Auto gage positioning pin
The location of the positioning holes is determined according to the part drawing RPS system (usually two positioning holes per part). The positioning pin is composed of three parts: guide, positioning and handle to ensure that the guiding part of the pin can enter and exit freely in the positioning hole.
Marking the positioning pin: Mark the pin brand and corresponding RPS point name in the handle groove
According to the RPS characteristics of the parts, the positioning pins are set into cone pins and column pins accordingly.
In the positioning hole, in order to ensure the accurate positioning of the positioning pin, the guide sleeve must be installed, the guide sleeve and the gage type body bonding.
The positioning accuracy of the center of the guide sleeve relative to the coordinate line of the body is controlled within +/0.05mm.
The structure of the positioning pin and the corresponding guide sleeve is divided into anti-rotating structure and non-rotating structure according to the different requirements of the shape of the hole.
Each positioning pin is equipped with a 3mm nylon rope, and it is fixed in the appropriate part of the gage body.
Placement of the pin box: the positioning pin and the detection pin should be placed in the pin box after use, and held with a chuck. The pin box is arranged in the appropriate position on the side of the gauge body and the upper part of the bottom plate.
In the fixture drawings, the positioning pins and positioning holes must be clearly stated.
