Abstract

The invention discloses a positioning self-centering main shaft chuck capable of overturning plus or minus 180 degrees. The main shaft chuck comprises a swingable clamping expansion chuck (1), a main shaft rotating mechanism (2), a turnover mechanism (3) and a three-loop swivel joint (1). The positioning self-centering main shaft chuck is characterized in that a hydraulic motor (2-8) drives a driven bull gear (2-3) and the main shaft rotating mechanism to rotate; a blank wheel hub is horizontally clamped through self-centering linked three claws to determine a machining center,; after a dead head is cut through the main shaft chuck in positive rotation, the main shaft chuck stops rotating; a hydraulic anti-gravity valve locks a clamp; after reverse slow 180-degree positioning is performed to the chuck, lateral waste material is machined; and after a sensing block (7) is sensed through a photoelectric switch (6), the chuck is immediately stopped, and the machining is finished. The positioning self-centering main shaft chuck has the advantages that the clamp is not required to be centered and positioned manually, centre positioning and overturning are completely automatic, and plus or minus 180 degrees position are automatically determined during machining. The chuck can be conveniently matched with a magic hand to realize automatic work piece loading and unloading, so that unmanned machining can be implemented.

Description

technical field [0001] The invention belongs to the technical field of special-purpose machine tools for mechanical processing, and is applied to large-scale casting processing machine tools, especially blank processing of low-pressure or high-pressure castings of vehicle hubs. Background technique [0002] Aluminum alloy wheels are constantly recognized for their light weight, energy saving, good heat dissipation, aesthetics, corrosion resistance, and good processability. The use of aluminum alloy wheels has become the best choice to replace steel wheels, which has led to a sharp increase in the demand for aluminum alloy wheels for automobiles. . The high speed of automobiles forces aluminum alloy wheels to develop in the direction of large diameter and wide rims. The current mainstream 14-16in is gradually replaced by 17-20in, and even 21-28in wheels appear to be installed on automobiles. The applicant applied for an invention patent in 2011: a reversible spindle chuck, t...
