Clamping tool for thin-wall cylindrical parts

Abstract

The invention relates to a clamping tool for thin-wall cylindrical parts. The clamping tool comprises an expansion outer sleeve, an expansion inner sleeve, a locking ring, an expansion body and an elastic sleeve; the expansion outer sleeve is a split cylindrical closing piece; the expansion inner sleeve is a split annular closing piece; an inner cavity of the expansion inner sleeve is a conical surface; guide pins are arranged on the front end surfaces of all components of the expansion inner sleeve; an inner hole of the locking ring is a threaded hole; guide grooves are formed in the back endsurface of the locking ring; the front section of the expansion body is a cylindrical section, and the back section of the expansion body is a conical section; the guide pins of all the components ofthe expansion inner sleeve are inserted in all guide grooves of the locking ring respectively; the front end of the expansion body penetrates through the expansion inner sleeve and the locking ring,and is in threaded connection with a connecting ring of the expansion inner sleeve through an external thread on the back end outer wall of the cylindrical section of the expansion body; the elastic sleeve is fixedly bonded on the inner walls of all the components of the expansion outer sleeve to form the cylindrical closing piece; and the expansion outer sleeve sleeves the expansion inner sleeve.The clamping tool can quickly realize reliable clamping of the thin-wall cylindrical parts.

Description

technical field [0001] The invention relates to a clamping tool for thin-walled cylindrical parts, which belongs to the field of mechanical processing. Background technique [0002] Thin-walled cylindrical parts have poor rigidity, and the parts are prone to elastic deformation during processing and clamping, which seriously affects the processing accuracy of the parts. The current methods mainly include reducing the amount of cutting, increasing the number of semi-finishing operations, and finally finishing to the size requirements. This method is not only time-consuming, but also when the machining allowance is small, the thinner the part, the more difficult it is to process, and it is easy to produce Deformation, resulting in out-of-tolerance part dimensions. Contents of the invention [0003] The object of the present invention is to provide a clamping tool for thin-walled cylindrical parts in order to solve the problems of rigidity, easy deformation and difficult pro...
