Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hub bearing processing equipment, in particular to a conveying device and a hub bearing inner ring cross-equipment conveying method. BACKGROUND

[0002] At present, the production process of hub bearings mainly includes forging or stamping forming of raw materials, heat treatment to improve hardness and wear resistance, precision machining to ensure dimensional accuracy and surface finish, polishing and cleaning of the raceway, rust prevention and passivation treatment, manufacturing of the retainer (stamping or plastic molding), assembly of the inner and outer rings and rolling elements, filling and sealing of lubricating grease, and finally strict performance testing and quality inspection to ensure that the products meet the standards.

[0003] At present, polishing and cleaning and rust prevention and passivation treatment of bearing hubs are usually realized by using polishing and cleaning machines and rust prevention and passivation devices. However, the metal surface after polishing and cleaning is highly active and is prone to electrochemical corrosion, such as pitting, in a humid or salt-containing environment. Therefore, when transferring hub bearings between the polishing and cleaning machine and the rust prevention and passivation device, the subsequent installation or operation may be exacerbated by the adsorption of dust, hand sweat and other pollutants.

[0004] The existing hub bearing inner ring conveying method mostly uses a combination of a conveyor belt system and a material guide groove. However, this method has the following disadvantages: the hub bearings slide in the material guide groove, and it is difficult to effectively control the sliding speed, which easily leads to mutual impact and thus damages the product quality.

[0022] Preferably, a hub bearing inner ring cross-device conveying method based on the conveying device, the steps of conveying the hub bearing include:

[0023] S1: the polished and cleaned hub bearing is placed into the inclined slot body through the clamping assembly, the axial end face of the hub bearing abuts against the bottom plate, and the hub bearing slides in the inside of the slot body;

[0024] S2: the driving motor synchronously drives the rotating shaft to drive the eccentric rod to move in a circle, the roller at the end of the eccentric rod abuts against the outer surface of the flexible peristaltic sleeve, simulates the "throat swallowing" action, makes the peristaltic sleeve peristaltic intermittently, generates friction, and slows down the sliding speed of the hub bearing;

[0028] In summary, the present application has the following beneficial effects:

[0029] 1. By adjusting the power of the drive motor, the rotation rate of the rotating shaft can be adjusted, so that the discharge speed of the wheel hub bearing can be accurately controlled, avoiding the impact caused by too fast speed. By controlling the discharge speed, the distance between adjacent wheel hub bearings can be widened, reducing or avoiding the impact of them during sliding. Reducing impact and wear helps to maintain the polishing quality of the wheel hub bearing and ensures the effectiveness of the subsequent rust-proof passivation treatment. Although the sliding speed of individual wheel hub bearings is reduced, the more stable and controllable transfer can reduce downtime caused by impact, jamming, etc., and improve overall transfer efficiency. In short, this peristaltic assembly simulates the action of swallowing by the throat to achieve buffering, deceleration and separation of the wheel hub bearing, thereby improving the transfer quality and efficiency;

[0030] 2. The interlayer divides the built-in cavity into independent areas, achieving precise control of pressure in different areas. The first sealed cavity encloses the alloy support strip, which is directly subjected to the force of the roller and transmits the force through the alloy strip. Imitate the "muscles of the throat": the whole device aims to mimic the peristalsis of the throat muscles through the above structure and movement. It will achieve the guiding effect of the wheel hub bearing.

[0031] 3. By imitating "throat saliva", the role of "throat saliva" is to lubricate the esophagus, making food easier to pass through and reducing friction and resistance. Here, by imitating this principle, lubricating oil is released on the arc contact surface of the flexible peristaltic sleeve, the purpose is to reduce the friction between the flexible peristaltic sleeve and the wheel hub bearing. Through lubrication, dry friction between the peristaltic sleeve and the wheel hub bearing can be effectively reduced or even eliminated. Dry friction will cause increased resistance, resulting in jamming. The addition of lubricating oil will convert dry friction to liquid friction, greatly reducing the friction coefficient and making the movement smoother.

[0032] 4. "Peristalsis" and "lubrication" are synchronized: the "peristalsis" action of the flexible peristaltic sleeve is synchronized with the release of "lubricating oil" from the drop point tube. This means that the flexible peristaltic sleeve arc-shaped contact surface is always lubricated while the flexible peristaltic sleeve is moving, avoiding dry friction.

[0033] 5. The vibration motor drives the vibration plate to produce intermittent and regular vibrations. The regular vibrations fine-tune the position of the hub bearing, avoiding the hub bearing from hitting the inner surface of the second side plate when turning in the arc-shaped guide groove, for reducing wear and tear, making them more evenly distributed on the guide path, improving load capacity and life.

[0043] As shown in the figure, further, the output slot 3 comprises a first bottom plate 301 with an included angle of 15° with the horizontal plane and two first side plates 302 fixed on the upper surface of the first bottom plate 301, and a downwardly inclined slot body 303 is formed between the two first side plates 302 and the first bottom plate 301, the polished and cleaned hub bearing after polishing and cleaning by the polishing and cleaning machine 1 is placed in the slot body 303 inside the clamping assembly, at this time the axial end face of the hub bearing is attached to the upper surface of the first bottom plate 301, and under the action of the inclination of the slot body 303, the hub bearing slides downward along the internal space of the slot body 303. Figure 2 As shown in the figure, further, the output slot 3 comprises a first bottom plate 301 with an included angle of 15° with the horizontal plane and two first side plates 302 fixed on the upper surface of the first bottom plate 301, and a downwardly inclined slot body 303 is formed between the two first side plates 302 and the first bottom plate 301, the polished and cleaned hub bearing after polishing and cleaning by the polishing and cleaning machine 1 is placed in the slot body 303 inside the clamping assembly, at this time the axial end face of the hub bearing is attached to the upper surface of the first bottom plate 301, and under the action of the inclination of the slot body 303, the hub bearing slides downward along the internal space of the slot body 303.

[0044] Figure 2 As shown in the figure, further, the output slot 3 comprises a first bottom plate 301 with an included angle of 15° with the horizontal plane and two first side plates 302 fixed on the upper surface of the first bottom plate 301, and a downwardly inclined slot body 303 is formed between the two first side plates 302 and the first bottom plate 301, the polished and cleaned hub bearing after polishing and cleaning by the polishing and cleaning machine 1 is placed in the slot body 303 inside the clamping assembly, at this time the axial end face of the hub bearing is attached to the upper surface of the first bottom plate 301, and under the action of the inclination of the slot body 303, the hub bearing slides downward along the internal space of the slot body 303.

[0045] As shown in the figure, further, the output slot 3 comprises a first bottom plate 301 with an included angle of 15° with the horizontal plane and two first side plates 302 fixed on the upper surface of the first bottom plate 301, and a downwardly inclined slot body 303 is formed between the two first side plates 302 and the first bottom plate 301, the polished and cleaned hub bearing after polishing and cleaning by the polishing and cleaning machine 1 is placed in the slot body 303 inside the clamping assembly, at this time the axial end face of the hub bearing is attached to the upper surface of the first bottom plate 301, and under the action of the inclination of the slot body 303, the hub bearing slides downward along the internal space of the slot body 303. Figure 2 Figure 3 ​​As shown, in particular, the peristaltic assembly 5 includes a base plate 501, wherein the base plate 501 is mounted on the first bottom plate 301, and a flexible peristaltic sleeve 502 is arranged on the base plate 501, the base plate 501 is used to fix the flexible peristaltic sleeve 502 and ensure the stability of the peristaltic movement of the flexible peristaltic sleeve 502. The material of the flexible peristaltic sleeve 502 is silica gel, and the flexible peristaltic sleeve 502 is a key component, and the silica gel material gives it good elastic deformation ability. Moreover, the inner surface of the flexible peristaltic sleeve 502 is provided with an arc-shaped contact surface in the shape of a simulated laryngeal tube, and this arc-shaped contact surface is the part that directly contacts the hub bearing. The arc-shaped design is more in line with the surface of the hub bearing, increasing the contact area and thus providing more uniform friction. The flexible silica gel material is relatively soft, which can reduce the wear on the surface of the hub bearing. The arc-shaped contact surface in the shape of a simulated laryngeal tube can also more evenly distribute pressure and avoid local stress concentration. Moreover, the thickness of the arc-shaped contact surface of the flexible peristaltic sleeve 502 is greater than that of other parts of the flexible peristaltic sleeve 502. By increasing the thickness of the contact surface, the wear resistance and strength of the flexible peristaltic sleeve 502 at the arc-shaped contact surface part are improved to withstand the pressure and friction of the hub bearing. At the same time, the thickness difference may also affect the deformation mode of the peristaltic sleeve, making it more likely to produce a swallowing-like action.

[0046] As shown in Figure 4 The peristaltic assembly 5 also includes a driving motor and a plurality of rotating shafts 503 that can rotate synchronously in the same direction. The driving motor is used to drive the plurality of rotating shafts 503, and a linkage member is arranged between the output end of the driving motor and the rotating shafts 503. In particular, the linkage member includes a belt pulley arranged at the bottom of the rotating shaft 503 and coaxially connected thereto. A plurality of belt pulleys are connected by a belt, and the output end of the driving motor is connected to the bottom center point of any belt pulley. The synchronous driving of the plurality of rotating shafts 503 by the driving motor causes the eccentric rod 504 arranged on the rotating shaft 503 to move in a circular motion. One end of the eccentric rod 504 is provided with a roller 505, which is attached to the outer surface of the flexible peristaltic sleeve 502. This causes the flexible peristaltic sleeve 502 to move intermittently, so that the flexible peristaltic sleeve 502 can generate friction on the hub bearing to slow down its sliding speed. By adjusting the power of the driving motor and the rotation rate of the rotating shaft 503, the discharge speed of the hub bearing can be accurately controlled to avoid impact caused by excessive speed. By controlling the discharge speed, the distance between adjacent hub bearings can be increased to reduce or avoid collisions between them during sliding. Reducing impact and wear helps to maintain the polishing quality of the hub bearing and ensures the effectiveness of subsequent rust-proof passivation treatment. Although the sliding speed of individual hub bearings is reduced, the more stable and controllable transfer can reduce downtime caused by problems such as impact and jamming, thereby improving overall transfer efficiency.

[0047] In short, this peristaltic assembly 5 simulates the action of swallowing the throat to achieve buffering, deceleration, and separation of the hub bearing, thereby improving the transfer quality and efficiency.

[0048] As Figure 4 shown, the flexible peristaltic sleeve 502 forms an internal cavity with the base plate 501, and a sandwich layer 506 is arranged in the internal cavity of the flexible peristaltic sleeve 502. The sandwich layer 506 is made of the same material as the flexible peristaltic sleeve 502, and both are made of silicone. The sandwich layer 506 divides the internal cavity of the flexible peristaltic sleeve 502 into a first sealed cavity and a second sealed cavity, which are independent of each other. The silicone sandwich layer 506 divides the internal cavity into independent first and second sealed cavities; this allows independent control of different areas and more precise simulation of the movement of the "laryngeal muscles". The first sealed cavity is close to the roller 505, and the inside of the first sealed cavity is wrapped with a number of alloy support strips 507. The alloy support strips 507 are long strip structures perpendicular to the base plate 501. The alloy support strips 507 and the sandwich layer 506 are adhesively arranged. When the roller 505 swings, the alloy support strips 507 are subjected to pressure, providing support for the sandwich layer 506. This support can be understood as the role of "skeleton", which allows the flexible structure to maintain a specific shape and direction when subjected to force, rather than deforming randomly. The intermittent swing of the roller 505 is the driving mechanism. By applying pressure to the alloy support strips 507, directional pressure is applied to the flexible peristaltic sleeve 502. This simulates the pushing force generated when the laryngeal muscles contract.

[0049] As Figure 4 shown, the roller 505 provides power, and the alloy support strips 507 convert the power into directional pressure, together realizing precise peristaltic movement.

[0050] As Figure 4 shown, the muscles of the larynx push food or liquid downward by rhythmic contraction and relaxation, which is peristalsis. The device produces similar peristaltic movement by controlling the pressure changes in the first and second sealed cavities. The alloy support strips 507 play a crucial role. When the shaft 503 swings and exerts pressure on the alloy support strips 507 in the sandwich layer 506, the support strips disperse and transmit the pressure directionally to the flexible peristaltic sleeve 502. This directional pressure simulates the directionality when the laryngeal muscles contract.

[0051] As Figure 4 shown, the sandwich layer 506 divides the internal cavity into independent areas, allowing precise control of pressure in different areas. The first sealed cavity wraps the alloy support strips 507, which are directly subjected to the force of the roller 505 and transmit the force through the alloy strips. The device simulates the "muscles of the larynx": the goal of the entire device is to mimic the peristalsis of the laryngeal muscles through the above structure and movement. The hub bearing will guide the movement.

[0052] As Figure 4As shown, the interior of the second sealing cavity is equipped with a lubrication release component 6 for releasing lubricating oil onto the arc-shaped contact surface of the flexible peristaltic sleeve 502. This lubrication release component 6 mimics the function of saliva in the throat, which lubricates the esophagus, making it easier for food to pass through and reducing friction and resistance. Here, lubricating oil is released onto the arc-shaped contact surface of the flexible peristaltic sleeve 502 to reduce the friction between the flexible peristaltic sleeve 502 and the hub bearing. Lubrication effectively reduces or even eliminates dry friction between the peristaltic sleeve and the hub bearing surface. Dry friction leads to increased resistance, resulting in jamming. The addition of lubricating oil transforms dry friction into liquid friction, significantly reducing the coefficient of friction and making the movement smoother.

[0053] like Figure 4 As shown, the function of the lubricating oil release component 6 is to evenly distribute the lubricating oil on the surface of the wheel hub bearing. A uniform lubricating film provides a more effective friction reduction effect and avoids wear or oxidation caused by insufficient local lubrication. The surface of the wheel hub bearing is very clean after polishing and cleaning, but it is also more susceptible to oxidation. The lubricating oil can form a protective film that isolates oxygen and moisture, thereby effectively preventing oxidation and rust on the surface of the wheel hub bearing.

[0054] like Figure 4 As shown, in summary, this design improves equipment performance and lifespan by reducing friction through lubrication, preventing jamming, and providing oxidation protection.

[0055] like Figure 4 As shown, the liquid release assembly 6 includes a main hose 601 parallel to the substrate 501. One end of the main hose 601 is closed, and the other end of the main hose 601 is connected to a lubricating oil supply assembly for supplying lubricating oil. The main hose 601 is serpentine inside the second sealed cavity. Several branch hoses 602 are provided on the upper surface of the main hose 601. Several drip tubes 603 are connected to the branch hoses 602. The drip tubes 603 are evenly spaced along the longitudinal direction of the branch hoses 602. One end of the drip tube 603 is connected to the branch hose 602, and the other end of the drip tube 603 extends through and extends to the arc-shaped contact surface of the flexible peristaltic sleeve 502.

[0056] like Figure 4As shown, the total hose 601 is in a serpentine shape, increasing the flow path of the lubricating oil and facilitating the stability of the oil pressure. The total hose 601 is pressurized by the alloy support strip 507, forming a positive pressure inside the total hose 601, ensuring that the lubricating oil can overcome the resistance and flow smoothly from the total hose 601 to the branch hose 602. The branch hose 602 branches from the total hose 601, equivalent to multiple branches, dispersing the lubricating oil in the total hose 601 and providing a basis for uniform oil dripping. The evenly spaced drip point pipes 603 are the final link in the release of lubricating oil. The outlets of the drip point pipes 603 directly face the arc contact surface of the flexible peristaltic sleeve 502, allowing precise dripping of lubricating oil to the parts that need to be lubricated.

[0057] As shown, Figure 4 The "peristalsis" is synchronized with the "lubrication": the "peristalsis" action of the flexible peristaltic sleeve 502 is synchronized with the release of "lubricating oil" by the drip point pipe 603. This means that while the flexible peristaltic sleeve 502 is moving, the arc contact surface of the flexible peristaltic sleeve 502 is always lubricated, avoiding dry friction.

[0058] As shown, Figure 4 Through the design of the serpentine total hose 601, branch hose 602, and evenly spaced drip point pipes 603, the lubricating oil can be uniformly distributed on the entire arc contact surface of the flexible peristaltic sleeve 502. Compared with direct spraying or soaking, this method is more precise and controllable, avoiding waste of lubricating oil and local lubrication deficiency.

[0059] As shown, Figure 4 Specifically, the end of the drip point pipe 603 away from the branch hose 602 is connected with a spherical hollow capsule 604, which communicates with the drip point pipe 603, and the spherical hollow capsule 604 is provided with a cross-shaped opening. The spherical hollow capsule 604 acts as a micro oil reservoir, which can store a small amount of lubricating oil. At the same time, the elastic deformation of the spherical hollow capsule 604 can act as a buffer to absorb the pressure fluctuations in the total hose 601, maintaining the stability of the outlet pressure of the drip point pipe 603. The cross-shaped opening forms four small release channels on the surface of the capsule. Under the action of pressure, the lubricating oil slowly and uniformly seeps out through the four channels. This design avoids the one-time large drop of lubricating oil, ensuring the continuity and uniformity of lubrication. Even if a small amount of impurities enters the drip point pipe 603, the structure of the spherical hollow capsule 604 and the cross-shaped opening can reduce the possibility of blockage. Impurities may be captured by the capsule or washed away through the cross-shaped opening.

[0060] Example 2, as Figure 5As shown, the output end of the output slot 3 is provided with an arc-shaped guide plate 7, and directly below the arc-shaped guide plate 7 is provided with a turning slot 8. The hub bearing output from the output slot 3 is guided by the arc-shaped guide plate 7 to the inside of the turning slot 8. Specifically, the turning slot 8 includes a second bottom plate 801, and the upper surface of the second bottom plate 801 is provided with two second side plates 802, and an arc-shaped guide slot is formed between the two second side plates 802. The end of the guide slot and close to the arc-shaped guide plate 7 is provided with a retractable shovel plate 803. The shovel plate 803 is driven by an electric telescopic rod, and under the action of the shovel plate 803, the sliding hub bearing is turned by 90°, so that the radial surface of the hub bearing rolls in the inside of the turning slot 8. Specifically, the hub bearing coming out of the output slot 3 will slide down at a certain speed due to inertia or gravity. When the hub bearing falls into the vicinity of the shovel plate 803, the shovel plate 803 is extended under the drive of the electric telescopic rod to block the continuous sliding of the hub bearing. Because the shovel plate 803 has a certain angle or arc, the hub bearing will be forced to tilt upward or laterally while being blocked. The design of the shovel plate 803 makes the hub bearing no longer slide on the end surface, but the lateral radial surface contacts the inner wall of the turning slot 8, so as to realize the change of the rolling direction. The turned hub bearing can continue to roll in the new direction.

[0061] As shown in Figure 5 , the arc-shaped guide plate 7 functions to gently change the motion direction of the hub bearing, converting the original linear motion into motion along an arc. This process avoids direct impact of the hub bearing on the turning slot 8, reducing impact and possible damage. The turning slot 8 provides a clear motion path to constrain the hub bearing to roll along a specific arc. The second bottom plate 801 and the side plates form a groove to ensure that the hub bearing always remains on the predetermined track and does not deviate or tip over.

[0062] As shown in Figure 5 , this design realizes automatic adjustment of the attitude of the hub bearing without manual intervention. This is crucial on an automated production line, which can improve production efficiency and reduce labor costs.

[0063] As shown in Figure 5As shown, the inner part of the guide groove forms a guide path along the rolling direction of the hub bearing, and a plurality of flexible guide sleeves 804 are evenly arranged on the inner side wall of the two second side plates 802 along the guide path. The material of the flexible guide sleeve 804 is silica gel, and the inner cavity of the flexible guide sleeve 804 is provided with a vibrating plate. The vibrating plate is used to generate intermittent regular vibration, one end of the vibrating plate is occluded in the inner part of the flexible guide sleeve 804, and the other end of the vibrating plate is connected with the output end of the vibration motor 805. The guide groove defines a guide path in the rolling direction, and the flexible guide sleeve 804 provides additional flexible support and constraint. The flexible guide sleeve 804 made of silica gel has a certain buffering and damping effect. The vibration motor 805 drives the vibrating plate to generate intermittent regular vibration. The vibrating plate is located in the inner cavity of the flexible guide sleeve 804, so the vibration is transmitted to the guide sleeve and then to the rolling element.

[0064] As shown in Figure 5 , the regular vibration can fine-tune the position of the hub bearing to avoid the hub bearing from colliding with the inner surface of the second side plate 802 when turning in the arc-shaped guide groove, thereby reducing wear and making them more evenly distributed on the guide path, improving load capacity and service life.

[0065] As shown in Figure 5 , the angle between the vibrating plate and the second side plate 802 is 15-20°. After testing, it is found that this angle can more effectively transmit vibration energy to the hub bearing to achieve the purposes of vibration reduction, lubrication improvement, or prevention of jamming.

[0066] Embodiment 3, as shown in Figure 6 , the rust-proof passivation device 2 is provided with a guide rail 9, the inner part of the guide rail 9 is provided with a discharge hole, the discharge hole and the input end of the rust-proof passivation device 2 are provided with a downward inclined input slot 4, the guide end of the guide groove faces the guide rail 9, the guide groove rises and falls in the inner part of the guide rail 9, and the guide groove and the guide rail 9 are provided with a linear motor 10 for driving the guide groove to rise and fall. When the guide groove moves upward by the linear motor 10 until the output end of the guide groove coincides with the discharge hole, the hub bearing in the guide groove will be guided to the inside of the rust-proof passivation device 2 along the input slot 4. This step-by-step feeding method can avoid the problems of blockage or inaccurate positioning caused by one-time feeding.

[0067] Embodiment 4, a hub bearing inner ring cross-device conveying method based on the conveying device, the steps of conveying the hub bearing include:

[0068] S1: The hub bearing polished and cleaned by the polishing cleaning machine 1 is placed in the clamping assembly inside the hub bearing, at this time the axial end face of the hub bearing is attached to the upper surface of the first bottom plate 301, and under the action of the inclination of the groove 303, the hub bearing slides downward along the internal space of the groove 303.

[0069] S2: By turning on the power supply of the driving motor, the synchronous driving of the plurality of rotating shafts 503 is realized, so that the eccentric rod 504 provided on the rotating shaft 503 is in circular motion, one end of the eccentric rod 504 is provided with a roller 505, the roller 505 is attached to the outer surface of the flexible peristaltic sleeve 502, and by simulating the action of "throat swallowing", the flexible peristaltic sleeve 502 is intermittently peristaltic, so that the flexible peristaltic sleeve 502 can generate friction force on the hub bearing, and slow down the sliding speed.

[0070] S3: By the pressure of the roller 505, a positive pressure is formed inside the total hose 601, so that the lubricating oil can overcome the resistance and smoothly flow from the total hose 601 to the branch hose 602; the branch hose 602 is branched from the total hose 601, which is equivalent to multiple branches, and disperses the lubricating oil in the total hose 601 to provide a basis for uniform oil dripping; by imitating "throat saliva", the flexible peristaltic sleeve 502 is moved at the same time, and the flexible peristaltic sleeve 502 arc-shaped contact surface can always be lubricated to avoid dry friction.

[0071] S4: The hub bearing coming out of the output groove 3 will slide down at a certain speed due to inertia or gravity. When the hub bearing falls into the guide groove and is close to the shovel plate 803 through the arc-shaped guide plate 7, the shovel plate 803 is driven to extend by the electric telescopic rod, blocking the continuous sliding of the hub bearing. Since the shovel plate 803 has a certain angle or arc, the sliding hub bearing is turned 90°, so that the radial surface of the hub bearing rolls in the inside of the turning groove 8.

[0072] S5: When a certain number of hub bearings are arranged in the guide groove, the guide groove moves upward by the linear motor 10 until the output end of the guide groove coincides with the discharge hole, at this time the hub bearings in the guide groove will be guided to the inside of the rust-proof passivation device 2 along the input groove 4.

[0073] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
