Bearing automatic assembly device

Abstract

The present invention is an automatic assembly device for bearings, which includes a fixed seat and a controller, a rotor positioning mechanism, a bearing push-in mechanism installed on the fixed seat, the rotor positioning mechanism, the bearing push-in mechanism and the controller are electrically connected, and the assembly device also It includes at least one bearing feeding mechanism electrically connected to the controller, and the bearing feeding mechanism pushes the bearing into at least one corresponding rotor positioning mechanism; the rotor positioning mechanism vertically fixes the rotor axis and makes the axis, The bearings are arranged vertically in the axial direction; the bearing pushing mechanism is arranged above the rotor positioning mechanism, and the concentrically fixed bearing and the rotor axis move vertically toward each other until the bearing is installed on the axis. The invention has the advantages that the vertical structure is adopted, which saves space compared with the traditional horizontal type, ensures the assembly quality of the shaft center and the bearing, and can improve the automation level of the device.

Description

technical field [0001] The invention relates to a bearing installation device on a motor rotor, in particular to a bearing assembly device with automatic bearing feeding and accurate positioning. Background technique [0002] During the assembly process of the motor rotor, the assembly of bearings at both ends of the shaft is one of the necessary assembly processes. In order to replace manual work and accurately and efficiently assemble the bearing on the shaft, this fully automatic bearing assembly device needs to solve four problems at the same time. First, the device needs to precisely position the shaft and the bearing concentrically. The second is that the bearing is pressed into the shaft center assembly stage, and the pushing force of the pushing mechanism needs to be constant to ensure the installation quality of the bearing. The third is that the automatic device can automatically feed the assembled bearings at both ends of the shaft. Fourth, the automation degree...

[0003] Chinese utility model CN201856075U discloses a bearing press-in machine. Although the mechanism has good assembly accuracy, it is a semi-automatic equipment. Both the rotor and the bearing need to be manually unloaded. At the same time, its structure is horizontal, which cannot Combination with other automatic processes of the rotor

Chinese utility model CN202877830U discloses a synchronous press-in machine for the front and rear rotor bearings and the middle cover. The mechanism adopts a vertical structure as a whole, and the pressure head device has a buffer spring, which ensures the assembly quality, but the disadvantage is that the bearings cannot be automatically fed. , the buffer mechanism is more complex and affects the stability of the structure
