Embodiment

[0028] A jig for electron beam welding of multi-stage blisks provided in this embodiment is designed according to the three-stage blisks of a certain type of engine. The central position of No. 2 blisk, No. 2 blisk and No. 3 blisk, see figure 1 , so the structure of the designed fixture is as follows figure 2 As shown, it is specifically composed of base 1, fixed column 3, lower fixed spacer 6, upper fixed spacer 9, cover plate 12, compression nut 13 and hoisting earring 14, fixed column 3, lower fixed spacer 6, The upper fixed spacer 9, the cover plate 12, and the compression nut 13 are sequentially assembled on the base 1 with the No. 1, No. 2 and No. 3 integral blisks to be welded from bottom to top, and the hoisting earrings 14 are fixedly connected to the fixed column 3 upper end, see Figure 5 .

[0029]The base 1 is a circular disc with a coaxial limiting boss on its upper surface. The diameter of the boss matches the inner diameter of the hole on the lower end of t...

Abstract

The invention discloses a fixture used for multistage overall blade disk electron beam welding. The fixture is composed of a base, a fixed stand column, a lower fixed partition block, an upper fixed partition block, a cover plate, a pressing nut and a hoisting lug ring; the fixed stand column, the lower fixed partition block, the upper fixed partition block, the cover plate and the pressing nut, and a to-be-welded first overall blade disk, a to-be-welded second overall blade disk and a to-be-welded third overall blade disk are sequentially assembled on the base from bottom to top in a staggered manner; and the hoisting lug ring is fixedly connected to the upper end face of the fixed stand column. The fixture is simple in structure, convenient to operate and use and high in reliability, welding of the multistage overall blade disks can be achieved at a time, the production efficiency of welding is improved, the problems that welding of a large-diameter wheel disk in the multistage overall blade disks cannot be easily controlled, and ununiform deformation can be very easily caused can also be solved, the rejection rate is reduced, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of manufacturing tools for aero-engine rotating parts, and in particular relates to a fixture for electron beam welding of multi-stage integral blisks. Background technique [0002] As a rotating part in an aero-engine, the three-stage blisk has very strict requirements on its dynamic balance and static balance. Any uneven deformation caused by the welding process will seriously affect the overall balance of the part. Since the three-stage blisk is composed of a single No. 1 blisk, No. 2 blisk and No. 3 blisk, it is necessary to separate the No. 1 blisk from the middle of the No. 2 blisk, No. 2 blisk and No. 3 blisk before use The middle part of the blisk is connected by electron beam welding to complete the connection of the three overall blisks. [0003] When electron beam welding is used, on the one hand, the uneven width of the molten pool formed by welding on the front and back of the welding part will...
