Abstract
The utility model provides a drill chuck, comprising a drill body, a plurality of nuts and three jaws in threaded connection with the nuts; wherein, three inclined jaw holes are arranged in the drill body; the jaws are respectively arranged in the jaw holes; the drill chuck also comprises a rotary sleeve for driving the nuts into rotation; the rotary sleeve is made of aluminum alloy, magnesium alloy or aluminum-magnesium alloy; a rear sleeve is arranged behind the rotary sleeve, and cannot move relative to the drill body or is circumferentially fixed; the rear sleeve can be made of aluminum alloy, magnesium alloy or aluminum-magnesium alloy. The utility model has the advantages of convenient operation, reasonable deadweight of the drill chuck; less susceptibility to spoiling of the surface, easy molding and higher quality.
Description
Technical field
The utility model relates to drill chuck, relates in particular to a kind of drill chuck that is installed on machining equipment and the electric tool.
Background technology
In the prior art, no matter hand fastening drill clutch and spanner drill chuck generally comprise drill body, jaw, overcoat, nut, and three jaws are separately positioned in the jaw hole that is distributed in three inclinations on the drill body, are threaded between nut and the jaw.Therefore be provided with the connecting hole that cooperates with driving device in the rear end of drill body, drill chuck obtains power and rotates from driving device.The shell of drill chuck or make for iron or for plastics, the former not only heavily but also difficult shaping, influenced operating characteristics and outward appearance, and the latter then case hardness is damaged inadequately easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of easy operation and non-damageable new-type drill chuck.For this reason, the utility model is by the following technical solutions: it comprises drill body, nut, three jaws that are connected with nut thread, be provided with three jaw holes of inclination in the drill body, jaw is located at respectively in the jaw hole, described drill chuck also is provided with the rotary sleeve that drives the nut rotation, and described rotary sleeve is made by any one material in aluminium alloy, magnesium alloy, the almag.
For solving the problems of the technologies described above, the utility model also can be by the following technical solutions: it comprises drill body, nut, three jaws that are connected with nut thread, be provided with three jaw holes of inclination in the drill body, jaw is located at respectively in the jaw hole, described drill chuck also is provided with the rotary sleeve that drives the nut rotation, described drill chuck side after rotary sleeve also is provided with can not be with respect to drill body motion or the back cover that circumferentially is fixed, and described rotary sleeve is made by any one material in aluminium alloy, magnesium alloy, the almag.
For solving the problems of the technologies described above, the utility model also can be by the following technical solutions: it comprises drill body, nut, three jaws that are connected with nut thread, be provided with three jaw holes of inclination in the drill body, jaw is located at respectively in the jaw hole, described drill chuck also is provided with the rotary sleeve that drives the nut rotation, described drill chuck side after rotary sleeve also is provided with can not be with respect to drill body motion or the back cover that circumferentially is fixed, and described back cover is made by any one material in aluminium alloy, magnesium alloy, the almag.
Because adopt the technical solution of the utility model, the utility model is easy to operate, the deadweight of drill chuck is reasonable, and the surface is not fragile and be easy to moulding, makes drill chuck have higher quality.

The specific embodiment
With reference to attached Fig. 1 and 2.The utility model comprises drill body 1, nut 3, three jaws 4 that are connected with nut thread, be provided with three jaw holes 41 of inclination in the drill body, jaw is located at respectively in the jaw hole, described drill chuck also is provided with the rotary sleeve 2 that drives the nut rotation, and described rotary sleeve is made by any one material in aluminium alloy, magnesium alloy, the almag.Described rotary sleeve 2 can cooperate with nut by interference fit or keyway and be connected to drive the nut motion, and described rotary sleeve 2 also can drive the nut motion by the connection of other connector.The density of material of described almag with 1.6-3.5 gram/cubic centimetre for the most suitable.
In an embodiment, described drill chuck side after rotary sleeve also is provided with back cover 6, and described back cover adopts with rotary sleeve 2 same materials to be made, and back cover 6 can not or circumferentially be fixed with respect to the drill body motion.
In force, also only rotary sleeve is made by any one material in aluminium alloy, magnesium alloy, the almag or is only afterwards overlapped any one material that adopts in aluminium alloy, magnesium alloy, the almag and make, and possesses the technique effect that the utility model can reach equally.
The utility model is not only applicable to have the bivalve hand fastening drill clutch of back cover, is applicable to the monoshell hand fastening drill clutch with back cover yet.The structure that the foregoing description adopts is a hand fastening drill clutch, and the utility model is except the hand fastening drill clutch that is applicable to various structures, also applicable to spanner drill chuck.
Embodiment 2
With reference to accompanying drawing 3.Present embodiment is an example with the hand fastening drill clutch of duplex shell structure equally, and drawing reference numeral 22 and 26 is represented rotary sleeve and back cover respectively, and they all adopt any one material in aluminium alloy, magnesium alloy, the almag to make.
With reference to accompanying drawing 3.In the present embodiment, dwindled the length of back cover, the profile of present embodiment approaches the monoshell drill chuck. Drawing reference numeral 32 and 36 is represented rotary sleeve and back cover respectively, and they all adopt any one material in aluminium alloy, magnesium alloy, the almag to make.
