Polishing device for pressure vessel manufacturing

The invention discloses a polishing device for pressure vessel manufacturing, and relates to the technical field of polishing. The polishing device comprises a workbench and a connecting frame, the top of the workbench is fixedly connected to the bottom of the connecting frame, a supporting plate is fixedly connected to the side face of the connecting frame, a motor is fixedly connected to the top of the supporting plate, a driving rod is fixedly connected to an output shaft of the motor, and a polishing roller is fixedly connected to the end, away from the motor, of the driving rod; a clamping device is arranged on the top of the workbench. Through mutual cooperation of the gravity of the pressure container and components such as a clamping block, a buffer air bag and a supporting rod in the clamping device, the whole device has enough stability, it can be ensured that the situation of shaking or instability cannot occur in the operation process, it can be ensured that equipment has a certain buffer effect d
