Locating Pins Flat Flange, Tip Shape Selectable

MISUMI

Product Overview

The locating pin is used for the spatial positioning in the directions of X and Y axes, mainly using the workpiece hole as the positioning benchmark or used in conjunction with bushings. The flanged locating pin, which is easy to install, is suitable for applications where the holes of the mounting part and those of the locating part are in different positions.

③Reference value for thread mounting torque The tightening torque (reference value) is the strength class (8.8) in the technical data

here, and the tightening state lasts for more than 24 hours. Not applicable when using locking agents or spring washers.

Example of Use

Example introduction: Round and diamond types combined for positioning
①The combination of round and diamond types in the fixture enables more accurate positioning in A direction and reduction of the mating hole pitch error in B direction.
②Of the 2 locating pins, the cylindrical shape is taken as reference for 1 locating pin, and the cut-flat position on the round shape (diamond type) in the direction of the center distance of the two holes is taken as reference for the other, which enables mounting/dismounting operations and ensures positioning accuracy.
③Taking advantage of the different heights of the 2 locating pins, insert the tall pin for pre-positioning and then the short pin for precise positioning.
