Abstract

A gantry type bearing laser processing device comprises four parts of mounting base, synchronous belt sliding mechanism, gantry and tailstock. The gantry has three degrees of freedom, and a 90-degree right-angle laser head is mounted thereon. The laser head moves up and down and left and right in a vertical plane by using a lead screw sliding mechanism. The gantry moves in the front-back direction by using the synchronous belt sliding mechanism on the mounting base. The rotating tailstock has two degrees of freedom, and drives the three-jaw chuck to rotate as a whole by using the synchronous belt transmission. Meanwhile, the tailstock can rotate the three-jaw chuck from the horizontal clamping state to the vertical clamping state. The device has five degrees of freedom, and can realize laser processing of bearing radial inner and outer wall curved groove, micro-hole and other micro-texture morphology, and laser processing of bearing flat end face. The gantry structure of the device can adapt to the size change of the inner and outer diameters of the bearing and end face processing. The whole processing device can easily realize automatic laser processing of the bearing.
