Problems solved by technology

[0002] The welding process between the fan blade and the rotor and the position of the fan blade relative to the rotor directly affect whether the fan blade rotor can work normally, so when welding the fan blade and the rotor, it is necessary to ensure its position before welding, but in actual production In order to ensure its welding position accuracy, it is necessary to increase redundant capital investment in the production process, which increases the production cost, and it is easy to cause poor welding between the fan blade and the rotor during the production process, resulting in product scrap

Embodiment 1

[0010] Embodiment 1: refer to Figure 1~2 . Blade and outer rotor welding tool, fan blade and outer rotor welding tool is composed of base plate 4, outer rotor positioning seat 3, fan blade positioning template 6 and positioning rod 5, outer rotor positioning seat 3 is located in the center of the bottom plate 4, 3 pieces Or 4 or 5 or more fan blade positioning templates 6 are equidistantly arranged around the outer rotor positioning seat 3 and supported by multiple positioning rods 5, that is to say, the matching height of the fan blade positioning template 6 and the outer rotor is completely It is supported by a plurality of positioning columns 5 with different heights. Outer rotor positioning seat 3 is made of central positioning rod seat 8, central positioning rod 2 and compression nut 1, and the lower end of central positioning rod 2 is positioned on the central positioning seat, and the upper end is shaped on thread and cooperates with compression nut 1. The lower end ...

Embodiment 2

[0011] Embodiment 2: On the basis of Embodiment 1, the fan blade and outer rotor welding method, which includes the fan blade and outer rotor welding tool and the outer rotor motor described in claims 1 to 4 above, the outer rotor motor center axis hole vertical It is directly sleeved on the center positioning rod 2 of the outer rotor positioning seat 3, the lower end surface of the outer rotor is in contact with the surface of the center positioning rod seat 8, and the upper end surface is compressed by the compression nut 1, and the wind blades are placed on the blade positioning template 6 in turn. The template surface is consistent with the template surface, the lower end surface of the fan blade is in contact with the limit rod 7, the welding surface is in contact with the peripheral surface of the outer rotor, and then the welding surface of the fan blade is welded to the peripheral welding surface of the outer rotor. That's it.

Abstract

The invention relates to a fan blade and outer rotor welding tool and a welding method. The fan blade and outer rotor welding tool is composed of a base plate, an outer rotor positioning seat, a fan blade positioning template and a positioning rod. The outer rotor positioning seat is located in the center of the base plate. Three or more blade positioning templates are arranged equidistantly around the outer rotor positioning seat and are supported by positioning rods. Advantages: First, it not only achieves precise distribution and reliable welding of the angular spacing between multiple blades and the outer rotor, but also achieves accurate, convenient and fast positioning, simplifies the welding process, reduces manufacturing costs, and improves welding efficiency; second, the structure The design is novel, unique, simple, and convenient for automated manufacturing.

Description

technical field [0001] The invention relates to a fan blade and an outer rotor welding tool and a welding method for rapid positioning welding of the fan blade and an outer rotor, and belongs to the field of fan blade and outer rotor welding tool and welding method manufacturing field. Background technique [0002] The welding process between the fan blade and the rotor and the position of the fan blade relative to the rotor directly affect whether the fan blade rotor can work normally, so when welding the fan blade and the rotor, it is necessary to ensure its position before welding, but in actual production In order to ensure the welding position, it is necessary to increase redundant capital investment in the production process, which increases the production cost, and it is easy to cause poor welding between the fan blade and the rotor during the production process, resulting in product scrapping. Contents of the invention [0003] Design purpose: To avoid the deficien...
