Among the figure: 1, driving gear; 2, passive tooth bar; 3, slide plate; 4, line slideway; 5, V-block; 6, hydraulic pressure or pneumatic cylinder; 7, active tooth bar; 8, driven gear; 9, rotating shaft; 10, bearing; 11, bearing block; 12, frame; 13, location-plate; 14, workpiece shelf.

The specific embodiment

Shown in Fig. 1～3; The automatic V-block clamping device of present embodiment comprises power set, driving gear 1, passive tooth bar 2, slide plate 3, line slideway 4 and V-block 5, and the rotating shaft of said power set connects with driving gear 1; Said driving gear 1 meshes with the passive tooth bar 2 of pair of parallel; Said two passive tooth bars 2 each upper surface at its a end are fixedly connected a slide plate 3, and said two slide plates 3 are arranged on the line slideway 4 of pair of parallel, and said line slideway 4 is parallel with passive tooth bar 2; The V-type working face forward surface of each a fixing V-block 5, two V-block 5 is right on said two slide plates 3.The power set of the utility model can be motor with rotating function etc.

In the present embodiment; Said power set comprise hydraulic pressure or pneumatic cylinder 6, active tooth bar 7, driven gear 8, rotating shaft 9, bearing 10, bearing block 11 and frame 12; Said hydraulic pressure or pneumatic cylinder 6 are fixed on the frame 12, and the piston rod of said hydraulic pressure or pneumatic cylinder 6 connects with an end of active tooth bar 7, said active tooth bar 7 and driven gear 8 engagements; Said driven gear 8 connects with rotating shaft 9; The outer surface of said rotating shaft 9 is provided with bearing 10, and said bearing 10 is outside equipped with bearing block 11, and said bearing block 11 is fixed on the frame 12.

For guaranteeing the engagement of active tooth bar 7 and driven gear 8, a side of said active tooth bar 7 is provided with location-plate 13, and said location-plate 13 is with initiatively tooth bar 7 is parallel and movable chimeric, and said active tooth bar 7 can slide along location-plate 13.

For ease of V-block 5 clamping work pieces; Said frame 12 and said line slideway 4 also are provided with workpiece shelf 14 on the parallel and side near said V-block 5; The trend of the V-shaped and V-type in the upper end of said workpiece shelf 14 is parallel with said line slideway 4, is in the working region of said V-block 5 with the horizontal center line of the tangent circle of said workpiece shelf 14 upper end V-types.
