Description

Technical Field

[0001] This invention relates to the technical field of tooling, and more specifically to a microwave component testing tooling. Background Technology

[0002] Microwave components are one of the key components in active phased array radar. They are used to amplify radar microwave signals, reduce noise, and perform frequency conversion through microwave devices housed in a box. When testing microwave components, they need to be clamped and fixed using a man-made fixture. However, the existing microwave component testing fixtures are cumbersome and inefficient in clamping and releasing the microwave components. In addition, the microwave components are difficult to dissipate heat during testing, resulting in poor heat dissipation and poor testing results. Summary of the Invention

[0003] The purpose of this invention is to provide a microwave component testing fixture to overcome the above-mentioned defects in the prior art.

[0004] A microwave component testing fixture includes a worktable, a limiting mechanism, and a heat dissipation mechanism. The worktable is provided with a limiting base, and the limiting base is provided with a limiting groove for placing the microwave component to be tested.

[0005] The limiting mechanism is located on the limiting base and is used to clamp and fix the microwave component.

[0006] The heat dissipation mechanism is located on the clamp of the limiting mechanism and is used to dissipate heat from the microwave components under test.

[0007] Preferably, the limiting mechanism further includes a guide rod, a spring, and a plug-in assembly. The clamping plate is U-shaped with its opening facing downwards. One side of the clamping plate is slidably connected to the guide rod on the worktable. A baffle is fixed to the top of the guide rod. The spring is fitted onto the guide rod and located between the clamping plate and the worktable. The plug-in assembly is located on the other side of the clamping plate and is used to limit the clamping plate.

[0008] Preferably, the plug-in assembly includes a second guide rod, a second spring, a plug block, and a limiting plate. The limiting plate is fixed to the clamp and has a first inclined surface at its bottom. The limiting base has a positioning groove that mates with the limiting plate. The second guide rod is slidably connected to the limiting base and a bracket on the limiting base. The plug block is fixed to the inner end of the second guide rod and is located in the mounting groove of the limiting base. The plug block has a second inclined surface that mates with the first inclined surface. The limiting plate has a slot that mates with the plug block. The second guide rod has a push plate. The second spring is sleeved on the second guide rod and is located between the push plate and the bracket.

[0009] Preferably, the heat dissipation mechanism includes an air intake box, an air intake plate, blades, and a motor. The air intake plate is "U"-shaped and its opening faces the clamping plate. The air intake plate is fixed to one side of the clamping plate, the air intake box is fixed to one side of the air intake plate, the motor is fixed to the outside of the air intake box, and the blades are located in the air intake box and mounted on the output shaft of the motor.

[0010] Preferably, the second guide rod has an L-shaped structure.

[0011] The present invention has the following advantages:

[0012] When using this invention, simply press down on the clamping plate to clamp and fix the microwave component through the plug-in assembly. To release the microwave component, simply pull outward on the guide rod two. The plug on the guide rod two will disengage from the limiting plate, and the microwave component will be released under the elastic force of the spring two. The clamping and releasing of the microwave component is very convenient. During testing, the heat generated by the microwave component can be discharged through the air duct and air box via the motor and blades of the heat dissipation mechanism.

[0021] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of the present invention, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the concept and technical solutions of the present invention.

[0022] like Figure 1-9 As shown, the present invention provides a microwave component testing fixture, including a workbench 1, a limiting mechanism 3, and a heat dissipation mechanism 4. The workbench 1 is provided with a limiting base 2, and the limiting base 2 is provided with a limiting groove for placing the microwave component 5 to be tested. The limiting mechanism 3 is provided on the limiting base 2 and is used to clamp and fix the microwave component 5. The heat dissipation mechanism 4 is provided on the clamping plate 31 of the limiting mechanism 3 and is used to dissipate heat from the microwave component 5 under test.

[0023] It should be noted that the limiting mechanism 3 also includes a guide rod 32, a spring 34 and a plug-in assembly 35. The clamping plate 31 is "U" shaped and the opening faces downward. One side of the clamping plate 31 is slidably connected to the guide rod 32 on the worktable 1. A baffle 33 is fixed to the top of the guide rod 32. The spring 34 is sleeved on the guide rod 32 and located between the clamping plate 31 and the worktable 1. The plug-in assembly 35 is located on the other side of the clamping plate 31 and is used to limit the clamping plate 31.

[0024] Furthermore, the plug-in assembly 35 includes a second guide rod 354, a second spring 359, a plug block 357, and a limiting plate 351. The limiting plate 351 is fixed on the clamping plate 31 and has a first inclined surface 352 at its bottom. The limiting base 2 has a positioning groove that cooperates with the limiting plate 351. The second guide rod 354 is slidably connected to the limiting base 2 and the bracket 356 on the limiting base 2. The plug block 357 is fixed to the inner end of the second guide rod 354 and is located in the mounting groove of the limiting base 2. The plug block 357 has a second inclined surface 358 that cooperates with the first inclined surface 352. The limiting plate 351 has a slot 353 that cooperates with the plug block 357. The second guide rod 354 has a push plate 355. The second spring 359 is sleeved on the second guide rod 354 and is located between the push plate 355 and the bracket 356. The second guide rod 354 has an L-shaped structure.

[0025] In addition, the heat dissipation mechanism 4 includes an air intake box 42, an air intake plate 41, blades 44 and a motor 43. The air intake plate 41 is "U" shaped and its opening faces the clamping plate 31. The air intake plate 41 is fixed to one side of the clamping plate 31. The air intake box 42 is fixed to one side of the air intake plate 41. The motor 43 is fixed to the outside of the air intake box 42. The blades 44 are located in the air intake box 42 and are disposed on the output shaft of the motor 43.

[0026] Detailed implementation methods and principles:

[0027] In practical application, the microwave component 5 to be tested is placed into the limiting groove of the limiting base 2. Then, the clamping plate 31 is pressed down, and the clamping plate 31 presses the microwave component 5. The spring 34 on the guide rod 32 is compressed, and the limiting plate 351 on the clamping plate 31 is inserted into the positioning groove on the limiting base 2. The inclined surface 352 at the bottom of the limiting plate 351, through the inclined surface 358 on the insert 357, pushes the insert 357 into the mounting groove of the limiting base 2. The spring 359 on the guide rod 354 is compressed, and the limiting plate 351 continues to move downward. When the insert 357 is aligned with the slot 353 on the limiting plate 351, under the elastic force of the spring 359, the insert 357 is inserted into the slot 353, pressing against the clamping plate. 31. The microwave component 5 is clamped and fixed. At this time, the air duct 41 is directly facing the heat dissipation port of the microwave component 5. Then, the microwave component 5 is tested by the testing device. During the test, the motor 43 is turned on. The output shaft of the motor 43 drives the blades 44 to rotate. The blades 44 introduce outside air into the air duct box 42 and the air duct 41 to dissipate the heat generated by the microwave component 5 and cool it down. After the microwave component 5 is tested, the guide rod 354 is pulled outward. Under the action of the spring 34 on the guide rod 32, the clamp 31 moves upward to release the microwave component 5. Then, the worker removes the tested microwave component 5 from the limiting groove of the limiting base 2 and puts in the microwave component 5 to be tested.

[0028] In summary, this invention only requires pressing down the clamping plate 31 to clamp and fix the microwave component 5 through the plug-in assembly 35. When releasing the microwave component 5, simply pull the guide rod 354 outward, and the plug 357 on the guide rod 354 will disengage from the limiting plate 351. Under the elastic force of the spring 359, the microwave component 5 can be released. The clamping and releasing of the microwave component 5 is very convenient. During testing, the heat generated by the microwave component 5 can be discharged through the air duct 41 and the air box 42 by the motor 43 and blades 44 of the heat dissipation mechanism 4.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the present invention and technical solution to other situations without modification, are all within the protection scope of the present invention.
