Description
Technical field
The present invention relates to a kind of clamping device, the clamping device of a kind of easy fractionation spindle support.
Background technology
The spindle support of spindle includes bolster and bolster, and bolster is to be pressed in bolster, in the production process of spindle support, often exists
A certain proportion of defective work, general in the case of, underproof spindle support can be carried out split dismounting, bolster is pulled out from spindle support
Go out, reclaim bolster and other utilizable part of Qi Nei, and only scrap bolster, thus reduce production cost.Existing fractionation
The method of spindle support has two kinds: as it is shown on figure 3, for bolster bearing block containing cone cylindrical spindle support, the method for pulling out of this spindle support
For being fixed on base 8 by right matrix 1 and left matrix 2, the left part of base 8 is motionless, and the right part of base 8 can left and right
Mobile, thus drive right matrix 1 clamp or unclamp bearing block, when clamping bearing block cone excircle part, withstand bolster end with pressure head
Face, bolster stress moves down extracts bolster；As shown in Figure 4, for the spindle support that bearing block is straight cylindrical of bolster, this spindle support
Method for pulling out is to punch with drill bit at the straight cylindrical of bearing block, through the hole of bearing block, plug is placed on base 8 spindle support is unsettled
Slinging, withstand bolster end face with pressure head, bolster stress moves down extracts bolster.Bearing block splits fixture not containing the spindle support of cone cylindrical
It is applicable to the spindle support that bearing block is straight cylindrical split, is because splitting the straight cylindrical of clip not mandrel bearing, fixture base simultaneously
The body production and processing cycle is long, when clamp wear, it is necessary to change whole clip base, causes substantial amounts of waste；And bearing block is
The spindle support of straight cylindrical, currently used method for splitting needs boring, punching rod, and manufacturing procedure is numerous and diverse, and can be only applied to craft
Operation, its production efficiency is low, and labor intensity is big, and the bolster not being suitable for batch is extracted.
Summary of the invention
The invention aims to overcome the above-mentioned weak point of prior art, and a kind of simple in construction, use are provided
The most easily split the clamping device of spindle support.
The technical scheme is that one easily pulls out spindle support clamping device, it includes right matrix, left matrix and chuck, right
Matrix and left matrix are symmetrical arranged and are fixed on hydraulic press base, and chuck includes two symmetrically arranged semi-circular shape chucks
Block, chuck block is respectively symmetrically by bolt and is fixed on right matrix and left matrix, and when two chuck block Guan Bis, it is interior that it is formed
Hole can clamp the bearing block of bolster.
The further technical scheme of the present invention is: described chuck block inner surface axial is provided with multiple radial ringed tooth.
The further technical scheme of the present invention is: described radial ringed tooth cross section is trapezoidal.
The further technical scheme of the present invention is: described radial ringed tooth has axial grooving.
The further technical scheme of the present invention is: described left matrix and base contacts face are provided with bar-shaped trough, bar-shaped trough pair
The base answered is provided with boss, and the size of boss matches with bar-shaped trough, and equipped with spring between boss and bar-shaped trough, left matrix can
Respect thereto horizontal movement, left matrix limits its movement in vertical direction by pressing plate, and pressing plate is connected by bolt with base.
The further technical scheme of the present invention is: described left matrix is provided with vertical holes away from chuck block end, and its end face is opened
Having level trough, level trough passes vertical holes, and it is built with briquetting, and briquetting is provided with in through hole, vertical holes and through hole equipped with axle, briquetting
Expose the end face of left matrix.
The further technical scheme of the present invention is: described right matrix and base contacts face are provided with keyway, keyway built with
Key.
The further technical scheme of the present invention is: described annular tooth is two to four.
The present invention compared with prior art, has a characteristic that
1, being designed with annular tooth due to chuck block clamping part, the trapezoidal shape of teeth portion, thin rear end, front end is thick, it is simple to annular
Dental transition is nipped bearing block cylindrical effectively；Meanwhile, the grooving of annular tooth, it is ensured that annular tooth is as several rows of hard tooth, in pressure
Under power effect, sting mandrel bearing cylindrical securely and do not loosen, can more effectively bolster be extracted from spindle support.
2, due to left matrix away from one end of chuck block equipped with axle and briquetting, it equipped with spring, works as folder with base contacts face
During set block clamp shaft bearing, voussoir can be driven to advance by oil cylinder thus pressurize to briquetting, make left matrix move right, thus press from both sides
Mandrel bearing cylindrical, after extracting bolster, exits oil cylinder, and voussoir retreats, and under spring force, left matrix is return in situ,
Chuck block unclamps, and bolster falls down, and dismantles next time, is suitable for automatization, and during splitting spindle support, base is all motionless
, reduce the energy resource consumption splitting spindle support.
3, use the present invention, thus it is possible to vary the internal diameter of chuck block, be suitable for the bearing block of different sizes, only need to change chuck
Block, it is achieved thereby that the seriation of fixture, it is adaptable to different model bolster.
4, when gripping means grips part wears or when damaging, only need to change chuck block just can, without changing whole folder
Tool, reduces production cost.
