Description

Technical Field

[0001] The utility model relates to the technical field of motor rotor maintenance, in particular to a special tool for installing a motor rotor dynamic balancing block. Background Art

[0002] When performing a dynamic balancing test on a motor rotor with a cast aluminum structure, it is necessary to install a balancing block on the balancing column, and then use an installation tool to knock on the balancing column to squeeze the balancing block to fix it. There is a dust baffle at the non-load end of the motor rotor. The dust baffle blocks the working space at the front end of the balancing column, which affects the knocking angle. As a result, the knocking angle is not correct when the balancing column is knocked, making it impossible for the aluminum balancing column to be subjected to horizontal force, causing the aluminum balancing column to break from the root and making it impossible to complete the dynamic balancing test. Utility Model Content

[0003] In view of the above technical problems, the utility model provides a special tool for installing a motor rotor dynamic balancing block, which is used to solve the problem that an aluminum balancing column cannot be horizontally stressed during the installation of the motor rotor dynamic balancing block.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A special tool for installing a dynamic balancing block of an electric motor rotor comprises a motor shaft, a rotor is mounted on the motor shaft, a balancing column is provided at the end of the rotor, a balancing block is sleeved on the balancing column, and a dust shield is also provided on the motor shaft, the dust shield is located on one side of the balancing column, an installation tool is provided above the dust shield, one end of the installation tool is in contact with the balancing column, and the other end is a knocking end, a slide groove is provided at the bottom of the installation tool, and the dust shield is located in the slide groove.

[0006] A handle is provided on the upper portion of the installation tool.

[0007] The end surface of the knocking end is provided with an anti-slip pattern.

[0008] One end of the installation tool that contacts the balance column is provided with a pit, and the head of the balance column is located in the pit.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure and low manufacturing cost; an operator strikes the installation tool, and the force is transmitted to the balance column through the striking end, so that the balance column is horizontally squeezed and the force is evenly applied; the utility model is easy to use and has obvious effect, thereby fixing the balance block. BRIEF DESCRIPTION OF THE DRAWINGS
