The specific embodiment
Below in conjunction with accompanying drawing, describe in detail:
As shown in Figure 1, guide holder 17 and U-shaped seat 15 are arranged on base 16 by bolt, the endoporus matched in clearance of guide pillar 2 and guide holder 17, guide pillar 2 is fixing by push pedal 1 and wedge 3 through guide holder 17, forms quadrilateral structure, and this quadrilateral structure can horizontally slip along the endoporus of guide holder 17, wedge 3 right half parts are wedge structure, wedge shape inclined-plane and horizontal direction angle are 8 ~ 20 °, as the angle of lock on wedge shape inclined-plane, form the self-locking structure on wedge shape inclined-plane.In the U-lag of U-shaped seat 15, mounting and adjusting pedestal 5, adjusting seat 5 thickness are identical with U-shaped seat thickness 15, adjusting seat 5 left ends arrange two bar-shaped troughs, make it can be along U-lag horizontal adjustment position, by two bolts, adjusting seat 5 is fastened on base 16, aligning V piece 9 is arranged on above adjusting seat 5, spacing pin 8 and V piece rotating shaft 10 are vertically mounted on adjusting seat 5 right-hand members and pass aligning V piece 9, a pivot hole and an arc groove structure of aligning V piece 9 have guaranteed that aligning V piece 9 both can be around V piece rotating shaft 10 rotations, be subject to again the restriction of spacing pin 8, two identical clamp arms 11 of the symmetrical installation in aligning V piece 9 left and right sides, clamp arm 11 mid portions are arranged on U-shaped seat 15 by clamp arm rotating shaft 7, the pivot hole of clamp arm 11 and clamp arm rotating shaft 7 matched in clearance, guaranteed that clamp arm 11 can be around clamp arm rotating shaft 7 rotations, on clamp arm 11 left end length directions, it is U-lag structure, on clamp arm 11 left end thickness directions, have through hole, bearing pin 4 is through through hole and bearing 14 inner rings, bearing 14 is arranged in U-lag, two spring abutments 13 of at right angle setting between clamp arm 11 upper surface bearing pins 4 and clamp arm rotating shaft 7, two 13 of spring abutments are installed reset tension spring 6, clamp arm 11 right-hand member crank arm structures and aligning V piece 9 have guaranteed 4 clampings of workpiece 13.
Push pedal 1 can adopt hydraulic cylinder, the element such as pneumatic cylinder or electric cylinder produces push pull maneuver, when low order end (being position shown in Fig. 2) is shifted in push pedal 1 onto, wedge 3 moves right, its wedge shape inclined-plane presses on bearing 14, promote two clamp arms 11 around clamp arm rotating shaft 7 rotations, two clamp arm 11 right-hand members inwardly rotate, and coordinate with aligning V piece 9 workpiece 12 clampings, because the Self-locking angle on wedge 3 wedge shape inclined-planes is less, bearing 14 can obtain very large thrust, the clamping force of workpiece 12 is large, if remove the thrust of push pedal 1 after clamping, self-locking action due to wedge 3 wedge shape inclined-planes, wedge 3 can not be moved to the left, workpiece 12 is reliably locked, when high order end (being position shown in Fig. 1) is moved in push pedal 1 to, wedge 3 is to left movement, and separated with bearing 14, reset tension spring 6 is inwardly drawn clamp arm 11 left ends over to one's side, under reset tension spring 6 pulling force effects, clamp arm 11 is around clamp arm rotating shaft 7 rotations, two clamp arm 11 right-hand members outwards open, workpiece 12 unclamps.
When workpiece 12 loses bowlder, in workpiece 12 clamping process, clamp arm 11 right-hand member crank arm structures press workpiece 12, workpiece 12 compresses aligning V piece 9, due to the skew of workpiece 12 shapes or center line, aligning V piece 9 is around V piece rotating shaft 10 rotations, and after balance, workpiece 12 still can reliable grip.
