Abstract
The invention discloses a spring chuck for turning use and aims to solve the problem that shafts are inconvenient to clamp in the prior art. The spring chuck comprises a machine tool spindle, a hollow chuck body, and a collet chuck having an open channel. The open channel axially extends from the head of the collet chuck to the middle of the collet chuck. The chuck body is fixed to a machine tool. The collet chuck is disposed inside the chuck body. The spring chuck for turning use further comprises a connecting sleeve whereby the machine tool spindle is connected with the collet chuck; the connecting sleeve is disposed inside the chuck body; a sliding sleeve is connected to the head of the collet chuck; a piston is connected outside the siding sleeve; the sliding sleeve is provided with a conical face used for compressing the collet chuck; the piston is connected with the chuck body in a sleeving manner; the open channel of the collet chuck is filled with an elastic rubber layer. The spring chuck for turning use 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 turning 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 turning collet, to solve the problem of prior art axis class clamping workpiece inconvenience.
For addressing the above problem, turning collet in this programme, comprise the clamp of machine tool chief axis, hollow and be provided with the collet chuck of open slot, open slot extends axially to collet chuck middle part from collet chuck head, clamp and lathe are fixed, collet chuck is positioned at clamp inside, the adapter sleeve that also comprises connecting machine tool main shaft and collet chuck, adapter sleeve is positioned at clamp, collet chuck head is connected with sliding sleeve, and sliding sleeve is externally connected with piston, and sliding sleeve is provided with for compressing the conical surface of collet chuck, piston socket clamp, is filled with elastic rubber layer in the open slot of collet chuck.
Compared with prior art, advantage of the present invention is: under duty, when piston outwards moves away from machine tool chief axis, drive sliding sleeve outwards to move, the conical surface compression cylinder mounting board clamping of workpieces of sliding sleeve; When piston leans on while inwardly moving into machine tool chief axis, drive sliding sleeve inwardly to move, the conical surface of sliding sleeve leaves collet chuck, and collet chuck unclamps workpiece; Collet chuck is annular, and workpiece is stressed evenly, and clamping angle is adjusted automatically, in addition, in the open slot of collet chuck, is filled with elastic rubber layer, can prevent that the impurity such as iron filings from entering open slot, affects workpiece positioning precision.To sum up, the present invention is simple in structure, processing ease, convenient mounting and clamping.
Further, between adapter sleeve and machine tool chief axis, be provided with the bolt that regulates adapter sleeve axial location, can adjust the axial distance of adapter sleeve and machine tool chief axis by turn bolt, and then regulate the shrinkage amplitude of collet chuck.
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 collet embodiment for turning of the present invention.
The specific embodiment
Shown in Fig. 1, turning collet in the embodiment of the present invention, comprise machine tool chief axis, the clamp of hollow and the collet chuck 5 that is provided with open slot, open slot is from collet chuck 5 head shaft to extending to collet chuck 5 middle parts, clamp and lathe are fixed, collet chuck 5 is positioned at clamp inside, the adapter sleeve 2 that also comprises connecting machine tool main shaft and collet chuck 5, adapter sleeve 2 is positioned at clamp, collet chuck 5 heads are connected with sliding sleeve 4, sliding sleeve 4 is externally connected with piston 3, sliding sleeve 4 is provided with for compressing the conical surface of collet chuck 5, piston 3 socket clamps, in the open slot of collet chuck 5, be filled with elastic rubber layer, between adapter sleeve 2 and machine tool chief axis, be provided with the bolt 1 that regulates adapter sleeve 2 axial locations.
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)
