Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, the utility model discloses one kind to take screw hole Broken bolt tooling, including what is be detachably connected
Electric drill and drill bit, drill bit include grooved bit 1 and withdrawing device for broken threaded parts 2, wherein grooved bit 1 breaks for drilling on Broken bolt
Silk extractor 2 is used to be inserted into the drilling of Broken bolt and takes out Broken bolt.
It should be noted that the bottom end of grooved bit 1 and withdrawing device for broken threaded parts 2 can be with electric drill (specially drill bit
Jack) it connects, the top (i.e. working end) of grooved bit 1 and withdrawing device for broken threaded parts 2 is respectively used to drill and be inserted on Broken bolt
The drilling of Broken bolt.
Screw hole Broken bolt tooling is taken in the application, grooved bit 1 is connected on electric drill first, with electric drill in Broken bolt
Then upper drilling removes grooved bit 1, withdrawing device for broken threaded parts 2 is connected on electric drill, withdrawing device for broken threaded parts 2 is inserted into grooved bit 1
In the drilling previously accomplished fluently on Broken bolt, electric drill is opened, opposite Broken bolt screw thread lines reversely rotates withdrawing device for broken threaded parts 2, will
Broken bolt takes out.Using above-mentioned tooling, working efficiency can be effectively improved, and can guarantee and successfully take out Broken bolt.
In further embodiment, grooved bit 1 and withdrawing device for broken threaded parts 2 include three parts, that is, for connecing with Broken bolt
Working end, interlude and the bottom end for connecting electric drill of touching.Wherein, the interlude of the two can be cylindrical body or polygon column
Body.
Particularly, in order to enhance withdrawing device for broken threaded parts 2 and Broken bolt drilling connection tightness, 2 working end of withdrawing device for broken threaded parts
Outer diameter be greater than 1 working end of grooved bit outer diameter.2 working end outer diameter of withdrawing device for broken threaded parts is slightly larger than 1 working end of grooved bit
Outer diameter, 2 working end of withdrawing device for broken threaded parts are inserted into the drilling of Broken bolt, and interference fit is belonged to.
In actual operation, taking the size of screw hole Broken bolt tooling may be designed as: grooved bit 1 and withdrawing device for broken threaded parts 2
Total length is 500mm, working end outer diameter, interlude outer diameter and the bottom end outer diameter of grooved bit 1 be respectively 11mm, 27mm and
17mm, working end outer diameter, interlude outer diameter and the bottom end outer diameter of withdrawing device for broken threaded parts 2 are respectively 15mm, 29mm and 22mm, Suo Youchang
Degree tolerance is ± 3mm, and all outer diameter tolerances are ± 1mm.It is inserted with drill bit the bottom end of grooved bit 1 and withdrawing device for broken threaded parts 2
Hole connection, thus outer diameter design size is identical.The interlude of the two may also be designed with multi-segment structure.
In addition, a length of 70mm in the bottom end of grooved bit 1, a length of 413mm of interlude, a length of 17mm in working end.Wherein, fracture of wire
