Description
Technical field
The present invention relates to welding technology field, refer in particular to rotary electric arc narrow gap welding method and device that a kind of hollow shaft motor drives.
Background technology
Rotating the arc narrow gap welding is a kind of novel narrow gap welding method, it makes the welding torch conducting rod around himself axis rotation with mechanical means, drive the electric arc that passes the welding wire end from eccentric ignition tip and do the rotation sweep motion, thereby obtain uniform and stable two side fusion penetration.Rotating the arc technology can also be used for non-narrow gap arc welding occasion, to obtain good appearance of weld.Welding torch is the key mechanism that realizes rotating the arc welding technology.
Narrow gap welding torque in the existing high-speed rotary arc welding equipment, the Japan Patent spy opens clear 58-176073 number, realizes the conducting rod motion by a pair of gear drive.The shortcoming of this mechanism is: 1. adopt common electric machine to drive, realize the conducting rod motion by gear drive, the driving member consumed power need be used than heavy-duty motor, make that welding torch mechanism size and weight are bigger, and noise is big, and the accuracy of manufacture requires high.2. rely on two independent spring effects that feeder panel is contacted with rotary brush and realize the welding feed, it is little to compress the scope of putting forth effort, and to two spring parameter uniformity and compress the impetus symmetry and require highly, easily cause thrust skewness along the circumferential direction, shorten the service life of critical component brush.3. only adopt and stretch into clearance type gas shield nozzle, feasible protection deleterious several roads weld seam (particularly cap weld) behind the multilayer welding.
Existing rotation sweep welding torch, application for a patent for invention number: 03118177.5, it adopts, and hollow shaft motor drives, the brush feeding classification.The scaning welding torch shortcoming of this structure is: the 1. oblique layout of ignition tip can not extend in the groove of narrow gap, thereby can not be used for narrow gap welding and connect.Big electric current when 2. welding directly flows through motor shaft, makes to select for use copper material to make motor shaft, and in order to guarantee that motor shaft has enough rigidity and conductive area, just needs to use larger-diameter motor shaft, thereby increased the welding torch volume.3. brush radially slides the mode that realizes the welding feed that cooperates with conducting rod, needs to conduct electricity simultaneously with the polylith brush, makes wiper mechanism complicated, the also inconvenient simultaneously maintenance to brush.
Summary of the invention
The purpose of this invention is to provide a kind of practical rotary electric arc narrow gap welding method, and simple and compact for structure, the lightweight rotating the arc narrow gap welding tipping that cooperates is with it put.
Realize the welding method of above-mentioned purpose, it is characterized in that adopting hollow shaft motor directly to drive conducting rod and drive the straight type ignition tip motion that to stretch into the gap, and adopt single holddown spring to make brush become closely to be slidingly matched with conducting rod flange table top, and the cable through connecting firmly on brush becomes conduction to be connected realization welding feed by connector and coupling head, make and pass motor-hollow axle and conducting rod centre bore and produce electric arc from the welding wire end that the ignition tip eccentric orfice is sent and rotate around the conducting rod axis, simultaneously the multi-form external nozzle mechanism of adapted and/or stretch into the clearance type nozzle mechanism realizes that the different rotating the arc narrow gap welding that require connect.
