Description

Technical Field

[0001] The invention relates to the technical field of automobile parts assembly, in particular to an automobile shock absorber oil seal assembly mechanism. Background Art

[0002] Shock absorbers, also known as shock absorbers, are used to suppress the shock when the spring rebounds after absorbing shock and the impact from the road surface, thereby improving the driving smoothness of the car. In the prior art, the assembly of shock absorbers is mostly done manually or with manual assistance. In order to ensure the vibration reduction effect during the use of the shock absorber, no air can enter the shock absorber. Therefore, attention should be paid to the connection accuracy of each component during assembly. However, manual participation in assembly will inevitably lead to deviations, so corresponding improvements need to be made to the existing assembly technology.

[0003] In the prior art, a Chinese invention patent with authorization announcement number CN116728044B discloses an oil seal assembly device, including a workbench and a lifting device arranged on the workbench and moving in a vertical direction, a fixing device for fixing a workpiece is also arranged on the workbench, a connecting shaft with an axis perpendicular to a horizontal plane is arranged at the end of the lifting device, an elastic pressing device for pressing the oil seal and a knocking device for knocking the elastic pressing device are arranged on the connecting shaft, and a linear limiting structure is also arranged on the elastic pressing device. The invention presses the oil seal down by the elastic pressing device for multiple times, and elastic deformation occurs during the pressing process, and then the elastic pressing device is knocked by the knocking device to vibrate, so that the oil seal is vibrated and gradually corrects its posture, and is assembled by the pressure of the elastic pressing device, avoiding the problem of damage caused by direct pressing due to the angle between the center line of the oil seal and the center line of the workpiece during assembly.

[0004] However, the above scheme still has obvious shortcomings. For example, through the above technical scheme, when the elastic pressing device presses down the oil seal for installation, since the oil seal is mostly made of rubber, the oil seal has a certain toughness. Therefore, when the output end of the elastic pressing device is pressed against the inner ring of the oil seal and pressed down, the outer ring of the oil seal is rubbed by the inner wall of the workpiece, causing the oil seal to deform as a whole, thereby resulting in incomplete installation of the oil seal and lack of sealing effect. Moreover, when the sealing ring is pressed vertically, the oil seal needs to overcome a large friction force at one time before it can be installed in place. This may cause the oil seal to be subjected to a large impact and stress concentration during the installation process, thereby affecting its sealing performance and service life. Therefore, the prior art urgently needs a technical solution to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0025] 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.

[0026] like Figures 1 to 6 As shown, the present invention provides an automobile shock absorber oil seal assembly mechanism, including a workbench 1, a workpiece 2 is fixedly mounted on the workbench 1, an oil seal ring 3 is placed on the top of the workpiece 2, a mounting frame 4 is mounted on the workbench 1, a cylinder 5 is inverted on the mounting frame 4, a pressing component 6 is connected to the output end of the cylinder 5, and the pressing component 6 is driven by the cylinder 5 to press against the upper surface of the oil seal ring 3, a flattening component 7 for driving the pressing component 6 to rotate is fixedly mounted on the bottom of the mounting frame 4, and the flattening component 7 cooperates with the pressing component 6 to fix the oil seal ring 3 in the workpiece 2.

[0027] As a further illustration of an embodiment of the present invention, in a general automobile oil seal assembly process, when the elastic pressing device presses down the oil seal for installation, since the oil seal is mostly made of rubber, the oil seal has a certain toughness. Therefore, when the output end of the elastic pressing device is pressed against the inner ring of the oil seal and pressed down, the outer ring of the oil seal is rubbed by the inner wall of the workpiece, causing the oil seal to deform as a whole, thereby resulting in incomplete installation of the oil seal and lack of sealing effect. Moreover, when the sealing ring is pressed down vertically, the oil seal needs to overcome a large friction force at one time to be installed in place, which may cause the oil seal to be subjected to a large impact and stress concentration during the installation process, thereby affecting its sealing performance and service life. In this embodiment, by placing the mounting frame 4 above the workpiece 2, and since the pressing assembly 6 is fixedly mounted on the mounting frame 4, the pressing assembly 6 is driven by the cylinder 5 to install the oil seal ring 3 on the lower workpiece 2 to the workpiece 2, in the process of pressing down the pressing component 6, by adding the rolling component 7, the pressing component 6 can roll and roll the surface of the oil seal ring 3 in the horizontal direction while pressing down, and the multiple rolling output ends of the rolling component 7 evenly roll and roll the upper surface of the oil seal ring 3 close to the periphery, so that the oil seal ring 3 will not be deformed due to uneven force during installation, thereby ensuring the flatness of the installation of the oil seal ring 3, so that the installed oil seal ring 3 has its due sealing effect in the workpiece 2. In addition, when the output end of the rolling component 7 applies a rotational force to the oil seal ring 3, it can drive the oil seal ring 3 to generate a corresponding rotational force. Because the rotational pressing installation helps to reduce the stress concentration of the oil seal ring 3 during the installation process, and makes the oil seal ring 3 fit more evenly on the workpiece 2, the rotational pressing installation method helps to improve the sealing performance and service life of the oil seal ring 3.

[0028] Furthermore, the pressing assembly 6 includes a connecting rod 61 fixedly connected to the output end of the cylinder 5, a connecting ring 62 is rotatably connected to the outer side of the bottom of the connecting rod 61, a plurality of hollow rods 63 are fixedly connected to the connecting ring 62 along the circumferential direction, an extension rod 64 is fixedly connected inside each hollow rod 63, and a flattening roller 73 is rotatably connected to the outside of each extension rod 64.

[0029] Furthermore, the rolling assembly 7 includes a spiral cylinder 71 fixedly mounted on the lower surface of the top of the mounting frame 4, a spiral column 72 is spirally connected inside the spiral cylinder 71, the spiral column 72 is slidably sleeved on the connecting rod 61, and when the cylinder 5 drives the connecting rod 61 to rise and fall, the spiral column 72 rotates in the spiral direction, a planetary gear set 8 is provided at the bottom of the spiral column 72, and the planetary gear set 8 is fixedly connected to the connecting ring 62.

[0030] As a further explanation of the embodiment of the present invention, the pressing component 6 in this embodiment serves as the main body of the overall pressing power, and its output end is a plurality of flattening rollers 73 which directly abut against the surface of the oil sealing ring 3 to push the oil sealing ring 3 into the interior of the workpiece 2. The addition of the flattening component 7 connects the spiral column 72 with the connecting ring 62, thereby driving the connecting ring 62 to rotate with the spiral column 72 during the lifting process. Therefore, when the pressing component 6 is pressed down, the plurality of flattening rollers 73 rotate along the circumferential direction of the spiral column 72 while pressing down, and the surface of the oil sealing ring 3 is rolled and pressed down at a uniform speed, so that the oil sealing ring 3 can be installed into the workpiece 2, thereby improving the sealing performance of the oil sealing ring 3 after installation.

[0031] Furthermore, the planetary gear set 8 includes a toothed disc 81 fixedly connected to the spiral column 72, a planetary carrier 82 fixedly connected to the connecting rod 61, and a plurality of planetary gears 83 rotatably connected to the planetary carrier 82, a sun gear 84 fixedly connected to the top of the connecting ring 62, and each planetary gear 83 meshes with the toothed disc 81 and the sun gear 84 respectively.

[0032] As a further explanation of the embodiment of the present invention, the planetary gear set 8 in the present embodiment connects the spiral column 72 with the connecting ring 62, and fixes the planet carrier 82 with the connecting rod 61. When the toothed disc 81 rotates with the spiral column 72, the sun gear 84 and the connecting ring 62 rotatably connected to the sun gear 84 are increased in speed through the transmission of the multiple planetary gears 83. This driving method is to increase the rotation rate of the connecting ring 62. Because the thread spacing between the spiral column 72 and the threaded sleeve is preset in advance, the connecting ring 62 drives the multiple flattening rollers 7 The rotation angle of the spiral column 72 is directly related to the descending amplitude of the spiral column 72. When the oil seal ring 3 needs to be installed on the top of the workpiece 2, the descending amplitude of the spiral column 72 is not enough to make the rotation angle of the multiple flattening rollers 73 driven by the connecting ring 62 cover the entire surface of the oil seal ring 3. Therefore, a planetary gear set 8 is added between the connecting ring 62 and the spiral column 72 to increase the rotation speed of the connecting ring 62, thereby ensuring that the connecting ring 62 can also drive the rotation angle of the multiple flattening rollers 73 to cover the entire surface of the oil seal ring 3 when the spiral column 72 descends a short distance.

[0033] Furthermore, an elastic adjustment component 9 is provided between the hollow rod 63 and the extension rod 64. The elastic adjustment component 9 includes a dome column 91 slidably mounted on the side wall of the extension rod 64. The side wall of the extension rod 64 is provided with a slot 92 for accommodating the dome column 91. A spring 93 is slidably installed in the slot 92, and one end of the spring 93 is pressed against the bottom of the slot 92, and the other end is pressed against the bottom of the dome column 91. The side wall of the hollow rod 63 is provided with a plurality of openings 94 for the dome column 91 to pass through.

[0034] As a further explanation of an embodiment of the present invention, the elastic adjustment component 9 in this embodiment is used to adjust the elongation of the extension rod 64 so that the rolling range of the multiple flattening rollers 73 on the extension rod 64 is close to the outer circumferential surface of the oil seal ring 3. Because the oil seal ring 3 is customized according to the inner diameter of the workpiece 2, the maximum diameter of the oil seal ring 3 is consistent with the installation diameter of the workpiece 2. Therefore, when the oil seal ring 3 is installed, the outer periphery of the oil seal ring 3 is very likely to deform or warp when rubbing against the inner wall of the workpiece 2, so it is necessary to use the flattening roller 73 to roll and correct it close to the outer periphery of the oil seal ring 3.

[0035] Furthermore, a synchronization component 10 is provided on the bottom end of the connecting rod 61 and the workbench 1, and the synchronization component 10 includes a limit plate 101 fixedly installed on the bottom end of the connecting rod 61 or the bottom of the workbench 1, a rotating plate 103 is rotatably installed on the bottom of the limit plate 101, a plurality of slide rods 105 are slidably installed in the limit plate 101, and the other ends of the slide rods 105 are slidably installed in the rotating plate 103, a limit groove 102 for the slide rod 105 to slide is opened on the limit plate 101, a synchronization groove 104 for the slide rod 105 to slide is opened on the rotating plate 103, and a first motor 106 for driving the rotating plate 103 to rotate is fixedly installed on the bottom of the limit plate 101.

[0036] As a further explanation of an embodiment of the present invention, the working principle of the synchronization component 10 in this embodiment is as follows: the rotating plate 103 is rotatably connected to the limit plate 101, and multiple sliding rods 105 are simultaneously located in the limit groove 102 and the synchronization groove 104. When the rotating plate 103 rotates, the multiple sliding rods 105 located in the synchronization groove 104 slide synchronously along the preset direction of the limit groove 102, thereby realizing the synchronous movement of the multiple sliding rods 105.

[0037] Furthermore, each sliding rod 105 in the synchronization component 10 located at the bottom of the connecting rod 61 is fixedly connected to a top support plate 107, and the multiple top support plates 107 cooperate with each other to press against the inner ring side wall of the oil seal ring 3 and fix the oil seal ring 3. Each sliding rod 105 in the synchronization component 10 located on the workbench 1 is fixedly connected to an arc plate 108, and the multiple arc plates 108 cooperate with each other to press against the outer wall of the workpiece 2 and fix the workpiece 2.

[0038] Furthermore, positioning plates 11 are fixedly installed at both ends of the workbench 1, and a screw 12 is rotatably installed between the two positioning plates 11. A second motor 13 for driving the screw 12 to rotate is fixedly installed on the side wall of one of the positioning plates 11, and the screw 12 is threadedly connected to the mounting frame 4. A baffle 14 is fixedly installed on the workbench 1, and multiple oil sealing rings 3 are stacked in the baffle 14.

[0039] The overall working principle of the present invention is that the second motor 13 can drive the mounting frame 4 to slide back and forth along the axial direction of the screw rod 12, so that the mounting frame 4 slides to the baffle 14. After the cylinder 5 drives the connecting rod 61 to drop to a preset height, the first motor 106 drives multiple supporting plates 107 to press against the inner wall of the oil seal ring 3 to form a fixed clamp for the oil seal ring 3. After the cylinder 5 is contracted and the oil seal ring 3 is lifted, the fixed oil seal ring 3 is driven to the top of the workpiece 2, and the output end of the cylinder 5 is released. After the oil seal ring 3 is close to the top of the workpiece 2, the multiple supporting plates 107 are released from the inner wall of the oil seal ring 3. After the oil seal ring 3 is located at the top of the workpiece 2, the cylinder 5 is started again, and the oil seal ring 3 is installed into the preset point in the workpiece 2 by the pressing component 6 and the flattening component 7 to complete the overall operation.

[0040] The embodiments and / or implementation methods described above are only used to illustrate the preferred embodiments and / or implementation methods for realizing the technology of the present invention, and are not intended to limit the implementation methods of the technology of the present invention in any form. Any technical personnel in this field may make slight changes or modifications to other equivalent embodiments without departing from the scope of the technical means disclosed in the content of the present invention, but they should still be regarded as technologies or embodiments that are essentially the same as the present invention.
