[0025] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0026] The utility model discloses a device for detecting the polarity of deflection of a steering gear rudder blade. Figure 1As shown, it includes a first clamp 50 for clamping the front end of the servo 100 and a second clamp 60 for clamping the rear end of the servo 100; it also includes a first measuring piece 70 located above the first clamp 50 and the second clamp 60, and a second measuring piece 80 located below the first clamp 50 and the second clamp 60; the first measuring piece 70 and the second measuring piece 80 are both provided with measuring windows facing the rudder blade 110 of the servo 100; the first measuring piece 70 and the second measuring piece 80 are both installed with measuring sensors, and the measuring sensors face the rudder blade 110 through the measuring windows.

[0027] The utility model clamps the servo by the first clamp 50 and the second clamp 60, and limits the position by the positioning member. When the servo blade of the servo is deflected from the initial position to the set deflection position, the first measuring member 70 and the second measuring member 80 respectively measure the multiple servo blades 110 on the circumference of the servo 100 at the same time, and the deflection distance of each servo blade 110 relative to the initial position can be detected, so as to judge the deflection polarity, and finally compare it with the set polarity, so as to detect the deflection polarity and verify whether the deflection polarity is correct.

[0028] like Figure 2 As shown, the first measuring member 70 in this embodiment has two measuring windows, because the steering gear 100 in this embodiment has four rudder blades 110, and there are two rudder blades distributed within the measuring range of the first measuring member 70. Moreover, the shape of the first measuring member 70 also needs to be matched according to the shape of the steering gear 110, so as to ensure that when the deflection polarity of the rudder blades 110 is consistent, the data measured by each measuring sensor is equal, avoiding the need for subsequent calculation.

[0029] In the embodiment of the present invention, multiple measuring sensors are located on the same cross section of the steering gear 100, so that the distance values ​​measured by each measuring sensor are all distance values ​​on the same cross section, which can increase the measurement accuracy. Specifically, the measuring sensor can be a laser distance measuring sensor. After measuring the distance, the deflection distance of each rudder blade relative to the initial position can be calculated, and finally compared with the predetermined deflection distance to obtain its deflection polarity.

[0030] In one embodiment, the first fixture 50 and the second fixture 60 are coaxially arranged, and the axes of the two are perpendicular to the cross section of the steering gear 100 where the measuring sensor is located. Such an arrangement can ensure that the steering gear 100 is level and at a predetermined height, thereby ensuring the measurement accuracy when measuring the upper and lower measuring pieces.

[0031] In another embodiment, different sizes of fixtures can be installed on the slider to adapt to the measurement of steering gears of different sizes. In addition, a bracket can be added to the slider, and multiple detachable fixtures can be installed on the bracket at the same time. When measurement is required, a fixture of a corresponding size is selected according to the size of the steering gear 100 and installed on the bracket.

[0032] As a specific implementation, both ends of the first clamp 50 are respectively mounted on the first slider 30 and the second slider 40 which are arranged in parallel; both ends of the second clamp 60 are respectively mounted on the first slider 30 and the second slider 40 which are arranged in parallel. The first slider 30 is mounted on the first slide rail 10; the second slider 40 is mounted on the second slide rail 20; the first slide rail 10 and the second slide rail 20 are arranged in parallel.

[0033] The two fixtures can be translated by the cooperation of the slider and the slide rail. When the steering gear 100 needs to be installed, the fixture is translated out of the space of the measuring piece for easy operation. After the installation is completed, it is moved to the measuring position for measurement.

[0034] In addition, a positioning member 51 is provided on the first fixture 50 or the second fixture 60, and the positioning member 51 is used to cooperate with the positioning groove on the steering gear 100 to realize the circumferential positioning of the steering gear 100. Figure 3 As shown, in this embodiment, an additional positioning piece is installed on the first clamp 50, and a positioning member 51 extends from the positioning piece to the inside of the clamp. In this embodiment, the positioning member 51 is in a strip shape. The positioning member 51 cooperates with the positioning groove on the steering gear 100 to achieve the circumferential position fixation of the steering gear 100.

[0035] As a specific implementation, the first measuring member 70 and the second measuring member 80 are mounted on the same fixing frame 90; a limiting device is provided on the fixing frame 90. The limiting device can be various, such as a limiting plate, and when the first fixture 50 moves toward the fixing frame 90 and reaches the position of the limiting plate, it stops moving, and at this time, the rudder blade 110 is exactly located at the position to be detected.

[0036] The method of using the utility model is:

[0037] like Figure 4 As shown, the first clamp 50 and the second clamp 60 are clamped to the outer periphery of the front and rear ends of the steering gear 100 respectively. When installing the steering gear 100, it is necessary to pay attention to the position correspondence between its positioning groove and the positioning piece 51 on the first clamp 50. After clamping the steering gear 100, slide the clamp and the steering gear 100 together toward the fixing frame 90 until the front end of the first clamp 50 contacts the limit plate of the fixing frame and stops. At this time, the four steering blades are all in the position to be measured.

[0038] Then, the measuring device is started to synchronously measure the four rudder blades to obtain the distance value between each rudder blade 110 and the measuring sensor, thereby obtaining the deflection distance of the rudder blade relative to the initial position. After the measurement is completed, the fixture and the steering gear 100 are moved to the initial position, the steering gear is disassembled, and the measurement is completed.
