[0002] Using a rotary clamp to weld steel pipes is a common method in mechanical equipment manufacturing. The existing rotary clamp may not be able to keep the workpiece rotating smoothly and at a uniform speed due to the floating size of the workpiece, which in turn affects the quality of the workpiece. Therefore, how to properly clamp the workpiece so that it always rotates with a high degree of coaxiality is a key consideration.
