High-precision synchronous relation laser welding equipment

The utility model relates to the technical field of welding equipment, in particular to high-precision synchronous relation laser welding equipment. The high-precision synchronous relation laser welding equipment comprises a synchronous rotation device and a welding device, wherein the synchronous rotation device comprises a workbench; a servo motor and three driving wheels which are controlled by the servo motor to synchronously rotate are arranged on the lower surface of the workbench; the three driving wheels are respectively a first driving wheel, a second driving wheel and a third driving wheel; an air cylinder as well as a first driven wheel, a second driven wheel and a third driven wheel which are respectively in synchronous drive with the first driving wheel, the second driving wheel and the third driving wheel are arranged on the upper surface of the workbench; the first driven wheel is connected with a clamp by a shaft; the second driven wheel is connected with an ejection mechanism by a shaft; the third driven shaft is connected with a guide clamping synchronous mechanism by a shaft. According to the high-precision synchronous relation laser welding equipment, front welding and reverse face welding are adopted, all-around welding is realized at a welding part, the welding effect is good, and the welding sealing property is good.
