Tension mechanical arm tire polishing device

Abstract

The invention discloses a tension mechanical arm tire polishing device which comprises a rotary boss and two tension mechanical arms symmetrically arranged on the two sides of the rotary boss. Each tension mechanical arm comprises a sanding roller and two tensioners arranged at the upper end and the lower end of the sanding roller correspondingly; each tensioner comprises two torsional springs symmetrically arranged on a frame body; each torsional spring is connected with the first end of a torsion beam; the second end of each torsion beam is hinged to one end of a grinding arm; and the other ends of the two grinding arms are hinged together through the corresponding sanding roller. Twisting force is applied through the torsional springs, the sanding rollers can be attached to the side face of a tire with certain tension, the effect that the sanding roller is in close contact with the side face of the tire all the time is guaranteed, and even if the tire or equipment shakes, the sanding roller can conduct polishing operation. The two tensioners apply tension to the upper end and the lower end of the sanding roller correspondingly, the sanding roller can be stably attached to the surface of the tire in the vertical direction, the effect that the upper end and the lower end of the sanding roller are attached to the surface of the tire with uniform tension all the time is guaranteed, and the polishing effect us more uniform.

Description

technical field [0001] The invention relates to tire grinding equipment, in particular to a tension manipulator tire grinding device. Background technique [0002] During the tire grinding process, two situations are involved. One is tire retreading, by grinding the tire surface clean, removing oil stains, damaged parts, etc.; the other is grinding some corners and excess parts of new tires, and grinding the new stubble after cutting. The situation that can be encountered in the above-mentioned process is: the tire is fixed or positioned near the emery wheel, preferably after the tire is fixed, the tire can be rotated along its axis so as to polish the circumferential surface of the tire; when grinding the tire surface, the grinding tool It is difficult to effectively control the adhesion force on the surface of the tire. If it is too tight, the tire will be easily deflated and over-grinded. If it is too loose, the grinding effect will not be enough. A grinding equipment wi...

The situation that can be encountered in the above-mentioned process is: the tire is fixed or positioned near the emery wheel, preferably after the tire is fixed, the tire can be rotated along its axis so as to polish the circumferential surface of the tire; when grinding the tire surface, the grinding tool It is difficult to effectively control the adhesion force on the surface of the tire. If it is too tight, the tire will be easily deflated and over-grinded. If it is too loose, the grinding effect of the tire is not enough. A grinding equipment with stable tension is needed.
