[0030] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0031] like Figures 1-7 As shown, this embodiment provides a gear processing brushing device, including a carrier turntable 1. The bottom of the carrier turntable 1 is rotatably connected to a base 7 via a turntable track 6. A groove 203 is formed in the inner wall of the top of the carrier turntable 1, and a rotating mechanism 2 is installed in the groove 203. A frame 5 is connected to the outer wall of the base 7, and a brushing mechanism 3 is fixed to the top of the frame 5. The rotating mechanism 2 includes a slide cylinder 210 embedded in the groove 203. A slide rod 208 and a spring 209 are installed in the slide cylinder 210. The end of the slide rod 208 is connected to a first pull rope 204. The first pull rope 204 passes through the slide cylinder 210 and the inner wall of the carrier turntable 1 and is connected to a ball head seat 205 on the top of the built-in turntable 206. An outer sleeve 207 is rotatably mounted around the turntable 206. The outer sleeve 207 slides vertically within a straight cylinder 8 fixed to the inner wall of the base 7. A toothed plate 217 is bolted to the bottom of the outer sleeve 207. A residual tooth 218 meshes with one side of the outer wall of the toothed plate 217. A first motor 216 fixed to the inner wall of the base 7 is connected to one side of the residual tooth 218. A sliding shaft 202 is rotatably connected to the end of the slide rod 208 away from the slide cylinder 210 via a bushing. A gear mounting shaft 201 is detachably mounted on the top of the sliding shaft 202, and a rotating tooth 211 is fixed at the bottom. A rack 212 is mounted on the outer side of the rotating tooth 211. The brushing mechanism 3 includes a spray head 302 located directly above the gear mounting shaft 201.

[0032] In the above embodiment, when the rotating disk 1 is filled with the gears to be cleaned, it can rotate on the straight cylinder 8 via the rotating disk track 6, which facilitates the installation of 10 sets of gears to be cleaned. When the first motor 216 drives the residual teeth 218 to rotate, the tooth distribution on the residual teeth 218 can drive the tooth plate 217 to move down in an orderly manner according to the set gap, and then adjust the rotation of the gears to be cleaned through the rotating mechanism 2, so that they rotate in an orderly manner to adjust and align with the tooth gap of the brushing mechanism 3, thereby achieving the purpose of cleaning all tooth gaps.

[0033] The rack 212 is located on one side of the rotating tooth 211, and its initial angle is 45° with the rotating tooth 211. When the rotating tooth 211 moves along the slide groove 203 toward the rack 212, the rack 212 is driven to rotate in the opposite direction by the second pull rope 213, the winding drum 214 and the spiral spring drive disc 215, etc., so that the teeth of the rack 212 and the teeth of the rotating tooth 211 tend to be in the same direction and can mesh, thus driving the rotating tooth 211 to rotate. When the rotating tooth 211 returns in the opposite direction, the rack 212 rotates outward and separates, so as not to cause reciprocating meshing operation to the returning rotating tooth 211.

[0034] The gear mounting shaft 201 is used to fix the gear to be cleaned with a corresponding hole diameter. When the inner diameter of the gear hole is larger than that of the gear mounting shaft 201, an inner liner is required to assist in the installation of the gear.

[0035] A cavity formed in the inner wall of the bearing turntable 1 is provided directly below the chute 203. A winding drum 214 is rotatably connected to the top of the cavity. A second pull rope 213 is wound around the winding drum 214. The top of the second pull rope 213 is fixedly connected to the outer wall of the slide rod 208.

[0036] The bottom of the winding drum 214 is provided with a spiral spring drive disk 215 fixed on the inner wall of the cavity. The spiral spring 209 in the spiral spring drive disk 215 is fixedly connected to the bottom rotating shaft of the winding drum 214, and the rotating shaft passes through the spiral spring drive disk 215 and is fixedly connected to the top of the rack 212. When the winding drum 214 rotates, it drives the spiral spring 209 to wind up. The connecting shaft is released by the spring 209, and the rack 212 can return to its initial position after rotating.

[0037] The scrubbing mechanism 3 also includes a fixed frame 309, and the spray head 302 is fixedly installed on the fixed frame 309 through the support pipe bracket 301, and the external water pipe 310 for connecting the support pipe bracket 301 passes through the fixed frame 309.

[0038] A slide rail 311 is provided on the inner side wall of the fixed frame 309. A support plate 305 is slidably arranged in the slide rail 311. A transmission belt 304 is installed on the support plate 305. The transmission belt 304 is driven by a second motor 306 on the outer side of the bottom of the support plate 305. A slider is connected between the support plate 305 and the slide rail 311.

[0039] An electric push rod 308 is fixed on the other inner wall of the fixed frame 309. A U-shaped clamp 307 is fixedly installed between the output end of the electric push rod 308 and the outer wall of the support plate 305. The U-shaped clamp 307 pushes the support plate 305 along the slide 311 through the electric push rod, thereby adjusting the position of the spray head 302 and the cleaning brush 303.

[0040] A cleaning brush 303 is fitted on the transmission belt 304, and a water collection tank 4 is also provided on the frame 5. The cleaning brush 303 is a hard brush that can enter the gap between the teeth for efficient cleaning.

[0041] The working principle of this device is as follows: When in use, this device is connected to an external power supply and an external control device, and the external water pipe 310 is connected to an external water supply device.

[0042] When gears with different bore diameters are connected to the gear mounting shaft 201, they need to contact the inner bushing for auxiliary installation. After the gears are installed, the bearing turntable 1 is locked and not moved. The tooth gap of the gears extends beyond the outer edge of the bearing turntable 1. At the same time, the U-shaped clamp 307 is pushed by the electric push rod 308 to adjust the position of the cleaning brush 303 so that the bristles can be embedded in the tooth gap.

[0043] The spray head 302 sprays cleaning fluid, covering the top of the gear. The second motor 306 drives the transmission belt 304 to rotate, and at the same time drives the cleaning brush 303 to rotate around to clean the gaps in the gear. Meanwhile, the first motor 216 drives the residual tooth 218 to rotate at a constant speed. The evenly distributed teeth on the residual tooth 218 mesh with the tooth plate 217 in an orderly manner. The tooth plate 217 moves down through the guide in the straight cylinder 8 through the outer sleeve, and pulls the first pull rope 204 at the top. The first pull rope 204 slides in the slide groove 203 at the top of the bearing turntable 1, pulling the slide rod 208 to compress the spring 209 in the slide cylinder 210. The slide rod 208 drives the slide shaft 202 to move in the slide groove 203 through the bushing at the top, causing the gear being cleaned at the top of the slide shaft 202 and the rotating tooth 211 at the bottom to move synchronously.

[0044] When the slide bar 208 moves, it causes the second pull rope 213 connected to the outer wall to be released from the winding drum 214. One end of the winding drum 214 is rotatably mounted on the top of the inner cavity of the bearing turntable 1. Therefore, the winding drum 214 rotates when the second pull rope 213 is released. The spiral spring drive disc 215 is fixedly mounted on the bottom of the inner cavity and is passed through by the bottom shaft of the winding drum 214, connecting to the internal spiral spring 209. The bottom is connected to the rack 212. Therefore, when the bottom shaft rotates with the winding drum 214, the rack 212 also rotates. The rack 212 moves from... The original tilted direction is changed to a horizontal direction, meshing with the teeth of the rotating tooth 211, driving the rotating tooth 211 to rotate at a fixed angle. The rotating tooth 211 drives the top gear being cleaned to rotate at the same angle, achieving the purpose of adjusting the tooth gap position. Then, the first pull rope 204 is reset by the spring 209, the second pull rope 213 is reset by the spiral spring 209 and the winding drum 214, the rack 212 rotates outward away from the rotating tooth 211, no longer meshing and driving, the rotating tooth 211 is reset, the gear being cleaned is reset, and the brushing mechanism 3 cleans the new tooth gap.

[0045] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
