A corner；Above-mentioned mounting plate 52 is additionally provided at least two pneumatic claws.
Working principle: metal blank to be processed is placed in above several support devices, so that under metal blank
Surface is contacted with the portable pillar upper surface of support device, because of the metallic character of metal blank itself, so that panel surface has one
Fixed warpage and it is uneven, the portable pillar of each support device moves down a distance under the action of metal blank or does not move
It is dynamic, after the portable pillar of each support device is stablized, then one and its following table can be determined for the metal blank of side placed on it
Face rises and falls consistent supporting surface, at this time pushes up the pushing block of each support device, pushing block drive the elastic parts above it to
It is upper that push quill to move up, quill is moved up so that the steel ball contacted with quill inner wall moves up, so that
Fixes sleeve holds portable pillar tightly, the up and down of portable pillar is limited, so that the portable pillar of support device is in fixing shape
State, so that the plate for side placed on it provides the support stablized and agreed with plate lower surface, convenient for the milling equality to plate
Process operation.
When using the above-mentioned clamping jig for CNC processing, by the free movement of portable pillar in the vertical direction, make
The distance moved down can be adjusted according to the bending degree of plate to be processed placed thereon by obtaining portable pillar, to make to be processed
Plate can accurately be supported in the case where keeping itself bending state, then cooperate quill, steel ball by pushing block
And fixes sleeve, it realizes to the holding and fixation of portable pillar, so as to the supporting & stablizing of plate to be processed, reliable, by near
Being applied in combination for few three floating support components, provides a supporting surface, and the curvature contract of supporting surface and plate for plate
It closes, so that plate obtains stable support in the state of most natural, it is only necessary to which the flat processing of primary milling is carried out to plate, so that it may
Obtain an accurate plane, then by plate turn-over, so that it may surface processing is carried out under the support of planar support jig, i.e., only
Need to carry out a turn-over, so that it may complete to process the whole of plate, the process that processing is greatly saved improves production
Efficiency and precision also substantially reduce the material feeding amount of plate, reduce the waste of former material, have saved cost, the product efficiency of raising；
Secondly, the setting of its reset spring, so that giving quill one downward active force after the thrust that pushing block is subject to is shed, making
Quill is obtained to move down, thus to the driving force that the steel ball in cavity can scroll down through, so that steel ball scrolls down through, it is extensive
It is multiple, so that portable pillar is restored to move up and down, to be set by simple structure to original state so that fixes sleeve unclamps portable pillar
Meter, achieve the effect that restPose automatically makes all parts restore initial shape without adding a downward pulling force again
State, clever structure are easy to use；Again, the setting of portable pillar inner spring can both be pushed in portable pillar by plate to be processed
When, a reaction force flexible is provided to plate, plays the role of protecting plate, and can mention after the completion of sheet fabrication
The reaction force restored for one can be carried out down so that portable pillar automatically restores to initial position without manual reset
First use, in addition, by enclosing springs in outer sleeve, not only can protect spring, but also good limit is played to the circumferential direction of spring
Position effect, situations such as avoiding spring from deforming and influence to use, the setting of support column is embedded in further through stud lower part, to activity
Column integrally plays position-limiting action in the circumferential, guarantees that portable pillar can only move in the vertical direction, prevents portable pillar from shifting
And influence the precision of device entirety.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
