Device and technology of automatic impeller indexing weld

Abstract

The invention discloses a device and a technology of automatic impeller indexing weld, and belongs to the technical field of impeller weld in the fan industry. The device controls walk steps of a splitting motor by setting a splitting procedure of a controller, and can equally divide an impeller at any angle through a decelerating machine. A further improvement is flip type weld, and the flip type weld is characterized by instructing a flipping motor to drive a decelerating mechanism to achieve flipping at any angle by setting a flipping procedure of the controller, and thereby facilitating reinforced welding. The weld technology includes: firstly clamping an impeller rear disc and fastening, and fixing blades for spot welding; then using the device for indexing weld on each blade, and placing an impeller front disc and fastening; afterwards turning over a working table to a target position and then performing indexing weld reinforcing on each blade; and finally turning over the working table to an initial point to finish the weld. The device and the technology can achieve equally dividing the impeller accurately, are simple and convenient to manipulate, and enable the weld to be stable and beautiful.

Description

technical field [0001] The invention belongs to the technical field of impeller welding in the fan industry, and in particular relates to a welding device and process for determining the positions of blades by dividing the impeller into equal parts at any degree. Background technique [0002] At present, in the fan industry, the impeller is the key component of the fan, and the welding quality and precision of the blades are particularly important. The traditional welding method is still to fix the impeller rear plate on the welding mold, use a compass ruler to mark the line manually or use a fixed The indexing plate of the scale is used to determine the position and angle of the blade, but the number, angle and direction of the impeller blades are different due to the different uses of the fan. When the number of blades is different, the indexing plate with different scales needs to be replaced, so that the traditional indexing welding method The speed is slow, there is no ...

[0002] At present, in the fan industry, the impeller is the key component of the fan, and the welding quality and precision of the blades are particularly important. The traditional welding method is still to fix the impeller rear plate on the welding mold, use a compass ruler to mark the line manually or use a fixed The indexing plate of the scale is used to determine the position and angle of the blade, but the number, angle and direction of the impeller blades are different due to the different uses of the fan. When the number of blades is different, the indexing plate with different scales needs to be replaced, so that the traditional indexing welding method The speed is slow, there is no homogeneity in mass production, and the impeller is placed in a flat position during welding. Welding spatter will easily affect the appearance and cause false welding. There are defects such as uneven welding, inconsistent angles, and large welding deformation, which makes the impeller When doing static balance and dynamic balance, the deviation is large and unstable, which directly affects the performance of the fan
