Robot fixture it refers to the device used to fix the processing object and make it occupy the correct position in the process of mechanical manufacturing to accept construction or inspection, also known as fixture (qi ǎ j ǜ). In a broad sense, any process in the technological process, the device used to quickly, conveniently and safely install the workpiece, can be called a fixture.

 Fixture usually consists of positioning element (determining the correct position of the workpiece in the fixture), clamping device, tool Guide element (determining the relative position of the tool and the workpiece or guiding the tool direction), indexing device (so that the workpiece can complete the processing of several stations in one installation, there are two types of rotary indexing device and linear moving indexing device), connecting element and fixture body (fixture base), etc.

        Robot fixture has the characteristics of continuous repetitive work and labor, no fatigue, no fear of danger, and the strength of seizing heavy objects is greater than that of human hands. It can be used to determine the accuracy of object position and shorten the process time, so as to improve labor productivity. Therefore, manipulator has been widely used in industrial production to replace people to complete repeated and regular work, it is widely used in loading and unloading robot engineering of shaft machine tools and various automation equipment.
