Abstract
The invention discloses a three-valve separated expander, and relates to the technical field of machining of mining ground tackle clamping piece products. The three-valve separated expander comprises a shaft (1), and is characterized in that one end of the shaft (1) is of a three-valve separated structure; each valve is sleeved by an expansion core (2); the expansion cores (2) are sleeved by expansion sleeves (3); and the other end of the shaft (1) is a taper thimble. The three-valve separated structure is in central symmetry about the shaft (1); and each valve is the same in size. The three-valve separated expander is low in manufacturing cost, a workpiece is very convenient to mount and take out, a machine tool absolutely can perform automatic clamping and loosening work, thereby reducing the labor intensity of workers to a relatively large extent.
Description
Technical field
The present invention relates to mining anchorage device intermediate plate series products processing technique field, be specifically related to a kind of three lobe separate type expanders.
Background technology
The outer conical surface processing of mining anchorage device intermediate plate typically uses lathe process, traditional workpiece clamping mechanism to use: intermediate plate one end end face axle positions, and other end tailstock tapering thimble pushes enforcement Workpiece clamping.In the course of processing, as bigger than normal in work pieces process surplus, workpiece bears cutting force increase meeting, and product endoporus is relative with clamp system to skid, molding cutter well damage, and processing workpiece is likely scrapped.Additionally common expander uses one end and is divided axially into the three lobe other ends and design for integral type, if long-time use easily causes root metal fatigue and rupture.
Summary of the invention
It is an object of the present invention to provide a kind of three lobe separate type expanders, it has low cost of manufacture, workpiece is being installed, taken out very convenient, and lathe can be implemented Automatic-clamping completely, unclamp work, reduces the features such as artificial labor intensity largely.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it includes axle 1, it is characterised in that: one end of described axle 1 is three lobe separate type structures, and every lobe is cased with the core 2 that rises, being cased with ringfeder 3 outside the described core 2 that rises, the other end of axle 1 is tapering thimble.Described three lobe separate type structures are about axle 1 centrosymmetry, and every lobe size is identical.Low cost of manufacture of the present invention, workpiece are being installed, are being taken out very convenient, and lathe can be implemented Automatic-clamping completely, unclamp work, reduces artificial labor intensity largely.
The present invention has a following usefulness:
1, three lobe separate type tension mechanisms use and workpiece two ends are implemented clamping simultaneously, thoroughly solve skidding that workpiece causes present in the Vehicle Processing process because of insufficient clamping force, cutter collapses broken situation.
2, three lobe separate type tension mechanism one end use three lobe separation taper shafts, workpiece install, take out very convenient fast, lathe can be implemented Automatic-clamping completely, unclamp work, reduces the labor intensity of workman largely.
3, achieving workpiece automatization clamping function due to three lobe separate type tension mechanisms, production unit efficiency is greatly improved, and the semi-manufactured goods quality produced is stable.
4, three lobes are kept completely separate, the problem that there is not fracture, make be greatly increased service life, have saved cost.
5, when workpiece is inserted in tension shaft, tailstock tool thimble is by pneumatic system quickly push-tight automatically, it is achieved that the clamping fast and automatically to workpiece.
Accompanying drawing illustrates:
Fig. 1 is the horizontal sectional drawing of the present invention three lobe separate type expander；
Fig. 2 tri-lobe separate type structural vertical profile.
Detailed description of the invention
With reference to Fig. 1-2, it includes axle 1, it is characterised in that: one end of described axle 1 is three lobe separate type structures, and every lobe is cased with the core 2 that rises, described in rise and be cased with ringfeder 3 outside core 2, the other end of axle 1 is tapering thimble.Described three lobe separate type structures are about axle 1 centrosymmetry, and every lobe size is identical.
Low cost of manufacture of the present invention, workpiece are being installed, are being taken out very convenient, and lathe can be implemented Automatic-clamping completely, unclamp work, reduces artificial labor intensity largely.Location, its one end, tensioner, other end tailstock tapering thimble holds out against, and implements clamping at workpiece two ends simultaneously.And three lobes are to be kept completely separate the problem that there is not fracture.Thus thoroughly solve the problem of the tradition all existence of expander clamp system, and operative gets up the most smoothly, fast.
Claims (2)
1. three lobe separate type expander, including axle (1), it is characterized in that: one end of described axle (1) is three lobe separate type structures, it is cased with, on every lobe, the core (2) that rises, being cased with ringfeder (3) outside the described core that rises (2), the other end of axle (1) is tapering thimble.
Three lobe separate type expanders the most according to claim 1, described three lobe separate type structures are about axle (1) centrosymmetry, and every lobe size is identical.
