Abstract

The invention discloses a water heater liner welding fixture used for spot welding positioning, and belongs to the field of welding and positioning devices. The welding fixture comprises a support, clamping devices installed on two sides of the support and a supporting table located between the two clamping devices; the clamping devices are oppositely installed and comprise compressing components and centering components, the compressing components are internally provided with sliding rail connecting plates, and the sliding rail connecting plates are fixedly connected with a workbench; the centering components are slidingly connected with the compressing components, and the centering components arranged on two sides of the supporting table are controlled by the compressing components to carry out mutual clamping, and a top compressing device is arranged on the support to reduce welding gaps. According to the water heater liner welding fixture, by means of longitudinal compressing and transverse centering, the spot welding quality is improved, the welding efficiency is high, and the welding fixture is suitable for position spot welding of water heater liners with different sizes.

Description

technical field [0001] The invention relates to the technical field of welding positioning devices, and more specifically relates to a water heater liner welding tool for spot welding positioning. Background technique [0002] The water heater liner is a device used to store water in a water heater. It must meet the requirements of heat preservation, pressure resistance, no rust, no scale, and no water seepage. The stainless steel liner is an important part of the water heater liner. Its advantages are The liner has good material, high strength, high temperature resistance, corrosion resistance, stable performance, and is not easy to rust. Because the inner tank of the water heater is difficult to repair once it is damaged, its manufacturing process is also very important. However, the stainless steel inner tank is difficult to weld, and the biggest hidden danger is the welding process. In the process flow, the welding method of the end cover of the traditional solar water h...
