Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of aircraft manufacturing, especially to a kind of adjusting tool. BACKGROUND

[0002] When the gap between the aileron and the structure around it is checked, the aileron needs to be in zero position. The zero position of the aileron is the height difference between the upper surface of the aileron and the upper surface of the aileron compartment. However, the aileron is controlled by the pressure of the hydraulic system. When the engine of the aircraft is not started, the hydraulic system cannot press the actuator of the aileron, and the actuator of the aileron has no self-locking function. Therefore, when the engine of the aircraft is not started, the aileron will naturally deflect downward around its suspension axis. When adjusting the aileron to zero position, a worker needs to hold the aileron in a horizontal position in real time, and another worker needs to measure the height difference between the upper surface of the aileron compartment and the upper surface of the aileron in real time, and adjust the height of the aileron according to the measured height difference to make the height difference between the two upper surfaces meet the specified difference. At this time, the aileron is adjusted to zero position. Since the aileron is a movable part, the manual lifting method cannot guarantee that the aileron is always in a horizontal position, so the accuracy of the zero position of the aileron is affected, which further affects the accuracy of the gap measurement between the aileron and the surrounding structure. At the same time, the adjustment of the zero position of the aileron requires the cooperation of two people, which wastes labor to some extent.

[0003] Therefore, there is an urgent need for an adjusting tool to solve the above technical problems. INVENTION CONTENTS

The measuring assembly 3 is connected with the main body 1 and is configured to measure the height difference between the upper surface of the aileron cabin 100 and the upper surface of the aileron 200. Since the main body 1 is provided with the avoiding opening 12 connecting the two accommodating grooves 11, when the aileron cabin 100 and the aileron 200 are arranged in the two accommodating grooves 11, part of the aileron 200 and the aileron cabin 100 are arranged at the avoiding opening 12, after the measuring assembly 3 abuts against the upper surface of the aileron cabin 100, a data is obtained, then the staff can take down the measuring assembly 3 and assemble it to a position opposite to the aileron 200 on the main body 1, after the measuring assembly 3 abuts against the upper surface of the aileron 200, a second data is obtained, the difference between the two data is the height difference between the upper surface of the aileron cabin 100 and the upper surface of the aileron 200, then the staff can adjust the height of the aileron 200 by using the clamping assembly 2 lifting the aileron 200 according to the height difference between the two, so as to adjust the aileron 200 to zero position. In the embodiment, the first direction is the direction of the X axis.

[0034] The adjusting tool provided by the embodiment can place the aileron cabin 100 and the aileron 200 in the two accommodating grooves 11 respectively, and the part of the aileron cabin 100 and the aileron 200 can be placed in the avoiding opening 12, so that the measuring assembly 3 can measure the height difference between the upper surface of the aileron cabin 100 and the upper surface of the aileron 200. The aileron cabin 100 is lifted by the clamping assembly 2 corresponding to the accommodating groove 11 accommodating the aileron cabin 100, and the aileron 200 is connected with the aileron cabin 100. After the clamping assembly 2 clamps the aileron cabin 100, the aileron 200 is always in a horizontal state under the driving of the aileron cabin 100, so that the accuracy of the zero position state of the aileron 200 is ensured, and the accuracy of the clearance detection between the aileron 200 and the surrounding components is ensured. At the same time, the artificial lifting is avoided, and the zero position state adjustment of the aileron 200 can be completed by only one worker, so that the labor is released.

[0035] Exemplarily, the clamping assembly 2 comprises a clamp 21, a movable plate 22 and a driving member 23. The clamp 21 comprises a first clamping member 211 and a second clamping member 212. The first clamping member 211 is connected with one end surface of the accommodating groove 11 and is arranged in the accommodating groove 11. The movable plate 22 is arranged in the accommodating groove 11 and is provided with the second clamping member 212 on the surface opposite to the first clamping member 211. The driving member 23 is arranged on one end surface of the accommodating groove 11 and is connected with the movable plate 22. The driving member 23 can drive the movable plate 22 to move towards the first clamping member 211, so that the second clamping member 212 on the movable plate 22 moves towards the first clamping member 211. In order to facilitate the description, in the embodiment, the accommodating groove 11 accommodating the aileron cabin 100 is referred to as a first accommodating groove, the accommodating groove 11 accommodating the aileron 200 is referred to as a second accommodating groove, the clamping assembly 2 clamping the aileron cabin 100 is referred to as a first clamping assembly, and the clamping assembly 2 lifting the aileron 200 is referred to as a second clamping assembly. Specifically, the aileron cabin 100 is arranged between the first clamping member 211 and the second clamping member 212 in the first clamping assembly, and the aileron cabin 100 is clamped by the first clamping member 211 and the second clamping member 212, so that the aileron 200 is driven to be in a horizontal state. The aileron 200 is attached to the second clamping member 212 in the second clamping assembly, and the height of the movable plate 22 in the second clamping assembly can be controlled by driving the driving member 23 in the second clamping assembly, so that the height of the aileron 200 can be adjusted.

[0036] Further, the first assembly hole is arranged at one end face of the accommodating groove 11, the driving member 23 comprises a bearing 231 and a screw rod 232, the bearing 231 is arranged in the first assembly hole, that is, the bearing 231 is clamped in the first assembly hole, the screw rod 232 is arranged in the inner ring of the bearing 231 and is arranged in the accommodating groove 11, the screw rod 232 is fixed with the inner ring of the bearing 231, and the movable plate 22 is threadedly connected with the screw rod 232. In this way, by rotating the screw rod 232 in the forward direction or the reverse direction, the height of the movable plate 22 can be adjusted, so that the movable plate 22 is close to or away from the first clamping member 211, the height of the aileron 200 is adjusted, and the aileron 200 is adjusted to the zero position according to the height difference between the upper surface height of the aileron cabin 100 and the upper surface height of the aileron 200 measured by the measuring assembly 3.

[0037] As preferred, the driving member 23 further comprises a connecting rod 233, the connecting rod 233 is connected with one end of the screw rod 232 away from the accommodating groove 11, so that it is more convenient for the staff to rotate the screw rod 232 and control the rotation range of the screw rod 232. Specifically, an opening is arranged at one end of the screw rod 232 away from the accommodating groove 11, and the connecting rod 233 is arranged in the opening, so that the connecting rod 233 is connected with the screw rod 232.

[0038] As preferred, the first clamping member 211 and the second clamping member 212 are both conical rubber suction cups. In this way, for the first clamping assembly, the contact area of the first clamping member 211 and the second clamping member 212 with the aileron cabin 100 can be increased, so that the aileron cabin 100 is clamped more stably. For the second clamping assembly, the contact area of the second clamping member 212 and the aileron 200 can be increased, so that the aileron 200 is clamped more stably. At the same time, the rubber material can protect the paint layer on the aileron cabin 100 and the aileron 200.

[0039] Further, the clamping assembly 2 further comprises a guide member 24 and a fastening member 25, the guide member 24 penetrates through the accommodating groove 11 and the movable plate 22 and is located at one side of the driving member 23, and the fastening member 25 is used for fixing the guide member 24 with the end face of the accommodating groove 11. In this way, when the staff rotates the screw rod 232 to make the movable plate 22 move up and down, the movable plate 22 will move along the guide member 24, the guide member 24 plays a guiding role in the up and down movement of the movable plate 22, so that the problem of deviation of the movable plate 22 in the up and down movement is avoided, and the accuracy of the adjustment of the aileron 200 is ensured.

[0040] Exemplarily, as shown in FIG. 6, the first clamping member 211 and the second clamping member 212 are both conical rubber suction cups. Figure 1 and Figure 4As shown in the figure, the measuring assembly 3 comprises a first fitting part 31, a second fitting part 32, a measuring instrument 33 and a fixing part 34. The first fitting part 31 comprises a first folding edge 311 and a second folding edge 312 which are perpendicular to each other. The fixing part 34 is used to fix the first folding edge 311 to the upper end surface of the accommodating groove 11, and the second folding edge 312 faces away from the accommodating groove 11. The position of the first fitting part 31 along the first direction is adjustable. The second fitting part 32 is connected to the second folding edge 312 through the fixing part 34, and the position of the second fitting part 32 along the height direction is adjustable. The measuring instrument 33 is connected to the second fitting part 32. Since the position of the first fitting part 31 along the first direction is adjustable, i.e. the position of the measuring instrument 33 along the first direction is adjustable, the aileron 200 can be measured at multiple positions along the first direction. If the multiple measurement data measured by the measuring instrument 33 are consistent, the aileron 200 is in a horizontal state. If the multiple measurement data measured by the measuring instrument 33 are inconsistent, the aileron 200 is not adjusted to the horizontal state, and the staff needs to adjust the levelness of the aileron 200. The position of the second fitting part 32 along the height direction is adjustable, i.e. the position of the measuring instrument 33 along the height direction is adjustable, so that the measuring instrument 33 can abut against the aileron cabin 100 or the aileron 200.

[0041] Specifically, the upper end surface of the accommodating groove 11 is provided with a second fitting hole, and the first folding edge 311 is provided with a first strip-shaped hole 3111. The fixing part 34 is locked in the second fitting hole after passing through the first strip-shaped hole 3111. The staff can lock the different positions of the first strip-shaped hole 3111 and the second fitting hole through the fixing part 34, so as to adjust the position of the first fitting part 31 along the first direction, and further adjust the position of the measuring instrument 33 along the first direction. The fixing part 34 can be a bolt, the bolt is provided with external threads, the second fitting hole is provided with internal threads, and the external threads of the periphery of the bolt are screwed with the internal threads of the second fitting hole after the bolt passes through the first strip-shaped hole 3111, so as to be locked in the second fitting hole.

[0042] Specifically, the second folding edge 312 is provided with a second strip-shaped hole 3121, and the second fitting part 32 comprises a third folding edge 321 and a fourth folding edge 322 which are perpendicular to each other. The third folding edge 321 is provided with a fixing hole, and the fixing part 34 is locked in the fixing hole after passing through the second strip-shaped hole 3121. The measuring instrument 33 is connected to the fourth folding edge 322. The staff can lock the fixing hole on the third folding edge 321 and the different positions of the second strip-shaped hole 3121, so as to adjust the position of the second fitting part 32 along the height direction, and further adjust the position of the measuring instrument 33 along the height direction. The third folding edge 321 and the fourth folding edge 322 are perpendicular to each other, so that the measuring instrument 33 always vertically faces the aileron 200 and the aileron cabin 100 during the movement along the height direction, i.e. the up and down movement, to ensure the accuracy of the measurement data.

[0043] In the embodiment, the measuring instrument 33 is a surface difference ruler. The surface difference ruler is a commonly used measuring tool in the measuring field, and its specific structure and working principle can refer to the prior art, and will not be described in detail here.
