Abstract

The invention discloses an automatic welding tool for straight splicing slits of base plates of dump trucks, which comprises a material-placing operation platform and an automatic welder gun, wherein the automatic welder gun is arranged on the material-placing operation platform, and the automatic welder gun is electrically connected with a welding power supply; and the automatic welding tool also comprises a PLC (programmable logic controller) and a traveling mechanism, wherein the traveling mechanism controls the automatic welder gun to transversely and longitudinally move along the material-placing operation platform, and the PLC is electrically connected with the traveling mechanism. The servo drive traveling mechanism is controlled through the PLC so as to realize the automatic stable traveling of the automatic welding tool. The automatic welding of straight splicing slits of base plates of dump trucks is realized, the manual welding is replaced, and the welding quality and the welding efficiency are improved. The parameters such as welding speed, welding length and the like can be changed through changing a PLC program so as to meet the automatic welding requirements of carbon steel plates with different thicknesses; and through replacing the types and models of welders or the types and models of welding wires, the welding of straight splicing slits of base plates of dump trucks made of different materials can be realized.

Example Embodiment

[0016] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments;

[0017] Such as figure 1 As shown, a vertical seam automatic welding tool for splicing the bottom plate of a dump truck includes a discharge workbench 1, an automatic welding machine welding gun 2, an automatic welding machine welding gun 2 and a welding power source 3 electrically connected, and also includes a PLC programmable controller 8 and a control The walking mechanism 4 of the welding gun 2 of the automatic welding machine that moves horizontally and longitudinally along the discharge table 1, and the PLC programmable controller 8 is electrically connected to the walking mechanism 4. Among them, the traveling mechanism 4 is composed of a horizontal servo-driven traveling mechanism 41 and a longitudinal servo-driven traveling mechanism 42. The PLC programmable controller 3 is electrically connected with the horizontal servo-driven traveling mechanism 41 and the longitudinal servo-driven traveling mechanism 42 respectively, and the welding gun 2 of the automatic welding machine Set on the lateral servo-driven traveling mechanism 41.

[0018] The longitudinal servo-driven traveling mechanism 42 consists of a longitudinal drag chain 421 that provides driving force for the traveling gear assembly 422, a traveling gear assembly 422, and rack guide rails laid on both sides of the unwinding table 1 along the length of the unwinding table 1 423, the walking gear assembly 422 meshes with the rack rail 423. Both sides of the unwinding workbench 1 are provided with longitudinal towline troughs 5 matingly connected with the longitudinal towline 421, while the two sides of the unwinding workbench 1 are also laid with bolsters 6, and rack guide rails 423 are laid on the bolsters 6. .

[0019] The horizontal servo-driven traveling mechanism 41 is composed of a longitudinal moving frame 411 that straddles the unwinding table 1 and a horizontal drag chain 412 arranged on the longitudinal moving frame 411. The welding gun 2 of the automatic welding machine is connected to the horizontal drag chain 412, and the longitudinal moving frame 411 Both ends are fixed with the traveling gear assembly 422 of the longitudinal servo-driven traveling mechanism 4. When the longitudinal servo-driven traveling mechanism 42 moves along the rack rail 423, it also drives the longitudinal moving frame 411 on the upper surface of the unwinding table 1. Move along the straight seam 7 of the bottom of the dump truck. One side of the unwinding workbench 1 is close to the wall 9, and a power control box 10 connected to the PLC programmable controller 8 is provided on the wall 9. An equipment parking area 11 is provided at the feeding port of the unwinding workbench 1.

[0020] When in use, the operator stands in front of the PLC programmable controller 8, writes the PLC program, inputs the program into the PLC programmable control system, and controls the horizontal servo-driven traveling mechanism 41 to align the automatic welding gun 2 with the bottom plate splicing straight seam 7 , The longitudinal servo-driven traveling mechanism 42 drives the longitudinal moving frame 411 to move steadily along the longitudinal direction. At the same time, the welding gun 2 of the automatic welding machine starts arc welding along the longitudinal longitudinal seam, thus realizing the automatic welding of the dump truck bottom plate splicing longitudinal seam, instead of manual welding, improving Welding efficiency and welding quality.

[0021] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by those of ordinary skill in the art within the essential scope of the present invention shall belong to The protection scope of the present invention.
