While these loading test devices typically include torque sensors, these sensors are not integrated into the rudder system tester, requiring manual interpretation and leading to resource waste. Furthermore, during actual loading tests, adjustments to the loading torque and inertia are necessary. Inaccurate manual adjustments to these parameters can affect the test results, impacting both efficiency and quality. Utility Model Content

Detailed Implementation

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1 to 12The passive servo system automatic loading device shown includes a loading platform 1, on which the servo motor is mounted via an automatic clamping device 2. It also includes an automatic torsion bar switching mechanism 3, a stiffness adjustment mechanism 4, a torsion bar clamping mechanism 5, an inertia adjustment mechanism 6, and a loading channel assembly 7. The torsion bar clamping mechanism 5 is used to fix and limit the torsion bar 8, assisting the automatic torsion bar switching mechanism 3 and the stiffness adjustment mechanism 4 in their switching and stiffness adjustment actions. The inertia adjustment mechanism 6 is used for inertia loading adjustment. The loading channel assembly 7 connects the servo motor to the stiffness adjustment mechanism 4 and the inertia adjustment mechanism 6, and automatically uploads the stiffness and inertia detection results to the control system.

[0029] It should be noted that the automatic clamping device 2 used to clamp the servo motor in this embodiment adopts a clamping cylinder, which is a general clamping component.

[0030] In this embodiment, the automatic lever changing mechanism 2 includes a lever changing disk 9, and the torsion bars 8 are evenly distributed vertically along the circumference on the lever changing disk 9. The lever changing disk 9 can be driven to rotate around its axis by a driving component.

[0031] The instruction manual needs to be supplemented as follows: the rod changing plate 9 is driven to rotate by a motor. The rotating plate 9 is equipped with a guide sleeve 23 for positioning the torsion bar. The torsion bar 8 moves up and down in the guide sleeve 23 under the combined action of the inertia adjustment mechanism 6 and the torsion bar clamping mechanism 5. The top of the motor is fixedly connected to the loading worktable 1 through the connecting bracket 24.

[0032] In this embodiment, the stiffness adjustment mechanism 4 includes a positioning base plate 10 arranged parallel to the torsion bar 8, a slide table 11 arranged parallel to the positioning base plate 10, and the torsion bar clamping mechanism 5 fixed on the slide table 11, which can slide vertically up and down perpendicular to the positioning base plate 10.

[0033] It should be noted that the slide table 11 on the positioning base plate 10 is also driven by a motor and a ball screw.

[0034] In this embodiment, the torsion bar clamping mechanism 5 includes an L-shaped positioning frame 12, on which a set of clamping plates 13 are arranged in parallel. The two clamping plates 13 clamp and limit the torsion bar 8 under the action of external force.

[0035] It is necessary to supplement the instruction manual that the two clamping plates 13 arranged opposite each other are driven by a motor and a cam. During the rotation of the cam driven by the motor, one clamping plate 13 is intermittently driven to move towards the other clamping plate 13, forming a clamping of the torsion bar 8. The two sides of the two clamping plates 13 are slidably connected by an elastic return rod 25. When the torsion bar clamping mechanism 5 needs to release the torsion bar 8, the motor drives the cam to rotate until its teeth move away from the clamping plate 13. The clamping plate 13 is reset under the pressure of the spring return rod 25, releasing the torsion bar 8. This realizes the clamping and releasing of the torsion bar 8, which facilitates the replacement of the torsion bar 8 and can be used in conjunction with the stiffness adjustment mechanism 4 to adjust the stiffness of the torsion bar 8.

[0036] When it is necessary to replace the torsion bar 8, firstly, the existing torsion bar 8 is clamped by the torsion bar clamping mechanism 5. After clamping, the stiffness adjustment mechanism 4 drives the torsion bar clamping mechanism 5 to move downward, so that the torsion bar 8 is released from the loading spindle 14 and falls into the position of the rod changing plate 9. The pin hole on the torsion bar 8 engages with the pin on the rod changing plate 9. The rod changing plate 9 rotates: the torsion bar clamping mechanism 5 releases the torsion bar 8, and then the stiffness adjustment mechanism 4 drives the torsion bar clamping mechanism 5 downward until it is moved to the far end as a whole, so as to avoid interference when the rod changing plate 9 rotates. Then the rod changing motor is started. The rotating rod changing plate 9 rotates, rotating the required torsion bar 8 to the center line position of the loading spindle 14; new torsion bar 8 installation: stiffness adjustment mechanism 4 drives torsion bar clamping mechanism 5 to move upward to a suitable position, clamping torsion bar 14 through clamping plate 13, stiffness adjustment mechanism 4 drives torsion bar clamping mechanism 5 upward again, pushing torsion bar 8 into spline shaft 15, and after being sent to the predetermined position through magnetic connection at the front end of torsion bar 8, stiffness adjustment mechanism 4 moves to a suitable position according to stiffness requirements, and the automatic rod changing action of torsion bar 8 is completed.

[0037] In this embodiment, the loading channel assembly 7 includes a loading spindle 14. The top of the loading spindle 14 is connected to the servo motor, and the end is engaged with the torsion bar 8 via a spline shaft 15. A torque sensor 16 is provided between the spline shaft 15 and the loading spindle 14. Inertia disks 17 are symmetrically arranged on both sides of the loading spindle 14. The inertia disks 17 adjust the inertial force applied to the loading spindle 14 by the inertia adjustment mechanism 6. An inertia block sensing plate 18 is installed on the loading spindle 14.

[0038] In this embodiment, the inertia adjustment mechanism 6 includes a ball screw 19, which passes vertically through the loading spindle 14. The inertia disk 17 is mounted on the sliding seat of the ball screw 19, and the ball screw 19 is driven to rotate by a motor.

[0039] In this embodiment, the motor used to drive the ball screw 19 to rotate is mounted on the linear module 20. The motor can be driven to move vertically up and down through the linear module 20. The output end of the motor is connected to the ball screw 19 through a clutch block 21 and a movable clutch block 22.

[0040] It is necessary to supplement the instruction manual that, in order to achieve the opposite movement of the two sets of inertia disks 17, the ball screw 19 of the inertia adjustment mechanism 6 is provided with positive and negative threads. The ball screw 19 preferably adopts a trapezoidal screw design and has a self-locking function.

[0041] The inertia sensor 18 and torque sensor 16 connected to the loading spindle 14 can monitor the inertia torque of the inertia adjustment mechanism 6 loaded onto the inertia disk 17 and the torque transmitted from the torsion bar 8 in real time and upload the feedback to the control system for real-time recording and display.

[0042] In this embodiment, one or more sets of the passive rudder system automatic loading devices can be installed simultaneously on the loading workbench 1.

[0043] In this embodiment, the loading platform 1 is arranged in a cross shape, which can simultaneously perform loading tests on four sets of servo motors.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
