Embodiment Construction

[0009] according to figure 1 As shown, the displacement spring collet in the embodiment of the present invention includes a hollow collet body 1 and a collet 2 provided with an open groove. The open groove extends axially from the head of the collet 2 to the middle of the collet 2. The collet 2 Match the cavity of the clamp body 1, the end of the clamp body 1 is provided with an inner tapered surface for compressing the collet 2, and also includes a nut 3 threaded on the outside of the collet 2 and the end of the collet 1, and an opening groove of the collet 2 The inside is filled with an elastic rubber layer, and the side wall of the clip body 1 is also provided with supporting nails for axial positioning of the workpiece.

[0010] In the working state, when the nut 3 is turned, the collet 2 moves into the cavity of the clamp body 1, and the collet 2 shrinks and clamps the workpiece under the action of the inner cone of the clamp body 1; when the nut 3 is reversed, the collet...

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 [0001] The invention relates to the technical field of clamping devices for machining shaft parts, in particular to a displacement spring collet. Background technique [0002] When machining shaft parts on the spindle of a machine tool, a special clamping device for the shaft is required to clamp and position it. At present, the clamping device used in the machining process of the shaft workpiece often has the following problems: it needs to When processing operations at different angles, because the clamping device cannot adjust the clamping angle, or the structure of adjusting the angle is more complicated, it brings inconvenience to the operation and reduces the processing efficiency. Contents of the invention [0003] The present invention aims to provide a displacement collet to solve the problem of inconvenient clamping of shaft workpieces in the prior art. [0004] In order to solve the above problems, the displacement spring collet in this solution...
