Description

Automatic laser drilling machine for fastener Technical Field The invention relates to the technical field of laser drilling, in particular to an automatic laser drilling machine for a fastener. Background The metal cutting equipment manufacturing is used as a core subdivision industry in the field of high-end equipment manufacturing, is a key technical support in the industries of fastener precision machining, engineering machinery matching, high-end equipment production and the like, and the technical iteration and product upgrading of the metal cutting equipment directly determine the machining precision, mass production stability and production efficiency of metal precision molding. The laser drilling technology has become the main technical direction for precision small hole machining in the field of metal cutting equipment manufacturing by means of the core advantages of non-contact machining, no cutter loss, adaptation to complex hole patterns, high-strength difficult-to-machine materials and the like, and the corresponding automatic laser drilling machine can realize continuous and batch drilling operation of fastener workpieces by integrating functional modules such as automatic feeding, visual positioning, numerical control laser machining and the like. The automatic laser drilling machine can enable metal materials at the head of the lead sealing screw bolt to be melted, gasified and removed rapidly through the thermal effect of high-energy-density laser beams aiming at special fasteners with anti-disassembly locking function holes such as lead sealing screws, and the lead sealing holes meeting the requirements of anti-tampering and anti-loosening locking are formed by matching with a numerical control system to accurately control a processing path and action duration, so that the lead sealing device is core processing equipment in the current lead sealing screw industrial mass production. The automatic laser-beam perforating machine of current metal cutting equipment manufacturing field production, mostly focus on the shaping process itself that punches of plumbous hole sealing only, generally lack supporting processing agency and full flow processing ability after to plumbous seal screw laser drilling, can't carry out synchronous correction to the inherent defect that laser drilling produced and handle, seriously influence the shaping effect of laser drilling and the follow-up result of use of plumbous seal screw. Specifically, the problems of edge collapse of an orifice, annular recasting layer of an orifice wall, burrs of an inner wall, deviation of aperture taper and the like generated in the laser drilling process can directly lead to the forming precision of lead sealing and the finish degree of the orifice wall not reaching the design requirements due to no subsequent inner wall polishing and orifice correction treatment procedures, the yield and consistency of laser drilling processing are greatly reduced, the sealing wire for locking can be directly cut and clamped by untreated sharp orifices and rough orifice walls in the subsequent use process of the lead sealing screw, so that the anti-disassembly and anti-tampering core functions of the lead sealing screw are completely disabled, and meanwhile, the problems of local thermal deformation, hole position deviation and the like generated by laser drilling do not have matched calibration correction procedures, so that the pre-tightening force distribution and sealing surface leakage can be caused during lead sealing screw assembly, the forced compliance use requirements of scenes such as metering devices, special equipment and the like can not be met, and the mass production efficiency and the long-term use reliability of the lead sealing screw are seriously restricted.
