Further, the tooling components in the processing fixture are fixed by detachable screws.

Compared with the prior art, a milling fixture with a tensioning device that adopts the above technical solution has the following beneficial effects: the outline of the motor cover is positioned and clamped by the fixture, and at the same time, a downward direction is added to the lower end of the motor cover. Tensioning device, the pressure plate of the tensioning device can tighten and loosen the ribs on the bottom surface of the motor cover through the telescopic action of the cylinder. When machining and cutting, a downward tension force is generated, and the motor cover is subjected to cutting force. It is not easy to be displaced when the motor cover is not easy to be displaced, so as to ensure the accuracy of the motor cover and improve the processing efficiency.
