Abstract
The utility model relates to a novel drill chuck which increases locking tightness by means of increasing moment, comprising a chuck body, a jaw, a locking nut, a circular coat of the drill chuck, wherein, the main technique point is that the side wall of the circular coat of the rill chuck is provided with at least one locking and positioning hole. The utility model is added with the locking and positioning hole arranged on the coat of the drill chuck , so that a drill bit or a screw tap can be locked tightly or detached through rotating a spanner or the spanner directly rotating the coat of the drill chuck without the gear structure processed at the edge of the coat of the drill chuck, thereby lowering the cost; in addition, the utility model also has the advantages of simple and reasonable structure, low manufacturing cost, convenient assembly and maintenance, wide range of use, and long service life, etc.
Description
Technical field
The utility model relates to the Machining Technology field, specifically a kind ofly is used for the novel drill chuck that clamping drill bit or screw tap carry out machining by metal cutting and industrial electric drill.
Background technology
As everyone knows, by drilling machine, lathe or wash bed and carry out metal cutting and industrial electro is crept into capable clamping drill bit or screw tap carries out in the cutting process, all need drill bit or screw tap is fastening by drill chuck.At present, traditional drill chuck mainly comprises: two kinds of structures of spanner drill chuck and self-locking clamping chuck of drill bit, preceding a kind of structure in use, be three pawls that elder generation puts into drill bit or screw tap drill chuck, then by being with the special spanner of bevel gear, its front end is inserted in the spacing hole on the drill body sidewall, the tooth of bevel gear also just in time is meshed with tooth on the drill chuck overcoat edge, rotate special spanner then, drill chuck overcoat and drill body are relatively rotated, at this moment, the locking nut that rotates simultaneously with the drill chuck overcoat will drive three claws in the drill chuck and shrink in drill body and move and clamp drill bit or screw tap spacing.Because the locking torque of special spanner is not enough, in addition, the influence for the material factors of drill chuck self material and processed parts is restricted its locking degree; There is the not enough defective of locking torque equally in then a kind of structure.People often hit by the long sleeve pipe of increase on special spanner or with hammer in order to increase the locking degree, but greatly reduce the service life of drill chuck.
Summary of the invention
The purpose of this utility model provides a kind of novel drill chuck that increases the locking degree by the mode that increases moment.
The purpose of this utility model is achieved in that it includes clamp, claw, and locking nut, the drill chuck round jacket is characterized in that: be provided with a locking spacing hole on the sidewall of drill chuck round jacket at least.
For the ease of rotating the drill chuck round jacket, then the sidewall of drill chuck round jacket is provided with three or four locking spacing holes and is advisable.
The purpose of this utility model realizes equally in the following way: it includes clamp, claw, locking nut, the drill chuck round jacket is characterized in that: in have corresponding parallel two planar structures of outer wall for ease of rotating of drill chuck round jacket, perhaps be quadrangle, pentagon, hexagon, heptagon, eight-sided formation.
The utility model is set up the locking spacing hole owing to putting outside drill chuck, or its outer wall is processed into corresponding two planar structures of being convenient to rotate that have, and perhaps is quadrangle, pentagon, hexagonal structure; Make it pass through rotating spanner or spanner directly rotates the drill chuck overcoat, with drill bit or screw tap locking or dismounting.And need not to have reduced cost at drill chuck overcoat edge processing gear structure, it is simple and reasonable that the utility model also has, low cost of manufacture, and installation and maintenance is very convenient, and range of application is wide, advantages such as long service life.
Description of drawings
Fig. 1 is a stereochemical structure simplified schematic diagram of the present utility model;
Fig. 2 is that claw in the utility model is by precession state diagrammatic sectional view;
Fig. 3 is that the claw in the utility model is screwed out the state diagrammatic sectional view;
Fig. 4 is the utility model rotates the drill chuck overcoat by spanner a user mode simplified schematic diagram;
To be described in further detail the utility model by example below; but following example only is the utility model example wherein; the rights protection scope of not representing the utility model and being limited, rights protection scope of the present utility model is as the criterion with claims.
The specific embodiment
Embodiment 1:
Shown in Fig. 1～4,1 among the figure is clamp, and 2 is claw, and 3 is the drill chuck round jacket, and 5 is locking nut, evenly is provided with four locking bar shaped spacing holes 4 that are used for spacing rotating spanner 6 on the sidewall of drill chuck round jacket 3.This structure in use, be three pawls that elder generation puts into drill bit or screw tap drill chuck, then by spanner 6, its front end is inserted in the bar shaped spacing hole 4 on the drill chuck sleeve side wall (shown in Figure 4), rotating spanner 6 then, drill chuck overcoat 3 and drill body 1 are relatively rotated, at this moment, the locking nut 5 that rotates simultaneously with the drill chuck overcoat will drive three claws 2 in the drill chuck in drill body, shrink move or to drill body outside, open mobile, and clamp drill bit or screw tap spacing or open moving and den bohrkopf abbauen (Fig. 2 and state shown in Figure 3), and realize the purpose of this utility model.
The utility model also can be as required, will be in have corresponding parallel two planar structures of outer wall for ease of rotating of drill chuck round jacket, it perhaps is quadrangle, pentagon, hexagon, heptagon, eight-sided formation, specially rotate the drill chuck round jacket by rotating spanner again, can realize the utility model purpose equally.
