In order to achieve the purpose, the one-time method mechanical drum of the small spare tire comprises a main shaft device and two side drum components which are symmetrical along the left and right structures of the main shaft device, wherein each side drum component comprises a side seat, a turning plate conical disc, a guide disc, a locking block air cylinder and a double-cone disc which are sequentially arranged, the side seats are parallel to the main shaft device, one side of the turning plate conical disc is in sliding contact with the side seats, the other side of the turning plate conical disc is in sliding contact with the guide disc and the double-cone disc, the double-cone disc is provided with a first inclined surface and a second inclined surface, the turning plate conical disc is in sliding contact with the first inclined surface, the locking block is in sliding contact with the second inclined surface, the guide disc is arranged between the locking block and the turning plate conical disc.
Preferably, the side drum member is capable of making a telescopic movement relative to the main shaft device.
Preferably, an included angle between the first inclined surface and the second inclined surface of the double-cone disc and the main shaft device is 10-80 degrees.
More preferably, the included angle degree of the first inclined surface of the double-cone disc is greater than that of the second inclined surface.
Preferably, the turnover plate conical disc is in at least 2 points of sliding contact with the side seat.
Preferably, the turnover plate cone disc is provided with a spring groove.
Preferably, the turning plate conical disc is provided with a positioning structure.
Preferably, the locking piece is provided with a locking structure.
The invention has the beneficial effects that:
(1) the invention improves the prior structure, drives the double conical disc through the locking block cylinder, and the double conical disc, the turning plate conical disc and the locking block are matched to do reciprocating motion relative to the main shaft device, thereby controlling the expansion and contraction of the mechanical drum, reducing one cylinder to enable the one-step mechanical drum steel ring locking structure position to be more compact, meeting the requirement of producing small spare tires, and particularly meeting the tire manufacturing with smaller width (the over-sizing width is 180 plus 220).
(2) The double-cone disc is provided with a first inclined surface and a second inclined surface, the turnover plate cone disc is in sliding contact with the first inclined surface, the locking block is in sliding contact with the second inclined surface, the included angle degree of the first inclined surface is larger than that of the second inclined surface, the turnover plate cone disc rises faster when the locking block props open and locks the steel ring, the steel ring is clamped to be positioned before the locking block is unlocked, and the position symmetry and the misalignment of the steel ring are guaranteed.
(3) The included angle between the first inclined plane and the second inclined plane of the double-cone disc and the main shaft device is 10-80 degrees. The ascending speed of the turnover plate conical disc and the locking block can be adjusted by controlling the change of the included angle between the first inclined plane and the second inclined plane of the double-conical disc and the main shaft, and the turnover plate conical disc can be ensured to ascend faster than the locking block.
(4) The sliding contact surface of the turnover plate conical disc and the side seat is provided with at least 2 contact points, so that the turnover plate conical disc is ensured to be corrected and not easy to deform under stress in the ascending process.
(5) The turnover plate conical disc is provided with the spring groove which can assist in retraction.
