A multi-station automatic welding method for fan impeller processing

Abstract

The invention provides a multi-station full-automatic welding method for fan wheel processing, comprising the steps of baseplate positioning, baseplate alternating, blade and baseplate assembly, positioning and welding, top cover feeding, welding, tilting welding, and discharging, wherein the blade and baseplate assembly, positioning and welding step refers to clamping a baseplate, pushing blades,and correcting and positioning the blades on the baseplate for welding; the top cover feeding step refers to adjusting horizontalness of a top cover twice and conveying the top cover to a semi-finished blade and baseplate assembly; the welding step refers to performing spot welding on the top cover and blades on a third processing station; the tilting welding step refers to tilting and fully welding a semi-finished top cover and blade welded product subjected to spot welding; the discharging step refers to discharging the finished fan wheel. A fan wheel can be full-automatically welded according to production needs; the traditional welding technique is replaced; welding efficiency, welding quality and welding precision are improved.

Description

technical field [0001] The invention relates to the technical field of industrial welding, and more specifically relates to a multi-station fully automatic welding method for fan impeller processing. Background technique [0002] The fan impeller is a key component of the fan, and whether its structural setting is reasonable directly affects the overall performance of the fan. During the working process, the fan impeller rotates to drive the gas flow, so as to realize the gas discharge. [0003] A fan impeller is a bladed disc consisting of a chassis, blades and a top cover. The chassis and the top cover are arranged in parallel, the number of blades is several and the blades are evenly distributed between the chassis and the top cover, and the two sides of the blades are fixedly connected to the chassis and the top cover respectively. In order to ensure the stability of the connection between the blade, the chassis and the top cover, the blades are usually welded on the c...

AI Technical Summary

Problems solved by technology

However, in actual operation, since there is no positioning device, it is difficult to ensure that several blades are welded to the chassis at the same angle only by manual positioning and operation, and it is also very difficult to place the top cover in an accurate position.

If the coaxial welding of the top cover or the chassis cannot be guaranteed, the positioning of several blades on the chassis will be inconsistent, which will affect the installation, use effect and working performance of the fan impeller in the later stage

In addition, the manual operation will not only greatly increase the labor intensity and difficulty, but also the welding quality depends entirely on the operator's experience, and its welding efficiency and welding quality are relatively low.
