Abstract

The utility model relates to a drill chuck with a baffle and a key, and belongs to the technical field of machinery. The drill chuck disclosed by the utility model is characterized by comprising a drill chuck positioning hole, a chuck body, a chuck sleeve, a clamping jaw driver, a key baffle, an internal threaded ring, a clamping jaw and a key positioning hole, wherein the key baffle is sleeved on the outside of the chuck sleeve, and the front part of the key baffle is in the shape of a slope and identical with a slope of a chuck key. The key comprises a positioning pin, an external threaded ring, a force-applied rod, a key body, a sliding spring and a sliding hole, wherein the key body is provided with the sliding hole, the sliding spring is arranged in the sliding hole, the sliding spring is connected with the positioning pin, and the sliding spring drives the positioning pin to move forward and backward. The drill chuck and key disclosed by the utility model have the beneficial effects that the drill chuck and the key are simple in structure and easy to use; and when in use, a chuck handle does not fall off, so that the drill chuck and key disclosed by the utility model can be widely applied to related mechanical devices such as machine tools and drilling machines and the like, therefore, the drill chuck and key disclosed by the utility model have a good market prospect.

Description

A kind of drill chuck and key with baffle plate

Technical field

The utility model belongs to field of mechanical technique, relates to a kind of lathe and drilling machine drill chuck commonly used.

Background technology

Whether existing drill chuck generally pays attention to the stick of tool head, inconsiderate to the key of drill chuck, if the phenomenon that key comes off from drill chuck appears in undue force or the big city of exerting oneself during use.

Summary of the invention

The utility model provides a kind of drill chuck and key with baffle plate.

The technical scheme of the utility model is following:

A kind of drill chuck with baffle plate comprises drill chuck locating hole, collet body, chuck cover, jaw driver, key baffle plate, internal thread circle, jaw, key positioner hole; The key baffle-plate-sleeve is outside at the chuck cover, and the slope that its front portion is ramped shaped and chuck handle matches; Comprise external screw thread circle, alignment pin, boosting-rod, key body, sliding spring, sliding eye with a kind of key that matches with the drill chuck of baffle plate, sliding spring can slide in key body, promotes alignment pin and moves forward and backward; During use, earlier the external screw thread circle of chuck handle and the internal thread circle of drill chuck are combined closely, after the slope of the slope of chuck handle and drill chuck baffle plate matches, alignment pin is inserted the key positioner hole, just can use through sliding spring.

The beneficial effect of the utility model is simple in structure, and is easy to use, and chuck handle does not come off during use, can be widely used in associated machines such as lathe and drilling machine, and good market prospects are arranged.
