Test device and test method for surface grinding effect of hand-held sandpaper grinder

Abstract

The invention discloses an evaluation device and evaluation method of the curved surface sanding effect of a hand-held sandpaper sander. According to the evaluation device, on the basis of the advantages of elastic rubber, such as good elasticity and long service life, the profiling of curved surfaces of different radians and curvatures are realized through the cooperation of a power transmissionmechanism, a cam direction adjustment mechanism, a cam jacking mechanism and a test bench modeling surface. The evaluation method provided by the invention is an evaluation method that can scientifically evaluate a sanded curved surface. According to the method, a sanding effect can be quantified, a test can have reliable data support, a variety of curved surfaces can be provided, and test costs can be significantly reduced.

Description

technical field [0001] The invention belongs to the technical field of surface forming equipment, and in particular relates to a test device and a test method for the grinding effect of a hand-held sandpaper grinder on a curved surface. Background technique [0002] As an important mechanical equipment in the pre-polishing process of structural surfaces, hand-held sandpaper grinders are being increasingly used in metal, woodworking, Surface and plane grinding of various materials and structures such as composite materials, such as grinding complex surfaces of structures such as blades and crankshafts, etc. [0003] At present, there is no test device or test platform that can effectively test the grinding effect of hand-held sandpaper grinders on the market. People usually just use hand-held sandpaper grinders directly. The sandpaper grinder lacks a professional test device or test platform to objectively test its actual effect when grinding a curved surface. This will ofte...

Problems solved by technology

[0003] At present, there is no test device or test platform that can effectively test the grinding effect of hand-held sandpaper grinders on the market. People usually just use hand-held sandpaper grinders directly. The sandpaper grinder lacks a professional test device or test platform to objectively test its actual effect when grinding a curved surface. This often causes the sander product to fail to meet the user's requirements, and in severe cases, it may even cause the quality of the polished workpiece to be unqualified and give to the user. cause huge economic losses

For this reason, it is particularly important to design and invent a test bench that can realize the grinding effect test of various processed surfaces, but there is no technology that can solve this kind of problem at present.
