Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing and repairing aircraft hydraulic oil tanks, in particular to a disassembly and decomposition device for aircraft hydraulic oil tanks. Background Art

[0002] The aircraft hydraulic oil tank is a closed cylindrical piston-type structure and an important component of the aircraft hydraulic system. It is used to receive the system return oil, replenish the working fluid when the parts and accessories are working, and pressurize the hydraulic pump suction pipeline to create conditions for the oil pump to work. When the hydraulic oil tank fails in performance or function, the hydraulic oil tank is disassembled and repaired. During the repair process, it is necessary to fix it and disassemble the upper and lower end covers and the internal piston assembly in turn. If it is not fixed properly, there is a risk of the hydraulic oil tank falling off and being damaged during the disassembly process. At the same time, the coaxiality requirements between the piston and the inner wall of the outer cylinder are high. Improper disassembly will damage the surface quality of the outer diameter of the piston or the inner wall of the outer cylinder, reduce the life of the product, and increase the degree of repair of the product. In the actual disassembly and repair process, the requirements for personnel are relatively high, and the disassembly process is also time-consuming and laborious. Therefore, a hydraulic oil tank disassembly and disassembly device with reliable fixing, accurate positioning, and convenient disassembly is required. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a disassembly and decomposition device for an aircraft hydraulic oil tank.

[0005] The height of the supporting feet can be adjusted.

[0006] The rotating bracket comprises an inclination mechanism, a support plate arranged on the inclination mechanism, a plurality of groups of clamps fixedly connected to the support plate, and a locking nut arranged on the clamp.

[0007] The clamp is composed of two semicircular rings, one end of which is connected to the support plate and the other end is locked by a locking nut.

[0008] The beneficial effects of the utility model are as follows: the rotating bracket designed according to the outer structure of the hydraulic oil tank is used for fixing, selecting and tilting the hydraulic oil tank as a whole; the designed feed assembly can ensure the coaxiality of the feed assembly and the rotating bracket, so that the end cover and the piston can be pressed out horizontally along the inner wall of the outer cylinder smoothly and intactly during the disassembly and decomposition process of the hydraulic oil tank; the designed supporting feet and universal wheels are used for the movement of the hydraulic oil tank disassembly and decomposition device and the stability during use.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0018] like Figures 1 to 6 As shown, a disassembly and decomposition device for an aircraft hydraulic oil tank includes a base frame 3, a plurality of groups of support legs 1 welded to the lower end of the base frame 3, a rotating bracket 2 welded to the upper end of the base frame 3 for fixing the hydraulic oil tank, and a feed assembly 4 that cooperates with the rotating bracket 2 for disassembling and decomposing the end cover and piston of the hydraulic oil tank.

[0019] The rotating bracket 2 designed according to the external structure of the hydraulic oil tank is used for fixing, selecting and tilting the entire hydraulic oil tank; the designed feed assembly 4 can ensure the coaxiality of the feed assembly 4 and the rotating bracket 2, so that the end cover and the piston can be pressed out horizontally along the inner wall of the outer cylinder smoothly and intact during the disassembly and disassembly of the hydraulic oil tank; the designed supporting feet 1 and universal wheels are used for the movement of the hydraulic oil tank disassembly and disassembly device and the stability during use.

[0020] The height of the support legs 1 can be adjusted, and four support legs 1 are provided. By rotating the support legs 1, the disassembly and disassembly device can be stably fixed at a desired position, thereby ensuring the stability of the disassembly and disassembly device during use.

[0021] The bottom of the chassis 3 is equipped with four steering wheels to facilitate the movement of the disassembly and decomposition device.

[0022] The rotating bracket 2 includes an inclination mechanism 2-4, a support plate 2-1-5 arranged on the inclination mechanism 2-4, a plurality of groups of clamps 2-1 fixedly connected to the support plate 2-1-5, and a locking nut 2-2 arranged on the clamp 2-1. The disassembly and decomposition device designs the rotating bracket 2 according to the outer structure of the hydraulic oil tank, which is used to fix the hydraulic oil tank to ensure that the hydraulic oil tank itself does not move axially relative to the device.

[0023] The rotating bracket 2 can perform 360-degree horizontal rotation and a certain angle of tilt rotation to ensure that the upper and lower end covers of the hydraulic oil tank are in the best disassembly position, which is convenient for disassembly of the parts on the end covers;

[0024] The clamp 2-1 is composed of two semicircular rings, one end of which is connected to the support plate 2-1-5 and the other end is locked by a locking nut 2-2. One of the semicircular rings is fixedly mounted on the support plate 2-1-5, thereby realizing a rigid connection between the clamp 2-1 and the inclination mechanism 2-4.

[0025] Loosen the locking nut 2-2, open the clamp 2-1, put the oil tank between the clamps 2-1, cover the clamp 2-1, and lock the locking nut 2-2. The pin 2-3 is used to fix the relative rotation between the support plate 2-1-5 on the inclination mechanism 2-4 and the bracket 2-1-1.

[0026] The tilt mechanism 2-4 includes a fixed bracket 2-1-4 welded on the base frame 3, a bracket 2-1-1 hinged to the fixed bracket 2-1-4, a transmission shaft 2-1-2 hinged to the fixed bracket 2-1-4 and the bracket 2-1-1, and a crank 2-1-3 arranged on the fixed bracket 2-1-4. The support plate 2-1-5 cooperates with the bracket 2-1-1 through the pin 2-3. The pin 2-3 is equipped for fixing to prevent circumferential rotation.

[0027] The nut on the crank 2-1-3 is connected to the transmission shaft 2-1-2 by a screw nut mechanism.

[0028] The fixed bracket 2-1-4 is installed in parallel with the bracket 2-1-1, and the two can rotate freely through a rotating bearing, that is, the transmission shaft 2-1-2 is driven to make a linear reciprocating motion relative to the fixed bracket 2-1-4 by rotating the crank 2-1-3, thereby driving the bracket 2-1-1 to rotate at an angle.

[0029] The feed assembly 4 includes a fixed rod 4-2 welded to the base frame 3, a turntable 4-3 installed on the fixed rod 4-2, and a support rod 4-1 sleeved on the fixed rod 4-2 and connected to the turntable 4-3 by a screw nut. When the rotating bracket 2 is in the right extreme position, that is, the horizontal position, its axis is always concentric with the axis of the feed assembly 4, which can effectively solve the problem of stable extrusion of the piston and the end cover along the inner wall of the outer cylinder in the horizontal direction, and avoid abnormal wear between the two due to eccentricity.

[0030] The turntable 4-3 is mounted on the fixed rod 4-2 and can rotate relatively. The support rod 4-1 is sleeved on the fixed rod 4-2 and connected to the turntable 4-3 by a screw nut mechanism, so that the reciprocating linear motion of the support rod 4-1 is achieved by rotating the turntable 4-3, thereby decomposing the oil tank end cover and the piston.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
