Abstract
The invention discloses a displacement-type spring chuck. The displacement-type spring chuck is used for solving the problem of clamping inconvenience of shaft workpieces in the prior art and comprises a hollow chuck body and a collet chuck with an open slot, the open slot extends from the head of the collet chuck to the middle of the collet chuck, the collet chuck is matched with the cavity of the chuck body, and the end portion of the chuck body is provided with an internal conical surface for compressing the collet chuck. The displacement-type spring chuck also comprises a nut which is arranged outside the collet chuck and threadedly connected with the end portion of the chuck body; an elastic rubber layer is filled inside the open slot of the collet chuck. The displacement-type spring chuck is simple in structure and easy to operate.
Description
Technical field
The present invention relates to the clamping device technical field of Machining of Shaft-type Parts, be specifically related to a kind of displacement spring chuck.
Background technology
When machine tool chief axis working shaft-like part, need the clamping device of axle class special use to its clamping position, at present, often there is following problem in the clamping device that the manufacturing procedure of shaft-like workpiece adopts: in the time of need to carrying out process operation along circumferential a plurality of angles to shaft-like workpiece, because clamping device can not regulate clamping angle, or the structure of adjusting angle is more complicated, makes troubles to operation, reduce working (machining) efficiency.
Summary of the invention
The invention is intended to provide a kind of displacement spring chuck, to solve the problem of prior art axis class clamping workpiece inconvenience.
For addressing the above problem, displacement spring chuck in this programme, the clamp and the collet chuck that is provided with open slot that comprise hollow, open slot extends axially to collet chuck middle part from collet chuck head, collet chuck mates with clamp cavity, clamp end is provided with for compressing the inner conical surface of collet chuck, also comprises the outer nut being connected with clamp end thread of collet chuck, in the open slot of collet chuck, is filled with elastic rubber layer.
Compared with prior art, advantage of the present invention is: under duty, during rotating nut, collet chuck moves in clamp cavity, makes collet chuck contraction clip clamping of workpieces under the effect of clamp inner conical surface; During reversion nut, collet chuck moves outside clamp cavity, and collet chuck opens, and unclamps workpiece, and the present invention is simple in structure, processing ease, convenient mounting and clamping; In open slot, be filled with elastic rubber layer, no matter collet chuck clamping work pieces whether, open slot is all the time in closed state, and having avoided iron filings to enter collet chuck affects clamping precision.
Further, on clamp sidewall, be also provided with support nail, for the axial location of workpiece.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of displacement spring chuck embodiment of the present invention.
The specific embodiment
Shown in Fig. 1, displacement spring chuck in the embodiment of the present invention, the clamp 1 and the collet chuck 2 that is provided with open slot that comprise hollow, open slot is from collet chuck 2 head shaft to extending to collet chuck 2 middle parts, and collet chuck 2 mates with clamp 1 cavity, and clamp 1 end is provided with for compressing the inner conical surface of collet chuck 2, also comprise the outer nut 3 being connected with clamp 1 end thread of collet chuck 2, in the open slot of collet chuck 2, be filled with elastic rubber layer, on clamp 1 sidewall, be also provided with support nail, for the axial location of workpiece.
Under duty, during rotating nut 3, collet chuck 2 moves in clamp 1 cavity, makes collet chuck 2 contraction clip clamping of workpieces under clamp 1 inner conical surface effect; During reversion nut 3, collet chuck 2 moves outside clamp 1 cavity, and collet chuck 2 opens, and unclamps workpiece.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic is not done too much description at this.Should be understood that; for a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
1. a displacement spring chuck, the clamp and the collet chuck that is provided with open slot that comprise hollow, open slot extends axially to collet chuck middle part from collet chuck head, collet chuck mates with clamp cavity, clamp end is provided with for compressing the inner conical surface of collet chuck, it is characterized in that, also comprise the outer nut being connected with clamp end thread of collet chuck, in the open slot of collet chuck, be filled with elastic rubber layer.
2. displacement spring chuck according to claim 1, is characterized in that, is also provided with support nail on clamp sidewall.
