Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal workpiece machining clamps, in particular to a hollow metal container machining clamp. BACKGROUND

[0002] Hollow metal containers are often used for filtering, and most of such workpieces are formed by punching on solid blanks to form hollows during machining. The side wall strength of the punched metal part decreases, so during machining, a multi-jaw clamp is used for clamping to increase the contact area of clamping to reduce the extrusion of the workpiece by a single clamping jaw, so as to ensure that the workpiece will not be deformed during clamping. The disadvantage of the multi-jaw clamp is that too many clamping jaws will cover a large area of the workpiece, which will easily block the machining position of the workpiece. Such a clamp is not suitable for clamping workpieces that require full coverage of the side plate during hollow machining. Therefore, this type of clamp needs to be improved. SUMMARY
