The invention relates to a tyre building device, in particular to a clamping device of a tyre building machine transfer ring. The clamping device comprises an upper plate, a middle plate, a lower plate, a servo motor, a transmission shaft, a lead screw and a clamping plate. The servo motor is installed on the upper plate. A bearing housing is arranged between the upper plate and the middle plate. The transmission shaft is arranged in the bearing housing. The upper end of the transmission shaft is in transmission connection with the servo motor through a gear and a synchronous belt. The middle of the transmission shaft is provided with a middle hole. A nut is fixedly arranged at the bottom of the middle hole. The lead screw is arranged in the center hole and is connected with the nut through a thread. The bottom of the lead screw is fixedly connected with the lower plate. A guide shaft is fixedly arranged on the lower plate. The middle plate is provided with a shaft sleeve. The guide shaft penetrates into the shaft sleeve. The clamping plate is fixedly arranged on the lower plate. The clamping portion of the clamping plate is an arc surface matched with a crown assembly in radian. By the adoption of the clamping device of the tyre building machine transfer ring, clamping block fixed-point quantitative control is achieved, and tyre dynamic balance is improved.
Description
technical field [0001] The invention relates to a tire building device, in particular to a clamping device for a transfer ring of a tire building machine. Background technique [0002] The crown assembly transfer ring of the molding machine is an important device for clamping and transferring the crown assembly compounded on the belt drum and combining it with the carcass assembly. Its clamping and positioning accuracy directly affect the tire uniformity and dynamic balance index. In actual production, the process requires that the combination accuracy between two circular components should be less than 0.3mm for circular jump and less than 0.3mm for end jump. [0003] The transfer ring of the molding machine currently used is a mechanical mechanism in which the piston rod of a cylinder drives the connecting rod to drive 11 clamping devices to move centripetally synchronously. Due to mechanical wear and tear, there are disadvantages such as poor synchronization of 11 clampi...
