The dowels are the components involved in limiting these degrees of freedom. Locating pins are the most widely used in molds. The function of the locating pin is to limit the free movement of the item. In a mold composed of two or more parts, a pin used to precisely position two adjacent parts of the mold. Their precision requirements are very high. If the template is only fixed by bolts, it is definitely not. Therefore, only the positioning pins can be used to achieve the purpose of positioning, or to prevent the wrong position and direction of installation. There are some applications in some mechanical motion equipment, mainly for positioning based on two-dimensional space. What is the function of circular positioning? Today, I will introduce the use of circular positioning pins with you.
Introduction of circular positioning pins in positioning pins
The circular positioning pin is one of the most basic positioning pins in the design of positioning elements. Together with the diamond positioning pins, it belongs to the circular shaped positioning pins.
The circular positioning pin is a basic positioning element connector in the design of machine tool fixtures.
Universal Fixture
A universal fixture is a standardized fixture that can be used to machine different parts within a certain range. For example, three-jaw chucks and four-jaw single-action chucks on lathes, flat pliers, indexing heads and turntables on milling machines, etc. Such fixtures are usually produced by professional factories and are usually provided to users as machine tool accessories. It is characterized by wide adaptability and low production efficiency, and is mainly suitable for single-piece and small batch production.
special fixture
A special fixture is a fixture specially designed for a certain process of the workpiece. It has the characteristics of compact structure, quick operation, convenience and labor saving. It can ensure high machining accuracy and production efficiency, but the design and manufacturing cycle is long and the manufacturing cost is high. When the product changes, the fixture will be scrapped because it can no longer be used. For stationary and mass production only.
positioning element
It is used to determine the correct position of the workpiece in the fixture to ensure the relative correct position of the workpiece relative to the movement of the tool and the machine tool during the machining process.
