Description

Technical Field

[0001] The utility model belongs to the technical field of pressure tank production, and in particular relates to a welding positioning tool for pressure tank body legs. Background Art

[0002] A pressure tank is a pressure vessel used to store and process gases or liquids. It primarily utilizes the different properties of water and gas, using a process of gas compression and expansion to balance the water volume and pressure in the system. When the water pressure in the system increases, the gas in the pressure tank is compressed, storing additional water. When the water pressure drops, the gas expands, releasing the stored water, thereby maintaining a stable system pressure. This operating principle not only helps prevent frequent opening of the safety valve and frequent replenishment of the automatic water supply valve, but also effectively balances water volume and pressure, preventing excessive pressure fluctuations in the system. The pressure tank operates automatically, minimizing pressure fluctuations, ensuring safety, reliability, energy conservation, and economical efficiency.

[0003] The production of a pressure tank primarily involves welding the tank body and the end caps. Once the tank body and end caps are welded, a leg is welded to one of the end caps to complete the pressure tank. To ensure the stability of the pressure tank, the leg's position and angle on the end cap are fixed, and production must be strictly carried out in accordance with the pressure tank's design drawings. The current production process often involves a welder holding the leg with one hand and a welding torch with the other to secure the leg to the end cap. This method is inefficient and can sometimes injure the welder from sparks from the torch and leg, posing a safety hazard.

[0004] Therefore, it is necessary to design a positioning tool that is easy to operate and improves welding quality and welding efficiency to solve the current technical problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a welding positioning tool for the legs of a pressure tank body, which solves the problems of low positioning accuracy and welding efficiency between the legs and the head of the pressure tank.

[0006] The technical solution of the utility model is: a welding positioning tool for the tank legs of a pressure tank, comprising a horizontally arranged base plate, a plurality of rotating rollers arranged side by side on the base plate, the base plate on one side of the rotating roller is fixedly connected to a vertically arranged vertical plate, the vertical plate is fixedly connected to a horizontally arranged tightening cylinder, the fixed end of the tightening cylinder is fixedly connected to the vertical plate, the piston rod end of the tightening cylinder passes through the vertical plate and the end is fixedly connected to a tightening suction cup, the base plate on the other side of the rotating roller is fixedly connected to a vertically arranged support plate, the support plate is fixedly connected to a horizontally arranged clamping cylinder, a linear slide rail is provided between the support plate and the rotating roller, a slider is slidably connected to the linear slide rail, the upper end of the slider is fixedly connected to an L-shaped mounting plate, the piston rod end of the clamping cylinder is fixedly connected to the L-shaped mounting plate, and a positioning shaft is provided on the L-shaped mounting plate.

[0007] Preferably, the L-shaped mounting plate is fixedly connected to a vertically arranged fixing plate, and the piston rod end of the pressing cylinder is fixedly connected to the fixing plate.
