Tire dismounting machine

Abstract

The invention relates to a tire dismounting machine. The tire dismounting machine comprises a base, a rack which is vertically fixed on the base, an auxiliary tire pressing device arranged at the upper end of the rack, a slide frame which slidingly sleeves the rack, a tire fixing device which is arranged on the base, and a tire pressing device and a tire dismounting device which are arranged on the slide frame in sequence from bottom to top, wherein the tire fixing device comprises a rotary table and tire fixing claws arranged on the upper end face of the rotary table; the tire fixing device is further provided with a fixing claw synchronizer; the fixing claw synchronizer comprises a synchronizing disc arranged in the middle of the rotary table and a plurality of linkage rods; one end of each of the plurality of linkage rods is hinged to the corresponding tire fixing claw and the other end of each of the plurality of linkage rods is hinged to the synchronizing disc at interval; and each linkage rod and the corresponding tire fixing claw are inclined to form a certain angle in the retracting direction of the tire fixing claw.

Description

technical field [0001] The invention relates to a tire changer and belongs to the field of automobile machinery. Background technique [0002] Tire changers are currently used to perform the disassembly and assembly operations between tires and their associated rims. After bead breaking, they can remove the tire from its rim, for example to perform maintenance or replacement work on the bladder, the rim and / or the tire itself, and then mount it or a new tire on the rim. Automobile tire dismantling machine has been generally used at present, generally includes base, frame, bead bead device, sliding frame, tire fixing device, bead bead device and tire dismantling device, prior art is used in a large number of manual operation, and manual operation not only labor High strength, low efficiency, and requires certain skills and a lot of experience, high labor requirements, long disassembly and assembly time, low degree of automation, it seems outdated in the current industry 4.0 ...

Problems solved by technology

Automobile tire dismantling machine has been generally used at present, generally includes base, frame, bead bead device, sliding frame, tire fixing device, bead bead device and tire dismantling device, prior art is used in a large number of manual operation, and manual operation not only labor High strength, low efficiency, and requires certain skills and a lot of experience, high labor requirements, long disassembly and assembly time, low degree of automation, it seems outdated in the current industry 4.0 era; the clamping device of the tire changer does not have a simple Synchronous device, the accuracy is not high, and it is easy to break down. The tire removal hook is generally fixed, and the tire needs to be pried up manually, which is very inconvenient. Moreover, the same tire changer cannot switch between manual and automatic, and it is difficult to take care of large quantities of tires of the same size. Removal and installation of individual tires of different sizes
