Description

Technical Field

[0001] This utility model relates to the field of hydraulic brake system technology, specifically to a simple oil pipe and needle riveting device. Background Technology

[0002] In hydraulic braking systems, the hydraulic hoses connect the brake lever and the brake pump at both ends. To prevent leakage of the hydraulic fluid inside the hoses and to allow for quick assembly, needle pins are typically installed at both ends. The traditional connection method involves inserting the needle pin's connector directly into the free end of the hose, relying on friction and tightening forces to maintain the connection. However, in practical applications, especially in high-frequency vibration scenarios such as bicycles, this simple insertion method cannot guarantee a stable connection over the long term.

[0003] With technological advancements, the industry has gradually adopted a solution of attaching a reinforcing sleeve to the end of the oil pipe. Applying riveting force to the reinforcing sleeve causes it to deform, thus creating a more stable bond between the oil needle and the free end of the oil pipe. This improvement effectively enhances connection stability; however, existing riveting equipment still has shortcomings in long-term performance, mainly in the following aspects: existing riveting mechanisms cannot ensure a uniform distribution of riveting force, leading to uneven deformation of the reinforcing sleeve, which may loosen under long-term vibration conditions. Furthermore, the riveting process can easily damage the oil pipe and oil needle. In addition, existing equipment generally uses complex hydraulic or pneumatic drive systems, resulting in bulky equipment, high maintenance costs, and difficulty in adapting to the needs of small-batch flexible production. These technical deficiencies directly affect the reliability and service life of the hydraulic braking system.

[0004] Therefore, we propose a simple oil pipe and needle riveting device. Utility Model Content

[0005] This application provides a simple oil pipe and needle riveting device, which has the advantages of maintaining uniform riveting force, avoiding damage to the oil pipe and needle, and having a compact structure and easy operation.

[0006] This application provides a simple oil pipe and needle riveting device, which is used in conjunction with an oil pipe fitting, an oil needle fitting, and a reinforcing sleeve. The reinforcing sleeve is fitted onto the free end of the oil pipe fitting, and the first end of the oil needle fitting is inserted into the free end of the oil pipe fitting. The device includes:

[0007] The drive housing has an axially formed annular groove in its middle part, and the inner wall of the annular groove has a number of unidirectional bevel teeth arranged in the same direction in a ring array.

[0008] A riveting component is disposed within the annular groove and includes at least a plurality of riveting movable bodies arranged in a circular array. The inner end of each riveting movable body has a riveting tooth, and its outer end abuts against the unidirectional bevel tooth.

[0009] A fixed housing is disposed on one axial side of the drive housing and rotatably assembled with the drive housing;

[0010] The unidirectional rotation of the drive housing causes multiple unidirectional slope teeth to rotate in an increasing slope direction, squeezing several riveting moving bodies to move synchronously towards the center, thereby compressing the reinforcing sleeve to deform and fixing the oil pipe and oil needle components.

[0011] Optionally, the riveting component further includes:

[0012] The riveting disc body has its first end fixedly assembled to the fixed housing by a number of first bolts, and a riveting station is provided in the axial center of the disc body.

The riveting movable body is movably assembled in the riveting movable groove.

[0013] The limiting post has several ends, the first end of which is fixed to the side of the riveting movable body near the riveting disc, and the second end of which is movably fitted into the first strip groove opened on the bottom wall of the riveting movable groove to limit the radial movement stroke of the riveting movable body.

[0014] The second strip groove, which is several in number and arranged in a circular array, is matched and set on the first end face of the riveting disc body corresponding to the position of the first strip groove and is respectively connected to the first strip groove.

[0015] The first elastic element, which is several in number and is respectively disposed in the second strip groove, has its two ends abutting against the bottom wall of the second strip groove and the second end of the limiting post extending into the second strip groove to provide the elastic restoring force of the riveting movable body.

[0016] Optionally, a bearing assembly groove is radially formed at the outer end of the riveting movable body, and a bearing component is rotatably sleeved on the limiting post in the bearing assembly groove, and the outer edge of the bearing component is in rolling contact with the one-way slope tooth.

[0017] Both sides of the riveting groove are provided with bearing grooves that match the rolling assembly of the outer edge of the bearing component.

[0018] Optionally, the second end of the riveting disc is fixed to a follower housing by a plurality of second bolts. The follower housing is annular and rotates with the other side of the drive housing along its axial direction.

[0019] Optionally, a drive unit for driving the drive housing to rotate unidirectionally is radially fixed on the drive housing.

[0020] Optionally, the fixed housing is provided with a first assembly part, which cooperates with a second assembly part provided on a frame to install and fix the riveting device.

[0021] Optionally, an oil syringe is axially fixed to the fixed housing at the position corresponding to the riveting station, so as to accommodate the oil syringe and position the riveting position of the reinforcing sleeve during riveting.

[0022] Compared with related technologies, the simplified oil pipe and needle riveting device provided in this application has at least the following technical advantages:

[0023] Through the coordinated operation of the unidirectional bevel teeth and the riveting parts, the drive housing rotates, causing multiple unidirectional bevel teeth to rotate in an increasing direction of slope. This uniformly and synchronously compresses multiple riveting moving parts, causing synchronous radial movement towards the center to compress the reinforcing sleeve and deform it evenly, thus achieving the riveting of the reinforcing sleeve. This ensures that the force at each riveting point is consistent, effectively improving the connection stability of the connection structure. Moreover, the unidirectional drive mechanism ensures that the riveting process is stable and controllable, effectively reducing the risk of accidental damage to the oil pipe and oil needle. At the same time, the overall device structure is simplified, achieving a compact structural layout and reducing the manufacturing cost of the riveting equipment.

[0042] In related technologies, the industry has gradually adopted a solution of attaching a reinforcing sleeve to the end of the tubing. By applying riveting force to the reinforcing sleeve, it deforms, thereby forming a more stable bond between the needle and the free end of the tubing. This improvement effectively enhances connection stability, but existing riveting equipment still has shortcomings in terms of long-term performance. These shortcomings are mainly: existing riveting mechanisms cannot ensure a uniform distribution of riveting force, resulting in uneven deformation of the reinforcing sleeve, which may loosen under long-term vibration; the riveting process can easily damage the tubing and needle; and the equipment is generally large in size and has a high cost.

[0043] Based on the above, this utility model provides a simple oil pipe and needle riveting device, which will be described in detail below with reference to specific embodiments and accompanying drawings.

[0044] Example 1

[0045] Embodiment 1 of this utility model provides a simple oil pipe and oil needle riveting device. Figure 1 This is one of the perspective views of a simplified oil pipe and needle riveting device according to an exemplary embodiment. Figure 2 This is one of the perspective views of a simplified oil pipe and needle riveting device according to an exemplary embodiment. Figure 3 This is a cross-sectional view of a simplified oil pipe and needle riveting device according to an exemplary embodiment. Figure 4 This is an exploded view of a simplified oil pipe and needle riveting device according to an exemplary embodiment. Figures 1-4 As shown, the riveting device is used in conjunction with an oil pipe fitting a, an oil needle fitting c, and a reinforcing sleeve b. The reinforcing sleeve b is fitted onto the free end of the oil pipe fitting a, and the first end of the oil needle fitting c is inserted into the free end of the oil pipe fitting a. The device includes:

[0046] The drive housing 10 has an annular groove 102 axially formed in its middle part, and a number of unidirectional slope teeth 103 distributed in the same direction are arranged in an annular array on the inner wall of the annular groove 102.

[0047] The riveting component 20 is disposed in an annular groove and includes at least a plurality of riveting movable bodies 201 arranged in an annular array. The inner end of the riveting movable body 201 has a riveting tooth 2011, and its outer end abuts against a one-way slope tooth 103. In this embodiment, the riveting tooth 2011 is prismatic.

[0048] A fixed housing 40 is disposed on one axial side of the drive housing 10 and rotatably assembled with the drive housing 10;

[0049] The unidirectional rotation of the drive housing 10 causes multiple unidirectional slope teeth 103 to rotate in the direction of increasing slope, which in turn compresses several riveting movable bodies 201 to move synchronously in a centripetal motion, thereby compressing the reinforcing sleeve b to deform and fixing the oil pipe a and the oil needle c.

[0050] In the above embodiment, after the reinforcing sleeve b is fitted onto the free end of the tubing component a, it is assembled with the oil needle component c and placed at the riveting station 2021. When the drive housing 10 is driven to rotate in one direction, multiple unidirectional slope teeth 103 rotate along the increasing slope direction, pushing the outer end of the corresponding riveting movable body 201. The increasing height of the unidirectional slope teeth 103 changes continuously, so that each riveting movable body 201 is subjected to uniform radial extrusion force. The riveting teeth 2011 compress the reinforcing sleeve b to produce uniform plastic deformation, so that the tubing component a and the oil needle component c form a stable connection. The technical solution of this application embodiment transforms the rotational motion into the synchronous radial motion of multiple riveting movable bodies 201, realizing the uniform deformation of the reinforcing sleeve b, ensuring that the force on each riveting point is consistent, effectively improving the connection stability performance of the connection structure, and the unidirectional drive mechanism ensures that the riveting process is stable and controllable, effectively reducing the risk of accidental damage to the tubing and oil needle. At the same time, the overall device structure is simplified, realizing a compact structural layout and reducing the manufacturing cost of the riveting equipment.

[0051] In this embodiment, Figure 5 This is one of the exploded views of a riveting component shown according to an exemplary embodiment. Figure 6 This is a second exploded view of a riveted component according to an exemplary embodiment. (Refer to...) Figure 5-6 The riveting component 20 also includes:

[0052] The riveting disc 202 has its first end fixedly assembled to the fixed housing 40 by a number of first bolts 401. A riveting station 2021 is provided in the middle of its axial direction, and a number of riveting movable grooves 2022 arranged in a ring array are provided radially on the annular outer wall of its second end. The riveting movable body 201 is movably assembled in the riveting movable groove 2022.

[0053] The limiting post 203 is a plurality of such posts. Its first end is fixed to the side of the riveting movable body 201 near the riveting disc body 202, and its second end is movably fitted into the first strip groove 2023 opened on the bottom wall of the riveting movable groove 2022 to limit the radial movement of the riveting movable body 201. In this embodiment, the limiting post 203 may specifically be a cylindrical pin.

[0054] The second strip groove 2024, which is a number of them and is distributed in a ring array, is matched and set on the first end face of the riveting disc 202 corresponding to the position of the first strip groove 2023 and is respectively connected to the first strip groove 2023.

[0055] The first elastic element 204, which is a plurality of them, is respectively disposed in the second strip groove 2024. Its two ends respectively abut against the bottom wall of the second strip groove 2024 and the second end of the limiting post 203 extending into the second strip groove 2024 to provide elastic restoring force for the riveting movable body. In this embodiment, the first elastic element 204 is a helical spring or an elastic rubber column, which stores elastic potential energy in a pre-compressed state to drive the riveting movable body 201 to reset.

[0056] In the above embodiment, when the drive housing 10 drives the unidirectional slope tooth 103 to rotate, the slope increasing structure pushes the outer end of the riveting movable body 201, causing it to move along the riveting movable groove 2022 toward the center of the riveting station 2021; the end of the limiting post 203 slides in the composite guide groove formed by the first strip groove 2023 and the second strip groove 2024, which limits the maximum stroke of the riveting movable body 201 and avoids deflection during the movement; the first elastic element 204 is compressed when the riveting movable body 201 moves centripetally, and when the riveting movable body 201 contacts the slope starting point of the next unidirectional slope tooth 103, the first elastic element 204 releases the stored elastic force to push the riveting movable body 201 back to the initial position, ensuring that multiple riveting movable bodies 201 maintain synchronous movement during the riveting process. The technical solution of this application embodiment can solve the problem of inconsistent deformation of the reinforcing sleeve b caused by uneven riveting force distribution. In addition, with the elastic reset mechanism, it automatically restores the initial state after riveting is completed, preventing jamming from affecting continuous operation. Thus, while ensuring riveting accuracy, it reduces the complexity of equipment maintenance and is suitable for industrial continuous production scenarios.

[0057] In this embodiment, please continue to refer to the appendix. Figure 5-6 A bearing assembly groove 2012 is radially opened at the outer end of the riveted movable body 201. A bearing component 205 is rotatably sleeved on the limiting post 203 in the bearing assembly groove 2012. The outer edge of the bearing component 205 is in rolling contact with the one-way slope tooth 103.

[0058] Both sides of the riveting groove 2022 are provided with bearing grooves 2025 for rolling assembly of the outer edge of the matching bearing component 205.

[0059] In the above embodiment, when the drive housing 10 is driven by an external force to rotate in one direction, the unidirectional slope teeth 103 distributed in a ring array sequentially contact the outer edge of the bearing component 205. The increasing slope of the unidirectional slope teeth 103 pushes the riveting movable body 201 to move radially and centripetally along the riveting movable groove 2022 through rolling contact. During this process, the rolling trajectory of the bearing component 205 in the bearing movable groove 2025 is constrained, ensuring that the riveting teeth 2011 of all riveting movable bodies 201 synchronously and uniformly press the reinforcing sleeve b, thereby effectively converting sliding friction into rolling friction, reducing motion resistance, and avoiding abnormal wear of the contact surface between the riveting movable body 2101 and the riveting movable groove 2022, thus ensuring the stability of the riveting operation in a long-term working environment.

[0060] In this embodiment, please continue to refer to the appendix. Figure 5-6 The second end of the riveting disc 202 is fixed to a follower housing 30 by a number of second bolts 301. The follower housing 30 is annular and rotates with the other side of the drive housing 10. In this embodiment, when the drive housing 10 is rotated in one direction by external force, the follower housing 30 and the fixed housing 40 form a bidirectional axial support for the drive housing 10 through rotational engagement, which prevents the drive housing 10 from radially offset during rotation and ensures that the riveting force is evenly transmitted to the reinforcing sleeve b. At the same time, the riveting disc 202 remains stationary during the riveting process, which ensures that the centripetal motion trajectory of the riveting moving body 201 is stable. At the same time, the axial dimension of the overall device is reduced by the split housing design.

[0061] In this embodiment, please continue to refer to the appendix. Figure 1-2 A drive unit 101 for driving the drive housing 10 to rotate in one direction is radially fixed on the drive housing 10. In this embodiment, the drive unit 101 is a drive arm structure, which can be manually rotated or connected to an external power source (such as a motor) to realize rapid and continuous industrial processing.

[0062] In this embodiment, please continue to refer to the appendix. Figure 1-6 The fixed housing 40 is provided with a first assembly part 402. The first assembly part 402 cooperates with a second assembly part provided on a frame to install and fix the riveting device. In this example, the first assembly part 402 is cylindrical and the second assembly part is rod-shaped. During assembly, the second assembly part is inserted into the first assembly part 402 to fix the riveting device on the frame.

[0063] Example 2

[0064] The difference between Embodiment 2 and Embodiment 1 is that an oil syringe 50 is axially fixed to the fixed housing 40 at the position corresponding to the riveting station 2021, so as to accommodate the oil needle c and position the riveting position of the reinforcing sleeve b during riveting. During the riveting process, the oil needle c passes through the riveting station 2021 and reaches the oil syringe 50 and abuts against the end of the inner cavity of the oil syringe 50. At this time, the deformation area of ​​the reinforcing sleeve b is precisely controlled at the riveting station 2021, forming a rapid workpiece positioning.

[0065] Other undescribed structures are described in Example 1.

[0066] In summary, the simplified oil pipe and needle riveting device provided in this embodiment of the present invention, through the coordinated cooperation of unidirectional bevel teeth and riveting parts, drives the housing to rotate, causing multiple unidirectional bevel teeth to rotate in an increasing bevel direction. This uniformly and synchronously compresses multiple riveting moving bodies to undergo synchronous radial movement towards the center, thereby compressing the reinforcing sleeve to undergo uniform deformation under pressure, achieving the riveting of the reinforcing sleeve. This ensures that the force at each riveting point is consistent, effectively improving the connection stability of the connection structure. Furthermore, the unidirectional drive mechanism ensures that the riveting process is stable and controllable, effectively reducing the risk of accidental damage to the oil pipe and needle. At the same time, the overall device structure is simplified, achieving a compact structural layout and reducing the manufacturing cost of the riveting equipment.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
