Abstract
Description
Technical Field
[0001] This invention relates to the field of wheel hub processing technology, and in particular to a structure for a precision machining production line for motorcycle wheel hubs. Background Technology
[0002] With the rapid development of the motorcycle industry, the trends of lightweighting, refinement, and high quality in motorcycles are becoming increasingly prominent. As a core load-bearing and appearance component of motorcycles, the machining precision, surface flatness, and appearance quality of aluminum alloy wheels directly determine the vehicle's assembly precision, driving safety, and overall appearance. Motorcycle wheels require higher precision machining standards for surface polishing, deburring, and cleanliness. Defects such as surface burrs, machining scratches, dust residue, and water stains / oxidation must be completely eliminated. Simultaneously, they must adapt to the flexible production needs of multi-category, small-batch, and rapidly iterating production lines. Therefore, stringent requirements are placed on the versatility, machining precision, automation level, and environmental performance of wheel precision machining production lines.
[0003] Existing precision machining production lines for motorcycle wheels still suffer from numerous industry-wide technical shortcomings, making it difficult to meet the demands for high-precision, high-efficiency, and environmentally friendly production. Firstly, traditional wheel grinding fixtures mostly employ fixed, rigid clamps, which can only accommodate wheel sizes. For the diverse wheel sizes of motorcycle models, frequent clamping and equipment readjustment are necessary, resulting in cumbersome changeover processes and low production efficiency. Furthermore, the rigid clamping method easily causes deformation of the aluminum alloy wheel's inner wall and surface scratches, making it difficult to guarantee a high yield rate. Simultaneously, traditional fixtures cannot achieve suspended positioning of the wheel, leaving grinding dead zones in the contact area between the wheel and the conveyor equipment, resulting in incomplete removal of burrs and flash, failing to meet precision machining standards. Secondly, existing wheel grinding dust removal equipment is mostly a fixed-point static negative pressure dust collection structure, with limited dust collection coverage. During the wheel hub grinding process, metal shavings and fine dust splash over a wide area, and the wheel hub has a curved and irregular structure, so static dust collection cannot achieve all-round dust capture. A large amount of dust and debris remain on the wheel hub surface, which can easily cause grinding scratches and reduce processing accuracy. At the same time, dust accumulation in the workshop not only pollutes the working environment, but also poses a safety hazard of dust explosion. In addition, traditional dust removal equipment only has a single dust collection function, and the equipment utilization rate is extremely low. Therefore, this application proposes a precision machining production line structure for motorcycle wheel hubs. Summary of the Invention
[0004] The purpose of this invention is to address the problems in the prior art, such as poor fixture versatility, low grinding accuracy, incomplete dust removal and cleaning, and insufficient automation, and to propose a precision machining production line structure for motorcycle wheel hubs.

A third track frame is fixedly mounted on the mounting platform. A connecting block is slidably mounted on the third track frame. A first reciprocating screw is rotatably mounted on the third track frame and threadedly connected to the connecting block. The connecting block is a hollow structure. A dust suction chamber is fixedly mounted at the bottom of the connecting block. An air pump is fixedly mounted on the mounting platform. An air pipe is fixedly mounted at one end of the air pump, and one end of the air pipe communicates with the connecting block. A filter bag is fixedly mounted at the other end of the air pump.
[0006] Optionally, fixed platforms are fixedly installed on both sides of the conveying roller, and a fourth track frame is fixedly installed on the fixed platforms. A second reciprocating screw is rotatably installed on the fourth track frame, and a slide rod is slidably installed on the fourth track frame. The slide rod is threadedly connected to the second reciprocating screw, and a flow guiding cavity is fixedly installed on the slide rod. Multiple nozzles are fixedly installed at the bottom of the flow guiding cavity. A connecting pipe is fixedly installed at one end of the filter bag, and one end of the connecting pipe communicates with the flow guiding cavity. A first electronic valve is fixedly installed on the connecting pipe, and a fixed pipe is fixedly installed on one side of the connecting pipe. A second electronic valve is fixedly installed on the fixed pipe.
[0007] Optionally, a water storage tank is fixedly installed on one side of the conveying roller, a water pipe is fixedly installed on the water storage tank, a third electronic valve is fixedly installed on the water pipe, and one end of the water pipe is fixedly connected to the guide cavity.
[0008] Optionally, a first motor is fixedly installed at the bottom of the first track frame, and the output shaft of the first motor is fixedly connected to the first threaded rod.
[0009] Optionally, a fourth motor is fixedly installed at one end of the slide plate, and the output shaft of the fourth motor is fixedly connected to the second threaded rod. A third motor is fixedly installed at the bottom of the connecting plate, and the output shaft of the third motor is fixedly connected to the turntable.
[0010] Optionally, a second motor is fixedly mounted on the mounting platform, and the output of the second motor is fixedly connected to the grinding roller.
[0011] Optionally, a fifth motor is fixedly installed at one end of the third track frame, and the output shaft of the fifth motor is fixedly connected to the first reciprocating lead screw.
[0012] Optionally, a sixth motor is fixedly installed on the fourth track frame, and the output shaft of the sixth motor is fixedly connected to the second reciprocating lead screw.
[0013] Optionally, a spring is fixedly installed at one end of the positioning plate, and one end of the spring is fixedly connected to the mounting plate.
[0014] Optionally, a collection trough is fixedly installed at the bottom of the conveying roller, and a drain outlet is provided on the collection trough.
[0015] Compared with the prior art, the present invention has the following beneficial technical effects:
[0016] This invention uses a fourth motor to drive a second threaded rod to rotate, causing the second track frame to shift longitudinally. This compresses multiple sets of guide plates, causing them to deflect synchronously. This, in turn, pushes multiple sets of sliders and positioning plates to tensile outwards synchronously, achieving adaptive fitting and fixation to the inner walls of hubs with different inner diameters. Simultaneously, a lifting structure for the first threaded rod and first track frame allows the hub to be lifted and suspended from the conveyor roller groove, completely detaching it from the contact surface of the conveyor roller. A fifth motor then drives a first reciprocating screw to rotate, causing the connecting block and the bottom dust suction chamber to move horizontally and reciprocally at a uniform speed along the third track frame. Combined with the hub's own rotating and grinding motion, this creates an all-around, no-dead-angle capture of fine dust and metal debris generated during the grinding process. An integrated filter bag collection structure enables sealed dust collection and treatment.
[0017] Furthermore, by using the same air pump as the core power unit, and through the logical switching of the first, second, and third electronic valves, the air and water paths are switched to sequentially achieve three major functions: negative pressure dust removal during grinding, high-pressure spray cleaning, and high-pressure airflow drying. Simultaneously, a movable guide chamber and nozzle structure driven by a second reciprocating screw enable full-coverage dynamic operation of cleaning and drying.
[0018] This invention overcomes the shortcomings of traditional wheel hub processing equipment, such as poor versatility, low grinding precision, incomplete dust removal and cleaning, high energy consumption, and easy damage to workpieces. It realizes precision grinding of multi-specification wheel hubs without dead angles, dust-free operation, and integrated washing and drying. Attached Figure Description

[0035] Example 1
[0036] like Figure 1-8As shown, the present invention proposes a precision machining production line structure for motorcycle wheel hubs, including a conveyor roller 1 and a mounting platform 2. The mounting platform 2 is fixedly installed on both sides of the conveyor roller 1. A grinding roller 20 is rotatably installed on the mounting platform 2 for polishing and deburring the wheel hubs on the conveyor roller 1. The conveyor roller 1 has a groove 4. A first track frame 6 is fixedly installed at the bottom of the conveyor roller 1. A first threaded rod 7 is rotatably installed on the first track frame 6. A connecting plate 8 is slidably installed on the first track frame 6. The first threaded rod 7 is threadedly connected to the connecting plate 8. A turntable 18 is rotatably installed on the connecting plate 8. A mounting plate 5 is fixedly installed on the turntable 18. Multiple sliders 12 are symmetrically slidably installed on the mounting plate 5. A positioning plate 19 is slidably installed at one end of each slider 12. A slide plate 14 is fixedly installed, a second track frame 15 is slidably installed on the slide plate 14, a second threaded rod 16 is rotatably installed on the slide plate 14, the second track frame 15 and the second threaded rod 16 are threadedly connected, a plurality of guide plates 13 are symmetrically hinged at the bottom of the second track frame 15, one end of the guide plate 13 is hinged to the slider 12, a third track frame 21 is fixedly installed on the mounting platform 2, a connecting block 22 is slidably installed on the third track frame 21, a first reciprocating screw 34 is rotatably installed on the third track frame 21, the first reciprocating screw 34 is threadedly connected to the connecting block 22, the connecting block 22 is a cavity, a dust suction chamber 24 is fixedly installed at the bottom of the connecting block 22, an air pump 26 is fixedly installed on the mounting platform 2, an air pipe 25 is fixedly installed at one end of the air pump 26, and one end of the air pipe 25 is... One end is connected to the connecting block 22, and the other end of the air pump 26 is fixedly installed with a filter bag 27. The wheel to be ground is placed on the conveying roller 1, and the conveying roller 1 conveys the wheel forward. The wheel hub moves to the slot 4. The first threaded rod 7 is rotated, and the first threaded rod 7 drives the connecting plate 8 to move upward. At this time, the mounting plate 5 moves out of the slot 4 and pushes the wheel hub upward. At this time, the second threaded rod 16 is rotated, and the second threaded rod 16 drives the second track frame 15 to move on the slide plate 14. The bottom of the second track frame 15 presses against the guide plate 13. The guide plate 13 drives the slider 12 to move, so that they separate from each other. The slider 12 drives the positioning plate 19 at one end to move together. The positioning plate 19 contacts the inner wall of the wheel hub. As the second track frame 15 moves continuously, the positioning plate 19 presses against the wheel hub. The mechanism is fixed to accommodate hubs of different sizes. When the hubs are fixed in place, the turntable 18 rotates, causing the mounting plate 5 to rotate, which in turn rotates the hub. Simultaneously, the grinding roller 20 rotates, thoroughly grinding the upper surface of the roller. In conjunction with the activation of the air pump 26, air is extracted from the suction chamber 24, creating negative pressure that draws in the dust generated during grinding. Simultaneously, the first reciprocating screw 34 rotates, causing the connecting block 22 to reciprocate horizontally on the third track frame 21. The connecting block 22 also moves the bottom suction chamber 24, thus fully absorbing the grinding debris. The absorbed debris is then transported through the air pipe 25 to the filter bag 27 for filtration and collection. After grinding is complete, all mechanisms reset.At this point, the wheel hub moves back onto the conveyor roller 1, eliminating the need for manual calibration or tooling changes. It captures fine dust and metal debris generated during the grinding process from all angles, leaving no blind spots. Simultaneously, the integrated filter bag 27 provides a closed-loop dust collection system, enabling rapid switching between production of different product models and significantly enhancing the production line's flexibility.
[0037] Example 2
[0038] like Figure 2 and 9 As shown, fixed platforms 3 are fixedly installed on both sides of the conveyor roller 1. A fourth track frame 33 is fixedly installed on the fixed platform 3. A second reciprocating screw 42 is rotatably installed on the fourth track frame 33. A slide rod 35 is slidably installed on the fourth track frame 33. The slide rod 35 is threadedly connected to the second reciprocating screw 42. A guide cavity 36 is fixedly installed on the slide rod 35. Multiple nozzles are fixedly installed at the bottom of the guide cavity 36. A connecting pipe 28 is fixedly installed at one end of the filter bag 27. One end of the connecting pipe 28 is connected to the guide cavity 36. A first electronic valve 31 is fixedly installed on the connecting pipe 28. A fixed pipe 29 is fixedly installed on one side of the connecting pipe 28. A second electronic valve 30 is fixedly installed on the fixed pipe 29. A water storage tank 37 is fixedly installed on one side of the conveyor roller 1. A water pipe 38 is fixedly installed on the water storage tank 37. A third electronic valve 39 is fixedly installed on the water pipe 38. One end of the water pipe 38 is fixedly connected to the guide cavity 36. After grinding, the hub moves to the bottom of the guide cavity 36, and then the flow is closed. The first electronic valve 31 is opened, the second electronic valve 30 is opened, and the gas drawn in by the air pump 26 is directly discharged from the fixed pipe 29. The third electronic valve 39 is opened, and the water in the water tank 37 is transported from the water pipe 38 to the guide cavity 36, and finally sprayed out from the nozzle at the bottom of the air pump 26. The second reciprocating screw 42 is rotated, and the second reciprocating screw 42 drives the slide bar 35 to make horizontal reciprocating motion on the fourth track frame 33. The slide bar 35 drives the guide cavity 36 to move together, so that the guide cavity 36 can fully clean the polished wheel hub. After cleaning, the third electronic valve 39 and the second electronic valve 30 are closed, and the first electronic valve 31 is opened. At this time, the gas drawn in by the air pump 26 enters the guide cavity 36 from the connecting pipe 28 and is then sprayed out from the nozzle to fully dry the cleaned wheel hub. This reduces the cost of equipment purchase, installation and subsequent maintenance, and also reduces the standby and operating energy consumption of the equipment. Compared with the traditional independent equipment production line, the overall energy consumption is reduced by more than 30%, which has good energy-saving benefits.
[0039] Example 3
[0040] like Figure 4-9As shown, a first motor 9 is fixedly installed at the bottom of the first track frame 6, and the output shaft of the first motor 9 is fixedly connected to the first threaded rod 7. A fourth motor 17 is fixedly installed at one end of the slide plate 14, and the output shaft of the fourth motor 17 is fixedly connected to the second threaded rod 16. The fourth motor 17 drives the second threaded rod to rotate. A third motor 11 is fixedly installed at the bottom of the connecting plate 8, and the output shaft of the third motor 11 is fixedly connected to the turntable 18. The third motor 11 drives the turntable 18 to rotate. A second motor 10 is fixedly installed on the mounting platform 2, and the output shaft of the second motor 10 is fixedly connected to the grinding roller 20. The second motor 10 drives the grinding roller 20 to rotate. One end of the third track frame 21 is fixedly installed... A fifth motor 23 is installed, and the output shaft of the fifth motor 23 is fixedly connected to the first reciprocating lead screw 34. The fifth motor 23 drives the first reciprocating lead screw 34 to rotate. A sixth motor 32 is fixedly installed on the fourth track frame 33, and the output shaft of the sixth motor 32 is fixedly connected to the second reciprocating lead screw 42. The sixth motor 32 drives the second reciprocating lead screw 42 to rotate. A spring 40 is fixedly installed at one end of the positioning plate 19, and one end of the spring 40 is fixedly connected to the mounting plate 5. This ensures the stability of the wheel hub and effectively prevents deformation of the inner wall of the aluminum alloy wheel hub. A collection trough 41 is fixedly installed at the bottom of the conveying roller 1 to collect the wastewater after cleaning. A drain outlet is provided on the collection trough 41.
[0041] Working principle: When the wheel hub is pushed upwards, the second threaded rod 16 is rotated. The second threaded rod 16 drives the second track frame 15 to move on the slide plate 14. The bottom of the second track frame 15 presses against the guide plate 13. The guide plate 13 drives the slider 12 to move, separating them from each other. The slider 12 drives the positioning plate 19 at one end to move together. The positioning plate 19 contacts the inner wall of the wheel hub. As the second track frame 15 continues to move, the positioning plate 19 fixes the wheel hub, thus adapting to different sizes of wheels. The wheel hub is fixed. Then, the turntable 18 is rotated, causing the mounting plate 5 to rotate, which in turn rotates the wheel hub. Simultaneously, the grinding roller 20 is rotated to thoroughly grind the upper surface of the roller. In conjunction with starting the air pump 26, the air pump 26 extracts air from the dust suction chamber 24, creating negative pressure in the dust suction chamber 24 to draw in the dust generated during grinding. Simultaneously, the first reciprocating screw 34 is rotated, causing the connecting block 22 to reciprocate horizontally on the third track frame 21. The connecting block 22 then moves the bottom dust suction chamber 24... The system starts moving to fully absorb the grinding debris. The absorbed debris is transported through air pipe 25 to filter bag 27 for filtration and collection. After grinding, all mechanisms reset. At this time, the hub moves back onto the conveyor roller 1. After grinding, the hub moves below the guide cavity 36. At this time, the first electronic valve 31 is closed, the second electronic valve 30 is opened, and the air pumped in by air pump 26 is directly discharged from fixed pipe 29. The third electronic valve 39 is opened, and the water in water tank 37 is transported from water pipe 38 into guide cavity 36. Finally, the water is discharged by… The nozzle at the bottom of the air pump 26 sprays out, and the second reciprocating screw 42 is rotated. The second reciprocating screw 42 drives the slide bar 35 to make horizontal reciprocating motion on the fourth track frame 33. The slide bar 35 drives the guide cavity 36 to move together, so that the guide cavity 36 can fully clean the polished wheel hub. After cleaning, the third electronic valve 39 and the second electronic valve 30 are closed, and the first electronic valve 31 is opened. At this time, the air pump 26 draws in the air and enters the guide cavity 36 through the connecting pipe 28, and then sprays out from the nozzle to fully dry the cleaned wheel hub.
