Adopt this structure, can the workpiece of having good positioning be pushed into the processing district and clamp, process, can anchor clamps be retracted into the location that initial position carries out next workpiece after the clamping, improve the efficient of producing; Anchor clamps and processing part are separated simultaneously, can better protect anchor clamps, guarantee the positioning accuracy of anchor clamps.

As the another kind of optimal way of technique scheme, said 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, can short workpiece be positioned, increase the scope of application to the workpiece of different length.

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

Adopt this structure, use portable locating template, can make locating template, improve locating accuracy near workpiece.

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

Through double V-shaped detent mechanism, can carry out convenience, accurate, effective location to workpiece, improve the precision of processing, reduce production costs, the quality of raising product is enhanced productivity.

Description of drawings

Do further explanation below in conjunction with the accompanying drawing specific embodiments of the invention, wherein:

Fig. 1 is the structural representation of the preferred implementation of the present invention's anchor clamps of being used for crystal silicon butt machine;

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

The specific embodiment

What Fig. 1-Fig. 2 showed is the preferred implementation that the present invention is used for the anchor clamps of crystal silicon butt machine.As shown in Figure 1, the anchor clamps that are used for crystal silicon butt machine of this embodiment are installed in and clamp on the platform 4, comprise V-block detent mechanism 2 and locating template 1.

Said V-block detent mechanism 2 comprises V-block 22, V-block base plate 21, guiding keyway 26, tooth bar 23 and gear 24; Said V-block 22 is fixed on the V-block base plate 21; Said tooth bar 23 is fixed on the side of V-block 22; Said gear 24 cooperates the transmission V-block with tooth bar 23, and it can be gone up and down along the guiding of guiding keyway 26; Wherein, on gear 24, be provided with isometrical through hole (figure is last not to be shown), said through hole is through to gear shaft 27 places, in through hole, tightens to be combined with regulating handle 25.

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

The end of preferred said regulating handle 25 is the T font.Such structure is convenient to regulating handle 25 is tightened.

Said V-block detent mechanism 2 is two, and V-block 22 coaxial being installed in are clamped on the platform 4.

As a kind of preferred; These two V-block detent mechanisms 2 are installed in through a movable plate 3 and clamp on the platform 4; Said movable plate 3 and clamping is provided with the guide rail 32 with the axis normal of V-block 22 between the platform 4, said movable plate 3 can the edge be slided clamping on the platform 4 with the direction of the axis normal of V-block 22.Further preferably between the V-block base plate 21 of said two V-block detent mechanisms 2 and movable plate 3, be provided with the guide rail with the parallel axes of V-block 22, said two V-block detent mechanisms 2 can be along the guide rail slide in opposition.
