Abstract
The utility model discloses an internal thread repairing device. The internal thread repairing device comprises a connecting nut, a repairing tool rest fixedly connected with the connecting nut, and a repairing tool bit fixed on the repairing tool rest through a locking device. The internal thread repairing device is connected with an output shaft of an electric hand drill through the connecting nut in the process of use, the internal thread repairing device is driven by the output shaft of the electric hand drill to rotate, and enables the repairing tool bit to repeatedly contact with the threads of a workpiece with threads to be repaired, and achieves the threads repair. The internal thread repairing device is simple in structure, and convenient to use and control.
Description
Technical field
The utility model relates to a kind of thread repairing device, relates in particular to the device that a kind of large parts or the reparation of irregular component internal thread are used.
Background technology
There are plurality of devices and instrument generally to use the spiral connected mode to be fixed in the engineering machinery and are connected, after the long-time use of engineering machinery, the threaded connection place is because stressed excessive or corrosion damage, make connecting thread metaboly occur, can repair to reuse to the screw thread that can repair on the parts, thereby reduce cost of investment.In the engineering mechanical maintenance process, to mechanically internal thread owing to its volume the reason such as large or out-of-shape can't utilize machine tooling, therefore repair extremely inconveniently, have to change parts, cause the parts waste and increase the weight of cost of investment.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, the internal thread prosthetic device that the screw thread reparation is fast and easy to use.
For solving the problems of the technologies described above, the technical solution of the utility model is: the internal thread prosthetic device, comprise the attaching nut, and described attaching nut is fixedly connected with the reparation knife rest, and described reparation knife rest is fixed with the reparation cutter head by locking device.
As preferred technical scheme, described reparation knife rest comprises connecting rod, and described connecting rod one end is fixedly connected with described attaching nut and the other end is connected with screw rod.
As preferred technical scheme, described reparation cutter head comprises the cutterhead that is set on the described screw rod, and described cutterhead is provided with blade, and described blade thickness is less than distance between the internal thread of screw thread repair member.
As to improvement of the technical scheme, described locking device comprises and is positioned at lock washer and the locking nut that described cutterhead both sides are provided with respectively successively on the described screw rod.
Owing to adopted technique scheme, the internal thread prosthetic device comprises the attaching nut, and described attaching nut is fixedly connected with the reparation knife rest, and described reparation knife rest is fixed with the reparation cutter head by locking device; The beneficial effects of the utility model are: utilize the attaching nut to connect the output shaft of electric hand drill during use, under the rotation of output shaft, drive this device and rotatablely move, thereby make the reparation cutter head repeat to contact with the screw thread of screw thread repair member, realize the screw thread reparation, simple in structure, use control convenient.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1-attaching nut; The 2-connecting rod; The 3-screw rod; The 4-cutterhead; The 5-blade; 6-screw thread repair member; The 7-lock washer; The 8-locking nut.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation some example embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.
Internal thread prosthetic device as shown in drawings, this device need be fixed on the electric hand drill in use, with electric hand drill as its power source.This device comprises attaching nut 1, attaching nut 1 is used for connecting the output shaft of electric hand drill, be fixedly connected with the reparation knife rest on the described attaching nut 1, described reparation knife rest is fixed with the reparation cutter head by locking device, wherein said reparation knife rest comprises connecting rod 2, described connecting rod 2 one ends are fixedly connected with described attaching nut 1 and the other end is connected with screw rod 3, and are simple in structure, easy accessibility.
Described reparation cutter head in the present embodiment comprises the cutterhead 4 that is set on the described screw rod 3, described cutterhead 4 is provided with blade 5, described blade 5 thickness are less than distance between the internal thread of screw thread repair member 6, described locking device comprises and is positioned at lock washer 7 and the locking nut 8 that described cutterhead 4 both sides are provided with respectively successively on the described screw rod 3, be used for fixation cutter head 4, prevent that it from moving along screw rod 3, helps to improve the repairing quality of screw thread repair member 6.
In use, this device is fixed on the output shaft of electric hand drill, stretch in the mouth of screw thread repair member repairing cutter head, and be in contact with it and carry out repair and get final product, use electric hand drill to be that as the main cause of the power source of this device the electric hand drill volume is smaller, lighter weight, carry easy to operately, a staff can finish repair, can certainly replace electric hand drill drive the work of this device with power-equipments such as miniature motors.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
