Abstract
The invention discloses a three-valve separated expander and relates to the technical field of mineral anchorage clamping piece type 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, an expanding core (2) sleeves each valve, an expanding sleeve (3) sleeves each expanding core (2), and a taper center is arranged at the other end of the shaft (1). The three-valve separated structure is in central symmetry relative to the shaft (1), and the valves are same in size. The three-valve separated expander is low in manufacturing cost, facilitates workpiece mounting and taking out, enables machine tools to completely execute automatic clamping and releasing actions, and greatly reduces the labor intensity of manpower.
Description
art 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 generally adopts lathe process, and traditional workpiece clamping mechanism adopts: intermediate plate one end end face axle is located, and other end tailstock tapering thimble pushes enforcement Workpiece clamping.In process, 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, and molding cutter well damage, processing work is likely scrapped.What common expander adopted in addition is one end is axially the divided into three lobe other ends designs, if long-time use easily causes root metal fatigue and ruptures for integral type.
Summary of the invention
The object of the invention is to provide a kind of three lobe separate type expanders, its have low cost of manufacture, workpiece in installation, take out very convenient, lathe can be implemented Automatic-clamping completely, unclamp work, reduces the features such as artificial labour intensity largely.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises axle (1), it is characterized in that: one end of described axle (1) is three lobe separate type, on every lobe, cover has the core that rises (2), the described core that rises (2) overcoat has ringfeder (3), and the other end of axle (1) is tapering thimble.Described three lobe separate type are about axle (1) Central Symmetry, and every lobe size is identical.Low cost of manufacture of the present invention, workpiece in installation, take out very convenient, lathe can be implemented Automatic-clamping completely, unclamp work, reduces artificial labour intensity largely.
The present invention has following usefulness:
1, three lobe separate type tension mechanisms adopt and implement clamping to workpiece two ends simultaneously, thoroughly solve the skidding caused because of insufficient clamping force that workpiece exists in Vehicle Processing process, cutter collapses broken situation.
2, three lobe separate type tension mechanism one end adopt three lobes to be separated taper shafts, workpiece in installation, take out fast very convenient, lathe can be implemented Automatic-clamping completely, unclamp work, reduces the labour intensity of workman largely.
3, because three lobe separate type tension mechanisms achieve workpiece automation clamping function, production unit efficiency is greatly improved, and the semi-manufactured goods quality produced is stablized.
4, three lobes are separated completely, there is not the problem of fracture, and service life is increased greatly, have saved cost.
5, when workpiece is inserted in tension shaft, tailstock tool thimble, by pneumatic system push-tight fast automatically, achieves 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 sectional elevation figure.
Detailed description of the invention
With reference to Fig. 1-2, it comprises axle (1), it is characterized in that: one end of described axle (1) is three lobe separate type, on every lobe, cover has the core that rises (2), the described core that rises (2) overcoat has ringfeder (3), and the other end of axle (1) is tapering thimble.Described three lobe separate type are about axle (1) Central Symmetry, and every lobe size is identical.
Low cost of manufacture of the present invention, workpiece in installation, take out very convenient, lathe can be implemented Automatic-clamping completely, unclamp work, reduces artificial labour 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 be separated the problem that there is not fracture completely.Thus thoroughly solve all Problems existing of traditional expander clamp system, and operative gets up very smoothly, fast.
Claims (2)
1. a lobe separate type expander, comprise axle (1), it is characterized in that: one end of described axle (1) is three lobe separate type, on every lobe, cover has the core that rises (2), the described core that rises (2) overcoat has ringfeder (3), and the other end of axle (1) is tapering thimble.
2. three lobe separate type expanders according to claim 1, described three lobe separate type are about axle (1) Central Symmetry, and every lobe size is identical.
