Abstract

The invention discloses a welding positioning device for a water heater tank, and belongs to the field of welding positioning devices. The welding positioning device for the water heater tank comprises a rack, clamping devices installed at the two sides of the rack and a support platform located between the two clamping devices. Each clamping device comprises a linear slide rail component, a pressing component and an centering component. The linear slide rail components are arranged on the rack. Slide rail connecting plates are arranged in the pressing components. The slide rail connecting plates are connected with first slide rails in the linear slide rail components in a sliding mode. The centering components are connected with the pressing components in a sliding mode. The centering components at the two sides of the support platform are controlled to clamp with each other through the pressing components. A top pressing device is arranged on the rack to reduce a welding seam. The welding positioning device for the water heater tank has the advantages that the spot welding quality is improved by vertically pressing and horizontally centering, the welding efficiency is high, and the welding positioning device for the water heater tank is suitable for positioning spot welding of the water heater of different sizes.

Description

technical field [0001] The invention relates to the technical field of welding positioning devices, and more specifically relates to a welding positioning device for a water heater inner tank. Background technique [0002] The water heater liner is the device used to store water in the water heater. It must meet the requirements of heat preservation, pressure resistance, no rust, no scale, and no water seepage. The current water heater liner is mainly stainless steel liner, and its advantage is that the liner material is Good, high strength, high temperature resistance, corrosion resistance, stable performance, not easy to rust. Since the water heater liner is difficult to repair once it is damaged, its manufacturing process is very important. As we all know, the stainless steel inner tank is difficult to weld, and the biggest hidden danger is the welding process. In the process flow, the traditional water heater inner tank adopts the end cover welding method, and the inner...
