Abstract
Description
Technical Field
[0001] This utility model relates to a positioning and splicing fixture for an E-bend waveguide, belonging to the field of bend waveguide manufacturing technology. Background Technology
[0002] Due to structural and transmission requirements, waveguide transmission lines are typically composed of straight waveguides of varying lengths, H-bend waveguides of varying angles and lengths, and E-bend waveguides. To accommodate adjustments during assembly, a flexible waveguide or extension waveguide section is sometimes added. H-bend and E-bend waveguides are generally fabricated from straight waveguides and then spliced together. The angle and perpendicularity of this splicing play a crucial role in the energy transmission direction. For example, an E-bend waveguide is formed by splicing two straight waveguides with beveled surfaces. Therefore, the splicing angle is particularly important in E-bend waveguides; the perpendicularity generally needs to be accurate to two decimal places. Traditional E-bend waveguides are formed by welding or gluing. Manual welding or gluing results in inconsistent quality, is prone to misalignment, and has low strength at the splice joints. Manually welded products are easily deformed or even cracked during assembly, and the quality is even worse after secondary welding. Utility Model Content

[0025] The utility model will be explained in detail below in combination with the drawings and specific embodiments.
[0026] Embodiment one
[0027] As shown in the figure, the upper part is the front view of the E-bend waveguide positioning and splicing tool in the embodiment, and the lower part is the top view. As shown in the figure, the E-bend waveguide positioning and splicing tool comprises two pressing plates 2, and the two pressing plates 2 are used for clamping the E-bend waveguide. Figure 1 The E-bend waveguide is symmetrically spliced by two waveguide units 1. As shown in the figure, the waveguide unit 1 is processed from a straight waveguide, and the straight waveguide is cut at one end to form a splicing surface 11 at an angle of 45°, and the splicing surface 11 is cut perpendicularly to form an inclined surface 12.
[0028] Figure 2 The pressing plate 2 comprises two branch plates which are arranged perpendicularly to each other, and the two branch plates are each provided with a recess 21 on one side surface. As shown in the figure, the width of the recess 21 matches the width of the waveguide unit 1, and the waveguide unit 1 can be embedded in the recess 21.
[0029] The two waveguide units 1 are respectively embedded in the two recesses 21 of one pressing plate 2, the positions of the two waveguide units 1 are adjusted so that the splicing surfaces 11 of the splicing ends of the two waveguide units 1 are butted, then the other pressing plate 2 is connected with the two waveguide units 1 from the other side of the two waveguide units 1, the other side of the two waveguide units 1 is embedded in the pressing plate 2, and finally the two pressing plates 2 are connected by using the bolt 3, so that the two waveguide units 1 are clamped between the two pressing plates 2, the splicing surfaces 11 of the two waveguide units 1 are kept in the butted state, the subsequent welding or gluing is facilitated, and dislocation does not occur. Figure 3 Figure 4 In the embodiment, the setting direction of the branch plate is perpendicular to the setting direction of the corresponding waveguide unit 1, so that the setting directions of the two waveguide units 1 are perpendicular to each other. Figure 5
[0030]
[0031] In this embodiment, each branch plate of the pressure plate 2 has a connecting hole 22 on both sides corresponding to the groove 21, for a total of four connecting holes 22. The connecting holes 22 on the two pressure plates 2 are correspondingly provided, and the two pressure plates 2 are connected by four bolts 3 set in the connecting holes 22. On the opposite side of the two pressure plates 2, there is a countersunk groove at the corresponding connecting hole 22 for setting the bolts 3. When the two waveguide units 1 are connected to the first pressure plate 2, the bolts can be first set in the connecting hole 22 of the pressure plate 2. The bolt head is located in the countersunk groove, which allows the pressure plate 2 to fit against the workbench surface and prevents it from tilting due to the bolt head, making operation convenient.
[0032] Example 2
[0033] The positioning and splicing fixture in this embodiment is basically the same as that in Embodiment 1, except that it further includes a positioning plate 4, such as... Figure 6 As shown, the upper part is the front view of the E-bend waveguide positioning and splicing fixture in this embodiment, and the lower part is the top view. The positioning plate 4 has connecting parts at both ends that connect to two branch plates of a pressure plate 2, and positioning parts 41 for positioning two waveguide units 1. The connecting parts have positioning grooves 42 that match the ends of the branch plates. The ends of the branch plates are connected to the connecting parts by embedding the positioning grooves 42. Figure 7 As shown; the positioning plate 4 also includes a support platform 43, the positioning part 41 is higher than the support platform 43, and the side of the positioning part 41 facing the support platform 43 forms a positioning surface.
[0034] Combination Figure 8 As shown, a pressure plate 2 is connected to a positioning plate 4 and placed on a workbench. The bottom surface of the groove 21 is at the same height as the top surface of the support platform 43, so that the bottom surface of the groove 21 and the top surface of the support platform 43 are on the same plane. This ensures that the waveguide unit 1 will not tilt when placed on the groove 21 and the support platform 43. A bolt is installed in the connecting hole 22 of the pressure plate 2. Then, two waveguide units 1 are respectively embedded into the groove 21 of the pressure plate 2. The ends of the two waveguide units 1 away from the pressure plate 2 are supported on the top surface of the support platform 43. The waveguide units 1 are pushed so that the inclined surface 12 of one end abuts against the positioning surface of the positioning part 41. The two inclined surfaces 12 are in the same plane, so the splicing surfaces 11 of the two waveguide units 1 are spliced together, ensuring the splicing accuracy of the two waveguide units 1. Then, another pressure plate 2 is connected to clamp the two waveguide units 1.
