A maintenance-friendly laser cutting machine for manhole cover processing

Abstract

The invention discloses a laser cutting machine for manhole cover machining and convenient to maintain. The laser cutting machine comprises a rack body. A working table is movably connected to the upper surface of the rack body. Supports are symmetrically connected to the positions, on the two sides of the working table, of the rack body. The adjacent sides of the supports are symmetrically provided with guide sliding grooves. The upper ends of the supports are jointly connected with a top plate. A hydraulic cylinder is installed on the upper surface of the top plate. The output end of the hydraulic cylinder penetrates through the top plate and is connected with a driving motor. According to the laser cutting machine for manhole cover machining and convenient to maintain, the hydraulic cylinder controls a rotary disc to move up and down, a limiting rod and a limiting slider achieve auxiliary and guide effects, the height positions of laser cutters are convenient to adjust, maintenancework can be conducted on the equipment easily, the rotary disc is provided with an adjusting sliding groove, the distance between the two laser cutters is adjusted through the adjusting sliding groove, the laser cutting machine is suitable for cutting of manhole covers of different diameters, wide in use range, convenient to use and easy to maintain, and cost is lowered.

Description

technical field [0001] The invention relates to the technical field of manhole covers, in particular to a maintenance-friendly laser cutting machine for manhole cover processing. Background technique [0002] Manhole covers are used to cover the defenses on the road or deep wells at home to prevent people or things from falling. They are generally divided into round and square. In terms of road administration in urban areas, round is generally used because round manhole covers are not easy Tilting can better protect the safety of pedestrians and vehicles. For the processing of manhole covers, the traditional method adopts the method of casting molding, but this method has many processes, and the demand for casting molds is large, and it takes up a lot of space. [0003] Chinese patent CN208117037U discloses a new type of automatic laser processing device, including a manhole cover laser cutting machine. The lower part of the manhole cover laser cutting machine is provided wi...

AI Technical Summary

Problems solved by technology

[0004] Although this application solves the problems in the background technology to a certain extent, the height of the cutter in this application is not adjustable, and the workbench structure is simple. During laser cutting, the laser is easy to damage the workbench, affecting the flatness of the workbench, giving It is more difficult to maintain the workbench in the later stage
