Description

Technical Field

[0001] This utility model relates to the field of tire changing machines, and more particularly to a tire changing machine with synchronous telescopic extension. Background Technology

[0002] With the rapid development of my country's automobile industry, the number of cars on the road is increasing year by year, and maintenance and repair services are receiving more and more attention. In the wheel maintenance industry, tire changers are the mainstream, labor-saving, and quick tire removal and installation equipment.

[0003] However, existing tire changers are complex to operate and have poor synchronization during tire removal and installation. Tire lifting and pressing need to be done separately and aligned separately, resulting in low efficiency. Utility Model Content

[0004] This invention provides a synchronously telescopic tire changing machine to overcome the above-mentioned problems.

[0005] A synchronous telescopic tire changer includes: a housing, a first column, a tire pressing part, a tire supporting part, and a drive part;

[0006] The first column is fixedly mounted on the box body, and the driving part is provided on the top of the first column;

[0007] The tire pressing part includes a tire pressing trolley that can slide up and down along the first column, a tire pressing shaft that can move in the tire pressing trolley in a direction perpendicular to the first column, and a tire pressing wheel provided at the end of the tire pressing shaft. The tire supporting part includes a tire supporting trolley that can slide up and down along the first column, a tire supporting shaft that can move in the tire supporting trolley in a direction perpendicular to the first column, and a tire supporting wheel provided at the end of the tire supporting shaft.

[0008] The power output end of the drive unit is provided with a rack, and the drive unit can drive the rack to reciprocate. The housing is rotatably provided with a transmission shaft, and the rack meshes with a first gear fixed at one end of the transmission shaft. A second gear and a third gear are also coaxially provided on the transmission shaft. The tire pressure shaft and the tire support shaft are both provided with meshing teeth. The tire pressure shaft meshes with the second gear, and the tire support shaft meshes with the third gear.

[0009] Furthermore, the driving unit is a driving cylinder, and the rack is fixedly connected to the piston rod of the driving cylinder.

[0010] Furthermore, a column top plate is fixed to the top of the first column, and the transmission shaft is disposed between the column top plate and the box body via a bearing;

[0011] The drive unit is fixed to the upper plate of the column.

[0012] Furthermore, the box body is also provided with a second column, on which a tire pressing arm is mounted, and a tire pressing block is provided at the end of the tire pressing arm.

[0013] Furthermore, the side of the box is equipped with a tire-removing shovel and a tire support frame.

[0014] Furthermore, the housing is equipped with a tire-pressing cylinder, the cylinder body of which is hinged to the housing, and the piston rod of which is hinged to the tire-pressing trolley.

[0015] Furthermore, the tire-supporting trolley is a hollow structural component and is sleeved outside the first column. Two upright plates are fixed to the outer side of the tire-supporting trolley. Each upright plate has a through hole, and a hexagonal sleeve is installed within each through hole. The hexagonal sleeve passes through the through holes of the two upright plates, and the tire-supporting shaft is installed within the hexagonal sleeve. The hexagonal sleeve has a slot located between the two upright plates, and the meshing teeth of the second gear and the tire-supporting shaft mesh at the slot.

[0016] Furthermore, a gear guard plate is provided on the outer side of the third gear, and the gear guard plate is fixedly connected to the hexagonal sleeve.

[0017] The synchronous telescopic tire changing machine disclosed in this utility model drives the rack to move linearly through the drive unit. The rack drives the transmission shaft to rotate through the first gear. The transmission shaft drives the tire support shaft and the tire pressure shaft to move linearly synchronously through the second gear and the third gear. This solves the problem of adjusting the tire support shaft and the tire pressure shaft separately, improves work efficiency, and ensures the synchronicity of the positions of the tire support wheel and the tire pressure wheel.

[0018] During tire installation and removal, the tire is on a turntable with the tire support roller underneath. Confirming the position of the tire support roller usually requires bending over, which is inconvenient and inefficient. This invention discloses a synchronously telescopic tire changer where the pressure roller and tire support roller move synchronously and are positioned accordingly. During operation, the position of the tire support roller can be determined by observing the position of the pressure roller, eliminating the need to bend over. This reduces the operator's workload, lightens the operational burden, and improves operational accuracy and work efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The drive unit 20 has a rack 10 at its power output end, which drives the rack 10 to reciprocate. The housing 1 has a rotatable transmission shaft 11, and the rack 10 meshes with a first gear 12 fixed at one end of the transmission shaft 11. A second gear 13 and a third gear 14 are also coaxially mounted on the transmission shaft 11. The tire pressure shaft 5 and the tire support shaft 8 are both equipped with meshing teeth.
