Abstract

The utility model discloses a top-speed disassembling and assembling head for a tire disassembling and assembling machine, and belongs to the technical field of design and manufacture of the top-speed disassembling and assembling heads for the tire disassembling and assembling machines. The top-speed disassembling and assembling head comprises a steam cylinder and a hexagonal sliding rod, wherein the lower part of a piston rod is provided with a hook seat; and a hook head is arranged on a hook-head coupling pin. The hook seat is internally provided with a nylon cushion block; a tire-assembling pulley seat is provided with a tire-assembling pulley. When the top-speed disassembling and assembling head works, a rim is fixed by clamping blocks on a working platform. The steam cylinder is started, the piston rod drives the hook seat and the hook head to extend into gaps between the tire and the rim downwards, then the hook head is lifted upwards, the working platform is rotated by 360 degrees, and the tire is disassembled. When the tire is assembled, a working arm is rotated to the tire-assembling position, then the tire leans against the tire-assembling pulley, the working platform is rotated, and the bead of the tire is embedded into a rim clamping edge under the attachment of the tire-assembling pulley so as to finish the tire-assembling action. The top-speed disassembling and assembling head disclosed by the utility model has the advantages that the structure is simple and the design is ingenious; due to the hook head, the tire-assembling pulley and the nylon cushion block, the tire-disassembling and tire-assembling operation becomes very simple and fast without using auxiliary tools such as a crowbar, no damage caused to the tire and the rim in operation is ensured, and the problems in the traditional equipment are solved.

Description

The extremely fast dismounting head of tyre removing and replacing machine

Technical field

The utility model belongs to the design and the manufacturing technology field of tyre removing and replacing machine dismounting head.

Background technology

The tyre removing and replacing machine that in production reality, uses at present, its dismounting head has several types, and though the degree of automation that has is higher, its structure is also very complicated, needs to be equipped with air pressure and two kinds of propulsions source of hydraulic pressure, and manufacturing cost is high, and maintenance rate is high.The structure that has is comparatively simple, but owing to the action of the reason dismounting on the structure design is not really flexible, influences operation progress and efficient, is used for protecting the injury-free nylon protection pad abrasion factor of tire very high in addition, need often change.Be exactly traditional dismounting head in addition, need have crowbar to be used during operation, and crowbar is easy to tyre and rim is caused damage in the operation, and increase labor intensity of operating personnel.Work efficiency is low naturally.

Summary of the invention

To above-mentioned situation, the purpose of the utility model provides a kind of easy to operate, and need not accessory the tyre removing and replacing machine dismounting head of operation.To solve the problem that existing product exists.

The novel technical scheme of being taked for solution existing product existing problems of this use is: be made up of cylinder and six side's slide bars, a connecting plate is arranged at the top of cylinder, have six side's slide bars on the connecting plate.Have a hook seat in the bottom of piston rod, one gib head set bar is arranged, on the gib head set bar, have gib head in the piston rod bottom.In the bottom of gib head set bar one pull bar set pin is arranged, on the pull bar set pin, have pull bar.On gib head, have the pull bar set bar.One client link of pull bar is on the pull bar set bar.In the hook seat, have the nylon cushion block.Tire pulley base on one is arranged on the outside of hook seat, on last tire pulley base, have the tire pulley.On cylinder, have pneumatic valve.The utility model is mounted on the working arm of tyre removing and replacing machine and works.As will carry out remove a tyre the time, tire is placed on the bench board, by the fixture block on the bench board wheel rim is fixed.Start cylinder then and make under the piston rod and to move, drive hook seat and gib head, under the support of connecting rod, do movement in a curve downwards and stretch in tire and the wheel rim slit, will start cylinder again, make on the gib head and carry, with the tire beads pull-up, disengaging wheel rim edge.Then bench board is revolved three-sixth turn, pull down tire is suitable for reading.Again gib head is stretched into the tire end opening, repeat above-mentioned action, the tire end opening is pulled down.When mount tyre, tire is positioned over the wheel rim top, the rotary work arm is in the fetal position; Clickwise bench board to tire lip leans on the tire pulley, then rotary table again; Under the reclining of last tire pulley, tire beads is inlaid in the wheel rim edge, movement of the foetus is done in the completion.This use new structure is simple, designs ingenious.Owing to have gib head and last tire pulley and a nylon cushion block, make and tear tire and the operation of the last tire very simple and fast that becomes open, need not use accessory appliancess such as crowbar, and guarantee can not cause damage in operation tyre and rim.Because simple in structure, both reduced manufacturing cost, also reduced fault rate.Also alleviated labor intensity of operating personnel.The problems that existing installation exists have been solved.
