Description
Technical field
The utility model belongs to machining technique with the apparatus field, is specifically related to a kind of structure simply, the device of the convenient taking-up broken tap of energy easy and simple to handle.
Background technology
In the processing of machinery industry hole system, Drilling operation is semi-closed state, but also have blade type, coating, adjustment cutting parameter etc. to improve, and internal thread screw tap is processed, it is comparatively general mode, but can only choose, so the process of screw tap is simple and difficulty in type selecting and adjustment rotating speed.Be exactly such one " simple screw tap "; often there will be screw tap to break the phenomenon in hole when tapping; screw tap have no progeny take out very difficult; usual way is: with broken tap to have silk end to wear into spherical; this end contacts with broken tap; by the mode of beaing, make broken tap broken, then go out the screw tap fragment broken into pieces with air-blowing.But this method has following defect: because screw tap is that carbon tool steel or alloy tool steel roll tooth (or incisor) and form, hardness is high, is difficult to break into pieces, breaks into pieces not only time-consuming but also require great effort; In the process of knocking, as easy as rolling off a log manufactured thread damage; And the slag that flies knocking generation easily splashes, and causes larger potential safety hazard to operating personnel.Some screw tap breaks at the comparatively deep location in hole, be difficult to take out, can only be forced to take such as to punch on broken tap, utilize instrument to carry out reversely rotating the method for taking out broken tap, but drill process is wasted time and energy, slightly careless, also likely make drill bit break again in hole, cause quadratic loss, and the screw tap specification limit that the method can be got is less, the screw tap between M6-M14 specification can only be got, inefficiency, and the quality requirement of workpiece can not be ensured.Therefore, develop that a kind of structure is simple, the scope of application is extensive, simple to operate, can be effective fast, and be necessary without the device of the convenient taking-up broken tap of energy of safety hazard.
Utility model content
The utility model is to provide that a kind of structure is simple, the scope of application is extensive, simple to operate, and the device of the convenient taking-up broken tap of energy without safety hazard.
The utility model is achieved in that and comprises square toes, shank, claw, draw-in groove and groove of cooling down, and described shank left end arranges square toes, right-hand member arranges claw, described claw comprises three-jaw or/and four paws, arranges draw-in groove between every two pawls, arranges groove of cooling down inside described claw and the root of draw-in groove.
Broken tap clamps and carries out having reversely rotated the mode that screw tap screws out screwed hole by the utility model employing claw and draw-in groove, broken tap blade is blocked by draw-in groove, claw enters in broken tap groove and carries out multi-surface contact, by multiplex strand hand, square toes are exerted a force, carry out rightabout rotary motion when screwing in broken tap, draw-in groove automatic clamping blade, claw is automatically firmly grasped screw tap groove and is rotated, broken tap carries out reverse rotation and screws out screwed hole, chip breaking screws out outside hole together with screw tap can not produce splashing, and manufactured threaded portion can not be damaged.This utility model does not need to apply great power to square toes when getting broken tap, very fast just can take out broken tap, and the design of square toes also can clamp with spanner, pliers instrument except with except the clamping of hinge hand, uses flexibly and easily.The broken tap scope that the utility model can be got is M6-M30, more extensive than the market similar tools scope of application.

Fig. 2 is the right TV structure schematic diagram (four paws figure) of Fig. 1;
Fig. 3 is the right TV structure schematic diagram (three-jaw figure) of Fig. 1;
In figure: 1-square toes, 2-shank, 3-claw, 4-draw-in groove, 5-cools down groove.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, but limited the utility model never in any form, any conversion done based on the utility model training centre or improvement, all fall into protection domain of the present utility model.
As shown in Figures 1 to 3, the utility model comprises square toes 1, shank 2, claw 3, draw-in groove 4 and groove 5 of cooling down, described shank 2 left end arranges square toes 1, right-hand member arranges claw 3, described claw 3 comprises three-jaw or/and four paws, between every two pawls, draw-in groove 4 is set, inside described claw 3 and the root of draw-in groove 4, groove 5 of cooling down is set.After broken tap clamps by claw 3 and draw-in groove 4, with multiplex hinge hand, square toes 1 are exerted a force, reversely rotated broken tap and screwed out screwed hole.
The integral structure that described square toes 1, shank 2 and claw 3 are formed for spring steel material.
Described square toes 1 are that four directions is or/and six sides.These square toes 1 when getting broken tap for clamp.Square toes 1 are for applying power position during work, and its square toes are of a size of between 6mm-20mm.Square toes 1 carry out sticking into force for multiplex hinge hand.
The described diameter of shank 2 and the thread size of broken tap adapt.Shank 2 in order to calibrate thread size, the thread size 0.10mm-0.15mm larger than the excircle dimension of shank 2 of broken tap.
The depth dimensions that the length dimension of the described shank 2 described in shank 2 and broken tap break in hole adapts.As screw tap breaks in deep hole, then the shank 2 getting the device of broken tap should be grown; As broken in shallow bore hole, then shank 2 should be short.
Cat's paw's width dimensions of described claw 3 and the groove width size of broken tap adapt.Claw 3, according to the difference of got broken tap, is divided into three-jaw and four paws, gets M6-M12 broken tap three-jaw; Get and be greater than four paws when M12 is less than or equal to the broken tap of M30.
The ratio of the groove width size of described draw-in groove 4 and the screw claw width dimensions of broken tap is 1.1:1 ~ 1.2:1.
The ratio of the groove depth size of described draw-in groove 4 and the screw claw length dimension of broken tap is 1.1:1 ~ 1.3:1.
Described draw-in groove 4 arranges circular arc with claw 3 connecting part, and the two arc transition connects.
Described groove 5 of cooling down is for circular arc bottom structure, and arc edge is connected with the root rounding off of draw-in groove 4 with claw 3.
operation principle of the present utility model and process:
The utility model adopts draw-in groove 4 to be blocked by broken tap blade, claw 3 enters in broken tap groove and carries out multi-surface contact, by multiplex strand hand, square toes 1 are exerted a force, carry out rightabout rotary motion when screwing in broken tap, draw-in groove 4 automatic clamping blade, claw 3 is automatically firmly grasped screw tap groove and is rotated, and broken tap carries out reverse rotation and screws out screwed hole, chip breaking screws out outside hole together with screw tap can not produce splashing, and manufactured screw thread lines can not be damaged.This device does not need to apply great power to square toes 1 when getting broken tap, very fast just can take out broken tap, and the design of square toes 1 also can clamp with spanner, pliers instrument except with except the clamping of hinge hand, uses flexibly and easily.
This utility model has that structure is simple, the scope of application is extensive, simple to operate, can be effective fast, and without the feature of safety hazard, convenient taking-up broken tap.
