Universal flexible clamp for thin-walled parts

Abstract

A universal flexible clamp for thin-walled parts is mainly composed of a right pressing disc, an axial spring, a supporting ring, an ejection rod, a spring, a supporting fan, a screw, a nut, a spacerring, an ejection ring, a right pressing disc, an adjusting washer, a rotary nut, a supporting shaft and the like. An internal thread is machined on a center hole of the right pressing disc. An external thread is machined at the right end of the supporting shaft, and the right end of the supporting shaft is fixedly connected with the right pressing disc in a threaded mode. The left end of the supporting shaft is sleeved with the left pressing disc. The adjusting washer is mounted between the nut and the left pressing disc. Two radial supporting mechanisms are arranged on the supporting shaft in the axial direction, located between the supporting shaft and the left pressing disc and mainly composed of an internal stop nut, a T-shaped connection groove, a supporting piece, a screw cap, a nut, an upward-pulling spring hanger, a supporting spring, a downward-pulling spring hanger, a groove and the like. The universal flexible clamp is simple in structure and low in production cost, clamping deformation of the parts is reduced, and the production efficiency and quality stability of the thin-walled parts are improved.

Description

Technical field [0001] The invention relates to the technical field of clamps, in particular to a flexible clamp for general thin-walled parts. Background technique [0002] Metal thin-walled parts have the advantages of light weight, small footprint, compact structure, and material saving, so many mechanical products have such parts. There are many ways to manufacture such parts, such as: stamping with sheet metal, roll welding, explosive forming, etc., but turning is the most commonly used method. Because of the thin wall, radial dimension and axial dimension of this kind of parts, the difference is dozens or even hundreds of times, so the rigidity of the workpiece is relatively weak, which brings great difficulties to turning and clamping. When the workpiece is improperly clamped, it will be deformed. For example, using a normal three-jaw chuck to clamp the workpiece will cause deformation of the aperture of the workpiece; using the three-jaw chuck to tighten the inner hole w...

Problems solved by technology

Other methods are also used, such as liquid plastic tensioning or spring clip tensioning, but these clamping methods all affect the processing accuracy of the parts, mainly because the deformation of the parts is inevitable during the clamping process, so that the resulting Increased scrap, resulting in increased processing costs
