As shown in Figures 1 to 4,
A kind of self-regulation clamp fixture of the present utility model, include support 1, support 1 is provided with the first fixed mechanism 2 and the second fixed mechanism 3 be oppositely arranged, first fixed mechanism 2 comprises the first pull bar 21, first pressing plate 22 and the first pole 23, middle part and first pole 23 of the first pressing plate 22 are hinged, outboard end and first pull bar 21 of the first pressing plate 22 are hinged, its medial extremity is inwardly convexly equipped with the first pressure head 22a, second fixed mechanism 3 comprises the second pull bar 31, second pressing plate 32 and the second pole 33, middle part and second pole 33 of the second pressing plate 32 are hinged, outboard end and second pull bar 31 of the second pressing plate 32 are hinged, its medial extremity is inwardly convexly equipped with the second pressure head 32a, first pull bar 21 and the second pull bar 31 are connected to the two ends of pressing plate balancing pole 4, are matched with cylinder 5 by cylinder connecting rod 51 in the center of pressing plate balancing pole 4.
First pole 23 is hinged with the contiguous block be fixed on support 1, and the second pole 33 is also hinged with the contiguous block be fixed on support 1.
In embodiment, the first pressing plate 22 staggers with described second pressing plate 32 and arranges, and the first pressing plate 22 is downward-sloping, and the second pressing plate 32 is inclined upwardly.
Stagger arrange the first pressing plate 22 and the second pressing plate 32 make two compress point be positioned in different level heights, the stress surface of processing work J can be increased like this, avoid processing work J local pressure excessive and cause it to be extruded distortion.
In embodiment, the center of pressing plate balancing pole 4 coordinates with described cylinder connecting rod 51 is hinged.Hinged cooperation makes pressing plate balancing pole 4 can swing around pin joint, thus the first fixed mechanism 2 and the second fixed mechanism 3 are completed better from main regulation.
In embodiment, support 1 is provided with the alignment pin 6 suitable with processing work J.
In embodiment, the top of support 1 is provided with limited block 7.
In embodiment, the number of limited block 7 is two pieces, and two pieces of limited blocks 7 are symmetrical arranged.
In embodiment, the bottom of support 1 is provided with guide pad 8.
In embodiment, the number of guide pad 8 is three pieces, and three pieces of guide pads 8 are in the distribution of falling isosceles triangle.
In embodiment, support 1 is made up of the base plate 11 of horizontally set and the riser 12 of vertical setting, and base plate 11 and riser 12 form inverted T-shape structure.
In embodiment, riser 12 is provided with cylinder lining bar 52, cylinder 5 is fixed on cylinder lining bar 52.Cylinder lining bar 52 is set and can makes the fixing convenient, stable of cylinder 5.
Operation principle:
As shown in Figure 4, when putting processing work J, transfer processing work J along three pieces of guide pads 8, and locate with alignment pin 6, alignment pin 6 is positioned at the lower central of processing work J; After placement completes, the bottom of processing work J is placed in the semi-surrounding structure of three pieces of guide pads 8 formations, and its top is between two pieces of limited blocks 7.
During compacting processing workpiece J, cylinder 5 startup ejects cylinder connecting rod 51, the pressing plate balancing pole 4 of cylinder connecting rod 51 front end is travelled forward, the reach of pressing plate balancing pole 4 drives the first pull bar 21 of the first fixed mechanism 2 to move forward, because the middle part of the first pressing plate 22 and the first pole 23 are hinged, first pull bar 21 reach makes the first pressing plate 22 rotate around the pin joint of the first pressing plate 22 and the first pole 23, move outside the left side of the first pull bar 21, press in the right side of the first pull bar 21, thus make the first pressure head 22a compacting processing workpiece J on the first pressing plate 22.
Same, the reach of pressing plate balancing pole 4 drives the second pull bar 31 of the second fixed mechanism 3 to move forward, because the middle part of the second pressing plate 32 and the second pole 33 are hinged, second pull bar 31 reach makes the second pressing plate 32 rotate around the pin joint of the second pressing plate 32 and the second pole 33, move outside the right side of the second pull bar 31, press in the left side of the second pull bar 31, thus make the second pressure head 32a compacting processing workpiece J on the second pressing plate 32.
This clamp fixture controls the first fixed mechanism 2 of both sides by a pressing plate balancing pole 4 simultaneously and the second fixed mechanism 3 fixes processing work J, because the first fixed mechanism 2 and the second fixed mechanism 3 are oppositely arranged, and fixed mechanism center platen and pull bar are hinged, because pole is hinged in the middle part of pressing plate; In compacting processing workpiece J process, by the motion of each pin joint, first fixed mechanism 2 and the second fixed mechanism 3 can realize from main regulation, thus make the first pressure head 22a contact more tight with processing work J with the first pressure head 22a, ensure fixing reliability.
After machining, cylinder 5 starts band dynamic air cylinder connecting rod 51 and retracts, thus move after making pressing plate balancing pole 4, move after the rear shipper pole of pressing plate balancing pole 4 moves the first pull bar 21 of the first fixed mechanism 2, move after the first pull bar 21 and make the first pressing plate 22 rotate backward around the pin joint of the first pressing plate 22 and the first pole 23 and turn up; Same, move after pressing plate balancing pole 4 and also make the second pressing plate 32 turn up, the first pressing plate 22 and turning up of the second pressing plate 32 make the first pressure head 22a and the second pressure head 32a depart from processing work J, thus can be taken off by processing work J easily.
Treat that between accurately machined processing work J, size has trickle gap, and the size disparity of blank workpiece is often larger, can automatically regulate in the process that the fixed mechanism of this clamp fixture clamps at the same time, make each compression be pressed onto workpiece, can not occur because of the slight change of workpiece size that pressure is empty or the situation of workpiece compressive strain.
Most preferred embodiment of the present utility model is illustrated, and the various change made by those of ordinary skill in the art or remodeling all can not depart from scope of the present utility model.
