Embodiment Construction

[0013] Below in conjunction with specific embodiment and accompanying drawing, the present invention is further elaborated and illustrated:

[0014] Please refer to figure 1 , a calibration method for a tire balancing system, suitable for a tire balancing machine, comprising the following steps:

[0015] (1) Install the first pressure sensor 11 and the second pressure sensor 12 under the main shaft 10, install the screw rod, start the motor, and obtain the vector data AO and the second pressure sensor 11 of the first pressure sensor 11 in this state when the main shaft 10 is idling. The vector data BO of the pressure sensor 12 needs to be subtracted from the vector data AO and B0 in the actual unbalance test to eliminate the unbalance of the main shaft.

[0016] Fix a tire 20 on the main shaft 10 flanges, obtain the distance distA between the tire 20 and the measuring ruler 30, the width wid of the tire 20, the radius R of the tire 20, the distance distB between the first pre...

Abstract

The invention discloses a calibration method for a tire balance system. The calibration method comprises the following steps of acquiring vector data AO of a first pressure sensor and vector data BO of a second pressure sensor in the state when a main shaft is idling; arranging a tire on the main shaft to obtain a distance distA between the tire and a measuring scale, the tire width wid, the tireradius R, and a distance distB between the first pressure sensor and the second pressure sensor; rotating the main shaft to acquire vector data A1 and B1; loading a balance block with the mass of m1 on the inner side surface of the tire, and rotating the main shaft to obtain vector data A2 and B2; transforming the position of the balance block to obtain vector data A3 and B3; recording third position data Delta acquired by a grating disk; and finally, calculating to obtain calibration parameters K1, K2, K3, K4 and K5 according to the above data. According to the calibration method for the tirebalance system provided by the invention, the amount of unbalance of a measuring shaft is eliminated, so that the measurement becomes accurate; and meanwhile, the technological requirements for mechanical production are reduced, and the large-scale production is facilitated.

Description

technical field [0001] The invention relates to the technical field of tire balance detection, in particular to a calibration method of a tire balance system. Background technique [0002] A tire balancer is a device that measures whether a tire is balanced under high-speed rotation. The linear spindle tire balancing machine consists of a motor, a spindle with a flange, a chassis, a signal sensor, a grating disc, a control and calculation module, etc. The operator fixes the tire to be balanced on the main shaft flange, and the motor drives the main shaft to rotate. The signal sensor collects the unbalanced signal and sends it to the control and calculation module for calculation, and finally obtains the unbalanced mass and phase of the tire. [0003] Before using the tire balancer, the measurement system needs to be calibrated. The calibration is to obtain the calibration parameters from the known unbalance, and the actual unbalance test is to obtain the unbalance from the ...
