Description

Technical Field

[0001] The present invention belongs to the technical field of wheel hub processing, and more specifically, relates to a high-efficiency integrated processing device for automobile wheel hubs. Background Art

[0002] Automotive wheel turning is a precision metal cutting process. It utilizes a computer numerically controlled lathe (CNC lathe) or precision multi-axis turning center. Through the relative motion between a high-speed rotating wheel blank and a fixed or mobile carbide or other superhard material cutting tool, the process precisely removes excess material from specific areas of the wheel, achieving the dimensional accuracy, geometric shape precision (such as roundness, flatness, concentricity), and surface finish (roughness) required by the design drawings.

[0003] The Chinese patent publication number is CN112589135A. The power mechanism of this invention is driven by a servo motor driving a transmission gear set, which transmits power to the turntable mechanism via a synchronous belt. This invention solves the problem of multiple cutting precision in wheel hub machining and significantly improves work efficiency.

[0004] The existing turning equipment has the following problems when turning the wheel hub: Waste capture and scattering issues: During the wheel turning process, due to a lack of targeted waste collection design, the unique rotational motion of the wheel causes waste fluids and chips to splash and spread with greater force and over a wider area. The processing area's structure, adapted to the specific characteristics of wheel processing, results in a large amount of waste fluids and chips being scattered unchecked. This not only severely contaminates the workshop floor and surrounding equipment, increasing the difficulty and cost of cleanup, but also leads to extremely low overall recycling efficiency, a chaotic workshop environment, and a negative impact on production order and the working environment.

[0005] Disadvantages of the rough separation process: The existing wheel hub turning waste treatment cannot effectively deal with the special waste conditions generated by wheel hub processing in the rough separation link. The shapes and sizes of the waste chips generated by wheel hub turning are diverse due to the complex structure of the wheel hub. The existing interception device is difficult to effectively block the larger pieces of metal chips mixed in the waste liquid. These large pieces of waste chips enter the subsequent fine filtration process with the waste liquid and are very likely to cause blockage. Especially for the fine filtration equipment under the high-precision requirements of wheel hub processing, once blocked, it affects the purification and recovery of the waste liquid, and also brings difficulties to the separate treatment of irregularly shaped wheel hub waste chips.

[0006] Equipment integration and space occupation issues: In wheel turning workshops, the traditional waste recycling and treatment system is fragmented and bulky. Due to a lack of rational integration of functional modules such as waste liquid diversion and recovery, preliminary separation, metal chip adsorption and scraping collection, waste liquid fine filtration, and temporary waste chip storage, each link operates independently, occupying workshop space. For production scenarios such as wheel hubs, which are large in size and the processing equipment itself occupies a large area, the additional waste treatment system further exacerbates the space shortage problem, resulting in a chaotic equipment layout and poor coordination between functional modules, seriously affecting the efficiency of waste recycling and the smoothness of the overall production process.

[0018] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0019] See also Figures 1-9 The present invention provides an efficient integrated processing equipment for automobile wheel hubs, comprising a turning CNC table 1, a hydraulic expansion mandrel 11, a turning assembly 12 and a turning frame 13. The turning CNC table 1 is fixedly mounted on the side end of the turning frame 13, the hydraulic expansion mandrel 11 is fixedly mounted on the turning CNC table 1, and the turning assembly 12 is fixedly mounted on the turning frame 13. In the manufacturing of the wheel hub, after completing the casting and heat treatment processes of the wheel hub, it is necessary to turn the wheel hub to remove the excess material at a specific part of the wheel hub to achieve the dimensional accuracy, geometric shape accuracy and surface finish required by the design drawings. When turning the wheel hub, the wheel hub blank that has undergone previous processes such as heat treatment, shot peening and rough processing is clamped on this device. The hydraulic expansion mandrel 11 is usually used to adjust the center hole and the back or front of the wheel hub. It is used as a reference for positioning and clamping to ensure firm clamping and high repeat positioning accuracy. After the hydraulic expansion mandrel 11 is clamped, the wheel hub can be rough turned to quickly remove most of the machining allowances on the mounting surface, center hole, bolt hole positioning surface, rim mating surface and other parts. By assembling a carbide tool with good rigidity and strong impact resistance on the turning component 12, a large cutting depth and feed rate are adopted to achieve efficient metal removal. After completing the rough turning, a secondary fine turning can be performed to achieve the ultra-high dimensional accuracy, geometric tolerance and surface finish required by the final design. By assembling a sharp and wear-resistant precision tool on the turning component 12, a small cutting depth, a small feed rate and a high cutting speed are adopted, and the cutting parameters and tool wear state are strictly controlled to ensure surface quality. The turning frame 13 is provided with a recycling mechanism for recycling waste liquid, and the turning frame 13 is provided with a processing mechanism for treating waste liquid. The recycling mechanism includes a turning shield 2, a cooling nozzle 3 and a V-shaped guide plate 4. The processing mechanism includes a coarse separation box 5, a recovery box 6 and a debris box 7. The turning shield 2 is fixedly mounted on the upper end of the turning frame 13, the cooling nozzle 3 is fixedly mounted on the lower end of the turning shield 2, the V-shaped guide plate 4 is fixedly mounted on the upper end of the turning frame 13, the coarse separation box 5 is fixedly mounted on the inner side wall of the turning frame 13, the recovery box 6 is fixedly mounted on the lower end of the coarse separation box 5, the coarse separation box 5 and the recovery box 6 are connected, and the debris box 7 is movably mounted on the side end of the coarse separation box 5. The inner side wall of the turning frame 13 is provided with an oblique guide plate 14, and the inner side of the turning frame 13 is also fixedly mounted with a crossbar 15. A circular groove 16 is provided at the side end portion of the inner side wall of the turning machine frame 13, and a guide plate 21 is fixedly installed at both side ends of the inner side wall of the turning shield 2. Two mounting grooves 22 are penetrated at the lower end portion of the turning shield 2, and transition grooves 23 are fixedly installed on the inner side walls of the two mounting grooves 22. Notches 24 are penetrated at the side ends of the opposite sides of the two transition grooves 23, and oblique pipes 25 are fixedly installed on the inner side walls of the two notches 24. A guide pipe 31 is fixedly installed between the cooling nozzle 3 and the recovery box 6. Regardless of whether rough turning or fine turning is being performed, the cutting head will generate high temperature during the cutting process. Therefore, it is necessary to start the water pump in the recovery box 6 to pump coolant into the guide pipe 31 and spray it out through the cooling nozzle 3 to cool the cutting head on the turning assembly 12 when it is working. The side end of the V-shaped guide plate 4 is penetrated by a card groove 41, and the lower end of the V-shaped guide plate 4 is penetrated by a liquid receiving port 42. When the turning assembly 12 turns the wheel hub blank fixed on the hydraulic expansion mandrel 11, the turning will produce debris. The coolant sprayed by the cooling nozzle 3 will produce cooling waste liquid when passing through the turning assembly 12 and the wheel hub. The V-shaped guide plate 4 is set on the turning frame 13. The waste liquid and waste chips directly generated during turning will fall into the V-shaped guide plate 4 under gravity, and the waste liquid and waste chips are directly collected and enter the roughing process. In the separation box 5, during turning, the splashing waste liquid and waste chips caused by mechanical friction will splash towards the turning shield 2. A guide plate 21 is provided in the turning shield 2. The splashed waste liquid and waste chips will fall onto the guide plate 21 due to gravity and are collected by the guide plate 21 into the transition trough 23. The ends of the two oblique pipes 25 are fixedly installed in the card slot 41. The oblique pipes 25 on the transition trough 23 can guide the waste liquid and waste chips into the V-shaped guide plate 4 and also collect them in the coarse separation box 5, thereby realizing the collection of waste liquid and waste chips. The inner side wall of the rough separation box 5 is fixedly provided with a stainless steel mesh 51, the inner side wall of the circular groove 16 is fixedly provided with a motor 54, the output end of the motor 54 is fixedly provided with a reciprocating screw rod 55, the inner side wall of the rough separation box 5 is slidably provided with a magnetic plate 52, the side end of the magnetic plate 52 is provided with a threaded groove 53, the reciprocating screw rod 55 is threadedly rotatably arranged in the inner side wall of the threaded groove 53, the inner side wall of the rough separation box 5 is further fixedly provided with a triangular scraper 56, the reciprocating screw rod 55 is rotatably arranged in the inner side wall of the horizontal rack 15, the side end of the rough separation box 5 is provided with a side groove 59, and the scrap box 7 is slidably arranged in the inner side wall of the side groove 59. After the waste liquid is recovered into the rough separation box 5, it will pass through the V-shaped guide plate 4 and the inclined guide plate 14 in the turning rack 13 and enter the area of the stainless steel mesh 51 in the rough separation box 5. The stainless steel mesh 51 can preliminarily filter the waste liquid and waste scrap. The waste liquid will continue to fall through the stainless steel mesh 51, and the metal waste scrap will be filtered in the stainless steel mesh 51. The user can start the motor 54 through the infrared remote control device. The motor 54 is started to drive the reciprocating screw rod 55 to rotate. The reciprocating screw rod 55 rotates through the threaded groove 53 to drive the magnetic plate 52 to reciprocally slide in the rough separation box 5. The bottom end of the magnetic plate 52 can adsorb the metal scrap to collect the scrap above the stainless steel mesh 51 at the lower end of the magnetic plate 52. When the reciprocating screw rod 55 drives the magnetic plate 52 to move to the side of the triangular scraper 56, the magnetic plate 52 continues to move and contacts the triangular scraper 56. The triangular scraper 56 contacts the magnetic plate 52 to scrape the metal scrap collected at the bottom of the magnetic plate 52. The scraped scrap is collected in the inner side wall of the scrap box 7. After the turning of the hub is completed, the scrap box 7 can be slid away from the inner side wall of the rough separation box 5 by pulling the L-shaped ear plate 71 to collect the metal scrap in the scrap box 7. A guide column 57 is fixedly installed on the side end of the coarse separation box 5, and an L-shaped fixing frame 58 is fixedly installed between the guide column 57 and the turning frame 13. Two L-shaped ear plates 71 are fixedly installed on the side end of the debris box 7. The side ends of the two L-shaped ear plates 71 are penetrated by a columnar chute 72. The two L-shaped ear plates 71 are slidably installed on the circumferential ends of the two guide columns 57 through the two columnar chute 72. A filter layer 61 is fixedly installed on the inner side wall of the recovery box 6. A liquid adding pipe 62 is provided on the side end of the recovery box 6. After the waste liquid is initially stripped of metal debris, it will fall into the recovery box 6. A filter layer 61 is provided, and the material of the filter layer 61 is stainless steel sintered felt. Its three-dimensional interwoven fiber structure can effectively intercept residual fine metal chips and some suspended oil. At the same time, relying on the inherent corrosion resistance and mechanical strength of the material, the risk of blockage is reduced while ensuring the cleanliness of the coolant recovery. The coolant that has been finely filtered again will be collected in the recovery box 6, and through the water pump in the recovery box 6, it will be pumped into the guide pipe 31 again and sprayed out through the cooling nozzle 3 to achieve recycling. When the coolant in the recovery box 6 is lost due to reciprocating use, new coolant can be added through the liquid filling pipe 62 for use.

[0020] Working principle: The first step is that in the manufacturing of the wheel hub, after completing the casting and heat treatment process of the wheel hub, the wheel hub needs to be turned to remove the excess material of the specific part of the wheel hub to achieve the dimensional accuracy, geometric shape accuracy and surface finish required by the design drawings. When turning the wheel hub, the wheel hub blank that has undergone previous processes such as heat treatment, shot blasting, and rough processing is clamped on this device. A hydraulic expansion mandrel 11 is usually used to position and clamp the center hole and back or front of the wheel hub as a reference to ensure firm clamping and high repeatability. After the hydraulic expansion mandrel 11 is clamped, the wheel hub can be rough turned to quickly remove most of the machining allowances on the mounting surface, center hole, bolt hole positioning surface, rim mating surface, etc. By assembling a rigid and impact-resistant turning assembly 12 Carbide cutting tools with strong rigidity adopt larger cutting depth and feed rate to achieve efficient metal removal. After completing rough turning, secondary fine turning can be performed to achieve the ultra-high dimensional accuracy, geometric tolerance and surface finish required by the final design. By assembling sharp and wear-resistant precision cutting tools on the turning component 12, adopting smaller cutting depth, smaller feed rate and higher cutting speed, strictly controlling cutting parameters and tool wear status to ensure surface quality, whether in rough turning or fine turning, the cutting head will generate high temperature during the cutting process, so it is necessary to start the water pump in the recovery box 6, pump the coolant into the guide pipe 31, and spray it out through the cooling nozzle 3, so as to cool the cutting head on the turning component 12 when it is working.

[0021] In the second step, when the turning assembly 12 turns the wheel hub blank fixed on the hydraulic expansion mandrel 11, the turning will produce debris. The coolant sprayed by the cooling nozzle 3 will produce cooling waste liquid when passing through the turning assembly 12 and the wheel hub. A V-shaped guide plate 4 is set on the turning frame 13. The waste liquid and waste chips directly generated during turning will fall into the V-shaped guide plate 4 under gravity. The waste liquid and waste chips are directly collected and enter the coarse separation box 5. During turning, the waste liquid and waste chips are directly collected due to mechanical friction. The splashed waste liquid and waste chips will splash towards the turning shield 2. A guide plate 21 is provided inside the turning shield 2. The splashed waste liquid and waste chips will fall onto the guide plate 21 due to gravity and be collected by the guide plate 21 into the transition trough 23. The ends of the two oblique pipes 25 are fixedly installed in the card slot 41. The oblique pipes 25 on the transition trough 23 can guide the waste liquid and waste chips into the V-shaped guide plate 4 and also collect them in the coarse separation box 5, thereby realizing the collection of waste liquid and waste chips. The device is provided with a guide plate 21, a transition groove 23, a V-shaped guide plate 4 and a coarse separation box 5. The V-shaped guide plate 4 and the coarse separation box 5 below the processing area directly receive the waste liquid and waste chips generated during the cutting process. The unique rotational motion during wheel turning causes the waste liquid and waste chips to splash and spread with greater force and over a wider range. The design of the guide plate 21 in the turning shield 2 can effectively reduce the splashing and diffusion of waste liquid, and make the waste flow more concentratedly to the V-shaped guide plate 4. The cooperation between the two realizes the capture of the source of waste, reduces scattering, reduces the difficulty of subsequent cleaning, improves the overall recycling efficiency, and helps to keep the environment around the equipment relatively clean. In the third step, after the waste liquid is recovered into the coarse separation box 5, it will pass through the V-shaped guide plate 4 and the inclined guide plate 14 in the turning frame 13 and enter the stainless steel wire mesh 51 area in the coarse separation box 5. The stainless steel wire mesh 51 will perform a preliminary filtration on the waste liquid and waste chips. The waste liquid will continue to fall through the stainless steel wire mesh 51, while the metal waste chips will be filtered in the stainless steel wire mesh 51. The user can start the motor 54 through the infrared remote control device. The start of the motor 54 will drive the reciprocating screw 55 to rotate. The reciprocating screw 55 rotates through the thread groove 53 to drive the magnetic plate 52 to slide back and forth in the coarse separation box 5. The bottom end of the magnetic plate 52 can be The metal debris is adsorbed, so that the debris filtered on the stainless steel wire mesh 51 is adsorbed and collected on the lower end of the magnetic plate 52. When the reciprocating screw 55 rotates and drives the magnetic plate 52 to move to the side of the triangular scraper 56, the magnetic plate 52 continues to move and contacts the triangular scraper 56. The triangular scraper 56 contacts the magnetic plate 52 and scrapes the metal debris collected on the bottom of the magnetic plate 52. The scraped debris will be collected on the inner wall of the debris box 7. After the turning of the wheel hub is completed, the debris box 7 can be driven to slide away from the inner wall of the coarse separation box 5 by pulling the L-shaped ear plate 71 to collect the metal debris in the debris box 7. This device sets a stainless steel wire mesh 51 on the inner wall of the coarse separation box 5 as the first process of waste material treatment after wheel hub turning. Since the waste chips generated by wheel hub turning have complex shapes, the stainless steel wire mesh 51 can effectively intercept large pieces of metal chips mixed in the waste liquid, so that they are initially separated from the waste liquid flow, preventing large pieces of waste chips from entering the subsequent fine filtration process, reducing the risk of clogging of these units, and creating favorable conditions for further purification and recovery of waste liquid and separate treatment of waste chips; This device cooperates with a magnetic plate 52 and a triangular scraper 56. Since the hardness of the hub manufacturing material is high, the metal chips generated by the hub turning process have a high recycling value. The magnetic plate 52 uses magnetic adsorption to effectively separate the metal chips flowing through its surface from the waste liquid. Subsequently, the triangular scraper 56 can scrape off the metal chips adsorbed on the magnetic plate 52 and collect them in the debris box 7. Through physical separation, metal waste chips can be continuously and actively collected, thereby improving the recovery rate and purity of metal chips after hub turning, and facilitating subsequent centralized processing and resource recycling.

[0022] In the third step, after the waste liquid is initially stripped of metal debris, it will fall into the recovery box 6. A filter layer 61 is provided in the recovery box 6. The filter layer 61 is made of stainless steel sintered felt. Its three-dimensional interwoven fiber structure can effectively intercept the remaining fine metal chips and some suspended oil. At the same time, relying on the inherent corrosion resistance and mechanical strength of the material, the risk of clogging is reduced while ensuring the cleanliness of the coolant recovery. The coolant that has been finely filtered again will be collected in the recovery box 6, and through the water pump in the recovery box 6, it will be pumped into the guide pipe 31 again and sprayed through the cooling nozzle 3 for recycling. When the coolant in the recovery box 6 is lost due to reciprocating use, it can be filled with new coolant through the liquid filling pipe 62. This device is equipped with a filter layer 61. After the waste liquid flows through the removal of metal chips, a special filter layer 61 is set according to the characteristics of the wheel hub processing waste liquid. By setting up the filter layer 61, the waste liquid is filtered more finely to remove the residual tiny solid particles, oil stains and special impurities generated during the wheel hub processing. The cleanliness of the waste liquid is improved and can be returned to the coolant circulation system for reuse. In the subsequent wheel hub processing cooling process, it helps to reduce the consumption of fresh coolant and reduce waste liquid discharge and treatment costs. This device is equipped with a V-shaped guide plate 4, a coarse separation box 5, a stainless steel wire mesh 51, a recovery box 6, a filter layer 61 and a debris box 7, and compactly integrates functional modules such as waste liquid diversion and recovery, preliminary separation, metal chip adsorption and scraping collection, waste liquid fine filtration and waste chip temporary storage into the wheel hub turning equipment, avoiding the additional configuration of a large and scattered external system for waste material treatment, reducing the additional wheel hub production workshop space occupied by the entire waste material recycling and processing process, making the wheel hub processing equipment structure more compact and the layout more reasonable, improving the efficiency of recycling and processing, and simplifying the space occupied.
