Description

Technical Field

[0001] This invention relates to the field of synchronous gear assembly technology, and in particular to a cleaning device for synchronous gear assembly. Background Technology

[0002] Synchronizing gear sleeves are a type of transmission gear assembly, commonly used in the internal transmission components of internal combustion engines and gearboxes. The synchronizer sleeve contains a gear ring that synchronizes the engagement of two gear sets waiting to mesh. It is an indispensable component in transmission assemblies. During the assembly of the synchronizer sleeve, due to the precision of the gearbox's internal structure, even the slightest debris cannot be present, otherwise it will affect its service life. Synchronizing gear sleeves require cleaning before assembly, typically using an oil bath. The cleaning oil washes away surface debris and also serves as a pre-lubrication process during assembly.

[0003] The existing synchronous gear sleeves have the following problems during assembly: Currently, there is no specialized equipment for cleaning the synchronous gear sleeves during assembly. They are usually simply soaked in a basin and shaken a few times before being removed and assembled. Some are even directly installed after being cleaned with an air gun. Therefore, the existing technology lacks a dedicated cleaning tool for synchronous gear sleeves to effectively wash away oil from their surface. This problem is difficult to solve with current technology. Therefore, a cleaning device for synchronous gear sleeves before assembly is urgently needed to address these issues. Summary of the Invention

[0004] To address the current lack of specialized cleaning tools for synchronizing gear sleeves to rinse their surface with oil, this invention proposes a cleaning device for synchronizing gear sleeves before assembly.

[0005] This invention proposes a cleaning device for synchronizing gear sleeves before assembly, comprising a cleaning chamber with a hollow oil chamber at the top. A sealing top ring is bolted to the top circumference of the cleaning chamber, and a fixed cover is fixed to the top of the sealing top ring. The fixed cover and the sealing top ring are welded together. A transparent cover is hinged to the top of the fixed cover, and the transparent cover and the fixed cover are sealed together. When closed, the bottom of the transparent cover seals with the top of the sealing top ring. A handle is fixed to the bottom circumference of the transparent cover. Four circumferentially arranged lifting side slots are formed on the inner wall of the cleaning chamber. A flushing screen is slidably engaged between the inner walls of the four lifting side slots. Lifting sliders are provided on the circumference of the flushing screen at the positions of the four lifting side slots, and the lifting sliders are slidably engaged with the lifting side slots. A flushing plate hole is formed on the top of the flushing screen. A fixing post is bolted to the top of the flushing screen, and a support frame is bolted between the tops of the fixing posts.

[0006] Preferably, the top of the support frame is provided with a ball groove, and a rolling ball head is rolled and fitted inside the ball groove. A horizontal synchronous gear sleeve body is placed on top of the rolling ball head on the support frame.

[0007] Preferably, a first electric push rod is fixed to the bottom inner wall of the cleaning machine box at the bottom position of the lifting side slot by bolts, and the top output shaft of the first electric push rod is in contact with but not fixed to the bottom of the lifting slider. A return spring is fixed to the bottom inner wall of the cleaning machine box at the circumference of the first electric push rod by bolts, and the top of the return spring is fixed to the bottom of the lifting slider.

[0008] Preferably, the inner circumferential wall of the cleaning chamber is provided with four circumferentially arrayed fixed claw grooves, and the lifting side slots are staggered with the fixed claw grooves. Vertically arranged fixed claws are fixed between the bottom inner walls of the fixed claw grooves by bearings. The rotating shaft of the fixed claw is located on one side inner wall of the fixed claw groove and is fixed with a coil spring by bolts. A fixed claw head is provided at the top of the fixed claw.

[0009] Preferably, the fixed claw and the fixed claw head are provided with the same linkage housing at the middle position. The linkage housing is fixed with a limit block inside. The fixed claw and the fixed claw head are both fixed with vertically arranged limit rods and linkage teeth. The limit rods and linkage teeth inside the fixed claw and the fixed claw head are staggered and are slidably sleeved with the limit block. The limit block is provided with an intermediate gear inside. The two linkage teeth mesh with the two sides of the intermediate gear respectively.

[0010] Preferably, the top of the rinsing screen plate has an arc-shaped through hole at the circumferential position. A vertically arranged arc-shaped flushing box is fixed to the top of the rinsing screen plate at the position of the arc-shaped through hole by bolts. The side of the arc-shaped flushing box facing the center is set as the drain end. The bottom of the arc-shaped flushing box has a liquid inlet, which is connected to the arc-shaped through hole. A vertically arranged fixed end post is fixed to the side of the arc-shaped flushing box at the drain end. The fixed end posts are arranged in an array along the inner arc edge of the arc-shaped flushing box. A vertical drain groove is formed between two adjacent fixed end posts. The drain groove is connected to the interior of the arc-shaped flushing box.

[0011] Preferably, a vertically arranged swing fin is fixed between the top and bottom of the drain outlet via a bearing. A fixed shaft is welded to both the top and bottom of the swing fin. The fixed shaft is sleeved with the inner wall of the arc-shaped punch box via a bearing. A servo motor is fixed to the fixed shaft at the bottom inner wall of the arc-shaped punch box. Magnetic springs are fixed to the inner walls on both sides of the swing fin. A sealing outer adhesive layer is provided on both sides of the swing fin. The middle position of the inner wall of the outer adhesive layer is bonded and fixed to the middle position of the magnetic spring.

[0012] Preferably, a vertical groove is formed between the top and bottom of the fixed end post, and a magnetic post is placed inside the groove. The magnetic properties of the magnetic spring and the magnetic post are set to be opposite.

[0013] Preferably, the top inner wall of the rinsing mesh plate has an inner groove, and a horizontal sealing plate is slidably arranged between the inner walls of the two sides of the inner groove. A blocking piece is arranged in the middle of the sealing plate, and the size of the blocking piece is slightly larger than the opening size of the rinsing plate hole. A second electric push rod is fixed on both sides of the inner wall at one end of the inner groove, and the output shafts of the two second electric push rods are respectively fixed to the two sides of the sealing plate.

[0014] Preferably, the bottom opening size of the flushing plate hole is larger than the top opening size.

[0015] The beneficial effects of this invention are as follows:

[0016] The cleaning device before assembling the synchronous gear sleeve uses cleaning oil sprayed from the flushing plate holes. Because the bottom opening of the flushing plate holes is larger than the top opening, the cleaning oil sprayed from the top has a high flow rate, which flushes the inner and outer circumference of the synchronous gear sleeve body. As the synchronous gear sleeve body moves downward, it impacts the cleaning oil, thereby washing away impurities from the surface of the synchronous gear sleeve body.

[0017] The cleaning device before assembling the synchronous gear sleeve uses a curved punch to spray cleaning oil. Inside the punch, a servo motor controls the swing fin to swing to one side. At this time, due to the repulsion of like poles, the magnetic spring and outer rubber layer on the side near the fixed end post retract inward, while the magnetic spring and outer rubber layer on the other side are unaffected and protrude outward. The curved surface on this side is more pronounced than that on the other side, allowing for a faster flow of the cleaning oil. Due to the guidance of the swing fin and the increased spray speed, the cleaning oil sprayed from the curved punch acts on the circumference of the synchronous gear sleeve, causing it to rotate in a circular motion, thus improving the surface cleaning effect.

[0018] Before the synchronous gear sleeve is assembled, the cleaning device has four fixing claws installed on the circumference of the cleaning machine box. Due to the bottom coil spring, these claws move closer to the center and remain in contact with the circumference of the washing screen as the synchronous gear sleeve body descends. The deeper the descent, the more the fixing claws tilt downwards and converge at the top of the synchronous gear sleeve body. The top fixing claws form a blocking area at the top of the synchronous gear sleeve body, preventing the synchronous gear sleeve body at the bottom from being blown away by the force during the washing process. This ensures the stability of the synchronous gear sleeve body during the cleaning process. After the washing is completed, the claws gradually retract into the grooves of the fixing claws as the washing screen rises.

[0019] The cleaning device before assembling the synchronous gear sleeve uses a second electric push rod to push the sealing plate that is engaged in the inner groove of the flushing screen. When the cleaning oil needs a greater flushing effect, the sealing plate temporarily closes the flushing plate hole and opens the flushing plate hole intermittently to obtain a greater flushing pressure when the flushing screen is pressed down, thus cleaning the synchronous gear sleeve body that needs deep cleaning and lubrication.

[0038] Furthermore, the top of the rinsing screen plate 6 is provided with an arc-shaped through hole at the circumference position. The top of the rinsing screen plate 6 is fixed with bolts at the position of the arc-shaped through hole. The side of the arc-shaped flushing box 10 facing the center is set as the drain end. The bottom of the arc-shaped flushing box 10 is provided with a liquid inlet 25, and the liquid inlet 25 is connected to the arc-shaped through hole. The side of the arc-shaped flushing box 10 located at the drain end is fixed with a vertically arranged fixed end post 14, and the fixed end post 14 is arranged in an array along the inner arc edge of the arc-shaped flushing box 10. A vertical drain groove 24 is formed between two adjacent fixed end posts 14, and the drain groove 24 is connected to the interior of the arc-shaped flushing box 10.

[0039] Furthermore, a vertically arranged swing fin 15 is fixed between the top and bottom of the drain outlet 24 via a bearing. A fixed shaft 27 is welded to both the top and bottom of the swing fin 15. The fixed shaft 27 is sleeved with the inner wall of the arc-shaped punch box 10 via a bearing. A servo motor is fixed at the bottom inner wall of the arc-shaped punch box 10 via the fixed shaft 27. Magnetic springs 28 are fixed to the inner walls on both sides of the swing fin 15. A sealing outer adhesive layer 29 is provided on both sides of the swing fin 15. The middle position of the inner wall of the outer adhesive layer 29 is bonded and fixed to the middle position of the magnetic spring 28.

[0040] Furthermore, a vertical groove is provided between the top and bottom of the fixed end post 14, and a magnetic post 26 is placed inside the groove. The magnetism of the magnetic spring 28 and the magnetism of the magnetic post 26 are set to be opposite.

[0041] Furthermore, the bottom opening size of the flushing plate hole 7 is larger than the top opening size.

[0042] When using this invention: The entire cleaning device is placed horizontally in the workshop. Before use, cleaning oil is poured into the oil chamber 22 inside the cleaning machine box 1. Before assembling the synchronous gear sleeve, the transparent cover 3 is opened, and the synchronous gear sleeve body 12 is placed horizontally on top of the support frame 5. Then the transparent cover 3 is closed to keep the inside sealed and prevent the oil from spraying out of the device during the cleaning process. During the cleaning process, the first electric push rod 21 is pushed up to push the flushing screen plate 6 and the synchronous gear sleeve body 12 at the top to the highest position. Then the work is stopped. The flushing screen plate 6 and the synchronous gear sleeve body 12 at the top are pulled down by the pull of the reset spring 20 at the bottom. Since the cleaning oil has a certain viscosity, the downward pull makes the cleaning oil spray out to the top through the flushing plate hole 7 and the arc-shaped flushing box 10 at the circumference.

[0043] The cleaning oil sprayed through the flushing plate hole 7 has a high flow rate because the bottom opening of the flushing plate hole 7 is larger than the top opening. This process flushes the inner and outer circumference of the synchronous gear sleeve body 12. As the synchronous gear sleeve body 12 moves downward, it impacts the cleaning oil, thereby washing away impurities on the surface of the synchronous gear sleeve body 12.

[0044] The cleaning oil sprayed from the arc-shaped punch 10 causes the servo motor inside the arc-shaped punch 10 to control the swing fin 15 to swing to one side. At this time, due to the repulsion of like poles, the magnetic spring 28 on the side near the fixed end post 14, along with the outer rubber layer 29, retracts inward. The magnetic spring 28 and the outer rubber layer 29 on the other side are unaffected and protrude outward. The arc surface on this side is more obvious than the arc surface on the other side, which can achieve a faster flow effect when the cleaning oil is discharged. Due to the guidance of the swing fin 15 and the increased spray speed, the cleaning oil sprayed from the arc-shaped punch 10 acts on the circumference of the synchronous gear sleeve body 12, which can make it rotate in a circular state, thus improving the surface cleaning effect.

[0045] As the synchronous gear sleeve body 12 descends with the rinsing screen plate 6, the four fixing claws 18 installed on the circumference of the cleaning machine housing 1 move closer to the center due to the bottom coil spring 23, and always remain in contact with the circumference of the rinsing screen plate 6. The deeper the descent, the lower the fixing claws 18 tilt downwards and converge at the top of the synchronous gear sleeve body 12. As the descent continues, the top fixing claw head 19 descends, and due to gravity, the extension of the two linkage rods 34 and the limiting rod 33 ensures that the extended fixing claws 18 and the fixed claw head 19 still have a clamping effect on the synchronous gear sleeve body 12. Furthermore, the top fixing claw head 19 forms a blocking area at the top of the synchronous gear sleeve body 12, preventing the bottom synchronous gear sleeve body 12 from being blown away by the force during the rinsing process, thus ensuring the stability of the synchronous gear sleeve body 12 during the rinsing process. After rinsing, as the rinsing screen plate 6 rises, the fixing claws 18 gradually retract into the interior of the fixing claw groove 17.

[0046] Example 2: Refer to Figures 1-12 A cleaning device for synchronizing gear sleeves before assembly, which is further included in this embodiment compared to embodiment 1.

[0047] The top inner wall of the rinsing screen plate 6 is provided with a screen plate inner groove 30. A horizontal sealing plate 31 is slidably arranged between the inner walls of the two sides of the screen plate inner groove 30. A blocking piece is provided in the middle of the sealing plate 31, and the size of the blocking piece is slightly larger than the opening size of the rinsing plate hole 7. A second electric push rod 32 is fixed on both sides of the inner wall of one end of the screen plate inner groove 30, and the output shafts of the two second electric push rods 32 are respectively fixed to the two sides of the sealing plate 31.

[0048] When this invention is used: the second electric push rod 32 can push the blocking plate 31 that is engaged in the inner groove 30 of the inner mesh plate of the flushing mesh plate 6. When the cleaning oil needs a greater flushing effect, the blocking plate 31 temporarily closes the flushing plate hole 7 and opens the flushing plate hole 7 intermittently to obtain a greater flushing pressure when the flushing mesh plate 6 is pressed down, so as to clean the synchronous gear sleeve body 12 that needs deep cleaning and lubrication.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
