Description

Technical Field

[0002] Metal cavity filters, hereinafter referred to as "filters", are widely used in base station communication systems. In the filter manufacturing process, debugging is a key process that directly affects the performance and production cost of the filter. The debugging method of the new filter in the prior art is that a network analyzer is connected to the filter through a cable to monitor the filter performance, and a number of split pins are tightened in the straight-through holes of the filter cover. The split pins are manually pressed down or pushed up multiple times to adjust the depth of the split pins until the monitoring result of the network analyzer meets the standard.

[0003] In the prior art, when debugging the depth, needle-nosed pliers are usually used to clamp the cotter pin so that the cotter pin loses the tension force and the depth can be adjusted up and down. However, when manually using needle-nosed pliers to clamp the cotter pin, the clamping force cannot be accurately controlled. If the clamping force is too small, the cotter pin cannot be pulled. If the clamping force is too large, the cotter pin may be easily flattened and damaged. In addition, the depth cannot be accurately controlled during the process of pulling the cotter pin. The debugging operation is inconvenient and inefficient, and cannot meet the use requirements. Based on the above situation, we propose a device for debugging a new filter. Utility Model Content

[0026] Working principle: When in use, the peripheral conveyor 5 and the pressing module 6 are separated from the product carrier board 4. The filter to be debugged is placed on the peripheral conveyor 5, and then the filter is fixed with external screws to ensure that the conductive rubber ring on the peripheral conveyor 5 is in contact with the filter. Then the peripheral conveyor 5 is placed in the movable groove provided on the product carrier board 4, and it is confirmed that the product carrier board 4 and the peripheral conveyor 5 are correctly matched. The peripheral conveyor 5 is locked to the product carrier board 4 with T-shaped pressing bolts, and then the pressing module 6 is fixed to the top of the product carrier board 4 with two T-shaped fixing bolts, and each adjusting screw 601 and the anti-locking nut 602 corresponds to a debugging position of the filter cotter pin. Then the filter channel is selected, and the cable connector of the external network analyzer is connected to the filter. The filter performance is monitored in real time through the network analyzer;

[0027] Then, use an external tool to positively adjust the adjusting screw 601, and the adjusting screw 601 rotates and moves downward in the corresponding anti-locking nut 602. While the adjusting screw 601 moves downward, the cotter pin on the filter is pressed down to increase the depth of the cotter pin. After adjustment, the thread locking force between the anti-locking nut and the adjusting screw 601 can be used to fix it. If the depth of the cotter pin is too large, select a number of cotter pins whose depth is to be reduced in the filter, and reversely adjust the adjusting screw 601 at the corresponding position on the pressing module 6. While the adjusting screw 601 rotates and moves upward, a portion of the filter is withdrawn. The space where the adjusting screw 601 contacts the cotter pin is adjusted, and then according to the selected filter channel, the air path switching valve 7 is manually dialed to select the corresponding push cylinder 2, and the foot valve 8 is manually stepped on. The air path of the compressed air is switched from the original outlet 1 of the foot valve 8 to the channel where the push cylinder 2 returns to the air inlet, and is switched to the channel where the outlet 2 of the foot valve 8 is connected to the air path switching valve 7 to the air inlet where the push cylinder 2 extends. At this time, the selected push cylinder 2 performs the extension action, and the other push cylinder 2 maintains the retracted state. When one push cylinder 2 performs the extension action, it drives the jacking module 3 to move upward , the lifting module 3 drives the plunger 304 on it to move upward, and the hole of the filter cavity supports the cotter pin. When the plunger 304 contacts the cotter pin, the lifting module 3 continues to move upward and compresses the spring 303. At this time, the spring 303 receives the force transmitted by the plunger 304 and generates a rebound force sufficient to push the cotter pin, so that the selected cotter pin moves upward and reduces the depth. The unselected cotter pin will not move upward due to the restriction of the adjusting screw 601 on the pressing module 6, and the depth will not change. Repeat the above debugging until the filter performance displayed by the network analyzer is qualified. After the inspection is completed, switch Go to the next channel of the filter and repeat the above debugging actions to continue debugging. After completing the debugging of this filter, the pressing module 6 can be removed from the product carrier plate 4 to remove the cover on the top of the filter. The filter can be removed from the peripheral transport device 5. By using compressed gas as the power source to drive the extrusion debugging and coordinating the extrusion adjustment of the adjusting screw 601, the depth of the selected cotter pin can be effectively and accurately debugged, thereby improving the debugging efficiency and facilitating personnel operation. There is no need for personnel to directly clamp the cotter pin for debugging, which can effectively reduce the risk of damage to the cotter pin during the debugging process.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
