Elastic fixture for bellows sleeve

Abstract

The invention relates to mechanical machining fixtures, in particular to an elastic fixture for a bellows sleeve. The elastic fixture for the bellows sleeve comprises a fixture body which is fixedly connected with a workbench. The elastic fixture for the bellows sleeve is characterized in that the fixture body is in the shape of a stepped cylinder, a center stepped through hole is formed in the fixture body in the axial direction, a pull rod is arranged in the fixture body, the pull rod extends out of the through hole of the fixture body, one end of the pull rod is connected with a pressing plate through a locking nut, and the steps of the tail end of the fixture body are sleeved with the bellows sleeve. The elastic fixture for the bellows sleeve has the advantages that the structure is simple, the manufacture and the installation are convenient, the clamping force is small and even, a workpiece is not prone to deformation, the service life is long, and the cutting heat effect in machining is small.

Description

technical field [0001] The invention relates to a machining fixture, in particular to an elastic fixture of a accordion sleeve. Background technique [0002] Various dry cylinder liners are widely used in the machinery industry, and the processing quality requirements of dry cylinder liners are getting higher and higher. Previously, spring sleeve jigs and liquid plastic jigs were used to clamp and process dry cylinder liners. The use of elastic spring sleeves in the process of dry cylinder liner processing has the problem that the manufacturing accuracy is difficult to guarantee, and it is easy to cause the automatic centering accuracy to be difficult to control, thereby affecting the processing quality of the workpiece; the liquid plastic fixture is quite sensitive to cutting heat, and the plastic is easy to Aging, the ratio of plastic components in the manufacturing process is strictly required, although its centering accuracy is high, but there are many shortcomings, it ...

Problems solved by technology

The use of elastic spring sleeves in the process of dry cylinder liner processing has the problem that the manufacturing accuracy is difficult to guarantee, and it is easy to cause the automatic centering accuracy to be difficult to control, thereby affecting the processing quality of the workpiece; the liquid plastic fixture is quite sensitive to cutting heat, and the plastic is easy to Aging, the ratio of plastic components in the manufacturing process is strictly required, although its centering accuracy is high, but there are many shortcomings, it is easy to cause damage to the fixture during use, which in turn affects the processing quality, the wall thickness of the dry cylinder liner is thin, Easy to deform, both of the above two fixtures have the problem of easily deforming the workpiece during use, and the processing quality cannot be guaranteed, which limits the wide use of both in the production of dry cylinder liners
