Automatic bearing press-fitting machine

Abstract

The invention relates to a bearing press-fitting device, in particular to an automatic bearing press-fitting machine for motor rotors. The invention aims at providing the automatic bearing press-fitting machine which is capable of pressing and fitting rotors at the two ends at one time, is simple to operate, safe and reliable, high in press-fitting efficiency and good in press-fitting quality. The automatic bearing press-fitting machine comprises a base, press-fitting cylinders, a left bearing supply mechanism, a right bearing supply mechanism, a left bearing locating mechanism, a right bearing locating mechanism and a rotor locating mechanism; the left and the right bearing supply mechanisms supply bearings to the left and the right bearing locating mechanisms; the bearings are located by the left and the right bearing locating mechanisms; the left bearing locating mechanism and the rotor locating mechanism are pushed by a piston rod of the press-fitting cylinders to slide to the position of the right bearing locating mechanism to press and fit the bearings at the two ends at one time. In addition, the cylinders in the whole device are all provided with magnetic switches. A PLC (programmable logic controller) can automatically control the operation of the whole device by the signals from the magnetic switches to the PLC so as to press and fit the bearings at the two ends automatically.

Description

technical field [0001] The invention relates to a bearing pressing device, in particular to an automatic bearing pressing machine for motor rotors. Background technique [0002] Existing motor rotor bearing press-fitting device has two kinds of vertical type and horizontal type. For the vertical bearing press-fitting device, the operator needs to manually put one bearing into the lower press-fit mold, put the rotor into the press-fitting machine, put the other bearing into the upper end of the rotor shaft, and hold the rotor by hand to carry out the bearing at both ends. Press-fitting, this kind of press-fitting device, the efficiency of the press-fitting process is low, the operation risk factor is relatively high, and the labor intensity of the operator is relatively high. Although the horizontal bearing press-fitting machine reduces the risk factor of the operator to a certain extent, when press-fitting, one end of the rotor shaft is pressed first, and then the other end...

Problems solved by technology

For the vertical bearing press-fitting device, the operator needs to manually put one bearing into the lower press-fitting mould, put the rotor into the press-fitting machine, put the other bearing into the upper end of the rotor shaft, and hold the rotor by hand for both ends of the bearing. Press-fitting, this kind of press-fitting device, the efficiency of the press-fitting process is low, the operation risk factor is large, and the labor intensity of the operator is relatively high

Although the horizontal bearing press-fitting machine reduces the risk factor of the operator to a certain extent, when press-fitting, one end of the rotor shaft is pressed first, and then the other end of the shaft is pressed. This press-fitting method makes the rotor bearing The press-fitting efficiency is low, and the press-fitting quality of the bearings at both ends of the shaft will also be affected
