Technical Field

The utility model relates to the technical field of motors, in particular to an auxiliary tool for installing an end cover of a permanent magnet motor.

Background

Permanent magnet motors are direct current motors in which the stator is a permanent magnet and only the rotor is a coil. The advantages are that: the structure is simple, and the reliability is high; the average efficiency is high; the temperature rise is low; the motor is small in size and light in weight; the power factor is high; the starting torque is large; the force energy index is good; the air gap can be increased, so that a novel magnetic circuit is formed conveniently; the armature reaction is small, and the overload resistance is strong; high efficiency, energy saving and is generally used in low power occasions.

In the process of installing the end cover, as the rotor of the permanent magnet motor is provided with strong magnetism, when the rotor is installed in the motor, the rotor can be adsorbed on one side inner wall of the motor stator, so that the rear end cover spigot and the machine base spigot are eccentric, the longer rear end cover bolt needs to be replaced, the end cover spigot is slowly controlled to enter the machine base through fastening and positioning of the bolt, and then the required bolt is replaced, so that the installation of the rear end cover is completed. In the above steps, when a longer bolt is used for fastening, one bolt cannot be fastened in place at a time, and the opposite angles or the sequential slow fastening is necessary, so that the traditional manual wrench is troublesome.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1, 2 and 3, fig. 1 is a front view of the whole structure of the present utility model; FIG. 2 is a partial cross-sectional view of the structure of the present utility model; fig. 3 is a front view of the construction of the tooling body according to the present utility model.

An auxiliary tool for installing an end cover of a permanent magnet motor comprises a machine base 1, a rear end cover 2 and a tool main body 3.

The rear end cover 2 is positioned at the top of the machine base 1, two sides of the top of the machine base 1 are respectively provided with a machine base spigot 101, two sides of the rear end cover 2 are provided with end cover spigot 201 corresponding to the machine base spigot 101, and the end cover spigot 201 and the machine base spigot 101 are matched for use.

When the rear end cover 2 is mounted, the mounting of the rear end cover can be completed by aligning the machine base spigot 101 with the end cover spigot 201, then allowing the end cover spigot 201 to enter the machine base 1, and then mounting appropriate bolts in the end cover spigot 201 and the machine base spigot 101.
