Abstract
The utility model relates to a pneumatic horizontal-pushing positioning bidirectional clamping device, which belongs to clamping devices among welding fixtures. A double-guide-post cylinder is connected with a welding support fixedly, a left hinge plate and a right hinge plate of the welding support are respectively and flexibly connected with a left rocker arm and a right rocker arm to form a left fixed hinge and a right fixed hinge, connecting plates are respectively and flexibly connected with a left two-hole hinge plate and a right two-hole hinge plate to form a first left movable hinge and a first right movable hinge, the left two-hole hinge plate and the right two-hole hinge plate are respectively and flexibly connected with the left rocker arm and the right rocker arm to from a second left movable hinge and a second right movable hinge, a left clamping block is connected with the left rocker arm fixedly, a right clamping block is connected with the right rocker arm fixedly, and a positioning pin component is fixed onto the connecting plates. The pneumatic horizontal-pushing positioning bidirectional clamping device has the advantage that the clamping device is novel in structure and capable of smartly and flexibly realizing three functions including positioned pushing and simultaneous bidirectional reverse clamping functions within a narrow space and under strict weight requirement.
Description
Technical field
The utility model belongs to the clamping device in the weld jig, refers in particular to adopt a cylinder can realize the device of horizontal sliding location, two-way clamping.
Background technology
In the positioning clamping device of in weld jig, using always; horizontal sliding location and clamping function will realize with 2 to 3 cylinders usually; the agency cost height; it is big to take up room; running into the positioning clamping device space through regular meeting in weld jig is restricted; and for mechanism's weight strict requirement is arranged, existing like this positioning clamping device just can not adapt to requirements of one's work.
Summary of the invention
The utility model provides a kind of pneumatic horizontal sliding positioning bidirectional clamping device, to solve the problem that existing positioning clamping device takes up room greatly, weight is big.The technical scheme that the utility model is taked is: two guide pillar cylinders are fixedlyed connected with the welding bearing, limited block is fixedlyed connected with two guide pillar cylinders, left flap in the welding bearing, right flap respectively with left rocking arm, right rocking arm flexibly connects the back and forms left fixed hinge and right fixed hinge, connecting plate respectively with left diplopore flap, right diplopore flap flexibly connects the back and forms left hinges one and right hinges one, left side diplopore flap, right diplopore flap respectively with left rocking arm, right rocking arm flexibly connects the back and forms left hinges two and right hinges two, and left clamp is fixedlyed connected with left rocking arm; Right clamp is fixedlyed connected with right rocking arm; Pin assembly is fixed on the connecting plate, left limit piece two in the left limit assembly is fixedlyed connected with left rocking arm, left limit piece one is fixedlyed connected with connecting plate, right limit piece two in the right limit assembly is fixedlyed connected with connecting plate, right limit piece one is fixedlyed connected with right rocking arm, and left locating piece, right locating piece are fixedlyed connected with connecting plate respectively.
Good effect of the present utility model is a novel structure, a kind of novel pneumatic propelling positioning bidirectional of single cylinder clamping device is provided, can ingeniously be implemented in interior with the strict weight of small space flexibly requires down, finish that product advances in the location and 2 oppositely clamp three functions simultaneously, effect is very good.

The specific embodiment
Two guide pillar cylinders 18 are fixedlyed connected with welding bearing 1, limited block 19 is fixedlyed connected with two guide pillar cylinders, left flap 101 in the welding bearing 1, right flap 102 respectively with left rocking arm 10, right rocking arm 9 flexibly connects the back and forms left fixed hinge 17 and right fixed hinge 2, connecting plate 20 respectively with left diplopore flap 15, right diplopore flap 4 flexibly connects the back and forms left hinges 1 and right hinges 1, left side diplopore flap 15, right diplopore flap 4 respectively with left rocking arm 10, right rocking arm 9 flexibly connects the back and forms left hinges 2 16 and right hinges 23, and left clamp 11 is fixedlyed connected with left rocking arm 10; Right clamp 8 is fixedlyed connected with right rocking arm; Pin assembly 21 is fixed on the connecting plate 20, left limit piece 2 1302 in the left limit assembly 13 is fixedlyed connected with left rocking arm 10, left limit piece 1 is fixedlyed connected with connecting plate 20, right limit piece 2 602 in the right limit assembly 6 is fixedlyed connected with connecting plate 20, right limit piece 1 is fixedlyed connected with right rocking arm 9, and left locating piece 12, right locating piece 7 are fixedlyed connected with connecting plate 20 respectively.
Operation principle: the cylinder original position is the cylinder rod withdrawal, during work: the piston rod of two guide pillar cylinders 18 stretches out, drive connecting plate 20, pin assembly 21, left side locating piece 12, right locating piece 7 downward translations, connecting plate 20 drives left hinges 1 simultaneously, right hinges one 5 downward translations, rotate around hinges point respectively, utilize lever principle, the hinges point of left side hinges 2 16 and the left rocking arm 10 of the corresponding again promotion of hinges point of right hinges 23, right rocking arm 9 rotates around each hinge point of left fixed hinge 17 and right fixed hinge 2, up to left rocking arm 10, left limit piece 2 1302 on the right rocking arm 9, the right limit piece 2 602 corresponding left limit pieces 1 that bump against on the connecting plate 20, right limit piece 1, the rotation and the translation motion of whole linkage stop.Left side locating piece 12, right locating piece 7, pin assembly 21 accurate in locating are to product, and left clamp 11, right compact heap 8 clip on the product accurately.At this moment, left hinges 2 16, right hinges 23 corresponding 1601,301 positions that turn to are referring to Fig. 4; Left side hinges 1 and right hinges 1 rotate to 1401,501 positions, referring to Fig. 4, finish the one-time positioning clamping process.Two guide pillar cylinder 18 piston rods withdrawals after operation element is finished, original position is got back in the reverse translation rotation of mechanism, has finished opening procedure one time, has so just finished a complete working cycles.
