Description

Technical Field

[0001] The invention relates to the field of rubber sealing ring cutting, in particular to a multifunctional automatic cutting machine for rubber sealing rings and a method thereof. Background Art

[0002] The rubber seal is an annular cover composed of one or more parts, fixed on a bearing ring or washer and in contact with another ring or washer or forming a narrow labyrinth gap to prevent lubricating oil leakage and foreign objects from intruding. The rubber seal is a round rubber product, generally used for leak prevention. Natural rubber has high elasticity at room temperature, slightly plastic, very good mechanical strength, small hysteresis loss, low heat generation during multiple deformations, so its flex resistance is also very good, and because it is a non-polar rubber, it has good electrical insulation properties. Before the rubber is made into a rubber seal, it usually needs to be cut.

[0003] In the prior art, during the process of cutting the rubber sealing ring, in order to ensure that the rotating shaft can effectively drive the rubber sealing ring to rotate for easy cutting, the rubber sealing ring needs to be securely mounted on the rotating shaft first.

DETAILED DESCRIPTION

[0017] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit 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.

[0018] For example, see Figure 1-Figure 10 The present invention provides a multifunctional automatic cutting machine for rubber sealing rings and a technical solution thereof: the multifunctional automatic cutting machine for rubber sealing rings comprises: an operating table 1, a controller 2 is fixedly connected to the outer wall of the top of the operating table 1, a base 3 is slidably connected to the outer wall of the top of the operating table 1, a fixed frame 4 is fixedly connected to the top of the base 3, a rotating shaft 5 is arranged on the operating table 1, a rubber ring 7 is movably sleeved on the outer wall of the rotating shaft 5, a cutting assembly 9 is slidably connected to the upper part of the interior of the fixed frame 4, a main shaft 66 is rotatably connected to the interior of the fixed frame 4, a clamping mechanism is arranged inside the fixed frame 4, an outer wall of one side of the upper clamping block 62 is fixedly connected to an installation shell 1 8, an interior of the installation shell 1 8 is rotatably connected to a rotating shaft 2 82, an outer wall of the rotating shaft 2 82 is fixedly connected to a clockwork spring 83, an outer wall of one end of the clockwork spring 83 is fixedly connected to a toothed belt wheel 84, and an outer wall of the toothed belt wheel 84 is fixedly connected to a measuring ruler 81.

[0019] The base 3 drives the fixing frame 4 to move toward the other end of the rotating shaft 5, so that the measuring ruler 81 is gradually lengthened. When the length on the measuring ruler 81 is the length required to cut the rubber ring 7, the movement of the base 3 can be stopped, thereby ensuring that the length of the rubber ring 7 cut is accurate.

[0020] Embodiment 2, on the basis of embodiment 1, the clamping mechanism includes a threaded rod 61, the outer walls of the two threaded rods 61 are slidably connected to the inside of the fixing frame 4, the outer walls of the upper and lower sides of the fixing frame 4 are located on the outer walls of the threaded rods 61 and are fixedly connected to the limiting ring 65, the inner part of the limiting ring 65 is rotatably connected to a threaded sleeve 64, the inner wall of the threaded sleeve 64 is threadedly connected to the outer wall of the threaded rod 61, the outer wall of the threaded sleeve 64 is fixedly connected to the first gear 6, the outer walls of the opposite sides of the two threaded rods 61 are rotatably connected to a shaft sleeve, the outer wall of the top of the shaft sleeve is fixedly connected to a lower clamping block 63, the outer wall of the bottom of the shaft sleeve is fixedly connected to an upper clamping block 62, and the top of the lower clamping block 63 is internally provided with a pressure sensor 21.

[0021] The rubber ring 7 is squeezed by the lower clamping block 63 and the upper clamping block 62 so that the inner wall of the rubber ring 7 fits with the gasket 10, thereby avoiding the generation of a gap between the rubber ring 7 and the gasket 10, making it inconvenient for the rubber ring 7 to rotate with the gasket 10, and correspondingly increasing the contact area and friction between the rubber ring 7 and the gasket 10, so that the rubber ring 7 can rotate more smoothly with the gasket 10.

[0022] Embodiment three, on the basis of embodiment two, a push rod 11 is fixedly connected to the lower part of the outer wall of the threaded rod 61, a T-shaped groove 112 is opened at the upper part of the interior of the fixed frame 4, a striking rod 111 is slidably connected inside the T-shaped groove 112, an outer wall on one side of the striking rod 111 is movably contacted with an outer wall on one side of the upper clamping block 62, a pulling spring 113 is fixedly connected to the outer wall on one side of the striking rod 111, an outer wall at one end of the pulling spring 113 is fixedly connected to the inner wall of the T-shaped groove 112, an outer wall at one end of the push rod 11 is movably contacted with an outer wall on one side of the striking rod 111, a cavity 114 is opened inside the upper clamping block 62, a circular hole 115 is opened on the outer wall at the bottom of the cavity 114, and an interception net is fixedly connected inside the circular hole 115.

[0023] Talc has good lubricity and anti-stickiness, which not only reduces the contact area and friction between the upper clamping block 62 and the rubber ring 7, but also prevents the rubber ring 7 from being stuck to the upper clamping block 62 or generating excessive friction heat during rotation. Although talc reduces the friction between the upper clamping block 62 and the rubber ring 7, the upper clamping block 62 can still squeeze the rubber ring 7. This squeezing effect makes the rubber ring 7 and the gasket 10 fit more closely together, thereby ensuring that the rubber ring 7 can rotate smoothly with the gasket 10.

[0024] Embodiment 4, on the basis of embodiment 1, both ends of the outer wall of the rotating shaft 82 are fixedly connected with eccentric blocks 125, the outer wall of one side of the mounting shell 8 is provided with a strip hole 12, the inner wall of the mounting shell 8 is fixedly connected with a telescopic rod 123, the outer wall of one end of the two telescopic rods 123 is fixedly connected with the mounting shell 121, the interior of the mounting shell 121 is fixedly connected with a push spring 124, the outer wall of the bottom of the push spring 124 is fixedly connected with a movable plate 122, the outer wall of the movable plate 122 is slidably connected with the interior of the mounting shell 121, one side of the mounting shell 121 is fixedly connected with an L-shaped support plate, the outer walls of the opposite sides of the two L-shaped support plates are rotatably connected with rollers 126, and the outer wall of the roller 126 is in active contact with the outer wall of the eccentric block 125.

[0025] By installing the second shell 121 to drive the telescopic rod 123 to stretch, the movable plate 122 can push the cut rubber ring 7, and the rubber ring 7 can be pushed off the gasket 10, so that the operator can collect the cut rubber ring 7. The automatic pushing out of the rubber ring 7 makes the entire workflow smoother and more efficient. The operator does not need to manually take out the rubber ring 7 after cutting, but can directly collect it, thereby saving time and labor costs. At the same time, it prevents the operator from being too close to the cutting component 9 and causing harm to the installation personnel.

[0026] Embodiment 5, on the basis of embodiment 2, a strip groove is provided on the outer wall of the rotating shaft 5, a gasket 10 is slidably connected to the outer wall of the rotating shaft 5, a limiting rod 101 is fixedly connected to the inner wall of the gasket 10, the outer wall of the limiting rod 101 is slidably connected to the inside of the strip groove, a magnetic ring 103 is fixedly connected to the inside of the gasket 10, the outer wall of the top of the lower clamping block 63 is fixedly connected to the magnetic plate 102, the outer wall of the bottom of the upper clamping block 62 is located below the cavity 114 and is fixedly connected to the outer wall of the magnetic plate 102, and the outer wall of the magnetic plate 102 and the outer wall of the magnetic ring 103 are attracted to each other with opposite poles.

[0027] By driving the magnetic ring 103 to move through the magnetic plate 102, the magnetic ring 103 drives the gasket 10 to move on the rotating shaft 5, so that the groove on the gasket 10 can always be aligned with the cutter disc on the cutting component 9, thereby avoiding cutting errors caused by misalignment between the groove and the cutter disc, and correspondingly ensuring the accuracy and consistency of the cutting. The application of the automatic alignment mechanism makes the cutting process more precise and efficient. The operator does not need to manually adjust the position of the gasket 10, and the system can automatically complete the alignment work, thereby saving time and energy and improving cutting efficiency. At the same time, since the cutting accuracy is guaranteed, the quality of the rubber ring 7 is also improved.

[0028] In actual use, when working, first, the rubber ring 7 to be cut is inserted into the upper gasket 10 on the outer wall of the rotating shaft 5, so that one end of the rubber ring 7 is in close contact with one end of the rotating shaft 5. After the rubber ring 7 is put on the rotating shaft 5, the measuring ruler 81 is pulled out from the inside of the mounting shell 8, so that one end of the measuring ruler 81 is hung on the other end of the rubber ring 7, so that the measuring ruler 81 can accurately measure the length of the rubber ring 7 that needs to be cut. Then, the base 3 is pushed, so that the base 3 drives the fixing frame 4 to move toward the other end of the rotating shaft 5, so that the measuring ruler 81 is gradually lengthened. When the length on the measuring ruler 81 is the length that needs to be cut for the rubber ring 7, the movement of the base 3 can be stopped, thereby ensuring the accuracy of the cut length of the rubber ring 7.

[0029] At this time, the motor on the fixed frame 4 is started. Through the fixed connection between the motor and the main shaft 66, the main shaft 66 can move when the motor is working. Then, by utilizing the fixed connection between the main shaft 66 and the second gear, the second gear can be driven to move through the rotation of the main shaft 66. Through the meshing connection between the second gear and the first gear 6, the first gear 6 can be rotated through the rotation of the second gear, so that the clamping mechanism starts to start. By starting the fixing mechanism, the rubber ring 7 can be squeezed, so that the rubber ring 7 and the gasket 10 are tightly fitted, so that the rotating shaft 5 drives the rubber ring 7 to rotate, which is convenient for cutting the rubber ring 7.

[0030] Through the fixed connection between the first gear 6 and the threaded sleeve 64, the threaded sleeve 64 can be driven to rotate when the first gear 6 rotates, and then through the rotation of the threaded sleeve 64, the two threaded rods 61 can drive the upper clamping block 62 and the lower clamping block 63 to move toward the inner or outer wall of the fixing frame 4. When the threaded rod 61 drives the upper clamping block 62 and the lower clamping block 63 to move toward the inner part of the fixing frame 4, the lower clamping block 63 and the upper clamping block 62 can squeeze the rubber ring 7, so that the inner wall of the rubber ring 7 fits with the gasket 10, avoiding the generation of a gap between the rubber ring 7 and the gasket 10, making it inconvenient for the rubber ring 7 to rotate with the gasket 10, and correspondingly increasing the contact area and friction between the rubber ring 7 and the gasket 10, so that the rubber ring 7 can rotate more smoothly with the gasket 10.

[0031] When the threaded rod 61 moves toward the inside of the fixing frame 4, the push rod 11 can be driven to rotate accordingly. When the push rod 11 is separated from the impact rod 111, under the action of the pulling spring 113, the impact rod 111 can be driven to quickly move to one side of the upper clamping block 62 to impact the upper clamping block 62. When the upper clamping block 62 is hit, an instantaneous impact force is generated. This impact force is transmitted in the form of a pressure wave on the upper clamping block 62 and the interception net. When the impact force acts on the interception net, the interception net will be instantly deformed and displaced. This instantaneous deformation and displacement will accelerate the shedding of the powdery substance, and the talcum powder inside the upper clamping block 62 will fall onto the rubber through the interception net on the round hole 115. The friction between the upper clamping block 62 and the rubber ring 7 is further reduced by the provision of talcum powder between the contact surface of the rubber ring 7 and the upper clamping block 62. The talcum powder has good lubricity and anti-stickiness, which not only reduces the contact area and friction between the upper clamping block 62 and the rubber ring 7, but also prevents the rubber ring 7 from being stuck to the upper clamping block 62 or generating excessive friction heat during rotation. Although the talcum powder reduces the friction between the upper clamping block 62 and the rubber ring 7, the upper clamping block 62 can still squeeze the rubber ring 7. This squeezing effect makes the rubber ring 7 and the gasket 10 fit more closely together, thereby ensuring that the rubber ring 7 can rotate smoothly with the gasket 10.

[0032] It should be noted that the contact surface between the upper clamping block 62 and the rubber ring 7 is relatively smooth and flat, which reduces the friction between the upper clamping block 62 and the rubber ring 7, so that the gasket 10 can drive the rubber ring 7 to rotate inside the upper clamping block 62 and the lower clamping block 63.

[0033] By rotating the ball bearings on the lower clamping block 63, the contact area between the lower clamping block 63 and the rubber ring 7 can be reduced, and the original sliding friction can be converted into rolling friction through the rolling motion of the ball bearings, thereby further reducing the friction between the rubber ring 7 and the lower clamping block 63, making it easier for the rubber ring 7 to rotate on the lower clamping block 63. By using the pressure sensor 21 provided on the lower clamping block 63, when the pressing value of the upper clamping block 62 on the rubber ring 7 reaches a preset value, the pressure sensor 21 transmits the contact signal to the controller 2, thereby causing the controller 2 to control the motor to stop moving. This precise control mechanism not only ensures the stability and safety of the rubber ring 7, but also avoids unnecessary energy consumption and wear.

[0034] After the rubber ring 7 and the gasket 10 are fixed, the rotating shaft 5 can be started to rotate, and then the rotating shaft 5 can be rotated to make the limit rod 101 drive the gasket 10 to rotate, and then the close contact between the gasket 10 and the rubber ring 7 can be made to make the gasket 10 drive the rubber ring 7 to rotate, so that the cutting component 9 on one side can cut the rubber ring 7. The cutting speed of the cutting component 9 on the rubber ring 7 can be increased by the rotation of the rubber ring 7. The impact and wear of the cutting component 9 during the cutting process are dispersed to a longer period of time through the continuous rotation of the rubber ring 7, which helps to extend the service life of the cutting component 9 and reduce the replacement frequency and maintenance cost.

[0035] When the rubber ring 7 is cut by the rotation of the knife disc on the cutting component 9, the rubber ring 7 can be isolated from the rotating shaft 5 by the setting of the gasket 10, thereby avoiding direct contact between the rotating shaft 5 and the rubber ring 7. When the cutting component 9 cuts the rubber ring 7, the knife disc on the cutting component 9 will cut the rotating shaft 5, thereby correspondingly increasing the protection of the rotating shaft 5. In addition, a groove is provided on the gasket 10 at the position of the blade, which helps the knife disc to cut the rubber ring 7 more accurately along the groove path, thereby reducing waste and unnecessary energy consumption in the cutting process.

[0036] It should be noted that: by the sliding connection between the cutting assembly 9 and the fixing frame 4 , the position of the cutting assembly 9 can be adjusted according to the thickness of the rubber ring 7 , so that the cutting assembly 9 can penetrate into the interior of the rubber ring 7 .

[0037] When the rubber ring 7 is cut, the threaded rod 61 can be driven by the threaded sleeve 64 to move to the outside of the fixing frame 4, so that the upper clamping block 62 and the lower clamping block 63 can move accordingly, and the pressure of the lower clamping block 63 and the upper clamping block 62 on the rubber ring 7 can be released, so that a gap is left between the rubber ring 7 and the gasket 10, so that the rubber ring 7 and the gasket 10 can be moved separately, so that after the cutting is completed, the rubber ring 7 can be easily separated from the gasket 10, which is convenient for subsequent collection and processing.

[0038] When the upper clamping block 62 moves upward inside the fixing frame 4, it drives the mounting shell 1 8 connected thereto to rise synchronously. This action further releases the fixing constraint of the measuring ruler 81 on the other side of the rubber ring 7. Subsequently, under the elastic potential energy of the spring 83, the toothed belt wheel 84 and the rotating shaft 2 82 begin to rotate in coordination, effectively retracting the measuring ruler 81 to the initial position, thereby reducing manual intervention and simplifying the operation process, thereby enhancing the stability of the system. In addition, the coordinated work of the spring 83, the toothed belt wheel 84 and other components also improves the durability of the system and reduces the risk of component wear and failure caused by frequent operation.

[0039] After the rubber ring 7 is cut, a cutting opening will appear. At this time, under the action of the pushing spring 124, the movable plate 122 can be pushed into the inside of the cutting opening. When the rotating shaft 82 rotates, the eccentric block 125 can be driven to rotate accordingly. Then, through the rotation of the eccentric block 125, when the extended end of the eccentric block 125 contacts the roller 126, the roller 126 is pushed toward the outer wall of the strip hole 12. At this time, the mounting shell 121 drives the telescopic rod 123 to stretch, so that the movable plate 122 can push the cut rubber ring 7, and the rubber ring 7 can be pushed off the gasket 10, so that the operator can collect the cut rubber ring 7. The automatic pushing out of the rubber ring 7 makes the entire workflow smoother and more efficient. The operator does not need to manually take out the rubber ring 7 after the cutting is completed, but can directly collect it, thereby saving time and labor costs. At the same time, it prevents the operator from being too close to the cutting component 9 and causing damage to the installation of the personnel.

[0040] By moving the base 3, the fixing frame 4 can drive the clamping mechanism to move, thereby changing the cutting position of the rubber ring 7, and then through the magnetic plate 102 set on the upper clamping block 62 and the lower clamping block 63, when the upper clamping block 62 and the lower clamping block 63 move, the magnetic plate 102 can drive the magnetic circle 103 to move through the attraction between the opposite poles of the magnetic plate 102 and the magnetic circle 103, so that the magnetic circle 103 drives the gasket 10 to move on the rotating shaft 5, so that the groove on the gasket 10 is always aligned with the cutter disc on the cutting component 9, avoiding the cutting error caused by the misalignment of the groove and the cutter disc, and correspondingly ensuring the accuracy and consistency of the cutting. The application of the automatic alignment mechanism makes the cutting process more precise and efficient. The operator does not need to manually adjust the position of the gasket 10, and the system can automatically complete the alignment work, thereby saving time and energy and improving the cutting efficiency. At the same time, since the cutting accuracy is guaranteed, the quality of the rubber ring 7 is also improved.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
