The upper end of the left side of the base is fixedly connected with the laser control robot, the top end of the laser control robot is movably connected to a mechanical arm, the front end of the mechanical arm is movably connected to a laser beam output device, a laser is arranged on the left side of the base, the laser is connected to the laser beam output device through an optical fiber, the center of the upper end of the base is movably connected to a rotary worktable, the left side of the upper end of the rotary worktable is fixedly connected to a positioning block, the right side of the positioning block is provided with a ultra-large plastic inspection well seat, and an assembly robot is fixedly connected with the right side of the upper end of the base. The device adopts a modular multi-layer annular ring block and a combined well seat bottom plate connection structure, adopts a laser transmission welding method, is convenient and flexible to operate, has high welding efficiency, reduces the design and manufacturing cost of a injection mold and the difficulty of the injection molding process, and achieves the miniaturization of the injection mold and injection molding equipment and flexible and modular production of ultra-large plastic inspection well seats.

Description

technical field [0001] The invention relates to the field of forming and processing of extra-large plastic inspection wells, in particular to a laser welding combined forming device and method for well seats of extra-large plastic inspection wells. Background technique [0002] In the construction of municipal water supply and drainage pipe network systems, the market demand for extra-large plastic inspection well bases with diameters and heights greater than 1.5 meters is increasing. The well bases undertake sub-pipes and well chambers, and carry Due to the lateral pressure of the surrounding soil and the impact pressure of road vehicles, the well base must have strong compressive, tensile and bending strength. The length and width of the plate are relatively large, and the wall thickness of the well base reaches 15-20mm. [0003] Since the diameter and height are greater than 1.5 meters, one-time overall injection molding has been difficult to meet the processing requirem...
