[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model relates to an automatic robotic welding fixture for a turntable base plate assembly. By setting up a lifting and adjusting component, activating servo motor one drives a connected lifting platform one to move up and down, achieving linear motion of the top plate on the optical axis guide one, thus vertically positioning different turntable base rings. By setting up a positioning and clamping component, activating servo motor two drives a connected lead screw one to rotate clockwise or counterclockwise. When the lead screw one rotates, it drives the workpiece positioning component and clamping base, which are threaded together, to move linearly on the guide bar, thus horizontally positioning the turntable base ring. Using the rotation axis as a fulcrum, the extension and retraction of the hydraulic cylinder control the pressing head's downward and opening actions, achieving vertical clamping and positioning of the turntable base ring. By setting up a lifting and positioning component, activating servo motor six drives a connected lifting platform two to move up and down, achieving linear motion of the lifting plate on the optical axis guide two, thus vertically positioning different turntable tail counterweight plates. By setting up a sliding table positioning component, activating servo motor seven drives a connected lead screw two to rotate clockwise or counterclockwise, the lead screw... The second component rotates, driving the movable slide 1, which is threadedly matched with it, to move. The movable slide 1 moves linearly on the linear guide rail 1. The tail positioning component on the movable slide 1 achieves lateral positioning of the turntable seat ring for different seat rings. The electromagnet 1 and the support block on the movable slide 1 achieve vertical positioning of the tail counterweight plates of different turntables. By setting the head positioning component, the servo motor 3 is started, driving the lead screw 3 connected to it to rotate clockwise or counterclockwise. When the lead screw 3 rotates, it drives the movable slide 2, which is threadedly matched with it, to move. The movable slide 2 moves linearly on the linear guide rail 2. When the movable slide 2 moves, it drives the positioning plate 1 to move, thereby achieving lateral positioning of the turntable seat ring. By setting the side movable slide component, the servo motor 4 is started, driving the gear 1 connected to it to rotate. Since the gear 1 meshes with the rack 1 on the mechanism body, the gear 1 drives the movable slide 3 to move when it rotates. The movable slide 3 moves linearly on the linear guide rail 3. When the movable slide 3 moves, it drives the fixed support and fixed plate connected to it to move.By setting up a vertical plate positioning component, the servo motor five on the movable slide four is activated, driving the gear two connected to it to rotate. Since gear two meshes with rack two on the mechanism body, the movable slide four moves as gear two rotates.
