Abstract

The invention relates to a clamping device for elastic material radial milling. The clamping device for elastic material radial milling comprises a base body, square plates, pin bolts, a cover plate and nuts, wherein the radial positioning surface of the base body and an inner hole of a part are in interference fit. A numerical control vertical type processing center with a numerical control dividing head is adopted; the base body is mounted on a working table of the numerical control dividing head; the axis of the base body is aligned to be coaxial with the axis of the numerical control dividing head; a part to be processed is mounted on the radial positioning surface of the base body; the part to be processed is fixed by tightly screwing the nut through a suitable force of a torque wrench; square holes of the part are firstly processed into round holes, then each pin bolt is respectively arranged in every each round hole, and the round holes without the pin bolts are processed into square holes to finish the first processing step; the square plates are respectively arranged in the finished square holes, the pin bolts are disassembled, and finally the round holes are processed into square holes to finish the second processing step. The clamping device for elastic material radial milling is low in clamping deformation, reliable in performances and convenient to assemble and disassemble, improves milling efficiency, and is suitable for radial milling of the elastic materials which are difficult in clamping and produced in batches.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a clamping device for radial milling of elastic materials. Background technique [0002] Porous polyimide is used as a polymer special engineering material. It can be used not only as a structural part of the bearing, but also as a lubricating part of the bearing, so it is widely used in the gyro bearing cage of navigation instruments in aerospace, precision machinery and other fields. However, its relatively low mechanical strength, difficult clamping, and large elastic deformation lead to the unstable state of porous polyimide during milling, and it is difficult to guarantee the dimensional accuracy and shape accuracy after milling. Contents of the invention [0003] The purpose of the present invention is to provide a clamping device for radial milling of elastic materials, aiming at difficulties such as difficult clamping of parts, large processin...
