Abstract
The utility model relates to a machine tool part, in particular to an expansion clamp head. The expansion clamp head comprises a hollow cylindrical clamp head body, wherein the clamp head body is provided with a plurality of contraction joints along the long direction of the clamp head body; the contraction joints are divided into two groups, namely a first group of contraction joints and a second group of contraction joints respectively; the first group of contraction joints and the second group of contraction joints are arranged at intervals; each of the first group of contraction joints is open at one end of the clamp head body and is provided with a connecting part at the other end of the clamp head body; and each of the second group of the contraction joints is provided with a connecting part at one end of the clamp head body and is open at the other end of the clamp head body. The expansion clamp head with the structure has the advantage of good clamping effect.
Description
Technical field
The utility model relates to machine tool component, particularly relates to a kind of folder chuck that rises.
Background technology
The folder chuck extensive use on lathe of rising, it has the columniform chuck body of hollow, the chuck body have a plurality of along its long to shrinkage joint; In the prior art, shrinkage joint is at chuck body one end opening, have the coupling part at the other end of chuck body, and a plurality of shrinkage joints all are the same; That is to say; All shrinkage joints are openings at the same end of chuck body, and the other end all has the coupling part, and such folder chuck that rises has and adds the shortcoming of holding weak effect.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned shortcoming, provide a kind of simple in structure, add the folder chuck that rises of holding better effects if.
The technical scheme of the utility model is achieved in that a kind of folder chuck that rises, and comprises the columniform chuck body of hollow, the chuck body have a plurality of along its long to shrinkage joint; It is characterized in that; Described shrinkage joint is divided into two groups, is respectively first group of shrinkage joint and second group of shrinkage joint, and first group of shrinkage joint and second group of shrinkage joint are spaced; Described first group of shrinkage joint is at chuck body one end opening; The other end at the chuck body has the coupling part, and described second group of shrinkage joint is at chuck body one end the coupling part to be arranged, and is opening at the other end of chuck body.
The beneficial effect of the utility model is: the folder chuck that rises of this spline structure has and adds the advantage of holding better effects if.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1, chuck body 2, first group of shrinkage joint 3, second group of shrinkage joint 4, an end 5, the other end 6, coupling part.
Specific embodiments:
Below in conjunction with accompanying drawing the utility model is further described.
Of Fig. 1, a kind of folder chuck that rises comprises the columniform chuck body 1 of hollow; Chuck body 1 have a plurality of along its long to shrinkage joint, it is characterized in that described shrinkage joint is divided into two groups; Be respectively first group of shrinkage joint 2 and second group of shrinkage joint 3; First group of shrinkage joint 2 and second group of shrinkage joint 3 are spaced, and described first group of shrinkage joint 2 is at chuck body one end 4 openings, at the other end 5 of chuck body coupling part 6 are arranged; Described second group of shrinkage joint 3 is at chuck body one end 4 coupling part 6 to be arranged, and is opening at the other end 5 of chuck body.
The coupling part that is to say two groups of shrinkage joints is respectively at the not same end of chuck body, and the other end is an opening.
