Technical Field

[0001] This utility model relates to the field of aircraft manufacturing technology, and in particular to a processing device for mounting bearings on aircraft transmission support joint parts. Background Technology

[0002] In aircraft design and manufacturing, the installation of mating bearings at the transmission support joint is crucial. Traditional bearing installation methods have some shortcomings, such as difficulty in ensuring installation accuracy, which can easily lead to problems such as bearing eccentricity and jamming during operation, thereby affecting the normal transmission and service life of aircraft components.

[0003] The above problems can be solved by using flanged self-lubricating bearings. However, in the flanging process of parts, the traditional method of mounting and processing bearings is complicated and inefficient, which increases the cost and cycle of aircraft manufacturing. Utility Model Content

[0004] The main purpose of this utility model is to propose a processing device for mounting bearings on aircraft transmission support joint parts, aiming to solve the technical problems of complex operation and low efficiency in the traditional installation and processing methods for mounting bearings on aircraft transmission support joint parts.

[0005] To achieve the above objectives, the present invention proposes a processing device for the bearing assembly of an aircraft transmission support joint part, which can be used in conjunction with a drilling machine to flange the bearing of the part. The processing device includes: A rolling mechanism includes a main shaft and at least one rolling wheel rotatably connected to the main shaft, for rolling the bearing of the aircraft transmission support joint part when the main shaft rotates; The support mechanism includes a support base and a bearing mounting base disposed on the support base, for supporting the bearing assembly of the aircraft transmission support joint parts.

[0006] Optionally, the rolling mechanism further includes a first washer disposed on the inner side of the rolling roller, used to adjust the distance between the rolling roller and the main shaft.

[0007] Optionally, the rolling mechanism further includes a mandrel and a second washer, the second washer being disposed on the outside of the rolling roller, and the mandrel being sequentially connected to the second washer, the rolling roller, the first washer, and the main shaft.

[0008] Optionally, two of each of the mandrel, the second washer, the rolling roller, and the first washer are provided and symmetrically arranged on both sides of the main shaft.

[0009] Optionally, the rolling surface of the rolling roller is set at a horizontal inclination of 65°.

[0010] Optionally, the bearing mounting base includes a first mounting base and a second mounting base, which are respectively used to support the first and second surfaces of the bearings mounted on the aircraft transmission support joint parts.

[0011] Optionally, the surfaces of the first and second mounting seats respectively match the first and second surfaces of the bearings of the aircraft transmission support joint parts.

[0012] Optionally, it also includes a linkage mechanism, which includes a connecting rod connected to the main shaft, for ensuring coaxiality between the two mating bearings when the second side of the mating bearing is flanged.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0025] Please see Figure 2 , Figure 2 For the assembly of bearings in aircraft transmission support joints, the traditional installation and fixing methods are complicated due to the special structure, resulting in complicated and inefficient installation and processing methods, which increases the cost and cycle of aircraft manufacturing.

[0026] In view of this, the present invention provides a processing device for mating bearings of aircraft transmission support joint parts. This device, in conjunction with a drilling machine, especially a radial drilling machine, is used to flange the mating bearings of aircraft transmission support joint parts. Figure 1 , 3 -6 is an embodiment of the processing device for mounting bearings on aircraft transmission support joint parts provided by this utility model. Please refer to [link / reference]. Figure 1 , 3 -6. The processing device 100 includes a rolling mechanism 1 and a support mechanism 2.

[0027] Specifically, the rolling mechanism 1 includes a main shaft 11 and two rolling rollers 12 connected to the main shaft 11. The main shaft 11 is a cylindrical rotating body structure. In use, the main shaft 11 can be partially inserted into the bearing hole and the support mechanism 2. The two rolling rollers 12 are symmetrically installed on the side of the main shaft 11 and are located near the middle of the main shaft 11. The rolling rollers 12 can be installed by bolts, riveting, or other connection methods. There is a movable gap between the rolling rollers 12 and the main shaft 11 so that the rolling rollers 12 can rotate on the bolts or rivets.

[0028] Please see Figure 3-5 When the radial drilling machine 300 drives the spindle 11 to rotate, the rolling roller 12 can roll the surface of the bearing 201 mounted on the aircraft transmission support joint part. Through the downward pressure of the radial drilling machine 300, the rolling surface of the rolling roller 12 presses against the inner periphery of the bearing 201, causing its outer periphery to adhere tightly to the part 200. It should be understood that the rolling roller 12 can rotate and roll circumferentially along the inner periphery of one side surface of the bearing 201 under a certain frictional force, simultaneously pressing against the inner periphery of the bearing 201. During use, lubricating oil needs to be applied to the rollers of the rolling mechanism 1. The rollers are made of W18Cr4V material to ensure their strength and wear resistance.

[0029] Please see Figure 1The support mechanism 2 includes a support base 21 and a bearing mounting base 22 disposed on the support base 21. The support base 21 is generally rectangular and can be placed relatively stably and horizontally on the worktable of the drilling machine 300. The bearing mounting base 22 is placed horizontally above the support base 21 to support the bearing 201 of the aircraft transmission support joint part. Limiting holes (not shown in the figure) are provided in both the support base 21 and the bearing mounting base 22. A portion of the spindle 11 can pass through the bearing hole (not shown in the figure) of the aircraft transmission support joint part 200 and be inserted into the lower limiting hole to limit the spindle 11. A small gap exists between the spindle 11, the bearing hole, and each limiting hole to allow the spindle 11 to rotate within the holes. It should be noted that the support base 21 has a central groove (not shown in the figure) to avoid interference with the parts. The support base is made of ordinary Q235 material to save costs.

[0030] In the technical solution of this utility model, the aircraft transmission support joint part mating bearing 201 is placed on the bearing mounting seat 22. The main shaft 11 of the rolling mechanism 1 is clamped by the radial drilling machine 300, and the rolling roller 12 connected to the main shaft 11 is driven to slowly press down on the surface of one of the bearings of the aircraft transmission support joint part mating bearing 201. The main shaft 11 is rotated so that the two rolling rollers 12 roll until the edge of the bearing 201 is in contact with the part 200, thus completing the flanging of one side of the bearing 201. The method of using this device is simple and easy to implement and convenient to operate, which can greatly improve the processing efficiency and reduce the cost and cycle of aircraft manufacturing.

[0031] The cooperation between the spindle 11 and the bearing mounting base 22 can effectively ensure the machining accuracy and reliability of the bearing, avoid problems such as eccentricity and jamming that are easy to occur in traditional installation methods, improve the transmission efficiency and service life of aircraft components, and is suitable for the installation of self-lubricating bearings in various types of aircraft transmission support joint parts, with broad application prospects.

[0032] To enable the rolling roller 12 of the rolling mechanism 1 to process the bearing 201 of aircraft transmission support joint parts of different sizes, please refer to... Figure 1 and 6 In one embodiment of this utility model, the rolling mechanism 1 further includes a first washer 13. The first washer 13 is disposed on the inner side of the rolling roller 12 and is located between the rolling roller 12 and the main shaft 11. By replacing the first washer 13 with one of different thicknesses and then fixing the rolling roller 12, the distance between the rolling roller 12 and the main shaft 11 can be adjusted, thereby adjusting the spacing between the two rolling rollers 12 so that they can roll and flang the bearings 201 of different sizes.

[0033] For better fixation of the rolling roller 12 and adjustment of the spacing of the rolling roller 12, please refer to [link / reference]. Figure 1 and 6In one embodiment of this utility model, the rolling mechanism 1 further includes a mandrel 14 and a second washer 15. The second washer 15 is disposed on the outer side of the rolling roller 12. The mandrel 14 is sequentially connected to the second washer 15, the rolling roller 12, the first washer 13, and the center hole of the main shaft 11. The first washer 13 of other thicknesses can be replaced by disassembling the mandrel 14. Specifically, the mandrel 14 is an M4 specification semi-circular head hexagonal socket screw, which is connected to the internal thread hole of the main shaft 11 through its external thread. The rolling roller 12 can rotate around the mandrel 14, and the rotating parts of the mandrel 14 and the rolling roller 12 are not threaded.

[0034] To improve rolling efficiency and balance, please refer to [link / reference]. Figure 1 and 6 In one embodiment of this utility model, the mandrel 14, the second washer 15, the rolling roller 12, and the first washer 13 are each provided in duplicate and symmetrically arranged on both sides of the main shaft 11. By providing two symmetrical rolling rollers 12, the pressure on the bearing 201 of the part can be more even, and warping can be prevented. Furthermore, the flanging efficiency of multiple rolling rollers 12 is greatly improved. Of course, rolling can also be performed with only one rolling roller.

[0035] For better compatibility with bearing 201, please refer to [link / reference]. Figure 1 and 6 In one embodiment of the present invention, the rolling surface 121 of the rolling roller 12 is set at a horizontal inclination of 65°. When the bearing surface of the part bearing 201 is horizontal relative to the worktable of the drilling machine 300, the rolling surface at this angle can better contact the inner periphery of the bearing 201 surface and squeeze the edge to make the outer periphery of the bearing 201 fit with the part 200.

[0036] Because the contours of the two outer and two inner sides of the bearing 201 in the aircraft transmission support joint are different, please refer to... Figure 1 , 3 -5. In one embodiment of the present invention, the bearing mounting base 22 includes a first mounting base 221 and a second mounting base 222. The first mounting base 221 is used to support the first surface 2011 (i.e., the two outer surfaces) of the bearing 201 mounted on the aircraft transmission support joint parts, and the second mounting base 222 is used to support the second surface 2012 (i.e., the two inner surfaces) of the bearing 201 mounted on the aircraft transmission support joint parts.

[0037] Furthermore, the surfaces of the first mounting base 221 and the second mounting base 222 are respectively matched with the first surface 2011 and the second surface 2012 of the bearing 201 of the aircraft transmission support joint part to achieve stable support during the rolling and flanging process.

[0038] To ensure that the second surface 2012 of the bearing 201 in the aircraft transmission support joint component maintains its coaxiality during flanging, please refer to... Figure 1, 4 5. In one embodiment of the present invention, the processing device 100 further includes a linkage mechanism 3. The linkage mechanism 3 includes a connecting rod 31 connected to the main shaft 11. The connecting rod 31 can extend the length of the main shaft 11. When the rolling wheel on the main shaft 11 flangs the second surface 2012 (i.e., the inner surface) of one of the bearings 201, the other bearing can be fitted onto the connecting rod 31. The connecting rod 31 and the main shaft 11 are coaxially arranged to ensure the coaxiality between the two bearings 201.

[0039] Further, please refer to Figure 1 and 6 The linkage mechanism 3 also includes a positioning pin 32. The end of the connecting rod 31 is sleeved on the end of the main shaft 11, and then the positioning pin 32 is horizontally inserted into the hole of the connecting rod 31 and the main shaft 11 so that the two can be kept relatively fixed. This connection structure allows the linkage mechanism 3 to be used with rolling mechanisms 1 of other sizes.

[0040] In a preferred embodiment, the bearing 201 of the aircraft transmission support joint is a self-lubricating bearing. A self-lubricating bearing is a mechanical component that achieves oil-free or low-oil lubrication using solid lubricating materials, effectively reducing mechanical vibration and noise. When rolling the inner circumference of the self-lubricating bearing, a feeler gauge is used to check the clearance. If the clearance is too large, multiple rolling passes are allowed until the clearance meets the requirements. This avoids scrap and rework due to misjudgment, improving product quality and the efficiency of batch production.

[0041] When this processing device 100 is used in conjunction with a radial drilling machine, the specific processing steps are as follows: S1. Connect the main shaft 11, spindle 14, second washer 15, rolling roller 12 and first washer 13, and lock the thread of the spindle 14 with the main shaft 11 to assemble a rolling mechanism, ensuring that the rolling roller 24 can rotate flexibly, and clean the rolling roller 12 to ensure that there are no foreign objects in the parts in contact with the parts. S2. Fix the rolling mechanism 1 to the spindle of the radial drilling machine; S3. Confirm the spindle speed of the radial drilling machine is 50 rpm-300 rpm; S4. Turn on the radial drilling machine and confirm that the clamping is stable. S5. Without starting the equipment, clamp the radial drilling machine and gently press the rolling mechanism 1 downwards to ensure connection with the bearing mounting seat 22. Slowly place the bearing mounting seat 22 into the support surface groove of the support seat 2. S6. Place part 200 on bearing mounting base 221, clean bearing mounting base 221, and ensure that there are no foreign objects in the parts that come into contact with the part; S7. Start the equipment, apply lubricating oil to the rolling roller 12, slowly press the spindle of the radial drilling machine down to roll the outer side of the bearing until the bearing edge is in contact with the part, slowly lift the spindle up and turn off the equipment. S8. Clean the oil stains, rotate the machine transmission support joint parts 180°, and repeat steps S6 and S7. S9. Remove the rolling mechanism 1 from the radial drilling machine; S10. Fix the connecting rod 31 on the spindle of the radial drilling machine, and set the spindle speed of the machine tool to 50 rpm; S11. Pass the connecting rod 31 through the center of one of the bearings that has been flipped over in the aircraft transmission support joint parts, and further connect it to the rolling mechanism 1. Fix it with the positioning pin 32 to ensure coaxiality after the equipment is started after connection. S12. Without starting the equipment, clamp the radial drilling machine and gently press the rolling device downwards to ensure connection with the bearing mounting seat 222. Slowly place the bearing mounting seat 222 into the support surface groove of the support seat 21. S13. Place the part on the bearing mounting seat 222, clean the bearing mounting seat 222, and ensure that there are no foreign objects in the parts that come into contact with the part; S14. Start the equipment, apply lubricating oil to the rolling roller 12, slowly press the spindle of the radial drilling machine down to roll the inner side of the bearing until the bearing edge is in contact with the part, slowly lift the spindle up and turn off the equipment. S15. Pull out the positioning pin 32, remove the rolling mechanism 1, clean the oil stains on the parts, rotate the machine transmission support joint parts 180°, and repeat steps S11 to S14. S16. Further pull out the locating pin 32, remove the rolling mechanism 1, clean the oil stains on the parts, and use a 0.127mm feeler gauge to check the clearance of the aircraft transmission support joint parts after rolling. It is allowed to exceed the requirement by up to 40%. If it is not qualified, step 14 can be repeated to ensure that the clearance check is met and the bearing can rotate flexibly.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
