[0002] A microwave filter is a device used to separate microwave signals of different frequencies, and it has a wide range of applications in the fields of microwave communication, radar, electronic countermeasure, and microwave measuring instruments. Most current microwave filters have a rectangular appearance and interfaces are provided at the ends.

[0003] In the prior art, during the production and processing of microwave filters, various operations such as processing and detection are often required. For processing and detection operations, the microwave filter needs to be positioned to ensure its stability before processing and detection can be carried out. However, most of the existing microwave filter positioning jigs generally need to position the microwave filter separately from both sides or multiple sides, and need to be operated one by one, with a complex structure, which affects the efficiency and positioning accuracy.

[0004] Therefore, it is very necessary to propose a microwave filter positioning tooling to solve the above problems. Content of the Utility Model

Specific embodiments

[0024] To make the technical means, creative features, achieved purposes, and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As Figures 1-5 shown, a microwave filter positioning tooling includes a base 1 and a filter body 2. A clamping mechanism for positioning the filter body 2 is provided at the top of the base 1. The clamping mechanism includes fixed shells 5 symmetrically arranged at both ends of the top of the base 1. The fixed shell 5 is a hollow structure. A traction arm 12 is horizontally movably connected to the fixed shell 5. Side clamping plates 4 are symmetrically and fixedly arranged at the closer ends of the two traction arms 12. A lifting arm 9 is longitudinally movably connected to the fixed shell 5. The lower end of the lifting arm 9 extends to the bottom of the base 1. A second guide groove 15 is provided on the side wall of the upper end of the lifting arm 9, and the second guide groove 15 is inclined. The second guide grooves 15 are symmetrically arranged on both sides of the upper end of the lifting arm 9. A second through groove 13 is provided at the end of the traction arm 12 far from the side clamping plate 4. The upper end of the lifting arm 9 is movably connected to the inner side of the second through groove 13, and a slider 14 that is slidably and guidingly matched with the second guide groove 15 is fixedly arranged on the inner wall of the second through groove 13. The sliders 14 are symmetrically arranged on both sides of the inner cavity of the second through groove 13, and the inclination of the slider 14 is adapted to the inclination of the second guide groove 15;

[0026] A driving mechanism for driving the lifting of the lifting arm 9 is provided at the bottom of the base 1. The driving mechanism includes a cylinder 3 arranged at the bottom of the base 1. A lifting frame 8 driven by the cylinder 3 to lift is provided at the bottom of the base 1. Both ends of the lifting frame 8 are respectively connected to the lower ends of the two lifting arms 9.

[0027] To increase the stability of the traction arm 12, a roller 16 is rotatably connected to the inner side of the second through groove 13 near the side clamping plate 4. The side of the upper end of the lifting arm 9 near the side clamping plate 4 is an inclined surface, and the inclination of the inclined surface is adapted to the inclination of the second guide groove 15, and the roller 16 is used for rolling cooperation with this inclined surface.

[0028] Further, in order to simultaneously clamp the two ends of the filter body 2, the side clamping plates 4 are in a "concave" shape, and end clamping plates 10 are symmetrically and movably arranged at both ends of the side clamping plates 4. A convex shaft 17 is vertically arranged at the bottom of the end clamping plate 10. At the corresponding position of the top of the base 1 and the end clamping plate 10, a first guide groove 6 is opened, and the two first guide grooves 6 at the same end are in a "V" shape. The lower end of the convex shaft 17 is movably and guidingly connected to the inner side of the first guide groove 6. The first guide groove 6 is configured such that when the two side clamping plates 4 approach each other and displace, the two end clamping plates 10 on the same side clamping plate 4 approach each other and displace.

[0029] In order to increase the stability of the end clamping plate 10, guide rods 11 are arranged on the opposite sides of the two end clamping plates 10 on the same side clamping plate 4, and the guide rods 11 are movably and guidingly matched with the ends of the side clamping plates 4.

[0030] It should be noted that the present utility model is a microwave filter positioning tooling. When in use, the filter body 2 is generally placed in the space between the two side clamping plates 4 and the end clamping plates 10 at the top of the base 1, without precise placement. During positioning, the control cylinder 3 is driven to longitudinally displace the lifting arm 9. Under the action of the slider 14, the second guide groove 15, and the roller 16, the roller 16 transversely displaces. The roller 16 drives the side clamping plates 4 to clamp the two sides of the filter body 2. While the side clamping plates 4 displace, under the action of the convex shaft 17 and the first guide groove 6, the end clamping plates 10 displace to clamp the two ends of the filter body 2, thereby simultaneously realizing the positioning of the filter body 2 in four directions. The positioning is fast, the structure is simple, the operation is convenient, the efficiency is improved, and automatic centering can be achieved during positioning, improving the positioning accuracy.
