Adopt this structure, regulate the lifting of V-block by the engaged transmission of gear, tooth bar and the guiding of guide key groove, workpiece is contrasted to locating template and compare completely behind location, utilize the stiction after regulating handle and gear shaft are tightened that V-block is fixed.

As a kind of optimal way of technique scheme, described two V-block detent mechanisms are arranged on and are clamped on platform by a movable plate, and described movable plate can slide clamping on platform along the direction vertical with the axis of V-block.

Adopt this structure, the workpiece of having good positioning can be pushed into processing district and clamp, process, after clamping, fixture can be retracted into initial position and carry out the location of next workpiece, improve the efficiency of producing; Fixture and processing part are separated simultaneously, can better protect fixture, ensure the positioning precision of fixture.

As the another kind of optimal way of technique scheme, described two V-block detent mechanisms can slide along the axis of V-block.

Adopt this structure, can regulate the spacing between two V-block detent mechanisms for the workpiece of different length, can position shorter workpiece, increase the scope of application.

Further preferred as technique scheme, described locating template can slide along the axis of V-block.

Adopt this structure, use portable locating template, can make locating template near workpiece, improve the precision of location.

In sum, adopt technique scheme, the present invention has reached following beneficial effect with respect to prior art:

By double V-shaped detent mechanism, can carry out conveniently workpiece, accurately, effective location, improve the precision of processing, reduce production costs, improve the quality of product, enhance productivity.

Brief description of the drawings

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further, wherein:

Fig. 1 is the structural representation of the present invention for the preferred embodiment of the fixture of silicon wafer butting machine;

Fig. 2 is the gear shaft of Fig. 1 illustrated embodiment and the structural representation of regulating handle cooperation place.

Detailed description of the invention

What Fig. 1-Fig. 2 showed is the preferred embodiment of the present invention for the fixture of silicon wafer butting machine.As shown in Figure 1, the fixture for silicon wafer butting machine of present embodiment, is arranged on and clamps on platform 4, comprises V-block detent mechanism 2 and locating template 1.

Described V-block detent mechanism 2 comprises V-block 22, V-block base plate 21, guide key groove 26, tooth bar 23 and gear 24, described V-block 22 is fixed on V-block base plate 21, described tooth bar 23 is fixed on the side of V-block 22, described gear 24 coordinates transmission V-block with tooth bar 23, makes it carry out lifting along the guiding of guide key groove 26; Wherein, be provided with isometrical through hole (not showing on figure) on gear 24, described through hole is through to gear shaft 27 places, tightens and be combined with regulating handle 25 in through hole.

The end of preferred described regulating handle 25 extends to outside gear 24.Such structure is convenient to adjust the position of travelling gear 24 and tooth bar 23.
