[0002] A superconducting magnet refers to an electromagnet that uses a second-type superconductor with a high transition temperature and a particularly high critical magnetic field to make a coil under low temperature conditions. Its main feature is that there is no electrical loss caused by wire resistance, and no iron The magnetic loss caused by the existence of the core has strong practical value. In the manufacturing process of large superconducting magnets, it is impossible to use the vacuum pressure impregnation (VPI) manufacturing process in an autoclave. Usually, a stainless steel mold is used to weld the inner mold to provide vacuum and pressure. The environment and carbon steel hard mold provide a stable shape for vacuum pressure impregnation, feed the superconducting coil through the position of the superconducting joint, and realize the internal heating of the coil to complete the vacuum pressure impregnation and insulation curing of the resin. This process is in the intelligent manufacturing process. The sealing performance is high, and the existing sealing device is fixed by bolts, but the bolt tightening tool can only fix the bolts on one side at a time, which not only has low sealing efficiency, but also causes uneven stress on the gasket , the gasket is easy to dislocate, and the sealing accuracy is poor, which will have an important impact on vacuum pressure impregnation, and even cause the coil to be scrapped

[0003] Aiming at the deficiencies of the prior art, the present invention provides a superconducting magnet VPI mold joint insulation sealing device and its technology, which can simultaneously and synchronously tighten multiple groups of bolts, uniform force, high sealing precision, and can adjust the sleeve The position of the cylinder is suitable for superconductors of different sizes, etc., which solves the problem that the existing sealing device is fixed by bolts, but when fixing, only one side of the bolt can be fixed at a time, not only the sealing efficiency is low, but also the sealing gasket will be damaged. Uneven force, easy misalignment of gaskets, and poor sealing accuracy will have an important impact on vacuum pressure impregnation, and even lead to the scrapping of coils
