Abstract
Description
Technical Field
[0001] This utility model relates to the field of stud welding technology, specifically to a gantry-type stud welding device. Background Technology
[0002] Stud welding involves welding a column-shaped stud onto a flat plate using a high current. The area of the flat plate must be larger than the welding area of the stud. This reliable and mature technology is used for welding studs, heat sink studs, steam unit screws, and bolts to steel structures. Automated welding can be achieved when the workpiece is fixed or the operating environment is relatively flat.
[0003] At the steel structure production base, I-beams and large tank components that are over 2 meters high are currently welded by welders standing on the steel beams using ladders. Manual welding is slow, and welders have to carry long electrical wires, which is not good for their safety and can easily lead to accidents. In addition, it is not economically efficient. Utility Model Content
[0004] This invention provides a gantry-type stud welding device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A gantry-type stud welding device includes a tracked moving mechanism, a support frame, and a transverse support member. The tracked moving mechanism and the support frame are both located on both sides of the transverse support member. The support frame is connected to the tracked moving mechanism, and the transverse support member is connected to the support frame. A welding assembly is connected to the transverse support member to weld workpieces below it. By adopting this technical solution, the transverse support member, with support frames and the tracked moving mechanism at both ends, forms a freely movable gantry. The welding assembly allows for welding of the workpiece within the gantry.
[0007] Furthermore, the track moving mechanism, support frame, and lateral support are detachably connected. By adopting the above technical solution, the detachable connection facilitates transportation and installation, and the support frame height can be adjusted according to the object being welded.
[0008] Furthermore, the welding assembly includes a robotic arm, a stud welding torch, a power supply mechanism, and an electrical control box for controlling the robotic arm. Both the robotic arm and the power supply mechanism are connected to the transverse support, and the stud welding torch is connected to the end of the robotic arm furthest from the transverse support. By adopting the above technical solution, the robotic arm has a high degree of freedom, welding is convenient, and automation is high.
[0009] Furthermore, the transverse support is equipped with a stud storage assembly for providing studs. The stud storage assembly includes a stud ring assembly machine and a stud magazine, with the output end of the stud ring assembly machine connected to the input end of the stud magazine. By adopting the above technical solution, studs and rings only need to be fed into the stud ring assembly machine, which can then input the studs with the rings into the stud magazine. The robotic arm can then move the welding torch above the stud magazine to retrieve the studs.
[0010] Furthermore, slide rails are provided on both sides of the transverse support member, and sliders are provided on the slide rails. The sliders are connected to the sliders on the long sides of the transverse support member and cover the top of the transverse support member. A robotic arm mounting base is connected to the upper end of the slider, and the robotic arm is mounted on the robotic arm mounting base. The stud welding gun is connected to the free end of the robotic arm. By adopting the above technical solution, the robotic arm can slide on the transverse support member, increasing the welding range.
[0011] Furthermore, an L-shaped hook is suspended at the lower end of the transverse support member, with the upper end of the L-shaped hook fixed to the lower end of the transverse support member, and the stud storage assembly fixed to the lower end of the L-shaped hook. By adopting the above technical solution, the stud storage assembly is set at the lower end of the transverse support member, which facilitates the welding torch in welding and removing studs from the workpiece below the transverse support member.
[0012] Furthermore, the lateral support member has a support plate and a support rod on the side away from the robotic arm. The power supply mechanism and control box are located on the support plate, and a mounting groove is connected to the support rod. A tank chain for installing electrical wires is installed in the mounting groove. By adopting the above technical solution, the tank chain stores and protects the electrical wires.
[0013] Furthermore, the robotic arm, power supply mechanism, and stud reserve assembly are all fixedly connected to the transverse support, and the electrical control box is fixed to one side of the support frame. By adopting the above technical solution, the robotic arm is relatively fixed, and the structure is stable and compact.
[0014] Furthermore, the support frame includes an upper support frame and a lower support frame. The lower end of the lower support frame is detachably connected to the track moving mechanism, and the upper end of the lower support frame is detachably connected to the lower end of the upper support frame. The upper end of the upper support frame is detachably connected to a transverse support member. The lower support frame is H-shaped and vertically connected to the track moving mechanism. The upper support frame is composed of two parallel rods and a connecting rod / cross rod, and the upper support frame is inclined. By adopting the above technical solution, the detachable connection facilitates transportation and installation, and the height of the support frame can be adjusted according to the object being welded.
[0015] Furthermore, the transverse support is equipped with a lifting frame for hoisting the transverse support and welding components, and a robotic arm guardrail for protecting the robotic arm. The lifting frame is a trapezoidal columnar frame structure, and the robotic arm guardrail is generally arc-shaped. By adopting the above technical solution, the lifting frame facilitates the hoisting of the transverse support onto the connecting frame, and the arc-shaped robotic arm guardrail facilitates the rotation of the robotic arm.
