Abstract
Description
Technical Field
[0001] This utility model application relates to the technical field of temperature detection devices, specifically a portable temperature detection device for an ion nitriding furnace. Background Technology
[0002] Ion nitriding oxidation involves placing the metal workpiece as the cathode and the furnace as the anode within a low-vacuum furnace filled with nitrogen-containing gas. When electricity is applied, nitrogen and hydrogen atoms in the medium are ionized under a high-voltage DC electric field, forming a plasma region between the cathode and anode. Under the strong electric field of this plasma region, nitrogen and hydrogen ions bombard the workpiece surface at high speed. The high kinetic energy of the ions is converted into heat energy, heating the workpiece surface to the desired temperature. Due to the ion bombardment, atomic sputtering occurs on the workpiece surface, resulting in purification. Simultaneously, nitrogen penetrates the workpiece surface through adsorption and diffusion. This process is widely used in many fields such as automobiles, machinery, precision instruments, extrusion molding machines, and molds. Existing portable temperature detection devices for ion nitriding furnaces can move horizontally and vertically to ensure comprehensive detection. However, this movement occupies a significant amount of internal furnace space, limiting the space available for placing the workpiece and reducing the practicality of the temperature monitoring device.

Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0019] Reference Figure 1 , Figure 2 and Figure 3 A movable temperature detection device for an ion nitriding furnace includes a temperature detector 1, which is fixed to the inner wall of a support ring plate 2. A lifting screw 3 is provided on the side of the support ring plate 2. The upper and lower ends of the lifting screw 3 are rotatably connected to a fixed plate 4 via bearings. A servo motor 5 is provided on the top surface of the upper fixed plate 4. The output end of the servo motor 5 rotates through the fixed plate 4 and is fixed to the top surface of the lifting screw 3. A movable sleeve 6 is threaded onto the lifting screw 3. A support plate 7 is fixed to the side of the movable sleeve 6. The end of the support plate 7 away from the lifting screw 3 is fixed. There is a connecting side plate 8, and a supporting slider 9 is fixed at the end of the connecting side plate 8 away from the supporting plate 7. The supporting slider 9 is slidably sleeved in the groove 10 opened in the supporting ring plate 2. The supporting plate 7 and the supporting ring plate 2 are rotatably connected. A servo cylinder 14 is provided on the top surface of the supporting plate 7. The output end of the servo cylinder 14 rotates through to the bottom of the supporting plate 7 and a gear 13 is fixed thereon. A connecting ring plate 11 is fixed on the bottom surface of the supporting ring plate 2 on the side of the gear 13. Several teeth 12 are fixed at equal intervals on the outer surface of the connecting ring plate 11. The gear 13 is meshed with the teeth 12.
[0020] Specifically, when the temperature detector 1 needs to be moved, the servo motor 5 drives the lifting screw 3 to rotate. When the lifting screw 3 rotates, it drives the moving sleeve block 6 to move up and down. At the same time, the servo cylinder 14 drives the gear 13 to rotate. When the gear 13 rotates, it drives the meshing teeth 12 to rotate. When the teeth 12 rotate, they drive the connecting ring plate 11 to rotate. This drives the support ring plate 2 to rotate through the connecting ring plate 11. When the support ring plate 2 rotates, it moves on the support slider 9 through the slide groove 10, thereby driving the temperature detector 1 to perform up-and-down and circumferential detection inside the furnace.
[0021] As an optimized solution, the support ring plate 2 is set as an annular shape, the movable sleeve block 6 has a threaded hole inside that mates with the lifting screw 3, and both fixed plates 4 have fixed holes. An auxiliary sleeve block 15 is fixed on the side of the servo motor 5 away from the temperature detector 1. A limit slide rod 16 is slidably connected inside the auxiliary sleeve block 15. The upper and lower ends of the limit slide rod 16 are fixed on the fixed plate 4. The slide groove 10 is set as an annular shape that mates with the support ring plate 2. The cross-sections of the support slider 9 and the slide groove 10 are both convex shapes placed horizontally. The connecting side plate 8 and the support slider 9 are both set as arc shapes that mate with the support ring plate 2.
[0022] Specifically, when the movable sleeve 6 moves, it drives the auxiliary sleeve 15 to slide on the limit slide bar 16. When using the temperature detector 1, the lifting screw 3 can be installed inside the furnace body through the fixing plate 4.
