Problems solved by technology

[0002] During the maintenance process of the aircraft, it is necessary to disassemble and overhaul the landing gear support of the aircraft. The outer cylinder nut of the aircraft landing gear support is an outer hexagonal nut. The outer cylinder nut is installed inside the outer cylinder of the aircraft landing gear and only protrudes from the support A small part of the plane of the outer cylinder of the seat, the actual detachable position is about 5mm. In the past assembly or disassembly process, the traditional special wrench used has no room for adjustment. Once the wrench is worn out, it cannot be used again. The special wrench only corresponds to one size of nut, which brings great inconvenience to the operation. If an open-end wrench is used for disassembly, since the actual detachable position of the outer tube nut is about 5mm, which is relatively small, the open-end wrench is difficult. When disassembled, even if the decomposed outer cylinder nut is uneven due to the inaccurate clamping position of the open-end wrench, most of the disassembled outer cylinder nuts are severely damaged and cannot be used again, wasting resources

Embodiment

[0037] According to the size of the actual dismantled outer cylinder nut, select the appropriate size of the bushing 7, and install the bushing 7, such as Figure 8 As shown, unscrew the locking sleeve 5, lift the locking screw 4, open the left wrench base 2 and the right wrench base 3 to install the bushing 7, and insert the outer sides of the two bushings 7 into the left wrench base 2 respectively. In the groove one 12 and the groove two 13 of the right wrench base body 3, and tighten and fix with the screw 8, then the locking screw 4 is put down, and the locking sleeve 5 is tightened to form as figure 1 The status shown is ready for use.

[0038] When in use, align the inner hexagonal hole 10 formed by the bushing 7 with the outer cylinder nut, and after putting on the outer cylinder nut, adjust the locking sleeve wrench 6 according to the tightness state, and when there is a certain margin, tighten the locking sleeve wrench 6 , the right end surface of the locking sleeve ...

Abstract

The invention relates to a dismounting and mounting special tool of an outer barrel nut of an undercarriage support.The tool structurally comprises a force application wrench rod group, a left wrench base body, a right wrench base body, a bushing group, a screw group, a locking sleeve, a locking sleeve wrench and a locking screw rod, the bushing group is mounted in the left wrench base body and the right wrench base body and is fixed through the screw group, the force application wrench rod group is fixedly connected with the left wrench base body and the right wrench base body, the left wrench base body and the right wrench base body are locked through the locking screw rod and the locking sleeve, and the bushing group can form an inner hexagonal hole so that the outer barrel nut can be dismounted. When the tool is used, the outer barrel nut is not damaged, the dismounted outer barrel nut can still continue to be used, a bushing has various sizes, can be replaced and can adapt to outer barrel nuts with different sizes, use is convenient, and the structure is compact and simple.
