Self-centering rapid taking, placing and clamping device for shaft sleeve part with inner curved surface

Abstract

The invention provides a self-centering rapid taking, placing and clamping device for a shaft sleeve part with an inner curved surface. The self-centering rapid taking, placing and clamping device comprises a mandrel, a transmission taper sleeve, a fixing body and a pushing sleeve. The rear section of the mandrel is sleeved with the transmission taper sleeve in a front-back sliding mode, the front end of the mandrel is fixedly sleeved with the fixing body, and the rear end of the mandrel is sleeved with the pushing sleeve in a front-back sliding mode. The front end of the transmission taper sleeve is connected with the rear end of the fixing body through a small spring, and the rear end of the transmission taper sleeve is connected with the rear end of an inner cavity of the pushing sleeve through a large spring. The self-centering rapid taking, placing and clamping device has the advantages of being high in precision, convenient to use, reliable in operation and rapid in taking and placing, irregular curved surfaces on the inner cylindrical surfaces of shaft sleeve parts can be automatically aligned, clamped and positioned, the clamping and positioning problems of the parts are effectively solved, the production efficiency is improved, the production cost and the labor intensity are reduced, and the machining requirements of the parts are met.

Description

technical field [0001] The invention relates to the technical field of clamping of shaft sleeve parts, in particular to a self-centering fast pick-and-place clamping device for inner curved shaft sleeve parts. Background technique [0002] During the processing of bushing parts, especially the bushing parts whose inner cylindrical surface contains irregular curved surface, the usual processing technology is to process the outer surface of the part first, and then clamp the outer surface of the part to process the inner surface of the part. However, when the outer surface of this type of bushing parts has features such as bosses and shoulders, it is difficult to clamp the outer surface of the parts. Moreover, the final finishing process of the outer surface of many bushing parts requires grinding , which means that the inner surface of the part must be clamped to complete the final machining of the part. Therefore, for the shaft sleeve parts with irregular curved inner cylin...
