Description

Technical Field

[0001] The invention relates to the technical field of gear ring cleaning devices, and in particular to an auxiliary device for grinding and cleaning a flywheel gear ring of an automobile. Background Art

[0002] The flywheel ring gear assembly is a connecting part that transmits the starter power to the crankshaft. Its main function is to realize the power transmission between the starter and the crankshaft and provide inertia for the engine. The flywheel is a disc with a large rotational inertia. It is installed on the rear flange of the engine crankshaft. There is a ring gear pressed on the outer edge of the flywheel, which can mesh with the drive gear of the starter. At the same time, behind it is the clutch.

[0003] A mating surface of the clutch. The processing of the flywheel gear ring involves drilling operations. After the drilling is completed, the surface of the flywheel gear ring is adhered to a lot of drilling debris. The debris is adsorbed on the surface of the flywheel gear ring and adhered to the gears on the outer periphery of the flywheel gear ring, making it difficult to remove the debris from the gears. Existing gear ring cleaning equipment usually uses a brush to clean the rack part of the gear ring in the up and down or left and right directions, which has the following problems:

[0004] Since the tooth surfaces of the rack of the gear ring have different angles, it is difficult to clean the stubborn debris adhered to the outer periphery of the gear ring if the gear ring is cleaned from only one angle; solid debris is likely to remain in the cleaning brush during the cleaning of the gear ring, and the surface of the gear ring is easily damaged during repeated scraping, but frequent replacement of the cleaning brush results in low cleaning efficiency; in order to save water, some dirty water used to clean the gear ring is reused after filtering out the impurities contained inside, and the debris formed by the filtration accumulates on the mesh surface of the filter for a long time, causing the mesh to be blocked, requiring frequent cleaning of the filter, further reducing the cleaning efficiency of the flywheel gear ring.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 6 As shown, the present invention provides an auxiliary device for grinding and cleaning a flywheel gear ring of an automobile, comprising a cleaning box 1, a cleaning mechanism 2 and a flushing mechanism 3.

[0032] The cleaning mechanism 2 includes a sun gear 203 rotatably arranged at the center of the cleaning box 1, a plurality of planetary gears 205 arranged in a ring array around the sun gear 203 and meshing with the sun gear 203, and a height-adjustable lifting plate 214 installed above the cleaning box 1.

[0033] The inner wall of the cleaning box 1 is rotatably mounted with a toothed disc 201 that meshes with the plurality of planetary gears 205, and the lower end of the toothed disc 201 is connected to a stirring column 204 located above the filter screen 307. The rotation of the planetary gear 205 drives the rotation of the toothed disc 201 and the stirring column 204 connected thereto, promoting the flow of water in the cleaning box 1, preventing debris from clogging the mesh of the filter screen 307, and improving the use efficiency of the device.

[0034] A support frame 215 is provided at one side of the cleaning box 1 , a driving cylinder 216 is vertically mounted on the support frame 215 , and the lifting plate 214 is connected to a downwardly disposed top rod of the driving cylinder 216 .

[0035] A support cover 217 is provided inside the cleaning box 1, and the sun gear 203 is rotatably mounted above the support cover 217 through a bearing 219. The sun gear 203 is driven to rotate by a drive motor 213 provided on the surface. A plurality of support platforms 218 are also provided on the inner wall of the cleaning box 1, and the planetary gears 205 are rotatably mounted on the corresponding support platforms 218.

[0036] A plurality of vertically distributed cleaning brushes 202 are arranged in a circular array around the surface of the sun gear 203 . The plurality of cleaning brushes 202 are detachably mounted on the surface of the sun gear 203 , and the cleaning brushes 202 can be replaced according to specific usage conditions.

[0037] A threaded rod 206 is vertically mounted on the wheel center of the planetary gear 205, and a bearing tray 207 is mounted on the threaded rod 206 through a lead screw nut (not shown in the figure). A first guide column 209 penetrating the bearing tray 207 is arranged below the lifting plate 214, and a rotating ring 210 is rotatably mounted on the outer edge of the bearing tray 207. The gear ring 100 is stacked and placed on the surface of the rotating ring 210. A second guide column 212 penetrating the positioning hole 200 on the gear ring 100 and the rotating ring 210 is vertically arranged on the planetary gear 205. Specifically:

[0038] The support plate 207 is provided with a first guide hole 208 for penetrating the first guide column 209 , and the swivel ring 210 is provided with a second guide hole 211 for penetrating the second guide column 212 .

[0039] The flushing mechanism 3 includes a water inlet cylinder 306, a filter screen 307 disposed inside the cleaning box 1, and a flushing ring pipe 311 disposed below the lifting plate 214. The piston 305 disposed inside the water inlet cylinder 306 is driven to rise and fall by a power mechanism.

[0040] The power mechanism includes an end cam 301 disposed below the sun gear 203, and the end cam 301 is coaxially disposed with the sun gear 203. The end cam 301 is disposed inside the support cover 217. A guide groove 304 is disposed on the top surface of the water inlet cylinder 306, and a guide rod 302 is vertically slidably disposed inside the guide groove 304. A guide wheel 303 in contact with the wheel surface of the end cam 301 is rotatably mounted on the top end of the guide rod 302. The top end of the guide rod 302 is connected to the top surface of the water inlet cylinder 306 through a return spring 315, and the lower end of the guide rod 302 is connected to the piston 305.

[0041] The water inlet cylinder 306 is provided with a water inlet pipe 309 connected to the water tank 308 inside the cleaning box 1 below the filter screen 307 and a water outlet pipe 310 connected to the flushing ring pipe 311. The water inlet pipe 309 is provided with a first one-way valve 313, and the water outlet pipe 310 is provided with a second one-way valve 314. The first one-way valve 313 allows water to enter the water inlet cylinder 306 from the water tank 308 only through the water inlet pipe 309, and cannot flow in the opposite direction. The second one-way valve 314 allows water to flow out of the water inlet cylinder 306 only through the water outlet pipe 310, and cannot flow in the opposite direction.

[0042] A plurality of nozzles 312 are arranged in a circular array on the flushing ring pipe 311 , at least one of the nozzles 312 faces the meshing position of the sun gear 203 and the planetary gears 205 , and the number of the nozzles 312 is greater than the number of the planetary gears 205 .

[0043] The working principle of the device of the present invention is:

[0044] 1. Loading:

[0045] The stacked gear rings 100 are placed above each rotating ring 210 , and the positioning holes 200 on the gear rings 100 are rotated on the second guide posts 212 extending above the rotating rings 210 , so that the multiple gear rings 100 can be cleaned centrally and synchronously.

[0046] The lifting plate 214 is driven down by driving the cylinder 216 , so that the first guide column 209 installed below the lifting plate 214 passes through the first guide hole 208 correspondingly arranged on the wheel surface of the planetary gear 205 .

[0047] 2. Gear ring cleaning:

[0048] The driving motor 213 is started, and the driving motor 213 drives the sun gear 203 to rotate.

[0049] On the one hand, the cleaning brush 202 installed around the sun gear 203 moves in a circular track, and the sun gear 203 drives a number of planetary gears 205 meshing therewith to rotate with their axles as the center. The threaded rod 206 installed on the axle of the planetary gear 205 also rotates accordingly, and the bearing plate 207 mounted on the threaded rod 206 through the lead screw nut performs a vertical lifting movement under the guidance of the first guide column 209, so that the ring gear 100 placed on the rotating ring 210 above the bearing plate 207 will move up and down in the vertical direction. During the lifting process of the ring gear 100, the cleaning brush 202 will brush the rack 300 on the outer ring relative to the vertical direction of the ring gear 100.

[0050] On the other hand, due to the rotation of the planetary gear 205, the ring gear 100 limited above the rotating ring 210 by the second guide column 212 will also rotate synchronously with the planetary gear 205. Therefore, during the rotation of the ring gear 100, the rack 300 of the entire outer ring will be brushed during the rotation. The cleaning brush 202 brushes the rack 300 of the ring gear 100 that rotates and rises at the same time, that is, the cleaning brush 202 can move obliquely relative to the rack 300, and can clean more tooth surfaces of the rack 300, thereby cleaning the stubborn debris adhered to the surface of the rack 300. By setting the forward and reverse rotation of the drive motor 213, cleaning at more angles can also be achieved.

[0051] In addition, the cleaning brush 202 that has washed the ring gear 100 rotates with the sun gear 203 until the side without the ring gear 100 is cleaned by the high-pressure water of the nozzle 312. This prevents debris in the cleaning brush 202 from wearing the surface of the ring gear 100.

[0052] Finally, the wastewater containing debris formed during the flushing process will enter the cleaning box 1, and will flow into the water tank 308 below after being filtered by the filter screen 307. During the rotation of the sun gear 203, the end cam 301 arranged below the sun gear 203 will also rotate accordingly, and the cam surface of the end cam 301 will contact the guide wheel 303 on one side of the guide rod 302. The guide rod 302 will move up and down under the guidance of the guide groove 304, and the piston 305 installed at the lower end of the guide rod 302 will move up and down along the cylinder body of the water inlet cylinder 306. When the piston 305 moves upward, the water inlet cylinder 306 will move upward. When the water inlet cylinder 306 is moved, the internal volume of the water inlet cylinder 306 increases, and a negative pressure is formed inside. The water in the water tank 308 that has been filtered to remove particulate debris will enter the water inlet cylinder 306 through the water inlet pipe 309, and as the end face cam 301 further rotates, the piston 305 moves downward, the volume in the water inlet cylinder 306 decreases, and the water stored in the water inlet cylinder 306 is squeezed along the water outlet pipe 310 into the flushing ring pipe 311, and is sprayed out along the nozzle 312. The above steps can also realize automatic water supply to the nozzle 312 of the flushing mechanism 3, thereby improving the utilization rate of water resources.

[0053] The present invention cooperates between the cleaning box 1, the cleaning mechanism 2 and the flushing mechanism 3. On the one hand, the sun gear 203 can be driven to rotate while the cleaning brush 202 is driven. The cleaning brush 202 brushes the rack 300 of the rotating and simultaneously lifted and lowered ring gear 100, that is, the cleaning brush 202 can move obliquely relative to the rack 300, and can clean more tooth surfaces of the rack 300, thereby cleaning the stubborn debris adhering to the surface of the rack 300; on the other hand, the cleaning brush 202 alternately cleans and acts on the surface of the ring gear 100, which can avoid the debris mixed in the cleaning brush 202 from causing wear on the surface of the ring gear 100; and while realizing the above steps, it can also realize automatic water filling of the nozzle 312 of the flushing mechanism 3 and the floating of debris in the mesh of the filter screen 307, so as to avoid clogging the mesh and improve the utilization rate of water resources. The device has a simple structure and improves the cleaning efficiency of the ring gear 100 as a whole.

[0054] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
