A Clamping Device for Thin-walled Cylindrical Parts

Abstract

The invention relates to a clamping device for thin-walled cylindrical parts, which belongs to the field of mechanical processing. The clamping tooling of the present invention comprises an expansion sleeve, an expansion inner sleeve, a locking ring, an expansion body and an elastic ring; the expansion sleeve is a split cylindrical structure; the expansion inner sleeve is a tapered inner cavity Cylindrical structure; the inner hole of the locking ring is a threaded hole; the front section of the expansion body is a cylindrical section, the rear section is a tapered section, and the rear end of the cylindrical section is processed with external threads; the expansion sleeve is bonded to the elastic ring inside Closed into a cylindrical assembly, the locking ring and the inner sleeve of the expansion sleeve are put into the inner cavity of the expansion sleeve in turn; the front end of the expansion body passes through the inner sleeve and the locking ring, and passes through the rear end of the cylindrical section of the expansion body The external thread of the outer wall is threadedly connected with the internal hole of the expansion sleeve. The clamping tooling of the present invention has simple structure, convenient processing and simple operation, can quickly realize reliable clamping of thin-walled cylindrical parts, has small clamping deformation, ensures the processing accuracy of products, and improves processing efficiency.

Description

technical field [0001] The invention relates to a clamping device 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 device for thin-walled cylindrical parts in order to solve the problems of rigidity, easy deformation and difficult...
