Description

Technical Field

[0001] The invention belongs to the technical field of aviation maintenance equipment, in particular to a device for facilitating the recovery and cleaning of bolts. Background Art

[0002] At present, aircraft tires adopt a tubeless, double-tread structure, that is, they are not solid tires. Aircraft tires are subject to great impact during landing. If they are still used after being worn to a certain extent, potential risks will arise. The commonly used aircraft tire removal device, during the removal process, first separates the tire from the wheel hub, and then uses an operating gun to remove the bolts on the wheel hub, and then removes the entire tire through a collection box for the bolts. However, since the bolts will produce a large amount of oil or dust on their surfaces after long-term use, long-term cleaning may easily lead to unstable installation or jamming between the bare double and the screw holes, making it inconvenient to disassemble and assemble.

[0003] Most of the existing devices for recycling and cleaning bolts pour the disassembled bolts into an ultrasonic cleaning machine and clean the bolts uniformly through ultrasonic vibration. However, since the bolts on the aircraft tires are easily exposed to oily substances such as engine oil and are not easy to dissolve, the oil stains will float on the surface of the water during cleaning to form an oil film. Long-term use will cause serious water pollution for cleaning the bolts. If the water is not changed in time, it will easily affect the subsequent cleaning work, resulting in incomplete cleaning of the bolts. At the same time, continuous water changes are also likely to cause low cleaning efficiency.

[0004] Therefore, a device for recovering and cleaning bolts is proposed to solve the problems raised in the background technology. Summary of the invention

[0012] Preferably, the turntable is in the shape of a disk, and a plurality of through grooves and arc grooves distributed in a circular array are provided on the surface of the turntable. The through grooves and arc grooves are arranged at intervals at the edge of the turntable, and the through grooves are U-shaped strip grooves, which are clamped with the driving rod.

[0013] Preferably, the protrusion is crescent-shaped, the protruding end of the protrusion is matched and engaged with the arc groove and slides along the arc groove, and the driving rod is located on the driving disk near the concave side of the protrusion.

[0014] Preferably, a clamping assembly for fixing the bottom oil-absorbing paper is provided on the mounting block.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention facilitates the adsorption of oil stains on the surface of the water flow inside the ultrasonic cleaning machine by arranging the coordination of structures such as the mounting ring, the mounting block, the electric cylinder and the oil absorbing paper, and then utilizes the degreasing mechanism to absorb the oil film on the water surface, firstly the oil absorbing paper is mounted on the bottom of the mounting block, and the electric cylinder drives the fixing plate to rise and fall, and when cleaning is needed, the fixing plate is moved downward, driving the top connecting plate and the supporting plate to move downward synchronously, and then driving the two mounting rings and the mounting block to move downward, so that the bottom oil absorbing paper contacts the water surface, and the oil stains on the water surface are adsorbed, and in order to achieve uniform adsorption during the adsorption process, the electric push rod can be used to push the fixing block to drive the fixing block to slide on the surface of the mounting plate, and then drive the top oil absorbing paper to slide and adsorb on the water surface synchronously, thereby achieving more comprehensive adsorption of surface oil stains, and solving the problem that the existing cleaning device is not convenient for rapid treatment of oil stains on the water surface, and easily leads to serious pollution of the cleaning water source and incomplete cleaning of the bolts.

[0017] The present invention facilitates the adsorption of oil stains by multiple oil-absorbing papers at the same time by arranging the coordination of structures such as a turntable, a driving disk, a driving rod, and a motor, thereby reducing the replacement frequency of the oil-absorbing papers and improving work efficiency. The driving assembly is used to drive the entire mounting ring and the mounting block to rotate and adjust, so as to achieve the adsorption effect of multiple oil-absorbing papers on one side. The motor is used to drive the driving disk to rotate, so that the driving rod and the protrusion on the driving disk rotate synchronously. During the rotation, the driving rod makes a circular motion, and the protrusion slides in a circular motion with the arc groove on the turntable, thereby driving the driving rod to intermittently slide into the inside of the through groove, so that the turntable rotates accordingly. The rotation of the turntable drives the mounting ring to rotate accordingly, so that the mounting block and the oil-absorbing papers rotate synchronously and intermittently, so as to achieve the intermittent adsorption of multiple oil-absorbing papers, which not only ensures the adsorption degree but also improves the adsorption efficiency, and solves the problem that the single oil-absorbing paper needs to be constantly replaced for adsorption.

By manually pressing the top of the clamping block to squeeze the spring, the upper half of the spring is in a compressed state and the lower half is in an extended state, which drives the bottom of the clamping block to tilt up and away from the oil absorbing paper, making it easy to remove the oil absorbing paper for replacement. After the new oil absorbing paper is placed, the clamping block is released, the spring is deformed and reset, driving the clamping block to reset, so that the bottom of the clamping block is close to the oil absorbing paper to clamp the oil absorbing paper.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 6As shown, the present invention provides a device for recovering and cleaning bolts, comprising a cleaning machine body 1, a mounting plate 11 is fixedly connected to the top of the cleaning machine body 1, a placement basket 2 for placing bolts is clamped on the cleaning machine body 1, and a degreasing mechanism 3 is arranged on the top of the mounting plate 11; the degreasing mechanism 3 comprises two mounting rings 31, the two mounting rings 31 are distributed on two symmetrical sides of the top of the cleaning machine body 1, the two mounting rings 31 are fixedly connected to a fixed clamping block 311 on one side close to each other, a plurality of mounting blocks 32 distributed in a ring array are fixedly connected to the two fixed clamping blocks 311 on one side close to each other, the bottoms of the plurality of mounting blocks 32 are installed with oil absorbing paper 4 for absorbing the oil film on the surface of the water surface inside the cleaning machine body 1, and a fixing plate is arranged on one side of the two mounting rings 31 away from each other. 33, two groups of electric cylinders 34 are fixedly connected to the bottom of the two fixed plates 33, and fixed blocks 35 are fixedly connected to the bottom of the two groups of electric cylinders 34. The two fixed blocks 35 are symmetrically arranged on the symmetrical sides of the mounting plate 11 and are slidably connected to the top of the mounting plate 11. One side of the two fixed blocks 35 is fixedly connected to an electric push rod 5, and one end of the electric push rod 5 away from the fixed block 35 is fixedly connected to the mounting plate 11. The tops of the two fixed plates 33 are fixedly connected to a connecting plate 331 and a supporting plate 332. The connecting plate 331 and the supporting plate 332 are perpendicular to the fixing plate 33 and are arranged in sequence on the top of the fixing plate 33. A driving assembly 36 is provided on one side of one of the connecting plates 331 close to the mounting ring 31, and the driving assembly 36 is used to drive the mounting ring 31 and the mounting block 32 to rotate.

[0023] The above scheme is adopted: the bolts collected from the aircraft wheel hub are uniformly poured into the placement basket 2, the placement basket 2 is clamped on the top of the cleaning machine body 1, and the cleaning machine body 1 is started to vibrate and clean it by ultrasonic wave. In the cleaning process, in order to avoid the problem that a lot of oil generated during cleaning floats on the water surface, resulting in incomplete cleaning, the oil film on the water surface can be adsorbed by using the degreasing mechanism 3. The oil-absorbing paper 4 is first installed at the bottom of the mounting block 32, and the fixing plate 33 is driven to rise and fall by the electric cylinder 34. When cleaning is required, the fixing plate 33 is moved downward, driving the top connecting plate 331 and the support plate 332 to move downward synchronously, and then driving the two mounting rings 31 and the mounting block 32 to move downward, so that the bottom oil-absorbing paper 4 contacts the water surface, and the oil on the water surface is adsorbed. In order to achieve uniform adsorption during the adsorption process, the electric push rod 5 can be used to push the fixing block 35 to drive the fixing block 35 to slide on the surface of the mounting plate 11, and then drive the top oil-absorbing paper 4 to slide and adsorb on the water surface synchronously, thereby achieving more comprehensive adsorption of surface oil.

[0024] like Figure 3As shown, the driving assembly 36 includes two rotating disks 361, and a driving disk 362 for driving the rotating disk 361 to rotate is disposed on one side of the two rotating disks 361. A protrusion 363 is fixedly connected to one side of the two driving disks 362 close to the mounting ring 31, and a driving rod 364 is fixedly connected to the two driving disks 362. A motor 365 is fixedly disposed at the central axis of one of the driving disks 362, and the motor 365 is fixedly connected to one of the connecting plates 331. The central axis of the driving disk 362 is rotatably connected to the connecting plate 331. A rotating shaft 3611 is fixedly connected to the center of the rotating disk 361, and the rotating shaft 3611 is fixed to the center of the mounting ring 31. The rotating shaft 3611 passes through the supporting plate 332 and is rotatably connected with the supporting plate 332. The turntable 361 is in the shape of a disk. A plurality of through grooves 3612 and arc grooves 3613 are arranged in a circular array on the surface of the turntable 361. The through grooves 3612 and the arc grooves 3613 are arranged at intervals at the edge of the turntable 361. The through grooves 3612 are U-shaped strip grooves. The through grooves 3612 are engaged with the driving rod 364. The protrusion 363 is in the shape of a crescent. The protruding end of the protrusion 363 is matched with the arc groove 3613 and is engaged and slides along the arc groove 3613. The driving rod 364 is located on the concave side of the driving disk 362 close to the protrusion 363.

[0025] The above scheme is adopted: by using the driving assembly 36 to drive the entire mounting ring 31 and the mounting block 32 to rotate and adjust, the effect of adsorption of multiple oil-absorbing papers 4 on one side is achieved, and the problem of continuous replacement of a single oil-absorbing paper 4 for adsorption is avoided. The motor 365 is used to drive the driving disk 362 on one side to rotate, so that the driving rod 364 and the protrusion 363 on the driving disk 362 on one side rotate synchronously. During the rotation, the driving rod 364 makes a circular motion, and the protrusion 363 engages and slides with the arc groove 3613 on the rotating disk 361 to make a circular motion, thereby driving the driving rod 364 to intermittently slide into the inside of the through groove 3612, so that the rotating disk 361 rotates accordingly. The rotation of the rotating disk 361 drives the mounting ring 31 to rotate accordingly, thereby causing the mounting block 32 and the oil-absorbing paper 4 to rotate synchronously and intermittently, and at the same time drives the rotating disk 361 and the driving disk 362 on the other side to rotate. The two sides rotate at the same time, which is more stable, and multiple oil-absorbing papers 4 are adsorbed at intervals, which not only ensures the adsorption degree but also improves the adsorption efficiency.

[0026] like Figure 4 As shown, a clamping assembly 37 for fixing the bottom oil-absorbing paper 4 is provided on the mounting block 32, and the clamping assembly 37 includes two clamping blocks 371, and the two clamping blocks 371 are symmetrically arranged on both sides of the mounting block 32, and the clamping blocks 371 are L-shaped, and a spring 372 is fixedly connected to one longitudinal side of the clamping block 371, and one end of the spring 372 away from the clamping block 371 is fixedly connected to the side of the mounting block 32.

[0027] The above scheme is adopted: the oil-absorbing paper 4 at the bottom of the mounting block 32 is quickly replaced by utilizing the clamping assembly 37. When use is completed, the top of the clamping block 371 is manually pressed to squeeze the spring 372. The upper half of the spring 372 is in a compressed state, and the lower half is in an extended state, driving the bottom of the clamping block 371 to tilt up and away from the oil-absorbing paper 4, making it easy to remove the oil-absorbing paper 4 for replacement. After the new oil-absorbing paper 4 is placed, the clamping block 371 is released, and the spring 372 is deformed and reset, driving the clamping block 371 to reset, so that the bottom of the clamping block 371 is close to the oil-absorbing paper 4 to clamp the oil-absorbing paper 4.

[0028] The working principle and use process of the present invention are as follows: when using the device, the bolts collected from the wheel hub of the aircraft are poured into the placement basket 2, and the placement basket 2 is clamped on the top of the cleaning machine body 1. The cleaning machine body 1 is started and ultrasonic vibration cleaning is performed. During the cleaning process, in order to avoid the problem that a lot of oil generated during cleaning floats on the water surface, resulting in incomplete cleaning, the oil film on the water surface can be adsorbed by using the oil removal mechanism 3. The oil-absorbing paper 4 is first installed at the bottom of the mounting block 32, and the fixing plate 33 is driven to rise and fall by the electric cylinder 34. When cleaning is required, the fixing plate 33 is moved downward, driving the top connecting plate 331 and the supporting plate 332 to move downward synchronously, thereby driving The two mounting rings 31 and the mounting block 32 move downward, so that the bottom oil-absorbing paper 4 contacts the water surface, and absorbs the oil on the water surface. In order to achieve uniform absorption during the absorption process, the electric push rod 5 can be used to push the fixed block 35 to drive the fixed block 35 to slide on the surface of the mounting plate 11, thereby driving the top oil-absorbing paper 4 to slide and absorb on the water surface synchronously, thereby achieving more comprehensive absorption of surface oil. In order to avoid the problem of constantly replacing a single oil-absorbing paper 4 in a short time, the driving assembly 36 is used to drive the entire mounting ring 31 and the mounting block 32 to rotate and adjust, so as to drive the replacement of multiple oil-absorbing papers 4 for absorption, thereby enhancing the oil absorption effect. At the same time, the absorption of multiple oil-absorbing papers 4 can share the absorption of a single oil-absorbing paper 4. The saturation is attached, so that multiple oil-absorbing papers 4 will not be fully absorbed in a short time, and the replacement time of the oil-absorbing papers 4 can be extended. After a day's work, they can be replaced uniformly, which is quick and convenient, improves the work effect, and avoids the problem of frequent replacement of a single oil-absorbing paper 4. The motor 365 drives the driving disk 362 to rotate, so that the driving rod 364 and the protrusion 363 on one side of the driving disk 362 rotate synchronously. During the rotation, the driving rod 364 makes a circular motion, and the protrusion 363 engages with the arc groove 3613 on the rotating disk 361 to slide in a circular motion, thereby driving the driving rod 364 to intermittently slide into the inside of the through groove 3612, so that the rotating disk 361 rotates accordingly, and the rotation of the rotating disk 361 drives the mounting ring 3 1 rotates accordingly, thereby making the mounting block 32 and the oil-absorbing paper 4 rotate synchronously and intermittently, and at the same time driving the turntable 361 and the driving disk 362 on the other side to rotate. Both sides rotate at the same time, which is more stable, and multiple oil-absorbing papers 4 are adsorbed at intervals, which not only ensures the adsorption degree but also improves the adsorption efficiency. After use, the electric cylinder 34 is used to drive the top mounting ring 31 to move up to keep it away from the water surface, and the top of the clamping block 371 is manually pressed to drive the bottom of the clamping block 371 to tilt away from the oil-absorbing paper 4, and the oil-absorbing paper 4 is removed for replacement. After the new oil-absorbing paper 4 is placed, the clamping block 371 is released, and the spring 372 is deformed and reset, driving the clamping block 371 to reset, so that the clamping block 371 clamps the oil-absorbing paper 4 for subsequent use.
