1: Horseshoe-shaped indenter clamping method: the material of the chuck is aluminum, and the opening should be larger than 6.5mm. The people's inspection tools usually use this method. The three-coordinate measuring machine can measure the base of the RPS positioning surface. In order to reach this target, the clamp arm should not exceed the base of the RPS positioning surface, otherwise the three-coordinate probe will be blocked by the clamp arm and affect the measurement. If there is still a positioning or inspection pin at the positioning surface, it should be noted that the clamp should not interfere with the positioning or inspection pin when the clamp is opened, which affects the maneuverability.
2: Positioning surface and clamping: In principle, there is a need for clamping of each positioning surface. The clamping point should be located at the base of the positioning surface. The clamping target should be clamped to the normal direction of the positioning surface. common. The angle of the positioning surface and the angle of the support surface of the clamp are less than 5 degrees, and if it is greater than 5 degrees, the clamping target of the clamp should be normal with the positioning surface.
3: Push-pull clamping: including clamps and spring clamps, etc., usually should be considered with clamping clamps.
