Definitions
- the invention relates to a portable tool for machining the lower part of an aircraft landing gear box.
- the undercarriages generally comprise a leg comprising a box inside which a rod is mounted to slide.
- the rod has a lower portion carrying the wheels of the undercarriage.
- the box has in its lower part a bearing to guide the sliding of the rod in the box.
- This bearing is engaged in an end bore of the box being held by pins.
- the invention aims to provide a device for intervention on the subwoofer 1 while the latter is still in place on one aircraft.
- a portable machining tool for a lower part of an aircraft landing gear box, comprising a positioning collar on the lower part of the caisson, at least one airfoil member. indexing for angularly indexing and immobilizing the collar on the casing, a support removably attached to the collar and equipped with a motorized machining spindle which carries a movably mounted tool on the support in a convergent direction with the box for machining a hole extending opposite the tool, the collar being arranged to be able to receive the support in several angular positions in each of which the tool extends opposite one of the orifices to be machined .
- the tooling thus makes it possible to limit the dismantling operations of the undercarriage and to intervene directly under the aircraft. Indeed, to bore the orifices that have suffered corrosion, it suffices to depressurize the damper 1 landing gear, to empty it of oil if necessary, then to remove the rod of the box to be able to remove the lower bearing of this- ci, and the rotating sleeve which is mounted around the lower part of the box to receive one of the branches of the steering compass.
- the orifices to be repaired are then visible and accessible, and simply present the collar of the tool to put it in place on the lower part of the box. The collar is then indexed, and the support is reported on the collar so that the boring tool then extends opposite one of the orifices to be bored. It is then sufficient to activate the machining spindle and to proceed to the machining of the orifice.
- the collar comprises a series of guides extending opposite each orifice to be machined either to receive an indexing member of the collar on the box, or to serve as a guide for the tool. when machining the orifice opposite.
- Figure 1 is a perspective view of a box on which a tool according to the invention has been adapted
- Figure 2 is a longitudinal sectional view of the box of Figure 1, provided with the tool according to one invention
- Figure 3 is a top view of the tool according to the invention.
- the tool of the invention is here used to bore holes in a subwoofer 1.
- This box can still be mounted on the aircraft, the sliding rod has been disassembled.
- the box may still have been detached from the aircraft to be repaired in the hangar in which the aircraft was stored, or a nearby workshop.
- the casing 1 comprises a generally cylindrical lower part of Z axis which has a cylindrical outer surface 2 normally receiving a rotating sleeve forming a portion of the orientation member for orienting the wheels of the landing gear.
- This sleeve has been disassembled here, as well as the flanges receiving the orientation actuators which act on this sleeve to rotate it.
- the casing 1 comprises in the lower part a cylindrical inner surface 3 normally receiving a sliding bearing of a rod mounted to slide telescopically into the casing.
- this bearing has been disassembled.
- Orifices 4 are drilled in the wall 5 of the lower part of the box 1 according to here radial directions. These orifices 4 are intended to receive indexing pins of the bearing or fasteners thereof. These holes 4 are likely to corrode, and it is important to be able to bore them to eliminate surface corrosion.
- a portable tooling machining 100 comprising a collar 10 adapted to fit around the lower part of the box 1.
- the collar 10 comprises indexing fingers 12 (for example expandable pins) intended to penetrate into one of the orifices 4 of the box to angularly index the collar 10 about a longitudinal axis thereof and to immobilize the tooling on the casing 1.
- the indexing fingers 12 are three in number, and are introduced into guides 19 of the collar 10 which extend opposite the orifices of the casing to be bored. One of the guides 19 is left free.
- a support 13 is removably attached to the collar 10.
- the support 13 comprises a carriage 14 movable in a direction X converging towards the box, coinciding with an axis of the guide 19 left free.
- the carriage 14 carries a boring spindle 15 provided with a motor 16 for rotating a reamer 17 terminated by a guide end 18.
- the boring spindle 15 is mounted movably on the support 12 in the direction X.
- reamer 17 extends opposite one of the orifices of the box. It suffices to turn on the motor of the boring spindle 15 and to move the carriage 14 by means of the crank 20 in order to bore the orifice 4 opposite, the boring spindle 15 moving in a block with the carriage 14, the reamer being guided by the guide 19.
- the support 13 of the collar 10 is disassembled.
- An indexing finger 12 is placed in the guide 19 and the orifice is bored, and a indexing finger 12 of one of the other guides 19.
- the support 13 is reported on the collar 10 so that the reamer 17 extends opposite the guide 19 thus released.
- handles 21 extending on either side of the support 13, as well as handles 22 fixed on the bottom of the collar 10.
- Each guide 19 present on the collar 10 is provided with two cylindrical positioning studs 23 located on either side of the guide 19 and extending in a plane perpendicular to the axis of the indexing finger 12 and to the axis Z of the box 1.
- Each pin 23 cooperates with the curved portion of a hook 24 secured to the support 13 so that the support is held in position relative to the collar is formed by these two hooks 24.
- each hook 24 is integrated in a rectangular plate 25 reported by bolting on the lateral faces of the support 13.
- the removal of the support 13 is done by translating it in a direction parallel to the Z axis of the box 1 to clear the hooks 24 of the nipples 23.
- the support can then be attached to a new orifice to be machined.
- a collar is thus obtained equipped with the fixing means of the machining support 13 in several distinct locations, each location facing one of the orifices to be machined.
- the invention is not limited to reboring operations. It may for example be adapted on the spindle a drill to enlarge the orifices.
