Abstract
The invention relates to a self-centering retainer elastic clamping fixture and belongs to the field of designs of bearing retainer tools. The self-centering retainer elastic clamping fixture consists of a main body, wherein the main body is connected to a machine tool through bolts; and a pull rod is arranged in the middle of the main body and is connected to a boring machine. The self-centering retainer elastic clamping fixture is a stepped multi-layer clamping fixture having multiple clamping diameter structures, and consists of a first dimension section, a second dimension section, a third dimension section and a spring transition bush, wherein the main body and the spring transition bush are made of 65 MN spring steel. The self-centering retainer elastic clamping fixture has the advantages of low cost, simple operation, convenience in clamping, high efficiency and improvement of the boring quality of a bearing retainer.
Description
Technical field
The present invention relates to a kind of self-centering retainer elasticity mold, belong to retainer frock design field.
Background technology
Serial copper cages such as thin spheric roller bearing retainer, taper roll bearing retainer, centripetal thrust force roller bearing retainer, because wall is thin, when the processing bore hole, can't normally be installed, with normal bore hole mold, can produce machining deformation, not reach the product standard requirement.Along with increasing of this product, this contradiction is also more and more, and this also is the difficult problem in the industry, can't be well solved all the time.
Summary of the inventionIn view of the defective that prior art exists, the purpose of this invention is to provide that a kind of cost is low, simple to operate, the self-centering retainer elasticity mold of convenience that be installed, efficient height, raising retainer bore hole quality.
For achieving the above object, the technology used in the present invention solution mainly is: a kind of self-centering retainer elasticity mold, constitute by main body, and main body is connected on the lathe by bolt, is provided with pull bar in the middle of main body, and pull bar is connected on the boring machine.
Described a kind of self-centering retainer elasticity mold is a multilayer clamp body with band ladder of many clampings diameter structure, is made up of first size section, second size section, the 3rd size section and spring reducing bushing.
Described main body and spring reducing bushing are to be made by the 65MN spring steel.
A kind of self-centering retainer elasticity mold, its beneficial effect is: it is a kind of general jig of making of spring steel, strain by material, the automatic clamping force that produces, retainer that will bore hole evenly clamps automatically, and self-centering retainer elasticity mold is a multilayer clamp body with band ladder of many clampings diameter structure, is respectively equipped with first size section, second size section, the 3rd size section, is an extraordinary mold of versatility.The invention of especially this mold has also solved the bad problem of axiality of the bore hole of original bore hole retainer mold existence.Axiality originally preferably can reach 0.2 millimeter, can reach 0.05 millimeter now, improves 4 times of precision.In addition when changing workpiece, operate very simply, increase work efficiency, contrast generally the mold technology increase work efficiency 5 times.Can be applied to multiple retainers such as spherical bearing retainer, thrust conical bearing retainer, thrust ball bearing retainer.
Description of drawings
Fig. 1 is a kind of structure diagram of self-centering retainer elasticity mold.
Fig. 1 Reference numeral is as follows: 1, main body, 2, the spring reducing bushing, 3 bolts, 4, pull bar.
The specific embodiment
In the structure diagram of a kind of self-centering retainer elasticity mold shown in Figure 1, its primary structure comprises: be made of main body 1, main body 1 is connected on the lathe by bolt 3, is provided with pull bar 4 in the middle of main body 1, and pull bar 4 is connected on the boring machine.
Described a kind of self-centering retainer elasticity mold is a multilayer clamp body with band ladder of many clampings diameter structure, is made up of first size section, second size section, the 3rd size section and spring reducing bushing 2.
Described main body 1 and spring reducing bushing 2 are to be made by the 65MN spring steel.
A kind of self-centering retainer elasticity mold, its operation principle is:
Self-centering retainer elasticity mold, main body 1 is connected on the lathe by bolt 3, pull bar 4 is connected on the boring machine, in the middle of the main body 1 tie rod hole is arranged, when pull bar 4 spurs inwards, the mold of making of spring steel directly is connected on the boring machine owing to the small end external diameter, big end will produce very big convergent force tension pull bar, is exactly clamping work pieces, begins workpiece is carried out bore hole, releasing lever 4 unclamps workpiece holding frame exactly.This is a kind of general jig of making of spring steel, and principle is the strain by material, the automatic clamping force of generation, and retainer that will bore hole evenly clamps automatically.
