Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of positioning tooling technology, and more specifically, to a positioning tooling for splicing the reflector surface of a steel structure antenna. Background Technology

[0002] Antenna reflector is a conductive curved or flat surface in a surface antenna used to concentrate and reflect electromagnetic waves emitted from the feed source in a certain direction to enhance the transmission effect. For medium-sized antenna reflectors, their size often reaches tens or even hundreds of meters, far exceeding the maximum processing range of existing machine tools, molds and other processing equipment. The overall processing is too difficult and not easy to transport, so they often need to be spliced ​​together.

[0003] Existing antennas often use threaded connections for segmented splicing, which has several drawbacks in actual use, such as slow connection speed, poor positioning accuracy, low connection strength, and poor splicing strength. In response to these shortcomings, some other types of locking fasteners have emerged on the market. However, these fasteners are inconvenient for positioning and installation of circular spliced ​​reflective surfaces, have a large blind spot, and have low positioning accuracy. Therefore, splicing and positioning devices are needed to assist in the work. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a positioning fixture for splicing steel structure antenna reflectors, which solves the technical problem that the manual alignment method in the prior art requires a high level of skill from the operating team and may result in errors.

[0005] According to one aspect, at least one embodiment of this disclosure provides a positioning fixture for splicing steel structure antenna reflectors, applied to a reflector body. The reflector body includes a center surface and multiple arc-shaped surfaces, all of which are detachably mounted on the center surface. A connecting plate is fixedly mounted on the arc-shaped surface. The fixture also includes a mounting frame, a rotating seat, a snap-fit ​​mechanism, and a fixing component. One end of the mounting frame is coaxially fixedly connected to the center surface. The rotating seat is rotatably mounted on the mounting frame via a rotating mechanism. A moving slot is provided on the rotating seat. The snap-fit ​​mechanism is movably mounted in the moving slot via a driving component for fixing the arc-shaped surfaces and cooperating with the driving component to bring the arc-shaped surfaces into contact with the center surface. The fixing component is mounted on the arc-shaped surface for fixing the arc-shaped surfaces and the center surface.

[0006] Preferably, the rotating mechanism includes a rotating shaft, rotating plates, and a locking assembly. The rotating shaft is rotatably disposed within the mounting frame, with one end of the rotating shaft passing through the mounting frame. Two rotating plates are symmetrically disposed on the rotating base, with one end of each rotating plate fixedly connected to the rotating shaft. The mounting frame has arc-shaped slots that mate with the rotating plates. The locking assembly is disposed on the rotating shaft and the mounting frame for fixing the rotating shaft.

[0007] Furthermore, the locking assembly includes a fixing plate, a first bolt, and threaded holes. The fixing plate is fixedly connected to one end of the rotating shaft. Both the fixing plate and the mounting bracket are threadedly engaged with the first bolt. The mounting bracket has multiple threaded holes that engage with the first bolt, and the first bolt is threadedly engaged with the inner wall of the threaded holes.

[0008] Furthermore, the locking mechanism includes a movable seat, an insert plate, a connecting rod, a spring, and a slot. The movable seat is slidably disposed within the movable groove. The movable seat has a through groove that mates with the connecting plate. A sliding groove is formed inside the movable seat. The insert plate slidably engages with the inner wall of the sliding groove. A through hole that mates with the insert plate is formed on the connecting plate. One end of the connecting rod passes through the movable seat and is fixedly connected to one end of the insert plate. The spring is sleeved on the outside of the connecting rod. Both ends of the spring are fixedly connected to one end of the insert plate and the inner wall of the sliding groove, respectively. The movable seat has the slot that mates with the insert plate.

[0009] As a further embodiment of this application, the drive assembly includes a threaded rod and a drive motor. The threaded rod is rotatably disposed in the movable groove and is threadedly engaged with the movable seat. The drive motor is mounted on the rotating seat, and the output end of the drive motor is coaxially and fixedly connected to one end of the threaded rod.

[0010] As a further embodiment of this application, the fixing component includes a protruding plate, a mating plate, and a second bolt. The protruding plate is fixedly connected to one end of the arc-shaped surface, and one end of the mating plate is fixedly connected to one end of the protruding plate. A snap-fit ​​groove that mates with the mating plate is provided on the center surface. The center surface, the mating plate, and the protruding plate are all threadedly engaged with the second bolt.

[0011] Based on the aforementioned solution, in order to assist in abutting and supporting the rotating seat after it rotates, the mounting frame is provided with an abutment groove that cooperates with the rotating seat.

[0012] Furthermore, in order to allow the connecting plate to move out of the through groove during the rotation of the movable seat, the connecting plate is L-shaped, one end of the connecting plate is set as an arc-shaped end face, and the inner wall of the through groove is also arc-shaped and matches the connecting plate.

[0013] The beneficial effects of the embodiments disclosed herein are as follows:

[0014] 1. In this disclosure, through the cooperation of the mounting bracket, rotating seat, rotating mechanism and snap-fit ​​mechanism, the connecting rod is pulled to move the insert plate into the slide groove, and then one end of the connecting plate on the arc surface is inserted into the through groove. After that, the connecting rod is released, and the insert plate passes through the through hole under the push of the spring, so that one end of the insert plate is inserted into the slot. In this way, the arc surface is fixed on the moving seat. The drive motor is started to move the arc surface toward the center surface and insert the docking plate into the snap-fit ​​groove, thus completing the docking and effectively improving the docking accuracy.

[0015] 2. In this disclosure, after the arc surface is joined, the connecting rod is pulled and the first bolt is tightened and removed. Then, the rotating seat is rotated so that the connecting plate on the fixed arc surface is moved out of the through groove. Finally, the second bolt is used to fix the arc surface and the center surface. This completes the joining and fixing of one arc surface. After the rotating seat is rotated, the joining of the next arc surface can be carried out. This joining and fixing of the arc surface and the center surface is convenient for operation and facilitates the positioning and joining of the next arc surface. Attached Figure Description

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-7 As shown, it illustrates a positioning fixture for splicing steel structure antenna reflectors in one embodiment of the present disclosure. It is applied to reflector body 1, which includes a center surface 2 and multiple arc surfaces 3. The multiple arc surfaces 3 are detachably mounted on the center surface 2. The fixture is used for positioning and assembling the multiple arc surfaces 3 with the center surface 2. A connecting plate 4 is fixedly mounted on the arc surface 3. It also includes a mounting bracket, a rotating seat 7, a snap-fit ​​mechanism, and a fixing component.

[0032] like Figure 1 , Figure 2 and Figure 6As shown, one end of the mounting bracket is coaxially fixedly connected to the center surface 2. The mounting bracket includes a base 5 and an L-shaped frame 6. One end of the L-shaped frame 6 is fixedly connected to the center surface 2. A rotating seat 7 is rotatably mounted on the mounting bracket via a rotating mechanism. The rotating seat 7 has a moving groove 8. The rotating mechanism includes a rotating shaft 9, a rotating plate 10, and a locking assembly. The rotating shaft 9 is rotatably mounted inside the mounting bracket, with one end of the rotating shaft 9 passing through the mounting bracket. Two rotating plates 10 are symmetrically arranged on the rotating seat 7, and one end of each rotating plate 10 is fixedly connected to the rotating shaft 9. The mounting bracket has an arc-shaped slot 11 that cooperates with the rotating plate 10. By rotating the rotating seat 7, the rotating seat 7 rotates around the axis of the rotating shaft 9 under the support of the two rotating plates 10. The locking assembly is set on the rotating shaft 9 and the mounting bracket to fix the rotating shaft 9. The fixed assembly includes a fixed plate 12, a first bolt 13, and threaded holes 14. The fixed plate 12 is fixedly connected to one end of the rotating shaft 9. Both the fixed plate 12 and the mounting bracket are threadedly engaged with the first bolt 13. The mounting bracket has multiple threaded holes 14 that engage with the first bolt 13. The multiple threaded holes 14 are circumferentially distributed and correspond to the number of arc surfaces 3. For example, if there are three arc surfaces 3, then there are also three threaded holes 14. With the axis of the rotating shaft 9 as the center, the included angle between adjacent threaded holes 14 is 60 degrees. The first bolt 13 is threadedly engaged with the inner wall of the threaded hole 14. After rotating the rotating seat 7, the through hole on the fixed plate 12 is connected to the corresponding threaded hole 14. The fixed plate 12 and the mounting bracket are fixed with bolts, thus fixing the rotating seat 7.

[0033] In order to assist in abutting and supporting the rotating seat 7 after it rotates, the mounting frame is provided with an abutment groove 28 that matches the rotating seat 7. It should be added that the L-shaped frame 6 is provided with an arc-shaped part that matches the rotation trajectory of the rotating seat 7 to avoid collision between the rotating seat 7 and the L-shaped frame.

[0034] like Figure 4 and Figure 5As shown, the snap-fit ​​mechanism is movably mounted in the moving groove 8 via a drive assembly. It is used to fix the arc-shaped surface 3 and does not cooperate with the drive assembly to align the arc-shaped surface 3 with the center surface 2. The snap-fit ​​mechanism includes a moving base 15, an insert plate 17, a connecting rod 20, a spring 21, and a slot 22. The moving base 15 is slidably mounted in the moving groove 8. The moving base 15 has a through groove 16 that mates with the connecting plate 4. To allow the connecting plate 4 to move out of the through groove 16 during the rotation of the moving base 15, the connecting plate 4 is L-shaped, with one end having an arc-shaped end face. The inner wall of the through groove 16 is also arc-shaped and mates with the connecting plate 4. A sliding groove 18 is provided inside the moving base 15, and the insert plate 17 slides against the inner wall of the sliding groove 18. A through hole 19 is provided on the connecting plate 4 that mates with the insert plate 17. The connecting rod 20... One end of the connecting rod 20 passes through the movable seat 15 and is fixedly connected to one end of the insert plate 17. The spring 21 is sleeved on the outside of the connecting rod 20. The two ends of the spring 21 are fixedly connected to one end of the insert plate 17 and the inner side wall of the slide groove 18, respectively. The movable seat 15 has a slot 22 that cooperates with the insert plate 17. By pulling the connecting rod 20, the connecting rod 20 drives the insert plate 17 to move into the slide groove 18. The insert plate 17 squeezes the spring 21, and the spring 21 contracts and generates elastic force. Then, one end of the connecting plate 4 on the arc surface 3 is inserted into the through groove 16, and the through hole 19, the slot 22 and the slide groove 18 are all connected. After that, the connecting rod 20 is released, and the insert plate 17 passes through the through hole 19 under the push of the spring 21, so that one end of the insert plate 17 is inserted into the slot 22. In this way, the arc surface 3 is fixed on the movable seat 15.

[0035] like Figure 2 As shown, the drive assembly includes a threaded rod 23 and a drive motor 24. The threaded rod 23 is rotatably mounted in the moving groove 8 and is parallel to the moving groove 8. A telescopic protective sleeve is fitted on the threaded rod 23 for protection to prevent dust and impurities from adhering to the threaded rod 23. The threaded rod 23 is threadedly engaged with the moving seat 15. The drive motor 24 is mounted on the rotating seat 7. The output end of the drive motor 24 is coaxially and fixedly connected to one end of the threaded rod 23. By starting the drive motor 24, the output end of the drive motor 24 rotates, causing the threaded rod 23 to rotate. The threaded rod 23 causes the moving seat 15 to move along the inner wall of the moving groove 8 toward the center surface 2. The moving seat 15 causes the arc-shaped surface 3 to move toward the center surface 2 and complete the docking.

[0036] like Figure 7As shown, the fixing component is set on the arc surface 3 to fix the arc surface 3 and the center surface 2. The fixing component includes a protruding plate 25, a mating plate 26 and a second bolt 27. The protruding plate 25 is fixedly connected to one end of the arc surface 3, and one end of the mating plate 26 is fixedly connected to one end of the protruding plate 25. The center surface 2 is provided with a snap-fit ​​groove 29 that mates with the mating plate. The center surface 2, the mating plate 26 and the protruding plate 25 are all threadedly engaged with the second bolt 27. The drive motor 24 drives the arc surface 3 to move toward the center surface 2. The arc surface drives the protruding plate 25 and the mating plate 26 to move. Then the mating plate 26 is inserted into the snap-fit ​​groove 29 to complete the docking of the center surface 2 and the arc surface 3. It should be added that after the docking of one arc surface 3 is completed, the connecting rod 20 is pulled and the first bolt 13 is turned and removed. Then the rotating seat 7 is rotated so that the connecting plate 4 on the fixed arc surface 3 moves out of the through groove 16. Finally, the second bolt 27 is used to fix the arc surface 3 and the center surface 2.

[0037] It should be added that the fixing component is inclinedly set at the edge of the arc surface 3. When the arc surface 3 drives the protruding plate 25 to move under the drive of the drive motor 24, the protruding plate 25 does not contact the rotating seat 7 and the mounting bracket.

[0038] Working principle: When assembling multiple arc-shaped surfaces 3 and the center surface 2, the positioning fixture for splicing the reflector surface of the steel structure antenna pre-rotates and fixes the rotating seat 7 to the side where the "opening" of the through slot 16 faces. By pulling the connecting rod 20, the connecting rod 20 moves the insert plate 17 into the slide groove 18. The insert plate 17 compresses the spring 21, and the spring 21 contracts and generates elastic force. Then, one end of the connecting plate 4 on the arc-shaped surface 3 is inserted into the through slot 16, connecting the through hole 19, the slot 22, and the slide groove 18. After that, the connecting rod 20 is released, and the insert plate 17, pushed by the spring 21, passes through the through hole 19 and one end of the insert plate 17 is inserted into the slot 22. This fixes the arc-shaped surface 3 on the moving seat 15. The drive motor 24 is then started. The output end of the motor 24 rotates, driving the threaded rod 23 to rotate. The threaded rod 23 drives the movable seat 15 to move along the inner wall of the movable groove 8 toward the center surface 2. The movable seat 15 drives the arc surface 3 to move toward the center surface 2 and complete the docking. Then, the docking plate 26 is inserted into the snap-fit ​​groove 29 to complete the docking of the center surface 2 and the arc surface 3. After the docking of the arc surface 3 is completed, the connecting rod 20 is pulled and the first bolt 13 is tightened and removed. Then, the rotating seat 7 is rotated, so that the connecting plate 4 on the fixed arc surface 3 moves out of the through groove 16. Finally, the second bolt 27 is used to fix the arc surface 3 and the center surface 2. This completes the docking and fixing of one arc surface 3. After the rotating seat 7 rotates, the docking of the next arc surface 3 can be carried out, which facilitates operation.
