The invention provides a design method of a special fixture for
energy storage spot welding positioning based on a guide vane
assembly, which comprises the following steps of: determining an
energy storage spot welding process
route, firstly spot-
welding a partition plate I and a partition plate II, secondly spot-
welding a
honeycomb, and then spot-
welding and combining with a main body part. Determining a part positioning reference, and selecting the excircle of the part as a positioning
reference surface; a point
electrode holder material is selected, and
brass or red
copper is selected as the point
electrode holder material. A detachable point
electrode base is designed, the first partition plate and the second partition plate are preferentially assembled in the
spot welding process, the partition plate
assembly is formed, welding points are increased, the welding strength is improved, and the
honeycomb assembly is formed. The method has the advantages that the stability and inclusiveness are considered while the
dimensional precision of the part is guaranteed, and the spot welding efficiency is improved. Through the adaptive
radian, the integrating degree between the
honeycomb and the partition plate is improved, the
stress strength of parts during
energy storage spot welding is improved, the
bonding strength between the parts is enhanced, deformation of the partition plate and the honeycomb is reduced, and the vacuum
brazing quality of the parts is improved.
