[0027] Example 1

[0028] Reference Figure 1-Figure 4The first embodiment of the present application provides an alignment device for connecting the ports of a composite pipe 30, comprising: a support plate 10, a drive assembly 20 and a clamping assembly 40. Two support members 11 are arranged on the support plate 10. The drive assembly 20 is arranged on the support plate 10, and the drive assembly 20 is used to drive the two support members 11 to move in a direction of approaching or moving away from each other. The two clamping assemblies 40 are symmetrically arranged on the two support members 11; wherein the clamping assembly 40 includes a positioning cylinder 41, a positioning rod 44, a guide ring 42 and a guide rod 43; the positioning cylinder 41 is used to be sleeved on the periphery of the pipe 30, the positioning cylinder 41 is connected to the support member 11, and a plurality of positioning rods 44 radially penetrate the positioning cylinder 41, the inner end of the positioning rod 44 is used to abut against the outer wall of the pipe 30, and each positioning rod 44 has a first inclined surface 61; the guide ring 42 is sleeved on the positioning cylinder 41 and can move along its axial direction, the guide rod 43 corresponds to the positioning rod 44 one by one, the guide rod 43 is connected to the guide ring 42, and each guide rod 43 has a second inclined surface 431, and the second inclined surface 431 is used to abut against the first inclined surface 61 and drive the positioning rod 44 to move in a direction close to the pipe 30.

[0029] In this embodiment, the support plate 10 provides an overall support force for the alignment device for connecting the ports of the composite pipe 30. At least three mounting holes can be reserved on the support plate 10. The support plate 10 is installed on the ceiling by screws penetrating the mounting holes. Two clamping assemblies 40 are arranged on the support plate 10. The two clamping assemblies 40 are located at the same height. The two clamping assemblies 40 have the same structure and are arranged in a symmetrical state. The two clamping assemblies 40 are used to clamp the port positions of the two composite pipes 30 respectively. The two clamping assemblies 40 are connected to the support plate 10 through a support member 11 respectively. The driving assembly 20 drives the two clamping assemblies 40 to move synchronously in the direction of approaching or moving away from each other, so that when the two clamping assemblies 40 are at a relatively far distance, it is convenient to install the ports of the two pipes 30, and the ports of the pipes 30 can be close to each other, so that the ports of the two pipes 30 can be close to each other, and can maintain a state of abutting each other, which is convenient for processing the ports of the two pipes 30. For ease of understanding, a single clamping assembly 40 is used as an example for explanation. The clamping of the pipe 30 is achieved through multiple positioning rods 44. All positioning rods 44 are distributed in a ring shape. The positioning rods 44 penetrate the side wall of the positioning cylinder 41 along the radial direction of the positioning cylinder 41. The inner ends of the positioning rods 44 are used to abut against the outer wall of the pipe 30. When the guide ring 42 moves along the axial direction of the positioning cylinder 41, all the guide rods 43 move laterally by the same distance. All the guide rods 43 have the same structure. The second inclined surface 431 of the guide rod 43 contacts the first inclined surface 61 of the positioning rod 44. During the continuous lateral movement of the guide rod 43, the second inclined surface 431 applies a component force along the radial direction of the positioning cylinder 41 to the first inclined surface 61, so that all the positioning rods 44 move inward synchronously to achieve the clamping of the pipe 30. It should be noted that the inner ends of all the positioning rods 44 are enclosed to form a circular accommodating space. In the initial state, the center of the circle is located on the axis of the positioning cylinder 41. When all the positioning rods 44 move inward synchronously for a certain distance, the center of the circle is always located on the axis of the positioning cylinder 41, ensuring that when the positioning rods 44 are driven to move by the guide ring 42 and the guide rod 43, the axis of the pipe 30 clamped by the positioning rod 44 coincides with the axis of the positioning cylinder 41, and then by making the axes of the positioning cylinders 41 of the two clamping units collinear, the axes of the clamped pipe 30 are also collinear.

[0030] Example 2

[0031] As an optional implementation, refer to Figure 1 and Figure 2The present embodiment provides a specific structure of a driving assembly 20, including: the driving assembly 20 includes a driving motor 24, a driving wheel 21, a rack 22 and a crossbeam 23; the driving motor 24 is arranged on the support plate 10, the driving wheel 21 is sleeved on the output shaft of the driving motor 24, the crossbeam 23 is arranged on the support plate 10, the crossbeam 23 and the support member 11 are connected by at least two connecting rods 12, the support plate 10 is provided with a through groove 13 for moving the connecting rod 12, the outer ends of the two racks 22 are respectively connected to the crossbeam 23, the inner ends of the two racks 22 are free ends, and the two racks 22 are respectively located on both sides of the driving wheel 21 and meshed with the driving wheel 21.

[0032] In this embodiment, the cross beam 23 and the support member 11 are connected by at least two connecting rods 12, which improves the stability of the connection between the cross beam 23 and the support member 11. By meshing the driving wheel 21 with the rack 22, the two clamping units can move synchronously, so as to drive the ports of the two pipes 30 to move.

[0033] Example 3

[0034] As an optional implementation, refer to Figure 3 and Figure 4 This embodiment provides a specific structure of a first inclined surface 61, including: a portion of the positioning rod 44 located outside the positioning cylinder 41 is provided with a through hole 441, and an inclined wedge block 60 is provided on the inner wall of the through hole 441 on one side close to the positioning cylinder 41, and the inclined wedge block 60 has a first inclined surface 61, and the first inclined surface 61 gradually inclines in the direction away from the positioning cylinder 41 toward the direction away from the guide ring 42.

[0035] In this embodiment, by providing a through hole 441 on the positioning rod 44, the guide rod 43 can pass through the through hole 441, and the through hole 441 plays a guiding and limiting role for the guide rod 43, ensuring that the second inclined surface 431 of the guide rod 43 can contact the first inclined surface 61. Figure 4The first inclined surface 61 is inclined rightward from bottom to top, and the upper end of the first inclined surface 61 is a horizontal placement surface. A guide hole is provided through the positioning cylinder 41, and the guide hole is used for the guide rod 43 to pass through. The guide hole and the guide rod 43 are in clearance fit. When the guide rod 43 moves rightward to the second inclined surface 431 and contacts the first inclined surface 61, the second inclined surface 431 applies a vertical downward thrust to the first inclined surface 61 (the guide rod 43 in the figure is located above the positioning cylinder 41; when the guide rod 43 is located below the positioning cylinder 41, its thrust is upward; similarly, when the guide rod 43 is located on the left side of the positioning cylinder 41, its thrust is rightward), so that all the guide rods 43 move inward a certain distance to achieve tight contact with the pipe 30. In particular, when the positioning rod 44 moves inward to a distance equal to the projection distance of the second inclined surface 431 in the vertical direction, the lower end surface of the guide rod 43 contacts the placement surface at the upper end of the first inclined surface 61.

[0036] Example 4

[0037] As an optional implementation, refer to Figure 3 and Figure 4 This embodiment provides a specific structure of a second inclined surface 431, including: a plurality of second inclined surfaces 431 are provided at the free end of the guide rod 43, all the second inclined surfaces 431 are parallel to each other, and adjacent second inclined surfaces 431 are connected by a horizontal step surface 432.

[0038] In this embodiment, by setting a plurality of second inclined surfaces 431, it is possible to automatically adapt according to the different outer diameters of pipes 30 of different specifications, that is, when the outer diameter of the pipe 30 is smaller, the second inclined surface 431 located lower contacts the first inclined surface 61, and the step surface 432 on the guide rod 43 can contact the placement surface on the inclined wedge block 60. Through the contact between the planes, the contact stability is improved, that is, the stability of the guide rod 43 and the positioning rod 44 is improved.

[0039] Example 5

[0040] As an optional implementation, refer to Figure 1 and Figure 3 This embodiment provides a driving structure of a guide ring 42, including: a driving ring 50 is sleeved on the positioning cylinder 41, the driving ring 50 is threadedly matched with the positioning cylinder 41, and a side wall of the driving ring 50 close to the guide ring 42 is provided with an annular flange 51, and the annular flange 51 is used for abutting the guide ring 42.

[0041] Optionally, a limiting ring 70 is further sleeved on the positioning tube 41 . The limiting ring 70 is threadedly matched with the positioning tube 41 . The limiting ring 70 is located on the other side of the positioning rod 44 relative to the guide ring 42 . The limiting ring 70 is used to block the guide rod 43 .

[0042] In this embodiment, the drive ring 50 is threadedly matched with the positioning cylinder 41, and the drive ring 50 is rotated to move rightward on the positioning cylinder 41, thereby pushing the guide ring 42 to move rightward. An annular flange 51 is provided on the outer wall of the drive ring 50 to reduce the contact area between the drive ring 50 and the guide ring 42, thereby reducing the friction between the drive ring 50 and the guide ring 42. The position fixing of the guide ring 42 and the guide rod 43 is achieved by the limit ring 70 cooperating with the drive ring 50, so as to prevent the guide ring 42 from moving left and right at will.

[0043] Example 6

[0044] As an optional implementation, refer to Figure 1 and Figure 3 This embodiment provides a specific structure of a guide ring 42 , including: the outer wall of the positioning tube 41 is provided with a slide groove 422 extending along its axial direction, and the inner wall of the guide ring 42 is provided with a slider 421 for cooperating with the slide groove 422 .

[0045] Optionally, a compression spring 423 is disposed on the outer sleeve of the positioning cylinder 41 , and the compression spring 423 is located between the guide ring 42 and the positioning rod 44 .

[0046] In this embodiment, by providing a slider 421 on the guide ring 42, providing a slide groove 422 on the outer wall of the positioning tube 41, the slide groove 422 extends along the axial direction of the positioning tube 41, and the slider 421 is located in the slide groove 422, which plays a role of limiting and guiding the lateral movement of the guide ring 42, preventing the guide ring 42 from moving arbitrarily in the circumferential direction, and ensuring that the second inclined surface 431 on the guide rod 43 can contact the first inclined surface 61. By providing a compression spring 423, when the guide ring 42 loses the thrust of the drive ring 50, the guide ring 42 can move to the left under the action of the compression spring 423, so that the second inclined surface 431 automatically separates from the first inclined surface 61.

[0047] Example 7

[0048] As an optional implementation, refer to Figure 1 and Figure 3 This embodiment provides a specific structure of a guide rod 43, including: a gasket 443 is provided at one end of the positioning rod 44 for abutting against the pipe 30, and the gasket 443 is made of a flexible material.

[0049] Optionally, a return spring 442 is sleeved on the positioning rod 44 , and the return spring 442 is located between the gasket 443 and the inner wall of the positioning tube 41 .

[0050] In this embodiment, the gasket 443 can be made of rubber, so that the end of the positioning rod 44 can be in flexible contact with the pipe 30, so as to prevent the end of the positioning rod 44 from scratching the outer wall of the pipe 30. The return spring 442 is located between the gasket 443 and the inner wall of the positioning tube 41. When the guide ring 42 moves to the right, all the positioning rods 44 move inward. At this time, the return spring 442 is pulled. When the positioning rod 44 loses the external force of the guide rod 43, the positioning rod 44 can automatically move outward under the action of the return spring 442, increasing the circle formed by the inner ends of all the positioning rods 44, so as to facilitate the placement of the pipe 30 into the middle of the circle formed by the inner ends of all the positioning rods 44.
