Supporting jack for machining and aligning shell blank casting in four-axis machining center

Abstract

The invention discloses a supporting jack for machining and aligning a shell blank casting in a four-axis machining center, which solves the problem of low work efficiency of alignment work enabling the central axis of the shell blank casting to coincide with the central axis of a rotary platform of a non-linkage four-axis machining center when the shell blank casting is machined at the non-linkage four-axis machining center. A hemispherical bulge (21) is arranged on a rotary bearing inner ring fixing seat (20), a hemispherical groove (24) is formed in the center of the lower bottom surface ofa cube-shaped rotary seat (22), and a rotary bearing (28) is arranged between a rotary bearing outer ring fixing seat (25) and the rotary bearing inner ring fixing seat; a horizontal lead screw mounting seat (26) and a horizontal lead screw (31) are arranged on the cube-shaped rotary seat on the outer side of a lead screw mounting groove (27), a lead screw nut block is connected to the horizontallead screw in a threaded mode, and a supporting jack is fixedly connected to the lead screw nut block. The alignment work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a supporting device for machining a casting blank cavity after marking, in particular to a jack supporting device for marking and machining the inner and outer cavity structures of a shell blank casting. Background technique [0002] Before machining the inner and outer cavities of the blank casting of the special-shaped shell, it is necessary to scribe the shell, and perform machining according to the scribed lines on the inner and outer walls of the shell; the existing three-coordinate marking method is to Determine a scribing reference plane on the workbench, install the scribing mechanism on the determined datum surface, then place the blank casting of the special-shaped shell on the three jacks on the scribing workbench, pass the scribing mechanism, and The scribing reference plane is used as the reference, and the X-direction leveling and X-direction scribing of the special-shaped shell blank casting are started. After th...
