The invention relates to the technical field of bearing pulling devices, in particular to a bearing pulling device. The bearing pulling device comprises a bearing pulling seat, a bearing magnetic positioning part, a fixing piece and a fastening piece, wherein the bearing magnetic positioning part is placed in a groove of the bearing pulling seat and fixed through the fixing piece, and the fastening piece is screwed into an upper threaded hole formed in the bearing pulling seat; a bearing workpiece needing to be pulled out is directly placed in the device, one end of the bearing workpiece makes contact with the round face of a bearing through a round magnetic positioning block, and the bearing is subjected to face positioning and adsorbed to be fixed; and the contact is surface contact, so that the coaxiality of a screw and a bearing axis is ensured. The placement is simple without additional action, and the efficiency is high.
Description
technical field [0001] The invention relates to the technical field of pull-out bearing devices, in particular to a pull-out bearing device. Background technique [0002] In the field of general machinery, small bearings or small rotary bodies are separated from the shaft. The bearing needs screw jacking, and the operation steps are cumbersome; the screw jacking bearing is a point contact, which cannot guarantee the coaxiality of the bearing and the ejection screw, and the ejection screw is easy to be skewed; it cannot be automatically centered, and the work efficiency is low. [0003] The present invention directly puts the workpiece that needs to be pulled out of the bearing into the device, and one end uses a circular magnetic positioning block to contact the circular surface of the bearing, and the surface is positioned and adsorbed to fix the bearing; the contact is surface contact to ensure that the screw is coaxial with the shaft center of the bearing It is easy to p...
