演示产品 – 3D five axis laserwelding and cuttingsystem

The Patch Plate Welding Workstation constitutes a critical automated station in the main welding process for the scissor arms of aerial work platforms. Its primary function involves the precise positioning, assembly, and continuous welding of the scissor arm web plates to various attachments—including cover plates, reinforcing patch plates, and ear plate mounts. By ensuring the structural integrity, rigidity, and fatigue life of the scissor mechanism, this workstation serves as the core unit within the entire scissor lift production line for achieving high-efficiency, low-deformation, and high-quality welding.
Ensuring the overall strength, rigidity, and fatigue life of the scissor structure, it serves as the core unit within the entire scissor production line for achieving high-efficiency, low-deformation, and high-quality welding.
 
Main Features
 
  • Achieving Automated Clamping, Positioning, and Welding of Scissor-Arm Plate-Type Parts
  • Complete the welding of the cover plates to the web plates, stiffeners, hinge seats, and other components—specifically, the long straight welds and fillet welds.
  • In conjunction with a positioning mechanism, it enables multi-angle, all-position welding of workpieces.
  • Stably control welding deformation to ensure dimensional consistency and interchangeability of the scissor arms.

Utilizing Tanyi Intelligent’s patented technology, the point laser seam-finding system automatically locates the weld seams on the reinforcement plate. Point laser seam-finding serves as a replacement for traditional contact-based sensing technologies, thereby enabling precise alignment of weld seams; compared to contact sensing, it offers superior efficiency and higher accuracy.

Process Characteristics

  • Controlling Heat Input and Deformation in the Welding of High-Strength Steel Plates for Scissor Arms
  • The weld seams on the backing plates are long and subject to high stress; therefore, they must be continuous, full, and free of porosity and cracks.
  • A symmetrical welding sequence is employed to minimize twisting and angular deformation of the scissor arms.
  • Highly flexible, capable of rapidly adapting to scissor-lift products of varying lengths and thicknesses.
  • Replaces extensive manual welding, enhancing weld seam consistency and production throughput.
