DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-7 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Reference Figure 1-Figure 4 A rim edge grinding rotary tooling includes a frame 1, a rotary device 2 and a lifting device 3. A panel 4 is fixedly arranged horizontally on the frame 1, and a rotary groove 41 is opened at the center position of the surface of the panel 4, wherein the rotary device 2 includes a first power assembly 21, a first roller 22 and a second roller 23. The first roller 22 and the second roller 23 are respectively rotatably connected and installed on the frame 1, and the first roller 22 and the second roller 23 are kept in a horizontal state and are respectively located on both sides of the rotary groove 41 for supporting the rim. The first power assembly 21 is set as a variable frequency reduction motor, and a driving sprocket 211 is fixedly arranged on the rotating shaft of the variable frequency reduction motor. Correspondingly, a driven sprocket 221 is fixedly arranged on the first roller 22, so that the driven sprocket 221 and the driving sprocket 211 are on the same vertical plane, and the driving sprocket 211 and the driven sprocket 221 are connected through a first chain 24 to achieve transmission connection. The rotating shaft of the variable frequency reduction motor rotates to drive the driving sprocket 211 to rotate, and the driven sprocket 221 and the first roller 22 are rotated through the transmission of the first chain 24 .

[0030] In order to make the second roller 23 rotate synchronously with the first roller 22, a first transmission sprocket 222 is fixedly provided on the first roller 22, and a second transmission sprocket 231 is fixedly provided on the second roller 23 correspondingly, so that the second transmission sprocket 231 and the first transmission sprocket 222 are on the same vertical plane, and the first transmission sprocket 222 and the second transmission sprocket 231 are connected by a second chain 25. When the variable frequency reduction motor drives the first roller 22 to rotate, the second roller 23 is driven to rotate through the second chain 25.

[0031] The rim rolls from the assembly line into the revolving groove 41 and contacts the first roller 22 and the second roller 23 respectively. The variable frequency reduction motor starts to drive the first roller 22 and the second roller 23 to rotate, thereby driving the rim on the first roller 22 and the second roller 23 to rotate. When the first roller 22 and the second roller 23 are rotating, in order to improve the rotation efficiency of the rim, the first roller 22 and the second roller 23 are both set as rubber-coated rollers. The rubber coating of the rollers can effectively improve the operating conditions of the conveying system and protect the metal rollers from wear. At the same time, after the surfaces of the first roller 22 and the second roller 23 are set as rubber-coated rollers, there is greater friction between their surfaces and the rim to avoid slipping between the rim and the first roller 22 or the second roller 23.

[0032] Reference Figure 5-Figure 7 The lifting device 3 includes a second power assembly 31, a lifting plate 32, a fixed frame plate 33, a plurality of guide pillars 34 and a plurality of guide sleeves 35, wherein the second power assembly 31 is configured as a cylinder; the fixed frame plate 33 is fixedly arranged at the bottom end of the panel 4, and a through hole 331 is opened on the surface of the fixed frame plate 33. The cylinder is fixedly arranged at the bottom end of the fixed frame plate 33 and kept in a vertical state, so that the telescopic rod of the cylinder passes through the through hole 331 of the fixed plate frame, and the lifting plate 32 is horizontally arranged at the bottom end of the rotary groove 41 and fixed with the telescopic rod of the cylinder, and the lifting and lowering of the lifting plate 32 is driven by the telescopic movement of the telescopic rod of the cylinder. In order to ensure that the lifting plate 32 is lifted and lowered smoothly, a plurality of guide posts 34 are vertically fixed at the bottom of the lifting plate 32, and a plurality of guide sleeves 35 are arranged on the fixed frame plate 33, so that each guide post 34 is inserted into the guide sleeve 35. When the cylinder drives the lifting plate 32 to lift and lower, each guide post 34 is lifted and lowered and slid in the guide sleeve 35, so as to avoid position deviation of the lifting plate 32 during the lifting and lowering process. In order to ensure that each guide post 34 is lifted and lowered and slid in the guide sleeve 35 smoothly, an oil nozzle 351 is provided on the surface of each guide sleeve 35, so that lubricating oil can be regularly added into the guide sleeve 35 from the oil nozzle 351, so as to ensure lubrication of the guide post 34 and the guide sleeve 35 during operation.

[0033] In order to keep the lifting plate 32 in good balance, a floating joint 36 is provided between the cylinder and the lifting plate 32, and the two ends of the floating joint 36 are respectively fixed to the lifting plate 32 and the telescopic rod of the cylinder. The floating joint 36 can compensate for the vertical straightness error of 3 degrees and absorb the "eccentric" parallelism deficiency between the lifting plate 32 and the cylinder, so as to ensure the smooth operation of the lifting plate 32. The cylinder is guaranteed to work effectively for a long time to extend the service life of the cylinder. In addition, when the rim is rotated by the rotary fixture, in order to make the panel 4 on the rotary fixture consistent with the position height of the assembly line, a number of foot cups 11 are threadedly installed on the bottom end of the frame 1, so that the position height of the top panel 4 of the frame 1 can be adjusted by the number of foot cups 11, so that the panel 4 of the rotary fixture can adapt to the assembly lines with different position heights.

[0034] The specific implementation principle of the embodiment of the present application is as follows: when the rim needs to be rotated using the rotary tooling to grind the edge of the rim, the foot cup 11 at the bottom of the frame 1 is adjusted so that the panel 4 on the frame 1 is flush with the horizontal position height of the assembly line. The rim then rolls from the assembly line into the rotary groove 41 provided in the panel 4, so that the bottom end of the rim abuts against the first roller 22 and the second roller 23, and then the shaft of the variable frequency reduction motor rotates to drive the active sprocket 211 to rotate, thereby driving the first roller 22 to rotate through the first chain 24, and at the same time driving the second roller 23 to rotate. During the rotation of the first roller 22 and the second roller 23, the friction between them and the rim is used to drive the rim to rotate, so that the handheld angle grinder can grind the edge of the rim. After the grinding is completed, the telescopic rod of the cylinder is extended to drive the lifting plate 32 to rise and abut against the bottom end of the rim until the lifting plate 32 rises to be flush with the surface of the panel 4, so that the rim can be rolled along the surface of the panel 4 to the next process.

[0035] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all protected by the utility model.
