The thread repairing device is characterized in that the upper end of the fixed claw is fixedly connected with the adjusting screw rod, the adjusting screw rod is provided with a sliding groove, and the tail end of the fixed claw is connected with the handle. The upper part of the movable claw is drilled with a through hole, the handle is penetrated through the through hole, and a sliding key embedded in the sliding groove and fixed to the movable claw is arranged in the through hole. A circle of steel balls are arranged between an inner groove arranged in an inner wall and an outer groove arranged in the handle, the left side of the lower end of the movable claw is provided with the chasing tool, the right side of the lower end of the movable claw is provided with a spare chasing tool. The utility model can be used for repairing broken bolts without disassembly and has the advantages of simple structure, portability, lightness, convenience for carrying, and low cost.

Description

A kind of screw thread obturator

The utility model relates to a kind of facility, a kind of screw thread obturator of more specifically saying so.

In the industrial production, various machinery equipments and instrument generally adopt bolt, nut to connect part, owing to corroding or colliding with, thereby make bolt, nut major injury, distortion, pull down with metal plate tooth mantle fiber again after the bolt damage to minor diameter at present and re-use, and large diameter bolt can only be pulled down the reparation of usefulness lathe car system, so very time-consuming, and then very difficult to the bolt reparation on the large equipment, therefore adopt the way of changing again mostly, cause very big waste like this.

The purpose of this utility model provides a kind of simple in structure, and is easy to operate, need not to dismantle the screw thread obturator that can repair screw thread.

The purpose of this utility model is realized by following technical scheme.

The utility model is formed by deciding pawl, adjusting screw mandrel, moving pawl, chasing tool and handle, it is characterized in that:

A, describedly decide pawl upper end and be fixed in by steady pin and regulate the screw mandrel front end, the lower end bends inwards;

Have a sliding tray on b, the described adjusting screw mandrel, terminal part is by the handle that is threaded;

C, described moving pawl top are drilled with the through hole of a horizontal direction, handle passes through hole, being provided with the slide key that is fixed on the moving pawl by holding screw in it is embedded in the sliding tray, put a circle steel ball between the annular water jacket that annular inside groove that has on the inwall and handle front end have, left side, moving pawl lower end is equipped with by screw and is fixed chasing tool on it, and the right side is equipped with by screw and is fixed standby chasing tool on it.

During use, the bolt of need reparation placed decide bending place, pawl lower end, again according to waiting that thread form and the tooth of repairing bolt thread are fixed in left side, moving pawl lower end apart from select suitable chasing tool from standby chasing tool, the turn handle moves to left pawl lentamente again, upright chasing tool is run into the high point of screw thread damage location, pull handle and do screw thread and repair and cut, make microfeed and Xiu Qie so repeatedly, repair fully until screw thread.

The utility model has the advantages that the Bolt dismantling that need not damage can carry out the screw thread reparation to the bolt of different size, so reparing process is simple, has saved expenses such as a large amount of dismountings, transportation, time dress.

Another advantage of the present utility model is simple in structure, light and flexible, and is easy to carry, with low cost.

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A view.

Fig. 3 is the B-B view.

Fig. 4 is the handle schematic diagram.

By the following examples, in conjunction with the accompanying drawings, the utility model is done to describe further.

Embodiment:

(referring to Fig. 1,2,3,4) will be processed into that the lower end bends inwards decides pawl 1 upper end and is fixed in by steady pin 6 and regulates screw mandrel 2 front ends.On the adjusting screw mandrel 2 that is processed into, open a sliding tray, handle 5 is fastened to its end by screw thread.The through hole of a horizontal direction is bored on moving pawl 3 tops, handle 5 passes through hole, the slide key 8 that is fixed on the moving pawl 3 by holding screw 7 that is provided with in it is embedded in the sliding tray, 10 of the annular water jackets that the annular inside groove 9 that has on the through-hole wall and handle 5 front ends are had are put a circle steel ball 11 again, when making rotary handle 5, moving pawl 3 along continuous straight runs move, and will move left side, pawl 3 lower ends again and adorn one and have screw 12 to fix chasing tool 4 on it, and the right side is adorned and a stringly fixed standby chasing tool 13 on it by screw.The bolt 14 of need reparation is placed between the chasing tool 4 of deciding pawl bending part and moving pawl, pull handle and can repair its damage screw thread.
