Abstract

The invention discloses an automatic alignment device and method for circumferential micro-hole laser processing. The device comprises a rotary servo motor, a counter bore bottom surface, a clamping jaw, a lens, a CCD, an installation plate, a laser processing head, X, Y and Z axis servo motors, a Z servo driver, a controller, a display, X, Y and Z axis lead screws and a laser range finder; the display is connected with the controller; the controller transmits a signal to the servo driver; the servo driver drives the X, Y and Z axis servo motors to drive the X, Y and Z axis lead screws to rotate; the X, Y and Z axis lead screws are mounted on a mounting plate through fixing seats; the controller drives the rotary servo motor to drive parts to rotate; the counter bore bottom surface rotatesaround the axis of the parts along with the rotary servo motor; the CCD, the laser range finder and the laser processing head are fixed at the lower end of the mounting plate; the lens is fixed at the lower end of the CCD; and the parts are fixed on a machine tool through the clamping jaw. The problems of manual alignment, low offline alignment efficiency and low accuracy in existing circumferential micro-hole laser processing are solved.

Description

technical field [0001] The invention belongs to the technical field of processing, in particular to an automatic alignment device and method for circumferential micro-hole laser processing. Background technique [0002] The machined circumferential micro-hole parts are used in the field of hydraulic control, and the perpendicularity between the circumferential micro-hole and the surface of the counterbore to be machined affects the response speed of the hydraulic system. In production, hydraulic system failure is often caused by unqualified verticality. Therefore, we try to adopt a stable and reliable method and device to control the verticality of the processed circumferential micro-hole and the bottom surface of the counterbore. At present, the positioning method of circumferential micro-holes mainly uses the offline alignment of the traveling fixture and the online alignment integrated with the traveling fixture. This alignment structure has disadvantages such as complica...
