Technical Field
[0001] This utility model relates to the field of motor end cover processing technology, specifically a clamping fixture for processing high-efficiency permanent magnet precision motor end covers. Background Technology
[0002] The machining of motor end caps requires high precision, such as the accuracy of the mounting hole position and flatness. During machining, the cutting force can cause the end cap to shift or vibrate. Using clamping fixtures to fix it can reduce displacement and vibration, and ensure dimensional and shape accuracy. The machining process of precision motor end caps is complex. In operations such as turning, milling, and drilling, clamping fixtures can provide a stable machining environment.
[0003] The prior art discloses a clamping fixture for machining motor end caps, application number 202410805406.0, including a machine tool worktable, a third rotating shaft rotatably mounted on the machine tool worktable, a cutter head fixedly mounted on the third rotating shaft; several connecting sleeves are mounted on the cutter head, and a third motor is fixedly mounted in each connecting sleeve; the output shaft of the third motor is driven to connect to a grinding cylinder, and a drill bit is fixedly mounted at the end of the grinding cylinder away from the third motor, the drill bit being used to drill holes in the motor end cap; a grinding rod is mounted on the grinding cylinder; a posture changing component is provided inside the grinding cylinder, the posture changing component being connected to both the grinding rod and cooperating with the motor end cap, so as to drive the grinding rod to change posture; the grinding rod is used to grind the inner surface of the drilled hole in the motor end cap and the surface of the motor end cap.

However, when clamping the end cap, it is not convenient to adjust the end cap. Moreover, since it uses a side clamping method, it is necessary to re-fix it when processing the side of the end cap, which is quite troublesome. Utility Model Content
