The reduction of working medium amount.For external-expanding type fixture by rising outside collet to clamp workpiece, the common outer fixture that rises, elastic collet is installed on lathe
After upper, to carry out according to clamped product aperture come workpiece machining clamp, to ensure the diameter of collet and concentricity.Once fixture
After being removed, being reinstalled can cause concentricity unqualified and can not use.
The content of the invention
In view of the deficiencies of the prior art and defect, there is provided rise fixture outside a kind of fast disassembly type, has fast, concentricity of replacing speed
The advantages of good, and it is reusable after fixture dismounting.
To achieve the above object, the utility model provides following technical scheme.
Rise fixture outside a kind of fast disassembly type, includes flange, elastic collet, pull rod and driving mechanism, flange and machine tool chief axis
It is fixedly connected, elastic collet is arranged on flange, and pull rod is through elastic collet and flanged joint in also being set in driving mechanism, flange
There is the adjustment block coordinated with elastic collet, adjustment block is fixedly connected in flange by the first screw, is additionally provided with and adjusts on flange
The adjusting screw that monoblock coordinates, is additionally provided with end face positioning anchor outside flange, end face positioning anchor and elastic collet closely offset with
Elastic collet is fixed on flange, end face positioning anchor is fixedly connected in adjustment block by the second screw.
Further, driving mechanism is hydraulic connecting bar.
Further, adjustment block and the matched face of elastic collet are the conical surface.
Further, the first screw, the second screw and adjusting screw are hexagon socket head cap screw.
Further, flange is equipped with radially installed hole, and adjusting screw offsets through mounting hole with adjustment block.
Further, pull rod and the matched face of elastic collet are the conical surface.
The beneficial effects of the utility model are：Rise outside a kind of fast disassembly type fixture, include flange, elastic collet, pull rod and
Driving mechanism, flange are fixedly connected with machine tool chief axis, and elastic collet is arranged on flange, and pull rod connects through elastic collet and flange
Driving mechanism is connected to, the adjustment block coordinated with elastic collet is additionally provided with flange, adjustment block is fixedly connected on by the first screw
The adjusting screw coordinated with adjustment block is additionally provided with flange, on flange, end face positioning anchor is additionally provided with outside flange, end face positioning is leaned on
Mountain closely offsets so that elastic collet is fixed on flange with elastic collet, and end face positioning anchor is fixedly connected by the second screw
In in adjustment block.When the utility model is used, pull rod is pushed to right end by driving mechanism, at this time pull rod top and elastic collet point
From elastic collet is not in spreading state at this time, and the outside diameter of elastic collet is less than the internal diameter of workpiece, workpiece can be sheathed on elasticity
On collet, the pre- clamping work of workpiece is completed, driving mechanism is then operated and pulls pull rod to the left, pull rod top and elastic collet
It is engaged by elastic collet spreading, so that the workpiece being sheathed on elastic collet be fixed, to complete the clamping to workpiece.Work as dress
When pressing from both sides different workpiece, different elastic collets is used, at this time, by unscrewing the second screw, can use lower face positioning anchor,
And then elastic collet, the elastic collet more renewed are taken out, then be fixed by end face positioning anchor, replace elastic collet
Afterwards, due to by the way of adjustment block and elastic collet cone match, being effectively guaranteed the concentricity of elastic collet, have more
The advantages of throw-over degree is fast, and concentricity is good, and it is reusable after fixture dismounting.
