The problem that a drill bit slips on a circular pipe when the circular pipe is punched by an electric drill in an engineering field is solved. The device is simple in structure, easy to manufacture and low in manufacturing cost, and used materials are convenient to find on a construction site; the use is simple.

Description

TECHNICAL FIELD

[0001] The utility model belongs to engineering construction technical field, especially relate to a drill bit positioning and guiding device for pipe drilling. BACKGROUND

[0002] In the process of engineering construction, the electric drill is often used to drill holes in the pipe. When drilling, the worker usually steps on or holds the pipe with his hand, and then drills holes in the pipe with the electric drill. Because the outer surface of the pipe is relatively smooth, the drill bit often slips on the surface of the pipe when drilling, which not only affects the processing progress, but also affects the processing accuracy and subsequent use. SUMMARY

[0003] In view of the problems existing in the prior art, the utility model provides a drill bit positioning and guiding device for pipe drilling, which can prevent the drill bit from slipping on the pipe.

[0004] The utility model is realized in this way, a drill bit positioning and guiding device for pipe drilling, including a chuck and a clamping seat, the chuck is adopted with the fixed screw is constituted, is equipped with the fixed guiding hole in the center of fixed screw, the clamping seat includes two nuts of coaxial arrangement, two the nut is arranged above and below the pipe respectively, one side of two the nut adopts the arc connecting piece and links up, has the fixed screw in any one the nut screwing.

[0005] The arc connecting piece is made of steel pipe or round steel.

[0006] The center lines of the two nuts pass through the center of the arc connecting piece.

[0007] The utility model has the advantages and technical effects that: by setting the fixed guiding hole on the fixed screw and fixing the fixed screw on the pipe with the clamping seat, the positioning and guiding for the electric drill drilling on the pipe are provided, the drill bit can be prevented from slipping when drilling on the pipe, and the pipe drilling efficiency and drilling quality are improved. The problem of drill bit slipping on the pipe when drilling with the electric drill on the pipe at the engineering site is solved. Moreover, the utility model has simple structure, the materials used are easy to find at the construction site, easy to manufacture and low in cost; and the utility model is easy to use.

[0013] In order to make the utility model purposes, technical solutions and advantages more clearly, the following will be further described in detail with examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0014] Please see Figs. 1-3 A drill bit positioning guide device for round pipe punching, comprising a chuck 1 and a clamping seat 2.

[0015] The chuck 1 is composed of a positioning screw, and a positioning guide hole 3 is arranged in the center of the positioning screw.

[0016] The clamping seat 2 comprises two coaxially arranged nuts 4, 5, the two nuts 4, 5 are arranged above and below the round pipe 7 respectively, and the two nuts 4, 5 are connected by an arc connecting piece 6 on one side.

[0017] The positioning screw is screwed in any one of the nuts 4 or 5.

[0018] In this embodiment, the arc connecting piece 6 is made of steel pipe or round steel, which is convenient to obtain and easy to process. The center lines of the two nuts 4, 5 pass through the center of the arc connecting piece 6, which is convenient to use.

[0019] Application and working principle of the utility model:

[0020] When applied, the clamping seat 2 is clamped on the round pipe 7 to be punched, the position of the positioning screw is adjusted so that it is located above the punching position, and the positioning screw is tightened to the punching position until the end of the positioning screw is tightly pressed against the round pipe 7. At this time, the positioning guide device has been fixed on the round pipe 7.

[0021] The drill bit 9 is installed on the electric drill 8, the drill bit 9 is inserted into the positioning guide hole 3 of the positioning screw of the positioning guide device until it abuts against the punching position of the round pipe 7, and the power supply of the electric drill 8 is turned on. Then the drill bit 9 will punch the round pipe 7 at the set position. Under the action of the positioning guide device, the drill bit will not slip on the round pipe when punching.

[0022] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
