It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0031] The steering engine often needs to work in complex working conditions in practical application, such as inclination, inversion or lateral installation, which may affect the torque output. Through multi-angle testing, various working conditions of the steering engine in practical application can be simulated, the performance in different installation attitudes can be evaluated, and the reliability in actual use can be ensured. The load distribution of the mechanical structure (such as gear, bearing, etc.) of the steering engine is different at different angles, and some angles may be the weak point of the mechanical structure. Through multi-angle testing, the load capacity of the steering engine mechanical structure at different angles can be detected, and potential weaknesses can be found to provide basis for improving design.

[0032] In order to solve the technical problem that the installation angle and load direction of the steering engine torque testing device are difficult to adjust flexibly during testing, resulting in low testing efficiency and difficulty in meeting testing requirements, the utility model provides a steering engine torque testing device, which can accurately test the torque output of the steering engine by simulating the installation condition of the steering engine in practical application, and the testing table can rotate around the base and be fixed at different angles, so that the torque of the steering engine at different angles can be tested conveniently, and the flexibility and accuracy of testing are improved.

[0033] Please refer to Figure 1 and Figure 2 , the steering engine torque testing device comprises a base 1, a testing table 2, a torque testing assembly 3 and a fixing assembly; one end of the testing table 2 is rotatably connected with the base 1, and is used for installing a steering engine 6; the torque testing assembly 3 is installed on the testing table 2, and is used for connecting the steering engine 6 installed on the testing table 2 to test the torque output by the steering engine 6; the fixing assembly is connected with the testing table 2 and the base 1, and is used for fixing the position of the testing table 2 after rotation.

[0034] In the device, the test table 2 can be installed with the torque test assembly 3 and the rudder 6, and the connection of the rudder 6 and the torque test assembly 3 can be conveniently realized, so that the torque test can be facilitated. During the test process, the output end of the rudder 6 is connected with the torque test assembly 3, and when the rudder 6 works, the torque test assembly 3 can accurately measure the torque value output by the rudder 6. In addition, the test table 2 can rotate around the base 1, and the torque test in multiple angles and directions can be realized. The setting of the fixing assembly can effectively fix the position of the test table 2 after rotation, so as to ensure the accuracy and stability of the test. The whole device has simple structure and convenient operation, and the efficiency and accuracy of the torque test of the rudder 6 are greatly improved.

[0035] Please refer to Figure 2 In some possible embodiments, the base 1 is composed of a bottom plate 11 and two side plates 12, and the two side plates 12 are oppositely arranged on both sides of the test table 2.

Through the movement of the indicating block 21 in the first arc-shaped groove 13, the rotation angle of the test table 2 can be observed intuitively, and the accuracy and convenience of the test are further improved. At the same time, the setting of the first arc-shaped groove 13 can also limit the rotation range of the test table 2, so as to avoid the damage or inaccurate test caused by excessive rotation of the test table 2.

Through the arrangement of the second arc-shaped slot 14, the first fixing assembly 4 can fix the test table 2 at different positions, so that the test table 2 can be stopped at any angle, further increasing the flexibility of the rotation of the test table 2 and the diversity of the test. When the test table 2 is rotated to the required angle, the operator can rotate the locking nut 42 to tightly fit on the side of the side plate 12, so as to stably fix the test table 2 at the current position. This fixing method is simple and reliable, which can effectively ensure the accuracy and stability of the test.

The fixing bolt 53 is located on the side of the sleeve 51 and cooperates with the threaded hole opened on the side of the sleeve 51. When it is necessary to adjust the position of the test table 2, the operator can loosen the fixing bolt 53 so that the support rod 52 can be freely rotated in the sleeve 51, thereby adjusting the angle of the test table 2. After the adjustment is completed, the fixing bolt 53 is tightened again, and the test table 2 can be stably fixed at the current position, further ensuring the accuracy and stability of the test.
