Vulcanizing machine tire gripper

Abstract

The invention discloses a novel tire grabbing device for a vulcanizing machine. The novel tire grabbing device comprises a rotary disc, a fixed disc, a rotary disc driving device and claw piece mechanisms, wherein the rotary disc and the fixed disc are coaxial, and the claw piece mechanisms are radially expanded and contracted on the fixed disc under driving of the rotary disc. The rotary disc driving device comprises a servo motor and a gear transmission pair with at least one level of deceleration transmission. A driving small gear of the gear transmission pair is connected with an output shaft of the servo motor through a connecting shaft. A driven large gear of the gear transmission pair is fixedly connected with the rotary disc. The driving small gear is further coaxially provided with a rotary encoder for controlling the expansion and contraction ranges of the claw piece mechanisms. According to the novel tire grabbing device for the vulcanizing machine, the opening and closing ranges of the claw piece mechanisms can be rapidly and accurately adjusted; manual adjustment is not needed; the working efficiency of the vulcanizing machine is improved; the equipment using cost is reduced; and the working safety is improved.

Description

technical field [0001] The invention relates to a component structure of a tire vulcanizing machine, in particular to a tire gripper for a vulcanizing machine. Background technique [0002] Customers require that one vulcanizing machine can vulcanize tires of various specifications, especially large-scale vulcanizing machines require more vulcanized tire specifications, that is, the manipulators of each vulcanizing machine can also require more tire specifications. [0003] At present, the opening and closing of the mechanical hand tire gripping mechanism is controlled by the cylinder. The cylinder stroke can only grab one or two specifications of tires. If you want to grab more specifications of tires, you need to manually adjust the range of the tire gripper, and you need to adjust it multiple times. The adjustment is difficult, time-consuming and laborious, which seriously affects the production efficiency; if the air source is closed or the air pipe leaks when the cylind...

[0003] At present, the opening and closing of the mechanical hand tire gripping mechanism is controlled by the cylinder. The cylinder stroke can only grab one or two specifications of tires. If you want to grab more specifications of tires, you need to manually adjust the range of the tire gripper, and you need to adjust it multiple times. Difficult to adjust, time-consuming and labor-intensive, seriously affecting production efficiency; if the air source is closed or the air pipe leaks when the cylinder controls the tire, it will cause the claw to shrink and the tire to fall, which will pose a safety hazard to the vulcanizing machine operator
