Expanding Locating Pin | Locating Pin And Bushing

Locating pin can be divided into many kinds according to its classification. Since it is said to be a pin, it is generally round and has a diameter of the main body. There are many kinds, for example: one end is round and the other end has screw teeth. This is a guide pin, which is commonly used for two parts that are often separated and combined. Of course, there are also some relative position tolerances that are too large, it is difficult to ensure that the circle is used. Pins can be inserted.

The locating pin also has a second function, which is to replace and install the parts that have precise position requirements, and those that are replaced more frequently (some are called wearing parts) need to be quickly replaced and installed. If there is no locating pin, it will be quite troublesome. It's hard to find the original location.

Locating pins are very common for mechanical designers, and they are very useful. First, let’s introduce the positioning pins. The positioning pins are actually an informal name. The strict name is pins, which are used to accurately limit The connection components of the position and coordinates of the parts, usually only the two components that need to be matched need to be added.

The locating pin can use a conical pin, the head is also round, but it is relatively small, and it is easy to guide the product with the hole offset, and some have a larger diameter on the top than the bottom, and the bottom is smaller than the top, and even some are A small flange is added in the middle. This difference in shape can be applied to different occasions, but there is one purpose, that is, the two parts are often clutched.
