Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
Fig. 1 and Fig. 2 are referred to, the utility model embodiment includes：
A kind of synchronous compressing fixture, including：Upper plate 3, lower shoe 1, the fixture support for connecting upper plate 3 and lower shoe 1
Plate 2, compressed oil cylinder 6 is fixedly installed in the lower surface of the upper plate 3, the piston-rod end of the compressed oil cylinder 6, which is fixed, to be connected
A restoring board 5 is connected to, the axle center of the piston rod is located at same straight line with the axle center of restoring board 5, and the outer end of the restoring board 5 is consolidated
Surely three groups of hold-down mechanisms are provided with, every group of hold-down mechanism includes：Compressing pull rod 7, pressure arm 9, described compress draw one end of 7 bars to fix
Restoring board 5 is connected to, the other end of compressing pull rod 7 is connected to the lower end of pressure arm 9 by rotating shaft, and the upper end of the pressure arm 9 is set
There is pressure head 12, the middle part of pressure arm 9 offers through hole, and pressure arm pin 10 is provided with through hole, and the pressure arm pin 10 is fixed on upper plate 3
At the fixed plate 14 of upper surface.The lower section of the restoring board 5 is provided with pull bar connecting plate 8, restoring board 5 and pull bar connecting plate 8 it
Between connected by back-moving spring 4, one end of the back-moving spring 4 connection restoring board 5, other end cylinder lever connecting rod connecting plate 8.
Further, the shape of cross section of the restoring board 5 is uniformly distributed in restoring board using circle, three groups of hold-down mechanisms
5 so that when pushing, every group of hold-down mechanism can be moved downward synchronously compressed oil cylinder 6, caused by avoiding discontinuity
Compression action is asynchronous.
Further, the contact site periphery of the compressing pull rod 7 and upper plate 3 is provided with pilot sleeve 13.Prevent from compressing
Pull bar 7 shifts when pushing, and so as to influence the position of pressure arm 9, improves compression precision.
