The operation principle of the present invention：
1st, automatic tire-mounting：Automatic tire-mounting pattern is selected, the positional parameter related to setting is adjusted, will need to fill the steel ring of tire
It is placed on rotating disk 31, the tire on the drive wheels fixed claw 32 of fixed claw hydraulic means 34 clamps steel ring；Tire to be assembled is placed on
On steel ring, full-automatic dress tire operation button is pressed, presser feet 521, which declines, props up tire on one side, and rotating disk 31 rotates, while travelling carriage 7
Decline, tyre press wheel 41 pushes down tire another side, the upward spraying lubricant of gimbaled nozzle 821 to tire and steel ring contact site, with
Rotating a circle for rotating disk 31, steel ring is inserted in the lower surface of tire by tyre press wheel 41；Presser feet 521 leaves automatically, tyre press wheel 41 with
Tire, which declines to continue to decline, to be kept to tire pressure, and after rotating disk 31 rotates a circle again, steel ring is also inserted in tire upper surface；Complete
Fill after tire, the tire on the drive wheels fixing device 3 of rotating disk hydraulic means 35 is turned to unclamps with plane perpendicular position, tire fixed claw 32,
Workman removes tire.
2nd, tire is torn open automatically：It is rotational automatic to tear loose tool formula open, the positional parameter related to setting is adjusted, will prepare to dismantle after deflation
Tire be rolled at the rotating disk with bottom surface vertical position, tire is directed at tire fixed claw 32, press and tear tire operation button open automatically,
The clamping tyre rim of 34 tire on the drive wheels fixed claw of fixed claw hydraulic means 32, the tire on the drive wheels fixing device 3 of rotating disk hydraulic means 35
Horizontal level is rotated back to, rotating disk 31 rotates, tyre press wheel 41 declines extruding tire upper surface automatically, make tire top and steel ring pine
Relax；The tilt rotation certain angle of fixing device of the tire 3 is stepped down, and tyre press wheel 41 is dropped under tire, the return water of fixing device of the tire 3
Flat, tyre press wheel 41 makes tire bottom be relaxed with steel ring from the upward tire lower surface in tire bottom；Tear open tire hook 62 decline and with
Certain angle inserts tire and steel ring intersection, tears tire open and hooks 62 and turn an angle and rise one jiao of pull-up tire and goes out steel ring, together
When the first sprinkling through hole 811 and second spray the spraying lubricant of through hole 812 to tire upper surface and steel ring contact site；Rotating disk 31
Rotate a circle, tear tire open and hook 62 by tire upper surface and steel ring disengaging；Now, tyre press wheel 41 rises, and is squeezed upwardly from tire lower end
Pinch roller tire, the upward spraying lubricant of gimbaled nozzle 821 to tire and steel ring contact site after rotating disk 31 rotates a circle again, presses tire
Wheel 41 departs from tire lower surface and steel ring, and so far, tire is completely disengaged from steel ring.
3rd, when using filling tire manually or tearing tire open, the manual mode of control device is pressed, then tire changer enters manual
Pattern, the first pneumatic means 513 and the second pneumatic automatic deflation of assembling device 514, manual toggle auxiliary tyre pressing device to suitable position
Put, realize that each operation is manually operated by controlling switch.
