[0017] like Figure 1 and Figure 2The servo-stabilized platform frame assembly disturbance torque detection device shown is used for torque detection of the servo-stabilized platform frame 7. The servo-stabilized platform 7 is a prior art and is the object to be detected by the device. Its assembly quality will be evaluated by the detection device and method of the present invention. The servo-stabilized platform 7 frame is composed of a pitch and yaw double frame structure. Usually, the optical system or sensor is installed on the yaw frame. The two ends of the yaw frame are connected to the pitch frame through bearings, and the two ends of the pitch frame are connected to the body through bearings. The yaw frame and the pitch frame are perpendicular to each other in the motion axis, so as to realize the movement of the optical system or sensor in the spatial range position or angle. The present invention includes a base plate 1, a rotating mechanism and a force sensing mechanism. The rotating mechanism is installed at the center position of the upper surface of the base plate 1, the force sensing mechanism is installed at the front end of the rotating mechanism, and the bottom of the force sensing mechanism is slidably connected to the upper surface of the base plate 1. The servo-stabilized platform frame 7 is connected to the rotating mechanism; the rotating mechanism drives the servo-stabilized platform 7 to rotate, and the force sensing mechanism adjusts the contact distance according to the position of the optical system at the front end of the servo-stabilized platform frame 7 to realize the measurement of the disturbance torque.

[0018] Furthermore, a slide rail is provided on the upper surface of the front end of the bottom plate 1, and the force sensing mechanism is slidably connected to the slide rail. The bottom plate 1 is used as the bottom mounting plate of the device, and is mainly used to install the driving mechanism 2 and the mounting bracket 4; the end surface of the bottom plate 1 is provided with a slide rail mounting position, which is connected to the mounting bracket 4 through a slider. This connection method not only ensures the stability of the mounting bracket, but also facilitates its position adjustment.

[0019] Further, such as Figure 1As shown, the rotating mechanism can make the servo stable platform frame 7 rotate at a constant speed around its rotation axis, and the rotation speed can be adjusted. The rotation speed can be adjusted to different values ​​as needed to meet different detection requirements, so as to better observe and measure the changes of the interference torque at different rotation speeds. The rotating mechanism includes a driving mechanism 2, a rotating plate 3 and a mounting base 5; the driving mechanism 2 is connected to the center of the upper surface of the base plate 1, and the rotating plate 3 is a rectangular plate structure composed of a slide rail section and a straight plate section. The rotating plate 3 is arranged parallel to the base plate 1, and the straight plate section of the rotating plate 3 is connected to the upper surface of the driving mechanism 2. The mounting base 5 is vertically connected to the slide rail section of the rotating plate 3 and can slide back and forth on the slide rail; the servo stable platform frame 7 is horizontally installed on the mounting base 5; the main function of the rotating plate 3 is to drive the servo stable platform frame 7 to rotate, and it is rigidly connected to the driving mechanism 2 with screws to ensure the effective transmission of power; on it A slide rail installation position is provided at the end, which is connected to the installation base 5 through a slider. This connection method enables the installation base 5 to move within a certain range to adjust the position of the servo stable platform frame 7; the installation base 5 is mainly used to install the servo stable platform frame 7, and the installation base 5 can be designed according to different product structures and sizes of the servo stable platform frame 7 to ensure that the servo stable platform frame 7 can be firmly installed to provide a stable foundation for subsequent inspections; it is installed on the rotating plate 3 through a slider, and the slider can move back and forth through the slide rail. This feature helps to adjust the rotation center of the servo stable platform frame 7 to be consistent with the rotation center of the drive mechanism 2.

[0020] The driving mechanism 2 is a box-type structure, in which a driving motor and a reducer are connected. The driving motor drives the reducer to move, and the reducer drives the mounting base 5 to drive the servo stabilization platform 7 to rotate by rotating the flat plate 3. The driving mechanism 2 is composed of a driving motor and a reducer with a certain reduction ratio, and is the rotational power source of the interference torque detection device. The driving motor drives the reducer to move, and the reducer drives the servo stabilization platform frame 7 to rotate by rotating the flat plate 3, providing stable rotational power for the entire detection device.

[0021] The rotating plate 3 drives the servo stable platform frame 7 to rotate at a constant speed, and the rotation angle is +90° for both left and right rotation angles relative to the measurement axis direction.

[0022] The force sensor device achieves the transmission measurement of the interference torque by adjusting the contact position between the force sensor 6 and the optical system set at the front end of the servo stable platform frame 7. When the outer frame of the servo stable platform frame 7 rotates, the interference torque between the inner and outer frames will cause the optical system to have a movement trend. After the force sensor 6 contacts the optical system of the servo stable platform frame 7, the interference force generated by the movement between the inner and outer frames is transmitted to the optical system, thereby causing the corresponding pressure value of the force sensor 6 to change. At this time, the pressure value on the force sensor 6 is the interference torque value. The force sensor device includes a mounting bracket 4 and a force sensor 6. The mounting bracket 4 is slidably connected to the slide rail of the base plate 1, and the force sensor 6 is horizontally mounted on the mounting bracket 4.

[0023] The upper end of the mounting bracket 4 is provided with two U-shaped grooves, and the force sensor 6 slides up and down in the grooves to ensure that the force sensor 6 is consistent with the center of the optical system at the front end of the servo stabilization platform frame 7. The mounting bracket 4 is mainly used to install the force sensor 6. The two U-shaped grooves on its upper end are convenient for adjusting the height of the force sensor 6 to ensure that the force sensor 6 is consistent with the center of the optical system of the servo stabilization platform frame 7, thereby improving the accuracy of the measurement. The force sensor 6 contacts the optical system of the inner frame of the servo stabilization platform frame 7 during the detection process. When there is an interference torque between the inner and outer frames, the movement trend of the optical system will cause the force sensor to be subjected to pressure. The force sensor 6 converts the pressure into an electrical signal or other measurable signal. The pressure value corresponding to the signal is the interference torque value.

[0024] Furthermore, a slide rail is provided on the upper surface of the front end of the base plate 1, and the force sensing mechanism is slidably connected to the slide rail; the rotating mechanism includes a driving mechanism 2, a rotating plate 3 and a mounting base 5; the rotating mechanism includes a driving mechanism 2, a rotating plate 3 and a mounting base 5; the driving mechanism 2 is connected to the center of the upper surface of the base plate 1, and the rotating plate 3 is a rectangular plate structure composed of a slide rail section and a straight plate section. The rotating plate 3 is arranged parallel to the base plate 1, and the straight plate section of the rotating plate 3 is connected to the upper surface of the driving mechanism 2. The mounting base 5 is vertically connected to the slide rail section of the rotating plate 3 and can slide back and forth on the slide rail; the servo stabilization platform frame 7 is horizontally installed on the mounting base 5; The driving mechanism 2 is a box-type structure, in which a driving motor and a reducer are connected. The driving motor drives the reducer to move, and the reducer drives the mounting base 5 to drive the servo stabilization platform frame 7 to rotate by rotating the flat plate 3.

On the basis of the above embodiments, this embodiment provides a detailed operation process of a servo stabilization platform frame assembly interference torque quantitative detection method. First, adjust the servo stabilization platform 7 frame to the pitch or yaw direction, move the mounting base 5 horizontally, adjust the servo stabilization platform 7 frame rotation center to be consistent with the rotation center of the drive mechanism 2, and then set the drive mechanism rotation speed to 0.5° / s by adjusting the drive motor parameters. The rotation range is ±90° for both left and right rotation angles relative to the measurement axis direction. Adjust the mounting bracket position and adjust the force sensor to contact the front end of the optical system.

[0027] Finally, the drive motor is started, the output value of the force sensor 6 is recorded during the rotation process, and a curve between the rotation angle and the disturbance torque value is drawn to achieve quantitative detection of the disturbance torque of the servo stable platform frame 7 and judge the assembly quality of the servo stable platform 7 frame. If the curve shows that the disturbance torque value is within a reasonable range, it means that the assembly quality is good; if it exceeds the reasonable range, it indicates that there may be problems in the assembly process and needs to be improved.
