Description

Be used for tight pulley processingequipment that polishes that rises Technical Field The invention belongs to the technical field of grinding, and particularly relates to a grinding device for a tension roller. Background The automobile tension wheel is a device for tensioning a belt in an automobile transmission system, and can automatically adjust the tensioning force according to different tightness degrees of the belt, so that the transmission system can be ensured to stably, safely and reliably run. In the production and transportation links of the automobile tension wheel, extremely slight scratches, burrs or oxide layers can appear on the wheel surface. Wherein, the scratch can cause local stress concentration of the belt, accelerate belt abrasion, and even lead the belt to break when serious; the burrs may scratch the surface of the belt, causing damage to the belt. Therefore, it is necessary to polish the tread of the tensioner. During specific polishing operation, two sides of the tensioning wheel are required to be clamped by means of the clamping mechanism. In order to uniformly polish the whole circumferential surface of the tension roller, the clamping mechanism is required to rotate so as to drive the tension roller to rotate. However, in practical operation, when the clamping mechanism clamps the tensioner, it is difficult to accurately clamp the center of the tensioner, which results in eccentric rotation of the tensioner during rotation. Eccentric rotation can make the contact force of tight pulley and abrasive band uneven, and partial region is tighter with abrasive band contact, and another partial region is looser with abrasive band contact, finally causes the dynamics of polishing uneven, influences the effect of polishing. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide a polishing device for a tensioning wheel, which solves the technical problems that when a clamping mechanism clamps the tensioning wheel, the center of the clamping mechanism is difficult to clamp accurately, so that the tensioning wheel can eccentrically rotate in the rotating process, the eccentric rotation can cause uneven contact force between the tensioning wheel and an abrasive belt, partial area is tightly contacted with the abrasive belt, and the other partial area is loose contacted with the abrasive belt, so that uneven polishing force is caused, and the polishing effect is affected. In order to achieve the aim of the invention, the technical scheme adopted by the invention comprises a grinding device for a tension roller, which comprises the following components: A bracket; A sanding assembly disposed on the support; A first drive assembly for driving operation of the sanding assembly; The first clamping part is movably connected to the bracket, is positioned below the frosting component and can rotate relative to the bracket; The second clamping part is positioned below the frosting component and comprises a propping part and a centering cone, wherein the propping part is movably connected to the bracket, the propping part can rotate relative to the bracket, the centering cone is arranged at one end of the propping part relative to the first clamping part, the centering cone is of a conical structure, the small end of the centering cone faces the first clamping part, and the axis of the centering cone, the rotation axis of the propping part and the rotation axis of the first clamping part are consistent; The second driving assembly is used for driving the first clamping part and/or the second clamping part to move along the first horizontal direction so that the first clamping part and the second clamping part have a first stage of being close to each other and a second stage of being far away from each other, in the first stage, the centering cone penetrates into the center hole of the tensioning wheel to realize positioning, and in the process, the centering cone gradually supports the tensioning wheel so that the tensioning wheel is in contact with the sanding assembly. Compared with the prior art, the invention has the advantages that: (1) According to the polishing processing device for the tension roller, in the first stage, the first clamping part and the second clamping part are mutually close, the centering cone penetrates into the center hole of the tension roller, and the tension roller can be pushed to be close to the center of the centering cone in the process of penetrating into the center hole of the tension roller through the conical design of the centering cone, so that the positioning of the tension roller is realized. And because the axis of the centering cone, the rotation axis of the abutting part and the rotation axis of the first clamping part are consistent, the abutting part drives the tension wheel to rotate without eccentric rotation, the contact force between the tension wheel and the abrasive belt is more uniform, the polishing for
