Embodiment Construction

[0016] From figure 1 , figure 2 , image 3 It can be seen that Al in a welded artificial retina 2 o 3 A fixture for ceramic and titanium rings, which includes a graphite base 2, a graphite compact 1, and the like. Described graphite base 2 is provided with a boss 21, is provided with on the boss 21 and is used for placing Al 2 o 3 The groove 22 of the ceramic disc 3 can be Al 2 o 3 A ceramic disc 3 is embedded therein. The graphite briquetting block 1 is provided with a fastening groove 11 matched with the boss 21 on the graphite base 2, and the top surface of the fastening groove 21 is provided with a draw-in groove 13 for pressing the titanium ring 5, The titanium ring can be clamped in the slot, which can not only play a position-limiting role, but also prevent the specimen from being connected to the fixture due to the spreading of the filling material.

[0017] A number of observation fine-tuning windows 14 are provided on the surrounding walls of the fastening ...

Abstract

The invention relates to Al in welding artificial retina 2 o 3 A fixture for ceramic and titanium rings, which includes a graphite base and a graphite compact, the graphite base is provided with a boss, and a boss is provided on the boss for placing Al 2 o 3 The groove of the ceramic disc; the graphite briquetting block is provided with a fastening groove matched with the boss on the graphite base, and the top surface of the fastening groove is provided with a draw-in groove for pressing the titanium ring, Several fine-tuning windows for observation are arranged on the surrounding walls of the fastening groove on the graphite briquetting block. By observing the fine-tuning window, the position of the filling material at the connection interface can be fine-tuned, and the limit situation of the entire test piece can be observed. The invention has reasonable composition and structure, easy operation and use, reliable connection and fixation, and can avoid dislocation and unwelded defects, and is especially suitable for connecting Al in artificial retina. 2 o 3 Clamping of ceramic and titanium ring structures.

Description

technical field [0001] The invention relates to a fixture for welding, in particular to a welding fixture for Al in artificial retina. 2 o 3 Clamps for ceramic and titanium rings. Background technique [0002] Artificial retina technology helps patients obtain basic vision by replacing the functionless retina with electronic devices. Its successful application has great economic value and social significance. Al 2 o 3 The ceramic disc and titanium ring connection structure is an important part of the artificial retina structure, and the ceramic / metal composite structure requires Al in the welding process 2 o 3 The ceramic disc and the titanium ring must be completely aligned and sealed, and there must be no defects such as misalignment or lack of welding, otherwise the airtightness of the entire structure will be affected, which in turn will affect the use of the artificial retina. [0003] Therefore, in welding Al 2 o 3 For ceramic discs and titanium rings, it is ne...
