Centering and clamping device for stepped sleeve

Abstract

The invention provides a centering and clamping device for a stepped sleeve, and belongs to the technical field of machining. The centering and clamping device comprises a slide bar and a wedge post, wherein the slide bar is arranged on a slide bar sliding chute of a supporting shaft seat in an upward / downward sliding way through a guide segment; an anti-rotation pin shaft is inserted into an anti-rotation guide groove; upper centering and clamping blocks are arranged on upper centering grooves of the supporting shaft seat in a radial sliding way; the inner sides of the upper centering and clamping blocks fit upper conical rings on centering segments of the slide bar; upper garter springs are arranged on the three upper centering and clamping blocks in an encircling way; lower centering and clamping blocks are arranged on lower centering grooves of the supporting shaft seat in a radial sliding way; the inner sides of the lower centering and clamping blocks fit lower conical rings on the centering segments of the slide bar; lower garter springs are arranged on the three lower centering and clamping blocks in an encircling way; the wedge post is arranged on a guide sliding sleeve in a leftward / rightward sliding way; a V-shaped wedge block is arranged at the left end of the wedge post; a cam fits a support roller. By adopting the centering and clamping device, centering and clamping of the stepped sleeve are realized rapidly, and the stepped sleeve is convenient for charging and discharging.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a centering clamping device for a stepped sleeve. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. The machinery required for processing consists of digital display milling machine, digital display forming grinder, digital display lathe, EDM machine, universal grinding machine, machining center, drilling machine, laser welding, fast wire walking, medium wire walking, slow wire walking, outer cylindrical grinder, inner circle Grinding machines, precision lathes, etc. Cutting processing refers to the processing method of using cutting tools (including cutting tools, grinding tools and abrasives) to cut off the excess material layer on the blank or workpiece into chips, s...
