Description
Technical Field
[0001] This utility model belongs to the technical field of insulation testing equipment, and specifically relates to a ceramic tube insulation testing device. Background Technology
[0002] In the ignition system of aerospace engines, ceramic tubes made of ceramic materials are often used as insulating parts for ignition devices, ignition cables, and ignition nozzle connections. In order to ensure the insulation performance of ceramic tubes, insulation tests need to be performed on them after production.
[0003] Currently, Chinese utility model patent CN216595213U discloses a ceramic tube insulation testing device, including a base. At both ends of the top of the base are mounting brackets. A first insulating bushing and a second insulating bushing are coaxially mounted on the top of the mounting brackets at both ends. A first clamping device is axially movable on the first insulating bushing, and a second clamping device is axially movable on the second insulating bushing corresponding to the first clamping device. An elastic pre-tightening device is provided between the clamping end of the second clamping device and the second insulating bushing. This utility model has the function of efficiently and conveniently clamping ceramic tubes.
[0004] In summary, although this insulation testing device can achieve the purpose of rapid clamping, it still has certain problems in use. For example, the support structure and clamping structure of the insulation testing device are fixed, and after use, the support structure and clamping structure cannot be stored in the base at the bottom. The overall space occupied is large, and storage is extremely inconvenient. At the same time, the two clamps of the insulation testing device are of fixed size and can only be used to clamp ceramic tubes within the diameter of the clamps. When the inner diameter of the ceramic tube is larger than the clamp, it is impossible to clamp and fix the ceramic tube, resulting in poor applicability. Utility Model Content
[0005] The purpose of this utility model is to provide a ceramic tube insulation testing device, which has the advantages of being easy to fold and store and having strong applicability.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a ceramic tube insulation testing device, including a storage base, a support base symmetrically hinged inside the storage base, a storage groove opened on the opposite side of the two support bases, a connecting block arranged inside the storage groove, a sleeve hinged to the top of the connecting block, a connecting base arranged inside the sleeve, an installation block hinged to one end of the connecting base, a chuck fixedly connected to the side of the installation block away from the connecting base, a limit groove opened on the opposite side of the two chucks, the number of the limit grooves being four, an adjusting screw rotatably connected inside the limit groove, a fixing block threadedly connected to the surface of the adjusting screw, an extension block fixedly connected to the fixing block, and a connecting groove opened inside the chuck.
[0007] The above technical solution is as follows: This utility model uses a hinge between the storage base and the support base. The support base can be flipped and stored inside the storage base, and the sleeve can be stored inside the support base through the action of the connecting block. Then, the chuck can be flipped to the top of the connecting base through the hinge between the mounting block and the connecting base. This allows the entire device to be folded when not in use, reducing the space occupied and facilitating storage and transportation. By rotating the adjusting screws, under the action of the bevel gear, the four adjusting screws rotate simultaneously. This causes the extension block to be driven out of the limiting groove under the action of the fixing block, extending the diameter of the chuck. This makes it suitable for clamping and fixing more large-sized ceramic tubes, improving its applicability.
[0008] The present invention is further configured such that the surface of the connecting block is symmetrically fitted with sliders, and the inside of the storage groove is provided with a sliding groove that is slidably connected to the sliders.
[0009] The above technical solution involves sliding and limiting the connecting block.
[0010] The present invention is further configured such that a limit bolt is threadedly connected to the side of the connecting block away from the storage groove, and the limit bolt is used in conjunction with the inner wall of the storage groove.
[0011] The above technical solution is adopted to limit the position of the connecting block inside the storage slot.
[0012] The present invention is further configured such that both ends of the storage base are threadedly connected to locking bolts, one end of which penetrates into the interior of the storage base and is threadedly connected to the support base.
[0013] The above technical solution involves limiting the position of the erected support base.
[0014] The present invention is further configured such that a guide block is provided on the surface of the connecting seat, and a guide groove is provided inside the sleeve to slide and connect with the guide block.
[0015] The above technical solution is adopted to limit the sliding of the connecting seat inside the sleeve.
[0016] The present invention is further configured such that a support spring is engaged between the connecting seat and the sleeve.
[0017] The above technical solution provides reverse support elasticity to the connecting seat.
[0018] The present invention is further configured such that one end of each of the four adjusting screws passes through the interior of the connecting groove and is fixedly sleeved with a bevel gear that meshes with each other.
[0019] The above technical solution allows for the simultaneous rotation of other adjusting screws when one adjusting screw is turned.
[0020] The present invention is further configured such that sliding blocks are symmetrically mounted on the surface of the extension block, and a sliding groove is provided inside the limiting groove to slide and connect with the sliding blocks.
[0021] The above technical solution involves sliding and limiting the movement of the extension block.
[0022] In summary, this utility model has the following beneficial effects:
[0023] 1. This utility model uses a hinge between the storage base and the support base. The support base can be flipped and stored inside the storage base. The sleeve can be stored inside the support base through the action of the connecting block. The chuck can be flipped to the top of the connecting base through the hinge between the mounting block and the connecting base. This allows the entire device to be folded when not in use, reducing the space occupied and making it convenient for storage and transportation.
[0024] 2. This utility model, by rotating the adjusting screw, causes four adjusting screws to rotate simultaneously under the action of the bevel gear. This, in turn, causes the extension block to disengage from the limiting groove under the action of the fixing block, thereby extending the diameter of the chuck and making it suitable for clamping and fixing more large-sized ceramic tubes, thus improving its applicability.

A connecting block 4 is disposed inside the housing groove 3, and sliders 14 are symmetrically mounted on the surface of the connecting block 4. A sliding groove 15 is provided inside the housing groove 3 to slide and limit the movement of the connecting block 4. A limit bolt 16 is threadedly connected to the side of the connecting block 4 away from the housing groove 3. The limit bolt 16 cooperates with the inner wall of the housing groove 3. The limit bolt 16 ensures the connecting block 4 is positioned within the housing groove. The internal position is limited. The top of the connecting block 4 is hinged to the sleeve 5. The sleeve 5 is provided with the connecting seat 6. The surface of the connecting seat 6 is provided with the guide block 18. The inside of the sleeve 5 is provided with the guide groove 19 that is slidably connected to the guide block 18. By setting the guide block 18 and the guide groove 19, the sliding limit of the connecting seat 6 in the sleeve 5 is implemented. A support spring 20 is snapped between the connecting seat 6 and the sleeve 5. By setting the support spring 20, the connecting seat 6 is provided with the reverse support elastic force. The support spring 20 is made of corrosion-resistant metal. One end of the connecting seat 6 is hinged to the mounting block 7. The side of the mounting block 7 away from the connecting seat 6 is fixedly connected to the chuck 8. In this application, the chuck 8 is made of conductive metal. The storage seat 1, support seat 2, connecting block 4, sleeve 5, connecting seat 6 and mounting block 7 are all made of wear-resistant insulating plastic.
[0033] Brief description of usage: When in use, place the ceramic tube between the two chucks 8. Under the action of the two support springs 20, the connecting seat 6 drives the chucks 8 on the mounting block 7 to clamp the ceramic tube between the two chucks 8. Using an external resistance tester, clamp the two connecting clips of the resistance tester onto the two chucks 8 to perform an insulation test on the ceramic tube. After the test is completed, flip the hinge between the support seat 2 and the storage seat 1 to store it inside the storage seat 1. Flip the sleeve 5 at the hinge with the connecting block 4 so that it slides to the bottom of the storage groove 3. Flip the chuck 8 around the hinge between the mounting block 7 and the connecting seat 6 so that it is on top of the connecting seat 6. This completes the overall folding and storage, making it convenient for transportation and storage.

A chuck 8 is fixedly connected to the side of the mounting block 7 away from the connecting base 6. Limiting grooves 9 are formed on opposite sides of the two chucks 8. There are four limiting grooves 9. Adjusting screws 10 are rotatably connected inside the limiting grooves 9. (In this application, there are four adjusting screws 10; the threads of the two adjusting screws 10 in the same direction are consistent, and the threads of the two perpendicular adjusting screws 10 are...) (The adjusting screws 10 have opposite thread directions) The surface of the adjusting screws 10 is threaded with a fixing block 11, and an extension block 12 is fixedly connected to the fixing block 11. The surface of the extension block 12 is symmetrically equipped with sliding blocks 22. The inside of the limiting groove 9 is provided with a sliding groove 23 that slides and connects with the sliding block 22. By setting the sliding block 22 and the sliding groove 23, the movement of the extension block 12 is slidably limited. The inside of the chuck 8 is provided with a connecting groove 13. One end of each of the four adjusting screws 10 passes through the inside of the connecting groove 13 and is fixedly sleeved with a bevel gear 21 that meshes with each other. By setting the bevel gear 21, it is convenient to rotate one adjusting screw 10 and drive the other adjusting screws 10 to rotate at the same time.
[0036] Brief description of the usage process: When the adjusting screw 10 is rotated, under the action of the bevel gear 21, the four adjusting screws 10 rotate simultaneously. The fixing block 11 is driven by the adjusting screw 10 to move inside the limiting groove 9. Under the action of the fixing block 11, the extension block 12 is driven to move inside the limiting groove 9, so that the extension block 12 can be dislodged from inside the limiting groove 9, extending the diameter of the chuck 8, making it suitable for clamping and fixing more large-sized ceramic tubes, thus improving its applicability.
