DETAILED DESCRIPTION

[0032] In response to the drawbacks, deficiencies, and numerous limitations of existing technologies, the applicant has developed a device and method for translating the aileron's rotation axis. This device achieves this goal of translating the aileron's rotation axis toward the rearward side of the aircraft's heading, avoiding the waste of resources associated with manufacturing large tooling and reducing the time wasted disassembling aircraft components. The invention also provides a solution for repairing similar structures.

[0033] In combination with product structure and modification requirements, a lightweight and efficient joint axis translation device has been invented, which can realize the axis translation of the aileron mounting joint on the aircraft and ensure the coaxiality requirements of the three aileron mounting joints.

[0034] like Figure 1-4 The device for translating the rotation axis of an aircraft aileron includes a support body, a joint axis position converter, and an auxiliary positioning body.

[0035] The support body includes an I-shaped material 1 and three pads 2.

[0036] The I-shaped section 1, the main support structure, is made of aluminum alloy and is 6mm thick. Multiple (e.g., eight) oblong lightening holes are cut into the vertical beams of the I-shaped section. Three pairs of columns are welded to the I-shaped section at the three joint replacement areas. Three steel pads 2 are mounted on the I-shaped section. These pads are located in the three working areas of the device, enhancing rigidity. Reference holes for laser measurement are provided on the pads at each end of the device.

[0037] The joint axis position converter includes a joint locator support 3, a new joint locator 4-1 at the first joint, an old joint locator 4-2 at the first joint, a new joint locator 10-1 at the second joint, an old joint locator 10-2 at the second joint, a new joint locator 11 at the third joint, a movable pin 5, and a positioning bolt 6.

[0038] The joint locator support 3 is an L-shaped structure composed of welded horizontal and vertical plates, specifically aluminum plates, and is mounted to the support using bolts and locating pins. Preferably, vertical ribs are provided on the back of the vertical plates to support the L-shaped structure and provide greater stability. The vertical plates are provided with at least a first locator mounting hole and a second locator mounting hole.

[0039] The joint locator is the primary component for achieving axial translation of the aileron mounting joint. At the first and second joints, there are two joint locators in each group (new joint locator 4-1 at the first joint, old joint locator 4-2 at the first joint). The second joint locator consists of two locators (new joint locator 10-1 at the second joint, old joint locator 10-2 at the second joint). Each group of two locators is used to locate the new and old joints, respectively. The mounting holes on the support for each group of two locators are located in the same position, but the joint locating holes are located in different positions. At the third joint, there is only one joint locator (new joint locator 11 at the third joint), which only locates the new joint. The locators are all made of aluminum, and the locating holes measured by the laser tracker are machined during manufacturing.

[0040] The movable pin 5 is used to position the joint on the joint positioner (new joint positioner 4-1 at the first joint, old joint positioner 4-2 at the first joint, new joint positioner 10-1 at the second joint, old joint positioner 10-2 at the second joint, new joint positioner 11 at the third joint).

[0041] The positioning bolts are used to connect the joint positioners (new joint positioner 4-1 at the first joint, old joint positioner 4-2 at the first joint, new joint positioner 10-1 at the second joint, old joint positioner 10-2 at the second joint, new joint positioner 11 at the third joint) and the joint positioner support 3.

[0042] The auxiliary positioning body includes an auxiliary positioning body support 9, a positioning member 7, a clamping plate 8, a positioning bolt 6 and corresponding connecting standard parts.

[0043] The auxiliary positioning body support 9 is an L-shaped structure welded by a horizontal plate and a vertical plate, which can be specifically welded by aluminum plates and mounted on the support body with bolts and positioning pins. Preferably, vertical ribs are provided on the back of the vertical plate to support the L-shaped structure for greater stability.

[0044] The positioning member 7 comprises an L-shaped structure formed by welding a horizontal plate (positioning plate) and a vertical plate (connecting plate). Specifically, it can be welded from aluminum plates. An iron plate is bonded to the positioning surface of the horizontal plate to assist in positioning the device. The vertical plate (connecting plate) of the positioning member 7 has an oblong hole and is mounted on the auxiliary positioning body support 9 with positioning bolts. The positioning member 7 is made of aluminum and has positioning holes machined into it during manufacturing for laser measurement.

[0045] The clamping plate 8 is made of a strong magnetic material and can form an attractive force with the iron plate on the positioning member 7 when the device is positioned, so as to clamp the parts.

[0046] The joint locator support 3 and the auxiliary positioning body support 9 are connected to the support body with gaskets 12 to adjust the height. This device is assembled using a laser tracker to ensure that the coaxiality of the three joint locators is no more than 0.1mm, and at the same time ensure the spatial position relationship between the auxiliary positioning surface and the aileron mounting joint.

[0047] The specific implementation method is:

[0048] The first step is to make the position converters of the joint axis of the device numbered 4-2, 10-2, 11 ( Figure 1 (Part numbers in the table, the same below).

[0049] Step 2, Figure 4 As shown, first remove the old joint at the third joint, then use the first joint and the second joint to position the device on the body, press the positioning surface of the auxiliary positioning body against the beam plane, tighten the positioning bolts at the oblong hole, and use the magnetic attraction of the splint to clamp the beam parts.

[0050] Step 3: Use joint axis position converter 11 to locate and install the new third joint. Next, remove joint axis position converter 4-2, install joint axis position converter 4-1, locate and install the new first joint. Remove joint axis position converter 10-2, install joint axis position converter 10-1, locate and install the new second joint.

[0051] Step 4: At this point, the aileron rotation axis has been moved horizontally toward the heading, and the device can be disassembled.

[0054] Step 2: Remove the third old connector;

[0055] Step 3: Install the third new joint: connect the new joint locator 11 at the third joint to the third joint locator support 3 and the third new joint through the locator installation hole and the structure positioning hole respectively;

[0060] During the process of removing any old joint or installing any new joint, the other two joint positions are positioned by the auxiliary positioning bodies.

[0061] This device has a simple structure and is easy to operate. Its main structure consists of a support body, a joint axis position converter, and an auxiliary positioning body. During operation, the device is positioned by utilizing the relative positional relationship between the axis translation joints. The auxiliary positioning body assists in positioning the device accurately, allowing the replacement of old joints with new ones to achieve aileron axis translation.
