Automatic flange manufacturing device

The invention discloses an automatic flange manufacturing device which comprises a grinding frame and further comprises a clamping mechanism used for clamping a flange and a grinding mechanism, the grinding mechanism comprises a grinding shaft capable of being driven to rotate, the grinding shaft is used for being inserted into a bolt hole of the flange, a plurality of grinding plates are rotationally arranged on the grinding shaft, and when the grinding shaft rotates, the grinding plates are driven to rotate. According to the automatic flange manufacturing device, the grinding plates extending into the bolt holes of the flange can be thrown out under the rotating centrifugal effect so that the grinding plates can be attached to the inner walls of the bolt holes of the flange to conduct rotating grinding, the grinding effect is good, and the automatic flange manufacturing device can adapt to flange holes of different sizes; the operation is convenient. 本发明公开了一种自动法兰制造装置，包括打磨架，还包括夹持机构，其用于夹持法兰，打磨机构，其包括受驱动能够旋转的打磨
