Abstract

The invention relates to a clamping device, in particular to a rotary inner clamping device. The device comprises a cylindrical clamp main body, wherein a ring of uniformly distributed clamping jaws are hinged at the circumference of the clamp main body; the clamping jaws radially rotate along the clamp main body; a driven end of each of the clamping jaws is used for clamping inner holes of a clamping workpiece, and a driving end of the clamping jaw is butted against the lower edge of a cam ring sleeved on the clamp main body; the upper edge of the cam ring is horizontally and slidingly matched with a convex ring arranged on the clamp main body; cams butted against the driving end of the clamping jaw are arranged at the lower edge of the cam ring; and a hole for inserting a handle is formed at the outer edge of the cam ring. By adopting the technical scheme, the rotary inner clamping device is simple in structure, convenient to operate and low in cost.

Description

technical field [0001] The invention relates to a clamping device, in particular to an inner clamping device. Background technique [0002] Generally, during machining, the workpieces to be processed must be fixed, and the clamping device plays a vital role in machining. [0003] Although all kinds of clamping devices can meet the requirements of workpiece clamping to a certain extent, because they are non-standard devices, they often need to be designed and manufactured according to product mechanism characteristics, production conditions and actual needs, and may not be suitable for other clamping devices. Therefore, the development of clamping devices cannot be slack. In addition, many clamping devices now have problems such as complex structure, difficult operation, high requirements for operators, complex devices, and high cost. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a clamping device with simple s...
