Portable swing angle testing device for automobile windscreen wiper

Abstract

The invention discloses a portable swing angle testing device for an automobile windscreen wiper. The portable swing angle testing device comprises a dial. A fixing base for fixing the dial is arranged at the lower end of the dial; the dial is provided with a major arc-shaped guide groove, angle scribed lines are arranged in the extending direction of the guide groove; the dial is provided with ashaft hole at the circle center of the guide groove; a rotating shaft connected with a windscreen wiper rotating shaft is in sliding fit with the shaft hole; a poke rod is fixedly connected on the upper end of the rotating shaft; a left pointer and a right pointer are arranged on the left side and the right side of the free end of the poke rod respectively. Cylinders extending downwards are arranged on the left pointer and the right pointer; the cylinders are in sliding fit in the guide groove through rollers; a magnet block is fixed to the lower end face of each cylinder, a bottom plate madeof ferromagnetic materials is fixed to the lower end of the dial guide groove, a gap is reserved between the bottom plate and the magnet blocks, the opposite faces of the left pointer and the right pointer are indication edges, and the indication edges and the central axis of the poke rod are located on the same straight line.

Description

technical field [0001] The invention relates to the technical field of automobile wipers, in particular to a portable swing angle testing device for automobile wipers. Background technique [0002] The car wiper is a device used to brush or scrape off the raindrops and dust attached to the windshield, which is used to improve the visibility of the driver and increase driving safety. After the car wiper is produced, it is necessary to test the swing angle of the wiper to check whether the wiping range of the wiper arm meets the requirements. At present, the test of the wiper swing angle is carried out on the swing angle test bench dedicated to the wiper production workshop. However, because the test bench cannot be moved by the way, when it is necessary to analyze whether the swing angle of the wiper meets the design requirements during the experiment of the wiper product or the loading process of the OEM, the wiper in the laboratory or the OEM can only be removed at present...

AI Technical Summary

Problems solved by technology

However, because the test bench cannot be moved by the way, when it is necessary to analyze whether the swing angle of the wiper meets the design requirements during the experiment of the wiper product or the loading process of the OEM, the wiper in the laboratory or the OEM can only be removed at present. Then take it to the special test bench in the production workshop for testing

The test of the wiper swing angle is cumbersome, time-consuming and laborious, which brings great inconvenience to the development and loading of wiper products, affects the production progress, and reduces the efficiency

Moreover, due to the different installation dimensions of wiper blades, special test tooling is used to test the swing angle of wiper blades at present, and the manufacturing cycle of test tooling is relatively long. Therefore, after the initial development of wiper products, often due to It is impossible to test the swing angle of the wiper before it is manufactured, and the unqualified R&D products cannot be tested in time, which seriously affects the R&D progress
