Abstract
A chuck protector includes the chuck and the protector, the protector includes a shaft sleeve which connects to a screw, a protecting sleeve or a protecting set is arranged at the front end of the screw, trisected or quartered plane and groove are arranged on the external cylinder of the protecting sleeve or the protecting set, a folded extension block is fixed to the plane and the groove, the folded extension block is arranged in the chucking jaw groove of the chuck, one end of the folded extension block contacts the chuck jaw, the folded extension block motions up and down in the chucking jaw groove accompanying with the motion of the chuck jaw in the chuck, so that plane screw thread is not exposed outward and becomes iron scrap-proof.
Description
Technical field
The utility model relates to chuck, mainly is meant a kind of chuck protector.
Background technology
The existing machine tool chuck mainly is made up of chuck body, claw, bevel gear, flat thread.Claw clamping work pieces at chuck carries out in the process, and iron filings fall in the flat thread of chuck easily, and claw and flat thread are ground, thereby influence the chuck precision, reduce chuck service life, reduce the workpiece crudy, waste man-hour and increase labour intensity.
Summary of the invention
The purpose of this utility model provides a kind of chuck protector, by protective sleeve or protective disc and folding retractable block structure are set, prevent that iron filings from entering in the flat thread of chuck, thereby has solved the problem that existing chuck easily advances iron filings.
The realization the technical solution of the utility model is: this protector comprises chuck and protector; its primary structure is that described protector comprises an axle sleeve; this axle sleeve connects a screw rod; this screw front end is provided with protective sleeve; the cylindrical of this protective disc is provided with groove; be provided with the folding retractable piece in this groove, this flexible piece is arranged in the claw groove of chuck, and the one end contacts with claw.
This technical scheme also comprises:
Described screw front end is provided with protective sleeve, and this cover cylindrical is provided with guard ring, and this guard ring is provided with the folding retractable piece.
The claw quantity of the corresponding chuck of the quantity of described folding retractable piece.
Described axle sleeve is a tapered sleeve.
Described protective disc is provided with the flute profile piece, is provided with the folding retractable piece in this flute profile piece.
The beneficial effect that the utlity model has: 1, can prevent effectively that iron filings from entering in the flat thread of chuck; 2, simple in structure, easy accessibility; 3, prolong chuck service life; 4, have scroll chuck and chuck versatility.
