Plate etc., is required for taking a long time and carries out workpiece benchmark centering and adjustment before processing every time, the lathe secondary process time compared with
Long, production efficiency is relatively low, therefore such fixture is relatively adapted to the digital control processing of single-piece and parts in small batch.For high-volume bottom surface
With the digital control processing that side benchmark is planar part, usual bottom surface is positioned using support nail or positioning plane, utilizes magnetic force
Base or vacuum cup are tensed；And side is positioned using supporting plate or support nail, directly it is fixedly clamped using screw.
Although aforesaid way can complete locating clip clamping of workpieces quickly, using screw be directly fixedly clamped workpiece when, thrust is excessive
Workpiece deformation and position error increase may be caused, when workpiece adjustment will also increase lathe secondary process during simultaneously clamping on
Between.
The content of the invention
In order to overcome cause workpiece deformation during existing numerical control clamp locating clip clamping of workpieces, position error is larger and lathe auxiliary
The problem of process time is longer, the utility model provide one kind and are used for Digit Control Machine Tool fluting elastomer block fixture, and the fixture can not only
Fast positioning clamping fixes workpiece, and can reduce workpiece deformation and position error in clamping process, so as to improve adding for part
Work precision and processing efficiency.
Technical scheme is used by the utility model solves its technical problem：It is described to be used for Digit Control Machine Tool fluting elastomer block
Compressing fixture is by chuck body, bottom supporting nail and vacuum suction component, short side side supporting plate and fluting elastomer block, long side branch
Fagging and fluting elastomer block composition.There are three positioning holes in the chuck body bottom surface, and three support nails are installed respectively, be used for
Workpiece sole plane positions；There is a through hole in chuck body bottom center, thereon equipped with vacuum suction component, for workpiece base
Face is tensed；Supporting plate is respectively provided with two adjacent sides of chuck body, the positioning for workpiece side basal plane；In workpiece two
Side base, equipped with fluting elastomer block, is positioned to the fluting elastomer block using two straight pins, is used in combination in the chuck body on side
Two screws are fixed to chuck body, and for being compressed to workpiece side basal plane, wherein workpiece long side is equipped with two flutings
Elastomer block, workpiece short brink is equipped with a fluting elastomer block.It is described be used for Digit Control Machine Tool fluting elastomer block compressing fixture in use,
First have to workpiece being placed on three support nails；Next allows workpiece both sides basal plane respectively against on lateral bolster fagging, with interior six
Angle spanner distinguishes rotary slotted elastomer block housing screw, three gripping blocks is contacted workpiece successively respectively；Then vacuum is opened to inhale
The compressed air valve of attached component, vacuum cup tense workpiece sole plane；Finally the rotary slotted elastomer block of high torque is used again
Housing screw, workpiece is set to be fixed in two horizontal direction reliable grips using the elastic deformation for elastomer block of slotting, it is quick so as to reach
The purpose of workpiece is clamped, avoids clamping force excessive and causes workpiece deformation and the generation of position error.
The beneficial effects of the utility model are, simple to operate, can not only fast positioning clamping fix workpiece, Er Qieneng
Workpiece deformation and position error in clamping process are reduced, so as to improve the machining accuracy of part and processing efficiency.
