Welding and fixing device for fixing seat of axial flow fan

Abstract

The invention discloses a welding and fixing device for a fixing seat of an axial flow fan. The welding and fixing device comprises a base, transverse rotating shafts, a swing driving mechanism, a rotating seat, a vertical rotating shaft, a rotary driving mechanism and a fixed head, the base is U-shaped and fixedly connected with the ground, two transverse rotating shafts are symmetrically arranged on the two sides of the upper end of the base through a bearing seat, the swing driving mechanism is arranged in the base, the output end of the swing driving mechanism is fixedly connected with oneof the transverse rotating shafts, the two ends of the rotating seat are correspondingly and fixedly connected with the inner ends of the transverse rotating shafts, the vertical rotating shaft is arranged at the top end of the rotating seat through the bearing seat, the rotary driving mechanism is arranged in the rotating seat, the output end of the rotary driving mechanism is fixedly connectedwith the vertical rotating shaft, the fixed head is used for fixing a fan blade fixing seat, and the fixed head is fixedly connected to the top end of the vertical rotating shaft. The welding and fixing device has the advantages of simple structure, wide applicability, good use effect and the like.

Description

technical field [0001] The invention relates to the technical field of axial flow fan production equipment, in particular to a welding and fixing device for a fixed seat of an axial flow fan. Background technique [0002] Axial flow fans are very widely used, that is, the airflow in the same direction as the axis of the fan blades, such as electric fans, air conditioner external fans are axial flow fans. It is called "axial flow" because the gas flows parallel to the shaft of the fan. Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements. Axial fans hold the position and move the air. The axial flow fan is mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high. [0003] The fan blade part is mainly composed of a fixed seat and a blade. During production, the blade needs to be accurately welded to the fixed seat. Since the joint is an irregular curve, it is usuall...

AI Technical Summary

Problems solved by technology

[0003] The fan blade part is mainly composed of a fixed seat and a blade. During production, the blade needs to be accurately welded to the fixed seat. Since the joint is an irregular curve, it is usually welded by a six-axis manipulator, but in During the welding process, the movement of the six-axis manipulator is limited. For irregular welding curves, the welding is difficult and the programming is more complicated; at the same time, due to the different specifications of the axial flow fans, the specifications of their fixing seats are also different. Fixed tooling, it is difficult to achieve a comprehensive fixation
