Sleeve dismounting tool for deep groove ball bearing

The invention relates to the technical field of bearing dismounting, in particular to a deep groove ball bearing sleeve dismounting tool which comprises a rack and a deep groove ball bearing body. The rack is further provided with a dismounting assembly used for placing the deep groove ball bearing and dismounting the rivet. The dismounting assembly comprises a base, a bearing support, a fixing support, a sleeve, a loading rod, a baffle, a first elastic piece and a first linear driver. A bearing support is placed through a base, then the bearing support is fixed through an ejector rod on the bearing support and abuts against a rivet, and then a sleeve and a loading rod on the sleeve are installed through a placing groove in a fixing support. A first linear driver with the output end located over the loading rod pushes the loading rod, the elastic force of a first elastic piece is overcome through an abutting plate on the loading rod, and therefore a punching head can move downwards to punch out a rivet conven
