[0017] The tripod welding fixture provided in this disclosure can achieve the following technical effects: This disclosure provides a tripod welding fixture, comprising a triangular plate, guide rails, sliders, C-shaped plates, screws, pads, a first support column, a first circular plate, and a three-jaw clamp. The guide rails are mounted on the top surface of the triangular plate and are located at three axes of symmetry of the triangular plate, respectively, and are used to support the sliding sliders. The sliders are slidably mounted on the three guide rails, and together with the guide rails, provide guidance and support. The C-shaped plates are mounted on the three sliders and move linearly under the guidance and support of the three guide rails and the three sliders. The openings of the three C-shaped plates all face the centerline of the triangular plate to facilitate clamping and positioning of the tripod. The screws are threaded to the top walls of the three C-shaped plates, and the three screws face the bottom walls of the three C-shaped plates, respectively, and are used to clamp the three pin-shaped pillars of the tripod. The pads are connected to the inner sides of the three C-shaped plates and are directly opposite the three screws, respectively, and are used to position the three pin-shaped pillars of the tripod. Each of the three pads includes a notch, which penetrates the end face of the three pads facing the center line of the triangle, facilitating disassembly of the tripod after welding. A first support post is mounted on the top surface of the triangle to support the first circular plate. The first supports are positioned between adjacent guide rails to prevent interference between components. A first circular plate is mounted on top of the three first supports, its plane parallel to the plane of the triangle, supporting a three-jaw clamp. The three-jaw clamp is mounted on the top surface of the first circular plate to position the conical cylinder at the center of the tripod.

[0018] During use, adjusting the three-jaw clamp will clamp the conical cylinder of the tripod, thus positioning it. Then, the three pin-shaped posts of the tripod are placed on the three pads, and the three pin-shaped posts will engage with the three notches. Next, screwing in the three screws will press the top surfaces of the three pin-shaped posts together through the interaction of the threads, thus positioning them. This allows the three pin-shaped posts to be evenly distributed around the conical cylinder at a certain angle. Then, under the guidance and support of the guide rail and slider, and under the action of external force, the three C-shaped plates can be brought together or separated. This allows adjustment of the distance between the three pin-shaped posts and the conical cylinder, enabling the placement and welding of three strip plates of different lengths between the pin-shaped posts and the conical cylinder. After welding, adjusting the three-jaw clamp again will release the conical cylinder of the tripod. Tighten the three screws again to loosen the three pin-shaped posts of the tripod, thus completing the disassembly of the tripod. The whole process is easy to operate and convenient for welding tripods with three pin-shaped posts at evenly distributed angles.

[0030] Combination Figures 1 to 6 As shown, this embodiment of the present disclosure provides a tripod welding fixture, including a triangular plate 1, guide rails 2, sliders 3, C-shaped plates 4, screws 5, pads 6, a first support column 7, a first circular plate 8, and a three-jaw clamp 9. The guide rails 2 are mounted on the top surface of the triangular plate 1 and are located at three axes of symmetry of the triangular plate 1, respectively, and are used to support the sliding sliders 3. The sliders 3 are slidably mounted on the three guide rails 2, and together with the three guide rails 2, they serve as guides and supports. The C-shaped plates 4 are respectively mounted on the three sliders 3, and move linearly under the guidance and support of the three guide rails 2 and the three sliders 3. The openings of the three C-shaped plates 4 all face the centerline of the triangular plate 1 to facilitate clamping and positioning of the tripod. The screws 5 are threadedly connected to the top walls of the three C-shaped plates 4, and the three screws 5 face the bottom walls of the three C-shaped plates 4, respectively, and are used to press the three pin-shaped columns of the tripod. The pads 6 are connected to the inner sides of the three C-shaped plates 4, respectively, and are directly opposite the three screws 5, used to position the three pin-shaped columns of the tripod. Each of the three pads 6 includes a notch, which penetrates the end face of the three pads 6 facing the center line of the tripod 1, facilitating disassembly of the tripod after welding. The first support 7 is installed on the top surface of the tripod 1 to support the first circular plate 8. The first support 7 is located between two adjacent guide rails 2 to avoid interference between related components. The first circular plate 8 is installed at the top of the three first support 7, and the plane of the first circular plate 8 is parallel to the plane of the tripod 1, supporting the installation of the three-jaw clamp 9. The three-jaw clamp 9 is installed on the top surface of the first circular plate 8 to position the conical cylinder at the center of the tripod. The three sliders 3 are controlled to slide relative to the three guide rails 2, thereby causing the three C-shaped plates 4 to move closer together or separate.

[0031] This embodiment of the invention provides a tripod welding fixture. Adjusting the three-jaw clamp 9 clamps the conical cylinder of the tripod, thus positioning it. The three pin-shaped posts of the tripod are then placed on three pads 6, respectively, and the three pin-shaped posts engage with the three notches. Subsequently, the three screws 5 are screwed on, and through the interaction between the threads, the top surfaces of the three pin-shaped posts are pressed together, thus positioning them. This results in the three pin-shaped posts being evenly distributed at a certain angular interval around the conical cylinder. Then, under the guiding support of the guide rail 2 and the slider 3, and under the action of external force, the three U-shaped plates 4 can be brought closer together or separated. This allows adjustment of the distance between the three pin-shaped posts and the conical cylinder, enabling the placement of three strip plates of different lengths between the three pin-shaped posts and the conical cylinder for welding. After welding, adjusting the three-jaw clamp 9 again releases the conical cylinder of the tripod. Tighten the three screws (5) again to loosen the three pin-shaped posts of the tripod, thus completing the disassembly of the tripod. The whole process is easy to operate and convenient for welding tripods with three pin-shaped posts at evenly distributed angles.

The disc 11 is mounted on the rotating end of the motor 10 and rotates under the drive of the rotating end of the motor 10. The connecting rods 12 are rotatably connected between the bottom walls of the three U-shaped plates 4 and the edges of the disc 11, respectively, and are used to transmit driving force.

[0033] In this embodiment, the control motor 10 drives the disc 11 to rotate. Then, under the pulling or pushing of the three connecting rods 12, and with the guiding and supporting action of the three guide rails 2 and the three sliders 3, the three C-shaped plates 4 can move closer together or separate. This achieves the automatic position adjustment function of the three C-shaped plates 4, further facilitating welding.
