In which like parts are designated by like reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings. The terms "inner" and "outer" are used to refer to directions toward and away from, respectively, the geometric center of a particular component.
The utility model provides a special core cast aluminium machine that leaves of motor cast aluminium rotor, as shown in fig. 1~ 3, the special core cast aluminium machine that leaves of motor cast aluminium rotor includes: the device comprises a frame 1, a main transmission shaft 2, a rotary table 3 and a driving mechanism 4;
a shaft hole penetrating through the axis of the rack 1 is formed in the rack 1, the main transmission shaft 2 is rotatably installed in the shaft hole of the rack 1, the upper end of the main transmission shaft 2 upwards penetrates through the shaft hole, and the lower end of the main transmission shaft 2 downwards penetrates through the shaft hole; a mounting hole is formed in the axis position of the rotary table 3, and the upper end of the main transmission shaft 2 is connected with the mounting hole; the driving mechanism 4 is used for driving the main transmission shaft 2 to rotate, and the rotation of the main transmission shaft 2 can drive the rotary table 3 to rotate.
It can be understood that when the aluminum casting operation is performed on the motor rotors with different specifications, only the motor rotors need to be installed on the rotary table 3, and then the device is started, so that the driving mechanism 4 drives the main transmission shaft 2 to rotate, and the rotation of the main transmission shaft 2 drives the rotary table 3 to rotate, so that the motor rotors rotate; the main transmission shaft 2 can generate radial acting force when rotating, so that the coaxiality of the main rotating shaft cannot be controlled, and the condition of uneven cast aluminum is caused; the tapered roller bearing 5 can bear radial acting force generated by the main transmission shaft 2 during rotation, and improves the centering precision of the main transmission shaft 2 and the coaxiality during rotation, so that the aluminum casting process of the rotor can be stably and uniformly carried out, and the quality of the rotor after aluminum casting is improved.
In order to further enable the aluminum casting process of the rotor to be stably and uniformly carried out, a circle of balance steps 310 are arranged on the periphery of the mounting hole on the lower surface of the rotary table 3, a plane bearing 6 is arranged between the upper end surfaces of the machine frame 1, and the lower surface of the balance steps 310 is pressed on the plane bearing 6. The structure can reduce the weight borne by the main transmission shaft 2, improve the stability of the main transmission shaft 2 and the rotary table 3 during rotation, and is favorable for improving the stability and uniformity of the rotor in the aluminum casting process.
When the turntable 3 is operated at a high speed, grease in the flat bearing 6 is thrown out, and the thrown grease contaminates the turntable 3, so that an oil baffle plate 7 is provided on the outer periphery of the flat bearing 6. The oil baffle 7 can prevent the grease added in the plane bearing 6 from being thrown out when the rotary table 3 of the rotary table 1 is operated at a high speed.
In order to prevent the unbalance of the main transmission shaft 2 in the rotating process, the main transmission shaft is close to the center bearing 8 arranged on the hole wall of the shaft hole at the upper end of the shaft hole, and the center bearing 8 is sleeved on the main transmission shaft 2. Even if the main transmission shaft 2 is slightly unbalanced in the operation process, the main transmission shaft can be adjusted and compensated through the self-aligning bearing 8 so as to achieve the purpose of balance.
Because the weights of the rotors with different specifications are different, if the rotating speeds of the rotors with different specifications in the aluminum casting process are the same, the aluminum casting rate is insufficient, and the whole quality of the cast aluminum rotor is greatly influenced. Therefore, the lower end of the main transmission shaft 2 penetrates through the shaft hole and is provided with a large V-belt pulley 9; the driving mechanism 4 comprises a driving motor 410, a small V-belt pulley 420 is mounted on an output shaft of the driving motor 410, and a V-belt 10 is connected between the small V-belt pulley 420 and a large V-belt pulley 9. The driving motor 410 adopts a variable-frequency speed-regulating three-phase asynchronous motor, the variable-frequency speed-regulating three-phase asynchronous motor is matched with a belt transmission main transmission shaft 2 of a triangular leather, so that the rotating speed matched with the weight of workpieces of different specifications can be obtained, and meanwhile, the protection is carried out during overload, and the equipment maintenance is facilitated.
In order to facilitate the overall movement of the frame 1, the frame 1 is provided with a hanging ring 11.
