Description

Technical Field

[0001] The utility model belongs to the technical field of drill bits, and in particular relates to a drill bit which is convenient for self-chip removal. Background Art

[0002] A drill bit is a tool used to drill through holes or blind holes in solid materials, and can expand existing holes. Drill bits can be divided into those for rough machining and those for fine machining. Drill bits for rough machining generally have a large cutting volume.

[0003] At present, some drill bits on the market have chip grooves on their surfaces for spiral material discharge. Since the debris inside the hole is discharged onto the table surface of the drilling area through the chip grooves of the drill bit, it is necessary to manually clean it up later. Also, when the drill bit is pulled out, the debris remaining around the hole groove is easy to fall back into the hole groove. In addition, for handheld electric drills, the instability of handheld electric drills can easily lead to deviations in the angle of the drill bit and cause problems with the quality of opening the hole groove.

[0004] Therefore, a drill bit with convenient self-chip removal is needed to solve the problem in the prior art that the debris inside the drill hole is discharged onto the table surface of the drilling area through the chip removal groove of the drill bit, resulting in the need for subsequent manual cleaning and the residual debris easily falling back into the newly opened hole groove. Utility Model Content

[0005] The utility model aims to provide a drill bit which is convenient for self-chip removal, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drill bit with convenient self-chip removal, comprising a drill bit body, a drilling portion being provided at the lower end of the drill bit body, a lifting guide mechanism being provided on the surface of the drill bit body, the lifting guide mechanism comprising a fixed lifting plate, a waste chip collection barrel, a rotating support and a lifting guide rod, the fixed lifting plate being sleeved and fixed on the surface of the drill bit body, the waste chip collection barrel being provided below the fixed lifting plate, the lifting guide rod being provided between the fixed lifting plate and the waste chip collection barrel, the rotating support being sleeved on the outside of the waste chip collection barrel, and a collection trough being provided inside the waste chip collection barrel.

[0007] It should be noted in the solution that a lifting guide groove is provided through the upper surface of the fixed lifting plate, and one end of the lifting guide rod is slidably inserted into the lifting guide groove of the fixed lifting plate.

[0008] It is further worth noting that the lower end of the lifting guide rod is fixed to the inner bottom wall of the waste collecting barrel, and an anti-slip end block is fixed to the end of the lifting guide rod away from the waste collecting barrel.

[0009] It should be further explained that a rotating convex ring is fixed at the lower edge of the side surface of the waste collection barrel, a rotating ring groove is opened inside the rotating support, and the rotating convex ring is rotatably connected to the rotating ring groove of the rotating support.

[0010] As a preferred implementation, a through opening is opened at the center of the upper end surface of the rotation support, and an anti-slip pad is fixed to the lower end surface of the rotation support.

[0011] As a preferred embodiment, an inlet and outlet are opened at the center of the inner bottom wall of the waste chip collection barrel, the inlet and outlet of the waste chip collection barrel are connected with the through-hole of the rotating support, and the drill body is penetrated through the inlet and outlet and the through-hole.

[0012] As a preferred embodiment, the side surface of the drill body is provided with chip grooves, and the chip grooves are spirally distributed on the surface of the drill body.

[0013] As a preferred embodiment, a mounting portion is fixed to the upper end surface of the drill body, and a mounting hole is formed on one side surface of the mounting portion.

[0014] Compared with the prior art, the drill bit provided by the utility model is convenient for self-chip removal, which has at least the following beneficial effects:

[0015] ⑴ Through the setting of the lifting guide mechanism, when the drill body continuously moves down and implements drilling, the fixed lifting plate descends along the lifting guide rod and guides the screwing direction of the drill body, thereby improving the disadvantage of the drill body's directional deviation under the operation of a handheld electric drill, thereby ensuring the stability of the drill body's long hole opening work and the drilling quality.

[0016] (2) Through the waste chip collection barrel, the chips generated by drilling are driven by the rotation of the drill body to rise continuously along the spirally arranged chip grooves. The chips lifted out of the drilling area will enter the waste chip collection barrel and achieve the purpose of automatic collection, thereby preventing the chips generated by drilling with traditional self-chip removal drills from remaining around the drilling area and falling back after the drill bit is pulled out.

[0027] This solution has the following working process: before use, the drill body 1 is installed on the hand electric drill through the mounting part 3. When in use, the drilling part 2 of the drill body 1 first preliminarily opens a hole groove in the area to be drilled, until the rotating support 8 is stably placed flat on the position to be drilled through the anti-slip pad 10. When the drill body 1 is continuously moved down and drilling is carried out, the fixed lifting plate 5 descends along the lifting guide rod 15 and guides the screwing direction of the drill body 1, thereby improving the disadvantage of the drill body 1 being offset in the direction under the operation of the handheld electric drill, thereby ensuring the stability of the long hole opening work of the drill body 1 and the drilling quality.

[0028] According to the above working process, it can be known that: when the drill body 1 is continuously moved downward and drilling is carried out, the fixed lifting plate 5 descends along the lifting guide rod 15 and guides the screwing direction of the drill body 1, thereby improving the disadvantage of the drill body 1 being offset in the direction when the handheld electric drill is operated, thereby ensuring the stability of the long hole opening work of the drill body 1 and the drilling quality.
