As shown in fig. 1 and 2, the rim finishing device includes a support base 10 and a finishing unit, wherein the finishing unit includes two finishing mechanisms 20, the two finishing mechanisms 20 are oppositely disposed on the support base 10 and are adjustable in position relative to the support base 10, each finishing mechanism 20 has a rolled end surface, and the two rolled end surfaces of the finishing unit are respectively used for rolling or grinding the circumferential edges of the two axial sides of the rim 1.

The application provides a rim finish machining device, ensures that the peripherys of the axial both sides of rim 1 are rolled or are polished and reach ideal default.

Specifically, the finishing unit of the rim finishing device comprises two finishing mechanisms 20, each finishing mechanism 20 is provided with a rolled end face, and the positions of the two finishing mechanisms 20 relative to the support base 10 are adjustable, so that after the rim 1 is installed at the preset processing position, the two finishing mechanisms 20 move towards the direction close to the rim 1, the two rolled end faces of the finishing unit are in contact with the circumferential edges of the two axial sides of the rim 1, the circumferential edges of the two axial sides of the rim 1 are rolled or ground to be smooth in a rotating mode, and the circumferential edges of the two axial sides of the rim 1 are ensured to form smooth transition faces after being rolled or ground.

The rim finish machining device provided by the application can be used for processing the peripheral edges of two axial sides of the rim 1 to be smooth in a mode of simultaneously rolling or polishing two rolling end surfaces, so that the smoothness of the curved surface of the smooth transition surface is ensured, and the peripheral edges of the two axial sides of the rim 1 can meet preset requirements; in addition, the tire scratch caused by burrs at the peripheries of the two axial sides of the rim 1 is avoided, and the practicability of the rim 1 is effectively improved.

As shown in fig. 2, the finishing mechanism 20 includes a mounting arm 21 and a binding wheel assembly 22, wherein a first end of the mounting arm 21 is hinged to the support base 10; the binding wheel assembly 22 includes a mounting base 221, a binding wheel 222 and a first driving portion 223, wherein the mounting base 221 is connected with the mounting arm 21, the binding wheel 222 is rotatably disposed at one end of the mounting base 221, an outer circumferential surface of the binding wheel 222 is a rolling end surface, and the first driving portion 223 is disposed at one end of the mounting base 221 far away from the binding wheel 222 and is in driving connection with the binding wheel 222. In this way, before finishing the peripheral edge of the rim 1, an operator can adjust the rotation angle of the mounting arms 21 to enable the space enclosed between the two mounting arms 21 to be matched with rims 1 of different models, so as to ensure that the rim finishing device can finish the peripheral edge of the rims 1 of different models; in addition, the installation stability of the finishing mechanism 20 is ensured by the installation of the installation base 221, and because the rolling wheel 222 is rotatably arranged at one end of the installation base 221, when the rolling wheel 222 rotates, two rolling end surfaces of the finishing unit simultaneously roll or grind the circumferential edges at two axial sides of the rim 1, so that the circumferential edges at two axial sides of the rim 1 are ensured to be processed smoothly at the same time, and the finishing efficiency of the rim 1 is improved; and the first driving part 223 can provide power for the binding wheel 222 to rotate, ensuring that the binding wheel 222 can stably and reliably rotate.

As shown in fig. 3, the roll-off end face is formed with a roll-off ring groove 100 into which the peripheral edge of the rim 1 protrudes. In this way, the rolling ring groove 100 has a stop limiting effect on the peripheral edge of the rim 1, and in the rotating process of the rolling wheel 222, the peripheral edge of the rim 1 is ensured to be always positioned in the rolling ring groove 100, so that the finish machining reliability of the rim finish machining device is ensured.

Thus, after the position of one rolling ring groove 100 on the rolling end surface of the rolling wheel 222 is seriously worn, the periphery of the rim 1 can be extended into the other rolling ring groove 100 on the rolling end surface of the rolling wheel 222, and the problem that the position of the rolling ring groove 100 of the rolling wheel 222 cannot play a role in stably and reliably stopping and limiting the periphery of the rim 1 due to serious wear is avoided.

Alternatively, the groove wall surface of the rolling ring groove 100 is a smooth curved surface. Thus, the groove wall surface of the roll annular groove 100 of the hemming wheel 222 is in rolling contact with the circumferential edge of the rim 1, and the hemming wheel 222 is ensured to roll the circumferential edge of the rim 1 into a smooth curved surface adapted to the groove wall surface of the roll annular groove 100.

Of course, the wall surface of the roll ring groove 100 is a rough surface having a predetermined surface roughness, so that the rim 1 can be finely ground by controlling the rotation speed of the rolling wheel 222, and the desired rim 1 can be obtained.

It should be noted that, in the present application, in order to ensure that the circumferential edge of the rim 1 can fully extend into the roll ring groove 100 on the roll end face, as shown in fig. 2, the binding wheel assembly 22 is connected with the mounting arm 21 in a position-adjustable manner, and the binding wheel assembly 22 has an escape position and a working position on the path of the position adjustment, and when the binding wheel assembly 22 is in the working position, the axis of the binding wheel 222 forms an assembly angle C with the axis of the rim 1.

Alternatively, there are two support wheels 30, two support wheels 30 are used to support the rim 1, and the two support wheels 30 are disposed at intervals along the axial direction of the rim 1 on both sides of the support base 10.

As shown in fig. 1, the rim finishing apparatus further includes a stopper mechanism 40, the stopper mechanism 40 includes a plurality of support guide wheels 41, the support guide wheels 41 are rotatably provided and adapted to abut against the outer peripheral surface of the rim 1, and the plurality of support guide wheels 41 are provided at intervals in the circumferential direction of the rim 1.
