Described adjustment bolt is sleeved on after described hemispherical pad through described through hole and is fixed in described adjustment screw, described elastomer fit between described grip block and pedestal adjustment bolt on;

The bolt head lower surface of described adjustment bolt fits in the plane of described hemispherical pad, and the sphere of described hemispherical pad fits in described ellipse hole.

Wherein: described body is inverted T-shaped.

Wherein: described elastomer is Compress Spring.

As can be seen here, machining of the present utility model has following technique effect with improvement fixture:

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 decomposing schematic representation of the utility model machining with improvement fixture.

Fig. 2 has shown combination cross-sectional schematic of the present utility model.

The specific embodiment

Referring to Fig. 1 and Fig. 2, shown improvement fixture for machining of the present utility model.

Described machining comprises pedestal 1, grip block 2, elastic component 3, hemispherical pad 4, set bolt 5 and adjusts bolt 6 with improvement fixture.

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 on to suitable position.

Optionally, described body 112 is inverted T-shaped, to embed in inverted T-shaped groove, 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 ellipse hole 23.

Described adjustment bolt 6 is sleeved on after described hemispherical pad 4 through described through hole 23 and is fixed in described adjustment screw 121, described elastomer 3 be sleeved between described grip block 2 and pedestal 1 adjustment bolt 6 on.

Wherein, the bolt head lower surface of described adjustment bolt 6 fits in the plane of described hemispherical pad 4, the sphere of described hemispherical pad 4 fits in described ellipse hole 23, thus, the thrust of adjusting bolt 6 acts on described hemispherical pad 4 all the time downwards, thereby has guaranteed to adjust the chucking power of bolt 6.

Optionally, described elastomer 3 is Compress Spring.

Thus referring to Fig. 2, the application's fixture pushes clamping to workpiece, comes 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, machining of the present utility model has the following advantages with improvement fixture tool:

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.
