Product Description

Product Overview

The positioning 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, in which the straight rod cone head type is simple in shape, easy to install, and widely used.

Product Features

Feature 1: Standard type with cone head. Rod diameter tolerance that can be specified for the press-fit type: m7, p7, g7, h7.
Feature 2: Mounting methods include press-fit type and internal thread type, offering a variety of installation options.
Feature 3: Optional Material: Iron (alloy tool steel or bearing steel); Stainless Steel (austenitic stainless steel, martensitic stainless steel), suitable for positioning of a variety of workpieces.
Feature 4: Hard chrome plated surface, effectively ensuring surface hardness and antirust.
Feature 5: Multiple cone tip angles available, with a wide range of specifications, suitable for installation and positioning in various working conditions.
Feature 6: The installation space is small, and the straight rod cone head type positioning pin is more suitable for simple lateral positioning.

Example of Use

MISUMI Positioning Pin Specifications and Dimensional Drawing Large Head Round

Example introduction: straight rod cone head positioning pin and shouldered bushing in pick and place mechanism
Design summary:
(1) An example of using a swing cylinder to achieve linear and rotary motion through pneumatic drive, and moving a small substrate through a suction cup.
(2) In the case of a long pin, if the air vent is not provided, the pin and bushing are not easy to pull out. It is necessary to provide a air vent on the bushing side or the positioning pin side.
Intended use of fixture bushing:
The axial structure of the swing cylinder can ensure positioning accuracy while saving space through the coordination of positioning pins/shouldered bushings.
