Abstract
The utility model discloses a bearing withdrawing tool for a motor, which comprises a bottom plate, wherein two vertical plates are arranged on the bottom plate in parallel, supporting plates extending towards the inner sides of the two vertical plates are arranged at the tops of the vertical plates, and a clamping groove is formed between the two supporting plates. According to the utility model, the bearing is arranged on the supporting plate, the rotor is positioned between the vertical plates, and the shaft of the piezoelectric motor is directly pressed down by the press, so that the bearing can be retracted, and the working efficiency is improved.
Description
Technical Field
The utility model relates to the field of motors, in particular to a bearing withdrawing tool for a motor.
Background
When the motor is assembled, after the bearing is assembled on the rotor, if defects are found in later detection of the assembled motor, the motor needs to be disassembled and reassembled again, the existing method is used for retracting the bearing from the rotor to and from the rotor, manual operation is needed, and the bearing is moved out from the rotor a little, so that the operation is more troublesome, and the working efficiency is low.
The disassembly is performed on site by pulling Ma Man slowly out as disclosed in CN213562321U, which is too inefficient.
Disclosure of Invention
The utility model aims to provide a bearing withdrawing tool for a motor.
The innovation point of the utility model is that the bearing is placed on the supporting plate, the rotor is positioned between the vertical plates, and the bearing can be retracted by directly pressing the shaft of the motor by the press, so that the working efficiency is improved.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
the utility model provides a motor is with moving back bearing frock, includes the bottom plate, its characterized in that, parallel arrangement has two risers on the bottom plate, and the riser top is equipped with the backup pad that stretches out towards two riser inboard, forms a draw-in groove between two backup pads.
The fixture is placed on a press workbench, the motor shaft is clamped in from one end of the clamping groove, the bearing is placed on the supporting plate, the rotating shaft is hung between the two vertical plates, the press is provided with a lower motor shaft, and the bearing is separated from the motor shaft, so that the working efficiency is improved.
Preferably, a perforation is arranged on the bottom plate, and the perforation is positioned between the two vertical plates. The higher the vertical plate is, the lower the overall rigidity is, and when the tail part of the motor shaft can extend into the through hole, the height of the vertical plate is reduced, and meanwhile, the weight of the bottom plate can be reduced.
Preferably, the bottom plate, the vertical plate and the supporting plate are connected through a bolt assembly, and a counter bore through which a bolt passes is arranged on the bottom surface of the bottom plate. When riser or backup pad damage, bolt assembly convenient to detach changes.
Preferably, the counter bore is a waist-shaped counter bore, and the long axis direction of the waist-shaped counter bore is perpendicular to the vertical plate. The distance between the two vertical plates can be adjusted, and the rotor with different sizes is suitable.
Preferably, the top surface of the supporting plate is provided with a supporting inclined surface at one side of the clamping groove. Because the distance between the rotor and the bearing of part motor is little, the backup pad is thick excessively, and the backup pad can't block into the interval between rotor and the bearing, but the backup pad is thin excessively for the thickness, and rigidity is not enough, can't bear the downforce of bearing, so adopts the support inclined plane, when guaranteeing the rigidity, can block into little interval.
Preferably, the vertical plate is formed by welding four square tubes. The weight of the tool can be effectively reduced.
The beneficial effects of the utility model are as follows:
1. according to the utility model, the bearing is arranged on the supporting plate, the rotor is positioned between the vertical plates, and the shaft of the piezoelectric motor is directly pressed down by the press, so that the bearing can be retracted, and the working efficiency is improved.
2. The utility model adopts the supporting inclined plane, ensures rigidity and can be clamped into a small space between the bearing and the rotor.
