Classification
Classification by Machine Tool
Lathe fixtures: Used on lathes to hold workpieces for rotary machining, such as three-jaw chucks and four-jaw independent chucks, ensuring the workpiece's rotational axis aligns with the lathe's main spindle axis.
Milling machine fixtures: Installed on milling machines to secure workpieces, maintaining stability during milling, including vise, indexing heads, and rotary tables.
Drilling machine fixtures: Also known as drill jigs, primarily used for hole and thread machining. They consist of bushings, drill templates, and locating and clamping mechanisms, guiding the drill bit for accurate hole machining.
Boring machine fixtures: Also known as boring jigs, used for machining precise holes and hole systems on parts like housings or brackets. They mainly consist of a base, support, bushings, boring bars, and necessary locating and clamping devices.
Classification by Specialization
General-purpose fixtures: Standardized and usable for machining various workpieces within a certain range. They offer wide adaptability but lower production efficiency, suitable for single-piece and small-batch production, such as three-jaw and four-jaw independent chucks on lathes, and vises on milling machines.
Special-purpose fixtures: Designed for a specific operation on a particular workpiece. They are compact, quick, convenient, and labor-saving, ensuring high machining accuracy and production efficiency. However, they have longer design and manufacturing cycles and higher costs, suitable for mass production of fixed products.
General-purpose adjustable fixtures and group fixtures: Some components of the fixture can be replaced, and some devices can be adjusted to adapt to the machining of different parts. Fixtures used for group machining of similar parts are called group fixtures. General-purpose adjustable fixtures have a less defined range of machining objects than group fixtures and a wider range of applications.
Combination fixtures: Assembled from a set of pre-manufactured standard components and parts according to the machining requirements of the parts. They are flexible and versatile, with short manufacturing cycles and reusable components, especially suitable for new product trials and small-batch production.
In-line fixtures: Used on automatic lines, they hold workpieces and integrate with them, moving along the automatic line from one workstation to the next for different machining operations.
