(1) Positioning element
It is in contact with the positioning reference of the workpiece and is used to determine the correct position of the workpiece in the fixture, thus ensuring the relative correct position of the workpiece with respect to the tool and the machine tool between machining movements during machining.
(2) Clamping device
Used to clamp the workpiece, so that the workpiece in the fixture to maintain the established position during cutting.
(3) Tool setting and guiding elements or devices
The function of these elements is to ensure the correct position between the workpiece and the tool. Elements used to determine the correct position of the tool before machining are called tool setting elements, such as tool setting blocks. Elements used to determine the position of the tool and guide the tool for machining are called guide elements. Such as the quick-change drilling sleeve in Figure 6-1
(4) Connection elements
Make the fixture and the machine tool to connect the components, to ensure that the machine tool and the fixture between the mutual position of the relationship.
(5) Clamp specific
It is used for connecting or fixing the components and devices on the fixture to make it a whole basic part. It is connected with the relevant parts of the machine tool, alignment, so that the fixture relative to the machine tool has a certain position. Such as Figure 6-1 in the clamp specific 7.
(6) Other components and devices
Some fixtures according to the workpiece processing requirements, to have indexing mechanism, milling machine fixtures also have positioning keys and so on.
These components, not for each machine tool fixture is indispensable, but any fixture must have positioning elements and clamping devices, they are to ensure the accuracy of the workpiece machining the key, the purpose is to make the workpiece fixed, clamped firmly.
