Abstract

The utility model discloses a vertical pneumatic two-way clamping device which belongs to a welding clamp. A large welding support is fixed on working table board, and a cylinder and a base are respectively and fixedly connected with the large welding support; a support seat and a large limiting seat are respectively and fixedly connected with the support; a small limiting seat is fixed on the support seat; a Y-shaped connecting block is fixedly connected with the cylinder through a nut; two connecting plates are flexibly connected on the connecting block through one ends of four groups of small hinged shaft, a small gasket and a small-opening pin, and the other ends are respectively connected on a left swinging arm and a right swinging arm; and the left swinging arm and the right swinging arm are flexibly connected on the support seat through a large hinged shaft, a large gasket and a large-opening pin. The vertical pneumatic two-way clamping device has the advantages that the structure is novel, the occupied plane space is minimum in the opening state of the clamp, loading and unloading the workpieces manually is facilitated, and simultaneous clamping of a product in larger range in two opposite directions can be realized.

Description

The two-way clamping device of vertical pneumatic

Technical field

The utility model relates to a kind of weld jig, and being applicable in the weld jig has the place that clamps demand simultaneously to product at opposite both direction, especially narrow and small, the zone of putting difficulty, space.

Background technology

Pneumatics clamping device commonly used can only be realized the unidirectional clamping of a cylinder in weld jig, and occupation of land space in the plane is bigger, and the area of corresponding anchor clamps is also bigger.In weld jig, run into clamping space and be restricted through regular meeting, and the situation that need when opposite both direction in a big way, clamp simultaneously.

Summary of the invention

The utility model provides a kind of vertical pneumatic two-way clamping device, with the problem that area is big, clamping space is restricted that solves anchor clamps.

The technical scheme that the utility model is taked is: weld bearing greatly and be fixed on the work top, cylinder, bearing are fixedlyed connected with big welding bearing respectively, and supporting seat, big limit base are fixedlyed connected with bearing respectively, and little limit base is fixed on the supporting seat; "

" font, its lower end be threaded with cylinder rod on the cylinder 14 and by nut 12 back ofs the body tightly with anti-rotation, the upper end flexibly connects formation fixed

hinge

103 and 107 in back with two connecting plates 13 by small hinge axle 10, small washer 8, little split pin 9; The other end of two connecting plates 13 flexibly connects the back by small hinge axle, small washer, little split pin and left rocking arm, right rocking arm and

forms hinges

101 and 105; Bearing 19, Connection Block 20 are fixed on the big welding bearing 21 by screw and pin respectively; Left side rocking arm 2 and right Rocker arm 4 flexibly connect on supporting seat 20 by big hinge axis 5, large washer 7, big split pin 9, form fixed hinge 109, between left side rocking arm 2, right Rocker arm 4 and the supporting seat 20 no oily thrust washer 6 is housed all, guarantee lubricated the time, can adjust the tram of centering left side rocking arm 2, right Rocker arm 4 and two connecting plates 13 and contiguous block 11.Five hinge axis 101,103,105,107,109 of Xing Chenging will guarantee parallel to each other like this.

Two limited blocks 16 are separately fixed on the little limit base 17 and on the big limit base 18, in order to the lower limit to left rocking arm 2 and right Rocker arm 4; Two other limited block 16 is separately fixed on left rocking arm 2 and the right Rocker arm 4, is turned to bit position and protects rocking arm directly not clashed into and damage in order to restriction left and right sides rocking arm.

During this device work: in cylinders retract, the mechanism opening state is gone up part down, cylinder 14 is received the working signal indication, cylinder rod stretches out, drive contiguous block 11 upwards translations, contiguous block 11 drives 103 of two connecting plates 13, the translation that makes progress of 107 fixed hinges, corresponding promotion hinges 101 and 105 rotates around fixed hinge 109, utilize lever principle, the left rocking arm 2 of corresponding again promotion, right Rocker arm 4 rotates around fixed hinge 109, up to left rocking arm 2, limited block 16 on the right Rocker arm 4 is corresponding to bump against big limit base 18, limited block 16 on the little limit base 17, the rotation and the translation motion of whole linkage stop, compact heap 1, compact heap 3 is pressed onto on the product, at this moment, fixed hinge 103,107 correspondingly move to 104,108 positions,

hinges

101 and 105 rotates to 102,106 positions, cylinder 14 are sent to stretch out and are stopped the signal of telecommunication, finish clamping process one time.In like manner, cylinder 14 is received the indication of return signal, the cylinder rod withdrawal, and mechanism's reverse flip, up to being withdrawn into zero stroke, cylinder 14 sends return and stops the signal of telecommunication, has finished opening procedure one time, has so just finished a complete working cycles.
