The electric motor end cap pressing machine of the present embodiment it is specifically used as follows:
First, as shown in figure 3, motor housing 8 is located on motor housing positioning mechanism, vertically oriented set is plugged in electricity
In the installation through-hole of machine shell, the installation through-hole of motor housing is in a vertical state;At this point, the upper end of vertically oriented column is located at electricity
The top of the upper surface of machine shell.
Electric motor end cap 7 is located in the upper end of vertically oriented column(Have on the lower end surface of electric motor end cap for installing rotor
The bearing mounting hole of bearing), the upper end of vertically oriented column is plugged in the bearing mounting hole on the lower end surface of electric motor end cap(Vertically
The outer diameter of positioning column is identical as the internal diameter of bearing mounting hole on the lower end surface of electric motor end cap).Electric motor end cap is supported in vertical fixed
On the column of position, and electric motor end cap is determined by the bearing mounting hole cooperation on the lower end surface of vertically oriented column and electric motor end cap
Position.Electric motor end cap is positioned by vertically oriented column, and motor housing is positioned by vertically oriented set, to guarantee motor
The concentricity of the installation through-hole of end cap and motor housing.
Second, the hoistable platform of press drives end cap pressing sleeve to push together with vertical compression bar, in this process:Vertical pressure
Bar is contacted with vertical frizzen first, drives upper piston to move down with lower piston by vertical frizzen, and upper piston is displaced downwardly to the
The lower section of three interfaces;
After upper piston is located at the lower section of third interface, end cap pressing sleeve is contacted with electric motor end cap, and electric motor end cap is pressed into
On motor housing, the bulge loop 7.1 of electric motor end cap is pressed into the installation through-hole of motor housing, in this process vertically oriented column with
Piston body moves down together with electric motor end cap(The intracorporal gas of vertical cylinder below piston body by third interface, second interface with
Connecting tube discharge).
The hoistable platform of third, press drives end cap pressing sleeve to move up reset together, in this process, the second reseting pressuring spring
Upper piston and lower piston is driven to move up reset, the first reseting pressuring spring drives piston body and vertically oriented column to move up reset.
Since electric motor end cap is positioned by vertically oriented column, and motor housing is positioned by vertically oriented set, such as
This, it is ensured that the concentricity of the installation through-hole of electric motor end cap and motor housing, to effectively solve current electric motor end cap press fitting
Machine is difficult to ensure the concentricity of the installation through-hole of electric motor end cap and motor housing, and electric motor end cap is caused to be pressed the problem of damaging.
