Description

Technical Field

[0001] The present invention relates to the technical field of transfer devices for hub bearing parts, and particularly to a cross-device part conveying device and a conveying process for hub bearing parts. Background Art

[0002] Currently, during the rough machining process of hub bearings, such as after forging or heat treatment, a large amount of oil stains, metal debris, and high-temperature residues are likely to accumulate on the part surface. These conditions frequently cause malfunctions in existing conveying devices during operation, such as conveyor belt slipping and sensor failure, increasing the maintenance cost and thus affecting the continuity and efficiency of production.

[0003] Existing conveying devices for hub bearings, especially those using conveyor belt drive, have obvious defects at the discharge end. For example, the conveyor belt is prone to slipping, which may cause unexpected collisions of hub bearings during transportation. This not only easily increases the risk of wear, scratches, and contamination on the surface of hub bearings, but also the remaining oil stains and debris cause adhesion between hub bearings, thereby increasing the risk of jamming of hub bearing parts.

[0013] Preferably, the coolant spraying device includes a storage tank for storing coolant. The bottom output end of the storage tank is connected to a spray head. The spray head is vertically distributed with respect to the axis of the blanking chute.

[0014] Preferably, a conveying process for hub bearing parts uses the above-mentioned cross-device part conveying device, and includes the following steps: S1: The hub bearing is conveyed to the first elevator through the feeding assembly, and the manipulator transfers the hub bearing to the demagnetization assembly; S2: The demagnetized hub bearing is fed into the polishing machine through the second elevator; S3: The polished hub bearing is sequentially transferred to the cleaning machine, the rust prevention treatment machine and the heat treatment machine through the third elevator; S4: The hub bearing after heat treatment slides into the magnetic levitation conveyor trough through the blanking chute, and the coolant spraying device cools it down. S5: The hub bearing is discharged through the non-contact conveying platform.

[0015] In summary, the present application has the following beneficial effects: 1. For this cross-device part conveying device, by adding a side air flotation component on the basis of magnetic levitation, non-contact in all directions between the hub bearing and the conveyor trough is achieved. This minimizes the risks of wear, scratching, and contamination, especially suitable for hub bearings with extremely high surface quality requirements. The air flotation component can effectively suppress the lateral sway of the hub bearing during conveying, improving the stability of conveying. Especially in the case of high-speed conveying or external interference, the role of air flotation guidance is more obvious.

[0016] 2. For this cross-device part conveying device, the hub bearing enters the system through the feeding component, is lifted by the first elevator, grabbed by the manipulator and sent into the demagnetization component for demagnetization. The demagnetized hub bearing is then sent into the polishing machine by the second elevator. Between processes such as polishing, cleaning, rust prevention treatment, and heat treatment, a third elevator is set. After being lifted by the third elevator, it is placed at the input end of the next process by the manipulator. After all processes, the heat-treated hub bearing leaves the system through the discharging component. The coordinated work of the manipulator and the elevator reduces manual intervention, realizes the automated conveying of the hub bearing, and reduces the labor intensity.

[0017] 3. For this cross-device part conveying device, the combined action of the arc-shaped corner part, the buffer pad, and the inclined scraper ensures that the material can complete the turning smoothly. The scraper can effectively scrape off the residual oil stains and metal chips adhering to the radial surface of the hub bearing, reducing the entry of sundries into the subsequent conveying device, ensuring the smoothness of the hub bearing conveying; avoiding problems such as jamming, tilting, or rolling.

[0018] 4. For this cross-device part conveying device, turning is achieved through the rotating feeding disk, avoiding problems such as tipping and misalignment that may occur when the hub bearing turns on a traditional conveyor belt, ensuring the stability of conveying. The material jamming part can accurately position the hub bearing, ensuring that it enters the next section of the conveying line in the correct posture, which is beneficial for the subsequent automated equipment to grab and operate. The continuously rotating feeding disk can receive and convey the hub bearing uninterruptedly, improving the conveying efficiency and reducing the waiting time.

[0019] 5. The conveying process of hub bearing parts. Based on the above-mentioned cross-device part conveying device, the heat-treated hub bearings slide into the magnetic levitation conveying groove through the blanking groove, and are cooled by the coolant spraying device. Finally, the discharging is completed through the non-contact conveying platform. By cooling first and then with the assistance of air flotation and magnetic levitation, the surface abrasion of the hub bearings during transportation can be effectively reduced. Moreover, through the scraper and the rotatable feeding plate, the oil stains and metal debris on the surface of the hub bearings can be cleaned, and the hub bearings can be driven to ensure the smoothness of transportation.

Detailed Embodiments

[0021] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope 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.

[0022] Example 1, the present invention discloses a cross-device part conveying device and a conveying process for hub bearing parts. As Figure 1 shown, among them, a cross-device part conveying device is used to sequentially convey hub bearings between a polishing machine 1, a cleaning machine 2, an anti-rust treatment machine 3, and a heat treatment machine 4 along the processing production line of the hub bearing. The cross-device part conveying device includes a conveying frame 5. The conveying frame 5 spans directly above the polishing machine 1, the cleaning machine 2, the anti-rust treatment machine 3, and the heat treatment machine 4. And a guide rail 6 is provided on the top of the conveying frame 5. Along the processing production line of the hub bearing, a manipulator 7 that can slide in the X-axis direction, Y-axis direction, and Z-axis direction is provided on the guide rail 6. Feeding components 8 and discharging components 9 are respectively provided at the input end and the output end of the conveying frame 5. A first elevator 10 is provided at the output end of the feeding component 8. The hub bearing placed on the feeding component 8 is conveyed and reaches the inside of the first elevator 10. Through the upward transfer of the hub bearing inside the first elevator 10 and with the help of the manipulator 7, the hub bearing in the first elevator 10 is transferred into the inside of the demagnetization component 11. The demagnetization component 11 is fixed on one side surface of the outer shell of the polishing machine 1. And a second elevator 12 is provided at the bottom output end of the demagnetization component 11. The demagnetized hub bearing is guided into the polishing machine 1 by the second elevator 12. Third elevators 13 are provided between the polishing machine 1 and the cleaning machine 2, between the cleaning machine 2 and the anti-rust treatment machine 3, and between the anti-rust treatment machine 3 and the heat treatment machine 4. By using the third elevator 13 and with the help of the manipulator 7, it is used to realize the transfer of the hub bearing between each process. Finally, the heat-treated hub bearing is obtained, and the transfer of the hub bearing is realized through the discharging component 9.

[0023] As Figure 1 shown, the hub bearing enters the system through the feeding component 8. After being lifted by the first elevator 10, it is grabbed by the manipulator 7 and sent into the demagnetization component 11 for demagnetization treatment. The demagnetized hub bearing is then sent into the polishing machine 1 by the second elevator 12. Third elevators 13 are provided between the processes of polishing, cleaning, anti-rust treatment, and heat treatment. After being lifted by the third elevator 13, it is placed at the input end of the next process through the manipulator 7. After all the processes, the heat-treated hub bearing leaves the system through the discharging component 9. The coordinated work of the manipulator 7 and the elevator reduces manual intervention, realizes the automatic conveying of the hub bearing, and reduces the labor intensity.

[0024] Example 2, as Figure 2As shown, the feeding assembly 8 includes a feeding table 801, a feeding plate 802 is fixedly installed on the upper surface of the feeding table 801, a conveyor belt 803 is provided inside the feeding plate 802, a guide plate 804 is provided on the outer side of the conveyor belt 803, two guide plates 804 are provided, and a guide channel is formed between the two guide plates 804, the hub bearing is placed on the conveyor belt 803, and the hub bearing is guided into the guide channel through the conveyor belt 803, and at the output of the guide channel, it is turned at the baffle 805 arranged on the upper surface of the feeding plate 802, and guided to the guide groove 806 arranged on one side of the feeding table 801.

[0025] like Figure 2 As shown, the hub bearing is first placed on the conveyor belt 803, which provides a continuous and controllable mobile 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 limit the moving direction of the hub bearing so that it can only move along the direction of the channel, thereby achieving precise positioning. At the exit of the guide channel, the baffle 805 arranged on the upper surface of the feed plate 802 will block the linear motion 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 platform 801. The function of the guide groove 806 is to collect the hub bearings after turning, so as to facilitate subsequent use or further processing.

[0026] like Figure 2 As shown, further, the inner surface of the guide plate 804 is provided with a buffer silicone pad 807, and the main function of the buffer silicone pad 807 is to absorb the impact energy generated by the hub bearing during the diversion process. When the hub bearing hits the inner wall of the guide plate 804, the buffer silicone pad 807 will deform, 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 properties, which can effectively reduce the noise generated when the hub bearing hits the guide plate 804 and improve the working environment. The bottom of the buffer silicone pad 807 is bent inward at 30°. The design of the bottom bending inward at 30° can guide the hub bearing to move toward the center direction of the guide groove 806 when the hub bearing collides with the guide plate 804, reduce the possibility of the hub bearing deviating from the predetermined route, and improve the accuracy and reliability of feeding.

[0027] like Figure 2As shown, specifically, the diversion chute 806 slopes downward and faces the feeding port opened on the outer shell of one side of the first elevator 10. Under the action of gravity, the hub bearings roll inside the diversion chute 806 and enter the inside of the first elevator 10 through the feeding port. The diversion chute 806 slopes downward, using gravity as the driving force to enable the hub bearings to automatically roll inside the diversion chute 806. The shape and inclination angle of the diversion chute 806 are designed to ensure that the hub bearings can roll along a predetermined direction and precisely face the feeding port on the outer shell of the first elevator 10. The hub bearings roll under the action of gravity and finally enter the inside of the first elevator 10 through the feeding port, realizing automatic feeding.

[0028] Example 3, as Figure 3 As shown, after the rough machining process (such as polishing or heat treatment) of the hub bearings, a large amount of oil stains, metal debris usually adhere to the part surface, and there may be high-temperature residues. In view of this, the internal structure of the discharging assembly 9 should not be exactly the same as that of the feeding assembly 8. There are potential defects in the driving mode of the conveyor belt 803 at the discharging end. Specifically, the conveyor belt 803 is prone to slipping, resulting in unexpected collisions of the hub bearings and increasing the risk of part jamming. The above problems not only increase the maintenance cost but also may affect the continuity of production. Therefore, the discharging assembly 9 needs to adopt a more optimized design scheme to adapt to the characteristics of the parts after rough machining and ensure the stability and efficiency of the production process.

[0029] As Figure 3 As shown, specifically, the discharging assembly 9 includes a blanking chute 901. The blanking chute 901 slopes downward and is arranged at the output port of the heat treatment machine 4. The blanking chute 901 slopes downward, and under the action of gravity, the heat-treated workpieces (such as hub bearings) can automatically slide to the designated position, realizing automatic discharging and reducing manual intervention. The blanking chute 901 is directly arranged at the output port of the heat treatment machine 4 to ensure that the workpieces can accurately transition from the heat treatment machine 4 to the blanking chute 901, avoiding scattering or deviation and ensuring the continuity and efficiency of discharging. The blanking chute 901 is made of corrosion-resistant and high-temperature-resistant materials, which can withstand the high temperature of the workpieces after heat treatment and the possible corrosive media, ensuring the long-term stable operation and service life of the blanking chute 901.

[0030] As Figure 3As shown in the figure, a bracket 902 is provided outside the blanking chute 901. At the top of the bracket 902, a coolant spraying device 903 for quickly cooling the hub bearing is fixedly installed to reduce the temperature of the hub bearing and reduce the thermal impact on the subsequent conveying device. Specifically, the coolant spraying device 903 includes a storage tank for storing fluorinated liquid. A spray head is provided at the bottom of the storage tank, and the spray head faces the inside of the chute body of the blanking chute 901. Drainage holes are provided at the bottom of the chute body of the blanking chute 901, and a waste liquid collection tank is provided directly below the drainage holes of the blanking chute 901. The fluorinated liquid is sprayed onto the hub bearing in the blanking chute 901 through the spray head, and the physical property of the evaporation heat absorption of the fluorinated liquid is utilized to quickly reduce the temperature of the hub bearing. The sprayed fluorinated liquid will flow down from the bearing surface and be drained away through the drainage holes at the bottom of the blanking chute 901. The drained fluorinated liquid is collected by the waste liquid collection tank to prevent environmental pollution or resource waste.

[0031] As Figure 3 shown, the fluorinated liquid has good cooling performance, can quickly reduce the temperature of the hub bearing, and improve production efficiency. Reducing the temperature of the hub bearing can reduce the thermal impact on the subsequent conveying device, extend the service life of the equipment, and reduce the failure rate.

[0032] As Figure 3 shown, the bottom output end of the blanking chute 901 is connected to a non-contact conveying platform 904. A magnetic levitation conveying chute 905 is provided on the non-contact conveying platform 904. A first linear guiding portion 906 and a second linear guiding portion 907 are provided on the magnetic levitation conveying chute 905. Superconducting electromagnetic levitation components 908 based on magnetic levitation technology are provided at the bottom of the chute bodies of the first linear guiding portion 906 and the second linear guiding portion 907 of the magnetic levitation conveying chute 905. Among them, the superconducting electromagnetic levitation component 908 uses a superconducting electromagnet and requires an accurate control system to maintain the stability of the levitated body (hub bearing). The non-contact conveying is realized by using magnetic levitation technology, avoiding direct contact between the parts and the conveying device, and reducing wear and pollution.

[0033] As Figure 3 shown, in the first linear guiding portion 906 and the second linear guiding portion 907 of the magnetic levitation conveying chute 905, the magnetic field force generated by the superconducting electromagnetic levitation component 908 is used to further increase the levitation height and stability of the hub bearing. The key of the superconducting electromagnetic levitation component 908 lies in the superconducting electromagnet, which can achieve zero resistance at extremely low temperatures and generate a strong magnetic field. The first linear guiding portion 906 and the second linear guiding portion 907 are used to guide the hub bearing to move along a predetermined path to ensure the accuracy and stability of the conveying. The entire system requires an accurate 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 hub bearing.

[0034] As Figure 3As shown, direct contact between the hub bearing and the conveying device is avoided, significantly reducing wear and scratches, and improving the quality and service life of the parts.

[0035] As Figure 3 shown, on both sides of the trough body of the first linear guiding part 906 and the second linear guiding part 907 of the magnetic levitation conveying trough 905, air floating assemblies 14 based on a high-pressure air source for spray drying are provided to achieve non-contact conveying of the hub bearing. Specifically, the air floating assembly 14 includes air holes 1401 provided on both sides of the trough body of the first linear guiding part 906 and the second linear guiding part 907 of the magnetic levitation conveying trough 905. The high-pressure air jet assembly 1402 sprays high-pressure gas onto the surface of the hub bearing through the air holes 1401, forming an air film between the hub bearing and the side surface of the magnetic levitation conveying trough 905. This air film is like an air cushion, keeping the hub bearing in a non-contact state with the side wall of the trough body, thereby achieving frictionless conveying. The air floating assembly 14 works in cooperation with the superconducting electromagnetic levitation assembly 908 at the bottom of the magnetic levitation conveying trough 905. The magnetic levitation assembly mainly provides an upward supporting force to suspend the hub bearing; the air floating assembly 14 mainly provides a lateral guiding force and stability to prevent the hub bearing from contacting the side wall.

[0036] As Figure 3 shown, on the basis of magnetic levitation, a side air floating assembly 14 is added to achieve full-range non-contact between the hub bearing and the conveying trough. This maximally reduces the risks of wear, scratches, and contamination, and is especially suitable for hub bearings with extremely high requirements for surface quality. The air floating assembly 14 can effectively suppress the lateral sway of the hub bearing during conveying, improving the stability of conveying. Especially in the case of high-speed conveying or the presence of external interference, the role of air floating guidance is more obvious.

[0037] As Figure 3As shown, the air holes 1401 are arranged in rows on the double sides of the first linear guiding part 906 and the second linear guiding part 907, and the air outlet of the air hole 1401 is in a duckbill shape. The duckbill shape helps to converge and accelerate the air flow, improving the thrust efficiency. The hub bearing forms a guiding path inside the magnetic levitation conveying groove 905. The air holes 1401 are arranged obliquely towards the guiding path of the hub bearing. The dry high-pressure air source is ejected through the duckbill-shaped air holes 1401 to generate a directional thrust. The air holes 1401 are arranged obliquely towards the guiding path of the hub bearing, so that the ejected gas thrust is not only radial but also has an axial component. This axial component directly pushes the hub bearing to move along the guiding path. Two opposite air holes 1401 generate inclined thrusts on the two opposite inner sides of the hub bearing. The radial components of these two thrusts cancel each other out partly, but are still sufficient to form a thin air film between the hub bearing and the inner wall of the magnetic levitation conveying groove 905. The function of this air film is to prevent the hub bearing from directly contacting the groove wall, thereby reducing friction, wear and pollution. Through the pressure distribution of the air film, certain damping and stability are provided to prevent the hub bearing from vibrating violently or deviating from the guiding path during movement.

[0038] As Figure 3 and Figure 4 shown, the air floating assembly 14 further includes a high-pressure air jetting assembly 1402. One output end of the high-pressure air jetting assembly 1402 is connected with a first air supply pipe 1403. The output end of the first air supply pipe 1403 is connected with a main pipe 1404. A plurality of branch pipes 1405 are arranged on the main pipe 1404. The output end of the branch pipe 1405 is communicated with an air jet head. The air jet head is located inside the air hole 1401. Through the high-pressure air jetting assembly 1402, a stable and high-pressure air source is provided to ensure sufficient gas supply for each air jet head. The first air supply pipe 1403, the main pipe 1404 and the branch pipes 1405 construct a gas distribution network. The design of the air jet head can accelerate the gas inside the air hole 1401, making it eject at a higher speed, thereby generating a greater thrust. The shape of the air hole 1401 and the position of the air jet head can precisely control the direction of the air flow, making it eject at a predetermined angle, so as to achieve the best pushing and levitation effects.

[0039] As Figure 4As shown, the magnetic levitation conveying trough 905 is provided with an arc-shaped corner portion 909. The arc-shaped corner portion 909 is used to connect the first linear guiding portion 906 and the second linear guiding portion 907. The arc-shaped design provides a continuous turning path, avoiding the impact and material accumulation caused by sharp turns. The magnetic levitation conveying trough 905 requires a smooth transition of materials, and the arc-shaped corner is precisely for providing this smooth transition track. A buffer pad 15 is provided on the inner surface of the arc-shaped corner portion 909. The main function of the buffer pad 15 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 a straight line direction, thus hitting the inner side of the corner. The buffer pad 15 can slow down the impact and prevent the material from directly colliding with the hard trough wall. Flexible material scraping plates 16 are evenly provided on the inner surface of the buffer pad 15. The scraping plates 16 are arranged obliquely towards the guiding path. The inclination angle of the scraping plates 16 determines the guiding effect on the material. When the hub bearing hits the scraping plate 16, the inclined angle will guide the material towards the center of the guiding path, thus assisting it to complete the turning. Moreover, the flexible material scraping plates 16 can effectively scrape off the residual oil stains and metal debris adhering to the radial surface of the hub bearing, reducing the entry of sundries into the subsequent conveying device and ensuring the smoothness of the hub bearing conveying.

[0040] As Figure 4 shown, the synergistic effect of the arc-shaped corner portion 909, the buffer pad 15, and the inclined scraping plates 16 ensures that the material can complete the turning smoothly, avoiding problems such as jamming, tilting, or tumbling.

[0041] As Figure 4 shown, a upper stop portion 17 is provided at the top of the scraping plate 16. An L-shaped limiting groove is formed inside the upper stop portion 17 of the scraping plate 16. The upper stop portion 17 contacts the hub bearing and uses the L-shaped limiting groove to strictly limit the movement track of the hub bearing during the transfer process, avoiding unexpected upward deviation during its rotation and movement. Avoiding upward deviation ensures that the scraping plate 16 always acts on the surface of the hub bearing at a set angle and pressure. This can ensure the depth and uniformity of the scraping and cleaning, avoiding the situation of incomplete scraping or excessive scratching of the surface. The stable position of the hub bearing and the action of the scraping plate 16 can improve the scraping efficiency. Avoiding the need for repeated scraping due to the jumping or displacement of the hub bearing reduces the working hours.

[0042] As Figure 4 shown, further, another output end of the high-pressure air jet assembly 1402 is connected with a second air supply pipe 18. The output end of the second air supply pipe 18 is connected with an arc-shaped pipe 19. The arc-shaped pipe 19 is fixed on the magnetic levitation conveying trough 905 through a pipe support frame, and the arc-shaped pipe 19 is located directly above the arc-shaped corner portion 909. A plurality of branch pipes 20 are provided at the bottom of the arc-shaped pipe 19. The output ends of the branch pipes 20 communicate with spray nozzles. The spray nozzles face the inside of the limiting groove and are used to remove the waste scraped inside the limiting groove.

[0043] As Figure 4 shown, the high-pressure jet assembly 1402 generates high-speed airflows through the nozzles on the first air supply pipe 1403, the arc-shaped pipe 19, and the branch pipe 20. The design of the arc-shaped pipe 19 can evenly distribute the airflows to various positions of the arc-shaped corner part 909, ensuring the coverage range of waste removal. The nozzles face towards the inside of the limit groove and can directly act on the scraped waste to provide an initial driving force. The high-speed airflows blow the waste out of the inside of the limit groove. Under the push of the airflows, the waste obtains a downward momentum. At the same time, under the action of gravity, the waste will accelerate downward. The combination of these two forces makes it easier to remove the waste. The arc-shaped sewage discharge port is arranged at the bottom of the arc-shaped corner part 909 of the magnetic levitation conveying trough 905, and its shape matches the radian of the corner part. It can collect the waste blown down by the airflows to the maximum extent, avoiding the accumulation or diffusion of waste in the conveying trough. The arc-shaped design can guide the smooth flow of the airflows, reduce the turbulence and resistance generated by the airflows at the corner, and improve the removal efficiency of the airflows. The bottom of the arc-shaped sewage discharge port is connected to the sewage discharge pipe, which can conveniently discharge the collected waste out of the conveying system to realize the centralized treatment of the waste.

[0044] As Figure 4 shown, the high-pressure airflows in cooperation with the arc-shaped sewage discharge port can quickly and effectively remove the waste in the limit groove, preventing the waste from accumulating at the corner and affecting the conveying efficiency and product quality.

[0045] As Figure 4 shown, a disc groove 21 is provided on the inner ring part of the arc-shaped corner part 909 of the magnetic levitation conveying trough 905. The disc groove 21 is coaxially arranged with the arc-shaped corner part 909, and a material guiding part is formed at the tangential connection between the disc groove 21 and the magnetic levitation conveying trough 905. A rotatable feeding disc 22 is arranged inside the disc groove 21, and arc-shaped and concave material clamping parts 23 are evenly arranged on the outer ring surface of the feeding disc 22.

[0046] As Figure 4 shown, when the hub bearing reaches the arc-shaped corner from the first linear guiding part 906, a smooth transition is achieved through the material guiding part between the magnetic levitation conveying trough 905 and the disc groove 21. The tangential design of the material guiding part avoids the collision or jamming of the bearing when entering the disc groove 21. The feeding disc 22 inside the disc groove 21 rotates, and the material clamping parts 23 (arc-shaped and concave) on its outer ring can precisely "capture" and fix the floating hub bearing. As the feeding disc 22 rotates, the hub bearing is carried by the material clamping parts 23 and moves along the circumferential direction. When the material clamping parts 23 carry the hub bearing and rotate to a position aligned with the second linear guiding part 907, the hub bearing smoothly transitions to the second section of the linear conveying line to continue the subsequent processes.

[0047] As Figure 4As shown, by adjusting the rotation speed of the feeding tray 22 and the size of the material clamping part 23, the conveying requirements of hub bearings of different sizes and weights can be met.

[0048] As Figure 4 shown, further, the material clamping parts 23 are distributed at equal angles around the central axis of the feeding tray 22, and a number of buffer air bags 24 are provided on the arc surface of the material clamping part 23 of the feeding tray 22. When the hub bearing falls into the material clamping part 23, the buffer air bags 24 can play a buffering role and absorb the impact force. This can avoid the hard collision between the hub bearing and the material clamping part 23, reduce vibration and noise. The buffer air bags 24 can also help the hub bearing to be better positioned in the material clamping part 23 to a certain extent. After being compressed, the air bags will generate a certain reaction force, making the hub bearing more stably fixed in the material clamping part 23.

[0049] As Figure 4 shown, the use of the buffer air bags 24 makes the conveying process more gentle, further reducing the risk of damage to the hub bearing, which is very important especially for bearings with high surface quality requirements.

[0051] The above are all preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
