DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0027] like Figure 1-7As shown, an aluminum alloy wheel decorative ring assembly device includes a first electric push rod 2, a support seat 3 for supporting a tire is fixedly installed on the top of the output shaft of the first electric push rod 2, a support frame 1, an assembly mechanism 5 for automatically expanding and sleeved rubber decorative rings is fixedly installed on the top of the inner wall of the support frame 1, and the assembly mechanism 5 includes a motor 501 fixedly connected to the top of the inner wall of the support frame 1, a threaded rod 502 is fixedly connected to the bottom end of the output shaft of the motor 501, the threaded rod 502 is sequentially penetrated and connected with a first connecting plate 503 and a second connecting plate 504, and is threadedly connected to the first connecting plate 503, six matching grooves are opened on the outer walls of the first connecting plate 503 and the second connecting plate 504, and the six grooves on the first connecting plate 503 are rotatably connected to the connecting rods 505, and the six grooves on the first connecting plate 503 are rotatably connected to the connecting rods 505. The connecting rods 505 are respectively connected to the six grooves on the second connecting disk 504 in a limiting sliding manner, the bottom end of the connecting rod 505 is fixedly connected with a lower pressure block 506, and the adjacent ends of the six lower pressure blocks 506 are fixedly connected with a hook 507 for hooking the rubber decorative ring, the bottom of the first connecting disk 503 is fixedly connected with a sleeve 509, the sleeve 509 is sleeved with the threaded rod 502, and the bottom of the sleeve 509 is fixedly connected with a plurality of abutment shafts 510, and the top of the second connecting disk 504 is commonly fixedly connected with a plurality of limiting rods 508, the plurality of limiting rods 508 pass through the top of the support frame 1, and the end extending outside the support frame 1 is installed with a first spring 511, and the distance between the bottom end of the abutment shaft 510 and the top of the second connecting disk 504 is adapted to the compression distance of the first spring 511.

[0028] Please refer to Figures 1 to 3It can be clearly seen that after the motor 501 is started, its output shaft will drive the threaded rod 502 to rotate. Since the second connecting plate 504 and the top of the support frame 1 are horizontally limited by the limiting rod 508, and the connecting rod 505 set between the second connecting plate 504 and the first connecting plate 503, the first connecting plate 503 is horizontally limited. At this time, under the rotation of the threaded rod 502, the first connecting plate 503 threadedly connected to the threaded rod 502 will move downward, and with the cooperation of the second connecting plate 504, it will push the connecting rod 505 to move downward and expand outward. At this time, the hooked decorative ring, under the expansion of the hook claws 507 driven by the six connecting rods 505, the inner diameter gradually increases and moves downward to the outer ring position of the wheel hub. In this process, the lower pressure block 506 will abut against the tire downward and make The top of the deflated tire sinks to make room for the decorative ring and expose the outer ring of the wheel hub, which is convenient for the installation of the decorative ring. Through the above process, the tire is pressed down and the decorative ring is automatically expanded and moved down. When the decorative ring moves down to the predetermined position, the abutment mechanism 6 is started and evenly abuts against part of the ring body of the decorative ring to make it stably sleeved on the outer ring of the wheel hub. At this time, with the continuous rotation of the threaded rod 502, the abutment shaft 510 under the sleeve 509 will abut against the second connecting disk 504 and push the second connecting disk 504 down. At this time, the first spring 511 is compressed, and the connecting rod 505 no longer expands. The hook 507 moves down with the pressing block 506 and gradually separates from the decorative ring to reset. After the decorative ring loses the tensile force of the hook 507, it contracts and is more stably clamped on the outer ring of the wheel hub.

[0029] Please refer to Figure 6 and Figure 7It can be clearly seen that a plurality of baffles 4 are mounted on the top of the support seat 3, and there are six baffles 4, and an abutment mechanism 6 is installed between two adjacent baffles 4, and there are three abutment mechanisms 6, and the abutment mechanism 6 includes a mounting plate 601, and the mounting plate 601 is fixedly connected between two adjacent baffles 4, and a second electric push rod 602 is installed on the mounting plate 601, and an output end of the second electric push rod 602 is fixedly connected with a first abutment block 603 for abutting a decorative ring at a specified position, and a slot 604 is provided in the first abutment block 603, and a second abutment block 605 is slidably connected in the slot 604, and a second spring 606 is fixedly connected between the second abutment block 605 and the inner wall of the slot 604, and when the decorative ring expands and drops to a predetermined position, the second electric push rod 602 follows the hook of the decorative ring The claw 507 automatically starts when it reaches the horizontal position of the outer ring of the wheel hub, and the extended output shaft will drive the first abutment block 603 to abut the decorative ring body between the two hook claws 507. With the cooperation of the three first abutment blocks 603, the decorative ring can be stably abutted on the outer ring of the wheel hub, which is convenient for the subsequent detachment and reset of the hook claw 507 and the decorative ring. When the connecting rod 505 drops to the predetermined position, the tire is pressed down to leave a larger gap. At this time, the elastic force of the second spring 606 will push the second abutment block 605 out when the second abutment block 605 loses the abutment on the top of the wheel, thereby extending the abutment area of ​​the decorative ring, and better abutting the rubber decorative ring after the drop, thereby ensuring that when the hook claw 507 is separated from the decorative ring, the decorative ring is still abutted and limited on the outer edge of the wheel hub. Example 2

[0030] Further improvements are made based on Example 1. Please refer to Figure 3 It can be clearly seen that the distance between the bottom end of the abutment shaft 510 and the top of the second connecting plate 504 is adapted to the compression distance of the first spring 511. Through the above arrangement, it can be ensured that when the second connecting plate 504 descends, the first spring 511 is stably compressed, and when the abutment shaft 510 does not abut the second connecting plate 504, the second connecting plate 504 maintains a stable effect within a certain range, so that the expansion and downward movement process of the decorative ring can be carried out stably and orderly.

[0031] The threaded rod 502 is fixedly connected to a mounting block 8 at its bottom end below the second connecting plate 504. A brush 9 for applying lubricating oil to the outer ring of the wheel is provided at one end of the mounting block 8 close to the hook 507. The continuous rotation of the motor 501 can drive the mounting block 8 and the brush 9 to rotate, so that the brush 9 applies lubricating oil to the outer ring of the wheel hub. On the one hand, it reduces the friction force during the installation of the decorative ring. On the other hand, it reduces the friction force between the decorative ring and the wheel and the hub after installation, thereby extending the service life of the decorative ring. Example 3

[0032] As a supplement to Example 1, please refer to Figure 4and Figure 5 It can be clearly seen that

[0033] A limiting mechanism 7 for limiting the decorative ring is provided in the lower pressing block 506, and the limiting mechanism 7 includes a first cavity 701 and a second cavity 702. The first cavity 701 and the second cavity 702 are both provided in the lower pressing block 506, and the first cavity 701 is communicated with the second cavity 702. A piston in the first cavity 701 is connected to a first piston block 703, and one end of the first piston block 703 away from the first cavity 701 abuts against the inner wall of the baffle 4, and a stopper 704 is slidably connected in the second cavity 702, and one end of the stopper 704 extends into the first cavity 701 and is fixedly connected to the second piston The block 706, the stopper 704 and the solenoid valve 705 are provided with an exhaust hole, and the solenoid valve 705 is sealed in the exhaust hole, the second piston block 706 is connected to the piston of the first cavity 701, and is fixedly connected to the inner wall of the first cavity 701 with a third spring 709, and the two ends of the third spring 709 are respectively sleeved with a positioning shaft 707 and a trigger switch 708, and the first cavity 701 and the trigger switch 708 are arranged relatively, the positioning shaft 707 is fixedly connected to the second piston block 706, and the trigger switch 708 is fixedly connected to the inner wall of the first cavity 701. When the connecting rod 505 drives the pressing block down, the second piston block 706 is connected to the second cavity 701, and the trigger switch 708 is fixedly connected to the inner wall of the first cavity 701. When the decorative ring 506 is expanded, the first piston block 703 is abutted by the baffle 4 and contracts into the first cavity 701. At this time, the compressed air in the first cavity 701 will push the second piston block 706 and the block 704 to move. The block 704 will gradually extend out of the second cavity 702 and cover the top of the decorative ring in the hook 507 to avoid the decorative ring from being separated from the hook 507 and popping out during the stretching process. This ensures that the decorative ring can be stretched, moved down and sleeved safely and stably. During this period, the second piston block 706 will compress the third spring 709 under the pressure of compressed air. The positioning shaft 707 is made to abut against the trigger switch 708, thereby achieving the effect of triggering the trigger switch 708. When the trigger switch 708 is triggered, the solenoid valve 705 will be opened. At this time, compressed air will be discharged from the solenoid valve 705 and the block 704. On the one hand, it can prevent the block 704 from still covering the decorative ring during the downward movement of the hook 507, resulting in the decorative ring being unable to be smoothly separated from the hook 507. On the other hand, the blown air can blow away the dust particles on the wheel hub and the decorative strip, thereby improving the assembly effect of the decorative ring. Secondly, the limiting mechanism 7 can also be smoothly reset to work next time.

[0034] The moving distance of the first piston block 703 is matched with the maximum compression distance of the third spring 709 and the maximum extension distance of the stop block 704. Through this arrangement, it can be achieved that under the premise that the first piston block 703 is in contact with the baffle 4, when the connecting rod 505 pushes the pressing block 506 to continue to expand and descend, it can be ensured that the process of the first piston block 703 retracting into the first cavity 701, the process of the third spring 709 compressing, and the process of the stop block 704 extending out of the second cavity 702 to cover the expanded decorative ring can be carried out stably.

[0035] The pressing block 506 is located at one end of the hook 507 and is fixedly connected to an air guide block 710. The bottom of the air guide block 710 is set as an inclined surface and is located above the end of the second cavity 702 close to the hook 507. Through this setting, when the air in the first cavity 701 is blown out through the second cavity 702, the air can be guided to blow downward to the edge of the contour, thereby blowing away surface dust and foreign matter, and preventing dust and foreign matter from affecting the sealing effect of the decorative ring sleeve.

[0036] The top shape of the hook 507 is set to be an arc, and the depth of the hook 507 is adapted to the width of the decorative ring. Through this setting, the hook 507 can be prevented from damaging the surface of the decorative ring when the rubber decorative ring is separated from the hook 507 and inserted into the wheel hub.

[0037] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
