DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] Reference Figure 1-6 As shown, a tire sidewall grinding device includes a grinding table body 1 and a tire 2. A limiting mechanism is provided on the top of the grinding table body 1 for positioning and clamping the tire 2. The tire 2 is vertically distributed on the grinding table body 1.

[0030] A first bracket 311 is fixed on the top of the grinding table body 1, and a hydraulic rod 312 is installed on the outer wall of the first bracket 311. The output end of the hydraulic rod 312 is rotatably connected to a connecting plate 313, and a driven gear 314 is fixed on the outer wall of the connecting plate 313. A grinding disc 315 corresponding to the tire 2 is fixed on the outer wall of the driven gear 314 away from the connecting plate 313. The grinding disc 315 can be a tungsten steel grinding disc, which is a super alloy grinding disc that can be used to grind various high-hardness materials, mainly used for roughening soft materials such as rubber and plastic. After the hydraulic rod 312 is turned on, the connecting plate 313, the driven gear 314 and the grinding disc 315 are driven to move toward the side of the tire 2, and the grinding disc 315 can fit with the outer wall of the tire 2. When the connecting plate 313 rotates, it drives the driven gear 314 and the grinding disc 315 to rotate, so that the grinding disc 315 and the outer wall of the tire 2 can be polished. A second bracket 316 is fixed to the top of the grinding table body 1, and a first motor 317 is installed on the outer wall of the second bracket 316. A rotating rod 318 is connected to the output end of the first motor 317. A driving gear 319 corresponding to the driven gear 314 is fixed to the side of the rotating rod 318 away from the second bracket 316. When the hydraulic rod 312 drives the connecting plate 313 and the driven gear 314 to move, it can mesh with the driving gear 319. After the first motor 317 is turned on, the rotating rod 318 and the driving gear 319 are driven to rotate. The driving gear 319 will mesh with the driven gear 314 and push the driven gear 314 and the grinding disc 315 to rotate, thereby achieving an automated grinding effect. This grinding method is more efficient and improves the comprehensiveness of the tire 2 grinding. When the hydraulic rod 312 drives the driven gear 314 to disengage from the driving gear 319, the staff can position and install the tire 2. A groove 421 is provided at the top of the grinding table body 1. The groove 421 is arc-shaped and matches with the driven gear 314. The provision of the groove 421 can ensure that the driven gear 314 can move back and forth easily.

[0031] The limiting mechanism includes a third bracket 412, a threaded sleeve 414, a connecting rod 415, a limiting ring 416, a hinged rod 417, a movable rod 418 and a driving assembly. The third bracket 412 is fixed to the top of the grinding table body 1. The limiting ring 416 is fixedly connected to the outer wall of the third bracket 412 through the connecting rod 415. The outer wall of the third bracket 412 is connected to a threaded sleeve 414 located in the middle position of the limiting ring 416 through a driving assembly. The outer wall of the threaded sleeve 414 is hinged with a movable rod 418 through a hinged rod 417. The movable rod 418 is slidably connected to the inner wall of the limiting ring 416. Under the action of the driving assembly, the threaded sleeve 414 is driven to move forward and backward, and the hinged rod 417 is driven to rotate, driving the movable rod 418 to retract and retract on the inner wall of the limiting ring 416, which can achieve the effect of resisting the inner wall of the tire 2, thereby limiting the rotation of the tire 2 and enhancing the grinding efficiency. A clamping plate 419 is fixed to one end of the movable rod 418 away from the hinge rod 417. The width of the clamping plate 419 is greater than that of the movable rod 418. The clamping plate 419 can increase the contact area with the inner wall of the tire 2 and can also ensure that the movable rod 418 will not separate from the inner wall of the limiting ring 416. Several groups of anti-skid pads 420 are fixed to one side of the clamping plate 419 away from the movable rod 418. The several groups of anti-skid pads 420 are made of rubber. The rubber material can increase the friction with the inner wall of the tire 2, further improve the stability of the tire 2, and prevent the tire 2 from falling off.

[0032] The driving assembly includes a second motor 411 and a threaded rod 413. The second motor 411 is installed on a side of the third bracket 412 away from the driven gear 314. The output end of the second motor 411 is connected to the threaded rod 413 threadedly connected to the threaded sleeve 414. After the second motor 411 is turned on, the threaded rod 413 is driven to rotate, and the threaded sleeve 414 is driven to move back and forth under the action of the thread, thereby achieving the purpose of automated driving.

[0033] Working principle: When grinding is required, the tire 2 is sleeved on the limiting ring 416, and then the second motor 411 is turned on to drive the threaded rod 413 to rotate. Under the action of the thread, the threaded sleeve 414 is driven to move away from the second motor 411, and the hinge rod 417 is driven to rotate, and the movable rod 418 is pushed out of the limiting ring 416. At this time, the anti-skid pad 420 can squeeze and fit the inner wall of the tire 2 to achieve the effect of preventing the tire 2 from falling off;

[0034] Subsequently, the hydraulic rod 312 is turned on to drive the connecting plate 313, the driven gear 314 and the grinding disc 315 to move toward the side of the tire 2, and the grinding disc 315 can fit with the outer wall of the tire 2, so that the driven gear 314 is meshed with the driving gear 319, and finally the first motor 317 is turned on to drive the rotating rod 318 and the driving gear 319 to rotate, and the driving gear 319 drives the driven gear 314 and the grinding disc 315 to rotate, and the grinding disc 315 can grind the side wall of the tire 2.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
