Profiling polisher for inner wall of annular tread

Abstract

The invention belongs to the technical field of tire maintenance and relates to a profiling polisher for the inner wall of an annular tread. The profiling polisher comprises a base, wherein two rollers are supported on the base through two supports, one roller is driven to rotate by a first motor or a first pneumatic motor, an annular rotary cylinder is supported on the two rollers, an upper arm of an L-shaped support fixed on the base extends into the annular rotary cylinder, a supporting frame is fixed on the upper arm, a sliding block is glidingly arranged on a transverse sliding rail of the supporting frame, a sleeve is nested on a vertical shaft fixed on the sliding block, a mounting plate and a cantilever are fixed on the sleeve, a transverse shaft is rotationally arranged at the outer end of the cantilever, a polishing wheel is mounted at one end of the transverse shaft, and a second motor or a second pneumatic motor is mounted on the mounting plate and drives the transverse shaft to rotate through a drive device. The polisher has the advantages that the whole polishing surface has an appropriate arc through rotation of the cantilever, the labor intensity is low, the production efficiency is high, the polishing quality is good, little harm is caused to human bodies, and the polisher is suitable for automatic polishing of the inner wall of the annular tread.

Description

technical field [0001] The invention belongs to the technical field of tire retreading, in particular to a profiling grinding machine for the inner wall of an annular tread. Background technique [0002] At present, when retreading damaged tires, it is necessary to grind the inner wall of the annular tread. When grinding, the inner wall of the tire is generally ground with a hand grinder or a grinder. The disadvantage is that the equipment for grinding the inner wall of the tire requires manual labor Hand-held, one is that the ground rubber broken pins or rubber particles seriously pollute the air, and the operator will cause damage to the operator if he gets close to this area; the other is that the equipment for manually grinding the inner wall of the tire causes high labor intensity for the operator; The efficiency is low; the fourth is that the thickness of the grinding is not uniform enough, and the radian of the grinding surface cannot be unified, which affects the qua...
