Abstract

The invention discloses a dual-purpose clamping device for internally supporting and externally clamping. The dual-purpose clamping device comprises three clamping assemblies which are uniformly distributed at an interval of 120 degrees, each clamping assembly is of a structure formed by shoulder portions and a convex portion with the cross section being of an inverted T shape, screw holes are formed at the should portions on the two sides, and an annular clamping slot is formed on the bottom face; internally-supporting concave platforms are formed on the outer side walls of the convex portions, externally-clamping concave platforms are formed on the inner side walls of the of the convex portions, and raised lines are formed on the externally-clamping concave platforms; and the side walls of the internally-supporting concave platforms and the side walls of the externally-clamping concave platforms are all externally-protruded circular-arc faces. By means of the dual-purpose clamping device, the problems that a clamping device is changed frequently due to change of a workpiece clamping manner, much time is consumed, and machining efficiency is low are effectively solved, and the small-batch machining requirement of a scientific research task can be met.

Description

technical field [0001] The invention belongs to a clamping device, in particular to a dual-purpose clamping device for inner support and outer clamping. Background technique [0002] There are many scientific research tasks. When processing workpieces, sometimes it is necessary to use the inner support clamping device, and sometimes it is necessary to use the outer clamping device. This requires frequent replacement of the clamping device, which is time-consuming and low in processing efficiency. Therefore, how to reduce the number of times to replace the clamping device and improve the processing efficiency of the workpiece is the key to the problem. Contents of the invention [0003] The present invention is proposed in order to overcome the shortcomings of many clamping device replacements and low processing efficiency in the prior art in workpiece turning, and its purpose is to provide a dual-purpose clamping device for internal support and external clamping.
