In order to achieve the above object, the utility model provides a spring clamp, including the relative drive arrangement who sets up a pair of clamping jaw and the drive clamping jaw that the structure is the same, the clamping jaw includes the grip block of rectangular shape be equipped with a plurality of clamping parts on the clamping face of grip block, a plurality of clamping parts are setting up along grip block length direction equipartition, the clamping face of clamping part is the recess shape, the clamping part is inlayed and is had soft strip.

Further, the clamping part is a V-shaped groove.

Further, the clamping part is for including a center block with establish the limit piece in center block both sides respectively, the surface of limit piece is an inclined plane, the inclined plane of two limit pieces all is towards middle center block, be equipped with the clearance between limit piece and the center block, it has to inlay in the clearance soft strip.

Furthermore, a clamping groove is formed in the side end face of the side block on the inner side of the gap, and the soft strip is clamped in the clamping groove.

Furthermore, the driving device is an air cylinder, and the clamping jaw is fixedly connected with the output end of the air cylinder through a connecting plate

Further, the soft strips are polyurethane round strips.

The utility model has the advantages that: the cylinder drive clamping jaw opens, after contracting again with between two clamping jaws of spring centre gripping, the clamping jaw in design V type groove can also carry out automatic position compensation to the spring of centre gripping like this, can automatic centering to soft strip also can carry out position compensation, can protect the spring surface, avoids being pressed from both sides the wound by the clamping jaw, and clamping part on the clamping jaw is the comb teeth form of alternation and arranges simultaneously, can add the cross-section size that extends the centre gripping spring, satisfies the centre gripping needs of the spring of equidimension not. The utility model discloses strong adaptability, the centre gripping is stable, and can not harm the spring surface.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, wherein it is noted that, in the description of the invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular manner, and therefore should not be construed as limiting the present invention. The terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1 to 5, the utility model provides a spring clamp, including relative a pair of clamping jaw 1 that sets up the structure the same, clamping jaw 1 is the grip block 2 of rectangular shape, integrated into one piece processing has a plurality of clamping parts 3 on the clamping face of grip block 2, equidistant equipartition setting on a plurality of clamping parts 3 along the length direction of grip block 2, every clamping part 3 includes a center block 4 and two limit pieces 5, two limit pieces 5 are established respectively in 4 both sides of center block, the surface of limit piece 5 is an inclined plane, the inclined plane of limit piece 5 all is towards middle center block 4. The surface of the central block 4 is a V-shaped groove, and the groove surface of the V-shaped groove of the central block 4 and the inclined surface of the side block 5 on the same side are on the same plane. Such a central block 4 and two side blocks 5 form integrally a V-shaped groove with a discontinuity in the middle. The clamping jaw 1 is made of high-hardness aluminum alloy.

A gap 6 is arranged between the edge block 5 and the central block 4, a clamping groove is formed in the side end face of the edge block 5 inside the gap 6, the clamping groove is a V-shaped groove, a cylindrical soft strip 7 is embedded in each gap 6, the upper end face of each soft strip 7 protrudes out of the surfaces of the central block 4 and the edge block 5, and the soft strip 7 is preferably made of a polyurethane round strip.
