Abstract

The utility model relates to a gas clamp which is used for an automotive industry production line, particularly a clamping work piece which is used for stamping and producing an automotive covering piece and automatically connecting lines. The utility model is composed of a cylinder, a gear, a rack, two swivel arms and a jaw, wherein, the cylinder is engaged with the gear through the rack fixed on the cylinder; the gear A is engaged with the gear B vertically arranged; two swivel arms provided with jaws are fixedly connected respectively with rotating shafts of the gear A and the gear B. The jaw can be opened about 180 DEG, the work piece is taken out with simple operation, and the utility model is processed and used conveniently, etc.

Description

A kind of Gas clamp

The utility model relates to the auto industry production line, specifically is the holding workpiece that is applied to the automatic on line of vehicle cladding element punching production.

At present, in the auto industry stamping line, be used for the clamp that automobile covers the automatic on line of punching production, its jaw is dehisced less than 180 degree, and when the upper and lower motion of caught workpiece vertical direction, clamp needs to move behind axis direction, behind the caught workpiece location, clamp moves forward again, clamps workpiece, and promptly holding action is twice motion.

In order to overcome above-mentioned deficiency, the utility model provides a kind of jaw to dehisce to equal 180 degree, and takes out the simple Gas clamp of workpiece action.

To achieve these goals, the technical scheme that the utility model adopted is: be made up of cylinder, gear, tooth bar, pivoted arm, jaw, wherein cylinder is by fixing the rack and pinion A engagement on it, described gear A meshes with the gear B of vertical placement, and two pivoted arms that have jaw are fixedly linked with gear A, gear B gyroaxis respectively.

The utlity model has following advantage:

1. the motion of holding workpiece is unfettered, simple.Because the utility model adopted rack and pinion drive mechanism, make jaw 180 degree of can dehiscing, can satisfy being held the workpiece work vertically and the requirement of two motions of level, clamp is once finished along two actions that axis moves forward and backward.

2. simple in structure, compact, easy to process; Can change according to the difference of part shape owing to its jaw in addition, easy to use.

Below in conjunction with accompanying drawing the utility model is described in further details.

Fig. 1 is the utility model structural representation.

A kind of Gas clamp, form by cylinder 1, gear 2, tooth bar 3, pivoted arm 4, jaw 5, it is characterized in that: wherein cylinder 1 is by fixing the tooth bar 3 and gear A 21 engagements on it, described gear A 21 meshes with the gear B 22 of horizontal positioned, and two pivoted arms 4 that have jaw 5 are fixedly linked with gear A 21, gear B 22 gyroaxises respectively; Described jaw 5 is replaceable.

Its operation principle is as follows:

As shown in Figure 1, the reciprocating motion of cylinder 1 drives its anterior fixing tooth bar 3 and moves reciprocatingly, and then tooth bar 3 promotion a pair of pitch wheel A21, B22 back and forth rotate around its fixed axis, and driving pivoted arm 4 is done and opened or closing motion.

Claims (2)

1. Gas clamp, form by cylinder (1), gear (2), tooth bar (3), pivoted arm (4), jaw (5), it is characterized in that: wherein cylinder (1) is by fixing the tooth bar (3) and gear A (21) engagement on it, described gear A (21) meshes with the gear B (22) of horizontal positioned, and two pivoted arms (4) that have jaw (5) are fixedly linked with gear A (21), gear B (22) gyroaxis respectively.

2. according to the described Gas clamp of claim 1, it is characterized in that: described jaw (5) is replaceable.
