Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, and in particular to a clamping tooling for inspection fixtures. Background Technology

[0002] A clamping fixture is a clamp or device used to fix and clamp products. It is often used for positioning and clamping when testing the dimensional accuracy, shape, or electromagnetic performance of radomes. Its core function is to ensure that the radome remains stable and free from deformation during the testing process, while meeting the operational requirements of the testing equipment.

[0003] The existing clamping mechanism is cumbersome to operate and inefficient. It is prone to damage during repeated use, which affects the detection accuracy. In addition, due to the lack of a precise positioning structure, the radome is prone to displacement during placement, especially when subjected to external force disturbance during the detection process. Its instability is insufficient and it is easy to cause data errors. Utility Model Content

[0004] The purpose of this invention is to provide a clamping fixture that can quickly position and stably clamp the radome, avoiding detection errors caused by displacement or loosening of the radome during the detection process, and significantly improving the accuracy of the detection.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a clamping fixture, comprising a fixture plate and a clamping structure disposed on the fixture plate; the fixture plate forms a detection groove for placing an radome, the clamping structure comprising a clamping block for clamping the radome and an elbow clamping mechanism for driving the clamping block to move; the clamping block has a plurality of spaced positioning teeth, the radome is provided with a positioning ring groove, the positioning teeth are inserted into the positioning ring groove and abut against the fixture plate to restrict the radome from detaching from the detection groove. By adopting the above technical solution, the clamping block is clamped on the radome, and the positioning teeth on the clamping block cooperate with the positioning ring groove to achieve rapid positioning and stable clamping of the radome, avoiding detection errors caused by displacement or loosening of the radome during the detection process, and significantly improving the accuracy of the detection.

[0006] A further feature of this invention is that the inner wall of the detection groove is provided with a plurality of spaced abutting teeth, which abut against the outer periphery of the radome. By adopting the above technical solution, the radome can be pre-positioned during placement, effectively reducing the initial placement deviation and further improving the accuracy of detection.

[0007] A further feature of this invention is that the positioning teeth include cooperating teeth and clamping teeth disposed between the cooperating positioning teeth. The cooperating teeth and the abutting teeth are disposed opposite to each other. By adopting the above technical solution, the clamping teeth and the cooperating teeth form multi-point limiting, and the abutting teeth provide support for the clamping teeth and the cooperating teeth, preventing the pressure block from breaking due to excessive clamping force, thus making the structure more reliable.

[0008] A further feature of this invention is that the width of the clamping tooth is greater than that of the cooperating tooth. By adopting the above technical solution, the structural strength of the clamping tooth is higher, while the cooperating tooth provides auxiliary limiting, thus balancing clamping strength and stability.

[0009] A further feature of this invention is that the tooling plate is provided with a positioning slot, and the bottom of the pressure block is provided with a mounting protrusion. The mounting protrusion is inserted into the positioning slot. By adopting the above technical solution and setting the insertion and engagement structure between the positioning slot and the mounting protrusion, the pressure block can be quickly disassembled and replaced, which facilitates the testing of radomes of different models or specifications and enhances the adaptability of the tooling.

[0010] A further feature of this invention is that a disassembly groove is formed between the abutting teeth. By adopting the above technical solution, without affecting the clamping and positioning accuracy, it is convenient to insert tools or fingers to remove or replace the antenna cover, thereby improving the ease of operation.

[0011] A further feature of this invention is that the elbow clamp mechanism includes a base, a pressure rod, a first movable rod, a second movable rod, and a handle. The pressure rod passes through one end of the first movable rod, and one end of the handle is hinged to the end of the first movable rod away from the pressure rod. The end of the first movable rod away from the pressure rod is hinged to the base, and one end of the second movable rod is hinged to the middle of the handle. The end of the second movable rod away from the handle is hinged to the base. By adopting the above technical solution, the elbow clamp mechanism has a reasonable structure. The operating handle drives the first and second movable rods to achieve the clamping and releasing functions in conjunction. It has the advantages of easy operation and stable clamping force. At the same time, it has a compact structure and is easy to integrate into tooling.

[0012] A further feature of this invention is that the pressure rod has a movable groove inside, the movable groove has a pressing block that can move up and down, and a pressing spring is provided between the pressing block and the pressure rod. By adopting the above technical solution, a movable groove is provided inside the pressure rod and a pressing spring is configured, so that the pressing block has a certain elastic buffer space, thereby enhancing the pressing and fitting effect, and avoiding damage to the test piece due to overpressure.

[0013] A further feature of this invention is that the clamping block is provided with a groove, and a slider is slidably disposed in the groove. The slider is provided with a support foot. By adopting the above technical solution, the slider slides in the groove so that the support foot can open. The support foot is always in close contact with the surface of the radome, forming multi-point contact with the radome, providing a more uniform clamping force and making the clamping more stable.

[0014] A further feature of this invention is that a third movable rod is hinged to the slider, and the end of the third movable rod away from the slider is hinged to the pressure rod. By adopting the above technical solution, the third movable rod is set as a connecting medium between the slider and the pressure rod. When the pressing block contacts the antenna cover, the pressure rod continues to move downward, causing the third movable rod to open to both sides, driving the slider to slide to both sides, so that the support legs can open to both sides smoothly, thereby improving the pressing effect.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. The positioning teeth on the pressure block of this utility model engage with the positioning ring groove on the radome, ensuring that the radome is in a stable and reliable position during the testing process and effectively avoiding displacement.

[0017] 2. This utility model uses an elbow clamping mechanism to achieve clamping, which is simple in structure and easy to operate. The clamping and releasing of the pressure block can be completed by the handle, which improves clamping efficiency and is suitable for batch operation.

[0018] 3. The height of the pressure rod of this utility model can be freely adjusted up and down within the first movable rod to adapt to antenna covers or pressure plates of different thicknesses, thereby improving the flexibility of the tooling. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] Example 1:

[0029] like Figures 1 to 5 As shown, this embodiment provides a clamping fixture, including a fixture plate 1 and a clamping structure disposed on the fixture plate 1. The fixture plate 1 has a detection groove 11 for placing an radome. The detection groove 11 is used to initially limit the radome. The clamping structure includes a pressing block 2 for clamping the radome and an elbow clamping mechanism 4 for driving the pressing block 2 to move. The pressing block 2 has a plurality of spaced positioning teeth 21. The positioning teeth 21 correspond to the positioning ring grooves 3 disposed on the radome. By inserting the positioning teeth 21 into the positioning ring grooves 3, the radome is effectively prevented from dislodging from the detection groove 11, and its accurate positioning is achieved.

[0030] The inner wall of the detection groove 11 is provided with several spaced abutment teeth 111, which are used to abut against the outer periphery of the radome, so that the radome can be pre-positioned during placement, effectively reducing the initial placement deviation and improving the accuracy of detection.

[0031] The positioning tooth 21 includes a cooperating tooth 212 and a clamping tooth 211 disposed between adjacent cooperating teeth 212. The cooperating tooth 212 is disposed opposite to the abutting tooth 111 on the inner wall of the detection groove 11. The clamping tooth 211 and the cooperating tooth 212 form a multi-point limit and provide support during the clamping process, thereby enhancing the stability of the structure. The width of the clamping tooth 211 is greater than that of the cooperating tooth 212, and it plays the main clamping role during the clamping process. At the same time, the cooperating tooth 212 plays an auxiliary limiting role, ensuring that the clamping force is reasonably distributed, improving the structural strength of the pressure block 2, and avoiding the risk of the pressure block 2 breaking.

[0032] The bottom of the pressure block 2 is provided with a mounting protrusion 22, which is inserted into the positioning slot 12 on the tooling plate 1 to realize the quick positioning and disassembly of the pressure block 2. This facilitates the replacement of pressure blocks 2 of different specifications and models to adapt to different types of radomes, thereby enhancing the versatility and flexibility of the tooling.

[0033] A disassembly groove 112 is also formed between the abutment teeth 111, which facilitates the subsequent insertion of tools or fingers to disassemble or replace the antenna cover, thus improving the ease of operation.

[0034] The tooling plate 1 is equipped with an elbow clamping mechanism 4, which includes a base 41, a pressure rod 42, a first movable rod 43, a second movable rod 44, and a handle 45. The pressure rod 42 is vertically inserted through one end of the first movable rod 43. One end of the handle 45 is hinged to the end of the first movable rod 43 away from the pressure rod 42, and this end is also hinged to the base 41. One end of the second movable rod 44 is hinged to the middle of the handle 45, and the other end is hinged to the base 41. The above structure forms a typical elbow clamping structure. When the operator pushes the handle 45 down, the relative movement between the first movable rod 43 and the second movable rod 44 drives the pressure rod 42 to move down, thereby clamping the pressure block 2. When the handle 45 is operated in the opposite direction, the clamping force can be released. The operation is simple and efficient, and the clamping force is stable.

[0035] The pressure rod 42 is provided with an upper locking nut 46 and a lower locking nut 47 that are threaded together. An upper fixing plate 48 is provided between the upper locking nut 46 and the first movable rod 43, and a lower fixing plate 49 is provided between the lower locking nut 47 and the first movable rod 43. The upper fixing plate 48 is provided with a downwardly bent upper limit protrusion 481, and the lower fixing plate 49 is provided with an upwardly bent lower limit protrusion 491. Together, they form a limiting groove. The first movable rod 43 passes through the limiting groove, which effectively limits its range of motion and ensures that the components of the elbow clamp mechanism 4 cooperate stably during repeated operation.

[0036] The basic working principle of this embodiment is as follows: First, the operator manually places the radome to be tested into the testing groove 11 on the tooling plate 1. The outer peripheral edge of the radome contacts the abutment teeth 111 on the testing groove 11 to ensure that it is centered. Next, a pressure block 2 matching the model of the radome is selected, and the mounting protrusion 22 at the bottom of the pressure block 2 is inserted into the corresponding positioning slot 12 on the tooling plate 1 to complete the installation of the pressure block 2. At this time, the cooperating teeth 212 and the clamping teeth 211 on the pressure block 2 engage with the positioning ring groove 3 of the radome to form a multi-point engagement. The operator first presses down on the handle 45 of the elbow clamp mechanism 4 to achieve precise positioning of the radome. Then, the operator presses down on the handle 45 of the elbow clamp mechanism 4. The handle 45 drives the first movable rod 43 and the second movable rod 44 to move the pressure rod 42 downward, thereby pressing the pressure block 2 as a whole, so that the radome is stably held in the detection groove 11. After the pressing is completed, the entire fixture is in the detection ready state and can enter the subsequent detection or testing process. If the radome needs to be replaced, simply lift the handle 45 to release the elbow clamp mechanism 4, remove the pressure block 2 and replace it with a matching new pressure block 2, and repeat the above operation.

[0037] Example 2:

[0038] Based on the clamping fixture described in Example 1, this example further optimizes the clamping structure to give it better buffering performance and self-adaptive ability, avoiding workpiece damage caused by uneven clamping force or mismatched clamping surface shape.

[0039] like Figures 6 to 7 As shown, a movable groove 421 extending vertically is provided inside the pressure rod 42. The bottom opening of the movable groove 421 faces the antenna cover direction. A pressing block 422 that can move up and down is provided inside the movable groove 421. The shape of the pressing block 422 matches the inner cavity of the movable groove 421. A pressing spring 423 is provided between the pressing block 422 and the pressure rod 42. One end of the pressing spring 423 abuts against the pressure rod 42, and the other end abuts against the pressing block 422. By setting the spring structure, a buffer can be provided when the pressing force is applied, reducing the damage to the pressing block 2 and improving the service life of the tooling.

[0040] The clamping block 422 has a horizontally arranged groove 4221 inside. Two sliders 424 are slidably arranged in the groove 4221. The sliders 424 can move left and right in the groove 4221. The bottom of the sliders 424 is provided with a support foot 4241 for contacting the surface of the radome and applying a clamping force. A third movable rod 425 is hinged to the slider 424. The other end of the third movable rod 425 is hinged to the pressure rod 42. When the clamping block 422 moves downward and contacts the surface of the radome, the third movable rod 425 will drive the slider 424 to move in the groove 4221 under the action of the clamping force, so that the support foot 4241 opens and fits more fully with the radome, making the clamping process more stable and reliable.

[0041] The basic working principle of this embodiment is as follows: The operator places the radome in the detection slot 11, uses the protrusions around the detection slot 11 to achieve initial positioning, and inserts the pressure block 2 into the tooling plate 1. Then, the operator presses down the operating handle 45, which drives the first movable rod 43 and the second movable rod 44 to move the pressure rod 42 downward. The compression spring 423 is compressed, and the pressure block 422 gradually presses the upper surface of the radome through the slider 424 and the support foot 4241 to achieve multi-point contact. While achieving stable pressing, it reduces the risk of damage.

[0042] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
