Precision Coating Scribe

Abstract

The invention relates to a precise coating griding device. The precise coating griding device comprises a base (2), wherein a specimen platform (7) which can horizontally move is arranged on the base, and a bearing support (9) is arranged on one end of the base; the bearing support is divided into a first support section, a second support section and a third support section, a first pulley (12) is arranged on the first support section, a second pulley (11) is pivoted on the second support section, and the third support section is pivoted in the middle of a tension arm (16); a tension arm balancer (17) is arranged on one end of the tension arm, a cutter head (18) is arranged on the other end of the tension arm, and one end, which is far away from the cutter head, of the tension arm is fixedly connected with one end of a pull rope (10) which bypasses the second pulley and the first pulley in sequence and then is connected with a weight seat in a hanging mode; and a tension arm state controller (27) is arranged below the second support section, and the tension arm can be kept in a shutdown state or working state by the tension arm state controller. According to the precise coating griding device, the force applied to a specimen by a cutter blade can be accurately controlled, so that a coating can be effectively scratched completely by the cutter blade, a straight scratching line is guaranteed, and standard measuring requirements are satisfied.

Description

technical field [0001] The invention relates to a coating scratcher, in particular to a precision coating scratcher. Background technique [0002] Coating cross-hatching is a necessary procedure for testing coating adhesion. At present, the existing precision coating scratcher is the way of fixing the blade on the handle. When scratching the coating, it is necessary to manually control the magnitude, direction and angle of the handle force and the angle of the blade. Therefore, the seemingly simple scratching process, Due to the high technical requirements for cross-cutting, it is difficult to draw a grid line that meets the requirements of the standard, and the success rate of cross-cutting is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a precise coating scratcher that can precisely control the scratching force and the scratching track, and make the scratching operation process more convenient, ef...
