Description

A tooling for locking aero-engine spherical bearings Technical Field

[0001] This utility model belongs to the field of bearing locking tooling technology, specifically relating to a tooling for locking aero-engine spherical bearings. Background Technology

[0002] Bearings are an essential component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. This is especially true in aircraft engines, which are highly complex and precise thermodynamic machines. As the heart of an aircraft, they not only power flight but also serve as a crucial driving force for the development of aviation. Every significant revolution in human aviation history has been inextricably linked to technological advancements in aircraft engines, and bearings within these engines, particularly spherical plain bearings, play a vital role.

[0003] Spherical plain bearings are a type of spherical sliding bearing. Their sliding contact surfaces consist of an inner spherical surface and an outer spherical surface, allowing them to rotate and oscillate at any angle during operation. They are manufactured using various special processes such as surface phosphating, burring, padding, and spraying. Spherical plain bearings are characterized by high load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning properties, and good lubrication.

[0004] Tooling is required when assembling and locking spherical bearings. However, existing tooling has certain limitations in use because it cannot be adjusted vertically while remaining fixed. Therefore, we propose a tooling for locking spherical bearings in aero-engines. Summary of the Invention

[0005] The purpose of this utility model is to provide a tooling for locking aero-engine spherical bearings, so as to solve the problem that the existing tooling mentioned in the background art has certain limitations in use because it cannot be adjusted vertically under a fixed condition.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling for locking aero-engine spherical bearings, comprising a base plate, mounting holes at each of the four corners of the base plate, two fixing plates fixedly mounted on the upper surface of the base plate, a rotating shaft rotatably mounted on the fixing plates, a support plate fixedly mounted between the two rotating shafts rotatably mounted, a rotating shaft rotatably mounted on the support plate, a handle and a tooling housing fixedly mounted at each end of the rotating shaft rotatably mounted, a bidirectional screw rotatably mounted inside the tooling housing, threaded plates threadedly mounted on the outer surfaces of both threads of the bidirectional screw, one end of the bidirectional screw extending out of the tooling housing and fixedly mounted with a knob, a connecting plate fixedly mounted on the side of the threaded plate, the connecting plate extending out of the tooling housing through a channel opened on the side of the tooling housing and fixedly mounted with a tooling clamping plate, and two tooling limiting plates fixedly mounted on the opposite sides of the two tooling clamping plates.

[0007] By adopting the above scheme, a base plate is set up to work with a fixed plate, a rotating shaft one, a support plate, and a rotating shaft two. The rotating shaft one and rotating shaft two are used to achieve multi-directional rotation and swing adjustment of the tooling housing under the premise of fixing the workpiece, so as to better perform assembly and locking operations. By setting up a tooling clamping plate and a tooling limiting plate to work together, bi-directional clamping and fixing of the workpiece in the vertical direction can be achieved, improving the stability of the fixing effect.

[0008] In a preferred embodiment, a rotating plate is fixedly installed at the end of the rotating shaft, a guide plate is fixedly installed on the side of the fixed plate, an insert plate is inserted into the guide plate, and a plurality of slots are provided on the outer surface of the rotating plate, the insert plate and the slots are used in conjunction.

[0009] Using the above scheme, the guide plate and the insert plate are used in conjunction with the slot. When the insert plate slides out of the slot, the rotating plate is unlocked. At this time, the support plate can be rotated through the rotating shaft. After rotation, the insert plate is inserted into the slot through the guide plate to achieve position locking. The locking structure is simple and easy to operate.

[0010] In a preferred embodiment, the handle has a cavity, and a locking rod is slidably mounted on the handle opposite the cavity. A limiting ring is fixedly mounted on the outer surface of the locking rod. The limiting ring is located inside the cavity, and a spring is fixedly mounted between the limiting ring and the inner wall of the cavity. Several locking grooves are arranged in a circular array on the side of the support plate, and the locking rod and the locking grooves are used in conjunction.

[0011] Using the above scheme, a locking rod is set to work with the locking groove. When the locking rod is disengaged from the locking groove, the handle is unlocked and the spring is deformed. At this time, the handle can drive the rotating shaft two to rotate the tool housing. After rotation, the spring force is used to drive the locking rod to quickly insert into the locking groove to achieve convenient locking. At the same time, the setting of the limit ring can play a limiting role to prevent the locking rod from slipping off the handle.

[0012] In a preferred embodiment, an annular track is fixedly installed on the side of the support plate, and a plurality of arc-shaped sliders are fixedly installed on the side of the tooling housing, the arc-shaped sliders being slidably mounted on the outer surface of the annular track.

[0013] By adopting the above scheme, and using a ring track bar in conjunction with an arc-shaped slider, the rotational stability of the tooling housing can be guaranteed. Furthermore, the cross-section of the ring track bar can be set to a trapezoidal shape, which ensures that the arc-shaped slider and the ring track bar will not separate, further improving the rotational stability of the tooling housing.

[0014] In a preferred embodiment, a plurality of support rods are fixedly installed on the inner wall of the tooling housing, and the threaded plate is slidably installed on the outer surface of the plurality of support rods.

[0015] By adopting the above scheme, the movement of the threaded plate can be guided by the support rod, thus preventing the threaded plate from shaking during movement.

[0016] In a preferred embodiment, a locking threaded hole is provided at the middle position of one of the tooling limit plates on the tooling clamp, and a locking screw is installed on the inner wall of the locking threaded hole.

[0017] By using the above solution, the tooling limit plate and locking screws can be used to clamp and lock the workpiece fixed between two toolings in the vertical direction, further improving the fixing and clamping effect.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The tooling for locking aero-engine spherical bearings uses a base plate in conjunction with a fixed plate, a rotating shaft one, a support plate, and a rotating shaft two. The rotating shaft one and rotating shaft two enable the tooling housing to rotate and swing in multiple directions while fixing the workpiece, thus enabling better assembly and locking operations.

[0020] This tooling for locking aero-engine spherical bearings uses a tooling clamp and a tooling limit plate in combination to achieve bidirectional clamping and fixing of the workpiece in the vertical direction, thereby improving the stability of the fixing effect. Attached Figure Description

[0027] Please refer to Figures 1-5. This utility model provides a tooling for locking aero-engine spherical bearings, including a base plate 1. Mounting holes are provided at the four corners of the base plate 1. Two fixing plates 2 are fixedly installed on the upper surface of the base plate 1. A rotating shaft 3 is rotatably installed on the fixing plate 2. A support plate 4 is fixedly installed between the two rotating shafts 3. A rotating shaft 5 is rotatably installed on the support plate 4. A handle 6 and a tooling housing 7 are fixedly installed at both ends of the rotating shaft 5, respectively. A bidirectional screw 8 is rotatably installed inside the tooling housing 7. Threaded plates 9 are threaded on the outer surfaces of the two threaded sections of the bidirectional screw 8. One end of the bidirectional screw 8 extends out of the tooling housing 7 and is fixedly installed with a knob. A connecting plate 10 is fixedly installed on the side of the threaded plate 9. The connecting plate 10 extends out of the tooling housing 7 through a channel opened on the side of the tooling housing 7 and is fixedly installed with a tooling clamping plate 11. Two tooling limiting plates 12 are fixedly installed on the opposite sides of the two tooling clamping plates 11.

[0028] By using the base plate 1 in conjunction with the fixing plate 2, the first rotating shaft 3, the support plate 4, and the second rotating shaft 5, the tooling housing 7 can be adjusted in multiple directions while fixing the workpiece, thereby enabling better assembly and locking operations. By using the tooling clamping plate 11 and the tooling limiting plate 12 in conjunction, the workpiece can be clamped and fixed in both directions in the vertical direction, improving the stability of the fixing effect.

[0029] A rotating plate 13 is fixedly installed at the end of the rotating shaft 3, and a guide plate 14 is fixedly installed on the side of the fixed plate 2. An insert plate 15 is inserted into the guide plate 14. Several slots are opened on the outer surface of the rotating plate 13. The insert plate 15 is used in conjunction with the slots. When the insert plate 15 slides out of the slot, the rotating plate 13 is unlocked. At this time, the support plate 4 can be rotated through the rotating shaft 3. After rotation, the insert plate 15 is inserted into the slot through the guide plate 14 to achieve position locking. The locking structure is simple and easy to operate.

[0030] The handle 6 has a cavity, and a locking rod 16 is slidably installed on the handle 6 opposite the cavity. A limiting ring 17 is fixedly installed on the outer surface of the locking rod 16. The limiting ring 17 is located inside the cavity, and a spring 18 is fixedly installed between the limiting ring 17 and the inner wall of the cavity. The side of the support plate 4 is arranged in a ring array with several locking slots. The locking rod 16 and the locking slots are used together. When the locking rod 16 is disengaged from the locking slot, the handle 6 is unlocked and the spring 18 is deformed. At this time, the handle 6 can drive the rotating shaft 2 5 to rotate the tooling housing 7. After rotation, the spring force of the spring 18 drives the locking rod 16 to quickly insert into the locking slot to achieve convenient locking. At the same time, the setting of the limiting ring 17 can play a limiting role to prevent the locking rod 16 from disengaging from the handle 6 when sliding.

[0031] A ring track 20 is fixedly installed on the side of the support plate 4, and several arc-shaped sliders 19 are fixedly installed on the side of the tooling housing 7. The arc-shaped sliders 19 are slidably installed on the outer surface of the ring track 20. By setting the ring track 20 to work with the arc-shaped sliders 19, the rotational stability of the tooling housing 7 can be guaranteed. Furthermore, the cross-section of the ring track 20 can be set to a trapezoidal shape, which can ensure that the arc-shaped sliders 19 and the ring track 20 will not separate, further improving the rotational stability of the tooling housing 7.

[0032] Several support rods 21 are fixedly installed on the inner wall of the tool housing 7. The threaded plate 9 is slidably installed on the outer surface of the several support rods 21. The support rods 21 can guide the movement of the threaded plate 9 and prevent the threaded plate 9 from shaking when it moves.

[0033] A locking threaded hole is provided at the middle position of one of the tooling limit plates 12 on the tooling clamping plate 11, and a locking screw 22 is installed on the inner wall of the locking threaded hole. By using the tooling limit plate 12 in conjunction with the locking screw 22, the workpiece fixed between the two toolings can be pressed and locked in the vertical direction, further improving the fixing and clamping effect.

[0034] In use, first fix the base plate 1 with bolts. After fixing, place the joint bearing to be assembled and locked on the side of the tooling housing 7 and between the two tooling clamping plates 11. Then, turn the knob to drive the bidirectional screw 8 to rotate, which in turn drives the two threaded plates 9 to drive the two tooling clamping plates 11 closer together through the connecting plate 10, thereby fixing and clamping the workpiece. Then, screw in the locking screw 22 and use the tooling limiting plate 12 to fix and clamp the workpiece perpendicular to the fixing direction of the tooling clamping plates 11. After fixing, assemble. When locking requires adjustment and rotation, pull out the insert plate 15. At this time, the rotating plate 13 is unlocked, and the support plate 4 can be rotated and swung through the rotating shaft 3. After adjusting to the appropriate position, insert the insert plate 15 to lock. Then pull the locking rod 16 to drive the locking rod 16 out of the lock groove. At this time, the spring 18 deforms and the rotating handle 6 is unlocked. The tooling housing 7 can be rotated and swung in another direction through the rotating shaft 5. After adjusting to the appropriate position, release the locking rod 16. Use the elastic force of the spring 18 to drive the locking rod 16 back to the lock groove to lock.
