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 selectable front-end full thread type offers a wide range of lead-in specifications, providing flexible selection.

Example of Use

Example introduction: Positioning application of the relative position of the upper and lower plates of the fixture
Function description:
The position accuracy of the upper and lower plates of the fixture is ensured by the coordinated use of positioning pins and bushings.
Advantages of fixture bushings:
(1) The bushing hardness is slightly lower than the positioning pin, which effectively protects the positioning pin from rapid wear and ensures the positioning accuracy.
(2) The bushing is easy to replace when it wears out, effectively protecting the bottom plate or workpiece from damage.
