Abstract

The utility model relates to a bolt and screw repairing device, comprising the wrench of a main body and knife boards for cutting press which are connected with the wrench of a main body integrally. The knife boards for cutting press have two knife boards for cutting press, and the knife edges of the two knife boards for cutting press are oppositely arranged, wherein, one knife board for cutting press is clamped at the working end of the wrench of a main body through a central shaft and can be rotated in a radial direction; the other knife board for cutting press is connected with the wrench of a main body into integration through an adjusting threaded rod. The wrench of a main body is provided with an adjusting rotary wheel of a threaded rod. The bolt and screw repairing device can remove the sediment in the screw thread and the rust on the screw thread and correct the deformed screw thread.

Description

Bolt and screw repairing device

The utility model belongs to a kind of bolt, screw is repaired device, particularly at being repairing special requirement and the bolt of size or a kind of design that screw proposes.

General commonly used bolt, screw be in permanent use, or under the situation of improper use, can cause bolt, screw to damage, and especially thread is partly the easiest to be impaired and be out of shape, and causes and can't continue to use.For the problem that this kind bolt, thread damage, the bolt that normally more renews again uses.This mode is out of question certainly for bolt, the screw of general requirements volume production.Yet, for the bolt of unnormalized special size, must according to institute out of the ordinary must requirement, the otherwise designed size is manufactured certain quantity, because of it does not have the quantitatively circulation of production, so bolt can't be changed after impaired at any time, so that machinery stops and causes industrial loss.Under the situation that bolt, screw can't use, must order again or customized, no matter order or customized, required time is extremely of a specified duration, thus, must cause machinery to stop and work delays, its loss is real hardly imaginable.

The purpose of this utility model provides a kind of repairing device that is used for the special requirement screw, utilizes the correcting structure to make the thread of impaired distortion obtain maintenance easily and reuses.

Content of the present utility model comprises: a main body wrench, hob knife plate with the main body wrench is connected as a single entity, hobbing knife plate has one group two, and two hob the knife plate edge of a knife and are oppositely arranged, wherein a slice location knife plate motive axle is placed in main board hand working end, the radially turn of location knife plate; Another sheet positioning knife plate is connected as a single entity by an adjusting screw(rod) and main body wrench, is provided with screw rod on hand at main board and regulates runner; One group of edge of a knife that hobs the location knife plate in the knife plate is to change the triangle edge of a knife, and the top of triangular blade is on the axis of location knife plate axle; Axial strip locating slot is arranged, at main board relative set adjusting screw(rod) locating hole and trip bolt on hand on the adjusting screw(rod).

Characteristics of the present utility model are to be referred from monkey spanner commonly used or alligator wrench main body to make the main body wrench one group of relative knife plate that hobs is set, and utilize to hob knife plate the thread of screw rod, screw is proofreaied and correct and repaired.

Embodiment of the present utility model as shown in drawings, wherein:

Fig. 1 is the design's a stereo appearance figure.

Fig. 2 is the design's structural representation.

Fig. 3 is the design's holder structure schematic diagram.

Fig. 4 is the schematic diagram that the design presses the folder working substance.

Fig. 5 is I-I generalized section of Fig. 4.

Fig. 6 is that the design moves schematic diagram.

Number in the figure is respectively:

10. main body wrench, 11. through holes, 12. screws, 13. gap slot, 14. axle slotted eyes, 20. turns hob cutter hub, 21. the location hobs knife plate, 22. clamping rotary heads, 23. axles, 24. holding screw, 30. positioning hob cutter hub, and 31. positioning hob knife plate, 32. adjusting screw(rod), 321. rectangular locating slots, 40. tightening knobs, 50. screw rod is regulated runner, 100. machined objects, (bolt).

See also Fig. 1, shown in Figure 2, the design mainly is made up of the main body wrench (10) and a pair of cutter hub (20) (30) that hobs of a similar pipe wrench wrench, these main body wrench (10) one ends are established lever, the other end portion that can be in depression, establish a through hole (11) in its protuberance, and depressed part is established slotted eye (14), main body wrench (10) top is provided with a screw rod positioning screw hole (12), and spiral shell is established a tightening knob (40), and the appropriate location in the middle of main body wrench (10) is offered a gap slot (13), establishes a screw rod and regulate runner (50) in groove; In addition, turn hob cutter hub (20) by clamping rotary head (22) folder establish one be provided with the triangle edge of a knife hob knife plate (21), the knife plate (21) of different size and with screw (24) locking, and can be changed according to required in the triangle top on the axis of axle (23).Cutter hub (20) other end is fastened in the main body slotted eye (14) with axle (23), and the Cheng Yike reciprocal state at 15 ° of angles of turn radially.Positioning hob cutter hub (30) have one upright hob knife plate (31).Cutter hub (30) is one affixed one rectangular adjusting screw(rod) (32) simultaneously.Utilize screw rod (32) to penetrate in the main body wrench through hole (11), and regulate and to pass outside the main body (10) after runner (50) screws togather with the screw rod in the gap slot (13).This screw rod (32) top axial is established a rectangular locating slot (321), make the bolt of main body top tightening knob (40) be able to revolve and move in the groove, but and turn fasten screw rod (32) and make positioning knife plate (30) location.

And consult Fig. 3, Fig. 4 and shown in Figure 5, the design's the mode that hobs is to utilize two to hob cutter hub (20), (30) hob knife plate (21), (31) sting the dental groove of double-layered quilt machining object (100) (bolt), as shown in Figure 4, and two knife plates all are provided with the blade of triangle taper, utilize positioning to hob cutter hub (30) and be adjusted to fishbolt (100), and hob knife plate (21), (31) all be sandwiched in the dental groove of bolt thread, for cooperating spinning behaviour, so the turn location hobs cutter hub (20) and is designed to a left side, dextrorotation moves the active state (as shown in Figure 3) at 15 ° of angles, and knife plate becomes the oblique shape of triangle, so time positioning hobs the knife plate (31) that hobs of cutter hub (30) and presses the some place, left side (A) that touches dental groove, the location that turn hobs cutter hub (20) hobs knife plate (21) and then presses respectively along the dental groove gradient and touch in (B) point and (C) point, and form a triangle positioning clamping, then only need grip wrench 1 lever this moment rotates main body, the lines of being docile and obedient the bolt thread is shifted as shown in Figure 6 up or down, and strike off long-pending thing or iron rust in the bolt thread in regular turn, thread with impaired distortion hobs correcting to normal morphology simultaneously, make whole support bolt recover original function, Da Jianyi repairs the purpose of bolt fast.
