It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0021] Embodiment: As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a pitch motor installation platform of the present utility model includes a workbench main body 1. A positioning frame 2 is provided on the upper surface of the workbench main body 1. A rotating seat 3 is provided on the positioning frame 2. A positioning cavity 4 for the vertical insertion of the shaft end of the motor to be inserted is provided on the rotating seat 3. A thick foam buffer layer 5 is provided inside the positioning cavity 4. The upper end of the rotating seat 3 protrudes above the positioning frame 2. A positioning mechanism 6 for rotating and positioning the rotating seat 3 is provided on the positioning frame 2. A pressing mechanism 7 for pressing and positioning the tail end of the motor is further provided on the workbench main body 1. By providing a positioning cavity 4 on the rotating seat 3 for the vertical insertion of the shaft end of the motor to be inserted, a preliminary positioning effect on the motor is achieved. In this way, the motor is erected, and then the tail end of the motor is pressed and positioned through the pressing mechanism 7, so as to prevent the motor from shaking during the assembly process with the fixing frame. Then, the installation position of the motor can be changed by rotating the rotating seat 3, and then the rotating seat 3 is fixed through the positioning mechanism 6 to prevent the motor from rotating during the assembly of the fixing frame, which is not convenient for installing the fixing frame.

[0022] Among them, the pressing mechanism 7 includes a support frame 8 on the rotating seat 3 and vertically downward. An electric telescopic cylinder 9 is provided vertically downward on the support frame 8. The telescopic end of the electric telescopic cylinder 9 is installed with a connecting block 11 through a spring seat 10. A pressing rotating plate 12 that rotates concentrically with the rotating seat 3 is installed on the connecting block 11 through a bearing. In this way, the pressing and fixing of the top end of the motor is realized through the telescopic movement of the electric telescopic cylinder, which has the characteristic of easy operation.

[0023] Among them, a rubber layer 16 is provided at the bottom of the pressing rotating plate 12, which plays a buffering role to avoid damaging the outer shell of the motor.

[0024] Among them, the positioning mechanism 6 includes a retaining seat 13 provided on the positioning frame. A resisting rod 14 is screwed horizontally into the retaining seat 13. In this way, the fixing effect is achieved by resisting with the low rod, which has the characteristic of easy operation.

[0025] Among them, the positioning cavity 4 is provided with a through hole 15 for the motor output shaft to pass through. A pressure sensor is provided between the spring seat 10 and the connecting block 11, so as to detect the downward pressure and avoid damaging the motor due to excessive pressure.

[0026] During operation, for this kind of pitch motor mounting platform, a positioning cavity 4 with a vertically inserted shaft end for the motor to be inserted is arranged on the rotating seat 3, which plays a preliminary positioning role for the motor. In this way, the motor is erected, and then the tail end of the motor is pressed and positioned through the pressing mechanism 7, so as to prevent the motor from shaking during the assembly process with the fixing frame. Then, the installation position of the motor can be changed by rotating the rotating seat 3, and then the rotating seat 3 is fixed by the positioning mechanism 6 to prevent the motor from rotating during the assembly of the fixing frame, which is not convenient for installing the fixing frame.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
