Abstract

The utility model relates to a bidirectional clamping cylinder, which comprises a base; a cylinder is fixed at the rear end of the base; a right-angle workbench is fixed at the front end of the base; the cylinder is connected with a movable block through a guide shaft; a clamping arm is hinged at the front end of the movable block through a first pin shaft; the front end of the clamping arm takes the shape of a right-angle hook; an end surface is disposed at the end of the hook; an inside surface is disposed on the inner side of the hook; a long hole is arranged on the clamping arm below the first pin shaft; a transverse shaft is positioned in the long hole; both ends of the transverse shaft are positioned in sliding grooves on both sides of the base; the front end of a piston rod matched with the cylinder is hinged with the clamping arm through a second pin shaft; a stop block is fixed on the piston rod, and is positioned on the front part of the movable block. The bidirectional clamping cylinder has the advantages of simple integral structure, flexible and reliable motion and small occupied space.

Description

Two-way clamping cylinder

Technical field

The utility model relates to a kind of two-way clamping cylinder, is mainly used in rectangular-shaped workpiece is carried out two-way clamping.

Background technology

Cylinder clamping mechanism can not accomplish two-way clamping to rectangular-shaped workpiece when clamping at present, promptly can not accomplish vertical and laterally clamping simultaneously, when clamping as the needs two-way simultaneous, must utilize two groups of clamp mechanism, complex structure, and it is big to take up room, troublesome poeration.

Summary of the invention

The purpose of this utility model provides the two-way clamping cylinder that a kind of simple in structure, reliable in action, the I that takes up room two-way simultaneous clamp, and overcomes the deficiencies in the prior art.

Two-way going up of the present utility model clamps cylinder, and pedestal is arranged, and is fixed with cylinder in the rear end of pedestal, and the front end of pedestal is fixed with rectangular-shaped workbench; Cylinder links to each other with movable block by the axis of guide, is hinged with clamp arm at the front end of movable block by first bearing pin, and the clamp arm front end is at right angles hook-shaped, and there is end face the termination of hook, and there is medial surface the inboard; On the clamp arm slotted hole is being arranged below first bearing pin, transverse axis is positioned at slotted hole, and the two ends of transverse axis are positioned at the chute of both sides on the pedestal; Hinged with the piston rod front end that cylinder matches by second bearing pin and clamp arm; Be fixed with block on piston rod, block is positioned at the front side of movable block.

Two-way clamping cylinder of the present utility model, when piston rod moves forward, the promotion clamp arm moves forward, clamp arm is that rotate at the center with first bearing pin simultaneously, make the front end of clamp arm turn to the top, movable block also moves forward along the axis of guide thereupon, when piston rod was mobile backward, clamp arm was that rotate at the center with first bearing pin, makes the front end of clamp arm turn to the below, end face is pressed on the rectangular-shaped workpiece, form vertical the clamping, piston rod moves after continuing then, and the medial surface of clamp arm is leaned against on the workpiece, form laterally and clamp, movable block is stirred thereupon by block and is moved behind the axis of guide, has realized the purpose of two-way clamping, and overall structure is simple, flexible movements are reliable, do not take than large space.

The specific embodiment

As shown in Figure 1, 2, 3: 1 is pedestal, by bolting cylinder 9 is arranged in the rear end of pedestal 1, and the front end of pedestal 1 has rectangular-shaped workbench 4 by bolting.

It is movable block that the upper fixed of cylinder 9 has two parallel axis of guides 8,7, the hole that matches with the axis of guide 8 is arranged on the movable block 7 and is enclosed within on the axis of guide 8, and movable block 7 can be moved with respect to the axis of guide 8.

Front end at movable block 7 is hinged with clamp arm 5 by first bearing pin 6, and clamp arm 5 front ends are at right angles hook-shaped, and there is end face 14 termination of hook, and there is medial surface 15 inboard.

On the clamp arm 5 slotted hole 13 is being arranged below first bearing pin 6, transverse axis 3 is positioned at slotted hole 13, and the two ends of transverse axis 3 are positioned at the chute 2 of both sides on the pedestal 1, slide block can be housed between transverse axis 3 and the chute 2 be convenient to slide.

Hinged with clamp arm 5 with piston rod 11 front ends that cylinder 9 matches by second bearing pin 10; Be fixed with block 12 on piston rod 11, can be structure as a whole between block 12 and the piston rod 11, also can be threaded, block 12 is positioned at the front side of movable block 7.

By pedestal this mechanism is installed on the frame, cylinder 9 joins with pneumatic means, when rectangular-shaped workpiece 16 places workbench 4 fooled piston rods 11 to move forward, promoting clamp arm 5 moves forward, clamp arm 5 is that rotate at the center with first bearing pin 6 simultaneously, make the front end of clamp arm 5 turn to the top, movable block 7 is also thereupon along the axis of guide 8 reaches, when piston rod 11 is mobile backward, clamp arm 5 is that rotate at the center with first bearing pin 6, make the front end of clamp arm 5 turn to the below, end face 14 is pressed on the rectangular-shaped workpiece 16, forms vertically to clamp, move after piston rod 11 continues then, the medial surface 15 of clamp arm 5 is leaned against on the workpiece 16, form laterally clamping, movable block 7 is stirred thereupon by block 12 and is moved behind the axis of guide 8, realized the purpose of two-way clamping, overall structure is simple, and flexible movements are reliable, does not take than large space.
