Abstract

The utility model relates to a module to drill. The utility model is characterized in that the utility model comprises a fixed plate, a lead sleeve on the fixed plate and a through hole on the lead sleeve; the lead sleeve is fixed in the hole of the fixed plate; one part of the lead sleeve is fixed on the upper part of the fixed plate and the other part is fixed in the lower part of the fixed plate; the shape of the lead sleeve in the lower part of the fixed plate is matched with the hole of the braking screw. When the screw needs to be broken, the screw needs to be fixed by the fixed plate, inserting the lead sleeve into the cutting hole, operator holds an electric drill to make the drill insert into the though hole to cut the screw. Therefore the drill hole will not be deflected; and the utility model can prevent the inner helix damage and the braking of the drill head.

Description

Get silk boring dedicated templates

Affiliated technical field

The utility model relates to a kind of maintenance tool, the fracture specific purpose tool of screw (bolt) of specifically a kind of taking-up.

Background technology

Bolt connection piece is after using after a while, and (as corrosion, stressed excessive etc.) through regular meeting the phenomenon that bolt fractures takes place for some reason.And the break-off portion that will break in screw hole is taken out, and then is a job of wasting time and energy very much.Usually adopt in screw rod centre-drilling hole, insert in the hole with getting screw mandrel then, rotate counterclockwise fracture of wire is taken out.Owing to the screw rod hardness height that breaks in screw, and section out-of-flatness, when holing with hand electric drill, can make drill slipping, be difficult to control, occur boring not just, boring is crooked, injure the hole internal thread, even phenomenon such as the drill bit that occurs fractureing, make fracture of wire be difficult to take out, so that cause whole connector discarded.How overcoming above-mentioned defective as early as possible, then is urgent problem.

Summary of the invention

The utility model is to solve the problems such as taking-up fracture of wire difficulty that prior art exists.

In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is: a kind of silk boring dedicated templates of getting, and it is characterized in that: it comprises a fixed head, is fixed with fairlead on the fixed head, guiding is with through hole.

The fairlead plug-in mounting is fixed in the hole of fixed head, and a fairlead part is on fixed head top, and a part is in the fixed head bottom, and is suitable with the hole of the screw that fractures in its shape of guiding body of fixed head lower part.

The fixed plate body of fairlead side is provided with the fixedly fixing hole of fixed head.

Cylindrical, conical being shaped as of the guiding body of fixed head lower part.

Described fixed head is rectangle, annular or part annular.

The utility model compared with prior art has the following advantages and good effect: 1, when needs are got disconnected screw, the fixed head of this dedicated templates is fixed, the guiding body of fairlead bottom is inserted in the fracture of wire hole, the operator uses electric hand drill, make the through hole in the drilling rod insertion fairlead,, fracture of wire is holed to be the drilling rod guiding, thereby boring can be not crooked, and the phenomenon of also having avoided damaging internal thread, the drill bit that fractures takes place.2, simple in structure, be easy to make, easy to use, improved maintenance efficiency, reduced the percent defective of associated fitting.

The specific embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, dedicated templates of the present utility model is used mark 1 chief representative.In order to lead when holing for fracture of wire, design concept of the present utility model is: it comprises a fixed head 2, is fixed with fairlead 3 on the fixed head 2, and guiding is with through hole 4.Fairlead 3 plug-in mountings are fixed in (welding) hole in the middle of fixed head 2, and fairlead 3 has been divided into two parts up and down like this, and fairlead 3 parts are on fixed head 2 tops; A part is in fixed head 2 bottoms, and is suitable with the hole of the screw that fractures in its shape of guiding body of fixed head 2 lower parts, adopts conical in the present embodiment.Fixed head 2 bodies of fairlead 3 two sides are provided with the fixedly fixing hole 5 of fixed head 2.The shape of fixed head 2 adopts the part annular in the present embodiment.

When need are holed to fracture of wire, the coned face of fairlead 3 is inserted in the fracture of wire hole, the fixing hole of fixed head 2 both sides is enclosed within on the adjacent not disconnected bolt, and use fixed by nut, so just the drilling rod of pistol electric drill can be inserted in the through hole of fairlead, drilling rod is led, thereby reached accurate, the easy to operate purpose of bore position.

Referring to Fig. 4 and Fig. 5, different with a last embodiment is, cylindrical being shaped as of fairlead 3 bodies of fixed head 2 bottoms, remainder is identical.

Certainly, the utility model is not limited to above-mentioned giving an example, and it also comprises many variations or remodeling, and does not exceed essential scope of the present utility model.
