[0043] An electric actuator output torque measuring device, as Figure 1 shown, includes a pedestal 1, a rotating shaft 12, a runner 14, a slider 15, a vertical clamping plate 16, a horizontal support plate 17, a horizontal support plate 18, and a torque measuring device 3.

[0044] The pedestal 1 can be designed as a rectangle, and its upper surface has a chute 11. The chute 1 can be designed to be close to one end of the pedestal 1, as Figure 2 shown. A positioning hole is opened on the side wall at one end of the chute 11, and a through hole is opened on the side wall at the other end.

[0045] The rotating shaft 12 is arranged in the chute 11, and one end can be inserted into the positioning hole. A bearing is installed between this end of the rotating shaft 12 and the positioning hole. The other end of the rotating shaft 12 extends out of the pedestal 1 from the through hole, and a bearing is installed between this end of the rotating shaft 12 and the through hole, as Figure 3 shown.

[0046] The runner 14 is connected to the end of the rotating shaft 12 that extends out of the pedestal 1.

[0047] There are two sliders 15, which are arranged in the chute 11, fit with the side walls on both sides of the chute 11, and are threadedly connected to the rotating shaft 12. The helix directions of the connecting threads between the two sliders 15 and the rotating shaft 12 are opposite.

[0048] There are two vertical clamping plates 16, which are arranged oppositely and vertically connected to the two sliders 15. They are used to clamp and fix the electric steering gear 10 from both sides. They can be integrally formed with the two sliders 15, and the bottom abuts against the upper surface of the pedestal 1.

[0049] The horizontal support plate 17 is horizontally connected to the inner side of one vertical clamping plate 16, and the horizontal support plate 18 is connected to the inner side of the other vertical clamping plate 16, as Figure 4 shown.

[0050] The upper surface of the horizontal support plate 17 has a support groove 19. The support groove 19 forms an opening at the end of the horizontal support plate 17 away from the vertical clamping plate 16. Guide grooves 20 are provided on the side walls on both sides of the support groove 19, as Figure 5 shown.

[0051] One end of the horizontal support plate 18 away from the vertical clamping plate 16 is inserted into the support groove 19 from the opening. Guide blocks 13 are provided on both sides of this end of the horizontal support plate 18, and the two guide blocks 13 are inserted into the two guide grooves 20.

[0052] The whole formed by the horizontal support plate 17 and the horizontal support plate 18 has a certain distance from the upper surface of the pedestal 1. For example, it can be 10 cm, and it is used to carry the electric steering gear 10.

[0053] The torque measuring device 3 is arranged on the upper surface of the pedestal 1, opposite to the position of the sliding groove 11. It can be designed to be close to the other end of the pedestal 1, that is, close to the end of the pedestal 1 away from the sliding groove 11. Its input shaft is used to connect the output shaft of the electric steering gear 10 to measure the output torque of the electric steering gear 10.

[0054] For the electric steering gear output torque measuring device disclosed in the above embodiment, when measuring the output torque of the electric steering gear, the electric steering gear 10 can be placed on the whole formed by the horizontal support plate 17 and the horizontal support plate 18. Rotate the runner 14 to drive the rotating shaft 12 to rotate, so that the two sliders 15 and the vertical clamping plates 16 move towards each other to clamp and fix the electric steering gear 10 from both sides, which is convenient and fast. During this process, the horizontal support plate 17 and the horizontal support plate 18 will also slide correspondingly, and then use the torque measuring device 3 to measure the output torque of the electric steering gear 10. During the measurement process, the whole formed by the horizontal support plate 17 and the horizontal support plate 18 supports the bottom of the electric steering gear 10, which can prevent the electric steering gear 10 from being misaligned.

[0055] After the measurement of the output torque of the electric steering gear 10 is completed, the runner 14 can be rotated in the reverse direction to drive the rotating shaft 12 to rotate, so that the two sliders 15 and the vertical clamping plates 16 move away from each other to loosen the electric steering gear 10 and release the clamping and fixing of the electric steering gear 10. Then the electric steering gear 10 can be removed. The operation is convenient and has good versatility, and it can be used to measure the output torque of electric steering gears 10 of various sizes.

[0056] The electric rudder machine output torque measuring device disclosed in the above embodiments may be further designed to include legs 2, a base 4, a torque transmission shaft 5, a coupling 9, a dial 6, a pointer 8, and a cushion block 7.

[0057] There are four legs 2, which are supported below the four corner parts of the pedestal 1.

[0058] The base 4 is connected to the upper surface of the pedestal 1, and a torque measuring device 3 is connected thereto. Specifically, bolt connection can be adopted between the base 4 and the torque measuring device 3.

[0059] The torque transmission shaft 5 is connected to the input shaft of the torque measuring device 3 for connecting to the output shaft of the electric rudder machine 10.

[0060] The coupling 9 is connected to the torque transmission shaft 5 for connecting to the output shaft of the electric rudder machine 10.

[0061] The dial 6 has a central hole, and the central hole is sleeved on the outer periphery of the torque transmission shaft 5. A bearing is installed between the central hole and the torque transmission shaft 5.

[0062] The cushion block 7 is padded between the upper surface of the pedestal 1 and the bottom of the dial 6.

[0063] The pointer 8 is connected to the torque transmission shaft 5 and abuts against the dial 6. During the measurement of the output torque of the electric rudder machine, it can swing with the rotation of the output shaft of the electric rudder machine 10, indicating the scale on the dial 6, which is convenient for observing the rotation angle of the output shaft of the electric rudder machine 10.
