Abstract
The utility model provides a three-jaw clamping device of an octagonal nut, and belongs to the field of fastening of octagonal nuts. The three-jaw clamping device comprises a three-jaw chuck, wherein a first clamping block, a first clamping block and a third clamping block are fixedly arranged on three jaws of the three-jaw chuck respectively, and the inner side face of the first clamping block, the inner side face of the second clamping block and the inner side face of the third clamping block are respectively provided with a groove matched with the outer contour of the octagonal nut. The three-jaw clamping device is simple in structure and convenient to operate, the octagonal nut can be clamped after being placed in a tool, machining efficiency is high, machining accuracy of products is also high, and labor intensity is lowered.
Description
Technical field
The utility model relates to the fastener of nut in the time of machining screw from all directions, specifically the three-jaw clamping device of all directions nut.
Background technology
At present, from all directions nut when machining screw, need to use chuck to step up, still on lathe, in the time that all directions nut is carried out to centering, need to repeatedly adjust accurately centering, and process more complicated, be difficult to ensure concentricity, working (machining) efficiency is low, has virtually increased labour intensity.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, and a kind of three-jaw clamping device of all directions nut of simple to operate, the machining accuracy that can improve product is provided.
The utility model solves the technical scheme that its technical problem adopts:
The three-jaw clamping device of nut from all directions, comprise scroll chuck, on three pawls of described scroll chuck, be fixed with respectively the first clamp, the second clamp, the 3rd clamp, the medial surface of described the first clamp, the second clamp, the 3rd clamp is respectively equipped with the groove matching with the outline of all directions nut.
Detailed, the shape of the groove of described the first clamp medial surface is with match in the first side and second side of nut from all directions, the shape of the groove of the second clamp medial surface matches with the 4th side and the 5th side of all directions nut, and the shape of the groove of the 3rd clamp medial surface is with match in the 6th side, heptalateral face and the 8th side of nut from all directions.
Detailed, described the first clamp, the second clamp, the 3rd clamp are bolted respectively on three pawls that are arranged on scroll chuck.
Compared with prior art, the beneficial effect producing is the three-jaw clamping device of all directions of the present utility model nut:
The utility model is simple in structure, easy to operate, and all directions nut is put into after frock and can be clamped nut from all directions, and working (machining) efficiency is high, and the machining accuracy of product is also high simultaneously, has reduced labour intensity.
