An automatic welding equipment for multi-blade fan impeller

Abstract

The invention provides an automatic welding device for a multi-blade fan impeller, which belongs to the technical field of machinery. It solves the problems of low production efficiency and poor welding quality of the existing multi-wing fan impeller. This equipment includes a welding robot, a frame, a tooling fixture, a stocker and a clamping device. The tooling fixture includes a column 1 and a column 2 fixedly connected to the frame, and a chuck 1 and a clamp are arranged between the column 1 and the column 2. Plate 2, the frame is provided with a slide rail for the column 2 to move left and right, and the frame is also provided with a cylinder 1 that can push the column 2 to move on the slide rail. The stocker and the frame are fixed through the bottom plate, and the bottom plate There is a slide rail for the stocker to move left and right on the top, and a cylinder 2 that can push the stocker to move on the slide rail is also provided on the bottom plate. Jaws, clamping cylinder and cylinder three, the clamping cylinder controls the opening and closing of the jaws. The invention has the advantages of high production efficiency, good welding quality and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to welding equipment, in particular to an automatic welding equipment for multi-blade fan impellers. Background technique [0002] In addition to the motor and volute, the important part of the fan is the impeller. The welding quality of the impeller parts not only affects the air volume, efficiency and life of the fan, but also affects the stability of the fan's motion balance, vibration and noise. Therefore, the quality of the impeller plays a very important role in the product. Due to the advantages of many blades, stable movement, small vibration, low noise, large flow rate and long life, the multi-wing fan is favored by the market and praised by consumers. [0003] The existing multi-blade fan impeller welding process is to manually spot-weld the blades on the wheel disc, and perform integral welding after spot-welding the wheel cover. Although the spot welding of the blade on...

AI Technical Summary

Problems solved by technology

Although the spot welding of the blade on the wheel disk is simple and efficient, the blade will tilt to both sides and cannot be perpendicular to the wheel disk. In addition, when the subsequent wheel cover is welded, in order to ensure the tight fit between the wheel cover and the blade, an axial force, but it will increase the inclination angle of the blade

Therefore, manual correction is still difficult to meet the design requirements

The other is manual spot welding. The level of welding technology also has a great influence on the welding quality of the impeller. The product quality is uneven, which seriously affects the product quality.
