Tyre clamping mechanism for vehicle production line

The invention discloses a tyre clamping mechanism for a vehicle production line, and belongs to the field of vehicle assembling workshop mechanized transportation. The tyre clamping mechanism comprises a base, wherein a driving device is fixedly connected to the base; a clamp holder is also hinged to the base; the driving device and the clamp holder are connected through a push-pull rod; the driving device, the clamp holder and the push-pull rod form a slider-crank mechanism. The tyre clamping mechanism is characterized in that a guiding wheel which is horizontally arranged is arranged at the bottom end of a supporting seat of a push rod of the driving device; a guiding plate which can be cooperated with the guiding wheel is arranged on the base; the guiding wheel is tangent with the inner side wall of the guiding plate. According to the tyre clamping mechanism disclosed by the invention, the structure is simple, the clamp holder is driven by the driving device in the horizontal direction, so that a vehicle front wheel can be stably clamped, and the accurate clamping and positioning of a vehicle in a service position of an automatic production line is realized safely and efficiently.
