Description

Technical Field

[0001] The present invention relates to the technical field of thermocouple compensating wire processing, and specifically relates to a wire threading device for thermocouple compensating wires that improves measurement accuracy. Background Technique

[0002] Thermocouple compensating wire is a special wire that plays an electrical connection role between the thermocouple and the measuring device. The working end of the thermocouple is usually in a high-temperature environment, while the measuring instrument is generally in a normal-temperature environment. The compensating wire can extend the cold end of the thermocouple to a place with relatively stable temperature, which is convenient for measurement and control. Since the output electromotive force of the thermocouple is related to the cold-end temperature, when the cold-end temperature changes, a measurement error will occur. The compensating wire can use the same material as the thermocouple or a material with similar thermoelectric characteristics to compensate for the influence caused by the change of the cold-end temperature to a certain extent.

[0003] The patent application with the application number CN202320805777.X discloses a wire threading device for thermocouple compensating wires, including a machine body. A winding mechanism is fixedly connected to the top of the machine body, a fixing frame is fixedly connected to the top of the machine body, and a unwinding mechanism is fixedly connected to the top of the machine body.

[0004] The wire threading device for thermocouple compensating wires is a tool used in the installation process of thermocouple compensating wires. Its main function is to assist in the wire threading operation of the compensating wire. When the existing equipment is used, there is a lack of positioning for the wire threading, which makes it easy for the wire to fail to enter the pipeline during the use of the equipment, resulting in malfunctions of the equipment and affecting the normal wire threading operation of the equipment. Summary of the Invention

[0005] The purpose of the present invention is to provide a wire threading device for thermocouple compensating wires that improves measurement accuracy, so as to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: A wire threading device for a thermocouple compensating wire to improve measurement accuracy, including a base. A placement rack is fixedly connected to the top of the base. A ramp plate is fixedly connected to the front end of the base. By setting the ramp plate, the hollow column after the wire threading operation can be placed on the ramp plate.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0016] 1.

By setting a linkage mechanism in the present invention, after the device completes the movement of the hollow tube, under the action of the linkage component, the guiding mechanisms and the wire outlet mechanisms on both sides will move towards the hollow tube, starting the clamping and fixing effect on the hollow tube and completing the positioning of the hollow tube, ensuring that the guiding component can extend the connecting column into the hollow tube and ensuring the stable operation of the device.

[0018] 3. By setting a guiding mechanism in the present invention, when the guiding mechanism extends the circular plate into the wire outlet mechanism, it will automatically clamp and fix the wire. As the guiding mechanism pulls out the wire and resets the circular plate, it will automatically release the fixation of the wire. Such a setting can ensure that the wire passes through the hollow tube. At the same time, due to the guiding component passing through the hollow tube, it can avoid the deformation caused by the overlong extension of the connecting column and ensure the normal operation of wire threading of the device.

[0019] 4. By setting a wire outlet mechanism in the present invention, after the device completes wire threading, it will cut a part of the wire. After the cutting is completed, the wire will be retracted backward by a certain distance, which can reduce the length of the wire extending outward and avoid the overlong extension of the wire, resulting in the wire not being in a horizontal state. Ensure that the wire can be embedded in the circular plate during the next wire threading, improving the stability of the device operation. Description of the Drawings

[0040] The working principle of this embodiment is as follows: When the device is running, the hollow tube is pushed into the placement rack 101 by the feeding device 108.

A bracket 304 is fixedly connected to the top of the first sliding plate 302. An annular plate 305 is fixedly connected to the top of the bracket 304. By providing the annular plate 305, when the motor 308 and the threaded column 306 drive the connecting column 3010 to reset, as the device passes the wire through the hollow tube, the annular plate 305 will also contact the movable column 3020 and squeeze the movable column 3020 to move forward. The forward-moving movable column 3020 pushes the force-bearing column 3017 on the second movable plate 3016 to leave the fourth notch 3021 and fit against the outer wall of the movable column 3020. In this way, with the support of the movable column 3020 for the force-bearing column 3017, the second fixing plate 3018 will also release the fixation of the wire. The inner wall of the first sliding plate 302 is rotatably connected to a threaded column 306 through a bearing. The outer wall of the first sliding plate 302 is fixedly connected to a motor 308.

[0042] The working principle of this embodiment is as follows: when the device needs to pass the wire through the hollow tube, it is necessary to first drive the connecting column 3010 to pass through the hollow tube and fix the wire in the wire outlet mechanism 4. After the fixation is completed, the wire is dragged through the hollow tube.

At the same time, the movable column 3020 will be squeezed by the connecting frame 403 and move backward. At this time, the force column 3017 on the movable plate 3016 will be aligned with the notch 3021, so that the movable plate 3016 loses support, so that the fixed plate 3018 clamps the wire under the elastic force of the spring 3019. After the clamping is completed, the connecting column 3010 is driven to reset by the motor 308 and the threaded column 306 to complete the threading operation.
