Description
Technical field
The utility model belongs to car body frock technical field, especially relates to a kind of self adaptation hold down gag for fixing plate.
Background technology
In engineering machinery tooling device, because big machinery class punching press sheet metal component easily produces deformation, precision cannot reach so high requirement, causes between sheet metal component diverse location and produces difference in height, when making frock, fixing more difficult.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of self adaptation hold down gag for plate, solves the problem that punching press plate deformation band comes, does not require the high accuracy of pressed sheet part, reduce costs.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of self adaptation hold down gag for plate, comprise connector and be located at the some compressing units on connector, described compressing unit comprises compact heap, Compress Spring, bearing pin, axle sleeve and locking nut, compact heap is provided with the through hole mated with bearing pin, one end of bearing pin is that cross-sectional surface amasss the jacking block being greater than through hole, jacking block when not acting on does not contact with between compact heap, the other end of locking nut and bearing pin passes through screw threads for fastening, do not fix between locking nut and compact heap, axle sleeve and Compress Spring are located at through-hole wall, and be surrounded on bearing pin, Compress Spring is connected between axle sleeve and jacking block, distance between locking nut and jacking block is greater than the length of through hole, bearing pin is acted in through hole to slide located by jacking block and Compress Spring.When thickness of slab when between plate changes, Compress Spring will automatic telescopic, reaches the effect of the different thicknesss of slab adapting to plate.
Further, described compact heap comprises fixed part and compressed part, and through hole is located in compressed part, and fixed part is fixedly connected with by screw with connector.
Further, described fixed part and compressed part are cuboid, and on vertical direction, dislocation connects, and are formed
shape.
Further, described screw thread is located at the position that bearing pin screws with locking screw parent phase.
The advantage that the utility model has and good effect are: structure is simple, solves the problem being difficult to fix that plate deformation brings, does not require the high accuracy of pressed sheet part, reduce costs.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figures 1 to 3, a kind of self adaptation hold down gag for fixing plate, the some compressing units comprising connector 9 and be located on connector 9, compressing unit comprises compact heap, Compress Spring 6, bearing pin 3, axle sleeve 5 and locking nut 4, compact heap is provided with the through hole mated with bearing pin 3, one end of bearing pin 3 is that cross-sectional surface amasss the jacking block 8 being greater than through hole, jacking block 8 when not acting on does not contact with between compact heap, locking nut 4 passes through screw threads for fastening with the other end of bearing pin 3, and screw thread is located at the position that bearing pin 3 screws mutually with locking nut 4.Do not fix between locking nut 4 and compact heap, axle sleeve 5 and Compress Spring 6 are located at through-hole wall, and be surrounded on bearing pin 3, Compress Spring 6 is connected between axle sleeve 5 and jacking block 8, distance between locking nut 4 and jacking block 8 is greater than the length of through hole, and bearing pin 3 is acted in through hole to slide located by jacking block 8 and Compress Spring 6.
Compact heap comprises fixed part 2 and compressed part 1, and through hole is located in compressed part 1, and fixed part 2 is fixedly connected with by screw 7 with connector 9.Fixed part 2 and compressed part 1 are cuboid, and on vertical direction, dislocation connects, and are formed
shape.
As shown in Figure 3, during installation, each compressing unit was passed through screw 7 and was fixedly connected with connector 9.Self adaptation hold down gag of the present utility model is applied on compression tooling equipment, for compressing the punching press sheet metal component of fine height difference.When thickness of slab when between plate changes, Compress Spring 6 will automatic telescopic.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
