Description

Technical Field

[0001] The present invention relates to the technical field of hub processing equipment, and in particular, to a component sorting device and a hub bearing assembly line. Background Art

[0002] Hub bearings are key components in automobiles and other transportation tools. They are located between the wheels and the vehicle body, responsible for supporting the wheels and allowing them to rotate freely. The main function of hub bearings is to bear the loads and pressures generated during vehicle driving, ensuring the stability and safety of vehicle driving.

[0003] Hub bearings mainly consist of several components. The most core components are the inner ring bearing, outer ring bearing, and bearing flange. They are respectively embedded in the wheel and the vehicle body to achieve load bearing. In addition, rolling elements roll between the inner and outer rings to reduce the heat generated by friction. Another important component is the sealing ring, which prevents dust and moisture from entering the bearing interior, thereby protecting the lubrication effect of the hub bearing and extending its service life. Finally, grease or oil is a necessity to ensure the smooth operation of the hub bearing. It can effectively reduce friction and improve the overall performance.

[0004] Currently, in the production line of hub bearings, it is necessary to assemble the most core components of the hub bearings, ensuring the precise docking and perfect combination of each component. First, technical workers will check the integrity of the inner and outer rings to ensure that they have no defects. Then, an appropriate amount of grease is applied to the inner ring and rolling elements to reduce friction and improve operating efficiency.

[0005] However, in the above process, the manual method has certain limitations. Not only is the efficiency low, but it is also difficult for the same assembly line to synchronously sort the inner ring bearings, outer ring bearings, and bearing flanges, greatly reducing the assembly efficiency.

Detailed implementation manners

[0022] 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 implementation manners are only used to further illustrate the present application and cannot be understood as a limitation on the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0023] Embodiment 1. The present invention discloses a part sorting device for sorting inner ring bearings, outer ring bearings, and bearing flanges, as Figure 1As shown in the figure, it includes a frame body 1. A tabletop 2 is provided on the frame body 1. A support column 3 is fixedly installed on the tabletop 2. A cross plate 4 is fixedly installed at the top of the support column 3. Three detection components 5 for detecting the inner dimensions of the inner ring bearing, outer ring bearing, and bearing flange are fixedly installed on the cross plate 4.

[0024] As Figure 1 shown in the figure, a first conveyor belt 6 and a first sorting conveyor belt 7 for driving the inner ring bearing are provided on the tabletop 2. A detection component 5 is located between the output end of the first conveyor belt 6 and the input end of the first sorting conveyor belt 7. A first clamping and transfer component 8 is arranged on the tabletop 2. The first clamping and transfer component 8 is used to clamp and transfer the inner ring bearing on the first conveyor belt 6 into a detection component 5. After being detected by the detection component 5, it is transferred onto the first sorting conveyor belt 7, and an inner ring bearing sorting path is formed on the first sorting conveyor belt 7.

[0025] As Figure 1 and Figure 2 shown in the figure, specifically, the first clamping and transfer component 8 includes a vertical frame 81. A cross frame 82 is fixedly installed at the top of the vertical frame 81. A driving motor and a sliding rod 83 are fixedly installed on the cross frame 82. The output end of the driving motor is connected to a lead screw. A slidable sliding base 85 is provided on the sliding rod 83. The middle part of the lead screw passes through the inside of the sliding base 85. By driving the motor, the lead screw is driven to rotate, and the sliding base 85 is driven to move back and forth horizontally along the sliding rod 83.

[0026] As Figure 1 and Figure 2 shown in the figure, a hydraulic rod 86 is provided inside the sliding base 85. The bottom output end of the hydraulic rod 86 is connected to a connecting block 87. A fixed disk 84 is fixedly installed at the bottom of the connecting block 87. A first clamping tool 88 is provided at the bottom of the fixed disk 84. By the hydraulic rod 86, the connecting block 87 is pushed downward, causing the fixed disk 84 to have a longitudinal displacement, and the first clamping tool 88 is pushed near the inner ring bearing.

[0027] As Figure 1 and Figure 2 shown in the figure, generally speaking, the driving motor provides power through the lead screw. The rotation of the lead screw causes the sliding base 85 to move horizontally along the sliding rod 83. This horizontal movement enables the clamping device to be accurately positioned within the set route. The hydraulic rod 86 inside the sliding base 85 is controlled by a hydraulic system. The connecting block 87 at its bottom end is connected to the fixed disk 84. When the hydraulic rod 86 pushes the connecting block 87 downward, the fixed disk 84 moves downward accordingly, and the first clamping tool 88 is pushed near the inner ring bearing.

[0028] As Figure 2 and Figure 3As shown, when the first gripper 88 contacts the inner ring bearing, the first gripper 88 includes an upper base 881 and a lower base 882. The upper base 881 and the lower base 882 are closed, and are fixedly connected by bolts provided between the upper base 881 and the lower base 882. A hydraulic channel 883 is provided inside the lower base 882. The input end of the hydraulic channel 883 is connected to an external hydraulic device through a connecting pipe, and four piston pipes are connected near the output end of the hydraulic channel 883. A piston rod is slidably provided inside the piston pipe. Four chutes are equiangularly provided on the lower surface of the lower base 882. The piston rod is slidably arranged towards the inside of the chute, and is fixedly connected to a slider 884 provided in the chute. An L-shaped clamping rod 885 is provided at the bottom of the slider 884.

[0029] As Figure 3 shown, the external hydraulic device transfers hydraulic oil or liquid to the hydraulic channel 883 inside the lower base 882 through the connecting pipe to form positive pressure; the pressure of the hydraulic channel 883 causes the piston rods inside the four piston pipes to move outwards. The piston rod is connected to the slider 884, and the slider 884 slides in the chute, pushing the clamping rod 885 towards the inner ring bearing; when the L-shaped clamping rod 885 contacts the inner ring bearing, continue to apply pressure to push the clamping rod 885 towards the inner ring to complete the clamping process and achieve firm fixation of the bearing. After clamping the inner ring bearing, the sliding base 85 transfers the bearing to a detection component 5 through horizontal movement.

[0030] As Figure 3 and Figure 4 shown, further, a right-angled bayonet 886 is formed on the outer surface of the clamping rod 885. An embedding groove 887 is provided on the transverse part of the right-angled bayonet 886 of the clamping rod 885. A pneumatic bladder 888 is provided inside the embedding groove 887. The pneumatic bladder 888 is made of an elastic material, and a magnetorheological fluid is filled inside the pneumatic bladder 888. The pneumatic bladder 888 is provided with a liquid inlet, and the liquid inlet of the pneumatic bladder 888 is connected to an external liquid injection device.

[0031] As Figure 3 and Figure 4 shown, the pneumatic bladder 888 is made of a 3-8 mm thick neoprene, polyurethane or synthetic rubber elastic material, and a magnetorheological fluid is filled inside it. Under the action of an external magnetic field, the magnetorheological fluid can quickly change its viscosity and flow characteristics. Through the connected liquid injection device, the magnetorheological fluid is injected into the pneumatic bladder 888, increasing the internal volume of the pneumatic bladder 888, causing the pneumatic bladder 888 to expand, and then pushing the transverse part of the right-angled bayonet 886 of the clamping rod 885 to contact the shaft end surface of the inner ring bearing. Once the injected magnetorheological fluid changes its flow characteristics under the action of the magnetic field, the viscosity of the magnetorheological fluid can be instantly increased.

[0032] As Figure 3 andFigure 4 As shown, when the viscosity of the magnetorheological fluid increases, on the one hand, it can better adhere to and fill the gaps between the balls inside the inner ring bearing, and can well adapt to the uneven surface of the shaft end surface of the inner ring bearing, thereby improving the connection stability between the transverse part of the right-angle bayonet 886 of the clamping rod 885 and the shaft end surface of the inner ring bearing. On the other hand, during the clamping process, the magnetorheological fluid can provide a certain floating effect, reducing the concentration of the clamping force in a local area, thereby reducing the wear on the inner ring bearing and the clamping device. Moreover, the controllability of the magnetorheological fluid enhances the clamping stability, and can maintain the clamping force on the workpiece under external vibration or interference, ensuring the safety and reliability of the operation.

[0033] As Figure 3 and Figure 4 shown, preferably, the outer surface of the pneumatic bladder 888 is provided with a wear-resistant layer, and the material of the wear-resistant layer is polyethylene. Polyethylene is a flexible material. The flexible wear-resistant layer can effectively reduce the wear between the pneumatic bladder 888 and the bearing by providing an additional buffer and protection layer, and extend the service life of the pneumatic bladder 888.

[0034] As Figure 3 and Figure 4 shown, further, the wear-resistant layer surface of the pneumatic bladder 888 is sprayed with lubricating oil. When the wear-resistant layer of the pneumatic bladder 888 contacts the balls inside the inner ring bearing, the lubricating oil can effectively reduce the damage caused by the wear-resistant layer of the pneumatic bladder 888 to the balls.

[0035] As Figure 3 and Figure 4 shown, on the longitudinal part of the right-angle bayonet 886 of the clamping rod 885, there are provided an installation groove 8810 and a plurality of annular bladders 889. The annular bladders 889 are bonded to the clamping rod 885. The air inlets of the plurality of annular bladders 889 are communicated with the air supply pipe 8811 inside the installation groove 8810, and the air inlet of the air supply pipe 8811 is connected to an external air extraction and inflation device.

[0036] As Figure 3 and Figure 4 shown, the air extraction and inflation device injects air into the inside of the annular bladder 889 through the air supply pipe 8811, so that the internal volume of the annular bladder 889 increases. When the annular bladder 889 contacts the inner ring surface of the inner ring bearing, an airtight cavity is formed between the expanded annular bladder 889 and the inner ring bearing, and a buffering effect is achieved, reducing the damage of the clamping rod 885 to the inner ring bearing. It adopts a bionic octopus tentacle design; by extracting the air in the annular bladder 889 through the air extraction and inflation device, at this time, the cross-sectional size of the annular bladder 889 shrinks, and the airtight cavity becomes larger, which is used to form a negative pressure inside the airtight cavity, playing the role of the octopus tentacle adsorbing the inner ring surface of the inner ring bearing.

[0037] AsFigure 3 and Figure 4 As shown in Figure 4 , when the air extraction and inflation device injects air into the annular bladder 889 through the air supply pipe 8811, the internal volume of the annular bladder 889 increases, causing it to expand. This expansion causes the annular bladder 889 to come into contact with the inner surface of the inner ring bearing, forming a sealed cavity. During the process of the bladder expanding and contacting the inner ring bearing, the sealed cavity formed can effectively absorb and disperse the force transmitted to the clamping rod 885, reducing the impact and damage of the clamping rod 885 on the inner ring bearing, thereby playing a buffering role.

[0038] As Figure 3 and Figure 4 shown, when the air extraction and inflation device extracts the air from the annular bladder 889, the cross-sectional dimension of the annular bladder 889 shrinks, and the sealed cavity increases accordingly, thereby forming a negative pressure. This negative pressure causes the annular bladder 889 to act like an octopus tentacle, generating an adsorption effect and enhancing stability through contact with the inner ring bearing.

[0039] As Figure 3 and Figure 4 shown, this design is inspired by octopus tentacles. The flexibility and strong adsorption ability of this biological structure make docking and grasping safer and more reliable. Through the buffering effect, the annular bladder 889 can effectively reduce the direct impact of the clamping rod 885 on the inner ring bearing, reduce wear and damage, and extend the service life of the components. Moreover, this design can adapt to inner ring bearings of different sizes and shapes. By adjusting the injection and extraction of air, the annular bladder 889 can flexibly respond to various working environments.

[0040] As Figure 3 and Figure 4 shown, by respectively arranging a pneumatic bladder 888 filled with magnetorheological fluid inside on the transverse part and the longitudinal part of the right-angle bayonet 886 of the clamping rod 885 and an annular bladder 889 based on the principle of imitating octopus tentacles, the pneumatic bladder 888 is combined with the magnetic levitation mechanism to achieve phased and regional clamping of "soft contact - hard fixation". It can adapt to inner ring bearings with different cross-sectional dimensions, and has many advantages such as reducing wear on the inner ring bearing and having a good clamping effect.

[0041] Embodiment 2. As Figure 1 shown, a second transmission belt 9 for driving the outer ring bearing and a second sorting conveyor belt 10 are provided on the table 2. Another detection component 5 is located between the output end of the second transmission belt 9 and the input end of the second sorting conveyor belt 10. A second clamping and transfer component 11 is arranged on the table 2. The second clamping and transfer component 11 is used to clamp and transfer the outer ring bearing on the second transmission belt 9 into another detection component 5. After being detected by another detection component 5, it is transferred onto the second sorting conveyor belt 10, and an outer ring bearing sorting path is formed on the second sorting conveyor belt 10.

[0042] As Figure 1 shown, the structure of the second clamping and transferring component 11 is the same as that of the first clamping and transferring component 8 in Embodiment 1. It can clamp and transfer the outer ring bearing, and during the clamping process of the outer ring bearing, it can adapt to outer ring bearings with different cross-sectional dimensions, and has many advantages such as reducing wear on the outer ring bearing and having a good clamping effect.

[0043] Embodiment 3, as Figure 1 shown, a third conveyor belt 12 and a third sorting conveyor belt 13 for driving the bearing flange are provided on the table 2. Another detection component 5 is located between the output end of the third conveyor belt 12 and the input end of the third sorting conveyor belt 13. A third clamping and transferring component 14 is arranged on the table 2. The third clamping and transferring component 14 is used to clamp and transfer the bearing flange on the third conveyor belt 12 into another detection component 5, and after being detected by another detection component 5, it is transferred onto the third sorting conveyor belt 13, and a sorting path for the bearing flange is formed on the third sorting conveyor belt 13.

[0044] As Figure 5 and Figure 6 shown, among them, the third clamping and transferring component 14 includes a second clamping tool 141. The difference between the third clamping and transferring component 14 and the first clamping and transferring component 8 lies only in the first clamping tool 88 and the second clamping tool 141. The second clamping tool 141 includes a concave block 1411. An electric push rod 1412 and two spur gears 1413 are arranged inside the concave block 1411. The output end of the electric push rod 1412 is connected with a rack 1414. The rack 1414 is located between the two spur gears 1413 and is meshed with each other. A connecting rotating shaft 1415 is arranged at the central position of the rack 1414. A clamping rod 1416 is arranged on the connecting rotating shaft 1415. A clamping block 1417 is arranged on the inner surface of the clamping rod 1416. An arc surface 1418 matching the outer ring of the bearing flange is arranged on the inner surface of the clamping block 1417.

[0045] As Figure 5 and Figure 6 shown, by pushing the rack 1414 with the electric push rod 1412, the linear motion generated by the rack 1414 causes the two spur gears 1413 to rotate in opposite directions, and drives the two clamping rods 1416 to move relatively. When the two clamping blocks 1417 approach each other, the arc surface 1418 on the clamping block 1417 will come into contact with the outer ring of the bearing flange to stably clamp the bearing flange.

[0046] As Figure 5 and Figure 6As shown, when the output end of the electric push rod 1412 pushes the rack 1414, the rack 1414 starts to move along its length direction; the linear movement of the rack 1414 drives the two meshing spur gears 1413 to rotate in opposite directions. Since the movement of the rack 1414 generates the rotation of the spur gears 1413; the rotation of the two spur gears 1413 in turn causes the clamping rod 1416 connecting them to move relatively. When the clamping rods 1416 approach, the clamping blocks 1417 on their inner surfaces also approach; during the approach of the clamping blocks 1417, the designed arc surface 1418 thereof is in close contact with the outer ring of the bearing flange, thus ensuring stable clamping of the flange. The design of the arc surface 1418 matching the outer ring of the bearing flange enables the clamping block 1417 to provide a larger contact area during clamping, increasing the stability of clamping and effectively preventing the flange from sliding during operation.

[0047] As Figure 5 and Figure 6 shown, several special-shaped bladder bags 1419 are provided on the arc surface 1418 of the clamping block 1417 and are longitudinally distributed along it. The special-shaped bladder bags 1419 are adhesively bonded to the clamping block 1417, and the special-shaped bladder bags 1419 are connected to another air extraction and inflation device outside. When inflating, the other air extraction and inflation device is opened, so that the special-shaped bladder bags 1419 are inflated and expanded, which can increase the contact area and stability between the clamping block 1417 and the bearing flange. During the expansion process of the clamping block 1417, a flexible clamping can be formed, enabling the contact surface of the clamping block 1417 to better adapt to the shape of the flange.

[0048] As Figure 5 and Figure 6 shown, the cross-section of the special-shaped bladder bag 1419 is a folded line structure. The folded line structure can generate more complex deformation modes when gas is filled and extracted. When gas is filled, the folded line part of the special-shaped bladder bag 1419 can flexibly unfold, rather than relying solely on a uniform circular outer shell, which can provide more contact surfaces. The folded line structure enables the bladder bag to better adapt to the shape of the object to be clamped during inflation, increasing the contact area and enhancing the clamping force.

[0049] As Figure 5 and Figure 6 shown, generally speaking, by integrating the three sorting paths of the inner ring bearing sorting path, the outer ring bearing sorting path, and the bearing flange sorting path onto the same table 2 and through an automatic control method, efficient sorting of the inner ring bearings, outer ring bearings, and bearing flanges is achieved.

[0050] Example 4, as Figure 7As shown, the detection component 5 includes a positioning base 51 fixed on the upper surface of the table 2 and a driving member 52 arranged on the cross plate 4, an outer sleeve 53 is fixedly installed on the upper surface of the positioning base 51, the driving member 52 is a cylinder, and the output end of the cylinder is connected to an internal pressure column 54, the central axis of the internal pressure column 54 and the outer sleeve 53 coincide with each other, the inner ring bearing, the outer ring bearing and the bearing flange are placed inside the outer sleeve 53 through the first clamping and transporting component 8, the second clamping and transporting component 11 and the third clamping and transporting component 14 respectively, and the relative displacement of the inner ring bearing, the outer ring bearing and the inner and outer rings of the bearing flange is measured by the clearance measurement feedback component arranged on the inner wall of the outer sleeve 53. Specifically, the clearance measurement feedback component is any one of a laser rangefinder or an infrared sensor. When the cylinder drives the internal pressure column 54 to move, the clearance measurement feedback component monitors the relative position changes of the inner and outer ring bearings in real time, and feeds back the data to the control system.

[0051] like Figure 7 As shown, a pressure sensor is provided at the bottom of the inner pressure column 54 for real-time detection of the pressure of the inner pressure column 54. When the inner pressure column 54 applies pressure to the inner ring bearing, the outer ring bearing and the bearing flange, the pressure sensor continuously monitors the applied pressure value and feeds back the data to the control system in real time. By comparing the real-time collected pressure data with the preset standard pressure value, the system can determine the pressure state of the inner ring bearing, the outer ring bearing and the bearing flange and the corresponding deformation; according to the mechanical properties of the material and the corresponding critical value, the system can analyze whether the deformation of the component after being pressed is within the allowable range.

[0052] like Figure 7 As shown, an annular placement groove 55 is provided on the outer surface of the internal pressure column 54 near the bottom, an ultrasonic oscillator and an electric telescopic rod are provided inside the annular placement groove 55, and a fan-shaped scraper 56 is connected to the output end of the electric telescopic rod. First, the ultrasonic oscillator can generate high-frequency sound waves, which can propagate in the liquid and generate tiny bubbles. When these bubbles come into contact with dirt or oil, they will collapse instantly with extremely high energy, and the generated shock waves can effectively loosen and peel off the dirt attached to the inner wall of the outer sleeve 53.

[0053] like Figure 7 As shown, the electric telescopic rod is extended and retracted according to the control signal, driving the fan-shaped scraper 56 to extend outward and contact the inner wall of the outer sleeve 53. The fan-shaped scraper 56 further cleans the oil dirt loosened by the ultrasonic effect by contacting and scraping.

[0054] like Figure 7 As shown, the combined use of the ultrasonic oscillator and the fan-shaped scraper 56 realizes a multi-level cleaning method; the ultrasonic wave can not only loosen the dirt, but also physically peel it off by mechanical means, thereby improving the cleaning efficiency.

Then, the inner ring bearings, outer ring bearings, and bearing flanges are assembled in sequence from the inside to the outside on the assembly platform of the frame 1 to obtain the hub bearings.

[0056] Working principle: Through the first clamping and transfer component 8, the second clamping and transfer component 11, and the third clamping and transfer component 14, the inner ring bearings, outer ring bearings, and bearing flanges are respectively clamped and transferred into the corresponding detection component 5. After being detected by the corresponding detection component 5, they are respectively transferred onto the first sorting conveyor belt 7, the second sorting conveyor belt 10, and the third sorting conveyor belt 13.

[0057] It should be noted that the three sorting lines for the inner ring bearings, outer ring bearings, and bearing flanges are carried out synchronously.

[0058] Through the display screen set on the frame 1, the feedback data of the control system is displayed, and appropriate inner ring bearings, outer ring bearings, and bearing flanges are selected on the first sorting conveyor belt 7, the second sorting conveyor belt 10, and the third sorting conveyor belt 13 respectively.
