Abstract
The utility model provides a novel self-locking hand-tightening drill chuck, which comprises a drill body, a chuck jaw, a screw nut forming a screw-thread connection with the chuck jaw, and a rotary sleeve axially limited for operating the screw nut. The utility model is also provided with an elastic locking element and an installation element of the elastic locking element connected with the screw nut. The drill body is provided with a saw tooth ring matching with the locking element, and the inner wall of the rotary sleeve is provided with a configuration for controlling the matching state of the locking element and the saw tooth ring. The utility model solves the self-locking problem of the drill chuck by locking and matching the screw nut with the drill body. Therefore, the structure is more simple. The utility model not only can be applied to a single-set drill chuck, but also can be applied to a double-set drill chuck. Meanwhile, the elastic locking element is arranged on the screw nut by adopting the installation element, which can simplify the processing of the elements and is convenient for assembly. Meanwhile, the locking force is stronger.
Description
Technical field
The utility model relates to a kind of drill chuck, relates in particular to a kind of for example drill chuck on the drilling machine of machining equipment and electric tool that is installed in.
Background technology
In the prior art, be provided with the rotary sleeve of drill body, jaw, nut, operating nut in the hand fastening drill clutch, three jaws are separately positioned in three inclined holes that are distributed on the drill body, adopt between nut and the jaw and be threaded, interference fit or employing key connecting drive jaw and clamp or the drilling tool that gets loose with operating nut between rotary sleeve and the nut.The shortcoming of this drill chuck is: under the load that the is hit effect, the drill bit of jaw clamping is easily loosening to skid even comes off, and is difficult to keep the continuity of processing.
For this reason, the hand fastening drill clutch of band auto-lock function is arranged at present, overcoming above-mentioned defective, but the structure more complicated is not strong from latching operation and clamp operation continuity, the convenience that influence is operated.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel self-locking hand fastening drill clutch simple in structure.For this reason, the utility model is by the following technical solutions: it comprises drill body, jaw, the nut that is threaded with jaw, the axial rotary sleeve of limited operating nut, it also is provided with the installed part that the elastic locking element reaches the elastic locking element that is connected with nut, drill body is provided with the sawtooth circle that cooperates with locking member, and the rotary sleeve inwall is provided with the configuration of control locking member and sawtooth circle mated condition.Owing to adopt above technical scheme, the utility model solves the self-locking problem of drill chuck by making nut and drill body lock fit, structure is more simple, can be applied to single cover drill chuck and also can be applied to two cover drill chucks, the elastic locking element adopts installed part to be installed on the nut simultaneously, assembling is convenient in the processing that can simplify part, and it is stronger to lock strength simultaneously.
The method that the elastic locking element is installed on the nut is a lot, further, the utility model provides a kind of more simple, more reliable elastic locking element mount scheme of installation: described installed part is the round element that is enclosed within nut cylindrical and interference fit, the elastic locking element is provided with the installation position, and the nut cylindrical is provided with the elastic locking element mounting groove that cooperates with described installation position.
The elastic locking element comprises one section spring leaf to play locking function, and spring leaf is provided with outside projection, and described rotary sleeve inwall control locking member is the groove that cooperates with projection with the structure of sawtooth circle mated condition.Like this, the self-locking operational motion is identical with the clamp operation direction of action, becomes the continuity of clamp operation action, more meets use habit, and it is more convenient to operate, and is very good in sense.
The rotary sleeve inwall is provided with the transposition groove, and nut is provided with the transposition key that is in the transposition groove.Like this, be convenient to locking and clamp operation, be beneficial to the clamping force when improving the drill chuck clamping.
Described rotary sleeve inwall is provided with the boss that cooperates with installed part.Like this, make installed part also can play effect, make the result compact more simple the rotary sleeve axial limiting.
