Therefore, be badly in need of a kind of fixture, to solve the problem.
Utility model content
The purpose of this utility model is to provide a kind of fixture, needing to expend the more operating time, causing the problem that workpiece treatment effeciency is too low for solving the locking and unlocking of fixture in prior art.
For realizing above-mentioned utility model object, the utility model provides a kind of fixture, comprising:
Body, the first through hole described body offering clamping station and be communicated with described clamping station;
The grip block that can move along described first through hole;
Push rod, described push rod is fixedly connected with described grip block, and described grip block can be moved along described first through hole by described push rod with driving;
The fixed block be connected with described body, described fixed block offers the second through hole, and described push rod passes described second through hole and matches with described grip block;
Be linked in the elastic component on described push rod, the two ends of described elastic component offset with described grip block and fixed block respectively, and when described grip block is positioned at described first through hole, described elastic component is in compressive state.
As further improvement of the utility model, described elastic component is spring or shell fragment.
As further improvement of the utility model, described grip block is arranged with installing hole, in described push rod and described installing hole, is provided with the screw thread that can be fitted to each other.
As further improvement of the utility model, described push rod is provided with grip part in the one end away from described grip block.
As further improvement of the utility model, described grip part is coated with anti-skidding silica gel.
As further improvement of the utility model, described fixed block and described body split manufacture.
Compared with prior art, the beneficial effects of the utility model are: by elastic component sheathed on push rod, these elastic component two ends support respectively on fixed block and grip block, when after the power of being moved in the first through hole by push rod applying grip block, grip block is positioned at the first through hole, elastic component is in compressive state, now can place workpiece to be processed in clamping station, unclamp push rod subsequently, grip block under the effect of elastic component towards away from the motion in the direction of the first through hole, thus the workpiece to be processed in clamping clamping station, its structure is simple, greatly improve the treatment effeciency of workpiece.
Accompanying drawing explanation

Fig. 2 is sectional view when fixture is positioned at clamped condition in the application one embodiment.
Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, the utility model is described in detail; but should be noted that; these embodiments are not limitation of the utility model; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection domain of the present utility model.
Ginseng Fig. 1 and Fig. 2, introduces a detailed description of the invention of the application's fixture 100.In the present embodiment, this fixture 100 comprises body 10, grip block 40 and push rod 20.
Body 10 offers clamping station 11, clamping station 11 is for holding workpiece (not shown) to be processed, workpiece is clamped and is locked on clamping station 11 under the effect of fixture 100, and the operating principle of the clamping of this part and locking will describe in detail hereinafter.
Coordinate with reference to Fig. 2, body 10 also offers and the first through hole 12 clamping station 11 and be communicated with, grip block 40 is arranged in this first through hole 12 movably.The shape of grip block 40 is set to suitable with the direction of motion limiting this grip block 40 with the first through hole 12, " shape of grip block 40 is suitable with the first through hole 12 " mentioned here refers to: the plane vertical with grip block 40 direction of motion cut the shape of grip block 40 and the first through hole 12 and size identical, grip block 40 has been defined unique motion path when moving in the first through hole 12, and the motion of the first through hole 12 pairs of grip blocks 40 plays guiding function.
Push rod 20 can, under the effect of external force, drive grip block 40 to move along the first through hole 12.In present embodiment, this grip block 40 is arranged with installing hole (not shown), is provided with the screw thread (not shown) that can be fitted to each other in push rod 20 and installing hole, to simplify the installation difficulty of push rod 20 and grip block 40.
Fixture 100 also comprises the fixed block 30 be connected with main body 10, this fixed block 30 offers the second through hole 31, and above-mentioned push rod 20 passes the second through hole 31 and matches with grip block 40.Second through hole 31, for limiting motion path for push rod 20, ensures the stability that push rod 20 coordinates with grip block 40.
In one preferred embodiment, fixed block 30 can be and body 10 split manufacture.
Push rod 20 is provided with grip part 21 in the one end away from grip block 40, grip part 21 is coated with anti-skidding silica gel (not shown), so that the applying of external force and operation.
Push rod 20 is arranged with elastic component 50, the two ends of this elastic component 50 offset with grip block 40 and fixed block 30 respectively, and when grip block 40 is positioned at the first through hole 12, elastic component 50 is in compressive state.
In one preferred embodiment, elastic component 50 can be spring or shell fragment.
In concrete use procedure, first pull push rod 20, make grip block 40 make a concession in the first through hole 12, now elastic component 50 is in compressive state (as shown in Figure 1), and workpiece can be positioned on the clamping station 11 of body 10; Unclamp push rod 20 subsequently, elastic component 50 promotes grip block and moves (as shown in Figure 2) towards the direction of clamping work pieces, realizes the locking to workpiece.
The utility model is by sheathed elastic component on push rod, these elastic component two ends support respectively on fixed block and grip block, when after the power of being moved in the first through hole by push rod applying grip block, grip block is positioned at the first through hole, elastic component is in compressive state, now can place workpiece to be processed in clamping station, unclamp push rod subsequently, grip block under the effect of elastic component towards away from the motion in the direction of the first through hole, thus the workpiece to be processed in clamping clamping station, its structure is simple, greatly improves the treatment effeciency of workpiece.
