Technical Field

[0001] This utility model relates to the field of shock absorber processing technology, and in particular to a press-fitting device for assembling front fork tube assemblies. Background Technology

[0002] The fork tube assembly of this technology is mainly used in electric two-wheeled or three-wheeled vehicles, and is also suitable for some small electric four-wheeled vehicles. For example... Figure 1 As shown, the fork tube assembly 300 includes a (hollow) fork connecting tube 301 and a fork connecting seat 302, with two fork limiting posts 303 provided on the fork connecting seat 302. After the fork connecting tube 301 and the fork connecting seat 302 are manufactured separately, the fork connecting seat 302 needs to be installed on the fork connecting tube 301, that is, the fork connecting seat 302 is pressed into the end of the fork connecting tube 301, and the connection between the fork connecting tube 301 and the fork connecting seat 302 is welded to ensure its connection reliability. Currently, there is no corresponding pressing equipment in the prior art; only traditional hydraulic equipment is used, which has low precision and low assembly efficiency.

[0003] Therefore, there is an urgent need to propose a press-fitting device for assembling front fork tube components that is simple in structure and reliable in assembly. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a press-fitting device for assembling front fork tube assemblies. The technical solution adopted by this utility model is as follows: A press-fitting device for assembling a fork tube assembly is disclosed, which presses a fork connector onto a fork connecting tube to obtain a fork tube assembly. The press-fitting device includes an upper mounting plate, a pressure sensor, a pull rod limiting mechanism, a longitudinal sliding assembly, and a pressing mechanism fixed on the upper mounting plate, a lateral sliding assembly disposed on the longitudinal sliding assembly, and a fork connector horizontal adjustment slide assembly disposed on the lateral sliding assembly. The lower part of the fork connecting tube is placed on the pressure sensor and is limited and supported by the pull rod limiting mechanism. The fork connector is disposed on the fork connector horizontal adjustment slide assembly and is shifted and adjusted by the longitudinal sliding assembly, the lateral sliding assembly, and the fork connector horizontal adjustment slide assembly. The pressing mechanism presses the fork connector onto the fork connecting tube.

[0005] Furthermore, the lever limiting mechanism includes a first cylinder mounting seat fixed on the upper mounting plate, a first limiting push cylinder fixed on the first cylinder mounting seat, and a U-shaped limiting post disposed at the front end of the first limiting push cylinder and arranged in the longitudinal direction; the U-shaped limiting post presses against the front fork connecting tube.

[0006] Furthermore, the pressure sensor is provided with several lower end limiting support columns of the fork connecting tube; the fork connecting tube is placed inside the lower end limiting support columns of the fork connecting tube.

[0007] Furthermore, the fork connector horizontal adjustment slide assembly includes a lateral sliding support seat disposed on a lateral sliding assembly, a first guide rail and a first push cylinder disposed on the lateral sliding support seat, and a horizontal sliding seat slidably sleeved on the first guide rail and pushed and moved by the first push cylinder; the fork connector is placed on the horizontal sliding seat and pushed closer to the top of the fork connector tube by the longitudinal sliding assembly, the lateral sliding assembly and the first push cylinder.

[0008] Furthermore, the horizontal sliding seat has two strip grooves; a positioning pin is provided in the strip groove; the positioning pin positions the front fork connecting seat.

[0009] Furthermore, the pressing mechanism includes a second mounting base fixed on the upper mounting plate, a pressing cylinder mounting base disposed on the upper part of the second mounting base, a crossbeam fixed on the lower part of the pressing cylinder mounting base, a pressing cylinder fixed on the pressing cylinder mounting base and passing through the pressing cylinder mounting base and the crossbeam, a sliding sleeve disposed at the end of the crossbeam, a pressing plate disposed at the bottom of the pressing cylinder, and a sliding rod fixed on the pressing plate and slidably sleeved in the sliding sleeve.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This utility model supports the lower part of the front fork connecting tube to be assembled by setting a limiting support column at the lower end of the front fork connecting tube and a tie rod limiting mechanism, ensuring that the front fork connecting tube is arranged in the longitudinal direction, so as to facilitate the subsequent pressing operation of the front fork connecting seat, and then using a pressure sensor to monitor the downward pulling force.

[0011] This invention features a longitudinal sliding component, a lateral sliding component, and a horizontal adjusting slide assembly for the fork connector. These components move the fork connector closer to the top of the fork connecting tube, facilitating reliable assembly between the fork connecting tube and the fork connector. Furthermore, the horizontal sliding base includes a slotted groove and a locating pin, which corresponds one-to-one with the holes on both sides of the fork connector to ensure accurate and reliable positioning. Additionally, the position of the locating pin within the slotted groove is adjustable to accommodate different fork tube assemblies, offering high flexibility.

[0012] In summary, this utility model has the advantages of simple structure and reliable assembly, and has high practical and promotional value in the field of shock absorber processing technology. Attached Figure Description

[0030] In the description of the embodiments in this application, unless otherwise stated, "multiple" means two or more. For example, multiple processing units means two or more processing units; multiple systems means two or more systems.

[0031] like Figures 2 to 11 As shown, this embodiment provides a pressure-welded integrated device for a fork tube assembly. A fork connector 302 is press-fitted onto a fork connector 301 to obtain a fork tube assembly 300, and then the fork tube assembly 300 is welded. Two fork limiting posts 303 are provided on the inner side of the fork connector 302. It should be noted that the fork tube assembly 300 in this embodiment is represented by a simplified diagram.

[0032] Specifically, the press-fitting device for assembling the front fork tube assembly in this embodiment includes a welding fixture assembly 200 and a press-fitting mechanism 100 disposed on the welding fixture assembly 200. An upper platform support 108 is provided between the welding fixture assembly 200 and the press-fitting mechanism 100.

[0033] Here, the pressing mechanism 100 supports the fork connector 302 and the fork connecting tube 301, and presses the fork connector 302 onto the fork connecting tube 301 to obtain the (to be welded) fork tube assembly 300. Specifically, the pressing mechanism 100 includes an upper mounting plate 101, a pressure sensor 102, a pull rod limiting mechanism 103, a longitudinal sliding assembly 104, and a pressing mechanism 107, all fixed to the upper mounting plate 101, a lateral sliding assembly 105 disposed on the longitudinal sliding assembly 104, and a fork connector horizontal adjustment slide assembly 106 disposed on the lateral sliding assembly 105. Several lower end limiting support columns 1021 of the fork connecting tube are provided on the pressure sensor 102. The lower part of the fork connecting tube 301 is inserted into the lower end limiting support columns 1021, and the pressure sensor 102 monitors the pressure during the pressing process. In addition, the tie rod limiting mechanism 103 is used for limiting support to ensure that the fork connecting tube 301 is arranged in the longitudinal direction. Furthermore, the fork connecting seat 302 is arranged on the fork connecting seat horizontal adjustment slide assembly 106, and is moved and adjusted by the longitudinal sliding assembly 104, the lateral sliding assembly 105 and the fork connecting seat horizontal adjustment slide assembly 106. After the fork connecting seat 302 is moved to directly above the fork connecting tube 301 (i.e., the assembly position), the pressing mechanism 107 presses the fork connecting seat 302 onto the fork connecting tube 301.

[0034] Here, the lever limiting mechanism 103 includes a first cylinder mounting seat 1031 fixed on the upper mounting plate 101, a first limiting push cylinder 1032 fixed on the first cylinder mounting seat 1031, and a U-shaped limiting post 1033 disposed at the front end of the first limiting push cylinder 1032 and arranged in the longitudinal direction. The U-shaped limiting post 1033 presses against the front fork connecting tube 301 to ensure that the front fork connecting tube 301 is reliably arranged in the longitudinal direction.

[0035] In this embodiment, the position of the fork connector 302 needs to be adjusted so that it moves directly above the fork connecting tube 301. Here, the fork connector horizontal adjustment slide assembly 106 includes a lateral sliding support 1061 mounted on a lateral sliding assembly 105, a first guide rail 1062 and a first push cylinder 1064 mounted on the lateral sliding support 1061, and a horizontal sliding seat 1063 slidably mounted on the first guide rail 1062 and moved by the first push cylinder 1064. The fork connector 302 is placed on the horizontal sliding seat 1063 and pushed closer to the top of the fork connecting tube 301 by the longitudinal sliding assembly 104, the lateral sliding assembly 105, and the first push cylinder 1064. Since the front fork connector 302 of different models has certain size differences, in order to achieve flexible and reliable assembly, two strip grooves 1065 are provided on the horizontal sliding seat 1063, and a positioning pin 1066 is provided in the strip groove 1065 to position the front fork connector 302.

[0036] After the fork connector 302 is moved to the top of the fork connector tube 301 (assembly position), the pressing mechanism 107 is used for pressing assembly, and the pressure sensor 102 is used for pressure monitoring. Here, the pressing mechanism 107 includes a second mounting base 1071 fixed on the upper mounting plate 101, a pressing cylinder mounting base 1072 set on the upper part of the second mounting base 1071, a crossbeam 1074 fixed on the lower part of the pressing cylinder mounting base 1072, a pressing cylinder 1073 fixed on the pressing cylinder mounting base 1072 and passing through the pressing cylinder mounting base 1072 and the crossbeam 1074, a sliding sleeve 1075 corresponding to the end of the crossbeam 1074, a pressing plate 1077 set at the bottom of the pressing cylinder 1073, and a sliding rod 1076 fixed on the lower part of the pressing plate 1077 and slidably sleeved in the sliding sleeve 1075.

[0037] After the fork connector 302 and the fork connecting tube 301 are assembled together, the connection between the fork connector 302 and the fork connecting tube 301 needs to be welded to ensure reliable connection. Here, the welding fixture assembly 200 includes a lower mounting plate 201, and a fork welding material taking and pressing assembly 202 and a fork connector positioning support assembly 203 respectively fixed to the lower mounting plate 201. The fork welding material taking and pressing assembly 202 takes material from the fork tube assembly 300 on the pressing mechanism 100 and presses the end of the fork connecting tube 301. The fork connector positioning support assembly 203 supports the fork connector 302 and drives the fork connector 302 to tilt or rotate.

[0038] The fork welding material taking and extrusion assembly 202 includes a third mounting base 2021 fixed on the lower mounting plate 201, a first rotary material taking cylinder 2022 fixed on the third mounting base 2021, a rotating plate 2023 disposed on the first rotary material taking cylinder 2022, and a material taking positioning post 2024 disposed on the rotating plate 2023. The material taking positioning post 2024 is sleeved and connected to the end of the fork connecting tube 301. When the material taking positioning post 2024 is arranged in the vertical direction, it takes the (to be welded) fork tube assembly 300 conveyed by the longitudinal sliding assembly 104, the lateral sliding assembly 105, and the fork connecting seat horizontal adjustment slide assembly 106, and rotates it so that the (to be welded) fork tube assembly 300 is arranged in the horizontal direction.

[0039] In this embodiment, two welding support schemes are adopted: The first option: The fork connector positioning support assembly 203 includes a second guide rail 2031 and a push cylinder 2039 fixed on the lower mounting plate 201, a slide plate assembly 2032 slidably sleeved on the second guide rail 2031 and connected to the push cylinder 2039, a rolling shaft drive motor mounting base 2033, a rolling shaft mounting base 2034 and a rotary cylinder 2036 fixed on the slide plate assembly 2032, two rotating rollers 2035 disposed between the top of the rolling shaft drive motor mounting base 2033 and the top of the rolling shaft mounting base 2034, a second rotary cylinder 2037 disposed on the rolling shaft mounting base 2034, and a fork connector positioning support plate 2038 disposed on the second rotary cylinder 2037. The fork connector positioning support plate 2038 supports the limiting post 303 on the fork connector 302 and uses the second rotary cylinder 2037 to tilt the fork connector 302. Here, when the first rotary feed cylinder 2022 drives the fork tube assembly 300 from the longitudinal direction to the horizontal direction, the push cylinder 2039 pushes the slide plate assembly 2032 closer to the fork welding feed extrusion assembly 202 and supports the fork tube assembly 300. During the tilting process of the second rotary cylinder 2037 driving the fork connecting seat 302, welding is performed at the connection between the fork connecting seat 302 and the fork connecting tube 301. The fork connecting tube 301 is positioned between two rotating rollers 2035. For example, the rotary cylinder 2036 presses down on the fork connecting tube 301, and the second rotary cylinder 2037 tilts the fork connecting seat 302. The fork connecting tube 301 is provided with rolling support by the rotating rollers 2035. During the tilting process of the fork connecting seat 302, welding is performed at the connection between the fork connecting tube 301 and the fork connecting seat 302. In this embodiment, a groove 20381 is formed on the positioning support plate 2038 of the front fork connector.

[0040] The second option: The fork connector positioning support assembly 203 includes a second guide rail 2031 and a push cylinder 2039 fixed on the lower mounting plate 201, a slide plate assembly 2032 slidably sleeved on the second guide rail 2031 and connected to the push cylinder 2039, a rolling shaft drive motor mounting base 2033, a rolling shaft mounting base 2034 and a rotary cylinder 2036 fixed on the slide plate assembly 2032, two rotating rollers 2035 disposed between the tops of the rolling shaft drive motor mounting base 2033 and the rolling shaft mounting base 2034, and a rotating roller drive motor 20351 fixed on the rolling shaft drive motor mounting base 2033 and connected to one of the rotating rollers 2035 by a belt. The fork connector tube 301 is positioned between the two rotating rollers 2035 and is driven to rotate by the rotating rollers 2035 and the rotating roller drive motor 20351. A rotary cylinder 2036 is positioned between the rolling shaft drive motor mounting base 2033 and the rolling shaft mounting base 2034, and presses down to clamp the fork connecting tube 301. For example, the rotary cylinder 2036 presses down on the surface of the fork connecting tube 301, while two rotating rollers 2035 and a rotating roller drive motor 20351 provide rolling support, so as to drive the fork connecting tube 301 and the fork connecting seat 302 to rotate one revolution around the axis of the fork connecting tube 301. The welding robot arm can then perform 360° welding at the connection between the fork connecting tube 301 and the fork connecting seat 302. In this case, the second solution is superior to the first solution.

[0041] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
