Description

Technical Field

[0001] The utility model relates to a positioning device, in particular to a cylinder barrel welding positioning device, belonging to the technical field of oil cylinder processing. Background Art

[0002] A hydraulic cylinder is a device used to generate linear motion. It uses hydraulic pressure to push the piston to work. It mainly uses the liquid to generate pressure inside the cylinder, thereby pushing the piston to move linearly. When the hydraulic oil enters the cylinder from the hydraulic pump through the hydraulic pipeline, the hydraulic pressure acts on the piston, causing it to generate thrust or pull. By controlling the valves in the hydraulic system, the hydraulic cylinder can be controlled to adjust the size and direction of the thrust or pull.

[0003] The cylinder barrel is one of the important components of the hydraulic cylinder. It is usually made of steel and has high strength and corrosion resistance. Welding is one of the important processing steps in the cylinder barrel processing and production process. It mainly uses welding to fix the hydraulic interface / nozzle in the hole opened on the outer wall of the cylinder barrel.

[0004] China's publicly authorized invention: CN213497465U discloses a welding positioning tool for the joint of the oil cylinder barrel, which is positioned and installed on the base through a V-shaped positioning block and a vertical adjustment shaft; the vertical adjustment shaft is positioned on one side of the V-shaped positioning block; the adjustment block is positioned and installed on the vertical adjustment shaft; the horizontal positioning shaft is positioned on the adjustment block; the oil cylinder barrel is placed horizontally in the V-shaped groove of the V-shaped positioning block; the transverse interface of the right-angle joint is axially connected with the horizontal positioning shaft, and the vertical interface of the right-angle joint is relatively positioned with the interface of the oil cylinder barrel. This application adjusts the outer diameter of the cylinder barrel and the height of the joint height adjustment block on the vertical adjustment shaft, aligns the oil hole on the cylinder barrel with the through hole of the right-angle joint, connects the horizontal positioning shaft to the thread of the right-angle joint, presses and spot welds it for positioning; realizes the relative positioning and processing of the right-angle joint and the axis angle of the cylinder barrel, greatly reduces the welding error between the oil cylinder barrel and the right-angle joint, shortens the positioning time, and greatly improves the product quality.

[0005] However, although the device can align the oil hole on the cylinder barrel and the through hole of the right-angle joint, thereby reducing the welding error between the cylinder barrel and the right-angle joint, the hydraulic interface / oil nozzle of large cylinder barrels are mostly straight barrel type, and the device is not suitable. Moreover, the V-shaped positioning block used in the device cannot guarantee the stability of the cylinder barrel during welding, and the operation is more inconvenient when the cylinder barrel needs to be rotated to adjust the cylinder barrel angle. Therefore, a cylinder barrel welding positioning device is proposed. Utility Model Content
