Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, and in particular to a dual-channel assembly equipment for wheel hub bearing balls. Background Technology

[0002] Wheel hub bearing ball assembly is a process of precisely embedding balls into the raceway between the inner and outer rings of the wheel hub bearing. It usually requires steps such as loading, positioning, and pushing to install the balls into the raceway in a preset number and arrangement to ensure that the balls can roll smoothly within the raceway. The reason for this assembly is that the balls are the core transmission component of the wheel hub bearing. After assembly, they can convert the sliding friction between the inner and outer rings of the bearing into rolling friction, reduce the frictional resistance when the wheel hub rotates, and at the same time ensure that the wheel stably supports the weight of the vehicle body and accurately transmits steering force during driving. Currently, wheel hub bearing ball assembly mostly adopts a single-channel assembly mode. In this mode, the balls need to be transported to a single unloading section via a conveyor track, and then the loading, positioning and pushing are completed sequentially through a single pressing station. The overall assembly process is serial, and only a single wheel hub bearing can be unloaded and assembled at a time. The assembly rhythm depends entirely on the operating efficiency of a single channel, resulting in a slow overall assembly speed, which is difficult to meet the needs of large-scale production. In actual assembly, the single-channel mode has operational drawbacks. During assembly, the cage must first be placed on the protrusion of the support base. At this point, an annular gap is formed between the protrusion of the support base and the cage. This gap is designed to be larger than the diameter of the bearing balls (to leave room for manual assembly of the wheel hub bearing later). The cage is also slightly flared. After the balls fall into the unloading section through the upper unloading pipe, they slide into the annular gap between the protrusion of the support base and the cage. The support base protrusion rotates one revolution synchronously, theoretically distributing the balls evenly in the annular gap. However, in actual use, because the annular gap is larger than the diameter of the balls, and the support base protrusion vibrates during rotation, the falling balls are difficult to adhere to the inner wall of the slightly flared cage, resulting in misalignment or even multiple balls falling. Ultimately, workers still need to manually adjust the ball positions during wheel hub bearing assembly, further reducing assembly efficiency.

[0003] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0019] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-2 and Figures 5-7 As shown, this embodiment of the invention provides a dual-channel assembly equipment for wheel hub bearing balls, including a support assembly 1. The support assembly 1 includes a worktable 11, and a mounting cover 12 is fixed on the worktable 11. The mounting cover 12 has an auxiliary plate, and a vibratory feeder 13 is fixed on the auxiliary plate. The vibratory feeder 13 contains bearing balls. A feeding assembly 3 is provided on the bottom surface of the auxiliary plate. The feeding assembly 3 is used to unload the bearing balls, and the feeding assembly 3 includes two sets of mounting crossbars 31 fixed on the bottom surface of the auxiliary plate. A connecting rod 32 is connected between the two sets of mounting crossbars 31. Furthermore, a feeding section is provided on the bottom surface of the auxiliary plate. The feeding section includes a feeding component 33 embedded on the bottom surface of the auxiliary plate. The feeding component 33 is used to receive bearing balls falling from the vibratory plate 13. A dropping platform 35 is slidably provided on the connecting rod 32. The dropping platform 35 has two sets of through holes for accommodating bearing balls. Two sets of dropping nozzles 36 are connected to the bottom surface of the dropping platform 35 at the corresponding positions of the through holes. The dropping platform 35 is used to carry and distribute bearing balls. Feeding to different dropping nozzles 36 is achieved by sliding. A cylinder 34 is fixed on the bottom surface of a set of mounting crossbeams 31. The telescopic end of the cylinder 34 is connected to the side of the dropping platform 35. The cylinder 34 is adapted to align the two sets of through holes with the feeding component 33 respectively. The cylinder 34 provides power for the sliding of the dropping platform 35. By telescopically moving the dropping platform 35 along the connecting rod 32, the feeding of different dropping nozzles 36 is switched. Simultaneously, a conveying section is connected to both sets of discharge nozzles 36. This conveying section includes discharge hoses 37 connected to both sets of discharge nozzles 36. Bearing balls falling into the discharge nozzles 36 are suitable for being conveyed from the discharge table 35 to the discharge hoses 37. The discharge hoses 37 serve as the conveying channel for the bearing balls, and a discharge section 310 is connected to one end of each discharge hose 37. The discharge section 310 is the final discharge component for the bearing balls, conveying them to the assembly position of the wheel hub bearing. The two sets of discharge sections 310 are connected to sleeves... There is a support plate 313, and a sensing part is sleeved on the two sets of material discharge hoses 37. The sensing part includes a sensor 38 that is sleeved on the two sets of material discharge hoses 37. The sensor 38 is electrically connected to the cylinder 34. The sensor 38 is used to sense whether there are bearing balls at the position where the sensor 38 is located on the material discharge hose 37, so as to control the drive cylinder 34 to drive the material discharge table 35 to slide along the straight direction of the connecting rod 32, so as to supply bearing balls to the two sets of material discharge hoses 37 respectively. A sensor 39 is fixedly sleeved on the material discharge hose 37 near the material discharge section 310. This sensor 39 senses whether there are bearing balls at its position on the material discharge hose 37. Two sets of cylinders 311 are fixed to the bottom surface of the support plate 313. A sealing member 312 is fixed to the telescopic end of each cylinder 311. An insertion hole (not shown in the figure) matching the size of the sealing member 312 is provided on the surface of the material discharge section 310. The sealing member 312 is used to seal... The discharge port of the discharge section 310 is blocked, and the timing of the discharge of the bearing balls is controlled. Cylinder 5 311 provides power for the movement of the sealing component 312. By extending and retracting, the sealing component 312 is inserted into or withdrawn from the insertion hole, thereby blocking or opening the discharge port of the discharge section 310. In actual use, sensor 2 39 is used to detect whether there are bearing balls near the discharge hose 37 near the discharge section 310, and then control the action of cylinder 5 311 to block or open the discharge port of the discharge section 310.

[0021] like Figures 6-8 and Figures 10-11 As shown, a rotating assembly 4 for assisting in the assembly of bearing balls is provided on the worktable 11. This rotating assembly 4 can drive the bearing ball cage and other components to rotate, allowing the bearing balls to be assembled more evenly into their corresponding positions, improving assembly efficiency and quality. The rotating assembly 4 includes a support part provided on the worktable 11. The support part includes a support platform 41 fixed on the worktable 11. There is a gap between the support platform 41 and the worktable 11, and a support seat 42 is provided on the support platform 41. The bottom surface of the support seat 42 is open. A support seat 418 is provided at the center bearing of the support seat 42, and a protrusion seat 43 is integrally embedded on the support seat 418. In actual use, the bearing ball cage is manually placed on the protrusion seat 43. An annular inner groove adapted to the bottom surface of the cage is opened on the upper surface of the support seat 418 to improve the placement stability of the cage. At this time, there is a gap between the cage and the protrusion seat 43 for the bearing balls to fall (see reference). Figure 8 ); Meanwhile, a vertically arranged rotating shaft 46 is fixed on the bottom surface of the protruding seat 43, and a drive unit is provided on the worktable 11. The drive unit includes a motor 44 fixed on the worktable 11 and located below the support platform 41. A gear 45 is fixed to the output end of the motor 44, and a gear 47 that meshes with the gear 45 is fixedly sleeved on the rotating shaft 46. The gear 47 receives the power transmitted by the gear 45 and drives the rotating shaft 46 to rotate, thereby causing the support seat 418 and the bearing ball cage to rotate.

[0022] like Figures 3-7 As shown, a moving component 2 is positioned on one side of the rotating component 4 on the worktable 11. This moving component 2 is used to move the blanking part 310 to a designated assembly position, ensuring that the bearing balls can accurately fall into the gap between the cage and the protrusion seat 43, thus improving assembly accuracy. The moving component 2 includes a horizontal moving part on the worktable 11, which includes a base 21 fixed to the worktable 11. A side baffle 22 is fixed to one side of the base 21, and a sliding table 23 is fixed to the worktable 11. Furthermore, a cylinder 24 is slidably mounted on the sliding table 23. The telescopic end of the cylinder 24 is fixedly connected to the side baffle 22, and a T-shaped mounting plate 25 is fixed on the upper surface of the cylinder 24. The cylinder 24 provides horizontal power to the horizontal moving part, and drives the mounting plate 25 to move horizontally through telescopic movement. Slider 27 is fixed on the bottom surfaces of both sides of the mounting plate 25. At the same time, a slide rail 26 adapted to the slider 27 is fixed at the corresponding position on the base 21. The slider 27 and the slide rail 26 cooperate to make the mounting plate 25 move more smoothly and steadily when moving horizontally, and reduce frictional resistance. Meanwhile, a vertical moving part is provided on the mounting plate 25. The vertical moving part includes two sets of symmetrical and vertically arranged support columns 28 fixed on the mounting plate 25. A support panel 29 is connected to one end of the two sets of support columns 28. A vertically arranged cylinder 210 is fixed on the support panel 29. The telescopic end of the cylinder 210 moves through the support panel 29 and is connected to the bearing plate 313. The cylinder 210 provides vertical power to the vertical moving part, and drives the bearing plate 313 to move vertically through telescopic movement. The bearing plate 313 is simultaneously movably sleeved on the two sets of support columns 28. The support columns 28 guide the vertical movement of the bearing plate 313, ensuring that the bearing plate 313 can move smoothly in the vertical direction.

[0023] To address the issue of excessive ball misalignment and drop due to large gaps between the cage and the support base protrusions, coupled with rotational vibration, requiring manual adjustment and reducing efficiency, such as... Figures 8-11 As shown, an adjustment component 5 is provided on the support 418. The adjustment component 5 can dynamically adjust the distance between the retainer and the protrusion 43, while suppressing rotational vibration and ensuring that the bearing balls fall into the gap. The adjustment component 5 includes a lifting part provided on the rotating shaft 46. The lifting part includes a rotating seat 521 that is slidably sleeved with the rotating shaft 46 through a rod (not shown in the figure). At the same time, multiple sets of equally spaced pins 461 are integrally provided on the surface of the rotating shaft 46 along its circumference. The rod is provided with a notch groove that matches the pins 461. That is, in actual use, the rotating seat 521 can move up and down linearly along the straight direction of the pins 461 through the notch groove, and is suitable for rotating synchronously with the rotating shaft 46. Furthermore, a base 520 is connected to the bottom surface of the rotating seat 521 by a bearing. An integrally formed arc-shaped member 518 extends upward from the upper surface of the rotating seat 521. The surface of the arc-shaped member 518 has a certain slope, and four sets of the arc-shaped member 518 are provided and symmetrically arranged. The arc-shaped member 518 is movably connected through the support seat 418. The arc-shaped member 518 is used to adjust the distance between the retainer and the protrusion 43. At the same time, an arc-shaped groove (not shown in the figure) is provided on the support seat 418 for the arc-shaped member 518 to pass through. In actual use, the arc-shaped member 518 is adapted to slide up and down along the vertical direction of the arc-shaped groove to change the distance between the retainer and the protrusion of the support base. Furthermore, a positioning part is provided on the support base 42. This positioning part is used to initially position the base 520, ensuring the structural stability of the adjustment component 5 in its initial state. The positioning part includes two sets of opposing support rods 522 fixed on the support platform 41. A spring 523 is sleeved on the support rod 522. One end of the spring 523 is connected to the bottom surface of the base 520, and the support rod 522 is movably inserted through the base 520. The spring 523 provides initial support force to the base 520, keeping the base 520 in its initial position when no external force is applied. Hollow limiting seats 56 are fixed on both sides of the base 520 on the support platform 41. A slide table 57 is slidably arranged inside the base 56. The slide table 57 has two sets of oppositely arranged slope grooves 58. At the same time, a contact end 55 extending into the slope groove 58 is fixed on the bottom surface of the base 520. The contact end 55 is used to contact the slope groove 58 of the slide table 57, converting the horizontal movement of the slide table 57 into the vertical movement of the base 520, thereby realizing the lifting control of the arc-shaped part 518. The contact position between the contact end 55 and the slope groove 58 is spherical. The spherical structure can reduce the frictional resistance between the contact end 55 and the slope groove 58, making the force transmission smoother. In the initial state, the base 520 is subjected to the action of the spring 523, so that one end of the contact end 55 contacts the bottom end of the slope groove 58. Meanwhile, two sets of reset parts are fixed on the inner wall of the support base 42 to reset the two sets of slides 57. The two sets of reset parts act on the two sets of slides 57 respectively. They are used to reset the slides 57 to the initial position after the external force disappears, so as to ensure the cyclic use of the adjustment component 5. The reset part includes two sets of positioning rods 59 fixed on the inner wall of the support base 42. Spring 510 is sleeved on the two sets of positioning rods 59. Connecting rod 511 is movably sleeved on the two sets of positioning rods 59. One end of spring 510 is connected to the inner wall of the support base 42, and the other end is connected to the side of connecting rod 511. The slide 57 is fixed to the connecting rod 511. In the initial state, spring 510 has a limiting effect on the slide 57 so that one end of the contact end 55 contacts the bottom end of the slope groove 58 simultaneously. Furthermore, a pressing part is provided on the support plate 313. The pressing part includes a horizontal frame 512 fixed on both sides of the support plate 313. A pressing rod 513 is vertically and movably arranged near both ends of the horizontal frame 512. Two sets of opposing positioning columns 51 are fixed on the support base 42. The positioning column 51 is hollow and a vertically arranged contact rod 52 is movably arranged through the positioning column 51. The contact rod 52 is used to convert the vertical pressure of the pressing rod 513 into the horizontal movement of the slide table 57. The slope groove 58 is used to contact the contact end 55 and the contact rod 52. By changing the slope, the horizontal movement of the contact end 55 and the contact rod 52 is converted into the vertical movement of the slide table 57, thereby driving the base 520 and the arc-shaped part 518 to rise and fall. The two ends of the contact rod 52 are respectively installed through the positioning post 51, and its top end is adapted to contact the pressing rod 513. One end of the contact rod 52 passes through the support base 42 and contacts another set of slope grooves 58 on the slide table 57. The contact position between the contact rod 52 and the slope groove 58 is spherical. The spherical structure reduces the frictional resistance between the contact rod 52 and the slope groove 58, making the force transmission more efficient. A spring 53 is sleeved on the contact rod 52 inside the positioning post 51. The spring 53 is a contact spring. The rod 52 provides a restoring force. When the pressure of the pressing rod 513 is removed, it pushes the contact rod 52 back to the initial position. At the same time, a washer 54 is fixedly sleeved on the contact rod 52 inside the positioning post 51. The washer 54 is set to fit against the bottom surface of the inner wall of the positioning post 51. One end of the spring 53 is connected to the washer 54, and the other end is connected to the top surface of the inner wall of the positioning post 51. The contact rod 52 is adapted to contact the high end of the slope groove 58 under the action of the spring 53. Furthermore, a fine-tuning section is provided on the horizontal frame 512. This section is used to precisely adjust the downward movement of the pressing rod 513, thereby controlling the extension of the arc-shaped member 518 and achieving precise adjustment of the distance between the retainer and the protruding seat 43. The fine-tuning section includes a cylinder 6 515 fixed on the horizontal frame 512. An initial rod 514 is fixed to the telescopic end of the cylinder 6 515. One end of the two sets of pressing rods 513 is connected to the bottom surface of the initial rod 514. The initial rod 514 is used to connect the cylinder 6 515 and the pressing rods 513, transmitting the power of the cylinder 6 515 to the pressing rods 513. At the same time, a laser rangefinder sensor 516 is fixed on the horizontal frame 512, and a receiving end 517 is fixed at a corresponding position on the bottom surface of the initial rod 514. The receiving end 517 is used to receive laser light. The beam emitted by the distance sensor 516 converts the distance signal into a recognizable electrical signal, which is then transmitted to the controller mounted on the workbench 11. The controller regulates the extension and retraction stroke of the cylinder 515 to detect the distance between the initial rod 514 and the horizontal frame 512. Based on different distances, the degree of downward movement of the pressing rod 513 with the moving component 2 can be determined, ultimately achieving precise control over the extension of the arc-shaped part 518. This ensures that the gap between the cage and the protrusion seat 43 is adjusted correctly, meeting the clearance requirements for the assembly of bearing balls of different specifications. This allows the bearing balls to always fall accurately into the cage raceway, solving the problem of ball offset and multiple drops caused by gap errors, and realizing automated and high-precision assembly of bearing balls of different models.

[0024] Working principle: After the equipment starts, the vibratory feeder 13 arranges the internal bearing balls in an orderly manner through high-frequency vibration. The balls are then guided through the feed component 33 on the bottom of the auxiliary plate into one set of through holes in the discharge table 35 (in the initial state, the cylinder 34 drives the discharge table 35 to align the through holes with the feed component 33). At this time, the discharge nozzle 36 at the bottom of the discharge table 35 is connected to the through hole, and the bearing balls enter the discharge hose 37 through the discharge nozzle 36. The sensor 38, which is sleeved on the discharge hose 37, monitors the status of the balls in the hose in real time. When it detects that there are enough balls in the current discharge hose 37, it immediately sends a switching signal to the cylinder 34. The telescopic end of the cylinder 34 drives the discharge table 35 to slide along the connecting rod 32, aligning the other set of through holes with the feed component 33, thereby switching the supply of the other set of discharge hoses 37. This forms a dual-channel continuous and alternating material conveying process, providing a stable supply of balls for subsequent assembly.

[0025] When the bearing balls in the discharge hose 37 accumulate to a position close to the discharge section 310, sensor 2 39 detects the balls and sends an action signal to cylinder 5 311; the telescopic end of cylinder 5 311 retracts, causing the sealing component 312 to exit from the insertion hole of the discharge section 310, thus releasing the blockage of the discharge port. At the same time, the moving component 2 is activated synchronously: the telescopic end of cylinder 1 24 of the horizontal moving component pushes the T-shaped mounting plate 25, causing the mounting plate 25 to slide smoothly horizontally along the slide rail 26 on the base 21 via the bottom slider 27, adjusting the horizontal position of the discharge section 310; the telescopic end of cylinder 2 210 of the vertical moving component drives the bearing plate 313 to move vertically along the support column 28, ultimately aligning the two sets of discharge sections 310 with the assembly gap between the cage and the protrusion seat 43 in the rotating component 4, providing precise spatial positioning for the falling assembly of the bearing balls.

[0026] The bearing ball cage is manually fitted onto the protrusion 43. The annular groove on the surface of the support 418 fits tightly against the bottom surface of the cage, ensuring stable placement of the cage and a uniform discharge gap between the cage and the protrusion 43. Subsequently, the motor 44 of the drive unit starts, and its output drives the gear 45 to rotate. The gear 45 meshes with the gear 47 on the rotating shaft 46, causing the rotating shaft 46 to drive the support 418, the protrusion 43, and the cage to rotate synchronously, using rotational force to provide the power basis for the uniform distribution of the bearing balls.

[0027] Before the cage rotation assembly process, the adjustment component 5 intervenes synchronously: when the moving component 2 moves the bearing plate 313 down, the pressing rod 513 on the horizontal frame 512 contacts the contact rod 52, the contact rod 52 moves down along the positioning column 51 and pushes the slide table 57 to slide horizontally along the limiting seat 56. The slope groove 58 of the slide table 57 pushes the contact end 55 upward, which in turn drives the base 520 and the rotating seat 521 to move upward along the pin block 461 on the rotating shaft 46, so that the arc-shaped part 518 slides upward along the arc-shaped waist groove of the support seat 418, lifting the cage to reduce the gap between it and the protruding seat 43; at the same time, the laser range sensor 516 detects the distance between the initial rod 514 and the horizontal frame 512 in real time through the receiver 517, converts the distance signal into an electrical signal and transmits it to the controller. The controller adjusts the extension and retraction stroke of the cylinder 515 to achieve micron-level control of the extension amount of the arc-shaped part 518, thereby adapting to the gap requirements of different specifications of cages, and effectively suppressing the vibration when the cage rotates, avoiding ball offset and excessive drop.

[0028] During the continuous rotation of the cage, the blanking section 310 continuously feeds the bearing balls into the gap between the cage and the protrusion seat 43. The rotational force of the cage ensures the balls are evenly distributed within the raceway, completing the dual-channel synchronous assembly. When assembly is complete or adjustment is needed, the moving component 2 moves the bearing plate 313 upwards, and the pressure of the pressing rod 513 on the contact rod 52 disappears. Spring 1 53 pushes the contact rod 52 back to its original position, spring 2 510 pushes the slide table 57 back to its original position, and spring 3 523 pushes the base 520, rotating seat 521, and arc-shaped component 518 downwards, restoring the gap between the cage and the protrusion seat 43 to its initial state, completing one assembly cycle. Through the coordinated operation of these components, automated, high-precision dual-channel assembly of bearing balls of different models is ultimately achieved, solving the problems of low efficiency and poor precision associated with traditional manual adjustments.
