Problems solved by technology

[0005] The main purpose of the present invention is to provide a laser measuring and positioning device for a wheel balancing machine that uses a laser to guide and paste lead weights at an accurate position and its use method, which can measure the parameters of the tire to be tested, and can also measure the different parts of the tire to be tested. The laser positioning of the balance position solves the problem that the unbalanced position cannot be accurately determined when the balance measurement of various wheels, especially the commonly used aluminum alloy wheels that cannot be balanced by external clamping, and realizes the automatic measurement of various tire parameters

Abstract

The invention discloses a laser measurement and positioning device and a using method of a wheel balancer. The laser measurement and positioning device adopts a stepping motor to drive a laser transmitter to rotate till laser is pointed to the inner side edge of a measured tire, calculates an optical distance by utilizing the time from laser transmitting and laser receiving according to an optical principle so as to obtain a straight line distance from a laser head to a laser indication point, utilizes a geometrical mathematic model to calculate tire parameters according to an installing position constant of the laser measurement and positioning device, achieves automatic measurement of various tire parameters and is accurate in measurement and simple in operation. After tire balance calculation is finished, a microprocessor is adopted to convert a triangular side function formed by the detected unbalance position and an original point of the laser transmitter into an angle differential parameter and then sends an instruction to the stepping motor, the stepping motor drives the laser transmitter to rotate to a converted angle, and the laser transmitter enables the laser to be transmitted onto the unbalance position so as to achieve laser positioning of the unbalance position of the measured tire.

Description

technical field [0001] The invention relates to the field of tire balance detection, in particular to a laser measurement and positioning device of a wheel balancer and a method for using the same. Background technique [0002] If the wheels are unbalanced, the vibration of the steering wheel will cause the steering wheel to vibrate, which will affect the comfort of the driver. Moreover, it will also accelerate the wear of the axle and bearings, the wear of the suspension and steering system components, and the tire tread and the ground. It will cause abnormal wear and tear, which will seriously affect the service life of the tire. The most important thing is that it may involve personal safety at high speed, such as tire blowout, uncontrolled direction, rollover and so on. In order to solve the problem of unbalanced tires, people have manufactured a wheel balancer—a device used to measure the unbalanced amount of a car wheel and indicate the position of the unbalanced amoun...
