Description

Technical Field

[0001] This utility model relates to the field of thermocouple testing technology, specifically to a novel tooling for thermocouple production and testing. Background Technology

[0002] Thermocouple testing focuses on accuracy, stability, and response speed. It employs professional equipment and methods, strictly controls quality, and ensures accurate and reliable temperature measurement to meet application requirements.

[0003] When using a thermocouple testing furnace, the thermocouple temperature becomes extremely high after the testing process, making it inconvenient and posing a safety hazard to remove it directly from the fixture. Traditional thermocouple production and testing tooling designs have limitations; after testing each thermocouple, it must be removed and a new thermocouple must be clamped before the testing process can continue. This not only significantly increases the difficulty and intensity of the operator's work but also greatly reduces testing efficiency. Therefore, a new type of thermocouple production and testing tooling is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that traditional thermocouple production and testing tooling has limitations, requiring the removal of a thermocouple and the clamping of a new thermocouple after each test before the testing process can continue. This utility model provides a new type of thermocouple production and testing tooling.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A novel tooling for thermocouple production and testing includes a thermocouple testing furnace. The bottom of the thermocouple testing furnace is fixedly installed with two support legs. The outer sides of the two support legs are provided with slidable and adjustable slide rod assemblies. The slide rod assemblies are provided with telescopically adjustable lifting rod assemblies. The lifting rod assemblies are provided with rotating components that can rotate 90 degrees. The rotating components are provided with two sets of clamping components for clamping thermocouples.

[0006] Furthermore, the slide rod assembly includes slide rods, with slide rods respectively provided on both sides of the support leg. The sides of the two slide rods that are close to each other are respectively provided with convex grooves. A convex rod is movably installed inside each convex groove. Each convex rod is fixedly connected to the two support legs. A linkage rod is fixedly installed at the front end of the two slide rods. Bending rods are fixedly installed on both sides of the thermocouple identification furnace. A bolt is threaded to the vertical end of each bending rod. An anti-slip pad is fixedly connected to the tail end of each bolt.

[0007] Furthermore, the lifting rod assembly includes a square tube, the top of the linkage rod is fixedly installed with the square tube, the lifting rod is movably installed inside the square tube, the side wall of the square tube has a strip hole, the side wall of the lifting rod is fixedly installed with a lead screw that passes through the strip hole, and a nut is threaded onto the lead screw.

[0008] Furthermore, the lifting rod assembly also includes elongated holes. Elongated holes are respectively opened on both sides of the square tube. A slider is movably installed inside each elongated hole, and each slider is fixedly connected to the lifting rod.

[0009] Furthermore, the rotating assembly includes a U-shaped block, a U-shaped block is fixedly installed at the top of the lifting rod, a right-angle rod is movably installed inside the U-shaped block, an arc-shaped hole is opened on the side wall of the U-shaped block, a fan-shaped block is movably installed inside the arc-shaped hole, the fan-shaped block is fixedly connected to the U-shaped block, a threaded rod is fixedly installed on the side wall of the fan-shaped block, and a nut is threaded onto the threaded rod.

[0010] Furthermore, the clamping assembly includes a U-shaped frame, with U-shaped frames fixedly installed at both ends of the U-shaped block. A bidirectional lead screw is movably installed inside each U-shaped frame, and a moving block is threaded to both ends of each bidirectional lead screw. A limit hole is opened on the bottom surface of the inside of each U-shaped frame, and a limit block is fixedly installed at the bottom of each moving block. Each limit block is movably installed inside an adjacent limit hole. A handwheel for rotating adjacent bidirectional lead screws is movably installed on the side wall of each U-shaped frame. A clamping block is fixedly installed on the top of each moving block, and an arc-shaped groove is opened on the side of each pair of adjacent clamping blocks that are close to each other.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model uses two sets of clamping components to fix two thermocouples. After the lifting rod assembly is adjusted to a suitable height and the thermocouple testing furnace is heated, the sliding rod assembly is pushed to bring the lifting rod assembly closer to the thermocouple testing furnace, allowing one thermocouple to be inserted into the furnace and the other to be placed to the side of the thermocouple testing furnace. After the thermocouple in the furnace is tested, the sliding rod assembly is pushed to move the lifting rod assembly away from the thermocouple testing furnace, and the tested thermocouple is pulled out. Since the surface temperature of the thermocouple that has just been tested is high and it is inconvenient to remove it, the rotating assembly is adjusted to drive the clamping assembly to rotate 90 degrees, so that the other thermocouple is aligned with the furnace opening, and the sliding rod assembly is pushed again to continue testing. The tested thermocouple can be cooled naturally or by air. Attached Figure Description

[0017] like Figure 1-4As shown, a novel fixture for thermocouple production and testing includes a thermocouple testing furnace 1. Two support legs 2 are fixedly mounted on the bottom of the thermocouple testing furnace 1, and adjustable sliding rod assemblies 3 are provided on the outer sides of the two support legs 2. Figure 1 As shown, specifically, the slide rod assembly 3 includes a slide rod 301. Slide rods 301 are respectively provided on both sides of the support leg 2. A convex groove 302 is opened on the side of the two slide rods 301 that are close to each other. A convex rod 303 is movably installed inside each convex groove 302. Each convex rod 303 is fixedly connected to the two support legs 2. A linkage rod 304 is fixedly installed at the front end of the two slide rods 301. Bending rods 305 are fixedly installed on both sides of the thermocouple identification furnace 1. A bolt 306 is threadedly connected to the vertical end of each bending rod 305. An anti-slip pad 307 is fixedly connected to the tail end of each bolt 306.

[0018] More specifically, the convex rod 303 is fixed on the support leg 2 and forms a precision guide rail with the convex groove 302 of the slide rod 301, ensuring that the slide rod assembly 3 can only move linearly back and forth; the linkage rod 304 rigidly connects the two slide rods 301 to achieve synchronous sliding; after the bolt 306 on the bending rod 305 is tightened, the anti-slip pad 307 presses against the side of the slide rod 301 to form a friction lock, which can be quickly fixed in any position.

[0019] The slide rod assembly 3 is equipped with a telescopically adjustable lifting rod assembly 4, such as... Figure 1 , 2 As shown, specifically, the lifting rod assembly 4 includes a square tube 401, the top of the linkage rod 304 is fixedly installed with the square tube 401, the lifting rod 402 is movably installed inside the square tube 401, the side wall of the square tube 401 is provided with a strip hole 403, the side wall of the lifting rod 402 is fixedly installed with a lead screw 404 that passes through the strip hole 403, and a nut 405 is threaded onto the lead screw 404.

[0020] The lifting rod assembly 4 also includes an elongated hole 406. The square tube 401 has elongated holes 406 on both sides. A slider 407 is movably installed inside each elongated hole 406. Each slider 407 is fixedly connected to the lifting rod 402.

[0021] More specifically, the lifting rod 402 slides up and down inside the square tube 401, and the lead screw 404 passes through the strip hole 403 and moves synchronously with the rod. When the height is determined, the nut 405 is tightened, and the friction force generated by the surface contact between the lead screw 404 and the wall of the square tube 401 is used to lock the lifting rod 402.

[0022] The slider 407 is fixedly connected to the lifting rod 402 and slides within the elongated hole 406, forming a double-sided guide to prevent the lifting rod 402 from wobbling or misaligning when moving up and down.

[0023] The lifting rod assembly 4 is equipped with a rotating component 5 that can rotate 90 degrees, such as... Figure 1-3 As shown, specifically, the rotating assembly 5 includes a U-shaped block 501, the top end of the lifting rod 402 is fixedly installed with the U-shaped block 501, a right-angle rod 502 is movably installed inside the U-shaped block 501, an arc-shaped hole 503 is opened on the side wall of the U-shaped block 501, a fan-shaped block 504 is movably installed inside the arc-shaped hole 503, the fan-shaped block 504 is fixedly connected to the U-shaped block 501, a threaded rod 505 is fixedly installed on the side wall of the fan-shaped block 504, and a nut 506 is threadedly connected to the threaded rod 505.

[0024] More specifically, the right-angle rod 502 rotates horizontally within the U-shaped block 501, and the fan-shaped block 504 and the arc-shaped hole 503 provide a 90-degree rotation range; when rotated to the position, the threaded rod 505 and the nut 506 form an end face lock, fixing the right-angle rod 502 at the current angle, ensuring that the clamping assembly 6 can quickly switch between the furnace opening and the standby position.

[0025] The rotating assembly 5 is equipped with two sets of clamping assemblies 6 for holding thermocouples, such as... Figure 1-4 As shown, specifically, the clamping assembly 6 includes a U-shaped frame 601, with U-shaped frames 601 fixedly installed at both ends of the U-shaped block 501. A bidirectional lead screw 602 is movably installed inside each U-shaped frame 601, and a moving block 603 is threaded to both ends of each bidirectional lead screw 602. A limiting hole 604 is opened on the bottom surface of the inside of each U-shaped frame 601. A limiting block 605 is fixedly installed at the bottom of each moving block 603. Each limiting block 605 is movably installed inside the adjacent limiting hole 604. A handwheel 606 for rotating the adjacent bidirectional lead screw 602 is movably installed on the side wall of each U-shaped frame 601. A clamping block 607 is fixedly installed on the top of each moving block 603. An arc-shaped groove 608 is opened on the side of each pair of adjacent clamping blocks 607 that are close to each other.

[0026] More specifically, the handwheel 606 drives the bidirectional lead screw 602 to rotate, and the two moving blocks 603 can only move in a straight line and center under the constraint of the limiting hole 604 and the limiting block 605, so that the arc groove 608 of the clamping block 607 can simultaneously clamp or release the thermocouple protection tube.

[0027] In summary: First, two sets of clamping assemblies 6 are used to fix two thermocouples respectively, and the lifting rod assembly 4 is extended and retracted to a suitable height. Then, after the thermocouple testing furnace 1 is heated, the sliding rod assembly 3 is pushed to make the lifting rod assembly 4 gradually approach the thermocouple testing furnace 1, so that one thermocouple can be inserted into the thermocouple testing furnace 1, and the other thermocouple is placed to the side of the thermocouple testing furnace 1. After the thermocouple inside the thermocouple testing furnace 1 has been tested, the sliding rod assembly 3 is pushed to make the lifting rod assembly 4 gradually move away from the thermocouple testing furnace 1. At this time, the thermocouple that has been tested is complete. The thermocouple will be extracted from inside the thermocouple testing furnace 1. Since the surface temperature of the thermocouple that has just been tested is high and it is not convenient to remove it, the staff can adjust the rotating component 5 to drive the clamping component 6 to rotate 90 degrees so that the other thermocouple is aligned with the furnace opening. Then, push the sliding rod component 3 to make the lifting rod component 4 gradually approach the thermocouple testing furnace 1, and the testing process can continue. The thermocouple that has just been tested can be placed on the side of the thermocouple testing furnace 1 to cool naturally or borrow an external air cooling tool to cool it quickly, avoiding the problem of the staff having to disassemble it under high temperature.
