A tool for opening holes in the bent bottom plate of the lower section of the bell-type transformer oil tank

Abstract

The invention discloses a bell jar type transformer oil tank lower section bending bottom plate opening tooling, comprising an electromagnet base, an electrical control system, a Y-direction moving guide rail, a Y-direction driving gear set, a slider A, and a driving gear rotating around the X-direction , X-direction moving and rotating structure group, X-direction driving gear group, torch clamping device, fixing bolt group and laser pointer, the electromagnet base fixes the device as a whole on the plane of the bottom plate of the lower section, and the electrical control system It is electrically connected with the torch, the Y-direction moving guide rail is provided with a high-precision scale, and the slider A is set on the outside of the Y-direction moving guide rail. The present invention has the advantages of compact overall structure, convenient maintenance, simple and flexible operation. Its own size and positioning size are unified, which greatly improves the quality of opening the installation hole of the pipe joint and the working efficiency.

Description

technical field [0001] The invention relates to the field of hole-drilling devices, in particular to a hole-drilling tool for the lower bent bottom plate of a bell-type transformer oil tank. Background technique [0002] The shape and structure of the workpiece (bending bottom plate of the lower section of the fuel tank) is shown in the attached figure 2 . The range of the bending angle α of the workpiece is 90°-160°, and the hole with a diameter of D (165mm-325mm) is cut after the workpiece is bent. The invention discloses a conventional bell-jar type transformer oil tank lower section bent bottom plate opening tooling, which is a tool for opening holes on the bent bottom plate of the lower section oil tank (especially when the vertical surface and the inclined facade coexist). A drilling device for cutting mounting holes for cooling pipe joints. [0003] The traditional method of cutting the mounting holes for the cooling pipe joints on the lower bending base plate is t...
