The invention discloses a tool for cutting circular holes, including a bottom plate with an annular base at the end, supporting rods at both sides of the annular base, sliding rods at the upper end of the supporting rods, the sliding rods coinciding with the central axis of the annular base, sliding connecting sliding blocks on the sliding rods, and screw on the sliding blocks. The lower end of the slide block is provided with a lower connecting block, and one side of the lower connecting block is provided with a circular cutting gun positioning block. The circular wall of the circular base is provided with a rotating block uniformly distributed along the center of the circle. The rotating block is concave and the inner side is provided with a roller. The roller is located at the upper end of the circular base, and the rotating block is arranged on the circular center. A ring-shaped supporting plate is fixed on one side of the block toward the center of the circle of the ring-shaped base. The tool has simple structure and easy operation. It is convenient to cut round holes of different sizes in the middle of the top cover of the water tank. The circular holes after cutting have high contour and are convenient for the embedding of the following manhole cover.
【技术实现步骤摘要】
一种圆孔切割用的工装
本专利技术涉及水箱加工工装领域,特别涉及一种圆孔切割用的工装。
技术介绍
不锈钢圆形水箱的顶部通常开有人可以进入的圆孔,便于工人进入水箱内清洗维修,工人对水箱顶盖开孔的常规方法是在顶盖上先用记号笔划出人孔的外轮廓,然后用割枪沿着划线将人孔部分割去,为了保证人孔盖能顺利安装,通常需对人工切割的圆孔处进行二次打磨,使人孔盖能嵌入所开圆孔中,这种开孔方式效率低,精度差。
