Vertical tool for machining exhaust pipe of high-speed machine and using method of vertical tool

The invention discloses a vertical tool for machining an exhaust pipe of a high-speed machine and a using method thereof.The vertical tool comprises a base, a main pipe, a connecting rod and a plug pin, compared with a traditional vertical tool, the vertical tool can quickly and conveniently complete assembly and installation of parts during use, the exhaust pipe needing to be machined can be stably positioned and supported subsequently, and the machining efficiency is improved. After the machining surface of a certain angle is machined, the numerical control table top and other components can be directly rotated, the exhaust pipe is driven to rotate, then the other machining surface of the exhaust pipe is machined, machining of the whole process is completed after machining is completed, machining precision is more accurate, the overall operation steps are simplified, and the device is simple in overall structure, low in cost and suitable for popularization and application. In addition, production equipment
