Description

Technical Field

[0001] This utility model relates to the field of aircraft maintenance technology, specifically a tooling for removing the bearing at the end of an aircraft governor shaft. Background Technology

[0002] During aircraft maintenance, removing the governor shaft end bearing is a complex and delicate task. Traditional removal methods often require a lot of time and manpower, and improper operation can easily damage the bearing or other components of the governor. Therefore, a tooling that can efficiently and safely remove the aircraft governor shaft end bearing is needed.

[0003] Referring to a small bearing removal tool (CN214560537U), the tool includes a placement base. The placement base comprises an integrally connected base plate, a first side plate, a second side plate, a third side plate, and a fourth side plate. Connecting plates are provided along the top edges of the first, second, third, and fourth side plates. The first and third side plates correspond to each other, as do the second and fourth side plates. Openings are provided at the first side plate and its connecting plate. Placement portions are spaced apart on the inner surface of the first side plate, within which mounting plates are movably placed. The mounting plate is threaded with a screw, and the third side plate and its connecting plate also have openings. The inner side of the third side plate is provided with spaced placement parts, and a clamping plate is movably placed in the placement parts. The clamping plate has a clamping groove with an opening facing downwards. A pressure plate is provided on the connecting plate. This is used to solve the problem that the existing method of hammering can easily damage the bearings. As can be seen from the above, although this dismantling tool can be used well, it is usually not convenient to automatically collect and process the dismantled bearings, which makes the bearings easy to scatter and be lost, often troubling users. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling for removing bearings from the shaft end of an aircraft speed controller, in order to solve the problem that although the removal tooling mentioned in the background art can be well applied, it is usually not convenient to automatically collect the disassembled bearings, which makes the bearings easy to be scattered and lost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for removing the bearing at the end of an aircraft speed controller shaft, comprising a base plate, two support frames on one side of the top of the base plate, a first lead screw transmission mechanism at the top of the support frames, a first motor mounted on the outer wall of one side of the first lead screw transmission mechanism, a first linkage plate mounted on one side of the surface of the first lead screw transmission mechanism, a second lead screw transmission mechanism on the surface of the first linkage plate, a second motor mounted at the top of the second lead screw transmission mechanism, a second linkage plate mounted at the upper end of the surface of the second lead screw transmission mechanism, a positioning seat on the surface of the second linkage plate, a third motor mounted at the top of the positioning seat, and a gripper at the bottom end of the third motor penetrating the positioning seat.

[0006] Preferably, the bottom plate on one side of the support frame is provided with two base plates, and a collection frame is provided on one side of the two base plates. The collection frame is provided to collect the disassembled bearings.

[0007] Preferably, the substrate has limiting rails on both sides of the top end, a support plate on the top of the substrate, and a rail seat slidably connected to the top of the limiting rail. The top end of the rail seat is connected to the bottom end of the support plate. The setting of the rail seat and the limiting rail can limit the movement range of the support plate.

[0008] Preferably, an electric push rod is mounted on the top of the base plate on one side of the limiting rail via a bracket. One end of the electric push rod is connected to the outer wall of the support plate. The electric push rod is used to drive the support plate to move horizontally.

[0009] Preferably, the top of the bearing plate is provided with a base, one side of the top of the base is provided with a first clamping plate, and the other side of the top of the base is provided with a nut seat. The nut seat is provided to facilitate the placement of the screw component.

[0010] Preferably, a screw is installed on the internal thread of the nut seat, and both ends of the screw extend to the outside of the nut seat. A second clamp is rotatably installed on the end of the screw near the first clamp, and the bottom end of the second clamp contacts the top end of the base. The second clamp is provided to cooperate with the first clamp to clamp and fix the speed controller.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the tooling for removing the bearing at the end of the speed governor shaft not only reduces the phenomenon of bearings being scattered and lost after removal, but also reduces the phenomenon of displacement during the removal of the bearing at the end of the speed governor shaft, so as to ensure the removal effect of the bearing at the end of the speed governor shaft and ensure the removal efficiency of the bearing at the end of the speed governor shaft when using the tooling.

[0012] (1) The second screw transmission mechanism is driven by the second motor to operate, so that the second screw transmission mechanism drives the gripper to lift and lower via the second linkage plate. Then, the first screw transmission mechanism is driven by the first motor to operate, so that the first screw transmission mechanism drives the gripper to move horizontally via the first linkage plate. The third motor can drive the gripper to rotate slowly, so as to automatically clamp and remove the bearing at the end of the speed regulator shaft, and transfer the removed bearing to the inside of the collection frame for collection, thereby reducing the phenomenon of the removed bearing being scattered and lost.

[0013] (2) By placing the speed controller on the top of the base between the first clamping plate and the second clamping plate, and then turning the screw inside the nut seat to rotate and slide, the screw drives the second clamping plate to translate and fit against the outer wall of the speed controller. The second clamping plate, together with the first clamping plate, clamps and fixes the speed controller to the top of the base, thereby reducing the displacement phenomenon during the removal of the speed controller shaft end bearing and ensuring the removal effect of the speed controller shaft end bearing.

[0014] (3) The bearing plate is driven to move back and forth by the electric push rod, so that the bearing plate drives the rail seat to slide on the top of the limit rail, so that the bearing plate drives the speed controller clamped and fixed above it to move back and forth. Since there are two sets of bearing plate and related components, the two speed controllers are moved to the bottom of the gripper in sequence for dismantling. This achieves the purpose of dismantling the speed controller shaft end bearing in sequence in two stations, thus ensuring the dismantling efficiency of the speed controller shaft end bearing when the dismantling tool is used.

[0021] Please see Figure 1-4 An embodiment of this utility model is provided: a tooling for removing the bearing at the end of an aircraft speed controller shaft, including a base plate 1, two support frames 2 on one side of the top of the base plate 1, two base plates 13 on the top of the base plate 1 on one side of the support frames 2, and a collection frame 12 on one side of the two base plates 13.

[0022] When in use, the collection box 12 is set up to collect the dismantled bearings;

[0023] Limiting rails 21 are provided on both sides of the top of the substrate 13, and a support plate 14 is provided on the top of the substrate 13. A rail seat 22 is slidably connected to the top of the limiting rail 21, and the top of the rail seat 22 is connected to the bottom of the support plate 14.

[0024] In use, the movement range of the bearing plate 14 is limited by the setting of the rail base 22 and the limiting rail 21;

[0025] An electric push rod 20 is mounted on the top of the base plate 13 on one side of the limiting rail 21 via a bracket. One end of the electric push rod 20 is connected to the outer wall of the bearing plate 14.

[0026] In use, the electric push rod 20 is set to drive the support plate 14 to move horizontally;

[0027] The top of the bearing plate 14 is provided with a base 15, one side of the top of the base 15 is provided with a first clamping plate 16, and the other side of the top of the base 15 is provided with a nut seat 18.

[0028] In use, the nut seat 18 is provided to accommodate the screw 19.

[0029] A screw rod 19 is installed on the internal thread of the nut seat 18. Both ends of the screw rod 19 extend to the outside of the nut seat 18. A second clamping plate 17 is rotatably installed on the end of the screw rod 19 near the first clamping plate 16. The bottom end of the second clamping plate 17 contacts the top end of the base 15.

[0030] In use, the second clamping plate 17 is set to cooperate with the first clamping plate 16 to clamp and fix the speed controller.

[0031] The top of the support frame 2 is provided with a first lead screw transmission mechanism 3. A first motor 4 is installed on the outer wall of one side of the first lead screw transmission mechanism 3. A first linkage plate 5 is installed on one side of the surface of the first lead screw transmission mechanism 3. A second lead screw transmission mechanism 6 is provided on the surface of the first linkage plate 5. A second motor 7 is installed at the top of the second lead screw transmission mechanism 6. A second linkage plate 8 is installed at the upper end of the surface of the second lead screw transmission mechanism 6. A positioning seat 9 is provided on the surface of the second linkage plate 8. A third motor 10 is installed at the top of the positioning seat 9. The bottom end of the third motor 10 passes through the positioning seat 9 and is provided with a gripper 11.

[0032] In this embodiment, the speed controller is first placed on the top of the base 15 between the first clamping plate 16 and the second clamping plate 17. Then, the screw 19 is rotated and slid inside the nut seat 18, causing the screw 19 to drive the second clamping plate 17 to translate and adhere to the outer wall of the speed controller. The second clamping plate 17, in conjunction with the first clamping plate 16, clamps and fixes the speed controller to the top of the base 15, reducing displacement during the removal of the speed controller shaft bearing. Then, the electric push rod 20 drives the bearing plate 14 to move back and forth, causing the bearing plate 14 to slide the rail seat 22 on top of the limiting rail 21. This allows the bearing plate 14 to move the speed controller clamped and fixed above it back and forth. Due to the arrangement of the bearing plate 14 and other related components... There are two sets of equipment to sequentially move the two speed controllers to the underside of the gripper 11 for dismantling. This allows for the sequential dismantling of the speed controller shaft bearings in a dual-station configuration. Finally, the second motor 7 drives the second lead screw transmission mechanism 6, which in turn drives the gripper 11 to move up and down via the second linkage plate 8. The first motor 4 then drives the first lead screw transmission mechanism 3, which in turn drives the gripper 11 to move horizontally via the first linkage plate 5. The third motor 10 drives the gripper 11 to rotate slowly, thus automating the clamping and dismantling of the speed controller shaft bearing. The dismantled bearing is then transferred to the collection frame 12 for collection, completing the dismantling process.
