Abstract

The utility model relates to an assembly chipping tool assembled by 4 groups of chipping tools 1 located by a key and connected by bolts. The utility model can process multiple workpieces by once-through workpiece clamping, improving work efficiency. In the prior art, when the air tongs moving a long-distance at high speed by a support with a steel ball and leading screw assembly, a set screw must be loosend first, then the support must be pushed to a proper location and the set screw must be fastened to withstand the steel ball to compensate the movement. The uility model is characterized in that the support can be pushed to a proper location only by raising the set screw, then press the set screw to the fixed location, thereby completing the once-through stable clamping accurately while saving clamping time and mounting space. The uility model has a long service live, is convenient to mount and easy to popularize.

Utility model content the purpose of this utility model provides a kind of combined type flat-nose pliers, this combined type flat-nose pliers is combined into one many flat-nose pliers, and quick rapidly with clamping workpiece on every flat-nose pliers, positioning accuracy height, the fast moving clamping device of long service life.

The technical solution of the utility model is, a kind of combined type flat-nose pliers, comprise caliper, fixed pincers, moving pincers, movable clamp port, decide jaw and clamping device, fixed pincers are fixed on the caliper by screw, moving pincers are incorporated into caliper with the slide rail activity, should be moving, on the working face of fixed pincers respectively with the fixing movable clamp port and decide jaw of screw attachment, should move on vertical protruding rail of caliper by the jackscrew promotion of clamping device by moving pincers, it is characterized in that: the combined type flat-nose pliers is combined by 2-8 group flat-nose pliers, the caliper both sides of flat-nose pliers, the bottom is provided with positioning spline, the end is provided with positioning spline and screw hole, is connected two sides by caliper between flat-nose pliers and the flat-nose pliers, the positioning spline that positioning spline that the bottom is provided with and end are provided with is linked together by the bolt that is spirally connected in the screw hole of end by the key location again.

Preferably, described positioning spline middle part is an oval-shaped groove, and two ends are rectangular recess, and rectangular recess and oval-shaped groove connect, and are provided with hole, deep gouge in oval-shaped groove.

Preferably, described clamping device is made of jackscrew and bearing, bearing is provided with internal thread hole, jackscrew cooperates with internal thread hole on the bearing, bearing is that both sides are provided with symmetrical step-like cuboid, the stairstepping of bearing both sides cooperates with the caliper of flat-nose pliers, and the two ends, bottom of bearing are provided with boss, is provided with the hemisphere that protrudes the bottom surface in the bearing bottom surface.

The beneficial effects of the utility model are: owing to adopt above-mentioned structure, many flat-nose pliers are combined, No. one time a plurality of workpiece of clamping are processed operation, can increase work efficiency, overcome original bearing and adopted steel ball, jackscrew must at first unclamp jackscrew when being used in combination the fast moving that realizes the big distance of moving pincers, and the push-and-pull bearing is tightened jackscrew again and withstood steel ball to appropriate position then, just can finish the deficiency that once moves, after adopting structure of the present utility model, only need when mobile to carry jackscrew, get final product the push-and-pull bearing to appropriate position, press down jackscrew then to the fixed position, once move promptly to accuse and finish, reduced clamping time, also saved installing space simultaneously than original clamping device, clamping is quick rapidly, the workpiece reliable clamping, positioning accuracy height, long product lifecycle, easy to assembly with flat-nose pliers, have wide range of applications.
