Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
A kind of easily-deformable frame shape clamping workpiece system of the present embodiment, as depicted in figs. 1 and 2, including pedestal 100 and setting exist
Clamping mechanism 200 on pedestal 100, as shown in Fig. 2, frame shape workpiece 300 is quadrilateral structure, its in the present embodiment is specially square
Shape frame, such as mobile phone metal center, have two groups of adjacent sides, and first group of adjacent side is X to side 310 and Y-direction side
320, second group of adjacent side is X to side 330 and Y-direction side 340；Clamping mechanism 200 includes first with frame shape workpiece 300
The positioning mechanism 210 that group adjacent side 310,320 is correspondingly arranged and second group of adjacent side 330,340 with frame shape workpiece 300
In frame shape workpiece 300 is folded in by the hold-down mechanism 220 being correspondingly arranged, positioning mechanism 210 and hold-down mechanism 220, thus to square
The X of shape frame shape workpiece 300 to Y-direction effective position and compression；Hold-down mechanism 220 includes cylinder 221 and is removably mounted on
Elastic compression component 222 on the piston rod of cylinder 221, elastic compression component 222 is for being pressed on the corresponding of frame shape workpiece 300
On side, elastic compacting part 222 is vertically pressed in the respective side edge of frame shape workpiece 300 in the present embodiment.
Specifically, first group of adjacent side of positioning mechanism 210 described in the present embodiment and frame shape workpiece 300 is correspondingly arranged,
Can be X to side 310 and Y-direction side 320 be correspondingly arranged a set of positioning mechanism 210 perhaps cover more positioning mechanism or X to
Positioning mechanism 210 at side 310 and Y-direction side 320 is in varying numbers；Similarly, the of hold-down mechanism 220 and frame shape workpiece 300
Two groups of adjacent sides are correspondingly arranged, can be X to side 330 and Y-direction side 340 be correspondingly arranged a set of hold-down mechanism 220 or
Person covers hold-down mechanism 220 more or X is in varying numbers to the hold-down mechanism 220 at side 330 and Y-direction side 340.Hold-down mechanism
220 compacting part is dismountable elastic compression component 222, can be adapted to not by selecting different elastic compression components 222
With the clamping task of pressing force demand, pressing force is convenient for adjusting；222 pressing force of elastic compression component is small and has buffer function,
So as to reduce the deformation generated when easily-deformable frame shape clamping workpiece, to reduce since deformation is to the unfavorable shadow of measurement accuracy
It rings.
Further, to realize automated exchanged cutter, and then clamping workpiece efficiency and measurement efficiency are improved, mounting and clamping system 200 is also
Including PLC control system (not shown), be additionally provided on pedestal 100 for incude frame shape workpiece 300 close to switch 400,
Cylinder 221 is communicated to connect with PLC control system close to switch 400.When close switch 400 senses tested frame shape workpiece
300, PLC control system is sent the signal to, PLC control system controls 221 auto-extending piston rod of cylinder, and the outreach is big
In the stroke that theory is stretched out, the i.e. meeting of cylinder 221 over-voltage workpiece (general over-voltage 1mm or so), after cylinder 221 is fully extended, bullet

Component 222 is mounted in elastic compression member mounting holes, is equipped with jackscrew in jackscrew mounting hole 224 and is positioned bullet in a manner of holding out against
Property compacting part 222.When dismantling elastic compression component 222, only it need to unscrew jackscrew and disengage it from and elastic compression component 222 is determined
Position, then removes former elastic compression component 222, replaces with new elastic compression component 222, re-operate jackscrew positioning elastic
Compacting part 222.
Guide groove 110 is equipped on pedestal 100, a part of mounting base 223 is embedded in guide groove 110, is installed by 110 Duis of guide groove
Seat 223 is oriented to the movement of cylinder piston rod, is further ensured that the compression stable action of elastic compression component 222.
Elastic compacting part 222 is spring-loaded plunger in the present embodiment, while the front end of spring-loaded plunger is equipped with rubber squeeze head
225, further to buffer the extruding to frame shape workpiece 300.Certainly, it may be other spring parts, can be not particularly limited.
It is equilibrium assignment to the pressing force of frame shape workpiece 300, avoids single-point from compressing, in the present embodiment, set in mounting base 223
There are multiple elastic compression member mounting holes and the multiple jackscrews being arranged in a one-to-one correspondence with elastic compression member mounting holes to install
Hole is equipped with elastic compression component 222 in each elastic compression member mounting holes, is equipped with jackscrew in each jackscrew mounting hole 224.Such as
Shown in Fig. 1 and Fig. 2, is set in mounting base 223 there are two elastic compression component 222, compression positioning is carried out by jackscrew respectively.Certainly,
The quantity of elastic compression component 222 can determine that size is bigger by the side dimension of frame shape workpiece 300, can suitably increase elastic pressure
The quantity of tight component 222, as to make pressing force balanced as possible.
In the present embodiment, the quantity of hold-down mechanism 220 is two sets, with second group of adjacent side 330 of frame shape workpiece 300,
340 are arranged in a one-to-one correspondence；The quantity of positioning mechanism 210 is two sets, first group of adjacent side 310,320 with frame shape workpiece 300
It is arranged in a one-to-one correspondence.Preferably, the center position of its respective side is arranged in each hold-down mechanism 220 and positioning mechanism 210, makes
Entire 300 stress equalization of frame shape workpiece.
For positioning mechanism 210 comprising positioning seat 211 and the positioning pin 212 being installed on positioning seat 211, positioning pin
212 are located at the outside of first group of adjacent side 310,320 of frame shape workpiece 300.The settable many places of positioning mechanism 210, according to frame shape
First group of adjacent side 310,320 specific sizes of workpiece 300 determine, with uniform location.
As depicted in figs. 1 and 2, in the present embodiment, a preferred embodiment the most, setting is by two suits on pedestal 100
Clamp mechanism 200, when being measured after wherein a set of clamping mechanism 200 carries out clamping to a frame shape workpiece 300, another set of clamping mechanism
