The invention relates to a part installation tool which comprises a base, multiple sectioning chucks and a mandrel. A threaded hole is formed in the base; the multiple sectioning chucks are arranged on the first surface of the base, can move along the radial direction of the base and are of sector structures; a first notch is arranged on the inner corner part of each sectioning chuck; the first notches of the multiple sectioning chucks enclose to form a holding cavity; the holding cavity is located above the threaded hole; the mandrel is in threaded connection with the base; and a circular truncated cone-shaped extrusion head is arranged at the first end of the mandrel and is located in the holding cavity. According to the technical scheme, a damping tape can be pre-opened, so that a sufficient space is provided for the installation of a welded bellow, a correct assembling relationship is realized on a shell, the damping tape and the welded bellow, the assembling quality is improved, and the part installation tool has the advantages of light weight, small size, easiness in processing, simplicity in assembling and the like.
