The present application discloses an automated detection system and method for butterfly gas cylinder processing technology, belonging to the field of butterfly gas cylinder detection technology. The automated detection system includes a clamping unit for fixing the inner liner of the butterfly gas cylinder, a pressure detection unit, a temperature detection unit and a pressure regulating unit. The automated detection method uses the automated detection system. The pressure sensor of the pressure detection unit is arranged at different positions of the inner liner of the butterfly gas cylinder to realize real-time monitoring of the pressure at different positions. When the pressure difference between the external pressure and the internal pressure of the inner liner of the butterfly gas cylinder exceeds a certain range, the pressure of the inner liner of the butterfly gas cylinder is timely adjusted through the gas channel of the clamping unit by the pressure regulating unit, so that the pressure difference between the external pressure and the internal pressure of the inner liner of the butterfly gas cylinder is kept within a reasonable range, so that the internal and external pressures of the thin-walled butterfly gas cylinder liner are kept in dynamic balance at any same time or any same period during the winding process and the high-temperature curing stage.

The invention discloses a rotatable thermal spraying gun, and relates to the field of thermal spraying, the rotatable thermal spraying gun comprises a frame body, the inner wall of the lower end of the frame body is provided with a shaft core, the upper end of the frame body is provided with a rotating part, the upper end of the rotating part is provided with a rotating flange, and the upper end of the rotating flange is provided with a connecting adapter; a base is installed at the upper end of the connecting adapter, an extension rod is fixedly arranged in the base in a sleeved mode, an offset block is connected to the upper end of the extension rod, and a spray gun is connected to the rear portion of the upper end of the offset block. By arranging the rotating component, the spray gun can be driven to rotate, the situation that a rotating machine rotating shaft is damaged due to huge eccentric torque caused by eccentric rotation of a part is avoided, the situation that internal stress change or tiny deformation of the part is possibly caused by part rotation is avoided, and the machining precision is guaranteed; and through joint cooperation of the rotating component and the offset block, the convex surface of the part can be sprayed, and the use scene and the process applicability of the equipment are expanded.

This utility model discloses a positioning mechanism for spray painting, belonging to the field of spray painting positioning. It includes a placement frame, with a conveying mechanism rotatably mounted inside the frame. Positioning structures are installed on both sides of the placement frame, and a telescopic rod is installed inside the clamping surface of each positioning structure. An auxiliary plate is installed at the moving end of the telescopic rod. The telescopic rod, auxiliary plate, and adjustment mechanism work together. The telescopic rod's moving end extends the auxiliary plate upwards. Based on the workpiece's weight distribution and bottom shape, the support height and position of the auxiliary plate are adjusted to ensure precise contact between the auxiliary plate and the bottom of the workpiece. This effectively disperses the lateral clamping force on the workpiece, preventing minor deformation due to the workpiece's own weight or concentrated clamping force. The adjustment mechanism works synchronously, adaptively filling the gap between the positioning structure and the workpiece's side, enhancing the tightness of the side clamping, thereby preventing workpiece deformation and improving the accuracy of subsequent spray painting.

According to the machining method of the seamless thick-wall conical pipe for the chemical equipment, zirconium alloy raw materials are accurately controlled, the seamless thick-wall conical pipe is manufactured through a series of machining steps such as vacuum melting, cogging, saw cutting, blank manufacturing and rolling on the basis of the zirconium alloy raw materials, multiple heat treatment processes are executed in the machining process, the mechanical internal stress of products is effectively reduced, and the product quality is improved. Particularly, the design of a reaming die mandrel and a driving rotating shaft is adopted after forging in the machining process, so that the large head and the small head of the conical workpiece rotate at the same angle and speed in the reaming process, and finally better roundness and uniform wall thickness are obtained; and a product with a uniform structure is obtained.
