The elastic clamp has the advantage of high efficiency, is convenient to operate, and has conveniently-controlled clamping force and firm clamping.

Description

The spring chuck of holding workpiece external diameter

Technical field

The utility model relates to a kind of spring chuck that is used for the holding workpiece external diameter.

Background technology

At present, when processing axle sleeve class part, generally adopt spring chuck to come to its clamping; As the patent No. is 200720155869 disclosed a kind of spring chucks, comprise mandrel, be located at the mandrel front end collet, be loaded on the trim ring of mandrel front end by screw thread, trim ring is provided with the conical surface that matches with collet; During use,, make its clamping work pieces at the axial compression collet by the rotation trim ring; But use this anchor clamps, every replacing one subjob just need be readjusted trim ring, has operation inconvenience, lower, the unmanageable shortcoming of chucking power of efficient.

The utility model content

The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of spring chuck that is used for the holding workpiece external diameter is provided, and it has advantage easy to operate, that efficient is high, chucking power is convenient to control.

For achieving the above object, the spring chuck of holding workpiece external diameter of the present utility model, comprise hollow housing, it is characterized in that in housing, also being provided with draw ring, the core of draw ring is associated with pull bar, and the radial outer end of draw ring is associated with the spring chuck, and the front end of spring chuck is provided with the axial groove more than three or three, spring chuck front end and housing front end are provided with and match and the low conical surface in preceding high back, and the rear end of spring chuck and the endoporus of housing are slidingly matched.

During use, housing is connected with machine tool chief axis, by pulling back pull bar, the drawing clitellum spring chuck of moving endwisely slips in housing, and the conical surface pressuring spring chuck of housing front end, the front end of spring chuck be in axial shrinkage, clamping work pieces; Has advantage easy to operate, that efficient is high, chucking power is convenient to control;

As further improvement of the utility model, in the housing at draw ring rear, be connected with hollow location block set by screw thread, front end in the location block set is provided with two or more protuberances, described draw ring is provided with the axially extending bore corresponding with protuberance, the protuberance of location block set passes corresponding axially extending bore, location block set and draw ring are the gap and are provided with, and pull bar is arranged in the endoporus of location block set, also are associated with the axial location cover in the protuberance of location block set; When pulling back pull bar, the axial location cover is motionless, can carry out axial location to workpiece, holding workpiece that can be more firm;

In sum, the utlity model has advantage easy to operate, that efficient is high, chucking power is convenient to control, clamping is firm.
