Description

Technical Field

[0001] This utility model relates to the field of automobile assembly technology, and in particular to a lifting device for automobile assembly. Background Technology

[0002] Automobile assembly refers to the process of assembling qualified parts into a complete vehicle and assemblies such as engines and transmissions according to certain technical requirements. Spare tires, as part of automobile assembly, are relatively large and would be time-consuming and labor-intensive to handle manually.

[0003] According to the search, application number CN213262705U discloses a spare tire lifting device for automobile assembly. In this device, one end of the meshing connector is movably connected to the surface of the threaded screw, and the other end of the meshing connector is fixedly connected to one end of a first rotary motor. The other end of the first rotary motor is movably connected to one end of a semi-circular storage component. When the device is near the conveying device of the car frame to be assembled, the circular rotating table is lifted by a hydraulic cylinder and adjusted to an appropriate position by a third rotary motor. Then, the first rotary motor rotates, driving the semi-circular storage component to rotate. At this time, the spare tire can be easily taken out and assembled.

[0004] The above solution has the following shortcomings: when the device rotates the semi-circular storage component through the first motor, the spare tire is prone to detach from the semi-circular storage component under the action of gravity. Since the spare tire is circular, when the spare tire rotates out to a vertical position, it is easy to roll in the work area and collide with other items, and workers also need to spend time to retrieve it.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-4 As shown, this embodiment is a lifting device for automobile assembly, including:

[0031] The load-bearing component includes a base plate 1 and a support plate 2. The support plate 2 is fixedly connected to both sides of the upper end face of the base plate 1.

[0032] The limiting component includes a limiting frame 16, an airbag 18, a limiting plate 19, an elastic band 20, and a first spring 17.

[0033] A limiting frame 16 is fixedly connected to the upper end face of the base plate 1. Airbags 18 are fixedly connected to both sides of the inner wall of the limiting frame 16. A limiting plate 19 is fixedly connected to the opposite side of the two airbags 18. An elastic band 20 is fixedly connected between the two limiting plates 19. A first spring 17 is fixedly connected to the outer side of the limiting plate 19.

[0034] The airbag 18 and the first spring 17 can deform according to the degree of compression of the limiting plate 19, making the limiting plate 19 more stable when limiting the spare tire.

[0035] One end of the first spring 17, which is away from the limiting plate 19, is fixedly connected to the limiting frame 16. The airbag 18 and the first spring 17 are set to be in a vertically opposite position.

[0036] Working principle: First, when the spare tire is inserted vertically downward into the limiting plate 19, the first spring 17 and the airbag 18 will be compressed and deformed. At the same time, the elastic band 20 will also be stretched outward along with the limiting plate 19, so that the limiting plate 19 can better cooperate in limiting the spare tire and facilitate the subsequent transfer by the staff.

[0037] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment 1, and further includes a lifting component. The lifting component includes a fixed plate 3, a forward and reverse motor 4, a first rotating rod 5, a first gear 6, a toothed belt 7, a second gear 15, a connecting plate 8, a winding roller 9, a winding rope 10, a limiting rod 11, a support rod 12, a sleeve 14, a second spring 13, a through hole, and a second rotating rod 21.

[0038] A fixing plate 3 is fixedly connected to the right side of one of the support plates 2. A forward and reverse motor 4 is fixedly connected to the upper end of the fixing plate 3. A first rotating rod 5 is installed through the side wall of the support plate 2 at the output end of the forward and reverse motor 4. A first gear 6 is fixedly connected to the surface of the first rotating rod 5. A toothed belt 7 is meshed with the surface of the first gear 6. A second gear 15 is driven through the toothed belt 7. Two connecting plates 8 are fixedly connected to the surface of the toothed belt 7. A take-up roller 9 is rotatably connected to the inner walls of the two connecting plates 8. A take-up rope 10 is fixedly connected to the surface of the take-up roller 9. A limit rod 11 is fixedly connected to the other end of the take-up rope 10. A support rod 12 is fixedly connected to the bottom end of the limit rod 11. A sleeve 14 is slidably sleeved on the surface of the support rod 12. A second spring 13 is fixedly connected to one end of the support rod 12.

[0039] When the forward and reverse motor 4 drives the first gear 6 to transmit the toothed belt 7 clockwise, the installation structure in this device is lowered. Under the action of the second gear 15 and the second rotating rod 21, the spare tire can be lowered stably and vertically during the descent, so that the spare tire can be smoothly inserted into the limiting structure. At the same time, the model of the forward and reverse motor 4 is set to 6W-400W.

[0040] The second spring 13 is fixedly connected to the sleeve 14 at one end away from the support rod 12. The sleeve 14 is fixedly connected to the toothed belt 7 at one end away from the sleeve rod. A through hole is provided on the inner wall of the sleeve 14.

[0041] The second spring 13 enables the support plate 2 to slide left and right within the sleeve 14, allowing the limiting rod 11 to restrict and detach the spare tire.

[0042] The inner wall of the other support plate 2 is rotatably sleeved with the other end of the first rotating rod 5;

[0043] The inner wall of the second gear 15 is fixedly connected to the second rotating rod 21, and the two ends of the second rotating rod 21 rotate within the support plate 2 respectively;

[0044] Working principle: First, the worker above places the spare tire to be lowered onto the surface of the support rod 12 and the winding rope 10. The spare tire is then locked in place on one side by the limiting rod 11 between the limiting rod 11 and the sleeve 14, making the spare tire vertical. At this time, the forward and reverse motor 4 is started to control the first gear 6 to rotate counterclockwise, which drives the toothed belt 7. With the meshing support of the second toothed plate, the installation structure and the spare tire are lowered vertically and smoothly into the limiting plate 19. The forward and reverse motor 4 in this device operates once every 3 seconds. Therefore, when the limiting rod 11 is horizontal with the through hole in the middle of the spare tire, the forward and reverse motor 4 just stops working. At this time, the winding roller 9 is rotated to wind the winding rope 10 around the surface. During this process, the support plate 2 is pulled into the sleeve 14 to squeeze the second spring 13, so that the support rod 12 and the limiting rod 11 are smoothly disengaged from the spare tire. The above operation is repeated for the next spare tire.
