Description
Technical field
The utility model is related to take silk device technical field, specially a kind of combined type withdrawing device for broken threaded parts.
Background technology
In mechanical processing process, workpiece usually needs punching to drill, and broken tap then occurs when being punched using screw tap often
Phenomenon, therefore and the case where causing workpiece to scrap it is very much, once had the method for report high temperature melting that broken tap fusing is reached work
Part recycles purpose, but this high temperature melting generating means structure is more heavy, and height is unable to reach industrial applications and wants another cost again
It asks, therefore silk fetching equipment occurs, the prior art is first to be punched on fracture of wire, and silk is being taken with silk fetching equipment, and step is more, for this purpose, we
Propose a kind of combined type withdrawing device for broken threaded parts.
Utility model content
The purpose of this utility model is to provide a kind of combined type withdrawing device for broken threaded parts, to solve to propose in above-mentioned background technology
The prior art be first punched on fracture of wire, taking silk, the more problem of step with silk fetching equipment.
The utility model is implemented by following technical solution：A kind of combined type withdrawing device for broken threaded parts, including electric drill body, the electric drill
The output shaft left end of body is connected with connection pullover, and the left end of the connection pullover is plugged with connector, the left end of the connector
It is connected with silk fetching equipment, the left end of the silk fetching equipment is connected with derotation drill bit, and the left end of the silk fetching equipment is provided with embedded head, and embedding
Enter head to be plugged into the right side wall of derotation drill bit, the derotation drill bit is connect by embedded type bolt with embedded head.
Preferably, the radial section of the connector is rectangle, and the inner wall of the connection pullover is adapted with connector.
Preferably, be plugged with trip bolt at the top of the connection pullover, the right end of the connector outer wall offer with
The compatible screw hole of trip bolt.
Preferably, the length of the derotation drill bit is 0.5cm-1cm.
(1) compared with prior art, the utility model has the beneficial effects that：The combined type withdrawing device for broken threaded parts reduces operation
Step, it is easy to operate, drill it is synchronous with silk is taken carry out, when work, reduces operating personnel, using derotation drill bit, can make fracture of wire more
It is easy to take out.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other drawings may also be obtained based on these drawings.
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the fractionation structural representation of the utility model silk fetching equipment and derotation drill bit.
In figure：1 electric drill body, 2 connection pullovers, 3 connectors, 4 silk fetching equipments, 5 derotation drill bits, 6 insertion heads.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of combined type withdrawing device for broken threaded parts, including electric drill
The output shaft left end of body 1, the electric drill body 1 is connected with connection pullover 2, and the left end of the connection pullover 2 is plugged with connector 3,
The left end of the connector 3 is connected with silk fetching equipment 4, and the left end of the silk fetching equipment 4 is connected with derotation drill bit 5, the left end of silk fetching equipment 4
Be provided with embedded head 6, and embedded head 6 is plugged into the right side wall of derotation drill bit 5, derotation drill bit 5 by embedded type bolt with it is embedding
Enter first 6 connection.
Wherein, the radial section of the connector 3 is rectangle, and the inner wall of the connection pullover 2 is adapted with connector 3,
The top of the connection pullover 2 is plugged with trip bolt, and the right end of 3 outer wall of the connector is offered to be adapted with trip bolt
Screw hole, the length of the derotation drill bit 5 is 0.5cm-1cm.
Operation principle：Corresponding drill bit is chosen according to the size of fracture of wire, connector 3 is connected with pullover 2 is connect, electric drill
Body 1 drives derotation drill bit 5 to rotate, and derotation drill bit 5 will not bring clast up, and clast is avoided to be ground to the inner wall of trepanning and to taking
The damage of silk device 4, after fracture of wire is reached the position of silk fetching equipment 4 by derotation drill bit 5, the hand of spiral and fracture of wire of 4 outer wall of silk fetching equipment
The hand of spiral on the contrary, the outer diameter of silk fetching equipment 4 is from left to right sequentially increased, with entering in drilling for silk fetching equipment 4, silk fetching equipment 4
It is increasing with the squeezing action power of drill hole inner wall, until silk fetching equipment 4 is kept opposite by larger frictional force self-locking with fracture of wire
Static, silk fetching equipment 4 is rotated further under the action of electric drill body 1, to which silk fetching equipment 4 screws out fracture of wire, derotation drill bit 5 and silk fetching equipment
4 be used as connecting pin by embedded head 6, in use can according to carried out the case where effective object replacement derotation drill bit 5 or
After derotation drill bit 5 is useless, the normal use of silk fetching equipment 4 reduces cost.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
