Abstract
The utility model relates to a clamping device, in particular to a double floating top block clamping device. The double floating top block clamping device comprises a clamp body, a bolt used as a power exerting device, an upper clamping block and a lower clamping block which are used for compactly pressing the surfaces of workpieces, and wedge blocks used for compactly pressing the upper clamping block and the lower clamping block, wherein horizontal holes which are used for slidingly matched with the wedge blocks and vertical holes which limit transverse freedom degree of both the upper clamping block and the lower clamping block are formed in the clamp body, the bolt is arranged on the clamp body, and abuts against one ends of the wedge blocks, and the other ends of the wedge blocks are matched with the wedge surfaces of both the upper clamping block and the lower clamping block in a sliding mode. The double floating top block clamping device can compactly press two corresponding surfaces of the workpieces to be machined, structure is simple, and operation is convenient.
Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of two unsteady jacking block clamping device.
Background technology
No matter be traditional machinery manufacturing industry, or the modern mechanical manufacturing industry, the effect of jig all is very important, the core of jig then is clamping device.In mechanical processing process, to the location of workpiece to be processed, clamp the link that is absolutely necessary, can guarantee the precision of processing to the location of workpiece, clamp and can prevent then that part flies out in the process and cause accident.Owing to the clamping device of relative two faces of clamping work pieces is simultaneously now seldom arranged, so be badly in need of a kind of can compressing simultaneously for relative two faces and simple in structure of processing work, easy to operate clamping device.
The utility model content
The technical problems to be solved in the utility model provides a kind of can compressing simultaneously for relative two faces and simple in structure of processing work, easy to operate clamping device.
In order to solve the problems of the technologies described above, the utility model provides a kind of two unsteady jacking block clamping device, comprise chuck body, as the bolt of force application apparatus, be used for the workpiece pressing surface last fixture block and following fixture block, compress the wedge of fixture block and following fixture block, be provided with the lateral aperture that is slidingly matched with wedge in the described chuck body, and the vertical hole of fixture block and the horizontal free degree of following fixture block is gone up in restriction, bolt is installed on the chuck body, itself and wedge one end offset, and the lozenges of fixture block was slidingly matched under the other end of wedge and last fixture block reached.
The two unsteady jacking block clamping devices of the utility model, when tightening bolt, wedge in the lateral aperture of bolt extrusion clamp body is to left movement, and last fixture block and following fixture block are reached the effect that compresses simultaneously for relative two faces of processing work by outwards motion of wedge extruding.
Adopt the two unsteady jacking block clamping device of technique scheme to have following advantage: 1, because the two unsteady jacking block clamping devices of the utility model are provided with fixture block, following fixture block, can outwards slide simultaneously, so can clamp simultaneously for relative two faces of processing work; 2, because the two unsteady jacking block clamping devices of the utility model only just can reach the clamping function with chuck body, bolt, wedge, last fixture block and following fixture block, so simple in structure, easy to operate.
As preferred version, it is laterally mobile to consider that fixture block and following fixture block may produce when clamping work pieces, and therefore the influence location can adopt in last fixture block and following fixture block the sliding pin that limits its horizontal free degree is set.
As preferred version, consider that fixture block and following fixture block may break away from chuck body in the course of the work, therefore can adopt in last fixture block and following fixture block extension spring is set.
As preferred version, consider when tightening bolt extruding wedge to produce friction, therefore can adopt the ball that reduces to rub in the setting of wedge V-type face.
Description of drawings
Fig. 1 is the structural representation of the two unsteady jacking block clamping devices of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing technical solutions of the utility model are further specified:
As shown in Figure 1, the utility model provides a kind of thrust clamping device, comprise chuck body, as the bolt 1 of force application apparatus, be used for the workpiece pressing surface last fixture block 4 and following fixture block 5, compress the wedge 3 of fixture block 4 and following fixture block 5, be provided with the lateral aperture that is slidingly matched with wedge 3 in the chuck body, and the vertical hole of fixture block 4 and the following fixture block 5 horizontal frees degree is gone up in restriction, bolt 1 is installed on the chuck body, itself and wedge 3 one ends offset, and the lozenges of fixture block 5 was slidingly matched under the other end of wedge 3 and last fixture block 4 reached; Be provided with the sliding pin that limits its horizontal free degree in last fixture block 4 and the following fixture block 5; Last fixture block 4 and 5 of following fixture blocks are provided with extension spring; Wedge 3 is provided with the V-type groove with bolt 1 face of offseting, and is provided with the ball 2 of reducing friction in the V-type groove.
Specifically be to use method to be: tighten bolt 1, make wedge 3 in the lateral aperture of bolt 1 extrusion clamp body to left movement, last fixture block 4 and play fixture block 5 are reached the effect that compresses for processing work by outside the moving of wedge 3 extruding; The sliding pin that is provided with in last fixture block 4 and the following fixture block 5 limits the free degree of its horizontal direction when it slides, guarantee that it only can move in the vertical direction; The extension spring that is provided with in last fixture block 4 and the following fixture block 5 makes it can not break away from chuck body in sliding process; Wedge 3 and bolt 1 ball in the V-type groove of face that offsets, it can reduce the friction of generation when bolt 1 extruding wedge 3.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; such as the sliding pin that limits its horizontal free degree etc. is set in fixture block on described and the play fixture block, these also should be considered as protection domain of the present utility model, and these can not influence effect and the practical applicability of the utility model enforcement.
