[0002] A flange usually refers to a disk-like metal body with several holes for fixing around it, and the holes can connect the flange to other things. Flanges can be divided into integral flanges, slip-on flanges and threaded flanges according to their structural types. Common integral flanges include flat welding flanges and flanges.

[0003] When drilling a flange, the flange needs to be clamped and fixed. The existing clamp has a poor clamping effect on the flange and cannot well complete the clamping and fixing operation of the notched flange. During processing, the position of the flange needs to be adjusted manually, which reduces the processing efficiency and increases the labor cost.

[0008] In the above-mentioned flange clamping device, the lifting seat is fixedly arranged on the upper end of the driving gear and rotates with the rotation of the driving gear. The lifting seat and the connecting seat are connected by four connecting rods, and the connecting rods are driven to rise and fall by the driving cylinder, thereby driving the connecting seat to rise and fall.
