[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Refer to Figures 1-4, A tool for processing aluminum alloy, including a connecting block 1. A tool rod 2 is slidably connected inside the connecting block 1. A micro-particle tungsten carbide base tool bit 12 is fixedly connected to the outer surface of the tool rod 2. A precision grinding spiral groove 13 is provided on the outer surface of the micro-particle tungsten carbide base tool bit 12. By providing the micro-particle tungsten carbide base tool bit 12, the high wear resistance and strength of the tool can be increased, and at the same time, the hardness of the tool can also be improved. The precision grinding spiral groove 13 can effectively avoid sticking of the tool.

[0025] Two grooves 3 are provided inside the tool rod 2. Two limit rods 4 are slidably connected inside the connecting block 1. One end of each of the two limit rods 4 close to each other extends into the inside of the groove 3. A return spring 14 is provided on the outer surface of each limit rod 4. One end of each of the two return springs 14 away from each other is fixedly connected to the inner wall of the connecting block 1. One end of each of the two return springs 14 close to each other is fixedly connected to the inner wall of the limit rod 4. The return spring 14 can continuously apply pressure to the limit rod 4 by using its own telescopic ability, so that the limit rod 4 has the ability of automatic reset, increasing the convenience when limiting the groove 3, and at the same time, improving the firmness of the limit rod 4 when limiting.

[0026] A lead screw 5 is fixedly connected to the right end of the connecting block 1. One end of each of the two limit rods 4 away from each other is fixedly connected with a retaining ring 15. A limiting ring 16 is fixedly connected to the outer surface of the lead screw 5. The use of the retaining ring 15 can increase the stress area of the limit rod 4, increasing the convenience when it is necessary to pull the limit rod 4. At the same time, the limiting ring 16 can limit the moving distance of the lead screw 5, increasing the protection of the lead screw 5.

[0027] A tool handle 6 is provided on the outer surface of the lead screw 5. The lead screw 5 is threadedly connected with the tool handle 6. Two boosting blocks 17 are fixedly connected to the outer surface of the connecting block 1. A push plate 18 is fixedly connected to one side of each of the two boosting blocks 17 away from each other. Relying on the cooperation of the boosting blocks 17 and the push plates 18, a good stress point can be provided for the connecting block 1, increasing the convenience when it is necessary to rotate the connecting block 1, and improving the convenience in the use process.

[0028] An auxiliary block 7 is rotatably connected to the outer surface of the lead screw 5. Two fixing blocks 8 are fixedly connected to the outer surface of the auxiliary block 7. Each fixing block 8 is slidably connected inside the tool handle 6. An auxiliary bearing 19 is sleeved on the outer surface of the lead screw 5. The auxiliary bearing 19 is embedded inside the auxiliary block 7. The auxiliary bearing 19 can reduce the friction generated when the lead screw 5 rotates, making the lead screw 5 more sensitive when rotating, and at the same time, reducing the wear speed of the lead screw 5 and increasing the durability of the lead screw 5.

[0029] The right end of the lead screw 5 is fixedly connected with a rotating gear 9. Each adjusting lead screw 10 is threadedly connected inside each fixing block 8. The bottom surface of each fixing block 8 is fixedly connected with a stabilizing block 20. Each stabilizing block 20 is slidably connected inside the tool handle 6. The stabilizing block 20 can move simultaneously with the fixing block 8 and use the frictional force generated on the tool handle 6 during its movement to improve the stability of the fixing block 8 during movement and prevent jamming.

[0030] One end of each of the two adjusting lead screws 10 close to each other is fixedly connected with a tooth limit block 11. Each tooth limit block 11 meshes with the rotating gear 9. The outer surface of each adjusting lead screw 10 is sleeved with a rotating bearing 21. One end of the two rotating bearings 21 close to each other is fixedly connected with the side surface of the tooth limit block 11 away from each other. The rotating bearing 21 can reduce the frictional force generated when the adjusting lead screw 10 rotates, make the adjusting lead screw 10 more sensitive when rotating, and at the same time reduce the wear rate of the adjusting lead screw 10 and increase the service life of the adjusting lead screw 10.

[0031] The working principle of the present utility model is as follows: When in use, first install the tool handle 6 at a suitable position, and process the aluminum alloy with the micro-particle tungsten carbide base tool bit 12. At the same time, precision grinding the spiral groove 13 can improve the processing speed and avoid the situation of sticking the tool. When it is necessary to adjust the length of the milling cutter according to the processing depth, pull the two adjusting lead screws 10, thereby driving the tooth limit blocks 11 to move outwards and releasing the meshing relationship with the rotating gear 9. At this time, rotate the connecting block 1 through the boosting block 17 and the pushing plate 18, and drive the lead screw 5 to rotate, so that the lead screw 5 extends outwards, thereby driving the tool handle 6 and the micro-particle tungsten carbide base tool bit 12 to move simultaneously, changing its length. When the lead screw 5 moves, it can drive the auxiliary block 7 to move simultaneously. When the length is adjusted to be appropriate, reverse the adjusting lead screw 10, and then drive the tooth limit block 11 to mesh with the rotating gear 9 again, realizing the ability to adjust the length of the milling cutter, which can be conveniently changed according to the processing depth requirements, effectively increasing the applicability of the aluminum alloy processing tool. When the tool bit is worn and needs to be replaced after long-term use, pull the two limit rods 4 through the retaining ring 15, so that the limit rods 4 are removed from the grooves 3, and the tool rod 2 is not restricted by external objects. At this time, the tool rod 2 can be disassembled and replaced. At the same time, the return spring 14 can continuously apply pressure to the limit rods 4 by using its own telescopic ability, so as to increase the convenience and stability after fixing when fixing the tool rod 2, realizing the ability to conveniently replace the tool rod 2, without consuming a lot of time, not only increasing the applicability of the aluminum alloy processing tool, but also improving the use effect of the aluminum alloy processing tool.
