[0002] As we all know, in the process of tire R&D, in order to reduce the risk of failure in developing new patterns and increase the iteration speed of tire pattern solutions, the method of engraving on smooth tires is generally adopted first, and samples are produced first for testing and analysis, so as to use objective indicators to guide the improvement plan of tire patterns, thereby greatly shortening the R&D cycle. How to improve the efficiency of this process is of great significance to the R&D of tire patterns.

[0003] Existing related patents mainly focus on how to install and fix tires and facilitate tire carving, but there are some shortcomings, such as: manpower is required to lift the tires and rims to a certain height, which makes installation difficult; the tires are difficult to effectively fix during manual carving, resulting in low carving efficiency; the equipment structure is too complicated, which makes it inconvenient for production implementation. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a tire carving support device, which can conveniently fix the tire with the rim from the ground to the bracket for carving.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a supporting device for tire carving is provided with a load-bearing base, a vertical lifting frame is fixed on the load-bearing base, a motor box which can be lifted and locked is installed on the vertical lifting frame, and the characteristic is that a motor is installed in the motor box, a rotating shaft is mounted on the transmission shaft of the motor, a drum brake is mounted on the end of the rotating shaft close to one side of the motor, the drum brake is fixed on the motor box, the inner cavity of the drum brake is a circular structure, a hinge piece is provided in the inner cavity of the drum brake, one end of the left brake pad and the right brake pad are hinged on the hinge piece through a fixed shaft, a spring is connected between the left brake pad and the right brake pad, the other end of the left brake pad and the right brake pad are hinged to the two ends of the hydraulic pump, an upper support rod is connected between the hydraulic pump and the transmission shaft, a lower support rod is connected between the hinge piece and the transmission shaft, the other end of the rotating shaft is fixed to the end of the transmission shaft through a gear plate and a gear plate fixing screw group, a circular wheel rim fixing plate is installed on the rotating shaft, and a threaded hole is processed on the wheel rim fixing plate.

[0006] The utility model has the beneficial effects that, before carving a smooth tire, the tire with the rim can be conveniently fixed on a bracket from the ground; when carving the smooth tire, the tire with the rim can be effectively lifted and rotated to a position suitable for carving, and the tire can be prevented from rotating when the knife is cut; after carving the smooth tire, the tire with the rim can be conveniently placed on the ground and removed.

DETAILED DESCRIPTION

[0014] In the figure, the utility model is provided with a load-bearing base 1, a vertical lifting frame 2 is fixed on the load-bearing base 1, a motor box 3 and a control panel 4 that can be lifted and locked are installed on the vertical lifting frame 2, the motor box 3 and the vertical lifting frame 2 can be lifted and lowered by adopting the matching relationship of gears and racks, a motor is installed in the motor box 3, a rotating shaft 6 is mounted on the transmission shaft 7 of the motor, a drum brake 5 is mounted on the end of the rotating shaft 6 close to the motor side, the drum brake 5 is fixed on the motor box 3, the inner cavity of the drum brake 5 is a circular structure, the inner cavity of the drum brake 5 is provided with a hinged piece 5F, a left brake pad 5BL, a right brake pad 5BL, a right brake pad 5BL, a left ... One end of the wheel plate 5BR is hinged to the hinge plate 5F via a fixed shaft, a spring 5E is connected between the left brake pad 5BL and the right brake pad 5BR, the other ends of the left brake pad 5BL and the right brake pad 5BR are hinged to the two ends of the hydraulic pump 5A, an upper support rod 5C is connected between the hydraulic pump 5A and the transmission shaft 7, a lower support rod 5D is connected between the hinge plate 5F and the transmission shaft 7, the other end of the rotating shaft 6 is fixed to the end of the transmission shaft 7 via a gear plate 7A and a gear plate fixing screw group 7B, a circular rim fixing plate 9 is installed on the rotating shaft 6, and a threaded hole is machined on the rim fixing plate 9.

[0015] When the utility model is used, the rocker on the control panel 4 is operated to lower the motor box 3 to a height convenient for installing the tire, the tire and the rim 8 are installed on the rotating shaft 6, and the rim fixing screw group 6A is screwed into the threaded hole of the rim fixing plate 9 to fix the tire and the rim 8 together with the rotating shaft 6, and the tire is left to stand to balance the air pressure in the tire. When carving the tire, the locking button below the rocker on the control panel 4 is pressed to push the hydraulic pump 5A on the drum brake 5 to the left and right, pushing the left brake pad 5BL and the right brake pad 5BR to rotate outward around the fixed axis on the hinge plate 5F, and then fully rubbing with the inner side of the disc of the drum brake 5 behind the rotating shaft 6, so that when the carving knife cuts into the tire, the tire can be kept stationary and does not rotate. When carving the next part of the pattern, press the lock button on the control panel 4 again to release the hydraulic pump 5A, and the spring 5E pulls the left brake pad 5BL and the right brake pad 5BR back to their original positions. Operate the rocker on the control panel 4, and the motor drives the front end of the transmission shaft 7 to rotate. The front end of the transmission shaft 7 is connected to the rotating shaft 6 through the gear plate 7A, and then drives the tire and rim 8 fixed on the rotating shaft 6 to rotate to the next carving position. After the overall carving is completed, operate the rocker on the control panel 4 to lower the motor box 3, so that the tire and rim 8 fall to the ground, which is convenient for overall removal.
