Description

Technical Field

[0001] The invention relates to the technical field of wheel hub assembly processing, in particular to a wheel hub bolt press-fitting device for a wheel hub assembly. Background Art

[0002] The wheel hub is a cylindrical metal component with the inner profile of the tire supporting the tire and the center mounted on the shaft. It is also called a rim, steel ring, wheel, or tire bell. When processing the wheel hub, a pressing device is required to press the end of the bolt into the flange hole of the wheel hub for fixing.

[0003] For example, the patent with publication number CN220445628U discloses a hub bolt press-fitting device for a hub assembly. The patent places the integrated structure of the hub and the brake disc at the middle of the top of the workbench, and drives two groups of clamping blocks to move inwards through a power mechanism. At this time, the integrated structure of the hub and the brake disc is clamped and fixed by the two groups of clamping blocks, and the staff rotates the clamping mechanism, and the integrated structure of the hub and the brake disc is clamped to prevent rotation through the cooperation of the clamping mechanism and the workbench. After the integrated structure of the hub and the brake disc is fixed, the hub bolts on the integrated structure of the hub and the brake disc can be press-fitted through the ballast assembly, which effectively avoids the rotation of the integrated structure of the hub and the brake disc when the hub bolts are pressed, and avoids the displacement of the hub bolts and the ballast assembly to cause damage to the integrated structure of the hub and the brake disc, thereby improving the use stability of the device. However, in actual use, it is still necessary to manually insert multiple bolts into the flange holes of the hub assembly one by one, resulting in a time-consuming and labor-intensive problem during the press-fitting process.

[0016] The present invention provides a hub bolt press-fitting device for a hub assembly, which has the following beneficial effects:

[0017] 1. The baffle plate and the supporting ring of the present invention will block the bottom of the wheel hub bolt in the hole at the outer end of the feed plate, so that the wheel hub bolt can be temporarily stored. When the wheel hub assembly is located at the lower part of the feed plate, as the hydraulic cylinder drives the lifting plate to move downward, the pressure rod can first squeeze the guide block to slide outward along the fixed plate. At this time, the baffle plate will not block the wheel hub bolt above, and the wheel hub bolt will just fall into the hole of the wheel hub assembly at the lower part. At the same time, the feed plate can also be used to guide the bolt to avoid skew during placement. After the wheel hub bolt is pressed into the wheel hub assembly, when the pressure rod moves up and separates from the guide block, the second magnet and the first magnet repel each other, thereby driving the vertical plate to slide and reset, so that the baffle plate blocks the bottom of the feed plate again, which is convenient for pressing the next bolt.

[0018] 2. The linear module of the present invention drives the support seat away from the hydraulic cylinder, which is beneficial to improving the safety during material replacement. After the wheel hub assembly is placed on the support seat, when the linear module drives the support seat to move toward the center of the hydraulic cylinder, the roller will move upward along the guide groove on the inner side of the frame, so that the lifting sleeve drives the lifting frame to move upward, and the connecting rod will squeeze the support plate to make it slide along the guide rod, so that the inside of the wheel hub assembly can be automatically supported and positioned. At the same time, since the lifting sleeve and the lifting frame are rotatably connected, when the support seat drives the workpiece to rotate, it will not affect the clamping state of the workpiece, which is beneficial to improving the stability of the subsequent rotation of the wheel hub assembly. Moreover, after pressing, when the linear module drives the support seat to move back, since the roller will roll to the lower part of the guide groove, the lifting sleeve will pull the support plate through the lifting frame and the connecting rod to automatically loosen the wheel hub assembly, thereby eliminating the need for additional operations and improving the convenience during material replacement.

[0019] 3. According to the present invention, after the hub bolt is press-fitted onto the hub assembly, as the hydraulic cylinder drives the lifting plate to move up, the pressure rod can be moved out from the inside of the feed plate, and after it is completely moved out, as the lifting plate continues to move up, the rack can fit with the ratchet, which will drive the ratchet to rotate. Therefore, the feed plate can be driven to rotate one-eighth of a circle through the damping shaft, the synchronous pulley set, the three-output shaft gear box, and the first bevel gear set. At the same time, the support seat can also be driven to rotate one-eighth of a circle through the driving shaft, the driving sleeve, and the second bevel gear set to press-fit the next hole. Subsequently, when the lifting plate moves down, the clamping plate will block the rotation of the ratchet, and the rack will squeeze the first spring seat and slide with the ratchet, thereby not controlling the rotation of the damping shaft. Therefore, after each press-fitting is completed, the position of the next press-fitting can be automatically adjusted, which is beneficial to improving the degree of automation of the equipment. Moreover, since the driving sleeve can slide on the driving shaft, it will not interfere with the movement of the support assembly.

[0020] 4. The present invention can store multiple bolts through the material holding frame. At the same time, the lifting plate will also drive the tooth plate and the rotating plate to touch each other during the lifting process, thereby pushing the rotating plate to rotate around the connecting shaft, and when the tooth portion of the tooth plate is separated from the rotating plate, the rotating plate can be rotated again under the action of the torsion spring, so that the rubber head rod can shake the bottom of the material holding frame, and the vibration of the material holding frame is amplified under the action of the second spring seat. At the same time, the material holding frame has a certain inclination, so under the action of vibration, the bolts inside it will gradually move downward, and when the bolts move to the end of the material holding frame, since the material holding frame here will not block the end of the bolts, the bolts will fall into the feeding tray below, thereby automatically replenishing the bolts inside the feeding tray, further improving the automation level of the equipment.

[0030] See also Figures 1 to 4 , a linear module 5 is arranged at the center of the interior of the frame 1, and a support assembly 6 is connected to the top of the linear module 5, the support assembly 6 includes a support seat 601 and a lifting frame 602, the middle part of the linear module 5 is rotatably connected to the support seat 601, and the interior of the support seat 601 is slidably connected to the lifting frame 602, the support assembly 6 also includes a lifting sleeve 603, a roller 604 and a guide groove 605, the outer side of the lifting frame 602 is rotatably connected to the lifting sleeve 603, and the two sides of the lifting sleeve 603 are rotatably connected to the rollers 604, the inner side of the frame 1 is provided with a guide groove 605, the support assembly 6 also includes a connecting rod 606, a support plate 607 and a guide rod 608, the top of the lifting frame 602 is rotatably connected to the connecting rod 606, and the top of the connecting rod 606 is rotatably connected to the support plate 607, and the middle part of the support plate 607 is slidably connected to the guide rod 608, and the guide rod 608 is fixedly connected to the support seat 601;

[0031] The specific operation is as follows: first, place the wheel hub assembly on the support seat 601 and adjust the position, then start the linear module 5 to drive the support seat 601 to move toward the hydraulic cylinder 2. During this process, the roller 604 will move upward along the guide groove 605 on the inner side of the frame 1, so that the lifting sleeve 603 drives the lifting frame 602 to move upward, and the connecting rod 606 will squeeze the support plate 607 to make it slide along the guide rod 608, so that the inside of the wheel hub assembly can be automatically tightened and positioned, which is beneficial to improve the stability of the subsequent rotation of the wheel hub assembly. When the wheel hub assembly is located at the lower part of the feeding tray 702, the hydraulic cylinder 2 will drive the lifting plate 3 to move downward. At this time, the pressure rod 4 will squeeze the guide block 705, so that when it slides outward along the fixed plate 703, the baffle 706 will not block the wheel hub bolts above, and the wheel hub bolts will just fall into the lower wheel hub assembly hole. At the same time, the feed tray 702 can also be used to guide the bolts to avoid skewing during placement.

Due to the mutual repulsion between the second magnet 708 and the first magnet 707, the vertical plate 704 will slide back, so that the baffle 706 will cover the bottom of the feed tray 702 again, which is convenient for pressing the next bolt. After the pressing is completed, when the linear module 5 drives the support seat 601 to move back, the roller 604 will roll to the lower part of the guide groove 605, so the lifting sleeve 603 will pull the support plate 607 through the lifting frame 602 and the connecting rod 606, so that it automatically loosens the hub assembly, thereby eliminating the need for additional operations, which is conducive to improving the convenience of the material replacement process.

[0032] See also Figure 2 , Figures 5 to 7The rear end of the lifting plate 3 is connected with a rotating assembly 8, and the rotating assembly 8 includes a first spring seat 801, a rack 802, a ratchet 803 and a card plate 804.

The rotating assembly 8 also includes a damping shaft 805, a synchronous pulley group 806, a three-axis gear box 807 and a first bevel gear group 808, a damping shaft 805 is arranged inside the ratchet 803, and the end of the damping shaft 805 is connected to a synchronous pulley group 806, a three-shaft gear box 807 is arranged on one side of the lower end of the synchronous pulley group 806, and the two ends of the three-shaft gear box 807 are arranged with a first bevel gear group 808, and the first bevel gear group 808 is fixedly connected to the feed tray 702, the rotating assembly 8 also includes a drive shaft 809, a drive sleeve 810 and a second bevel gear group 811, a middle side of the three-shaft gear box 807 is connected to a drive shaft 809, and the drive shaft 809 is The outer side is slidably connected with a driving sleeve 810, and the driving sleeve 810 is rotatably connected with the linear module 5. A second bevel gear set 811 is arranged on the outer side of one end of the first spring seat 801, and the second bevel gear set 811 is fixedly connected with the support seat 601. The tops of both ends of the frame 1 are provided with a vibration material assembly 9, and the vibration material assembly 9 includes a tooth plate 901, a support 902 and a connecting shaft 903. The tooth plates 901 are symmetrically arranged on both sides of the rear of the lifting plate 3, and the supports 902 are fixed on both sides of the rear of the frame 1. The upper end of the support 902 is rotatably connected with the connecting shaft 903. The vibration material assembly Component 9 further includes a torsion spring 904 and a rotating plate 905. A torsion spring 904 is fixed to the outer side of the connecting shaft 903, and the torsion spring 904 is fixedly connected to the support 902, and a rotating plate 905 is arranged at the end of the torsion spring 904. The vibrating material assembly 9 further includes a rubber head rod 906, a material holding frame 907 and a second spring seat 908. A rubber head rod 906 is arranged at one end of the rotating plate 905, and a material holding frame 907 is arranged on the top of the rubber head rod 906. Second spring seats 908 are arranged at both ends of the bottom of the second spring seat 908, and the second spring seat 908 is fixedly connected to the frame 1.

[0033] The specific operation is as follows: when the hydraulic cylinder 2 drives the lifting plate 3 to move downward, the clamping plate 804 will block the ratchet 803 from rotating, and the rack 802 will squeeze the first spring seat 801 and slide with the ratchet 803, thereby not controlling the damping shaft 805 to rotate. In this process, the lifting plate 3 will also drive the toothed plate 901 to touch the rotating plate 905, thereby pushing the rotating plate 905 to rotate around the connecting shaft 903, and when the tooth portion of the toothed plate 901 is separated from the rotating plate 905, the rotating plate 905 can be rotated again under the action of the torsion spring 904, so that the rubber head rod 906 can shake the bottom of the material receiving frame 907, and the vibration of the material receiving frame 907 is amplified under the action of the second spring seat 908. At the same time, the material receiving frame 907 has a certain inclination, so under the action of vibration, the bolts inside it will gradually move downward, and when the bolts move to the end of the material receiving frame 907, since the material receiving frame 907 here will not The end of the bolt is blocked, so the bolt will fall into the feed tray 702 below, thereby automatically replenishing the bolts inside the feed tray 702. After pressing, when the lifting plate 3 moves up, the rack 802 can fit with the ratchet 803, which will drive the ratchet 803 to rotate. Therefore, the damping shaft 805, the synchronous pulley group 806, the three-axis gear box 807, and the first bevel gear group 808 will drive the feed tray 702 to rotate one-eighth of a circle. At the same time, the drive shaft 809, the drive sleeve 810, and the second bevel gear group 811 can also drive the support seat 601 to rotate one-eighth of a circle to press the next hole. At the same time, since the lifting sleeve 603 and the lifting frame 602 are rotatably connected, when the support seat 601 drives the workpiece to rotate, it will not affect the clamping state of the workpiece. Therefore, after each press is completed, the position of the next press can be automatically adjusted, which is beneficial to improving the degree of automation of the equipment.

[0034] In summary, when using the wheel hub bolt pressing device of the wheel hub assembly, the wheel hub assembly is first placed on the support seat 601 and the position is adjusted, and then the linear module 5 is started to drive the support seat 601 to move toward the hydraulic cylinder 2. During this process, the roller 604 will move upward along the guide groove 605 on the inner side of the frame 1, so that the lifting sleeve 603 drives the lifting frame 602 to move upward, and the connecting rod 606 will squeeze the support plate 607 to make it slide along the guide rod 608, so that the inside of the wheel hub assembly can be automatically tightened and positioned. Secondly, when the wheel hub assembly is located at the lower part of the feeding tray 702, the hydraulic cylinder 2 will drive the lifting plate 3 to move downward. At this time, since the clamping plate 804 will block the ratchet 803 from rotating, the rack 802 will squeeze the first spring seat 801 and engage with the ratchet The wheel 803 slides, thereby not controlling the damping shaft 805 to rotate. During this process, the lifting plate 3 also drives the tooth plate 901 to touch the rotating plate 905, thereby pushing the rotating plate 905 to rotate around the connecting shaft 903, and when the tooth portion of the tooth plate 901 separates from the rotating plate 905, the rotating plate 905 can be rotated again under the action of the torsion spring 904, so that the rubber head rod 906 can shake the bottom of the material holding frame 907, and the vibration of the material holding frame 907 is amplified under the action of the second spring seat 908. At the same time, the material holding frame 907 has a certain inclination, so under the action of vibration, the bolts inside it will gradually move downwards, and when the bolts move to the end of the material holding frame 907, since the material holding frame 907 here will not The end of the bolt is blocked, so the bolt will fall into the feeding tray 702 below, thereby automatically replenishing the bolts inside the feeding tray 702. Then, when the pressure rod 4 squeezes the guide block 705 and makes it slide outward along the fixing plate 703, the baffle 706 will not block the wheel hub bolts above, and the wheel hub bolts will just fall into the wheel hub assembly hole at the bottom. At the same time, the feeding tray 702 can also be used to guide the bolts. Later, after the wheel hub bolts are pressed into the wheel hub assembly, as the hydraulic cylinder 2 drives the lifting plate 3 to move upward, the pressure rod 4 will separate from the guide block 705. Due to the mutual repulsion between the second magnet 708 and the first magnet 707, the vertical plate 704 is driven to slide back to its original position, so that the baffle 706 presses the bottom of the feeding tray 702 again. The lifting plate 3 is blocked, and then, as the lifting plate 3 continues to move upward, the rack 802 can be fitted with the ratchet 803, which will drive the ratchet 803 to rotate. Therefore, the damping shaft 805, the synchronous pulley group 806, the three-axis gear box 807, and the first bevel gear group 808 will drive the feed plate 702 to rotate one-eighth of a circle. At the same time, the driving shaft 809, the driving sleeve 810, and the second bevel gear group 811 can also drive the support seat 601 to rotate one-eighth of a circle, so as to press the next hole. Finally, after the press-fitting is completed, when the linear module 5 drives the support seat 601 to move back, the roller 604 will roll to the lower part of the guide groove 605, so the lifting sleeve 603 will pull the support plate 607 through the lifting frame 602 and the connecting rod 606.It automatically loosens the hub assembly so that it can be replaced.
