Description
Technical field
The utility model is related to a kind of Self-locking drill-chuck.
Background technology
In the prior art, drill body, clamping jaw, nut are provided with drill chuck, drive clamping jaw to transport forward by rotating nut
Move or move backward and make drill point head clamping or release drilling tool.Self-locking structure is to prevent drill chuck at work in drill chuck
When the reaction force acts that are subject to by it and cause the structure that drilling tool released, it is carried out by spring leaf and the tooth being on drill body
Coordinate, spring leaf is then in nut sleeve.Current Self-locking drill-chuck, spring leaf not merely undertakes auto-lock function, drill chuck
Nut in the wholly or largely stroke that clamping direction is rotated, rotary sleeve is required for being driven by spring leaf, but bullet
The need for the material of reed first has to meet own as self-locking structure part after all, so, spring leaf is determined rotary sleeve
Position confining force is smaller, not strong in the handover operation feel for entering self-locking state and exit from self-locking state, is not easy to operation.
Have and directly make in nut sleeve spring leaf, but the material of nut sleeve is too hard, can more influence the self-locking operating characteristics of drill chuck.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of Self-locking drill-chuck, to improve self-locking clamping chuck of drill bit behaviour
Make feel and keep self-locking property.Therefore, the utility model uses following technical scheme：
A kind of Self-locking drill-chuck, including nut sleeve, the self-locking that rotary sleeve, drill body, nut, clamping jaw, metal sheet are made
Structure, nut and nut are connected, and the self-locking structure includes tooth and spring leaf, and the tooth is on drill body or is in and is fixed on brill
On part on body, the spring leaf has the lock end being engaged with tooth, it is characterised in that：
The front end of the nut sleeve has and the attachment structure that nut sleeve is continuous one；The nut is led to by rotary sleeve
The attachment structure for crossing the continuous one directly drives rotation, and the rotary sleeve circumferencial direction by the continuous one company
Resilient spots localization on binding structure.
On the basis of using above-mentioned technical proposal, the utility model can also be using technical scheme or right further below
These further solution pools are used：
It is described to be under self-locking state in drill chuck, by the gear in the attachment structure on the key on rotary sleeve and nut sleeve
Side coordinates drive nut driving the side of clamping jaw extension to be rotated up；
Also there is elastic cantilever in the attachment structure of the continuous one, there is projection on elastic cantilever；The rotation
Peripherally disposed the first groove and the second groove having with the male cooperation on pivoted housing；By the first groove and the projection
Cooperation and drill chuck be in self-locking state under to rotary sleeve position；With the second groove and the projection and in drill point
Head is positioned under unlocked state to rotary sleeve, and when rotary sleeve is rotated by the second groove and the raised cooperation
Drive nut sleeve and nut rotation.
The front end of the nut sleeve has the groove coordinated with rotary sleeve, and the side of groove is the rib；The flexure strip
It is connected in nut sleeve, and the rear in the attachment structure in the axial direction.
The spring leaf has groove type warp architecture raised laterally, by groove type warp architecture and nut sleeve
Hole clamping, on the rotary sleeve have to the groove type warp architecture have step down and position-limiting action groove.
The cooperation of the spring leaf and tooth by cam surface and the spring leaf of rotary sleeve inwall near the convex laterally of lock end
The cooperation control for rising.
Due to using the technical solution of the utility model, the utility model had both improved self-locking drill point by simple mode
Head operating handle simultaneously keeps self-locking property.

Specific embodiment
Referring to the drawings.Self-locking drill-chuck provided by the utility model, including rotary sleeve 2, drill body 1, nut 3, clamping jaw
4th, the nut sleeve 7, self-locking structure being made up of metal sheet, the self-locking structure includes tooth 11 and spring leaf 8, and the tooth 11 is in
On drill body 1 or it is on the part being fixed on drill body 1, the spring leaf 8 has the lock end 80 being engaged with tooth 11.
Nut 3 is connected as one by two halfbodies by the nut sleeve 7.The front end of the nut sleeve 7 has and nut
Set 7 is the attachment structure of continuous one, and so, attachment structure and nut sleeve 7 are same material and make together.
It is direct by the attachment structure of the continuous one by rotary sleeve 2 that spring leaf 8 is responsible for self-locking, the nut 3 specially
Drive and rotate, and the rotary sleeve 2 resilient spots localization, spiral shell in attachment structure of the circumferencial direction by the continuous one
The attachment structure of the described continuous one of mother set is participated in self-locking, but only increases it to rotary sleeve 2 in self-locking and unlocked two
Positioning under individual state and the torsion transmission work under unlocked state, during the switching of two states of not locking in self-locking and,
It is obtained in that stronger handover operation is felt and clearly pointed out in place, and increases under described two states to rotary sleeve
Circumferentially positioned power.
It is described to be under self-locking state in drill chuck, by the attachment structure on the key 24 on rotary sleeve 2 and nut sleeve
Rib 74 coordinate drive nut drive clamping jaw extension side be rotated up.
Also there is elastic cantilever 73 in the attachment structure of the continuous one, have raised 71 on elastic cantilever；Institute
State peripherally disposed the first groove 21 and the second groove 22 having with the male cooperation on rotary sleeve 2；By the first groove
21 and raised 71 cooperation and drill chuck be in self-locking state under rotary sleeve 2 is positioned；By the second groove 22 and described
Raised 71 cooperation and rotary sleeve 2 is positioned in the case where drill chuck is in unlocked state, and pass through second when rotary sleeve 2 is rotated
Groove 22 and raised 71 cooperation and drive nut sleeve and nut rotation.
The front end of the nut sleeve 3 has the groove 72 coordinated with rotary sleeve, and the side of groove 72 is the rib 71；The bullet
Property piece 8 be also connected in nut sleeve 3, and in the axial direction in the attachment structure rear.
The spring leaf 8 has groove type warp architecture 81 raised laterally, by groove type warp architecture 80 and spiral shell
The clamping of hole 75 in mother set, has to have the groove type warp architecture 81 on the rotary sleeve 2 and steps down and position-limiting action
Groove 25.
The cooperation of the spring leaf 8 and tooth 11 by cam surface 26 and the spring leaf of rotary sleeve inwall near the outside of lock end
The cooperation control of side projection 82.
