The upper portion of the resonant rod 130 is fixed to the cover plate 110, and the lower portion is suspended in the resonant cavity 140. The cover plate 110 is provided with a ring-groove-shaped deformation region 111 around the upper portion of each resonance bar 130.

The debugging device 300 comprises a clamping part 310 and a sliding sleeve 320 sleeved outside the clamping part 310, wherein the sliding sleeve 320 can slide up and down relative to the clamping part 310. The head of the resonant rod 130 extends out of the cover plate 110, and is matched and connected with the clamping part 310 of the debugging device 300 during debugging. When the sliding sleeve 320 slides downward, the clamping portion 310 is pressed to close and clamp the head of the resonant rod 130, and when the sliding sleeve 320 slides upward, the clamping portion 310 is opened and separated from the head of the resonant rod 130. The head of each resonant rod 130 is the debug point 131.
As shown in fig. 1, 3 to 6, a debugging fixture 200 for assisting automatic debugging and achieving accurate and fast debugging of the frequency parameters of the filter includes a fixture box 210, a fixture cover 220 and a bottom plate 240, wherein the fixture box 210 is disposed on the bottom plate 240. The jig box 210 and the jig cover 220 cover a space for accommodating a filter to be tuned. The fixture cover 220 has a plurality of through holes 221 corresponding to the debugging sites 131 of the filter 100 to be debugged for the clamping portion 310 of the debugging apparatus 300 to pass through, and a groove 223 is formed on the lower surface of the fixture cover 220 around each through hole 221. A protrusion 222 surrounding each through hole 221 is formed between each through hole 221 of the lower surface of the jig cover 220 and its adjacent groove 223. In this embodiment, the lower surface of the protrusion 222 is flush with the lower surface of the clamp cover 220, the area of the upper surface of the clamp cover 220 opposite to the protrusion 222 is a debugging area 224, and the area of the upper surface of the clamp cover opposite to the groove 223 is a deformation area 225.
As shown in fig. 2, the surface of the cover plate 110 of the cavity filter 100 to be debugged includes a screw boss 112 in addition to a plurality of debugging points 131. As shown in fig. 4, the jig cover 220 is provided with a clearance 226 for clearance of the screw boss 112. In some embodiments, the protrusion 222 and the groove 223 of the clamp cover 220 may be circular rings. In other embodiments, in the case that the surface of the cover plate 110 of the cavity filter 100 to be debugged has the screw boss 112, the protrusion 222 and the groove 223 may also be arc-shaped larger than a semicircle, and the arc-shaped portion corresponding to the same circle as the protrusion and the groove and smaller than the semicircle is used for setting the clearance 226, so that the debugging point and the screw boss can be arranged compactly.
As shown in fig. 3, the clamping box 210 includes a peripheral positioning wall 211, a corner of the peripheral positioning wall is an arc angle, and a guide slope 212 is disposed above the arc angle. The bottom plate 240 is provided with positioning mechanisms 230 at two sides of the clamp box 210 for pressing the clamp cover plate 220, and in this embodiment, the positioning mechanisms 230 are air cylinder pressing mechanisms. A notch 213 is formed above the vertical wall of the clamp box 210, and an air cylinder of the air cylinder pressing mechanism penetrates through the notch 213 to press the clamp cover plate 220. When the filter to be debugged is clamped, the filter to be debugged slides into the clamp box 210 along the guide inclined plane 212, the clamp cover plate 220 is covered, and then the clamp cover plate is pressed by the air cylinder pressing mechanism, so that clamping can be realized, and the clamping efficiency can be improved by the mode.
The debugging method based on the debugging clamp comprises the following steps:
➀ placing the filter to be debugged into the clamp box of the debugging clamp, covering the clamp cover plate of the debugging clamp, aligning the debugging points of the filter to be debugged with the through holes on the clamp cover plate one by one, and tightly pressing the clamp cover plate by the positioning mechanisms arranged around the clamp box;
➁ the clamping part of the debugging device passes through a through hole on the clamp cover plate, the sliding sleeve of the debugging device sleeved outside the clamping part slides downwards to prop against the debugging area of the upper surface of the clamp cover plate, the deformation area of the clamp cover plate deforms under stress, and the bulge of the lower surface of the clamp cover plate completely clings to the upper surface of the filter to be debugged;
➂ when the sliding sleeve is pressed against the debugging region of the upper surface of the clamp cover plate, the sliding sleeve compresses the clamping part to connect the clamping part with the debugging point position in the through hole, and the clamping part stretches or presses down the debugging point position to debug the debugging point position frequency parameter;
➃ debugging a debugging position, the sliding sleeve moves upwards to leave the upper surface of the clamp cover plate, the clamping part is separated from the debugging position, and the debugging device moves to the position above the other debugging position;
➄ the debugging device repeats steps ➁ - ➃ until all debugging points of the filter to be debugged are debugged.
As shown in fig. 5 and 6, when the filter cover 110 is adjusted, the fixture cover 20 is attached to the upper surface of the filter cover 110, the sliding sleeve 320 outside the clamping portion 310 slides downward against the adjustment region 224 of the fixture cover 220, the elastic deformation region 225 of the fixture cover 220 deforms under a force, and the adjustment region 224 of the fixture cover 220 can completely attach to the upper surface of the filter cover 110. When the clamping portion 310 stretches the point 131 to be debugged, the deformation zone 111 of the filter is limited to be only the area within the debugging area 224 of the cover plate of the clamp, and the other places are not influenced by tension. Because the downward jacking force of the sliding sleeve 320 and the upward pulling force of the clamping part are mutually offset, the rigidity of the whole clamp does not need to be too strong, and the pressing force of an air cylinder on the debugging clamp does not need to be too large. Therefore, the debugging method can improve the debugging yield and the stress condition of the equipment.
