Embodiment Construction

[0023] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 , 2 As shown in and 3, the salt spray scratch test equipment of the present invention includes: a base 2, a sample holder 3 arranged on the base 2, a tool mounting frame 5, and a tool holder 4 installed on the tool mounting frame 5 .

[0025] The tool mounting frame 5 may include a vertically extending tool support 51 and a horizontally extending tool holder 52 . In one embodiment, the upper surface of the base 2 may have a guide rail 23, on which the tool holder 51 is arranged and can slide horizontally along. The lower end portion 55 of the tool support 51 can pass through an open chute (not clearly shown) of the base 2 and extend to the bottom of the base 2 . The first driving mechanism is used to drive the tool support 51 to translate relative to the base 2 along the horizontal direction. In one...

Abstract

The invention discloses a salt mist scratch test device which is used for scratching a sample by using a cutter. The salt mist scratch test device comprises a base platform, a sample holding device arranged on the base platform and used for holding a sample, a cutter holding device used for holding the cutter, a cutter installing frame arranged on the base platform, a first driving mechanism used for driving the cutter installing frame to translate relative to the base platform along the horizontal direction and a second driving mechanism used for driving the cutter holding device to rotate in a vertical plane relative to the cutter installing frame, wherein the cutter holding device is arranged on the cutter installing frame, and the cutter installing frame can be vertically adjusted so that the cutter is vertically arranged relative to the sample. The salt mist scratch test device is simple in structure, convenient and simple in scratching and capable of meeting the scratching requirement of salt mist tests, effectively improving the testing efficiency and quality and avoiding hurting an operator in a scratching process.

Description

technical field [0001] The invention relates to the field of machinery, and more particularly relates to a scratching device for carrying out salt spray tests on mechanical parts. Background technique [0002] When conducting salt spray tests on mechanical parts such as auto parts, because the coating of some parts is too thick, in order to better verify the corrosion resistance of the parts, it is necessary to scratch the surface through the coating to the base straight line scratches on the material, and then carry out the salt spray corrosion test. The requirements for scratches are usually: 1. The angle between two scratches is 60 degrees; 2. The length of the scratches is 20-40mm; 3. The width of the scratches is 0.3-1.0mm. [0003] At present, there is no special test equipment for scratching parts samples. When scratching the sample, the manual scratching method is usually used, that is, the human hand scratches with a knife and a ruler, and an angle ruler. Since t...
