Abstract
Provided is a double-rocker clamp. The double-rocker clamp comprises a work table, a support, a spring collet, a spring collet handle, an adjusting screw nut, adjusting gaskets, a fastening screw nut, a clamping rod, a connecting rod set and a handle. The support is fixed on the work table, a spring collet embossment is arranged on the lower end of the spring collet, the spring collet handle is arranged on the upper end of the spring collet and of a round steel bar, and threads are arranged on the upper end of the round steel bar. The clamping rod is made of a strip-shaped flat steel bar, and a strip-shaped clamping rod moving groove is arranged in the middle of the clamping rod. The spring collet handle penetrates through the clamping rod moving groove and is fixed on the clamping rod through the adjusting screw nut and the fastening screw nut, and the adjusting gaskets are arranged among the adjusting screw nut, the fastening screw nut and the clamping rod. By adopting the structure, the double-rocker clamp can not generate too much pressure on workpieces to damage the workpieces, and compacting and loosening are both convenient.
Description
Technical field
The utility model relates to the instrument in a kind of cold processing technique field, particularly a kind of double rocking lever anchor clamps that are used for fixing processing parts.
Background technology
When our processing parts, the part that needs to prepare first processing is fixed, and general clamping device is because the spring element on not have axially clamping often the usually very large axial clamping force of generation, easily causes deformation of products, and clamping and unclamp inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of double rocking lever anchor clamps are provided, and it comprises support section, collet segment and shaft portion.
Described support section comprises: workbench, bearing, bearing stile, the flat limit of bearing, and worktable upper surface is a plane, and bearing is the steel construction of one " 7 " font, and bearing is comprised of bearing stile and the flat limit of bearing, and the flat limit of the bearing of bearing is fixed on the workbench.
Described collet segment comprises: collet, the collet projection, the collet handle, adjusting nut, regulate pad, locknut, clamping bar, the clamping bar shifting chute, there is the collet projection lower end of collet, there is the collet handle upper end of collet, the collet handle is the screwed circular steel bar in upper end, clamping bar is that flat steel of strip made, the centre has strip clamping bar shifting chute, the collet handle passes the clamping bar shifting chute and passes through adjusting nut, locknut is fixed on the clamping bar, at adjusting nut, the adjusting pad is housed between locknut and the clamping bar.
Described shaft portion comprises: first connecting rod, second connecting rod, third connecting rod, handle, the right-hand member of clamping bar is fixed on the left end of first connecting rod, the right-hand member hinge of first connecting rod is connected on the bearing stile of bearing, the lower end hinge of third connecting rod is connected on the flat limit of bearing of bearing, the upper end of third connecting rod is installed with handle, and the two ends of second connecting rod are connected on first connecting rod, the third connecting rod by hinge respectively.
The utility model compared with prior art has following features: first connecting rod, second connecting rod, third connecting rod form connection rod set, workpiece is placed on the appropriate location of workbench, moving handle, connection rod set drives clamping bar and moves up and down, collet can be pushed down workpiece in the time of downwards, after machining, moving handle, connection rod set drives clamping bar and moves up and down, collet can unclamp workpiece in the time of upwards, the new shape of this practicality can not produce too large pressure so that defective work piece to workpiece, and compression is unclamped all very convenient owing to adopting above structure.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
