Abstract

The invention includes the following steps: mounting and fixing the future jointing or fastening member and then starting to be heated; moving the amorphous alloy pin selected on the basis of the specific size of the future jointing or fastening member into the between of the future jointing or fastening members in the working region after the temperature in the working region is in a stable state and then going on heating; driving the future jointing or fastening member to contact with the amorphous alloy pin to make it deform and then be inserted in the clamping slot on the future jointing or fastening member and at last finishing jointing or fastening the members.

Description

technical field [0001] The present invention relates to the connection technology of fine solids, in particular to a mechanical connection or fastening method of small parts, which is especially suitable for the connection and fastening of fine parts of Micro Electro Mechanical System (MEMS, Micro electro mechanical system). Background technique [0002] For the connection of two solids, the traditional methods include bolt connection, rivet connection, pin, key and spline connection, bonding and welding, etc. Connecting devices must have a strong ability to withstand the working environment and physical contact (such as pressure, heat transfer), etc., so as to ensure the reliability of the system. Under the premise of ensuring reliability, low cost, simple implementation method, and convenient maintenance or replacement are expected ideal goals. [0003] The working principle of different types of traditional connection methods makes various defects inevitably appear: bolt...
