also significantly simplifies the operation process and reduces the difficulty of operation, which is a technological innovation in the field of motor manufacturing.
