Abstract

The invention discloses a lathe chuck for an aluminum alloy hub. The lathe chuck for the aluminum alloy hub mainly comprises a pull rod shaft, a positioning unit fixing base, a protective cover, a hollow shaft sleeve and the like. An upper cover and a chuck body are connected through screws, so that a chuck main body is formed. An installation hole is formed in the bottom of the chuck body so that the chuck can be installed on a machine tool. Positioning pins are installed between the upper cover and the chuck body through screws. The pull rod shaft, an annular pressing plate and a tensioning plate are connected through screws. The tensioning plate is in sliding fit with the positioning pins through copper sleeves. The positioning unit fixing base, the protective cover and the hollow shaft sleeve are combined together through screws. A spring, sliding blocks and a wedge-shaped taper sleeve are installed inside. When the wedge-shaped taper sleeve moves up and down, the sliding blocks can be driven to slide leftwards and rightwards, and each sliding block is connected with a transverse pull rod through a screw and drives a step-shaped positioning block to slide leftwards and rightwards through the transverse pull rod; a crankshaft pressing claw is installed on the upper cover through a hinge pin, a ball at the lower end of the crankshaft pressing claw is inserted in a groove of the tensioning plate, and a connection pop rivet is used for connecting the chuck with the machine tool.

Description

technical field [0001] The invention relates to a lathe chuck, in particular to an aluminum alloy wheel hub lathe chuck. Background technique [0002] At present, the conventional machining process of aluminum alloy wheels is generally divided into three processes, namely, the first-order turning process, the second-order turning process, and the third-order drilling process. Among them, the first-order turning process is to place the blank of the aluminum alloy wheel hub on the chuck, perform necessary positioning and clamping, and then perform turning on the CNC lathe according to the program. [0003] Since the blank is objectively affected by the deformation of the pre-sequence heat treatment, the metal processing allowance, and the difference between different molds, positioning and clamping work are particularly important in the alignment process of the first-sequence blank. Therefore, compared with the fixtures used in the second-order turning process and the third-o...
