Abstract
The utility model discloses a drill chuck with locking sound, which is composed of three chucking jaws arranged in a chucking jaw hole of a drill body, a screw nut sheathed on the rear parts of the chucking jaws, and a sleeve barrel sheathed out of the screw nut, wherein the screw nut forms a screw-thread fit with the chucking jaws, and the sleeve barrel can drive the screw nut to rotate. A bearing is arranged between the sleeve barrel and the screw nut. When the chucking jaws are locked, the bearing can generates sound to prompt an operator. Therefore, the utility model can avoid the defect of judging whether the chucking jaws are chucked by hand feeling or experience.
Description
Technical field
The utility model relates to a kind of drill chuck with locking sound.
Background technology
In the prior art, drill chuck generally comprises three jaws in the jaw hole that is installed in drill body, be enclosed within the jaw rear portion and with the nut of jaw threaded engagement, to be enclosed within nut outer and drive the sleeve that nut rotates.During work, user's rotational sleeve drives nut, and nut can make jaw flexible, clamps when jaw stretches out, and unclamps during the jaw indentation, and its shortcoming is that the clamping degree of jaw can only rely on feel and experience thereof to judge.
Summary of the invention
The purpose of this utility model is: a kind of drill chuck with locking sound is provided, it adds bearing between sleeve and nut, during jaw locking, bearing can sound the prompting operation worker, can avoid relying on feel or experience to judge the defective whether jaw clamps.
The technical solution of the utility model is: a kind of drill chuck with locking sound, comprise and be installed in sleeve, drill body, jaw and nut, be provided with bearing between described sleeve and the nut, bearing comprises lasso, the rear portion and the drill body of lasso are fixed, the front inner wall of lasso is provided with a circle double wedge, the inner ring of double wedge is provided with several pieces arc spring leafs, arc spring leaf extends forward and inserts in the groove that nut outer wall is provided with, the both sides of arc spring leaf are respectively equipped with lateral plate, the termination of two lateral plates is respectively equipped with A projection and the B projection that outwards protrudes out, wherein also be provided with the moving tooth that outside double wedge, sticks up on the lateral plate of B rear raised portion, sleeve lining is on the circumference corresponding to A projection and B raised position, be provided with two pocket corresponding to an A projection, be provided with a little depression and a big depression corresponding to a B projection, when jaw was relaxed state, the A projection embedded in the pocket, and the B projection embeds in the little depression.
The further technical scheme of the utility model is: a kind of drill chuck with locking sound, comprise and be installed in sleeve, drill body, jaw and nut, be provided with bearing between described sleeve and the nut, bearing comprises lasso, the rear portion and the drill body of lasso are fixed, the front inner wall of lasso is provided with a circle double wedge, the inner ring of double wedge is provided with three arc spring leafs, the inwall of lasso is provided with step at the rear portion of double wedge, the rear end face of arc spring leaf is conflicted on step, arc spring leaf extends forward and inserts in the groove that nut outer wall is provided with, the both sides of arc spring leaf are respectively equipped with lateral plate, the termination of two lateral plates is respectively equipped with A projection and the B projection that outwards protrudes out, and wherein also is provided with the moving tooth that sticks up on the lateral plate of B rear raised portion outside double wedge, and sleeve lining is on the circumference corresponding to A projection and B raised position, be provided with two pocket corresponding to an A projection, be provided with a little depression and a big depression corresponding to a B projection, when jaw was relaxed state, the A projection embedded in the pocket, and the B projection embeds in the little depression.
During rotational sleeve, because the A projection of the lateral plate termination of arc spring leaf is arranged in pocket, the B projection is arranged in little depression, and the internal diameter of little depression is less, so little depression inwardly pushes away B projection and moving tooth, moving tooth leaves the double wedge of bearing, making sleeve can drive arc spring leaf rotates, arc spring leaf drives nut again, and nut drives jaw, jaw is clamped or unclamps.
When jaw clamps, nut just can not rotate, if again during rotational sleeve, sleeve can only drive arc spring leaf and rotate, the A projection of the lateral plate termination of arc spring leaf is moved in another pocket by a pocket, send " clatter " one, simultaneously, the B projection moves to the big depression from little depression, because the internal diameter of big depression is bigger, make moving tooth contact double wedge, send continuous " clatter, clatter " sound, show that jaw locks.
The utility model has the advantages that:
The utility model adds bearing between sleeve and nut, during jaw locking, bearing can sound the prompting operation worker, can avoid relying on feel or experience to judge the defective whether jaw clamps.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the assembling schematic diagram of sleeve, bearing, nut.
Wherein: 1 sleeve; 2 drill bodies; 3 jaws; 4 nuts; 5 bearings; 6 lassos; 7 double wedges; 8 arc spring leafs; 9 grooves; 10 lateral plates; The 11A projection; The 12B projection; 13 moving teeth; 14 pocket; 15 little depressions; 16 big depressions; 17 steps.
The specific embodiment
Embodiment: as Fig. 1, shown in Figure 2, a kind of drill chuck with locking sound, be installed in three jaws 3 in the jaw hole of drill body 2, be enclosed within jaw 3 rear portions and with the nut 4 of jaw 3 threaded engagement, it is outer and drive the sleeve 1 that nut 4 rotates to be enclosed within nut 4, be provided with bearing 5 between described sleeve 1 and the nut 4, bearing 5 comprises lasso 6, the rear portion of lasso 6 and drill body 2 are fixing, the front inner wall of lasso 6 is provided with a circle double wedge 7, be provided with step 17 between the front portion of lasso 6 and the rear portion, the inner ring of double wedge 7 is evenly equipped with three arc spring leafs 8, the rear end face of three arc spring leafs 8 is conflicted on step 17, arc spring leaf 8 extends forward and inserts in the groove 9 that nut 4 outer walls are provided with, the both sides of arc spring leaf 8 are respectively equipped with lateral plate 10, the termination of two lateral plates 10 is respectively equipped with A projection 11 and the B projection 12 that outwards protrudes out, wherein also be provided with the moving tooth 13 that outside double wedge 7, sticks up on the lateral plate 10 at B projection 12 rear portions, sleeve 1 inwall is on the circumference corresponding to A projection 11 and B projection 12 positions, be provided with two pocket 14 corresponding to an A projection 11, be provided with a little depression 15 and a big depression 16 corresponding to a B projection 12, A projection 11 embeds in the pocket 14, and B projection 12 embeds in the little depression 15.
During rotational sleeve 1, because the A projection 11 of lateral plate 10 terminations of arc spring leaf 8 is arranged in pocket 14, B projection 12 is arranged in little depression 15, and the internal diameter of little depression 15 is less, so little depression 15 inwardly pushes away B projection 12 and moving tooth 13, makes moving tooth 13 leave the double wedge 7 of bearing 5, sleeve 1 can drive arc spring leaf 8 and rotate, arc spring leaf 8 drives nut 4 again, and nut 4 drives jaws 3, jaw 3 is clamped or unclamps.
When jaw 3 clamps, nut 4 just can not rotate, if again during rotational sleeve 1, sleeve 1 can only drive arc spring leaf 8 and rotate, the A projection 11 of lateral plate 10 terminations of arc spring leaf 8 is moved in another pocket 14 by a pocket 14, send " clatter " one, simultaneously, B projection 12 moves to the big depression 16 from little depression 15, because the internal diameter of big depression 16 is bigger, make moving tooth 13 contact double wedge 7, send continuous " clatter, clatter " sound, show that jaw 3 locked.
