[0022] 1. The cross-device part conveying device realizes the full-range non-contact of the hub bearing and the conveying groove by adding a side air float assembly on the basis of magnetic suspension. This maximally reduces the risk of wear, scratches and pollution, and is especially suitable for hub bearings with extremely high surface quality requirements. The air float assembly can effectively suppress the lateral shaking of the hub bearing during conveying, improving the stability of conveying. Especially in the case of high-speed conveying or external interference, the effect of air float guiding is more obvious.

[0023] 2. The cross-device part conveying device. The hub bearing enters the system through the feeding assembly, is lifted by the first elevator, is grabbed by the mechanical hand and is sent into the demagnetization assembly for demagnetization treatment. The demagnetized hub bearing is sent into the polishing machine through the second elevator. Third elevators are arranged between the processes of polishing, cleaning, rust prevention and heat treatment. After being lifted by the third elevator, the hub bearing is placed into the input end of the next process by the mechanical hand.

[0025] 4. The cross-device part conveying device realizes turning through the rotating feeding disc, avoids problems such as dumping and mispositioning of the hub bearing that may occur when the hub bearing turns on the traditional conveying belt, ensures the stability of conveying. The material clamping part can accurately position the hub bearing, ensuring that it enters the next conveying line in the correct posture, which is conducive to the grabbing and operation of the subsequent automatic equipment.

[0032] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Example 1: This invention discloses a cross-equipment parts conveying device and a conveying process for wheel hub bearing parts, such as... Figure 1 As shown, a cross-equipment parts conveying device is used to sequentially convey wheel hub bearings between a polishing machine 1, a cleaning machine 2, a rust-preventing machine 3, and a heat treatment machine 4 along a wheel hub bearing processing production line. This cross-equipment parts conveying device includes a conveyor frame 5 spanning directly above the polishing machine 1, cleaning machine 2, rust-preventing machine 3, and heat treatment machine 4. A guide rail 6 is provided at the top of the conveyor frame 5, and a robotic arm 7, which can slide along the X, Y, and Z axes, is provided on the guide rail 6 and along the wheel hub bearing processing production line. A feeding assembly 8 and a discharging assembly 9 are respectively provided at the input and output ends of the conveyor frame 5. A first elevator 10 is provided at the output end of the feeding assembly 8. Wheel hub bearings placed on the feeding assembly 8 are conveyed to the interior of the first elevator 10. The first elevator 10 transfers the wheel hub bearing inside upwards, and with the help of the robot arm 7, the wheel hub bearing inside the first elevator 10 is transferred to the interior of the demagnetizing assembly 11. The demagnetizing assembly 11 is fixed on one side of the outer shell of the polishing machine 1, and a second elevator 12 is provided at the bottom output end of the demagnetizing assembly 11. The second elevator 12 is used to guide the demagnetized wheel hub bearing into the interior of the polishing machine 1. A third elevator 13 is provided between the polishing machine 1 and the cleaning machine 2, between the cleaning machine 2 and the rust prevention treatment machine 3, and between the rust prevention treatment machine 3 and the heat treatment machine 4. The third elevator 13 and the robot arm 7 are used to realize the transfer of the wheel hub bearing between each process. Finally, the heat-treated wheel hub bearing is obtained, and the wheel hub bearing is transferred through the discharge assembly 9.

[0034] like Figure 1 As shown, the wheel hub bearing enters the system via the feeding assembly 8, is lifted by the first elevator 10, grasped by the robot arm 7, and fed into the demagnetizing assembly 11 for demagnetization. The demagnetized wheel hub bearing is then fed into the polishing machine 1 via the second elevator 12. A third elevator 13 is installed between the polishing, cleaning, rust prevention, and heat treatment processes. After being lifted by the third elevator 13, the wheel hub bearing is placed at the input end of the next process by the robot arm 7. After all processes, the heat-treated wheel hub bearing leaves the system via the discharge assembly 9. The coordinated work of the robot arm 7 and the elevators reduces manual intervention, achieves automated conveying of the wheel hub bearing, and reduces labor intensity.

[0035] Example 2, as Figure 2As shown, the feeding assembly 8 includes a feeding platform 801, a feeding plate 802 fixedly mounted on the upper surface of the feeding platform 801, a conveyor belt 803 inside the feeding plate 802, and a guide plate 804 outside the conveyor belt 803. There are two guide plates 804, and a guide channel is formed between the two guide plates 804. The hub bearing is placed on the conveyor belt 803 and guided into the guide channel by the conveyor belt 803. At the output of the guide channel, the hub bearing is turned by the baffle 805 set on the upper surface of the feeding plate 802 and guided into the guide groove 806 set on one side of the feeding platform 801.

[0036] like Figure 2 As shown, the hub bearing is first placed on the conveyor belt 803, which provides a continuous and controllable moving platform. The conveyor belt 803 drives the hub bearing into the guide channel formed by two guide plates 804. The function of the guide channel is to restrict the movement direction of the hub bearing, allowing it to move only along the direction of the channel, thereby achieving precise positioning. At the outlet of the guide channel, a baffle 805 set on the upper surface of the feed plate 802 blocks the linear movement of the hub bearing. Due to inertia and the obstruction of the baffle 805, the hub bearing is forced to change direction and turn to the guide groove 806 located on one side of the feed table 801. The function of the guide groove 806 is to collect the hub bearing after turning, facilitating subsequent retrieval or further processing.

[0037] like Figure 2 As shown, the inner surface of the guide plate 804 is further provided with a buffer silicone pad 807. The main function of the buffer silicone pad 807 is to absorb the impact energy generated by the hub bearing during the flow guiding process. When the hub bearing impacts the inner wall of the guide plate 804, the buffer silicone pad 807 deforms, converting the impact force into deformation energy, thereby reducing the direct impact on the hub bearing and the guide plate 804. The silicone material has good damping characteristics, which can effectively reduce the noise generated when the hub bearing impacts the guide plate 804 and improve the working environment. The bottom of the buffer silicone pad 807 is bent inward at a 30° angle. This 30° inward bending design can guide the hub bearing to move towards the center of the flow channel 806 when the hub bearing collides with the guide plate 804, reducing the possibility of the hub bearing deviating from the predetermined path and improving the accuracy and reliability of feeding.

[0038] like Figure 2As shown, specifically, the guide channel 806 is inclined downwards and faces the feeding port on one side of the outer casing of the first elevator 10. This allows the hub bearing to roll inside the guide channel 806 under the influence of gravity and enter the first elevator 10 through the feeding port. The guide channel 806 is inclined downwards, using gravity as the driving force to enable the hub bearing to roll automatically inside the guide channel 806. The shape and inclination angle design of the guide channel 806 ensures that the hub bearing rolls in a predetermined direction and precisely faces the feeding port on the outer casing of the first elevator 10. The hub bearing rolls under the influence of gravity and ultimately enters the first elevator 10 through the feeding port, achieving automatic feeding.

[0039] Example 3, as Figure 3 As shown, after rough machining processes (such as polishing or heat treatment) of wheel hub bearings, the surface of the parts is usually covered with a large amount of oil, metal shavings, and may contain high-temperature residue. Therefore, the internal structure of the discharge assembly 9 should not be exactly the same as that of the feeding assembly 8. Using a conveyor belt 803 for transmission has potential defects at the discharge end, specifically: the conveyor belt 803 is prone to slippage, leading to unexpected collisions of the wheel hub bearings and increasing the risk of parts jamming. These problems not only increase maintenance costs but may also affect the continuity of production. Therefore, the discharge assembly 9 needs a more optimized design to adapt to the characteristics of the parts after rough machining, ensuring the stability and efficiency of the production process.

[0040] like Figure 3 As shown, specifically, the discharge assembly 9 includes a discharge trough 901, which is inclined downwards and positioned at the output port of the heat treatment machine 4. The downward inclination of the discharge trough allows the heat-treated workpiece (such as a wheel bearing) to automatically slide to a designated position using gravity, achieving automated discharge and reducing manual intervention. The discharge trough 901 is directly positioned at the output port of the heat treatment machine 4, ensuring that the workpiece can accurately transition from the heat treatment machine 4 to the discharge trough 901, preventing scattering or deviation, and guaranteeing the continuity and efficiency of discharge. The discharge trough 901 is made of corrosion-resistant and high-temperature-resistant materials, capable of withstanding the high temperature of the heat-treated workpiece and any corrosive media present, ensuring the long-term stable operation and service life of the discharge trough 901.

[0041] like Figure 3As shown, a support 902 is installed on the outer side of the feeding trough 901. A coolant spraying device 903 for rapidly cooling the wheel hub bearing is fixedly installed on the top of the support 902, reducing the temperature of the wheel hub bearing and minimizing the thermal impact on subsequent conveying devices. Specifically, the coolant spraying device 903 includes a storage tank for storing fluorinated liquid. A spray head is located at the bottom of the storage tank, facing the inside of the feeding trough 901. A drain hole is located at the bottom of the feeding trough 901, and a waste liquid collection tank is located directly below the drain hole. The fluorinated liquid is sprayed onto the wheel hub bearing in the feeding trough 901 through the spray head, utilizing the heat absorption property of the fluorinated liquid's evaporation to rapidly reduce the temperature of the wheel hub bearing. The sprayed fluorinated liquid flows down from the bearing surface and is drained away through the drain hole at the bottom of the feeding trough 901. The drained fluorinated liquid is collected in the waste liquid collection tank to prevent environmental pollution or resource waste.

[0042] like Figure 3 As shown, fluorinated fluid has excellent cooling properties, which can quickly reduce the temperature of wheel hub bearings and improve production efficiency. Lowering the temperature of the wheel hub bearings can reduce the thermal impact on subsequent conveying devices, extend equipment lifespan, and reduce failure rates.

[0043] like Figure 3 As shown, a non-contact conveying platform 904 is connected to the bottom output end of the feeding trough 901. A magnetic levitation conveying trough 905 is mounted on the non-contact conveying platform 904. The magnetic levitation conveying trough 905 has a first linear guide 906 and a second linear guide 907. At the bottom of both the first linear guide 906 and the second linear guide 907 of the magnetic levitation conveying trough 905, a superconducting electromagnetic levitation assembly 908 based on magnetic levitation technology is installed. The superconducting electromagnetic levitation assembly 908 uses a superconducting electromagnet and requires a precise control system to maintain the stability of the levitated body (hub bearing). Utilizing magnetic levitation technology achieves non-contact conveying, avoiding direct contact between parts and the conveying device, reducing wear and contamination.

[0044] like Figure 3 As shown, in the first linear guide section 906 and the second linear guide section 907 of the magnetic levitation conveyor 905, the magnetic field force generated by the superconducting electromagnetic levitation component 908 further enhances the levitation height and stability of the wheel hub bearing. The key to the superconducting electromagnetic levitation component 908 is the superconducting electromagnet, which can achieve zero resistance at extremely low temperatures and generate a strong magnetic field. The first linear guide section 906 and the second linear guide section 907 are used to guide the wheel hub bearing along a predetermined path, ensuring the accuracy and stability of the conveying. The entire system requires a precise control system to control the magnetic field strength and direction of the superconducting electromagnetic levitation component 908 to maintain the stable levitation and movement of the wheel hub bearing.

[0045] like Figure 3As shown, this avoids direct contact between the wheel hub bearing and the conveyor device, significantly reducing wear and scratches, and improving the quality and service life of the parts.

[0046] like Figure 3 As shown, the magnetic levitation conveying trough 905 has air-float components 14 based on a high-pressure jet-dried air source on both sides of the first linear guide section 906 and the second linear guide section 907, enabling non-contact conveying of the wheel hub bearing. Specifically, the air-float component 14 includes air holes 1401 on both sides of the magnetic levitation conveying trough 905. A high-pressure jetting component 1402 sprays high-pressure gas onto the surface of the wheel hub bearing through the air holes 1401, forming an air film between the wheel hub bearing and the side of the magnetic levitation conveying trough 905. This air film acts like an air cushion, keeping the wheel hub bearing in a non-contact state with the side wall of the trough, thus achieving frictionless conveying. The air-float component 14 works in conjunction with the superconducting electromagnetic levitation component 908 at the bottom of the magnetic levitation conveying trough 905. The magnetic levitation component mainly provides upward support to levitate the wheel hub bearing; the air-float component 14 mainly provides lateral guiding force and stability to prevent the wheel hub bearing from contacting the side wall.

[0047] like Figure 3 As shown, based on magnetic levitation, the addition of a side air flotation component 14 achieves omnidirectional non-contact between the hub bearing and the conveying trough. This minimizes the risk of wear, scratches, and contamination, making it particularly suitable for hub bearings with extremely high surface quality requirements. The air flotation component 14 effectively suppresses lateral swaying of the hub bearing during conveying, improving conveying stability. The guiding effect of air flotation is even more pronounced, especially during high-speed conveying or in the presence of external interference.

[0048] like Figure 3As shown, the air vents 1401 are arranged in a row on both sides of the first linear guide 906 and the second linear guide 907, and the outlet of the air vents 1401 has a duckbill-shaped structure. The duckbill-shaped structure helps to converge and accelerate the airflow, improving thrust efficiency. The hub bearing forms a guide path inside the magnetic levitation conveying trough 905. The air vents 1401 are inclined towards the guide path of the hub bearing. Dry high-pressure gas is injected through the duckbill-shaped air vents 1401, generating a directional thrust. The inclination of the air vents 1401 towards the guide path of the hub bearing means that the thrust of the injected gas is not only radial but also has an axial component. This axial component directly drives the hub bearing to move along the guide path. The two opposing air vents 1401 generate inclined thrust on the two opposing inner sides of the hub bearing. The radial components of these two thrusts partially cancel each other out, but are still sufficient to form a thin air film between the hub bearing and the inner wall of the magnetic levitation conveying trough 905. The function of this air film is to prevent the wheel hub bearing from directly contacting the groove wall, thereby reducing friction, wear, and contamination. Through the pressure distribution of the air film, it provides damping and stability, preventing the wheel hub bearing from vibrating violently or deviating from its guide path during operation.

[0049] like Figure 3 and Figure 4 As shown, the air flotation assembly 14 also includes a high-pressure jet assembly 1402. One output end of the high-pressure jet assembly 1402 is connected to a first air supply pipe 1403, and the output end of the first air supply pipe 1403 is connected to a main pipe 1404. Several branch pipes 1405 are provided on the main pipe 1404, and the output ends of the branch pipes 1405 are connected to jet heads. The jet heads are located inside the air holes 1401. The high-pressure jet assembly 1402 provides a stable and high-pressure air source, ensuring sufficient gas supply to each jet head. The first air supply pipe 1403, the main pipe 1404, and the branch pipes 1405 form a gas distribution network. The jet head design allows for gas acceleration inside the air holes 1401, causing it to be ejected at a higher speed, thereby generating greater thrust. The shape of the air holes 1401 and the position of the jet heads can precisely control the direction of the airflow, causing it to spray at a predetermined angle, thus achieving optimal propulsion and levitation effects.

[0050] like Figure 4As shown, the magnetic levitation conveyor 905 has an arc-shaped corner section 909, which connects the first straight guide section 906 and the second straight guide section 907. The arc design provides a continuous turning path, avoiding the impact and material accumulation caused by sharp turns. The magnetic levitation conveyor 905 requires a smooth material transition, and the arc-shaped corner provides this smooth transition track. The inner surface of the arc-shaped corner section 909 is provided with a buffer pad 15, the main function of which is to absorb the impact force generated by the material during the turning process. When the material enters the corner, due to inertia, it tends to move along the straight direction, thus impacting the inner side of the corner. The buffer pad 15 can reduce the impact and prevent the material from directly colliding with the hard trough wall. The inner surface of the buffer pad 15 is uniformly provided with flexible scrapers 16, which are inclined towards the guide path. The inclination angle of the scraper 16 determines its guiding effect on the material. When the hub bearing impacts the scraper 16, the inclination angle guides the material to move towards the center of the guide path, thereby assisting it in completing the turning. Moreover, the flexible scraper 16 can effectively scrape off the oil and metal debris adhering to the radial surface of the wheel hub bearing, reducing the amount of debris entering the subsequent conveying device and ensuring the smooth conveying of the wheel hub bearing.

[0051] like Figure 4 As shown, the coordinated action of the arc-shaped corner section 909, the buffer pad 15, and the inclined scraper 16 ensures that the material can smoothly complete the turning process, avoiding problems such as jamming, tilting, or rolling.

[0052] like Figure 4 As shown, the top of the scraper 16 is provided with an upper stop portion 17. The interior of the upper stop portion 17 forms an L-shaped limiting groove. The upper stop portion 17 contacts the wheel hub bearing, and the L-shaped limiting groove strictly limits the movement trajectory of the wheel hub bearing during transport, preventing undesirable upward deviation during rotation and movement. This prevents upward deviation and ensures that the scraper 16 always acts on the surface of the wheel hub bearing at a set angle and pressure. This guarantees the depth and uniformity of scraping and cleaning, avoiding incomplete cleaning or excessive surface scratching. The stable position of the wheel hub bearing and the action of the scraper 16 improve scraping efficiency. It also avoids the need for repeated scraping due to wheel hub bearing movement or displacement, reducing working time.

[0053] like Figure 4 As shown, further, another output end of the high-pressure jet assembly 1402 is connected to a second air supply pipe 18, and the output end of the second air supply pipe 18 is connected to an arc-shaped pipe 19. The arc-shaped pipe 19 is fixed on the magnetic levitation conveying trough 905 by a pipe support frame, and the arc-shaped pipe 19 is located directly above the arc-shaped corner 909. Several branch pipes 20 are provided at the bottom of the arc-shaped pipe 19. The output end of the branch pipe 20 is connected to a nozzle, which faces the inside of the limiting groove and is used to remove the waste material scraped inside the limiting groove.

[0054] like Figure 4 As shown, the high-pressure jet assembly 1402 generates a high-speed airflow through nozzles on the first air supply pipe 1403, the arc-shaped pipe 19, and the branch pipe 20. The arc-shaped pipe 19 is designed to evenly distribute the airflow to all positions of the arc-shaped corner 909, ensuring the coverage area for waste removal. The nozzles face the inside of the limiting groove, directly acting on the scraped waste to provide initial thrust. The high-speed airflow blows the waste away from the limiting groove. Driven by the airflow, the waste gains downward momentum. Simultaneously, under the influence of gravity, the waste accelerates downward. The combination of these two forces makes the waste easier to remove. The bottom of the arc-shaped corner 909 of the magnetic levitation conveyor 905 is equipped with an arc-shaped drain outlet, the shape of which matches the curvature of the corner. This maximizes the collection of waste blown down by the airflow, preventing waste from accumulating or spreading within the conveyor trough. The arc design guides the airflow smoothly, reducing turbulence and resistance at the corner and improving the removal efficiency. The bottom of the arc-shaped sewage outlet is connected to the sewage pipe, which can easily discharge the collected waste into the conveying system and realize the centralized treatment of waste.

[0055] like Figure 4 As shown, the high-pressure airflow combined with the arc-shaped drain outlet can quickly and effectively remove waste from the limiting groove, preventing waste from accumulating at the corner and affecting conveying efficiency and product quality.

[0056] like Figure 4 As shown, a disc groove 21 is provided on the inner ring of the arc-shaped corner portion 909 of the magnetic levitation conveying trough 905. The disc groove 21 and the arc-shaped corner portion 909 are coaxially arranged, and the tangential connection between the disc groove 21 and the magnetic levitation conveying trough 905 forms a material guiding part. A rotatable feeding disc 22 is provided inside the disc groove 21. The outer ring surface of the feeding disc 22 is uniformly provided with arc-shaped and concave clamping parts 23.

[0057] like Figure 4 As shown, when the hub bearing reaches the arc-shaped corner from the first linear guide 906, a smooth transition is achieved through the guide section between the magnetic levitation conveyor 905 and the disc groove 21. The tangential design of the guide section prevents the bearing from colliding or getting stuck when entering the disc groove 21. The feeding disc 22 inside the disc groove 21 rotates, and its outer ring clamping part 23 (arc-shaped concave) can accurately "capture" and fix the floating hub bearing. As the feeding disc 22 rotates, the hub bearing is moved along the circumferential direction by the clamping part 23. When the clamping part 23 rotates the hub bearing to a position aligned with the second linear guide 907, the hub bearing smoothly transitions to the second section of the linear conveyor line to continue the subsequent process.

[0058] like Figure 4As shown, by adjusting the rotation speed of the feeding disc 22 and the size of the clamping part 23, the conveying requirements of wheel hub bearings of different sizes and weights can be met.

[0059] like Figure 4 As shown, the clamping parts 23 are distributed at equal angles around the central axis of the feeding disc 22, and several buffer airbags 24 are provided on the arc-shaped surface of the clamping parts 23 of the feeding disc 22. When the wheel hub bearing falls into the clamping parts 23, the buffer airbags 24 can play a buffering role and absorb the impact force. This can avoid the wheel hub bearing from colliding hard with the clamping parts 23, reducing vibration and noise. The buffer airbags 24 can also help the wheel hub bearing to be better positioned in the clamping parts 23 to a certain extent. After the airbags are compressed, they will generate a certain reaction force, making the wheel hub bearing more stably fixed in the clamping parts 23.

[0060] like ​ As shown, the use of the buffer airbag 24 makes the conveying process gentler and further reduces the risk of damage to the hub bearing, which is especially important for bearings with high surface quality requirements.

[0061] A conveying process for wheel hub bearing parts, based on the aforementioned cross-equipment parts conveying device; the conveying steps include:

[0062] S1: The hub bearing enters the system through the feeding assembly 8, is lifted by the first elevator 10, is grabbed by the robot arm 7 and sent to the demagnetizing assembly 11 for demagnetization, and the demagnetized hub bearing is obtained.

[0063] S2: The demagnetized wheel hub bearing is then sent to the polishing machine 1 through the second elevator 12 to obtain the polished wheel hub bearing;

[0064] S3: The polished wheel hub bearing is fed into the cleaning machine 2 through the third elevator 13, and the cleaned wheel hub bearing is obtained;

[0065] S4: The cleaned wheel hub bearing is sent to the rust prevention treatment machine 3 through the third elevator 13, and the rust prevention treatment wheel hub bearing is obtained.

[0066] S5: The rust-proof wheel hub bearing is fed into the heat treatment machine 4 through the third elevator 13 and the heat-treated wheel hub bearing is obtained.

[0067] S6: The heat-treated wheel hub bearing leaves the system through the discharge assembly 9.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
