[0022] The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in some embodiments. The embodiments of the utility model will be described below with reference to the accompanying drawings.

[0023] The device for testing key parameters of a steering gear provided by the embodiment of the utility model, as shown in Figure 1 and Figure 2 , the base plate 1 bears the weight of the remaining components and the test stress, which is the foundation for stable operation of the device. A stand 8 is arranged at the center position of the base plate 1, and the stand 8 is vertically erected on the base plate 1. The steering gear 5 is nested on the stand 8, and the annular disc 6 is assembled on the steering gear 5. Four rudder wings 12 are arranged around the lower part of the steering gear 5. The outer diameter of the annular disc 6 is greater than that of the steering gear 5, and the inner circle of the annular disc 6 is accurately sleeved into the stand 8 of the steering gear 5 fixing tool. This enables the annular disc 6 to balance the downward pressure on the steering gear 5 component during assembly, achieving stable installation effect. The inner thread of the fastening bolt 7 is accurately matched with the upper thread of the stand 8 of the steering gear 5 fixing tool. After being tightened, the steering gear 5 is firmly fixed by the stable axial force, ensuring the relative position of each component constant during the test, preventing test errors caused by looseness, and being the core component for maintaining the overall stability of the device.

[0024] In some embodiments, as shown in Figure 2 , an M8 bolt 2 is used to firmly lock the fixed ring 3 on the predetermined position above the base plate 1. The fixed ring 3 tightly surrounds the bottom of the steering gear 5, strictly limits the horizontal displacement of the steering gear 5, and accurately anchors the horizontal initial position of the steering gear 5, preventing the horizontal displacement of the steering gear 5 during the test, laying a solid foundation for accurate testing. The sensor 4 is arranged relying on the fixed ring 3, and its position can be finely adjusted as needed, always maintaining the ideal detection distance and angle with the rudder wing 12 of the steering gear 5. During the test, the four sensors 4 can sensitively perceive and accurately capture the core signals such as the magnetic field changes caused by the action of the rudder wing 12, accurately measure the total delay time of each rudder wing 12 of the steering gear 5, and the action of each pair of rudder wings 12, and other key indicators, to provide key data support for in-depth evaluation of the performance of the steering gear 5, accurate troubleshooting of hidden troubles, and strong driving of the optimization and improvement of the steering gear 5 and reliable use.

[0025] In some embodiments, as shown in Figure 3As shown, the annular disc 6 is designed with a notch, which provides a safe exit path for the test connection line when the rudder 5 component is firmly pressed by the cylindrical rod, preventing the connection line from being damaged during dynamic testing, firmly protecting the stable and continuous transmission of test signals, and ensuring complete data collection. The protection of the annular disc 6 notch can be wrapped with flexible wear-resistant materials (such as rubber or silicone), which greatly reduces the friction probability of the connection line with the disc edge, reduces the risk of wear and tear, prolongs the service life of the connection line, reduces equipment maintenance costs and the possibility of testing interruption, and ensures stable and efficient testing.

[0026] In some embodiments, as shown in Figure 1 As shown, a hollow cylinder 11 is provided between the tightening bolt 7 and the annular disc 6, and the size of the hollow cylinder 11 is larger than the size of the rudder 5 fixing tool stand column 8. The inner circle of the hollow cylinder 11 smoothly sleeves the outer rod of the stand column 8 and presses on the annular disc 6, which can greatly reduce the tightening travel of the tightening bolt 7, improve assembly efficiency, and reduce the overall weight of the device, which is beneficial for operation and transportation.

[0027] In some embodiments, as shown in Figure 1 As shown, the upper edge of the fixed block 9 is provided with a positioning hole 10, and the rudder 5 is placed in the predetermined position in the tool through the positioning hole 10 on the fixed block 9 to ensure that the rudder 5 can be accurately placed in the predetermined position in the tool. The positioning hole 10 on the fixed block 9 will serve as an auxiliary positioning for the rudder 5, facilitating the operation and measurement in the subsequent assembly process.

[0028] In some embodiments, as shown in Figure 1 As shown, the material of the hollow cylinder 11 can be optimized, such as using a new type of composite material (such as carbon fiber reinforced plastic) to manufacture the hollow cylinder 11, which can greatly reduce the weight under the premise of ensuring the structural strength, enhance the compression and torsion resistance, effectively improve the dynamic response capability of the device, optimize the assembly convenience, and provide reliable support for long-term stable testing.

[0029] In some embodiments, as shown in Figure 1 As shown, the inner wall of the hollow cylinder 11 is designed with anti-slip texture or coating (such as micro-sand texture, Teflon coating), which significantly enhances the tightness of the cooperation with the annular disc 6 and the tightening bolt 7, prevents the components from loosening and displacing due to vibration and torsional force, ensures the stability of the mechanical structure of the device during testing, and improves the accuracy and reliability of the test data.

[0030] The utility model discloses a device through its innovative design, has a number of remarkable beneficial effects: one, the accurate installation of rudder motor is convenient, obtains accurate data, and the rudder motor can be accurately placed in the predetermined position in the device through the positioning hole on the fixed block, and the fixed block also has the effect of stabilizing the rudder motor, thereby effectively avoiding the rudder motor shaking, displacement when testing, and laying a solid foundation for obtaining high-precision test data;Two, sensor data acquisition optimization can simultaneously monitor and collect the data of four rudder wings, and the sensor can accurately position according to the actual rudder wing, capture the rudder wing action moment, and accurately collect the total delay time of each rudder wing action;Three, the annular disc gap design makes the machine component test connecting line reliable from the test device, guarantees that the test connecting line is not damaged in the dynamic test link, and in the dynamic test, the rudder motor frequently acts to produce vibration, torsional force, and if the connecting line is not properly planned, it is easy to be pulled, rubbed and damaged, so that the test is interrupted.
