[0022] Please refer to Figures 1 to 5 : A boring tool for machining the outer circle of brake shoes, including a driving seat 1. Two groups of sliding grooves 201 are opened on the bottom side of the driving seat 1. A threaded rod 204 is rotatably connected inside the sliding groove 201. A sliding seat 203 is helically connected to the threaded rod 204. A tool handle 2 is fixedly connected to the bottom side of the sliding seat 203. Two groups of tool seats 3 are installed on the lower side of the tool handle 2. A plurality of sliding grooves 202 are opened on the bottom side of the driving seat 1. The plurality of sliding grooves 202 are slidably connected to the sliding seat 203.

[0023] Among them, the two groups of tool seats 3 can share the cutting force generated during the outer circle machining of the brake shoes (most traditional ones are single tool seats 3), avoiding that a single tool seat 3 will affect the overall service life of the boring tool. When it is necessary to adjust the distance between the two groups of tool seats 3, by rotating the threaded rod 204, the sliding seat 203 can be moved inside the driving seat 1 when the threaded rod 204 rotates. The distance between the two groups of tool seats 3 can be adjusted by the threaded rod 204. The distance control between the tool seats 3 can be adjusted according to the size of the brake shoes.

[0024] Preferably, two groups of adjusting holes 101 are opened on the driving seat 1. The adjusting holes 101 communicate with the sliding grooves 201. One end of the threaded rod 204 is located inside the adjusting hole 101.

[0025] Among them, when it is necessary to rotate the threaded rod 204, it is necessary to extend an external component into the adjusting hole 101 to rotate the threaded rod 204. This setting can prevent the threaded rod 204 from extending to the outside of the driving seat 1 and prevent scratching the external component. Correspondingly, the rotating end of the threaded rod 204 is engraved with a cross groove or a hexagonal groove.

[0026] Preferably, a limiting hole 102 is opened on the driving seat 1. A limiting screw is helically connected inside the limiting hole 102. The limiting screw and the sliding seat 203 are mating components.

[0027] Among them, when it is necessary to fix the position of the sliding seat 203 inside the sliding groove 201, the limiting screw can be rotated to make the limiting screw play a role in pressing against the sliding seat 203. Among them, the limiting hole 102 is arranged in the middle of the threaded rod 204. This position enables the limiting screw to be connected to the sliding seat 203 no matter how the sliding seat 203 moves.

[0028] Preferably, a fine blade 301 and a rough blade 302 are respectively installed on the two groups of tool seats 3. Among them, the rough blade 302 is located below the fine blade 301.

[0029] Among them, the rough blade 302 is coaxially arranged with the fine blade 301. The rough blade 302 can perform rough machining on the brake shoes, while the fine blade 301 can perform fine machining on the brake shoes, enabling the boring tool to complete the boring process at one time and improving the work efficiency.

[0030] Preferably, both the fine blade 301 and the rough blade 302 are rotatably connected to the tool holder 3 through a rotating shaft 303. Connecting grooves 305 are provided on both the fine blade 301 and the rough blade 302. A fastening bolt 304 is connected between the connecting groove 305 and the tool holder 3, and the other end of the fastening bolt 304 is sleeved with a fastening nut.

[0031] Among them, the included angle between the fine blade 301 and the rough blade 302 and the tool holder 3 can be adjusted through the rotating shaft 303, so that the angles of the fine blade 301 and the rough blade 302 can be adjusted, so as to be applicable to different working scenarios; after adjusting the angles of the fine blade 301 and the rough blade 302, the tool holder 3 and the blade are connected through the fastening bolt 304 to fix the angular position between the tool holder 3 and the blade. The connecting groove 305 is arranged in a semi-circular ring shape, so that the blade can rotate (0° - 40°) with the rotating shaft 303 as the axis, and the tool holder 3 and the blade can still be connected through the connecting groove 305.

[0032] Preferably, a connecting seat 4 is fixedly connected to the upper side of the driving seat 1, and a driving rod 401 is fixedly connected to the upper side of the connecting seat 4 through a flange 402.

[0033] Among them, an external driving member is connected through the driving rod 401, so that the driving seat 1 can rotate, thereby completing the boring process.

[0034] Preferably, an installation groove 403 is provided inside the connecting seat 4. The driving rod 401 extends into the installation groove 403 and is fixedly connected with a fixing tooth 404. The fixing tooth 404 is installed inside the installation groove 403, and the two groups of fixing teeth 404 are engaged with each other.

[0035] Among them, the setting of the fixing tooth 404 can make the connection between the connecting seat 4 and the driving rod 401 closer, and can prevent the driving rod 401 from breaking due to excessive torque when driving the connecting seat 4 to rotate.

[0036] Working principle: Two tool holders 2 and a tool holder 3 are installed on the driving seat 1, which can play a role in reaming when machining the outer circle of the brake shoe. The two tool holders 3 can share the cutting force generated during the outer circle reaming of the brake shoe (most traditional ones are a single tool holder 3), avoiding the single tool holder 3 from affecting the overall service life of the boring tool. When it is necessary to adjust the distance between the two tool holders 3, by rotating the threaded rod 204, the sliding seat 203 can move inside the driving seat 1 when the threaded rod 204 rotates, and the distance between the two tool holders 3 can be adjusted through the threaded rod 204. The distance between the tool holders 3 can be adjusted according to the size of the brake shoe.

[0037] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
