Problems solved by technology

[0003] The fan is one of the important parts in the range hood. The fan casing of the existing range hood can be molded, or the fan casing can be divided into several sheets, and then the sheets are welded and fixed. However, the existing When the plates are welded and fixed, deviations between the two plates are likely to occur, which will affect the quality of the fan casing and shorten the service life of the fan casing

Abstract

The invention discloses a fixed-position welding device used for a range hood fan shell and a welding method thereof. The device comprises a supporting table, a clamping assembly and a mould assembly.The clamping assembly comprises a clamping press block, an X-direction regulating mechanism, a Y-direction regulating mechanism and a Z-direction regulating mechanism. The X-direction regulating mechanism comprises a rodless cylinder. The Y-direction regulating mechanism comprises an adjusting screw rod and an adjusting hand wheel, the adjusting hand wheel is located at the top end of the adjusting screw rod, a slide block is arranged on the adjusting screw rod, and the clamping press block is hinged and fixed to the slide block. The Z-direction regulating mechanism comprises an adjusting cylinder and a fixing support. The mould assembly comprises an arc-shaped mould, a fixing sleeve and a fixing rod. The welding method comprises the following steps that (1) the mould assembly is mounted;and (2) the fan shell is welded and machined. The fixed-position welding device is ingenious and reasonable in structural design, by pressing and positioning sheets, the attaching levelness between every two adjacent sheets is guaranteed, accordingly, the welding quality of subsequent sheets is improved, the welding precision is improved, the quality of the fan shell is improved, and the servicelife of the fan shell is prolonged.

Description

technical field [0001] The invention relates to a positioning welding device and a welding method for a range hood fan casing. Background technique [0002] Range hood, also known as range hood, is a kitchen appliance that purifies the kitchen environment. It is installed on the top of the kitchen stove, which can quickly take away the waste burned by the stove and the harmful oil fume produced during the cooking process, and discharge it outside, reduce pollution, purify the air, and have the safety guarantee function of anti-virus and explosion-proof. Range hoods need to be cleaned regularly. Simple cleaning cannot remove oil stains. To clean range hoods, professional cleaning agents must be used for cleaning. [0003] The fan is one of the important parts in the range hood. The fan casing of the existing range hood can be molded, or the fan casing can be divided into several sheets, and then the sheets are welded and fixed. However, the existing When the plates are bond...
