[0032] It should be noted that the present soldering positioning assembly can be mainly applied to brazing of ceramic kovar, and can be extended to brazing and sealing of other metal and non-metal materials, thereby improving the success rate of brazing and sealing.
[0033] As one of the embodiments, as shown in Figure 6 The welding assembly 50 includes an upper kovar ring 51, a ceramic workpiece 52, and a lower kovar ring 56. The outer periphery of one end of the ceramic workpiece 52 is attached to the inner wall of the upper kovar ring 51, and the outer periphery of the other end is attached to the inner wall of the lower kovar ring 56, thereby assembling the welding assembly 50.

[0036] As one of the embodiments, the ceramic workpiece 52 adopts 99 porcelain.
[0037] Further, as shown in Figures 2 to 3 The positioning sleeve 40 includes a first sleeve 41 and a second sleeve 42. The positioning assembly cavity 31 is provided with a positioning plate 32, which is located between the first fixed sleeve plate 10 and the second fixed sleeve plate 20.

The positioning plate 32 is provided in the positioning assembly cavity 31, and the outer periphery of the positioning plate 32 is attached to the inner periphery wall of the middle part of the welding assembly 50, thereby realizing positioning of the middle part of the welding assembly 50 and improving the assembly positioning accuracy of the entire welding assembly 50.
[0038] The first sleeve 41 and the second sleeve 42 ensure the axial gap between the upper kovar ring 51, the lower kovar ring 56, and the ceramic. The first sleeve 41 and the second sleeve 42 are processed from 95 porcelain or 99 porcelain, thereby ensuring synchronous displacement change between the workpieces during high-temperature brazing, and avoiding differences.
[0039] As one of the embodiments, the first fixed sleeve plate 10, the second fixed sleeve plate 20, the first sleeve 41 and the second sleeve 42 are made of 95 porcelain material.
[0040] As one of the embodiments, the positioning shaft 30 and the positioning plate 32 are made of low expansion alloy. The positioning shaft 30 and the positioning plate 32 are made of the same material as the upper Kovar ring 51 and the lower Kovar ring 56, which prevents the size from expanding too much during high-temperature brazing, causing the tooling to be locked or the workpiece to be lifted and detached.
[0041] As one of the embodiments, as shown in Figure 6 The ceramic workpiece 52 has a first opening 53 and a second opening 54 at both ends, and a middle cavity 55 is provided in the ceramic workpiece 52, the middle cavity 55 is in communication with the first opening 53 and the second opening 54 at both ends, the positioning shaft 30 passes through the first opening 53, the middle cavity 55 and the second opening 54 in sequence, and the positioning plate 32 is located in the middle cavity 55, the outer circumferential surface of the positioning plate 32 is attached to the inner circumferential wall of the middle cavity 55, so as to realize the positioning of the ceramic workpiece 52 and ensure the coaxial assembly precision of the ceramic workpiece 52 with the first fixed sleeve plate 10 and the second fixed sleeve plate 20.
[0042] Further, as shown in Figures 1 to 3 The upper end of the first fixed sleeve plate 10 is provided with a first fastening ring 13 for binding the welding assembly 50, and the first fastening ring 13 is arranged along the edge of the first limiting groove 12. The first fastening ring 13 is fastened to the edge of the outer circumferential surface of the lower Kovar ring 56, and the edge shape of the lower Kovar ring 56 is fixed. During the welding process, the lower Kovar ring 56 is prone to local deformation or warping due to thermal stress. The first fastening ring 13 tightly binds the outer circumferential surface of the lower Kovar ring 56 to limit its deformation and ensure that the lower Kovar ring 56 maintains a stable geometric shape during the welding process.
[0043] As one of the embodiments, the first fastening ring 13 is made of molybdenum wire, which is wound around the lower Kovar ring 56 to form the first fastening ring 13. The molybdenum wire has certain strength and toughness, and can withstand the stress during the welding process without being easily broken or deformed, ensuring the reliability of the first fastening ring 13. The molybdenum wire can be easily processed into the required shape, facilitating manufacturing and installation.
[0044] Further, as shown in Figures 1 to 3As shown, the first fastening ring 13 is provided with a first stainless steel ring 14, which is arranged along the edge of the first limiting groove 12. The thermal expansion coefficient of stainless steel is relatively large, which will significantly expand at high temperature, so that the first stainless steel ring 14 is tightly attached to the outer wall of the lower Kovar ring 56. During high-temperature welding or brazing, the expansion of the first stainless steel ring 14 can automatically compensate for the gap caused by thermal expansion and provide additional fastening force, ensuring that the lower Kovar ring 56 is always in a stable state, further reducing the risk of outward bending of the lower Kovar ring 56.
[0045] Further, as shown in Figures 1 to 3 The first stainless steel ring 14 is provided with a plurality of first stainless steel rings 14, which are arranged along the circumference of the first fastening ring 13. The plurality of first stainless steel rings 14 are arranged on the first fastening ring 13, which uniformly distributes the fastening force to the outer circumferential surface of the lower Kovar ring 56, avoids local stress concentration, and reduces the risk of deformation of the lower Kovar ring 56 due to uneven stress. Uniformly distributed fastening force helps to maintain the geometric shape of the lower Kovar ring 56, improving the quality and consistency of welding or brazing.
[0046] Further, as shown in Figures 1 to 3 The lower end of the second fixing sleeve plate 20 is provided with a second fastening ring 23 for binding the welding assembly 50, and the second fastening ring 23 is arranged along the edge of the second limiting groove 22. The second fastening ring 23 is fastened to the edge of the outer circumferential surface of the upper Kovar ring 51 to fix the edge shape of the upper Kovar ring 51. During welding, the upper Kovar ring 51 is prone to local deformation or warping due to thermal stress. The second fastening ring 23 tightly binds the outer circumferential surface of the upper Kovar ring 51 to limit its deformation, ensuring that the upper Kovar ring 51 maintains a stable geometric shape during welding.
[0047] Further, as shown in Figures 1 to 3 The second fastening ring 23 is provided with a second stainless steel ring 24, which is arranged along the edge of the second limiting groove 22. The thermal expansion coefficient of stainless steel is relatively large, which will significantly expand at high temperature, so that the second stainless steel ring 24 is tightly attached to the outer wall of the upper Kovar ring 51. During high-temperature welding or brazing, the expansion of the second stainless steel ring 24 can automatically compensate for the gap caused by thermal expansion and provide additional fastening force, ensuring that the upper Kovar ring 51 is always in a stable state, further reducing the risk of outward bending of the upper Kovar ring 51.
[0048] Further, as shown in Figures 1 to 3As shown, the second stainless steel ring 24 is provided with a plurality of second stainless steel rings 24, and the plurality of second stainless steel rings 24 are arranged at intervals along the circumference of the second fastening ring 23. The plurality of second stainless steel rings 24 are arranged at intervals on the second fastening ring 23, and the fastening force is uniformly distributed to the outer circumferential surface of the upper Kovar ring 51, so as to avoid local stress concentration and reduce the risk of deformation of the upper Kovar ring 51 caused by uneven stress. The uniformly distributed fastening force helps to maintain the geometric shape of the upper Kovar ring 51 and improve the quality and consistency of welding or brazing.
[0049] Further, as shown in the drawings, Figures 1 to 3 As shown, the inner circumferential surface of the first positioning hole 11, the inner circumferential surface of the second positioning hole 21, and the inner circumferential surface of the third positioning hole 33 are respectively attached to the outer circumferential surface of the positioning shaft 30, so as to ensure the coaxial assembly of the first fixed sleeve plate 10, the second fixed sleeve plate 20 and the positioning plate 32, and improve the assembly positioning accuracy of the welding assembly 50.

[0054] As shown in the drawings, Figure 4 The lower end of the ceramic workpiece 52 is assembled into the inner circumferential surface of the lower Kovar ring 56, and the inner circumferential wall of the ceramic workpiece 52 is attached to the outer circumferential surface of the positioning plate 32, and after assembly, the ceramic workpiece 52 is closely attached to the lower Kovar ring 56, and each workpiece can only rotate slightly and cannot shake;

[0056] As shown in the drawings, Figure 3 The upper Kovar ring 51 is assembled into the second positioning groove of the second fixed sleeve plate 20, and after assembly, the fitting size is re-measured to ensure that the upper Kovar ring 51 is closely fitted with the second fixed sleeve plate 20.
[0057] After assembly, the overall height and dimensional fit must be measured to ensure that the workpiece is assembled in the designed position and that the tooling can only rotate without any shaking.
[0058] like Figure 2 As shown, a first fastening ring 13 with a first stainless steel ring 14 is tied to the outside of the lower Kovar ring 56 near the brazing seam.
