Technical Field

[0001] This utility model relates to the field of aviation repair, specifically a self-locking nut machine on a pallet for in-situ closing repair. Background Technology

[0002] To facilitate the installation and removal of the cover, and to meet requirements such as anti-loosening and vibration resistance, self-locking nuts for mounting plates are widely used on aircraft. However, after long-term use, it has been found that many of these self-locking nuts have experienced locking failure. Currently, repairs are mainly done by replacement, which is a labor-intensive process and may damage the rivet holes used to install the self-locking nuts.

[0003] Therefore, there is a need for a device that can reduce the troubleshooting time of replacing the self-locking nut of the pallet by performing on-site repair of the self-locking nut of the pallet after the self-locking part fails, and reduce the damage to the installation structure when disassembling and assembling the self-locking nut of the pallet and installing rivets.

[0006] The operating end includes a closing nozzle, a closing cylinder, a closing handle, and a hydraulic oil pipe connected in sequence.

[0007] The power unit includes a hydraulic oil pipe joint, a pneumatic hydraulic pump, and an air source joint connected in sequence.

[0008] The nozzle includes a forming guide mechanism, a drive connecting block disposed inside the forming guide mechanism, a forming blade that cooperates with the drive connecting block via a connecting pin one, and a drive connecting rod that cooperates with the drive connecting block via a connecting pin two.

[0009] The molding guide mechanism is specifically the molding guide mechanism housing.

[0010] The housing of the forming guide mechanism is divided into a forming area and a limiting area.

[0011] The beneficial effects of this utility model are:

[0012] This invention enables on-site repair of self-locking nuts on pallets that have failed to lock properly. To use, connect compressed air, align the device with the self-locking nut requiring repair, press the button, and the repair is complete. It is convenient and easy to operate.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0020] like Figures 1 to 3 As shown, an in-situ closing repair device for a self-locking nut machine includes an operating end and a power end, which are connected by a hydraulic oil pipe 4. The power end is placed in a stable position, and the operating end can be moved at will to realize repair work within the radius of the hydraulic oil pipe length.

[0021] The operating end includes a closing gun head 1, a closing cylinder body 2, a closing handle 3, and a hydraulic oil pipe 4 connected in sequence;

[0022] The power unit includes a hydraulic oil pipe connector 5, a pneumatic hydraulic pump 6, and an air source connector 7 connected in sequence.

[0023] like Figure 3 As shown, the end-closing gun head 1 of this utility model includes a forming guide mechanism, a drive connecting block 11 disposed inside the forming guide mechanism, a forming blade 9 that cooperates with the drive connecting block 11 through a connecting pin 10, and a drive connecting rod 13 that cooperates with the drive connecting block 11 through a connecting pin 2. After receiving the force transmitted by the end-closing cylinder 2, the drive connecting rod 13 drives the forming blade 9 and the drive connecting block 11 to move back and forth, thereby realizing the end-closing repair work.

[0024] The molding guide mechanism is specifically the molding guide mechanism housing 15.

[0025] Specifically, such as Figure 3 As shown, as an optimized solution, the molding guide mechanism housing 15 of this utility model is divided into a molding guide mechanism molding area 8 and a molding guide mechanism limiting area 12. The molding guide mechanism, composed of the molding guide mechanism molding area 8, the molding guide mechanism limiting area 12, and the molding guide mechanism housing 15, is the fixed part of the nozzle head 1. It forms a cavity structure inside to allow the drive connecting block 11 to move back and forth.

[0026] The forming guide mechanism of this utility model has a forming area 8 for limiting the movement trajectory of the forming blade 9 and together with the forming blade 9, it controls the closing size and closing height; the forming guide mechanism has a limiting area 12 for limiting the movement limit position of the drive connecting block 11.

[0027] As a further optimization of this utility model, the driving method adopted by this utility model is compressed air drive.

[0028] The closing gun head 1 can control the closing size, closing height, and 360° rotation, realizing the closing repair of self-locking nuts of different sizes of pallets. By rotating the closing gun head 1, the closing repair of self-locking nuts of pallets in various spatial positions can be conveniently operated. The forming area thickness of the closing gun head 1 is only 15mm, and it is not on the same axis as the drive part, which can realize the in-situ closing repair of self-locking nuts of pallets installed in the gap area on the machine.

[0029] This invention enables on-site repair of self-locking nuts on pallets that have failed to lock properly. To use, connect compressed air, align the device with the self-locking nut requiring repair, press the button, and the repair is complete. It is convenient and easy to operate.

[0030] The method of using this utility model is as follows:

[0031] Place the closing gun head 1 above the self-locking nut of the tray that needs closing repair, and press the button on the closing handle 3;

[0032] Then, compressed air drives the pneumatic hydraulic pump 6, and the hydraulic pressure drives the closing gun head 1 to complete the closing repair work in one go. This device is convenient to use, simple to operate, and suitable for various operators.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
