The invention discloses a cambered surface
machining machine tool based on
laser positioning and relates to
mechanical equipment. The problem that when an existing cambered surface
machining instrument works, the whole instrument easily shakes,
machining errors are easy to produce, and the adjustment of the machining instrument is not linear enough during height increase. The cambered surface machining
machine tool comprises a
grinding machine, a main supporting column, an auxiliary supporting column, a cross beam, a
grinding wheel, a first sector plate, a second sector plate, an electric lamp, an
optical fiber and an
optical fiber laser device, wherein the first sector plate and the second sector plate include optical fibers,
optical fiber couplers and optical
fiber collimators, the main supporting column, the auxiliary supporting column and a worm wheel and worm lifter can ensure the working stability of the
grinding machine, and the worm wheel and worm lifter can make the height adjusting process of the grinding machine more linearized. The first sector plate and the second sector plate can achieve positioning of the lower wheel position of the
grinding wheel and can provide auxiliary illumination for the grinding and
polishing process, machining work can be also normally performed in a dark environment, and damage caused by severe shaking in the working process can be prevented by adopting an installing mode of the optical
fiber laser device.
