Problems solved by technology
[0004] For the welding of the volute, the existing welding process uses hand-held hoardings and side plates, which are fixed by spot welding, and then welded by hand. This process is labor-intensive, and workers are near the electrodes for a long time. Radiation will cause bodily harm to workers. , low efficiency, unsightly welds and low production efficiency

The invention discloses a volute welding and locating device. The volute welding and locating device comprises a locating and clamping support, an inner supporting mechanism connected with the locating and clamping support and used for locating and tightly tensioning the inner wall of a welded volute and an outer pressing mechanism connected with the locating and clamping support and used for pressing the outer wall of the welded volute. An electrode with the shape matched with that of the inner wall of the welded volute is arranged on the inner supporting mechanism. According to the volute welding and locating device, the welded volute is firstly subjected to spot welding fixing and then is fixed to the volute welding and locating device, welding and rotating can be achieved at the same time, and therefore automatic machining is achieved; the labor intensity of workers is reduced, and the production efficiency is improved; and the welding line is attractive and uniform, the strength of the welding line is large, connecting is stable, and the volute welding and locating device can be widely used for locating and clamping of the volute.
Description
technical field [0001] The invention relates to a welding device, in particular to a positioning device for processing a volute. Background technique [0002] Seam welding means that the workpiece passes between two rotating disc electrodes (roller discs) to form a continuous weld seam where the welding spots overlap before and after. The weldment is assembled into a lap joint or a diagonal butt joint and placed between the electrodes of the two rollers, and moves relative to the workpiece. The roller presses the weldment and rotates, and continuously or intermittently transmits electricity to form a continuous weld. [0003] The air duct volute of the range hood includes a coaming plate, side plates located on both sides of the coaming plate, and support blocks arranged on the side plates. [0004] For the welding of the volute, the existing welding process uses hand-held hoardings and side plates, which are fixed by spot welding, and then welded by hand. This process is l...
