[0030] In some technical solutions, the side wall of the measuring frame 1 is equipped with a controller 11.

[0031] In this technical solution, controller 11 adopts an industrial-grade PLC controller (model Siemens S7-1200CPU1214C, supporting digital / analog input and output), paired with a 7-inch touch screen (resolution 800×480, capacitive touch, protection level IP65), installed in a waterproof distribution box (300mm×200mm×150mm, material ABS engineering plastic) on the side wall of measuring frame 1; the bottom of the distribution box has heat dissipation holes (5mm diameter, 20mm spacing, 20 holes), and an axial fan (2000r / min speed, 10CFM airflow) is installed inside to ensure that the controller's operating temperature is stable between 0-50℃, avoiding system crashes or data loss caused by high temperature.

[0032] Working principle: The operator places the wheel assembly 5 into the conveying chamber 12 of the conveyor frame 4 and starts the conveying process via the controller 11. The bearing in the conveying chamber drives the wheel to move. When the wheel reaches the work position between the upper and lower drive mechanisms, the photoelectric sensor (standard configuration) triggers a signal, the controller pauses the conveying, and the wheel is precisely positioned. Drive mechanism: The telescopic rod 23 under the fixed rod 22 extends with the elastic force of the support spring 24, driving the guide upper cone wheel 25 to contact the top of the tire tread. The telescopic rod can adapt to different wheel diameters, and the spring ensures contact and prevents slippage. Lower drive mechanism: The controller commands the electric push rod a6 to extend and retract, which pushes the telescopic rotating shaft 16 for fine adjustment through the drive rod 13 and the bushing 14, so that the guide lower cone wheel 15 is aligned with the upper cone wheel and contacts the tire. The tire tread at the bottom of the wheel is clamped. The controller starts the motor 9, and the drive wheel 8 drives the turntable 17 to rotate via the transmission belt 7. The turntable drives the telescopic shaft 16 and the guide cone wheel 15 to rotate. The upper and lower cone wheels cooperate, and the friction drives the wheel to rotate at a uniform speed (default 30r / min). The ball bearings 265 in the axle cylinder seat 26 reduce resistance and ensure stability. The controller controls the electric push rod b18 to move the measuring frame 20 closer to the wheel, and then controls the electric push rod c21 to move the dial indicator frame 28 up and down along the slide rod 30 to adjust the position of the measuring dial indicator 27 (radially against the center of the tire tread, axially against the wheel hub flange). The telescopic support rod 19 provides support to prevent swaying. When the wheel rotates, the dial indicator transmits the displacement to voltage signal to the controller. Data is collected at a frequency of 100Hz, with 360 points collected per revolution.
