Description

Technical Field

[0001] This invention relates to the field of lifting column welding, and more particularly to a fully automated column welding production line. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure.

[0003] Currently, the production of lift masts generally involves manually placing lift base plate components, such as cable trays and toothed plates, onto the base plate body and spot welding them to shape. Then, manually placing lift mast components, such as pulley supports and chain supports, onto the mast body and spot welding them again. Operators then need to transport the semi-finished base plate and mast to other workstations for full welding of the entire mast. This process constitutes the manufacturing process of the lift mast. Currently, the movement of mast components and semi-finished masts is mainly done manually. This method has low automation, high labor intensity, low work efficiency, and is prone to problems with inaccurate material delivery. Furthermore, the welding of lift masts is mostly done manually. Different welders have different welding skills, resulting in variations in the quality of the welded parts. Due to the significant uncertainty in manual welding, problems such as incomplete welds, weak welds, and porosity can occur, affecting the quality of the lift mast.

[0004] Therefore, it is necessary to design a column welding production line to improve the welding efficiency of columns, reduce the labor intensity of operators, and increase production efficiency. Summary of the Invention

[0060] Base plate assembly welding process -- The first handling mechanism transports the base plate body from the base plate stacking mechanism to the rotary welding platform. Then, the first handling mechanism transports the base plate accessories from the clip mechanism and the irregular part loading mechanism to the base plate body of the rotary welding platform. The first welding mechanism welds them. The welded semi-finished base plate assembly is then transported by the first handling mechanism to the base plate assembly conveyor line for use in the next process.

[0061] Column body conveying process---The column bending machine feeds the material to the top of the automatic feeding line, and the automatic feeding line then conveys the column body to the top of the lifting device.

[0062] The base plate assembly and column are welded together. A lifting device lifts the column body, and a single-axis displacement mechanism at one end of the displacement assembly mechanism clamps one end of the column body for fixation. Simultaneously, a second transport mechanism transports the semi-finished base plate assembly from the rotary welding platform to a double-axis displacement mechanism at one end of the displacement assembly mechanism for fixation. The single-axis and double-axis displacement mechanisms move relative to each other (the displacement assembly mechanism and the single-axis and double-axis displacement mechanisms at both ends are existing technology, common welding positioners, and will not be described in detail here), allowing the column body to align with the base plate assembly. The second welding mechanism performs spot welding on the workpiece. The second handling mechanism picks up the material from the stacking rack and places it on the column accessory positioning mechanism. After precise positioning, the material is picked up and aligned with the workpiece being processed. The second welding mechanism then performs spot welding on the workpiece. After spot welding is completed, the second handling mechanism withdraws. The third welding mechanism and the second welding mechanism simultaneously perform full welding on the workpiece to be processed. After full welding is completed, the lifting device lowers and places the workpiece on the automatic feeding line, which is then conveyed to the rear end of the automatic feeding line. Finally, the workpiece is manually transported to the adjacent area for welding of the column accessories.

[0063] Compared with related technologies, the fully automated column welding production line provided by the present invention has the following beneficial effects:

[0064] This invention is an automated material feeding and welding mode that closely integrates the workpiece processing and production process, and seamlessly connects the processing and production processes. This can reduce manual transportation, significantly reduce the occurrence of workshop hazards, and improve labor productivity, while also reducing the space occupied by stacking.

[0065] The lifting device of the present invention is driven by a synchronous drive component, which enables the symmetrically arranged support mechanism to rise and fall synchronously, which is beneficial to the stable support of the workpiece; the symmetrically arranged limit blocks of the support mechanism are driven by a bidirectional drive component, which can adjust the distance between the two limit blocks to adapt to the support of workpieces of different sizes.

[0066] The magazine mechanism designed in this invention can automatically store and load small parts, avoiding the impact of misaligned small parts on the process; and the designed irregular part loading mechanism facilitates the accumulation of irregular parts that cannot be loaded into the magazine mechanism.
