Description

Technical Field

[0001] The utility model relates to the field of protection mechanisms, and particularly to a drill bit protection mechanism. Background Art

[0002] Drill bits are usually made of strong metal materials, featuring wear resistance and high strength. Some drill bits are installed on drive motors to drill metal plates. To cool the drill bits during drilling, a spraying method is usually adopted.

[0003] Although the spraying method can cool the drill bits to increase their service life, the rotation of the drill bits will cause waste chips and spraying liquid to splash, increasing the subsequent cleaning intensity.

[0004] To solve the above problems, a drill bit protection mechanism is proposed in this application. Content of the Utility Model

[0005] (I) Purpose of the Utility Model

[0006] To solve the technical problems in the background art, the utility model proposes a drill bit protection mechanism. The utility model is provided with a protection tube to protect the waste chips and spraying liquid generated by the drill bit during drilling, reducing the splashing phenomenon. At the same time, with the use of a scraping mechanism, the inside of the protection tube is scraped for cleaning.

[0007] (II) Technical Solution

[0008] To solve the above problems, the utility model provides a drill bit protection mechanism, including a drill bit, and an installation block is fixedly sleeved on the drill bit;

[0009] A scraping mechanism is rotatably arranged on the installation block;

[0010] A protection tube is slidably sleeved on the scraping mechanism, and a stop block is fixedly connected to the top end of the protection tube;

[0011] A ring cavity is formed at the inner bottom end of the protection tube, and a liquid supply pipe is fixedly communicated with the ring cavity. Spray holes communicated with the ring cavity are formed on the protection tube.

[0012] Preferably, the scraping mechanism includes a ring, which is rotatably sleeved on the outer periphery of the installation block and is slidably sleeved on the inner wall of the protection tube.

[0013] Preferably, a rubber ring is fixedly sleeved on the outer periphery of the ring.

[0014] Preferably, a counterweight block is fixedly installed on the protection tube.

[0015] Preferably, the protection tube is a transparent protection tube.

[0016] Preferably, the spray holes are arranged to incline downward.

[0017] The above technical solution of the present utility model has the following beneficial technical effects:

[0018] Connect the drill bit to the motor. The drill bit is driven by the machinery at the installation location. The protection tube contacts the drilling location. Spray liquid is introduced through the liquid inlet end of the liquid supply pipe. The drill bit rotates under the drive. When the drill bit continuously penetrates into the drilling location, the generated waste chips are blocked by the protection tube. The spray liquid continuously sprays the drill bit at the drilling location. When spraying the drill bit, under the action of the protection tube, the scattered spraying is reduced, and the convenience of subsequent cleaning is increased. At the same time, as the drill bit continuously moves out of the protection, it drives the ring to scrape the inner wall of the protection tube, and at the same time, the inner wall of the protection tube is cleaned.

[0022] To make the purpose, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present utility model.

[0023] As Figure 1-2 shown, a drill bit protection mechanism proposed by the present utility model includes a drill bit 1, and a mounting block 2 is fixedly sleeved on the drill bit 1;

[0024] A scraping mechanism 3 is rotatably arranged on the mounting block 2;

[0025] A protection tube 4 is slidably sleeved on the scraping mechanism 3, and a stop block 5 is fixedly connected to the top end of the protection tube 4;

[0026] A ring cavity is formed at the inner bottom end of the protection tube 4, and the ring cavity is fixedly communicated with a liquid supply pipe 6, and spray holes 7 communicated with the ring cavity are formed on the protection tube 4.

[0027] In an alternative embodiment, the scraping mechanism 3 includes a circular ring 31 which is rotatably sleeved on the outer periphery of the mounting block 2 and is slidably sleeved on the inner wall of the protective tube 4.

[0028] Furthermore, a rubber ring is fixedly sleeved on the outer periphery of the circular ring 31.

[0029] It should be noted that under the action of the rubber ring, the inner wall of the protective tube 4 can be scraped and cleaned.

[0030] In an alternative embodiment, a counterweight is fixedly installed on the protective tube 4.

[0031] It should be noted that the self-weight of the protective tube 4 is greater than the frictional force between the protective tube 4 and the rubber ring, which is beneficial for the relative movement between the drill bit 1 and the protective tube 4 when the drill bit 1 moves upward.

[0032] In an alternative embodiment, the protective tube 4 is a transparent protective tube.

[0033] It should be noted that by setting it as a transparent protective tube, it is beneficial to observe the inside of the protective tube 4.

[0034] In an alternative embodiment, the spray holes 7 are arranged to incline downward.

[0035] It should be noted that the spray holes 7 spray towards the drill bit 1, achieving a cooling effect.

[0036] Furthermore, evenly distributed balls are rotatably sleeved at the bottom end of the protective tube 4.

[0037] Due to the gaps between the balls, it is beneficial for the spraying liquid to flow out.

[0038] In the present utility model, the drill bit 1 is connected to the motor, the drill bit 1 is driven by the machine at the installation location, the protective tube 4 is in contact with the drilling location, the spraying liquid is introduced through the liquid inlet end of the liquid supply pipe 6, the drill bit 1 is driven to rotate. When the drill bit 1 continuously penetrates into the drilling location, the generated waste chips are blocked by the protective tube 4, the spraying liquid continuously sprays the drill bit 1 at the drilling location, sprays the drill bit 1. Under the action of the protective tube 4, the scattered spraying is reduced, the convenience of subsequent cleaning is increased. At the same time, as the drill bit 1 continuously moves out of the protection 4, it drives the circular ring 31 to scrape the inner wall of the protective tube 4, and at the same time, the inner wall of the protective tube 4 is cleaned.

[0039] It should be understood that the above specific embodiments of the present utility model are only used for exemplary illustration or explanation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model. In addition, the appended claims of the present utility model are intended to cover all variations and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
