Description

Technical Field

[0001] This utility model relates to the field of cutting tool design technology, and in particular to a metal grinding tool with a self-cleaning structure. Background Technology

[0002] Grinding tools are tools used in metalworking, primarily for grinding, cutting, and removing metal surfaces. These tools are commonly used in manufacturing industries such as machining, mold making, aerospace, and automotive manufacturing. Grinding tools come in various different types.

[0003] A Chinese patent (publication number CN210498410U) discloses a cutting tool in which airflow enters the air intake channel through the air intake groove. The air intake channel delivers the airflow to the first air outlet, the second air outlet, and the third air outlet respectively, to remove the chips remaining on the first and second machining parts. This replaces the prior art of removing residual chips by disassembling the tool. The present invention greatly reduces the time spent removing residual chips, thereby improving work efficiency.

[0004] The above-mentioned technology achieves airflow guidance by opening airflow holes in the blade, which has a certain dust removal effect. However, this technology requires the use of external fans and other equipment to achieve the airflow guidance effect. In actual applications, the blade is relatively small and thin. Therefore, when using external equipment such as fans for airflow guidance, the installation of fans is relatively difficult, which may affect the dust removal efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a metal grinding tool with a self-cleaning structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: it includes a connecting rod, on which an air guide assembly is provided;

[0007] The air guide assembly includes an air guide tube, which is rotatably connected to a connecting rod. The air guide assembly contains blades, and the air guide tube has an air guide opening, which is configured as an inclined hole.

[0008] In a preferred embodiment, a connecting cylinder is fixedly connected to the air guide duct.

[0009] The technical effect of adopting the above-mentioned further solution is that by setting a connecting cylinder, the bottom of the connecting cylinder is fixedly connected to the air guide cylinder, and the cutter head is set at the top opening of the connecting cylinder, the connecting cylinder can play the role of air guide, directing the air generated by the air guide to the cutter head.

[0010] In a preferred embodiment, a cutter head is fixedly connected to the bottom of the inner wall of the air guide tube, the cutter head is provided with ventilation holes, and the inside of the cutter head is provided with a threaded structure.

[0011] The technical effect of adopting the above-mentioned further solution is that by setting a ventilation port on the cutter head, when the air generated in the air guide tube removes dust from the surface of the thread, a small amount of air will pass through the ventilation port on the cutter head and pass through the inside of the cutter head. Since the cutter head is small in size, the air passing through the inside of the cutter head is sufficient to play a certain heat dissipation role. When the cutter head is in use, it will generate heat due to high-speed rotation and friction. Appropriate heat dissipation can extend the service life of the cutter head.

[0012] In a preferred embodiment, the air vent is located on the outer side of the air duct.

[0013] The technical effect of adopting the above-mentioned further solution is that by setting the air guide on the side of the air guide tube, when in use, the rotation of the blade will drive the air guide tube to rotate. The air guide on the air guide tube is opened at an angle, which allows the air guide tube to initially draw in air through the air guide, and then the blades inside increase the wind speed to remove the chips on the blade.

[0014] In a preferred embodiment, three blades are provided, and all three blades are fixedly connected to the inner wall of the connecting rod.

[0015] The technical effect of adopting the above-mentioned further solution is that by setting three blades, the air velocity inside the air guide tube is increased.

[0016] In a preferred embodiment, all three blades are offset from the air guide.

[0017] The technical effect of adopting the above-mentioned further solution is that by setting the blades and the air guide to be misaligned, the blades are prevented from blocking the air guide to draw in air and affecting the cleaning of chips.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, by setting an air guide component and setting the air guide port on the side of the air guide tube, when in use, the rotation of the blade head will drive the air guide tube to rotate. The air guide port on the air guide tube is opened at an angle, which allows the air guide tube to initially draw in air through the air guide port, and then the blades inside increase the wind speed to remove the chips on the blade. Moreover, it does not require external equipment for air guidance, which is quite practical.

[0020] 2. In this utility model, by setting a ventilation port on the cutter head, when the air generated in the air guide tube removes dust from the surface of the thread, a small amount of air will pass through the ventilation port on the cutter head and pass through the inside of the cutter head. Since the cutter head is small in size, the air passing through the inside of the cutter head is sufficient to have a certain heat dissipation effect on the cutter head. When the cutter head is in use, it will generate heat due to high-speed rotation and friction. Appropriate heat dissipation can extend the service life of the cutter head.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1,

[0029] like Figure 1 As shown, a metal grinding tool with a self-cleaning structure includes a connecting rod 1, on which an air guide assembly 2 is provided;

[0030] like Figures 1 to 3 As shown, the air guide assembly 2 includes an air guide tube 22, which is rotatably connected to the connecting rod 1. A blade 21 is connected inside the air guide assembly 2, and an air guide port 23 is provided on the air guide tube 22. The air guide port 23 is set as an inclined hole.

[0031] like Figures 1 to 4As shown, by setting the air guide 23 on the side of the air guide tube 22, when the blade head 4 rotates, it will drive the air guide tube 22 to rotate. The air guide 23 on the air guide tube 22 is opened at an angle. This allows the air guide tube 22 to initially draw in air through the air guide 23, and then the blades 21 inside increase the wind speed to remove the chips on the blade. Moreover, it does not require external equipment for air guidance, which is quite practical.

[0032] Example 2,

[0033] like Figure 1 as well as Figure 3 , Figure 4 As shown, a connecting tube 3 is fixedly connected to the air guide tube 22. The bottom of the connecting tube 3 is fixedly connected to the air guide tube 22, and the blade head 4 is set at the top opening of the connecting tube 3. The connecting tube 3 can play the role of guiding the air, directing the air generated by the air guide port 23 to the blade head 4.

[0034] like Figure 1 , Figure 3 , Figure 4 As shown, a cutter head 4 is fixedly connected to the bottom of the inner wall of the air guide duct 22. The cutter head 4 is provided with ventilation holes and has a threaded structure inside. By providing ventilation holes on the cutter head 4, when the air generated inside the air guide duct 22 removes dust from the threaded surface, a small amount of air will pass through the ventilation holes on the cutter head 4 and pass through the inside of the cutter head 4. Since the cutter head 4 is small in size, the air passing through the inside of the cutter head 4 is sufficient to have a certain heat dissipation effect. The cutter head 4 generates heat due to high-speed rotation and friction during use. Proper heat dissipation can extend the service life of the cutter head 4.

[0035] like Figures 1 to 4 As shown, the air guide 23 is opened on the outer side of the air guide tube 22. By setting the air guide 23 on the side of the air guide tube 22, when the blade 4 rotates, it will drive the air guide tube 22 to rotate. The air guide 23 on the air guide tube 22 is opened at an angle. This allows the air guide tube 22 to initially draw in air through the air guide 23, and then the blades 21 inside increase the wind speed to remove the chips on the blade.

[0036] like Figure 1 as well as Figure 3 As shown, there are three blades 21 in total. All three blades 21 are fixedly connected to the inner wall of the connecting rod 1. By setting three blades 21, the wind speed inside the air guide duct 22 is increased.

[0037] like Figure 1 as well as Figure 3As shown, all three blades 21 are offset from the air guide 23. By setting the blades 21 to be offset from the air guide 23, the blades 21 are prevented from blocking the air guide 23 from receiving air and affecting the cleaning of chips.

[0038] Working principle:

[0039] like Figure 1-4 As shown: In use, the air guide tube 22 is provided. Since the air guide tube 22 is rotatably connected to the connecting rod 1, when the cutter head 4 rotates, it will drive the connecting tube 3 and the air guide tube 22 to rotate. When the air guide tube 22 rotates, it is provided with an air guide port 23. The air guide port 23 is obliquely opened on the air guide tube 22. This allows the air guide tube 22 to initially draw in air through the air guide port 23. Then, during the rotation of the air guide tube 22, it will drive the blades 21 to rotate together. The blades 21 can act as fan blades to increase the air speed inside the air guide tube 22. Then, the air generated inside the air guide tube 22 is blown onto the cutter head 4 through the connecting tube 3 to remove the chips on its surface, without the need for other external equipment.

[0040] By setting a vent on the cutter head 4, when the air generated in the air duct 22 removes dust from the threaded surface, a small amount of air will pass through the vent on the cutter head 4 and pass inside the cutter head 4. Since the cutter head 4 is small in size, the air passing through the cutter head 4 is enough to have a certain heat dissipation effect. When the cutter head 4 is in use, it will generate heat due to high-speed rotation and friction. Properly dissipating the heat can extend the service life of the cutter head 4.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
