The invention relates to a method for mounting a test simulating rack of a wiper. The method comprises the following step of: adjusting a mounting beam lower supporting slide block, a mounting beam upper supporting slide block, a back beam upper supporting slide block and a back beam lower supporting slide block to change upper and lower positions of an upper supporting shaft, and thus obtaining a plurality of different triangular structures of a front supporting shaft, the upper supporting shaft and a back supporting shaft; and performing left and right, up and down, or front and back and rotary adjustment by using a wiper mounting clamp to obtain different included angles formed by a windscreen mounting beam and a horizontal plane, and the mounting position of the wiper so as to perform technical test on the wiper. A device for mounting the test simulating rack of the wiper is characterized in that the upper supporting shaft is arranged at intersection of the windscreen mounting beam and the back beam; the mounting beam lower supporting slide block is arranged on the front supporting shaft, the back beam lower supporting slide block is arranged on the back supporting shaft, and the mounting beam upper supporting slide block and the back beam upper supporting slide block are arranged on the upper supporting shaft; and the wiper mounting clamp is arranged on a front longitudinal beam. By the method and the device, the mounting inclination angle of an automobile windscreen and the mounting position of the wiper can be three-dimensionally adjusted, test design requirements can be met, the versatility is strong, the mounting is convenient, the operation is simple, and the working efficiency is high.
Description
technical field [0001] The invention relates to a method and a device for installing a stand used for testing relevant technical indicators of a vehicle wiper. Background technique [0002] Automobile windshield electric wiper (abbreviated as wiper) refers to an automobile component driven by a motor and capable of wiping rain, frost, snow or dust on the outer surface of the windshield. Its working principle is: the motor drives the connecting rod mechanism consisting of connecting rod and rocker to move through the crank, and drives the left and right scraping rods fixed on the two output shafts to swing up and down in an arc, so that the left and right scraping rods installed on the left and right The rubber wiper blades on the upper side make corresponding wiping movements. [0003] The wiper has a number of technical index tests that require a test bench, such as the durability of the wiper, the frequency of wiping, the braking performance or the wiping area and other t...
