Problems solved by technology

However, in the process of press-fitting, the longitudinal position positioning of each device is not accurate, which will cause the radiator to deviate in the longitudinal direction, which will cause the bump on the upper end of the radiator to collide with the upper pull ring, and then will be damaged during the press-fitting process. The surface of the raised part of the upper pull ring and the radiator is scratched, and even the electrical test fails

Description

technical field [0001] The invention relates to a flexible positioning device and a positioning method for a thyristor silicon stack. Background technique [0002] At present, the thyristor silicon stack is one of the important components of the converter valve. The thyristor silicon stack includes a left press block, a right press block, a spring assembly, a radiator, an upper pull ring and a pull ring; among them, due to structural design needs , the upper end of the heat sink has a raised portion, the raised portion protrudes into the inner side of the upper pull ring and the gap between the raised portion and the upper pull ring is very small. In the production process of the thyristor silicon stack, it is necessary to arrange the left pressing block, the spring assembly, the radiator and the right pressing block in sequence along the horizontal direction, and then press the left pressing block, the spring assembly, the radiator and the right pressing block through high ...
