A rotating shaft is provided at the center of the lower side of the disc (18), and a rotating disk (17) is provided around the rotating shaft. The rotating disk (17) is provided with a plurality of arc-shaped grooves (31) that cooperate with the round rods (32). The round rods (32) are slidably disposed in the corresponding arc-shaped grooves (31). A motor (16) is provided on the inner horizontal plate of the U-shaped frame (15), and the output end of the motor (16) is connected to the rotating shaft; A positioning vertical rod (26) is provided on one side of the disk (18). A positioning plate (27) is provided on the inner surface of the positioning vertical rod (26) facing the axis of the disk (18). The point where the plane on the upper side of the positioning plate (27) intersects with the axis of the disk (18) forms a positioning center for calibrating the placement position of the welding ball. A lifting mechanism for adjusting the height of the welding ball is provided at the center of the upper side of the disc (18). The lifting mechanism includes a cylindrical rod (23) coaxially arranged on the disc (18). A sleeve (24) is provided around the cylindrical rod (23) through a threaded structure. A frustum (25) for placing the upper welding ball (9) is coaxially arranged at the upper end of the sleeve (24). A handle (21) with a ring structure is provided around the sleeve (24). The axis of the arc-shaped plate (11) coincides with the positioning center; Both of the arc plates (11) are provided with through grooves, and corresponding arc grooves (34) are provided on the opposite sides of the through grooves. Matching arc sliders (40) are provided in the arc grooves (34) on both sides, and the clamping mechanism (12) is provided between the arc sliders (40) on both sides.

2. The auxiliary support device for welding a ball net frame according to claim 1, characterized in that, A groove is provided on the upper surface of the positioning vertical rod (26), and an L-shaped positioning rod (29) is slidably arranged in the groove. The free end of the L-shaped positioning rod (29) is provided with a positioning circular plate (28) coaxial with the disc (18). A locking bolt is provided on the outer surface of the positioning vertical rod (26) through a threaded structure, which passes through the groove. A corresponding handle (30) is provided on the outer end of the locking bolt.

3. The auxiliary support device for welding a ball net frame according to claim 2, characterized in that, The clamping mechanism (12) includes a pair of support plates respectively disposed on the arc-shaped sliders (40) on both sides. An outer annular plate (35) is disposed between the two support plates. An annular groove is disposed on the inner arc surface of the outer annular plate (35). A matching annular block is movably disposed in the annular groove. An inner annular plate (37) is disposed on the annular block. Several sets of circular shafts are evenly disposed along the circumference of the inner annular plate (37). A clamping rod (36) is rotatably disposed around the circular shaft. A limiting shaft is disposed on the outer side end of the clamping rod (36) away from the axis of the inner annular plate (37). Several sets of limiting grooves (39) that cooperate with the limiting shafts are evenly disposed along the circumference of the outer annular plate (35). The limiting shafts are disposed in the limiting grooves (39) on the corresponding side. A cylindrical clamping end (38) is disposed on the inner side end of the clamping rod (36).
