Description

Technical Field

[0001] This invention relates to the field of electromagnetic wave communication technology, and in particular to a waveguide flange mating clamping fixture. Background Technology

[0002] A waveguide is a specialized medium for transmitting microwave signals. It consists of a rectangular metal tube and a flange. The rectangular flange is welded to the metal tube, with the metal tube perpendicular to and centered on the flange face. The cross-sectional area of ​​the rectangular waveguide and the size of the flange face vary depending on the frequency band. Due to its low insertion loss and excellent standing wave performance, waveguides are widely used in the electromagnetic communication industry. In practical applications, multiple waveguide flanges are often connected together to achieve electromagnetic wave transmission through their coordinated operation.

[0003] Currently, most waveguide flange mating solutions involve using pins to position the flanges of the two waveguide flanges to be mated, and then using screws to fix the flanges together. However, it is worth noting that this waveguide flange mating solution has problems such as complicated operation and inconvenient tightening. Waveguide flange mating parts are easy to fall off or be lost during the process, it is inconvenient to use fastening tools to tighten the screws in confined spaces, and the efficiency of mating waveguide flanges in this way is relatively low, making it unsuitable for applications where waveguides are used extensively. On the other hand, some waveguide flanges are clamped together using dovetail clamps. Although this method is simple, it is easy to loosen and the clamping force cannot be controlled, making it less adaptable. Meanwhile, the above two methods of connecting waveguide flanges usually cannot intuitively read the pressure on the waveguide flange, nor can they accurately adjust the magnitude of the clamping force, which has certain limitations in practical use.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0025] Example 1 Please refer to Figure 1-12The system includes a waveguide flange 101 and a waveguide flange 202. Several clamping assemblies are provided on the outer side of the mating joint between waveguide flange 101 and waveguide flange 202. Each clamping assembly includes a mounting housing 201. A pair of clamping members 202 are rotatably connected to the top and bottom of the mounting housing 201. Each clamping member 202 has a hand-held portion 210 at its tail. A first connecting ear 204 and a second connecting ear 205 are respectively provided at both ends of the clamping member 202 near the mounting housing 201. A connecting rod 203 is rotatably connected to the inner side of the first connecting ear 204 and the second connecting ear 205, and located inside the mounting housing 201. A torque assembly is provided on the outer side of the connecting rod 203 to provide a force to bring the corresponding clamping member 202 closer to the other clamping member 202. A clamping force adjustment assembly is provided on the outer side of the connecting rod 203, and a clamping force reading assembly is provided at the end of the connecting rod 203 near the second connecting ear 205. The clamping member 202 is equipped with... The positioning component, through the cooperation of the mounting housing 201, clamping member 202, and torque component, forms a clamping mechanism to dock and clamp the waveguide flange. Its installation and disassembly are convenient; the operator only needs to hold the handle 210 to install or remove it. Compared to the traditional method of using tools and pins to dock the waveguide flange, this docking operation is much more convenient, thus greatly improving docking efficiency and practicality, facilitating widespread use. The structural design of the clamping force adjustment component allows for precise adjustment of the clamping force of the two clamping members 202 on the waveguide flange during use, thereby improving the applicability of this clamping fixture. The structural design of the clamping force reading component facilitates precise adjustment of the clamping force of the clamping members 202, accurately reading the pressure on the clamping members 202 before and after adjustment and during clamping, while also facilitating the reset of the initial reading to zero.

[0026] Please refer to Figure 6 and Figure 9-10The torque assembly includes torsion springs 206 sleeved on both ends of the connecting rod 203. Each torsion spring 206 includes a second connecting end 213 and a first connecting end 212. An adjusting block 207 is sleeved on the outer side of the first connecting end 212 and is fixedly connected to the corresponding connecting rod 203. A connecting block 208 is sleeved on the outer side of the second connecting end 213 and is fixedly connected to the corresponding clamping member 202. A first movable groove 211 adapted to the connecting block 208 is provided on the mounting housing 201. The connecting block 208 moves within the first movable groove 211, allowing it to slide within the first movable groove 211 during actual use to improve the stability of the clamping member 202's movement. In this embodiment, the connecting rod 203 and the mounting housing 201 adopt... In the fixed connection method, when the handle 210 is not subjected to external force, the torsion spring 206 is in its natural state, and the ends of the two clamping members 202 away from the handle 210 approach each other but do not abut. At this time, the torsion spring 206 is not under force and is in its natural state. When clamping is required, the operator pinches the handle 210 with his hand, so that the ends that were originally close to each other move away from each other, and then clamps it on the waveguide flange. During this process, the clamping member 202 rotates around the connecting rod 203, and the second connecting end 213 moves with the connecting block 208 and the clamping member 202, while the first connecting end 212 remains stationary. When the second connecting end 213 moves away from the first connecting end 212, a torque is generated, which causes the two clamping members 202 to be subjected to a force that brings them closer together, thereby clamping the waveguide flange.

[0027] Example 2 Please refer to Figure 4-12The connecting rod 203 is rotatably connected to the mounting housing 201. The clamping force adjustment assembly includes a ratchet 403 fixed to the outside of the connecting rod 203. An extension mounting box 409 is fixed on the mounting housing 201 and located on one side of the ratchet 403. A locking block 404 matching the ratchet 403 is rotatably connected to the inside of the extension mounting box 409. The locking block 404 has ratchet teeth that are adapted to the ratchet 403 on the side near the ratchet 403. An adjustment groove is opened on the side of the locking block 404 away from the ratchet 403. A positioning ball 407 abuts against the inside of the adjustment groove. A second spring 408 is connected to the side of the positioning ball 407 away from the locking block 404. The end of the second spring 408 away from the positioning ball 407 is connected to the inside of the extension mounting box 409. An adjusting rod 405 is fixed to one side of the locking block 404. One end of the adjusting rod 405 passes through the expansion mounting box 409 and is fixed with a release switch 406. The release switch 406 is slidably connected to the outside of the expansion mounting box 409. The expansion mounting box 409 has a second movable groove 410 adapted to the adjusting rod 405. One end of the connecting rod 203 passes through the second connecting ear 205 and is fixed with an adjusting knob 401. Specifically, a ratchet structure is formed between the locking block 404 and the ratchet 403. The adjusting groove includes a locking groove and a releasing groove. When the positioning ball 407 is located inside the locking groove, the locking block 404 is engaged with the ratchet 403. At this time, the connecting rod 203 can only rotate clockwise. Therefore, when the clamping member 202 moves around the connecting rod 203... When rotating counterclockwise, the connecting rod 203 will not rotate counterclockwise with it. When the positioning ball 407 is inside the release groove, the ratchet teeth of the locking block 404 separate from the ratchet 403. At this time, the connecting rod 203 can rotate freely. The release switch 406 and the adjusting rod 405 are used to drive the locking block 404 to rotate, so as to adjust the positioning ball 407 to be in the release groove or the locking groove. When it is necessary to adjust the clamping force, it is only necessary to adjust the position of the connecting end 212. When the connecting end 212 is far away from the connecting end 213, the clamping force increases. When the connecting end 212 is close to the connecting end 213, the clamping force decreases. The specific adjustment process is as follows: when it is necessary to increase the clamping force, the release switch 406 is turned. 06. Engage the locking block 404 with the ratchet 403, then rotate the adjusting knob 401 clockwise to make the connecting rod 203 rotate with the adjusting knob 401, which in turn drives the adjusting block 207 to rotate with the connecting rod 203, thereby moving the first connecting end 212 away from the second connecting end 213, thus increasing the clamping force. When it is necessary to decrease the clamping force, keep the clamping part 202 stationary, and move the release switch 406 to disengage the locking block 404 from the ratchet 403. Then rotate the adjusting knob 401 to move the first connecting end 212 closer to the second connecting end 213. When the appropriate clamping force is adjusted, move the release switch 406 to make the locking block 404 engage with the ratchet 403 again to position the connecting rod 203, thus decreasing the clamping force.

[0028] Please refer to Figure 11-12The clamping force reading assembly includes a reading disk 411 rotatably connected to the inside of the second connecting ear 205. A connecting rod 203 passes through the reading disk 411. A scale line group 412 is provided on the end face of the reading disk 411 near the adjusting knob 401, and an indicator arrow 402 is provided on the end face of the adjusting knob 401 away from the reading disk 411. Specifically, the clamping force is read by the indicator arrow 402 and the scale line group 412. It is necessary to first set the clamping force to the zero position. The setting method is that the clamping member 202 is in a non-working state. At this time, the torsion spring 206 is in a naturally unforced state. Then, manually turn the reading dial 411 so that its zero point coincides with the position indicated by the indicator arrow 402. At this time, the position of the zero point is the position where the clamping member 202 is not under force. Then, clamp the clamping member 202 onto the mating flange. During this process, the reading dial 411 rotates with the clamping member 202 at a certain angle. At this time, the position of the scale line on the scale line group 412 that is aligned with the indicator arrow 402 is the current pressure on the clamping member 202. When it is necessary to adjust the pressure, turn the adjustment knob 401 and the position of the scale line indicated by the indicator arrow 402 is the adjusted pressure.

[0029] Please refer to Figure 11 The outer side of the reading dial 411 is provided with several damping strips 413, and the inner side of the second connecting ear 205 is provided with several damping grooves 414 that are adapted to the damping strips 413. The second connecting ear 205 is connected to the reading dial 411 through the cooperation of the damping grooves 414 and the damping strips 413, thereby achieving a damping effect on the reading dial 411, preventing it from rotating freely and causing inaccurate clamping force readings, and facilitating the rotation adjustment of the reading dial 411. The cooperation of the damping grooves 414 and the damping strips 413 provides a positioning effect for the reading dial 411.

[0030] Please refer to Figure 11 The number of damping strips 413 is the same as the number of scale lines in the scale line group 412, and the number of damping grooves 414 is the same as the number of damping strips 413. At this time, whenever one of the damping strips 413 is moved to the inner side of the next adjacent damping groove 414, the distance that the scale line group 412 rotates with the reading dial 411 is one scale unit. This allows for more precise adjustment of the position of the reading dial 411 and the scale line group 412, thereby improving the accuracy of clamping force adjustment.

[0031] Please refer to Figure 5-7 Several anti-slip strips 209 are provided on the end faces of the two clamping parts 202 that are close to each other. The anti-slip strips 209 are made of soft rubber, which can increase the friction between the clamping parts 202 and the waveguide flange, prevent them from falling off to a certain extent, and protect the clamping parts 202 and the waveguide flange, thereby improving the service life of this clamping fixture.

[0032] Please refer to Figure 8-9The positioning assembly includes a first mounting hole 301 inside the clamping member 202. A mounting screw 302 is threaded into the first mounting hole 301. A positioning rod 303 is slidably connected to the mounting screw 302. A first spring 304 is provided between the positioning rod 303 and the mounting screw 302. The two ends of the first spring 304 are respectively connected to the mounting screw 302 and the positioning rod 303. The flanges of waveguide flange one 101 and waveguide flange two 102 are provided with mating holes 103 that match the positioning rod 303. With the positioning rod 303 in place, when the clamping fixture is clamped on the waveguide flange, the positioning rod 303 extends into the inner side of the mating hole 103 under the action of the first spring 304. The positioning rod 303 and the mating hole 103 further position the clamping fixture, which can effectively prevent it from falling off the waveguide flange without affecting its installation and disassembly. It has strong practicality. The initial position of the positioning rod 303 can be adjusted by the threaded connection between the mounting screw 302 and the clamping member 202 to adjust the positioning effect.

[0033] Please refer to Figure 5-12 The clamping member 202 has a second mounting hole 503 on its inner side, and a pressure sensor 501 is installed inside the second mounting hole 503. The end face of the clamping member 202 away from the mounting housing 201 has a second mounting hole 503 for displaying the pressure on the pressure sensor 501. Specifically, the end face of the pressure sensor 501 is flush with the end face of the clamping member 202. When the clamping member 202 is clamped on the waveguide flange, the pressure sensor 501 also acts on the waveguide flange. When the clamping member 202 is subjected to force, the pressure sensor 501 is also subjected to force. The force on the pressure sensor 501 is displayed on the display screen 502, which can intuitively display the clamping force at this time. This reading method further improves the accuracy. In actual use, the pressure sensor 501 can be threadedly connected to the clamping member 202 to facilitate the adjustment of the end face position of the pressure sensor 501.

[0034] The specific working principle of the waveguide flange mating clamping fixture provided by this invention is as follows: When using this clamping fixture, the clamping force must first be set to zero. The setting method is as follows: First, the clamping part 202 is in a non-working state. At this time, the torsion spring 206 is in a naturally unforced state. Then, manually turn the reading dial 411 so that its zero point position coincides with the position indicated by the indicator arrow 402. At this time, the position of the zero point is the position where the clamping part 202 is unforced. Then, clamp the clamping part 202 onto the mating flange. During this process, the reading dial 411 rotates with the clamping part 202 by a certain angle. At this time, the position of the scale line on the scale line group 412 that is aligned with the indicator arrow 402 is the current pressure on the clamping part 202. When it is necessary to adjust the pressure, turn the adjustment knob 401 and the position of the scale line indicated by the indicator arrow 402 is the adjusted pressure. When the clamping force needs to be increased, the release switch 406 is activated to engage the locking block 404 with the ratchet 403. Then, the adjustment knob 401 is turned clockwise, causing the connecting rod 203 to rotate with the adjustment knob 401. This, in turn, causes the adjustment block 207 to rotate with the connecting rod 203, thereby moving the first connecting end 212 away from the second connecting end 213, thus increasing the clamping force. When the clamping force needs to be decreased, the clamping member 202 is kept stationary, and the release switch 406 is activated to disengage the locking block 404 from the ratchet 403. Then, the adjustment knob 401 is rotated to bring the first connecting end 212 closer to the second connecting end 213. When the appropriate clamping force is reached, the release switch 406 is activated again to engage the locking block 404 with the ratchet 403 to position the connecting rod 203, thus decreasing the clamping force.
