Description

Technical Field

[0001] This invention belongs to the field of automotive parts processing technology, and in particular relates to a processing equipment for automotive wheel hubs. Background Technology

[0002] The existing patent announcement number CN213858703U discloses a wheel hub polishing device. The document states: "This invention discloses a wheel hub polishing device, including a housing. The housing is enclosed and has a sliding door at the front. A water tank is located at the bottom of the housing's inner cavity, and a matching filter screen is placed at the top of the water tank. A baffle is located in the middle of the housing's inner cavity, and through holes are provided from left to right in the middle. A first support plate is located on the right outer wall of the housing. A first motor is screwed to the upper surface of the support plate. The output end of the first motor extends into the inner cavity of the housing and is equipped with a first turntable. A clamping mechanism is provided inside the first turntable, and a limit fixing block is located at the center of the left side of the first turntable." A water pump is located on the top right side of the chassis. This wheel polishing equipment, in actual use, can fix wheel hubs of different models, achieving polishing of different models. Polishing waste and cooling water can be separated, and the cooling water can be recycled, reducing cooling costs and aiding in wheel polishing operations. While the equipment does achieve good practical results, the water spray does cool the polished area of ​​the wheel hub, but it doesn't easily separate the dust from the wheel hub at corners along with the water flow. In this case, some stubborn dust embedded in the corners will enter the next process along with the wheel hub, affecting the processing of subsequent steps.

[0003] Therefore, existing wheel polishing equipment cannot meet the needs of actual use, so there is an urgent need for improved technology to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a processing equipment for automobile wheel hubs to solve the problems mentioned above.

[0008] Furthermore, a rear abutment piece is fixed to one end of the second slide rail away from the first slide rail. The structure of the rear abutment piece is the same as that of the front abutment piece. A second wire harness passes through the rear abutment piece. The end of the second wire harness is also fixed to the transmission structure. The end of the second wire harness away from the transmission structure is fixed to the second winding roller. The structure of the second winding roller is the same as that of the second slide rail. The second winding roller is fixed to the output shaft of the second motor. The fixed end of the second motor is fixed to the rear abutment piece.

[0009] Furthermore, the first support structure and the second support structure are identical in structure. The second support structure includes a U-shaped support, a fixing plate, and a water collection pipe. A water collection box is embedded inside the U-shaped support. The inner cavity of the water collection box is connected to the inner cavity of the water collection pipe. The inner wall of the fixing plate is fixed to the side wall of the second slide rail. The ends of the two water collection pipes are connected to each other, and a water pipe is fixed at the connection point of the two water collection pipes.

[0010] Furthermore, the first wiping device and the second wiping device have the same structure. The first wiping device includes an electric slide rail, a slide base fixed to the output end of the electric slide rail, an L-shaped base fixed to the top surface of the slide base, a wiping sponge fixed to the inner wall of the L-shaped base, a vibration motor fixed to the outer wall of the wiping sponge, and a support plate fixed to the bottom wall of the electric slide rail. The output end of the vibration motor is fixed to the wiping sponge, and the inner wall of the wiping sponge abuts against the outer wall of the electric slide rail for wiping the powder and debris on the outer wall of the electric slide rail.

[0011] Furthermore, a dust collection structure is detachably connected to the connection part between the first wiping device and the first slide rail. The dust collection structure includes a dust collection fan, an air collection pipe fixed to the receiving end of the dust collection fan, a dust collection box fixed to the end of the air collection pipe, and a filter sheet fixed to the end face of the air collection pipe. The dust collection box is embedded in the connection part between the first wiping device and the first slide rail, and the top surface of the dust collection fan is fixed to the bottom surface of the first slide rail.

[0012] Furthermore, the transmission structure includes a sliding seat slidably connected to the top surface of the first slide rail, a transmission motor fixed to the top surface of the sliding seat, a transmission rod fixed to the output shaft of the transmission motor, and an abutment strip fixed to the outer wall of the transmission rod. The transmission rod is inserted into the middle of the hub body, and the outer wall of the abutment strip abuts against the inner wall of the hub body to increase the friction between the transmission rod and the inner wall of the hub body.

[0013] Furthermore, a pump is fixed to the top surface of the enclosure, and support plates are fixed to both sides of the outer wall of the enclosure. There are four support plates, one of which has a hydraulic rod fixed to its bottom surface, and the other three support plates have telescopic rods fixed to their bottom surfaces.

[0014] Furthermore, an L-tube is fixed to the inner wall of the enclosure, and the top surface of the L-tube is connected to the output end of the pump. The L-tube has holes and is distributed at equal intervals on the inner wall of the enclosure with the pump as the center.

[0015] The present invention has the following beneficial effects:

[0016] In practical use, the external device drives the hub body to be sleeved on the upper part of the transmission structure. Then, the electric slide rail can drive the wiping sponge to wipe the dust on the outer wall of the hub body through the L seat. At this time, the dust on the outer wall of the hub body can be separated from the hub body. After the dust on the outer wall of the hub body is wiped by the wiping sponge, the vibration motor can drive the wiping sponge to vibrate. At this time, the dust on the wiping sponge can be collected inside the dust collection structure under inertia.

[0017] In practical use, the external device drives the hub body to be sleeved on the upper part of the transmission structure. When the output shaft of the transmission motor drives the hub body to rotate through the transmission rod, the outer wall of the hub body can rub against the inner wall of the wiping sponge. At this time, the powder on the outer wall of the hub body can be wiped off by the wiping sponge. When the first winding roller winds the first wire harness, the first wire harness can drive the hub body to move to the left through the transmission structure. When the second winding roller winds the second wire harness, the second wire harness can drive the hub body to move to the right through the transmission structure, thereby realizing the adjustment of the use position of the hub body.

[0018] In practical use, the dust collection boxes are distributed on both sides of the electric slide rail. When the vibration motor drives the wiping sponge to vibrate, the user turns on the dust collection fan. At this time, the dust collection fan can discharge the air inside the dust collection box to the outside through the air collection pipe. The inside of the dust collection box is in a negative pressure state, which can realize the dust shaken off by the wiping sponge to be collected inside the dust collection box.

[0019] In actual use, the pump's output shaft is connected to the inner cavity of the L-tube. When the pump drives the water-wax mixture to be transported into the L-tube, the L-tube can spray the water-wax mixture onto the outer wall of the wheel hub body. At this time, the water-wax mixture can be evenly coated on the wheel hub body. Excess wheel hub body can be collected by the water collection box, which makes it easy to continue using the excess water-wax mixture. Attached Figure Description

The first slide rail 18 is detachably connected to the front end of the second slide rail 5, and the first slide rail 18 and the second slide rail 5 have the same structure. A first wiping device 1 is detachably connected to a portion of the first slide rail 18 near the second slide rail 5, and a second wiping device 12 is detachably connected to a portion of the first slide rail 18 symmetrical to the first wiping device 1. A transmission structure 11 is slidably connected to the first slide rail 18. Spring plungers 25 are connected to the bottom surfaces of both the first slide rail 18 and the second slide rail 5. A wheel hub body is sleeved on the transmission structure 11. The hub body 13 is clamped by the first wiping device 1 and the second wiping device 12 for wiping dust off the hub body 13. A first support structure 3 is detachably connected to one side of the second slide rail 5. A second support structure 19 is detachably connected to a portion of the second slide rail 5 that is symmetrical to the first support structure 3. A cover box 9 is connected to the top surfaces of the first support structure 3 and the second support structure 19 for spraying liquid onto the outer wall of the hub body 13. A front abutment piece 17 is fixed to one end of the first slide rail 18 away from the second slide rail 5. A first wire harness 14 passes through the front abutment piece 17. The end of the first wire harness 14... Fixed to the transmission structure 11, the end of the first wire harness 14 facing away from the transmission structure 11 is fixed to the first winding roller 15. The first winding roller 15 is fixed to the output shaft of the first motor 16, and the fixed end of the first motor 16 is fixed to the front abutment piece 17. The end of the second slide rail 5 facing away from the first slide rail 18 is fixed with a rear abutment piece 10. The structure of the rear abutment piece 10 is the same as that of the front abutment piece 17. A second wire harness 8 passes through the rear abutment piece 10. The end of the second wire harness 8 is also fixed to the transmission structure 11. The end of the second wire harness 8 facing away from the transmission structure 11 is fixed to the second winding roller 7. The structure of the second winding roller 7 is the same as that of the first motor 16. The first winding roller 15 has the same structure. The second winding roller 7 is fixed to the output shaft of the second motor 6. The fixed end of the second motor 6 is fixed to the rear abutment piece 10. The first support structure 3 and the second support structure 19 have the same structure. The second support structure 19 includes a U-shaped support 191, a fixing piece 192 and a water collection pipe 193. A water collection box 4 is embedded inside the U-shaped support 191. The inner cavity of the water collection box 4 is connected to the inner cavity of the water collection pipe 193. The inner wall of the fixing piece 192 is fixed to the side wall of the second slide rail 5. The ends of the two water collection pipes 193 are connected to each other, and a water pipe is fixed at the connection part of the two water collection pipes 193.

[0033] In practical use, the external device drives the hub body 13 to be sleeved on the upper part of the transmission structure 11. At this time, the output shaft of the second motor 6 drives the second winding roller 7 to rotate. The second winding roller 7 can wind up the second wire harness 8, which can realize that the second wire harness 8 drives the hub body 13 to move on the first slide rail 18 and the second slide rail 5 through the transmission structure 11, thereby changing the position of the hub body 13. When the hub body 13 moves to the position where the first wiping device 1 and the second wiping device 12 are engaged, the output shaft of the transmission motor 112 can pass through the transmission rod 114. The hub body 13 is rotated, allowing the outer wall of the hub body 13 to be wiped by the wiping sponge 106. After wiping, the electric slide rail 103, via the L-shaped seat 105, causes the wiping sponge 106 to separate from the outer wall of the hub body 13. The output shaft of the second motor 6 continues to drive the second winding roller 7 to rotate. At this time, the second wiring harness 8 drives the transmission structure 11 to slide directly below the cover box 9. The bottom surfaces of the first slide rail 18 and the second slide rail 5 are both connected to spring plungers 25, and the output end of the spring plunger 25 passes through the first slide rail 18 and the second slide rail 5. The bottom surface of the slide rail 5 and the sliding seat 113, where they mate with the spring plunger 25, has a circular groove. When the output end of the spring plunger 25 passes through the bottom surface of the first slide rail 18 and the second slide rail 5 and is inserted into the circular groove, the relative position of the sliding seat 113 with the first slide rail 18 and the second slide rail 5 can be fixed. The spring plunger 25 can be a commonly available type. In this document, its function is to fix the relative position of the sliding seat 113 with the first slide rail 18 and the second slide rail 5, thus preventing misalignment when the transmission structure 11 drives the hub body 13 to rotate. In a stable manner, when the pump 20 drives the water wax mixture to be transported into the L-pipe 24, the L-pipe 24 can spray the water wax mixture onto the outer wall of the wheel hub body 13. At this time, the water wax mixture can be evenly applied to the wheel hub body 13. Excess water wax mixture can be collected by the water collection box 4, which can facilitate the continued use of excess water wax mixture. The discharge port of the water collection box 4 is connected to the water wax mixture storage tank through a pipe. At this time, the liquid collected in the water collection box 4 can be discharged into the storage tank, which can facilitate the recycling of water wax mixture.

The output end of the vibration motor 101 is fixed to the wiping sponge 106, and the inner wall of the wiping sponge 106 abuts against the outer wall of the hub body 13 for wiping the dust on the outer wall of the hub body 13.

[0035] In actual use, the external device drives the hub body 13 to be sleeved on the upper part of the transmission structure 11. Then, the electric slide rail 103 can drive the wiping sponge 106 to wipe the dust on the outer wall of the hub body 13 through the L seat 105. At this time, the dust on the outer wall of the hub body 13 can be separated from the hub body 13. After the dust on the outer wall of the hub body 13 is wiped by the wiping sponge 106, the vibration motor 101 can drive the wiping sponge 106 to vibrate. At this time, the dust on the wiping sponge 106 can be collected inside the dust collection structure 2 under inertia.

At this time, the dust collection fan 202 can discharge the air inside the dust collection box 204 to the outside through the air collection pipe 201. The inside of the dust collection box 204 is in a negative pressure state, which can realize the dust shaken off by the wiping sponge 106 is collected inside the dust collection box 204.

The transmission rod 114 is inserted into the middle of the hub body 13, and the outer wall of the abutment strip 111 abuts against the inner wall of the hub body 13 to increase the friction between the transmission rod 114 and the inner wall of the hub body 13.

[0039] When the output shaft of the drive motor 112 drives the hub body 13 to rotate through the transmission rod 114, the outer wall of the hub body 13 can rub against the inner wall of the wiping sponge 106. At this time, the powder on the outer wall of the hub body 13 can be wiped off by the wiping sponge 106. When the first winding roller 15 winds up the first wire harness 14, the first wire harness 14 can drive the hub body 13 to move to the left through the transmission structure 11. When the second winding roller 7 winds up the second wire harness 8, the second wire harness 8 can drive the hub body 13 to move to the right through the transmission structure 11, thereby realizing the adjustment of the usage position of the hub body 13.

The inner wall of the housing 9 is fixed with an L-tube 24, and the top surface of the L-tube 24 is connected to the output end of the pump 20. The L-tube 24 has holes and is distributed at equal intervals around the pump 20 on the inner wall of the housing 9.

[0041] In actual use, the output shaft of the pump 20 is connected to the inner cavity of the L-tube 24. When the pump 20 drives the water wax mixture to be transported into the L-tube 24, the L-tube 24 can spray the water wax mixture onto the outer wall of the wheel hub body 13. At this time, the water wax mixture can be evenly coated on the wheel hub body 13. Excess water wax mixture can be collected by the water collection box 4, which makes it easy for the excess water wax mixture to be reused.
