Abstract
The invention discloses an eccentric collet chuck which aims at solving the problem that axial workpieces are inconvenient to clamp in the prior art. The eccentric collet chuck comprises a hollow clamp body and a collet which is provided with an open groove; the open groove axially extends to the middle of the collet from the head portion of the collet; the collet is matched with the empty chamber of the clamp body; the end portion of the clamp body is provided with the inner conical surface which is used for compressing the collet; the eccentric collet chuck also comprises a rotary shaft and a connecting block; the rotary shaft is arranged on the side wall of the clamp body; the connecting block moves along the empty chamber of the clamp body and is connected with the collet and the rotary shaft; the end portion of the rotary shaft is provided with an eccentric block; the rotary shaft is embedded into the connecting block through the eccentric block; the open groove of the collet is filled with elastic rubber layers. The eccentric collet 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 centering type collet.
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 centering type collet, to solve the problem of prior art axis class clamping workpiece inconvenience.
For addressing the above problem, centering type collet 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 comprise that rotating shaft that clamp sidewall is provided with moves with along clamp cavity and be connected the contiguous block of collet chuck, rotating shaft, roller end is provided with eccentric block, rotating shaft is chimeric by eccentric block and contiguous block, 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, rotating shaft is rotated, by eccentric block, drive contiguous block to move up and down along clamp cavity, thereby drive collet chuck to move up and down along clamp cavity, realize that collet chuck unclamps or the action of clamping work pieces, the present invention is simple in structure, processing ease; 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, between contiguous block and collet chuck, be threaded, replacing collet chuck for convenience detach.
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 centering type collet embodiment of the present invention.
The specific embodiment
Shown in Fig. 1, centering type collet 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, collet chuck 2 mates with clamp 1 cavity, clamp 1 end is provided with for compressing the inner conical surface of collet chuck 2, also comprise rotating shaft 3 and contiguous block that clamp 1 sidewall is provided with, rotating shaft 3 ends are provided with eccentric block, rotating shaft 3 is chimeric by eccentric block and contiguous block, contiguous block is threaded with collet chuck 2 away from rotating shaft 3 one end, in the open slot of collet chuck 2, is filled with elastic rubber layer.
Under duty, rotating shaft 3 is rotated, and by eccentric block, drives contiguous block to move up and down along clamp 1 cavity, and when eccentric block moves upward, contiguous block moves upward, and drives collet chuck 2 to move upward along clamp 1 cavity, realizes the action that collet chuck 2 unclamps workpiece; When eccentric block moves downward, contiguous block moves downward, and drives collet chuck 2 to move downward along clamp 1 cavity, realizes the action of collet chuck 2 clamping work pieces.
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 centering type collet, 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, and clamp end is provided with for compressing the inner conical surface of collet chuck, it is characterized in that, also comprise that rotating shaft that clamp sidewall is provided with moves with along clamp cavity and be connected the contiguous block of collet chuck, rotating shaft, roller end is provided with eccentric block, and rotating shaft is chimeric by eccentric block and contiguous block, in the open slot of collet chuck, is filled with elastic rubber layer.
2. centering type collet according to claim 1, is characterized in that, between contiguous block and collet chuck, is threaded.
