Problems solved by technology
These plastic parts in the car compartment will continuously rub against their surfaces during the daily use of the car; therefore, the strength of the friction resistance of the surface of these plastic parts is a very important parameter, but at present, for these plastic parts There are few tests and studies on the parameters of the friction resistance of the surface layer; so the present invention aims at this problem and designs a curved surface sliding friction test device for automotive plastic parts, which is specially designed for the curved surface friction test of the plastic parts inside the car compartment.

Embodiment Construction
[0027] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0028] Such as figure 1 As shown, a curved surface sliding friction test device for automobile plastic parts includes a counterweight 9, a friction cloth strip 5, a test box 7, a frame 1, and a bidirectional rotating actuator 2 arranged on the frame is arranged in the test box The guide roller 4 and the fixed cylinder 6 for installing the plastic sample, and when the plastic sample is pasted and fixed on the surface of the fixed cylinder, the plastic sample is correspondingly arc-shaped. The frame is located outside the test chamber. There is an escape port on the side of the test box. The fixed cylinder is horizontally fixed on the upper part of the inner wall of the test chamber by bolts. The guide rollers are rotatably set in the test chamber through the horizontal shaft, and the guide rollers are located under the fixed cylinder.

The invention discloses a curved surface sliding friction test device for automobile plastic parts, and aims to provide a curved surface sliding friction test device capable of effectively detecting the strength of the friction resistance of plastic parts inside the automobile compartment. It includes a counterweight, a friction cloth strip, a test box, a frame, a two-way rotating actuator set on the frame, a guide roller set in the test box, and a fixed cylinder for installing plastic samples; the fixed The cylinder is horizontally fixed on the upper part of the test box, and the guide rollers are rotatably arranged in the test box through the horizontal rotating shaft, and the guide rollers are located under the fixed cylinder.
Description
technical field [0001] The invention relates to a test device, in particular to a curved surface sliding friction test device for automobile plastic parts. Background technique [0002] A large part of the parts inside the car compartment are plastic parts, such as car interior parts. These plastic parts in the car compartment will continuously rub against their surfaces during the daily use of the car; therefore, the strength of the friction resistance of the surface of these plastic parts is a very important parameter, but at present, for these plastic parts The test and research of the parameters of the friction resistance of the surface layer are seldom; so the present invention aims at this problem, and designs the curved surface sliding friction test device for automotive plastic parts, which is specially designed for the curved surface friction test of the plastic parts inside the automobile compartment. Contents of the invention [0003] The purpose of the present...
