Turnover jig and turnover mechanism

The turnover jig comprises at least one set of jig assembly, a linkage plate, two sets of fixing plates, a base, a fixing base and a motor, the two sets of fixing plates are arranged at the two opposite ends of the jig assembly respectively and rotationally connected with the jig assembly, and the linkage plate is in transmission connection with the jig assembly; the fixing seat is fixed to the upper end of the base, the two fixing plates are arranged at the two opposite ends of the fixing seat respectively, a storage groove is formed in the base, the motor is arranged in the storage groove, and a rotating shaft of the motor is hinged to the linkage plate. According to the turnover jig and the turnover mechanism, through synchronous inclination of the multiple jig assemblies, multi-angle welding can be conveniently conducted on a welding product on the jig after inclination, the welding comprehensiveness, efficiency and precision are improved, the linkage plate is controlled by the motor to move back and fort
