Problems solved by technology
[0002] When processing the flange of the aluminum alloy shell on the lathe, the first problem to be solved is how to position and clamp the aluminum alloy shell parts, especially the special-shaped aluminum alloy shell parts, because of their irregular shape, it is impossible to use the lathe Some three-jaw chucks will be positioned and clamped, so special fixtures have to be used to position and clamp them. However, the existing fixtures for aluminum alloy shell parts have complex structures and troublesome positioning, which cannot meet the purpose of batch processing of parts. Moreover, this type of special fixture can only be applied to the positioning and clamping of parts of a single specification, and its versatility is poor

The invention discloses a method and fixture for machining double flanges of an aluminum alloy shell through a lathe. The fixture comprises a chuck (1). A spigot shaft (16) is arranged in the center of the chuck (1), a base plate (4) for limiting displacement of a workpiece is arranged on one side of the spigot shaft (16) and provided with a clamping mechanism, a guide block (19) is arranged at the end where the base plate (4) makes contact with the chuck (1), the guide block (19) can slide in a guide groove (20) of the chuck (1), and an auxiliary supporting assembly capable of adjusting a supporting point is arranged on the other side of the spigot shaft (16). The fixture is simple in structure, ingenious in design, capable of positioning and clamping aluminum alloy shell parts rapidly and high in universality because a positioning and clamping assembly can be adjusted according to shapes and sizes of the aluminum alloy shell parts, and can be applied to machining the aluminum alloy shell parts on the lathe in batch.
