Abstract
The invention discloses a welding fixture for outer rotor axial flow blade both sides welding. The welding fixture comprises a baseboard and a rotor positioning base fixedly arranged at the center of the baseboard and used for fixing a rotor. A plurality of groups of positioning assemblies for positioning blades to be welded are fixedly arranged on the baseboard, and each blade corresponds to one group of positioning blades. A plurality of yield holes for welding the front surfaces and the back surfaces of the blades are arranged on the baseboard, and therefore the front surfaces and the back surfaces of the blades can be welded in the welding process, the deformation amount of the welded blades is reduced, and workpieces can be taken out of the welding fixture easily after the welding is finished. The welding fixture is simple in structure, convenient to operate, low in processing cost and strong in practicality.
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 welding manner of outer rotor axial flow fan blade mainly adopts and is directly welded on rotor, and like this, the welding quality of blade directly affects the quality of blower fan, relative position between blade and rotor is fixing, if leaf position and different design, then can affect the performance of blower fan, as everyone knows, after welding due to weld seam from High-temperature cooling to room temperature state time Temperature Difference Ratio larger, if single-sided welding, welded part can produce distortion, directly affects the service life of blower fan.
Summary of the invention
the object of this invention is to provide a kind of welding tooling for outer rotor axial blade two-sided welding that a kind of structure is simple, welded workpiece deflection is little, processing cost is low.
for achieving the above object, the technical solution used in the present invention is: a kind of welding tooling for outer rotor axial blade two-sided welding, comprise base plate, be installed in the rotor fixed position seat for fixed rotor at described base plate center, described base plate is installed with the some groups of positioning components for locating blade to be welded, blade described in every sheet, corresponding to positioning component described in a group, described base plate also offers multiple emptiness avoiding hole for carrying out positive and negative welding to described blade.
preferably, described positioning component has multiple, often organizes described positioning component and includes multiple support bar for supporting described blade.
preferably, described base plate is also provided with the hold-down mechanism for compressing described blade, described hold-down mechanism comprises the compressor arm be located at rotationally 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 evenly offered along same circumferencial direction, and described emptiness avoiding hole is fan-shaped.
further preferably, described blade has 5, and correspondingly, described emptiness avoiding hole has 5, and described positioning component has 5 groups, and described hold-down mechanism also has 5 groups.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages: the welding tooling for outer rotor axial blade two-sided welding of the present invention, by offering emptiness avoiding hole on base, make to weld the tow sides of blade in welding process, deformable blade amount after welding is little, can be taken out in welding tooling by workpiece easily after welding terminates meanwhile, structure is simple, easy to operate, processing cost is low, practical.
Accompanying drawing explanation
accompanying drawing 1 is the structural representation of the welding tooling for outer rotor axial blade two-sided welding of the present invention;
accompanying drawing 2 is the decomposition texture schematic diagram of the welding tooling for outer rotor axial blade two-sided welding of the present invention;
wherein: 1, base plate; 11, emptiness avoiding hole; 2, rotor fixed position seat; 3, rotor; 4, blade; 5, hold-down mechanism; 51, compressor arm; 6, support bar.
Detailed description of the invention
below in conjunction with accompanying drawing, technical scheme of the present invention is further elaborated.
shown in Fig. 1, Fig. 2, a kind of welding tooling for outer rotor axial blade two-sided welding, comprise base plate 1, be installed in the rotor fixed position seat 2 for fixed rotor 3 at base plate 1 center, base plate 1 is installed with the some groups of positioning components for locating blade 4 to be welded, every sheet blade 4 corresponds to one group of positioning component, base plate 1 also offers multiple emptiness avoiding hole 11 for carrying out positive and negative welding to blade 4, described emptiness avoiding hole 11 quantitatively with blade 4 phase one_to_one corresponding, and be uniformly distributed along same circumferencial direction, described emptiness avoiding hole 11 is in fan-shaped.
shown in Fig. 1, Fig. 2, this base plate 1 is provided with multiple positioning component corresponding with blade 4, often organizes positioning component and includes multiple support bar 6 for support blade 4, by this positioning component, can limit blade 4 exactly and be welded on position on rotor 3.
shown in Fig. 1, Fig. 2, in order to ensure in welding process, blade 4 can not offset, in the present embodiment, base plate 1 is also provided with the hold-down mechanism 5 for compressing blade 4, this hold-down mechanism 5 comprises the compressor arm 51 be located at rotationally on base plate 1, one end of compressor arm 51 is pressed on blade 4 rotationally, after the position of blade 4 being limited by positioning component, be pressed on blade 4 by compressor arm 51, can effectively prevent blade 4 from offseting in welding process.In the present embodiment, blade 4 to be welded has 5, and accordingly, emptiness avoiding hole 11 has 5, and positioning component has 5 groups, and hold-down mechanism 5 also has 5 groups.
in welding process, rotor fixed position seat 2 to be arranged on base plate 1 and rotor 3 is fixed on rotor fixed position seat 2, then determine the position of blade 4 to be welded and rotor 3, by positioning component, blade 4 position is positioned, and be pressed on blade 4 in case offset in welding process Leaf 4 position by compressor arm 51.During welding, first the front of blade 4 being welded, then by welding through the reverse side of the emptiness avoiding hole 11 pairs of blades 4 on base plate 1, after having welded, welding tooling can be taken off to obtain the workpiece after welding.
in sum, welding tooling for outer rotor axial blade two-sided welding of the present invention, by arranging emptiness avoiding hole on base plate, make in welding process, can weld the tow sides of blade, the deformable blade amount that welding is obtained is little, and can be taken out from welding tooling easily by the workpiece after the welding of this welding tooling, and its structure is simple, processing cost is low, practical.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
