Auxiliary tool for assembling E-shaped self-aligning roller bearing

The utility model discloses an auxiliary tool for assembling an E-shaped self-aligning roller bearing and relates to the technical field of bearings. In order to solve the problems that according to an existing assembling technology for the E-shaped self-aligning roller bearing, a roller is usually put into a retainer firstly, then a rubber hammer is used for knocking lock points on the retainer, due to the fact that the machining consistency of the lock points is poor, the knocking force of the rubber hammer cannot be controlled, assembling is time-consuming and labor-consuming, and the assembling efficiency is low, the E-shaped self-aligning roller bearing assembling device aims at solving the problems that in the prior art, a roller is usually put into the retainer, and then the rubber hammer is used for knocking the lock points. A cavity with a circular section is formed in the upper surface of the lower mold, and an upper mold is arranged at the top of the cavity of the lower mold; a positioning boss is
