Description

Device for testing stone impact resistance of paint film Technical Field The utility model relates to the technical field of paint film testing, in particular to a device for testing the stone impact resistance of a paint film. Background The stone-impact resistance of a paint film refers to the ability of the paint film to withstand impact from external forces such as stones. The principle of the stone chip resistance measurement of paint films is to evaluate the wear resistance and durability of paint films by simulating the situation when a vehicle is impacted by stones during high-speed running. The usual test method for the resistance of paint films to stone-chipping is to evaluate the resistance of paint films to stone-chipping by striking the surfaces of the paint films with standard steel balls and stones of different weights and different speeds. In the prior art, a Chinese patent document with publication number CN115032056A and publication date 2022, 09 and 09 is provided, and the technical scheme disclosed in the patent document is that the paint film impact testing device comprises a base, wherein one side of the base is fixedly connected with a supporting box body, a pipe fitting arranged on the supporting box body, a sliding impact block is arranged in the pipe fitting, and the device further comprises a guide groove, the guide groove is arranged on the pipe fitting, the guide groove is arranged along the length direction of the pipe fitting, and the length of the guide groove is smaller than that of the pipe fitting. The clamping assembly is arranged on the base, the position of the clamping assembly corresponds to that of the pipe fitting, the clamping assembly comprises two bearing rollers which are rotatably arranged on the base, the bearing rollers are located on two sides of the pipe fitting, the clamping assembly further comprises limiting pieces which are arranged on the base and used for tightly pressing the test plate on the two bearing rollers, and a driving structure is further arranged in the base and used for driving one side of the bearing rollers to rotate.
