[0028] Example
[0029] In order to solve the problems existing in the shaft press used for rotor assembly in the prior art, Figure 1 and Figure 2 As shown, the present application discloses a rotor shaft pressing machine, comprising: a machine platform 10, with an air avoidance groove 11 opened in the middle of the machine platform 10;
[0030] The support plate 20 is fixed to the machine platform 10 via four polished rods 30;
[0031] A pressure plate is provided below the support plate 20 and allows the four polished rods 30 to pass through;
[0032] The lifting drive member 50 is disposed on the support plate 20. Specifically, the lifting drive member 50 of the present application adopts a cylinder with a stroke of 600 mm, and the driving shaft of the lifting drive member 50 is connected to the shaft pressure plate 40 through a weighing sensor 60;
[0033] The displacement sensor 70 is fixed on the support plate 20 and connected to the pressure plate.
[0034] During the specific implementation process, the operator places the rotor body above the air avoidance groove 11 and pre-inserts the shaft core to be assembled from above, and then controls the lifting drive 50 to drive the pressure plate to descend until the shaft core is pressed into the rotor body. During this process, the weighing sensor 60 will detect the pressure applied to the shaft core by the pressure plate 40 in real time, and the displacement sensor 70 will also detect the displacement value of the pressure plate 40. After the shaft core and the rotor body are pressed together, if the values detected by the weighing sensor 60 and the displacement sensor 70 are both preset values, then it proves that the shaft core is pressed into the rotor body qualified, otherwise, it is unqualified.
[0035] In this embodiment, a double start button 120 is provided on the front side of the machine 10, which can realize fool-proof control and avoid operator's misoperation.
[0036] In this embodiment, four shaft sleeves 41 are arranged inside the pressure plate of the present application, and four light rods 30 are arranged through the four shaft sleeves 41 in sequence. In this way, when the lifting drive 50 drives the pressure plate 40 to rise and fall, the four light rods 30 cooperate with the four shaft sleeves 41 to guide the pressure plate, thereby improving the lifting stability of the pressure plate 40.
[0037] In order to install the displacement sensor 70 , the present application provides a mounting groove 21 on the support plate 20 , and the displacement sensor 70 is fixed in the mounting groove 21 and connected to the pressure plate.
[0038] In this embodiment, the present application installs a ∩-shaped protective cover 80 on the outside of the machine 10, and a safety grating 90 is provided on the front side of the ∩-shaped protective cover 80. During actual operation, if the safety grating 90 detects that an object has been inserted, the entire machine will stop running, thereby avoiding harm to the operator's body and greatly improving the safety factor.
[0039] In addition to the above structure, the present application also provides a control box 100 for overall control on the right side of the ∩-shaped protective cover 80. A touch screen 110 is provided on the control box 100, and the operator can also use the touch screen 110 to detect the weighing sensor 60 and the displacement sensor 70 to obtain relevant numerical values in real time, thereby detecting problems existing in the operation of the axle press.
