Description

Quick-replacement welding gun modularized structure Technical Field The utility model relates to the technical field of welding equipment, in particular to a modularized structure of a quick-change welding gun. Background Soldering machines are devices for joining various fusible alloy (solder) metal parts, and are of many kinds, including single-point single-function, single-point dual-function, single-point multi-function, and the like. The welding robot is generated for replacing manual welding, belongs to one type of welding machine, has the advantages of high automation degree, labor saving and the like, and is generally provided with a welding gun at the tail end for working. The end of current welding robot is mostly equipped with a welder only, when welder damages or when needs adopt the alternate operation of different welding modes, need manual dismantlement and change welder, because welder long-time operation, the temperature is higher, and manual change very easily takes place the scald to manual change rifle process is loaded down with trivial details and has reduced welding efficiency. Disclosure of utility model The utility model provides a modularized structure of a quick-replacement welding gun, which solves the problems that the welding process is single due to inconvenient replacement of a traditional welding gun at the tail end of a welding robot, alternative operation of a plurality of welding processes cannot be met, and the welding efficiency is reduced due to manual replacement of the welding gun. The utility model provides a modularized structure of a quick-change welding gun, which comprises a positioning shaft, wherein the lower end of the positioning shaft is coaxially provided with a positioning disc, the bottom of the positioning disc is coaxially provided with a rotating shaft, the upper end of the rotating shaft is rotatably connected with a shaft seat arranged at the bottom of the positioning disc, the upper surface of the positioning disc is provided with a motor, an output shaft of the motor penetrates through a mounting hole in the positioning disc and extends to the lower side of the positioning disc, an output shaft of the motor is coaxially and fixedly provided with a driving gear, the rotating shaft is coaxially and fixedly provided with a driven gear, the driving gear and the driven gear are mutually meshed and are in transmission fit, the lower end of the rotating shaft is coaxially provided with a rotating disc, the bottom of the rotating disc is provided with a plurality of guide rods along the circumferential direction, a guide sleeve capable of guiding and moving along the guide rods is sleeved on each guide rod, a telescopic rod is arranged on the rotating disc above each guide sleeve, the telescopic end of each telescopic rod penetrates through the rotating disc and is connected with a connecting seat arranged on the side wall of the corresponding guide sleeve, each welding gun fixing seat is arranged on the side wall of the guide sleeve, and each welding gun fixing seat is arranged on the welding gun fixing seat. Further, a positioning hole is formed in each welding gun fixing seat, a threaded hole is formed in the inner side wall of each positioning hole, and an adjusting screw used for fixing the welding gun in each positioning hole is arranged in each threaded hole.
