Description

Technical Field

[0001] The invention belongs to the technical field of aviation equipment, and in particular relates to a disassembly and assembly device for a rocker arm bearing of an aircraft sensor. Background Art

[0002] like Figure 1 As shown in the figure, during the overhaul of a certain type of aircraft, a certain type of sensor rocker arm bearing needs to be disassembled and repaired with the sensor rocker arm. Since the sensor rocker arm is a special-shaped part, and the bearing is small, with an outer diameter of only 20mm, and 3 stop points are evenly distributed along the circumference of its assembly edge during assembly, it is difficult to disassemble and the work efficiency is low. In addition, the bearing is damaged due to improper force during the disassembly process with the rocker arm, causing unnecessary losses. Similar problems also exist during the assembly process. The disassembly and assembly of the bearing in the original sensor rocker arm maintenance process is purely manual. During the disassembly, a steel pipe with a size slightly larger than the inner ring of the bearing is used with a hammer to repeatedly knock it several times to separate it from the rocker arm; during the assembly, a steel pipe with a size slightly smaller than the outer ring of the bearing is used with a hammer to repeatedly knock it several times to match it with the rocker arm bearing mounting hole for installation. Because the disassembly and assembly are both repeatedly knocked by a hammer, the force direction and size are difficult to control, which is easy to cause damage to the bearing and the rocker arm, and the working efficiency is extremely low. Therefore, a dedicated rocker arm sensor bearing disassembly and assembly device is urgently needed. Summary of the invention

[0003] In view of this, the present invention provides an aircraft sensor rocker arm bearing disassembly and assembly device, which can realize the disassembly and assembly of the bearing and the sensor rocker arm, and has two uses in one machine. It improves the disassembly efficiency and avoids the damage that may be caused by the disassembly and assembly of the bearing and the rocker arm.

[0004] The technical solution for implementing the present invention is as follows:

[0005] An aircraft sensor rocker arm bearing disassembly and assembly device, comprising a base, a disassembly transition sleeve, a rotary propulsion mechanism, a top cap and an assembly transition sleeve;

[0006] The disassembly transition sleeve and the assembly transition sleeve are respectively fixed on both sides of the base, the support of the rotating propulsion mechanism is fixed in the middle of the base, and the top cap is fixed at the bottom end of the telescopic output rod of the rotating propulsion mechanism. The rotating propulsion mechanism rotates with its support as the axis, driving the top cap to switch between the upper position of the disassembly transition sleeve and the upper position of the assembly transition sleeve. The telescopic output rod of the rotating propulsion mechanism extends vertically downward, driving the top cap to move vertically downward, squeezing the bearing, thereby realizing the assembly or disassembly of the bearing and the rocker arm.

[0007] Furthermore, the rotary propulsion mechanism comprises a sliding sleeve, a sliding shaft, a screw-in screw, a handle, a spring, a locking steel ball, a rotating beam and a support;

[0008] The support is fixedly connected to the base, and steel ball locking sockets are processed on the left and right sides of the upper end of the support. A rotating shaft of the rotating beam is arranged in the middle of the upper end of the support, and the rotating beam is sleeved on the rotating shaft. A spring mounting hole is processed on the rotating beam, and the spring is pressed in the mounting hole. The locking steel ball is pressed in the steel ball locking socket by the spring to control the locking of the rotating beam on the left and right sides of the support;

[0009] The rotating beam is fixedly connected to the sliding sleeve, the sliding sleeve is processed with a square hole, the sliding shaft is a square column structure, which is sleeved in the square hole, and the sliding shaft is processed with an internal threaded hole, which cooperates with the thread of the screw rod. The upper end of the screw rod is fixedly connected to the handle, and the lower end of the sliding shaft is fixedly connected to the top cap.

[0010] Furthermore, the decomposition transition sleeve is an inner step structure, the step major diameter cooperates with the rocker arm boss, and the step minor diameter is slightly larger than the bearing outer ring, so that the bearing can fall off from the decomposition transition sleeve minor diameter after being subjected to force.

[0011] Furthermore, the assembly transition sleeve has an inner step structure, the major diameter of the step cooperates with the rocker arm boss, and the minor diameter of the step is slightly smaller than the outer ring of the bearing, so that the bearing can be firmly assembled along the installation plane of the assembly transition sleeve after being subjected to force.

[0012] Furthermore, the outer diameter of the top hat is slightly smaller than the outer ring of the bearing.

[0013] Beneficial effects:

[0014] 1. The present invention realizes the disassembly and assembly of the sensor rocker arm and the bearing by driving the counter-hat to cooperate with the disassembly transition sleeve and the assembly transition sleeve through the rotating propulsion mechanism, and replaces the traditional pure manual operation through mechanical transmission control, which improves the operation efficiency and also ensures the integrity of the product during the disassembly and assembly process.

[0015] 2. Both ends of the base of the present invention are equipped with a disassembly transition sleeve and an assembly transition sleeve, so that one machine can be used for two purposes, the operation is convenient, and the working efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figure 2-Figure 6 As shown, the device of the present invention includes 21 parts, including a base, a disassembled transition sleeve, a top cap, a sliding sleeve, a sliding shaft, a locking nut, a dust cap, a pressure cover, a screw-in screw, an assembly screw, a handle, a bearing, a locking top screw, a spring, a locking steel ball, a rotating beam, a pad, a support, and an assembly transition sleeve. The parts are connected and fastened by screws. The base has mounting holes at both ends for installing the disassembled transition sleeve and the assembly transition sleeve. Considering the wear during repeated use, the disassembled transition sleeve and the assembly transition sleeve are designed to be replaceable. The middle of the base is processed with a support mounting hole, and the support is fixedly connected to the middle position of the base by screws. The disassembled transition sleeve is designed as an inner step structure, the step major diameter cooperates with the rocker arm boss, and the step minor diameter is slightly larger than the bearing outer ring, so that it can fall off from the disassembled transition sleeve minor diameter after being subjected to force; the assembly transition sleeve is also designed as an inner step structure, the step major diameter cooperates with the rocker arm boss, and the step minor diameter is slightly smaller than the bearing outer ring, so that it can be firmly assembled along the assembly transition sleeve installation plane after being subjected to force. The sliding sleeve is designed as an inner square structure, and the sliding shaft is designed as an outer square structure. Through the assembly between the top cap, locking nut, bearing, and screw, a propulsion system is formed together. A screw is designed at the lower end of the sliding shaft. The thread here is used to assemble with the top cap. At the same time, the screw passes through the bearing during the disassembly and assembly process, which is convenient for alignment. The top cap is designed to have an outer diameter slightly smaller than the outer ring of the bearing. A thread is provided in the middle to facilitate assembly with the sliding shaft. At the same time, an extrusion plane ring belt is formed in the middle. The ring belt surface contacts the outer ring of the bearing and is a force-bearing surface during extrusion. The propulsion system is fixedly connected to the rotating beam by screws. The rotating beam and the support, bearing, locking cap pad, locking top screw, spring, and locking steel ball form a rotating system: steel ball locking sockets are provided on the left and right ends of the support. When the rotating beam is rotated to the left end disassembly position, the spring presses the locking steel ball into the locking socket to lock the optional system; when the rotating beam is rotated to the right end assembly position, the spring presses the locking steel ball into the locking socket to lock the optional system.

[0025] The top cap cooperates with the disassembly transition sleeve and the sliding shaft, and the vertical downward movement of the sliding shaft in the sliding sleeve is controlled by screwing in the screw rod to disassemble the bearing and the rocker arm. The rotating beam can rotate left and right, and the steel ball is pushed into the locking socket of the support by the locking steel ball and the extrusion of the matching spring to lock the rotating beam. The rotating beam is rotated, and the top cap cooperates with the assembly transition sleeve and the sliding shaft. The vertical downward movement of the sliding shaft in the sliding sleeve is controlled by screwing in the screw rod to assemble the bearing and the rocker arm.

[0026] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
