Description
Technical field
The utility model relates to jig device technique field, particularly a kind of collet chuck chuck.
Background technology
Collet chuck chuck is a kind of a kind of grip device that is used for fixing part to be transformed, and is arranged on the main shaft of lathe and is connected by pull bar and power source, and rotating with main shaft.Existing collet chuck chuck generally includes the push-and-pull ring that is fixed at the chuck of spindle nose, is connected and coordinates with chuck with pull bar, and described chuck is provided with the first wedge surface, and the end of push-and-pull ring is provided with the second wedge surface with the first wedge surface corresponding matching.When power source promotes the reach of push-and-pull ring by pull bar, push-and-pull ring is coordinated with the first wedge surface and is promoted chuck by the second wedge surface, and chuck is shunk, and realizes the clamping of workpiece.But the first wedge surface and the second wedge surface contact squeeze are more frequent, easily cause the first wedge surface to damage.Because existing chuck is fixed on main shaft, in the time that damaging, the first wedge surface of chuck changes difficulty, operation inconvenience, affect operating efficiency.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of simple and reasonable, easy to operate, be convenient to change chuck, collet chuck chuck that operating efficiency is higher.
For achieving the above object, the utility model is by the following technical solutions:
A kind of collet chuck chuck described in the utility model, comprise collet body, chuck, push-and-pull ring, be located at the host cavity in collet body and be fixed at the door of collet body end, described push-and-pull ring is movably arranged in described host cavity, described chuck front end is located in push-and-pull ring and its rear end and door corresponding matching, described chuck back end circumference appearance is provided with the first wedge surface, the inner wall of end of described push-and-pull ring is provided with second wedge surface corresponding with the first wedge surface, in described host cavity, be also movably equipped with push-and-pull cover, described push-and-pull cover is fixedly connected with push-and-pull ring, described collet body is provided with attachment screw.
Further, the outer wall of described push-and-pull ring is provided with gathering sill, and described collet body is provided with the guider screw coordinating with gathering sill.
Further, described push-and-pull ring outer wall is provided with the oil groove that connects its inwall, and described collet body is provided with the fuel feed hole that is communicated with described oil groove, in described fuel feed hole, is provided with sealing screw.
Further, described door is connected to described collet body by hold-down screw.
The beneficial effects of the utility model are: collet body is fixedly connected with machine tool chief axis by attachment screw, push-and-pull cover is connected to power source by pull bar, push-and-pull ring is movably arranged in described host cavity, and chuck front end is located in push-and-pull ring and rear end and door corresponding matching.When work, power source promotes the reach of push-and-pull cover by pull bar, and push-and-pull cover drives push-and-pull ring to be synchronized with the movement, and under the effect of the first wedge surface and the second wedge surface, promotes chuck and chuck is shunk.In the time that the first wedge surface of chuck damages, only need open door, it is convenient to change, and has improved operating efficiency.The utility model structure arranges advantages of simple.
