Anti-deviation clamp for steel seal

The anti-deviation clamp for the steel seal comprises a steel seal machine main body and an installation column main body, a supporting disc is fixedly installed on the outer surface of the installation column main body, an installation assembly is detachably installed on the outer surface of the installation column main body, and a clamp assembly is fixedly installed on the top face of the installation assembly. According to the scheme, one end of the cylindrical workpiece is placed in the chuck device to be clamped and fixed, then the second rotary knob is rotated till the other end of the cylindrical workpiece is supported by the supporting plate, then steel seal machining is conducted on the workpiece, and when multiple positions of the surface of the workpiece need to be subjected to steel seal machining, the chuck device can be driven by the driving device to rotate; by means of the structure, the workpiece can be horizontally and transversely placed and stably positioned, so that the requirement for st
