The technical problems to be solved in the utility model is: when processing work, how workpiece is carried out effectively fixing extremely important to guarantee machining accuracy.

For addressing the above problem, the utility model discloses a kind of workpiece clamping structure, comprise clamping plate, described clamping plate is provided with many inverted T-shaped grooves that extend in parallel, and it is characterized in that:

On described clamping plate, be also provided with at least one clamping device;

Described clamping device comprises pedestal, grip block, elastic component, set bolt and adjustment bolt;

Described pedestal is inverted L-shaped, comprise be positioned at below strip body and from the upwardly extending cylinder of described body one side, described body is that inverted T-shaped to slide in described inverted T-shaped groove;

The opposite side of described body is provided with the adjustment screw of perforation, and the side that described cylinder is positioned at described adjustment screw one side is provided with cancave cambered surface;

And a fixing threaded hole that connects described cylinder and body, in described fixing threaded hole is placed through for described set bolt;

Described grip block is strip, and its one end is the convex arc section suitable with described cancave cambered surface, and the other end is the pushing portion pushing in workpiece, and the middle part of described grip block is penetrated with through hole; Described adjustment bolt is through described through hole being fixed in described adjustment screw, described elastomer fit between described grip block and pedestal adjustment bolt on.

Wherein: described elastomer is Compress Spring.

As can be seen here, workpiece clamping structure of the present utility model has following technique effect:

1, can carry out firm clamping to workpiece, avoid machining accuracy to exert an influence;

2, simple in structure, handling and maintenance are convenient, and practicality is stronger.

Detailed content of the present utility model can obtain by explanation described later and institute's accompanying drawing.

Accompanying drawing explanation

Fig. 1 has shown the structural representation of the utility model workpiece clamping structure.

Fig. 2 has shown the structural representation of the utility model clamping device.

Fig. 3 has shown use schematic diagram when the utility model carries out clamping.

The specific embodiment

Referring to Fig. 1, shown workpiece clamping structure of the present utility model.

Described workpiece clamping structure comprises clamping plate 7, and described clamping plate 7 is provided with many inverted T-shaped grooves 71 that extend in parallel.

On described clamping plate 7, be also provided with at least one clamping device.

Referring to Fig. 2, described clamping device comprises pedestal 1, grip block 2, elastic component 3, set bolt 5 and adjusts bolt 6.

Described pedestal 1 is inverted L-shaped, comprise be positioned at below strip body 112 and from the upwardly extending cylinder 113 of described body 112 1 side, the opposite side of described body 112 is provided with the adjustment screw 121 of perforation, and the side that described cylinder 113 is positioned at described adjustment screw 121 1 sides is provided with cancave cambered surface 123.

And a fixing threaded hole 111 that connects described cylinder 113 and body 112, in described fixing threaded hole 111 is placed through for described set bolt 5, thereby fixture is fixed in inverted T-shaped groove 71.

Wherein, described body 112 is inverted T-shaped, to embed in inverted T-shaped groove 71, slides.

Described grip block 2 is strip, and its one end is the convex arc section 21 suitable with described cancave cambered surface 123, and the other end is the pushing portion 22 pushing in workpiece, and the middle part of described grip block 2 is penetrated with through hole 23.

Described adjustment bolt 6 is through described through hole 23 and be fixed in described adjustment screw 121, described elastomer 3 be sleeved between described grip block 2 and pedestal 1 adjustment bolt 6 on.

Optionally, described elastomer 3 is Compress Spring.

Thus referring to Fig. 2, the application's fixture is in the interior slip of inverted T-shaped groove 71 of clamping plate 7, and workpiece is pushed to clamping, in figure, only show the clamping of a face of workpiece, can utilize on a plurality of and be respectively provided to a few fixture, come effectively workpiece to be pushed to clamping, because the fixture adjusting range in the application is good, grip block can regulate and accordingly without pedestal is moved, therefore adjust more simple and efficient.

Known by said structure, workpiece clamping structure tool of the present utility model has the following advantages:

1, can carry out firm clamping to workpiece, avoid machining accuracy to exert an influence;

2, simple in structure, handling and maintenance are convenient, and practicality is stronger.

It is evident that above description and to record be only for example rather than in order to limit disclosure of the present utility model, application or use.Although described in an embodiment and be described in the drawings embodiment, but the optimal mode that the utility model does not limit by accompanying drawing example and the conduct of describing is in an embodiment thought to be at present to implement the specific examples of instruction of the present utility model, scope of the present utility model will comprise any embodiment of the description that falls into above and appended claim.
