Description
Technical field
The present invention relates to the manufacture field of a kind of fan blade and outer rotor welding method, particularly relate to a kind of welding tooling for outer rotor axial blade two-sided welding.
Background technology
At present, the mainly employing of the welding manner of outer rotor axial flow fan blade is directly welded on rotor, and so, the welding quality of blade directly affects the quality of blower fan, relative position between blade with rotor is fixing, if leaf position and different design, then can affect the performance of blower fan, it is commonly known that, after welding due to weld seam from High-temperature cooling to room temperature state time Temperature Difference Ratio bigger, if single-sided welding, welded part can be deformed, and directly affects the service life of blower fan.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, a kind of welding tooling for outer rotor axial blade two-sided welding that welded workpiece deflection is little, processing cost is low.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of welding tooling for outer rotor axial blade two-sided welding, including base plate, the rotor fixed position seat for fixed rotor that is installed in described base plate center, some groups it are installed with for the positioning component that blade to be welded is positioned on described base plate, every described blade, corresponding to positioning component described in a group, described base plate is further opened with multiple emptiness avoiding hole for described blade carries out positive and negative welding.
Preferably, described positioning component has multiple, often organizes described positioning component and all includes multiple support bar for supporting described blade.
Preferably, described base plate being additionally provided with the hold-down mechanism for compressing described blade, described hold-down mechanism includes the compressor arm being rotatably arranged on described base plate, and one end of described compressor arm is pressed on described blade rotationally.
Preferably, all described emptiness avoiding hole on described base plate is uniformly offered along same circumferencial direction, and described emptiness avoiding hole is sector.
It is further preferred that described blade has
5
Sheet, correspondingly, described emptiness avoiding hole has
5
Individual, described positioning component has
5
Group, described hold-down mechanism also has
5
Group.
Utilization due to technique scheme, the present invention compared with prior art has the advantage that the welding tooling for outer rotor axial blade two-sided welding of the present invention, by offering emptiness avoiding hole on base, make can the tow sides of blade be welded in welding process, deformable blade amount after welding is little, and meanwhile, workpiece can be taken out after terminating in welding tooling by welding easily, simple in construction, easy to operate, processing cost is low, practical.
