[0029] The following combines the drawings in the embodiments of the present utility model to clearly and completely describe the technical solutions in the embodiments of the present utility model. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0030] As Figure 1 and Figure 2 shown, this embodiment provides a vehicle body turnover frame, which includes a left turnover frame 100, a right turnover frame 200, a square frame, a fixed clamp 500, an auxiliary wheel 700 and a driving device 600. Among them, both the left turnover frame 100 and the right turnover frame 200 are circular rings. The auxiliary wheel 700 is fixedly installed on the ground through a support, and the auxiliary wheel 700 can rotate on the support. The left turnover frame 100 and the right turnover frame 200 are placed on the auxiliary wheel 700. The driving device 600 is also placed on the ground, and the driving device 600 can drive the left turnover frame 100 to rotate. The left turnover frame 100 and the right turnover frame 200 are connected together through a square frame, and the right turnover frame 200 rotates with the left turnover frame 100. The vehicle body is fixed on the left turnover frame 100, the direction frame, and the right turnover frame 200 through the fixed clamp 500, and the vehicle body also rotates with the left turnover frame 100 to generate turnover.

[0031] Specifically, in this embodiment, the left turnover frame 100 includes an upper left bracket and a lower left bracket that are respectively semi-circular rings, and the upper left bracket and the lower left bracket are detachably connected; the right turnover frame 200 includes an upper right bracket and a lower right bracket that are respectively semi-circular rings, and the upper right bracket and the lower right bracket are detachably connected; the square frame includes an upper square frame 300 and a lower square frame 400. The two ends of the upper square frame 300 are respectively fixedly connected to the upper right bracket and the upper left bracket, and the two ends of the lower square frame 400 are respectively fixedly connected to the lower right bracket and the lower left bracket.

[0032] The fixed fixture 500 is detachably mounted on the square frame. These fixed fixtures 500 are used to fix the vehicle body. Similarly, the fixed fixture 500 can also be fixedly mounted on the left turning frame 100 and / or the right turning frame 200 through the connecting rod 800. The position of the fixed fixture 500 can be changed according to the vehicle model. At the same time, the number of the fixed fixtures 500 can also be changed according to the vehicle model. However, it is necessary to ensure that the clamping position of the vehicle body on the vehicle body turning frame is reasonable, the center of gravity is stable, and the rotation is stable. Specifically, in this embodiment, the fixed fixture 500 includes a mounting seat 510 and a threaded rod 530. A threaded sleeve 520 is provided on the mounting seat 510. The threaded rod 530 is screwed with the threaded sleeve 520. The vehicle body is fixed on the vehicle body rotating frame through the mutual cooperation between multiple fixed fixtures 500.

[0033] In this embodiment, as Figure 1 and Figure 2 shown, the driving device 600 includes a driving motor 610, a reduction box 620 and a sprocket. The output shaft of the driving motor 610 is fixedly connected to the input end of the reduction box 620. The output end of the reduction box 620 is fixedly connected to the sprocket. The sprocket is meshed with the chain 110. The chain 110 is arranged outside the left turning frame 100. The driving motor 610 drives the left turning frame 100 to rotate through the chain 110, thereby realizing the rotation of the vehicle body. The driving motor 610 and the reduction box 620 can adopt mature products on the market. In addition, the reduction box 620 needs to have a braking function. In this way, when the vehicle body rotates to the appropriate angle, by cutting off the power, the driving motor 610 stops rotating, and the reduction box 620 is also braked accordingly, resulting in the vehicle body turning frame no longer rotating. That is to say, in this embodiment, the stop function of the vehicle body turning frame is realized through the reduction box 620 with a braking function and the power-off driving motor 610, so as to avoid the operator from being injured during the vehicle body maintenance process.

[0034] In this embodiment, four auxiliary wheels 700 are provided. Each auxiliary wheel 700 is respectively configured with a support. The auxiliary wheel 700 is rotatably connected to the support. Two of the auxiliary wheels 700 are used to support the left turning frame 100, and the other two auxiliary wheels 700 are used to support the right turning frame 200.

[0035] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
