metal positioning pin

Concept: The function of the positioning pin is to limit the free movement of the item. Degrees of freedom: Any object in space must have six degrees of freedom, linear motion in the three axes of X, Y, and Z, and rotational motion around X, Y, and Z. The positioning pin is the part that participates in limiting these degrees of freedom. In a mold consisting of two or more parts, a part usually made of cylindrical wood, metal, or other material that accurately positions two adjacent parts of the mold, especially used to fasten several separate items together or As for spindle positioning, 1) mechanical cam mechanism (2) photoelectric disk method is used for rough positioning, and then a hydraulic or pneumatic positioning pin is inserted into the pin hole or pin groove on the spindle to achieve precise positioning. After the tool change is completed, the positioning pin After exiting, the spindle starts to rotate. Guide post A support by which one object is suspended from another.

Application: Positioning pins are most widely used in molds. Including stamping molds, injection molds, etc. Their precision requirements are very high, and it will definitely not work if the template is fixed only by bolts, so the only way to achieve the purpose of positioning is to use positioning pins, or to prevent errors in installation position, direction, etc. It has certain applications in some mechanical motion equipment, mainly used for position determination based on two-dimensional space.
