Abstract
Description
Technical Field
[0001] This utility model relates to the field of induction hardening technology, specifically to an anti-splash quenching induction processing device for gear shaft parts. Background Technology
[0002] During the induction hardening process of gear shaft parts, the gear shaft is fixed by the upper and lower centers of the hardening machine tool. The hardening inductor then hardens the gear shaft. After hardening, a water spray ring sprays out the hardening medium for cooling. However, due to the limited space in the machining area, the hardening medium sprayed onto the parts can easily splash outside the hardening machine tool, onto workers, and into the workshop. This not only pollutes the working environment but also wastes the hardening medium and reduces the hardening effect.
[0003] To address the splashing issue, an isolation cover is currently installed outside the quenching machine, isolating it as an independent processing station. A sliding window is installed on one side of the isolation cover. During cooling, the operator closes the window to prevent the quenching medium from splashing outside the isolation cover. After cooling is complete, the window is opened to remove the part and replace it with the next part to be processed. However, in actual operation, repeatedly closing and opening the sliding window is time-consuming and laborious, and operators are reluctant to close and open the window to prevent splashing, so the splashing problem still exists. Summary of the Invention
[0004] To overcome the shortcomings of the prior art, this utility model provides an anti-splash quenching induction machining device for gear shaft parts.
[0005] To achieve the above objectives, an anti-splash quenching induction machining device for gear shaft parts is designed, including a worktable. The upper end of the worktable is connected to the lower center via a connecting seat. A support frame is provided on one side of the worktable, and an upper center is connected to the support frame via a connecting rod. The upper center is located directly above the lower center. The area between the upper and lower centers is the part mounting area. A quenching sensor is provided behind the part mounting area. A water spray ring is provided outside the part mounting area, and baffles are provided on both sides of the upper end of the water spray ring.
[0006] The upper end of the baffle is provided with an electric push rod, and the other end of the electric push rod is fixed to the connecting rod.
[0007] The baffle plate has a planar structure on the side near the quenching sensor, and a through hole is provided on the inner side of the baffle plate for the part to pass through. The shape of the outer edge of the baffle plate matches the shape of the water spray ring.
[0008] One end of the baffle is rotatably connected to the water spray ring via a rotating shaft.
[0009] The quenching inductor has a sensing area at its front end, which is located in the part mounting area during quenching.
[0010] The inner side of the spray ring is provided with several spray holes, and the outer side is provided with several water pipes that communicate with the spray holes.
[0011] Compared with existing technologies, this invention improves upon existing quenching equipment, making it easier to process and simpler in structure. The operation of closing and opening the baffle is simple, reducing the impact of quenching medium splashing on the surrounding environment, improving the quenching cooling effect, and ensuring product quality.

[0018] The present invention will be further described below with reference to the accompanying drawings. Example 1
[0019] like Figures 1 to 6 As shown, the upper end of the workbench 1 is connected to the lower center 3 via the connecting seat 2. A support frame 4 is provided on one side of the workbench 1. The upper center 5 is connected to the support frame 4 via the connecting rod 11. The upper center 5 is located directly above the lower center 3. The part mounting area 6 is between the upper center 5 and the lower center 3. A quenching sensor 7 is provided on the rear side of the part mounting area 6. A water spray ring 8 is provided on the outer side of the part mounting area 6. Baffles 9 are provided on both sides of the upper end of the water spray ring 8.
[0020] The baffle 9 has a planar structure 9-1 on the side near the quenching inductor 7, and a through hole 9-2 for the part to pass through on the inner side of the baffle. The shape of the outer edge of the baffle 9 matches the shape of the water spray ring 8.
[0021] One end of the baffle 9 is rotatably connected to the water spray ring 8 via the rotating shaft 12, which facilitates opening and closing the baffle 9.
[0022] The front end of the quenching inductor 7 is provided with a sensing area 7-1. During quenching, the sensing area 7-1 is located in the part mounting area 6 and the quenching operation is performed on the part placed in the part mounting area 6.
[0023] The inner side of the water spray ring 8 is provided with several water spray holes, and the outer side is provided with several water pipes 8-1 that are connected to the water spray holes. In actual use, the water pipes 8-1 are connected to the quenching medium source, and the quenching medium is sprayed onto the parts to be cooled through the water pipes and water spray holes.
[0024] In use, the operator places the gear shaft to be processed in the parts mounting area 6, and fixes the gear shaft using the upper center 5 and lower center 3. Then, the baffle 9 is closed, the quenching sensor 7 is activated, and the gear shaft undergoes quenching. After quenching, cooling medium is sprayed from the spray holes of the water spray ring 8 to cool the gear shaft. After cooling, the operator opens the baffle 9, removes the processed gear shaft, and places the next gear shaft to be processed.
[0025] During the cooling process, the spray ring 8 sprays out the cooling medium, while the baffle 9 blocks the sprayed cooling medium to prevent it from splashing out. Cooling medium that splashes onto the baffle 9 is returned to the gear shaft surface by the action of the baffle 9, thus cooling the gear shaft. Example 2
[0026] This embodiment only describes the differences from Embodiment 1; the similarities will not be repeated.
[0027] The difference between this embodiment and Embodiment 1 is that, Figures 1 to 2 As shown, in this embodiment, the upper end of the baffle 9 is provided with one end of an electric push rod 10, and the other end of the electric push rod 10 is fixed on the connecting rod 11.
[0028] In practical use, when a large amount of quenching medium is sprayed out, it is easy for the baffle 9 to be sprayed open before the cooling is finished, reducing the anti-splashing effect. Therefore, in this embodiment, an electric push rod 10 is provided at the upper end of the baffle 9 to press the baffle 9 and prevent it from being sprayed open before the cooling is finished. After the cooling is finished, the electric push rod 10 retracts, and the baffle 9 can be opened to remove the machined part.
