[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0030] refer to Figures 1-6 The tire assembly device shown is used for automobile manufacturing. It includes a chassis 1, a horizontal moving element 2 is mounted on the top of the chassis 1, a vertical lifting element 3 is mounted on the output end of the horizontal moving element 2, the vertical lifting element 3 is arranged perpendicularly to the horizontal moving element 2, and an assembly mechanism is mounted on the output end of the vertical lifting element 3.

[0031] The assembly mechanism includes a U-shaped frame 4 installed at the conveying end of the vertical lifting element 3. A rotating column 5 is provided between two closely spaced inner walls of the U-shaped frame 4. One end of the rotating column 5 is rotatably connected to the inner wall of the U-shaped frame 4 via a rotating rod. A motor 29 is installed on the side of the U-shaped frame 4. The output shaft of the motor 29 passes through the inner wall of the U-shaped frame 4 and is connected to the other side of the rotating column 5. An upper moving element 6 is installed on the top of the rotating column 5. An adjusting column 10 is installed on the side of the upper moving element 6. Four evenly arranged sliding components are installed on the annular side of the adjusting column 10. A rotating component is installed on each of the four sliding components. A bolt mounting cylinder 18 is installed on each of the four sliding components. An adjusting component is installed on the adjusting column 10. The adjusting component is connected to the four rotating components. The four rotating components are respectively installed in conjunction with the four bolt mounting cylinders 18. The four rotating components are all connected to the output end of the upper moving element 6 via a transmission component.

[0032] With the above structure, the transmission component can be moved by the upper moving element 6, thereby causing the four rotating components to drive the four bolt mounting cylinders 18 to rotate for pre-tightening. At the same time, the four rotating components can be moved by the adjusting component, thereby changing the position of the four bolt mounting cylinders 18, so as to meet the mounting bolts of different tire hub mounting holes, which is convenient to use.

[0033] The sliding assembly includes a rectangular sleeve 15 mounted on the annular side of the adjusting column 10. A rectangular column 16 is slidably mounted inside the rectangular sleeve 15. One end of the rectangular column 16 extends outside the rectangular sleeve 15 and is connected to a bearing 17. A bolt mounting sleeve 18 is fixedly mounted on the inner ring of the bearing 17. A limit unit is installed inside the rectangular sleeve 15. The rectangular column 16 is connected to the rotating assembly. The sliding assembly allows the bolt mounting sleeve 18 to rotate and slide, facilitating adjustment.

[0034] The limiting unit includes a limiting hole formed on the inner wall of the rectangular sleeve 15. A limiting rod 25 is slidably installed in the limiting hole. One end of the limiting rod 25 extends out of the limiting hole and connects to a limiting block 26. A limiting spring 27 is sleeved on the limiting rod 25. The two ends of the limiting spring 27 are respectively installed on the sides of the limiting block 26 and the rectangular sleeve 15 that are close to each other. Multiple limiting grooves are formed on the side of the rectangular column 16. The other end of the limiting rod 25 extends into one of the limiting grooves. By setting multiple limiting grooves, the position of the limiting groove can be set according to the position of different wheel hub mounting holes that need to be tightened. When the rectangular column 16 moves to the position, the limiting rod 25 enters the limiting groove under the action of the limiting spring 27, thus forming a fixed position, which facilitates subsequent adjustment.

[0035] The rotating assembly includes a U-shaped block 19 mounted on the side of the rectangular column 16. A rotating hole is formed on the inner wall of the U-shaped block 19 away from the rectangular sleeve 15. A rotating shaft is rotatably mounted in the rotating hole via a connecting bearing. A mounting bevel gear 21 is mounted at one end of the rotating shaft, and a spur gear 22 is mounted at the other end. A connecting bevel gear 20 is mounted on the end of the bolt mounting sleeve 18 near the mounting bevel gear 21. The connecting bevel gear 20 meshes with the mounting bevel gear 21. The U-shaped block 19 is connected to an adjusting assembly, and its side is connected to a transmission assembly. The rotation of the four spur gears 22 drives the rotation of the four mounting bevel gears 21, which in turn causes the four connecting bevel gears 20 to rotate, thereby causing the four bolt mounting sleeves 18 to rotate and pre-tighten the bolts.

[0036] The adjustment assembly includes an external thread 11 on the adjustment column 10, a threaded sleeve 12 threaded onto the external thread 11, an annular rotating groove on the outer annular part of the threaded sleeve 12, a rotating ring 13 rotatably mounted in the annular rotating groove, and four evenly circumferentially arranged push rods 14 rotatably mounted on the side of the rotating ring 13. The four push rods 14 are respectively rotatably mounted on the side of the four U-shaped blocks 19. By setting the threaded sleeve 12, rotating the threaded sleeve 12 can drive the rotating ring 13 to rotate and move in the annular rotating groove, thereby driving the four push rods 14 to push the four U-shaped blocks 19 to move, thus achieving simultaneous adjustment.

[0037] The transmission assembly includes four sliding posts 7 mounted on the output end of the upper moving element 6. Each of the four sliding posts 7 has a connecting post 8 slidably fitted onto it. Each of the four connecting posts 8 has a moving groove at its end near the adjusting post 10. A connecting rod 9 is slidably installed in each of the four moving grooves. The ends of the four connecting rods 9 away from the connecting posts 8 are respectively connected to the sides of four U-shaped blocks 19. A rack 23 is mounted on the side of each of the four connecting posts 8, and each rack 23 meshes with a spur gear 22. This transmission assembly allows for avoidance during adjustment. Simultaneously, the movement of the four sliding posts 7 causes the four connecting posts 8 to move, which in turn causes the four racks 23 to move, and ultimately rotates the four spur gears 22, facilitating simultaneous tightening.

[0038] A return spring 28 is installed on the side of the U-shaped block 19 away from the spur gear 22, and the end of the return spring 28 away from the U-shaped block 19 is installed on the side of the adjusting column 10. The return spring 28 facilitates the restoration of the U-shaped block 19 to its original state.

[0039] Multiple levers 24 are installed on the side of the threaded sleeve 12. The multiple levers 24 are evenly arranged, and the arrangement of the levers 24 facilitates the rotation of the threaded sleeve 12.

[0040] Two mounting boxes 30 are installed on the top of the chassis 1. The mounting boxes 30 are used to hold bolts.

[0041] A bracket 33 is mounted on the top of the chassis 1. Two U-shaped plates are mounted on the side of the chassis 1. A bearing roller 31 is mounted on the inner wall of the two U-shaped plates that are close to each other. A limit baffle 32 is mounted on the side of the two U-shaped plates that are far from each other. A limit fixing rod is mounted on the side of the two U-shaped plates that are far from the bracket 33. Two limit wheels are mounted on the side of the bracket 33. As in the prior art document CN107139651B, the bracket 33 can move by cooperating with the electric hoist and the slide rail. At the same time, the limit baffle 32, the bearing roller 31, the limit fixing rod, and the limit wheels are used to limit the tires.

[0042] Working principle of this invention:

[0043] In use, the tire is rolled onto the bearing roller 31 using a tool, so that the wheel hub mounting hole aligns with the brake disc mounting hole on the chassis. Then, the motor 29 is started, which causes the rotating column 5 to rotate, thereby causing the four U-shaped blocks 19 to rotate 90 degrees. Then, the bolts located in the placement box 30 are placed into the bolt mounting cylinder 18. The motor 29 is started, which causes the four U-shaped blocks 19 to return to a horizontal state. The four bolts are aligned with the mounting holes. Then, the upper moving element 6 is started. The output end of the upper moving element 6 retracts, which drives the four sliding columns 7 to move. The movement of the four sliding columns 7 drives the four connecting columns 8 to move, thereby causing the four racks 23 to move, which in turn causes the four spur gears 22 to rotate. The rotation of the four spur gears 22 drives the four mounting bevel gears 21 to rotate, which in turn causes the four connecting bevel gears 20 to rotate, thereby causing the four bolt mounting cylinders 18 to rotate and pre-tighten the bolts.

[0044] Since the radii of the circles formed by the mounting holes of different tires are different, when it is necessary to use mounting holes at different positions, the limiting block 26 can be pulled first to move it out of one of the limiting grooves. The limiting spring 27 will deform. Then, the actuating rod 24 will be rotated to make the threaded sleeve 12 move spirally on the external thread 11. The movement of the threaded sleeve 12 will drive the rotating ring 13 to rotate and move in the annular rotating groove, thereby driving the four push rods 14 to push the four U-shaped blocks 19 to move. The movement of the four U-shaped blocks 19 will drive the four rectangular pillars 16 to slide in the four rectangular sleeves 15 respectively. At the same time, the movement of the four U-shaped blocks 19 will drive the four connecting rods 9 and the four connecting pillars 8 to move. By setting multiple limiting grooves, the position of the limiting groove can be set according to the position of the different mounting holes of the tires to be tightened. When the rectangular pillar 16 moves to the position, the limiting rod 25 will enter the limiting groove under the action of the limiting spring 27 and be fixed, which will facilitate the adjustment later.

[0045] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
