Specific embodiment

Below in conjunction with the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear, complete Site preparation description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments. Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts Every other embodiment, fall within the protection scope of the utility model.

As shown in Figure 1-3, a kind of flexible fixture, including pedestal 1,1 upper surface of pedestal are welded and connected with bracket 2, institute The outer wall on the right side and cylinder 5 of stating bracket 2 is welded to connect, and is equipped with sleeve 9, the lower end of the sleeve 9 inside the cylinder 5 It is welded with disk 8,9 threaded upper ends of sleeve are connected with shank of bolt 12, concordant with 5 top of cylinder on the shank of bolt 12 to locate to weld It is connected to annulus 11, the annulus 11 and 5 inner wall sliding contact of cylinder, the interior welds of the cylinder 5 have retention bead 14, described Retention bead 14 is located at the top of disk 8, and circle is fixedly welded with fixture placement plate 3, the left side of the bracket 2 on the pedestal 1 Equipped with fixture placement plate 3, the fixture placement plate 3 is welded on pedestal 1.

Specifically, the left side of the bracket 2 is welded with pivoting support 13, rotated on the pivoting support 13 by pin shaft 15 It is connected with hand compression bar 10.

Specifically, being cased with spring 7 on 9 outer wall of sleeve and with lamination 6, the same lamination 6 is placed on two adjacent Between spring 7, the same lamination 6 is slidably connected with sleeve 9 and cylinder 5.

Specifically, the upper surface of the fixture placement plate 3 and the lower surface of disk 8 are bonded with rubber pad 4.

Specifically, the hand compression bar 10 is equipped with notch close to 12 top side of shank of bolt.

In use, workpiece is placed in fixture placement plate 3 first, pin shaft 15 of the hand compression bar 10 on rocker bar bearing 13 It rotates down, is contacted at the top of the notch on hand compression bar 10 and shank of bolt 12, when hand compression bar 10 rotates down, shank of bolt 12 can be by The downward pressure of hand compression bar 10, when shank of bolt 12 moves downward, will drive set since shank of bolt 12 is threadedly coupled with sleeve 9 Cylinder 9 moves downward, and the pressure length downward by annulus 11 of spring 7 shortens at this time, and spring 7 drives with 6 slide downward of lamination, directly Hand compression bar 10 is discharged after workpiece completes process to disk contact workpiece, shank of bolt 12 is acted on by the bounce of spring 7 and being driven Sleeve 9 moves upwards, until the disk 8 of 9 bottom end of sleeve welding stretches into inside cylinder 5, the same lamination 6 between spring 7 can be with Run-off the straight when shank of bolt 12 being prevented to be lifted up is cased with multiple springs 7 on sleeve 9, when a spring 7 damages, other bullets Spring 7 can still be worked with gripping clamping apparatus.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
