[0030] The working principle of this type of welding fixture for automotive front door window frames will be explained in detail below.

[0031] like Figure 1-5As shown, when welding the front door window frame of a car, firstly, the hydraulic telescopic cylinder 3, servo motor 51, electric telescopic rod 6, vacuum pump 81, and electric telescopic rod 91 are electrically connected to the control panel 10. Then, the device is powered on, and multiple suction cups 84 are screwed into several internal threaded tubes 832 through external threaded tubes 841. The control panel 10 is activated to start the electric telescopic rod 91 (model ZC01A). The output end of the electric telescopic rod 91 pushes the moving plate 92 upward to move the slider 94 along... Move the slide rail 701 to the top, then close the electric telescopic rod 91. Operate the control panel 10 to activate the two electric telescopic rods 6 (model LS-L35S). The output shaft of the electric telescopic rod 6 drives the L-shaped clamp 7 to move, positioning and clamping the front and rear ends of the front door / window frame, placing the lower surface of the front door / window frame on the suction cup 84. Operate the control panel 10 to activate the electric telescopic rod 91. The output end of the electric telescopic rod 91 retracts downwards, moving the moving plate 92 to the upper surface of the front door / window frame, thus securing the anti-slip plate. The sliding pad 93 is attached to the surface of the front door window frame. Then, the vacuum pump 81 (model VN-C4) is started. The vacuum pump 81 draws air through the mounting pipe 82, connecting pipe 83, and connecting hole 840, so that the suction cup 84 is in a vacuum state with the front door window frame, allowing the suction cup 84 to be firmly attached to the lower surface of the front door window frame. This positions and fixes the front door window frame onto the L-shaped clamp 7. During the welding process, when the front door window frame is flipped, the hydraulic telescopic cylinder 3 (model 140H-8R) is started through the control panel 10. The output end of the hydraulic telescopic cylinder 3... The front door window frame is lifted by the L-shaped plate 4, and then the servo motor 51 is started. The output shaft of the servo motor 51 rotates the turntable 53 through the rotating column 52, so that the turntable 53 drives the front door window frame to rotate through the electric telescopic rod 6 and the L-shaped clamp 7. During the rotation, the positioning arc plate 54 slides along the inside of the annular groove 530 and drives the ball bearing 55 to roll along the inner wall of the annular groove 530, improving the smoothness and stability of the rotation. When the rotation reaches the appropriate angle, the servo motor 51 is turned off, and then the welding of the front door window frame continues.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
