Description

Technical Field

[0001] The utility model relates to the technical field of balancing machines, and more specifically, to a tire clamping mechanism for a balancing machine. Background Art

[0002] With the increase in the number of cars, the use of tire dynamic balancing machines is becoming more and more widespread. Dynamic balancing is required when replacing new tires or after tire disassembly and assembly. After the tire is installed on the rim, it is usually impossible to distribute the weight 100% evenly. A balancing machine is used to test the balance of the tire rim in motion, and a balancing block is used to counterweight the unbalanced point to ensure that the tire can run smoothly and avoid shaking. During the tire dynamic balancing operation, the tire needs to be installed on the balance shaft for high-speed rotation. Since high-speed rotation will generate a large centrifugal force, the clamping device of the balancing machine is very important. Although the clamping device of the existing balancing machine has tools such as quick nuts, the nuts still need to be tightened with force, which is inconvenient to install and disassemble, reducing work efficiency. For this reason, we have designed a balancing machine spring clamping device. Utility Model Content

Under the action of the motor 3, the first threaded rod 4, the threaded cap 8, the telescopic frame 9 and the card plate 12, it is more convenient for people to clamp the tire.

[0029] Specifically, there are four telescopic frames 9, and they are symmetrically and movably connected to the surface of the threaded cap 8 in pairs. A movable groove is opened on the surface of the chassis 2, and there are four movable grooves in total, and they are symmetrically opened on the surface of the chassis 2 in pairs.

Then people control the motor 3 to operate through the control switch. The operation of the motor 3 drives the first threaded rod 4 and the second threaded rod 5 to rotate, and at the same time drives the threaded cap 8 and the telescopic frame 9 to operate, so that the card plate 12 expands outward, and then clamps and fixes the tire.
