Specific embodiments

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The following further describes the present utility model with reference to the embodiments.

[0025] Embodiment: Refer to the attached Figure 1 — attached Figure 5 As shown, a fixing tool for U-shaped waveguide processing includes a fixed seat 1. Above the fixed seat 1, any device that can suspend it can be connected. Below the fixed seat 1, an inner support assembly for maintaining the distance between the two ends of the U-shaped waveguide rod is provided. A connecting pipe 102 is fixedly installed on the fixed seat 1, and an air injection tank is fixedly installed on the fixed seat 1. The air injection tank is communicated with the connecting pipe 102. The inner support assembly includes two groups of telescopic rods 3 symmetrically installed on both sides of the connecting pipe 102. The extended telescopic rods 3 can push the pushing block 301 close to the U-shaped waveguide rod, so as to ensure that the two ends of the U-shaped waveguide rod will not deform during the process of fixing the U-shaped waveguide rod. The end of the telescopic rod 3 is fixedly installed with a pushing block 301, and the pushing block 301 supports the end of the U-shaped waveguide rod. The pushing block 301 is made of a memory elastic material and can expand and then recover.

[0026] Specifically, the extended telescopic rod 3 pushes the pushing block 301 close to the U-shaped waveguide rod. When the pushing block 301 is close to the U-shaped waveguide rod, the air injection tank injects air into the telescopic rod 3 through the connecting pipe 102, and the gas flows to the pushing block 301 to make it expand. The expanded pushing block 301 can fit and fix the U-shaped waveguide rod more closely, maintaining the distance between the two ends of the U-shaped waveguide rod.

[0027] Further, a connecting block 302 is fixedly installed on the telescopic rod 3. The connecting block 302 is used to support the sliding and pushing of the guide frame 405. The same group of guide frames 405 are slidably inserted on the two groups of connecting blocks 302. The cross-section of the guide frame 405 is an equilateral triangle. By pushing the guide frame 405, the two groups of telescopic rods 3 are controlled to move outward simultaneously to support the U-shaped waveguide rod.

[0028] Furthermore, a support frame 2 is arranged at the bottom of the fixed seat 1. An electric push rod 4 is fixedly installed at the center of the support frame 2. The electric push rod 4 is used to control the inner support assembly and the two groups of clamping blocks 204 to move simultaneously to fix the U-shaped waveguide rod. A connecting rod c403 is fixedly installed at the end of the electric push rod 4. There is a height difference between the guide push rod 404 and the electric push rod 4. The connecting rod c403 is used to connect the electric push rod 4 and the guide push rod 404. The guide push rod 404 is fixedly connected to the connecting rod c403, and the guide push rod 404 is fixedly connected to the guide frame 405. The guide push rod 404 is used to push the guide frame 405 to move.

[0029] Place the end of the U-shaped waveguide rod outside the push block 301, and let the electric push rod 4 pull in the direction away from the U-shaped waveguide rod. The connecting rod c403 on the electric push rod 4 pulls the guide frame 405 through the guide push rod 404. The guide frame 405 pushes the two groups of telescopic rods 3 to extend outward through the connecting block 302, so that the push block 301 cooperates with the clamping block 204 to clamp the end of the U-shaped waveguide rod.

[0030] To prevent the inner support assembly from over-pushing the end of the U-shaped waveguide rod outward, resulting in the outward expansion of the end of the U-shaped waveguide rod, two groups of support rods 101 are fixedly connected between the fixed seat 1 and the support frame 2. A clamping assembly is arranged on the support frame 2. The clamping assembly clamps and fixes from the outside of the U-shaped waveguide rod. The clamping assembly includes a connecting shaft a201 rotatably installed on the support frame 2. By setting the connecting shaft a201, the connecting rod a guide rod 202 can rotate while being connected to the support frame 2. A connecting rod a guide rod 202 is fixedly installed on the connecting shaft a201. The connecting rod a guide rod 202 is used to connect the support frame 2 and the clamping block 204. A connecting shaft b203 is fixed at the end of the connecting rod a guide rod 202. The connecting shaft b203 is used to connect the connecting rod a guide rod 202 and the clamping block 204. A clamping block 204 is rotatably installed on the connecting shaft b203. A rubber pad is fixedly installed on the side of the clamping block 204 close to the push block 301. Anti-slip lines are provided on the rubber pad. By controlling the two groups of clamping blocks 204 to move towards each other, the U-shaped waveguide rod can be clamped and fixed.

[0031] Specifically, a rotating shaft a205 is rotatably installed on the support frame 2. By setting the rotating shaft a205, the control rod 206 can rotate while being connected to the support frame 2. The control rod 206 is fixedly installed on the rotating shaft a205. The control rod 206 is used to drive the movement of the clamping block 204. A rotating shaft b207 is fixedly installed at the end of the control rod 206, and the rotating shaft b207 is rotatably connected to the clamping block 204. By setting the rotating shaft b207, the clamping block 204 can rotate relative to the control rod 206, so as to more easily fit the surface of the U-shaped waveguide rod and strengthen the clamping and fixing of it. A connecting rod b208 is fixedly installed on the control rod 206. The connecting rod b208 is used to connect the control rod 206 and the positioning shaft 401.

[0032] Furthermore, a positioning shaft 401 is fixedly installed on the electric push rod 4. Connecting handles 402 are rotatably installed at both ends of the positioning shaft 401. The two groups of connecting handles 402 are respectively rotatably connected to the two groups of connecting rods b208. By setting the connecting handles 402, during the forward and backward movement of the electric push rod 4, the connecting handles 402 rotate and push the control rod 206 to rotate together, thereby controlling the clamping block 204 to clamp the U-shaped waveguide rod.

[0033] Working principle: Place the end of the U-shaped waveguide rod between the clamping block 204 and the push block 301. Let the electric push rod 4 pull in the direction away from the U-shaped waveguide rod. The two groups of positioning shafts 401 on the electric push rod 4 move accordingly, and the control rod 206 is pulled by the connecting handle 402 to move towards the central axis of the electric push rod 4. As a result, the clamping block 204 on the control rod 206 moves towards the inner support assembly. At the same time, the connecting rod c403 on the electric push rod 4 pulls the guide push rod 404 through the guide rod 404, and the guide frame 405 pushes the two groups of telescopic rods 3 to extend outwards through the connecting block 302, so that the push block 301 cooperates with the clamping block 204 to clamp the end of the U-shaped waveguide rod.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
