Detailed Description
The present invention will now be described in further detail with reference to the attached drawings, which are provided for purposes of illustration and not limitation.
Referring to fig. 1, 2 and 3, the brazing tool for ensuring the uniform distribution degree of the blades comprises a base 1, wherein a through groove 2 is formed in the center of the base 1, a positioning ring 3 for positioning the blades is arranged above the through groove 2, a plurality of inserts 4 for positioning the blades 5 are arranged on the positioning ring 3, and the inserts 4 are uniformly distributed on the circumference of the positioning ring 3;
the profiles of the two sides of the insert 4 are matched with the profile of the blade 5;
the base 1 on the two sides of the through groove 2 is provided with a stepped boss, and the boss is provided with a support ring 6 for supporting the positioning ring 3.
Specifically, in the aerospace equipment, an engine fan stator assembly is formed by brazing a cantilever blade at the position 42 in the axial direction and a shell, and the blade and the shell are made of titanium alloy TC11 materials. The titanium alloy TC11 material is characterized by light specific gravity, 4.5 specific gravity, high strength, corrosion resistance and low temperature resistance, and is between iron and aluminum. The utility model discloses a solve the problem that the equipartition degree of blade can't be guaranteed, designed the frock of inserting that can improve the back blade equipartition degree of brazing, evenly set up 42 on holding ring 3 along the circumferencial direction and inserted 4, every both sides profile of inserting 4 is identical completely with the leaf basin leaf back of the body profile size of blade 5, specifically refer to fig. 2 and fig. 3. Meanwhile, considering that the insert 4 generates an axial force by its own weight to deform the blade 5, the base 1 is provided with the support ring 6 for supporting the positioning ring 3, that is, the support ring 6 is added to the air inlet edge of the part, so that the insert 4 can be supported while the blade 5 is prevented from deforming at a high temperature. The insert 4 is made of a material with a large linear expansion coefficient, the volume and the mass are the same, the volume expansion is the same at the same temperature, and the blades 5 are distributed to meet the uniform distribution requirement by simultaneously carrying out the thermal forming technology at the brazing temperature.
