Description

Technical Field

[0001] This utility model belongs to the field of assembly tooling technology, specifically relating to an assembly tooling for metal pipes and rubber hoses. Background Technology

[0002] The assembly of metal pipes and rubber hoses, that is, the rubber hose being fitted onto the metal pipe, is a common connection method in industrial and mechanical applications.

[0003] In existing technologies, the assembly of metal tubes and hoses typically involves the hose's inner diameter being larger than the metal tube's outer diameter. A common method is to fix the hose in place and then directly push the metal tube into it. However, this method results in a gradually increasing contact area between the metal and hoses, leading to increased friction. Consequently, the insertion distance of the metal tube into the hose is usually short, and the assembly process is time-consuming and labor-intensive. Furthermore, when corrugated pipes are involved, they are prone to deformation under high thrust, making assembly impossible. Utility Model Content

[0004] This utility model provides an assembly fixture for metal pipes and rubber hoses, which aims to solve the problem of poor practicality caused by the inconvenience of assembling existing metal pipes (corrugated pipes) and rubber hoses.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an assembly fixture for metal pipes and rubber hoses, comprising:

[0006] A fixing assembly has a cylindrical cavity for placing a glue tube, the diameter of which is larger than the outer diameter of the glue tube; one end of the cylindrical cavity is provided with an annular barrier that abuts against one end of the glue tube.

[0007] The pusher sleeve is coaxially arranged with the cylindrical cavity and corresponds to the other end of the cylindrical cavity;

[0008] A drive assembly is installed on the push sleeve and is used to drive the push sleeve to extend into the cylindrical cavity and squeeze the other end of the rubber tube, so that the rubber tube is deformed to fit against the inner wall of the cylindrical cavity and the inner diameter is expanded.

[0009] In this process, after the inner diameter of the hose is increased, the metal tube is inserted into the hose through the annular barrier.

[0010] In one possible implementation, the fixing component includes:

[0011] The workbench has an installation surface;

[0012] The lower mold is fixedly mounted on the mounting platform, and has a lower contact surface at the top. The lower contact surface is provided with a first semi-circular groove that passes through both ends of the lower mold.

[0013] The upper mold is located above the lower mold and has an upper contact surface at its bottom end that corresponds to the lower contact surface. The upper contact surface is provided with a second semi-circular groove that passes through both ends of the upper mold. After the upper mold and the lower mold are aligned, the second semi-circular groove and the first semi-circular groove surround each other to form the cylindrical cavity.

[0014] An adjustment structure, fixed on the mounting platform, is used to drive the upper mold to detach from the lower mold, or to drive the upper mold to engage with the lower mold.

[0015] In one possible implementation, the lower contact surface is provided with a first receiving groove communicating with the first semi-circular groove; the upper contact surface is provided with a second receiving groove communicating with the second semi-circular groove; the first receiving groove and the second receiving groove are used to form a limiting cavity after the upper mold and the lower mold are aligned.

[0016] An annular baffle is provided in the limiting cavity, and the axis of the annular baffle is collinear with the axis of the cylindrical cavity. The annular baffle is the annular blocking part.

[0017] In one possible implementation, the drive component is fixed to the mounting surface.

[0018] In one possible implementation, the driving component includes:

[0019] A sliding block is provided for the fixed installation of the push sleeve, and has a through hole communicating with the push sleeve;

[0020] The first telescopic structure is used to drive the slide to move along the axis of the cylindrical cavity.

[0021] In one possible implementation, the driving component further includes:

[0022] The central positioning post is slidably disposed in the cavity of the jacking sleeve;

[0023] The second telescopic structure, connected to the central positioning post, is used to push the central positioning post into the hose before the push sleeve contacts the hose.

[0024] In one possible implementation, the diameter of the central positioning post is set to be equal to the inner diameter of the tubing.

[0025] In one possible implementation, the central positioning post and the jacking sleeve are in clearance fit.

[0026] In one possible implementation, the end of the central positioning post away from the second telescopic structure is tapered.

[0027] In this implementation, the cylindrical cavity provided by the fixing component ensures the placement of the hose and limits its position after axial compression and deformation. The pushing sleeve, driven by the drive component, moves closer to the annular barrier and pushes the hose, reducing manual labor while ensuring stability after the hose's inner diameter increases. This facilitates the insertion of metal tubes, including corrugated pipes, into the hose, enabling convenient assembly and high practicality. Attached Figure Description

[0036] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0037] Please refer to the following: Figure 1 and Figure 2The assembly fixture for metal pipes and rubber hoses provided by this utility model will now be described. The assembly fixture for metal pipes and rubber hoses includes a fixing component 10, a pushing sleeve 20, and a driving component 30. The fixing component 10 has a cylindrical cavity for placing the rubber hose, with a diameter larger than the outer diameter of the rubber hose. One end of the cylindrical cavity has an annular barrier portion for one end of the rubber hose to abut against. The pushing sleeve 20 is coaxially arranged with the cylindrical cavity and corresponds to the other end of the cylindrical cavity. The driving component 30 is used to install the pushing sleeve 20 and can drive the pushing sleeve 20 to extend into the cylindrical cavity and squeeze the other end of the rubber hose, causing the rubber hose to deform and fit against the inner wall of the cylindrical cavity, thus expanding its inner diameter.

[0038] Specifically, after the inner diameter of the hose is increased, the metal tube is inserted into the hose through the annular barrier.

[0039] The assembly fixture for metal tubes and hoses provided in this embodiment, compared with the prior art, ensures the placement of the hose through the cylindrical cavity provided by the fixing component 10, and also limits the hose after it is subjected to axial compression and deformation. The pusher sleeve 20, driven by the drive component 30, moves closer to the annular barrier and pushes the hose, reducing manual labor while ensuring stability after the hose's inner diameter increases. This facilitates the insertion of metal tubes, including corrugated pipes, into the hose, achieving convenient assembly and strong practicality.

[0040] In some embodiments, the fixing component 10 may be as follows: Figures 1 to 3 The structure shown. See also Figures 1 to 3 The fixing assembly 10 includes a worktable 11, a lower mold 12, an upper mold 13, and an adjustment structure 14. The worktable 11 has a mounting surface. The lower mold 12 is fixedly mounted on the mounting surface, with a lower contact surface at its top and a first semi-circular groove 15 penetrating both ends of the lower mold 12. The upper mold 13 is located above the lower mold 12, with an upper contact surface at its bottom corresponding to the lower contact surface, and a second semi-circular groove 16 penetrating both ends of the upper mold 13. After the upper mold 13 and the lower mold 12 are engaged, the second semi-circular groove 16 and the first semi-circular groove 15 enclose each other to form a cylindrical cavity. The adjustment structure 14 is fixedly mounted on the mounting surface and can either disengage the upper mold 13 from the lower mold 12 or engage the upper mold 13 with the lower mold 12.

[0041] After the upper mold 13 and the lower mold 12 are aligned, they form a cylindrical cavity, which facilitates the insertion of the tubing or the removal of the assembled tubing. At the same time, the upper mold 13 is controlled by the adjustment structure 14 to ensure the stability of the upper mold 13 when aligned with the lower mold 12.

[0042] In this embodiment, the adjusting structure 14 may include a boom 141 and a third telescopic structure 142. The boom 141 is fixed to the mounting platform, with its top end positioned above the upper mold 13. The third telescopic structure 142 is fixed to the boom 141, with its bottom end connected to the upper mold 13, thereby driving the upper mold 13 to move up and down. This structure enables the opening and closing of the upper mold 13 and the lower mold 12.

[0043] As another embodiment of the adjustment structure 14, see [link to relevant documentation]. Figure 1 The adjusting structure 14 may include a boom 141 and a third telescopic structure 142. The boom 141 is fixed to the mounting platform, with its top end positioned above the upper mold 13. The top end of the third telescopic structure 142 is rotatably connected to the boom 141, with its rotation axis aligned along the axis of the cylindrical cavity. Its bottom end is rotatably connected to the upper mold 13, with its rotation axis also aligned along the axis of the cylindrical cavity. In this configuration, the upper mold 13 can be rotatably connected to the boom 141 via a connecting arm 143, with the rotation direction aligned along the axis of the cylindrical cavity. The third telescopic structure 142 enables pitch and tilt control of the upper mold 13. This structure allows for the opening and closing of the upper mold 13 and the lower mold 12, while also ensuring the accuracy of their alignment.

[0044] The third telescopic structure 142 can be a hydraulic cylinder.

[0045] In some embodiments, the upper mold 13 and the lower mold 12 described above can be adopted as follows: Figure 3 The structure shown. See also Figure 3 The lower contact surface is provided with a first receiving groove that communicates with the first semi-circular groove 15. The upper contact surface is provided with a second receiving groove that communicates with the second semi-circular groove 16. The first receiving groove and the second receiving groove can be closed to form a limiting cavity after the upper mold 13 and the lower mold 12 are engaged.

[0046] An annular baffle 17 is provided in the limiting cavity. The axis of the annular baffle 17 is collinear with the axis of the cylindrical cavity. The annular baffle 17 is an annular blocking part.

[0047] The limiting groove formed by the first and second receiving grooves ensures the fixation of the annular baffle 17 while also ensuring its detachable connection. The annular baffle 17 can be a ring, and the diameter of its inner hole must be larger than the diameter of the metal tube and smaller than the outer diameter of the rubber tube.

[0048] In this embodiment, the first receiving groove can be a semi-circular groove with a diameter greater than that of the first semi-circular groove 15, and the second receiving groove can be a semi-circular groove with a diameter greater than that of the second semi-circular groove 16, and the first receiving groove and the second receiving groove have the same size.

[0049] In some embodiments, the driving component 30 described above may employ, for example... Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 The drive assembly 30 is fixed on the mounting platform to ensure stable operation of the drive assembly 30.

[0050] In some embodiments, the driving component 30 described above may employ, for example... Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 The drive assembly 30 includes a slide 31 and a first telescopic structure 32. The slide 31 is used for the fixed installation of the push sleeve 20 and has a through hole communicating with the push sleeve 20. The first telescopic structure 32 can drive the slide 31 to move in the axial direction of the cylindrical cavity.

[0051] The first telescopic structure 32 can drive the push sleeve 20 to move, thereby ensuring the compression of the hose.

[0052] A slide rail can be installed on the mounting platform, and the slide block 31 can be slidably connected to the slide rail. A fixing plate can be installed on the mounting platform for fixing the first telescopic structure 32. The first telescopic structure 32 drives the slide block 31 to move, thereby realizing the movement and adjustment of the push sleeve 20.

[0053] In this embodiment, two first telescopic structures 32 can be provided, with the two first telescopic structures 32 spaced apart, thereby increasing the pushing force. The first telescopic structure 32 can be a hydraulic cylinder.

[0054] As another embodiment of the drive assembly 30 and the push sleeve 20, the drive assembly 30 may be a hollow third telescopic structure 142, which is coaxially connected with the push sleeve 20.

[0055] In some embodiments, the driving component 30 described above may employ, for example... Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 The drive assembly 30 also includes a central positioning post 33 and a second telescopic structure 34. The central positioning post 33 is slidably disposed in the cavity of the push sleeve 20. The second telescopic structure 34 is connected to the central positioning post 33 and can push the central positioning post 33 into the hose before the push sleeve 20 contacts the hose.

[0056] Since the contact surface between the push sleeve 20 and the hose is an annular surface, after the push sleeve 20 squeezes the hose, the hose may be deformed into a flat shape or directly displaced due to the squeezing force. At this time, the central positioning post 33 can be inserted into the hose first to limit it inside the hose. Then the push sleeve 20 squeezes the hose to ensure that the hose can extend outward to increase the inner diameter.

[0057] The second telescopic structure 34 can be fixed on the mounting platform and located between the two first telescopic structures 32, and can be an electric cylinder.

[0058] In some embodiments, the aforementioned central positioning post 33 may be adopted as follows: Figure 4 The structure shown. See also Figure 4 The diameter of the central positioning post 33 is set to be equal to the inner diameter of the hose. This structure can ensure that the central positioning post 33 limits the hose and ensures the hose extension effect.

[0059] In some embodiments, the central positioning post 33 and the jacking sleeve 20 can be adopted as follows: Figure 3 and Figure 4 The structure shown. See also Figure 3 and Figure 4 The central positioning post 33 and the push sleeve 20 are in clearance fit. This structure can ensure the sliding of the central positioning post 33 relative to the push sleeve 20, and at the same time ensure the squeezing effect on the hose.

[0060] In some embodiments, the aforementioned central positioning post 33 may be adopted as follows: Figure 4 The structure shown. See also Figure 4 The end of the central positioning post 33 away from the second telescopic structure 34 is tapered, which ensures that the central positioning post 33 can be easily inserted into the tubing.

[0061] It should be noted that an annular beveled section can be provided at the extrusion end of the push sleeve 20 to further prevent the hose from shifting.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
