Detailed Description

A novel optical device TO eccentric sealing tool is shown in figures 5 TO 8 and comprises: frock electrode holder 11, holding ring 12, wherein:

the tool electrode seat 11 is made of electrode copper with good plasticity, good stability and small electrode loss. Low production cost and high stability. The tool electrode seat 11 is provided with an inner hole with the diameter equal TO the outer diameter of the tube seat, the upper part of the inner hole is used for placing a metal tube seat of a device TO be sealed and welded with the TO, the lower part of the inner hole is used for placing a positioning ring 12, and the whole tool is directly assembled on a sealing and welding machine table.

The positioning ring 12 is made of plastic king (steel for race) with high lubrication, corrosion resistance, high temperature resistance and low temperature resistance (capable of working for a long time at the temperature of +250 ℃ TO-180 ℃), and the size of the inner surface of the positioning ring 12 is consistent with that of a required sealing welding pipe body and used for positioning TO eccentricity. The positioning ring 12 is embedded in the tool electrode base 11, the positioning ring and the tool electrode base are in tight fit, the TO can be directly placed into a tool, and the TO eccentricity is positioned.

The height of the tool electrode seat 11 is H1, the height of the positioning ring 12 is H2, and the values of H1-H2 are larger than the height of the device metal tube seat and smaller than the height of the TO tube cap. The inner diameter of the positioning ring 12 is slightly larger than the TO outer diameter by 0.02mm, the outer diameter of the positioning ring is tightly matched with the tool electrode seat 11, and the outer diameter of the positioning ring is slightly larger than the outer diameter of the device metal tube seat by 0.01 mm.

In the embodiment, the outer diameter D1 of the tool electrode holder 11 is 14mm, the height H1 is 8mm, and the tool electrode holder is small and exquisite in structure and convenient to replace in time; the inner diameter D3 of the positioning ring 12 is 3.8mm, the outer diameter D2 is 5mm, the height H2 is 5.7mm, and the depth H3 of the TO cap inserted into the positioning ring 12 is 1.2 mm.

As shown in fig. 7 and 8, the positioning ring 12 can be used for concentric position limitation when a product is put into the tool, and can play a role in guiding when the product is put, so that the outer diameter D4 of the metal pipe seat and the outer diameter D5 of the TO pipe cap are concentric.

The use method of the tool comprises the following steps:
