Description

Technical Field

[0001] This utility model belongs to the field of gear processing technology, specifically an automatic gear quenching device. Background Technology

[0002] A gear is a toothed mechanical part that transmits power and changes the speed and direction of motion through the precise meshing of its teeth. Gear hardening is a key heat treatment process that involves heating the gear and then rapidly cooling it to make its surface as hard and wear-resistant as steel armor, while maintaining its internal toughness.

[0003] Currently, gears are generally quenched manually, which poses a risk of burns during the quenching process. Furthermore, manually placing the quenched gears into the cooling tank after quenching can easily result in damage due to accidental impacts. Additionally, the fixed height of the quenching coil limits the application of a single quenching device to gears of a single thickness, severely impacting quenching efficiency and compromising the quality of the finished gears. Therefore, an automatic gear quenching device needs to be designed. Summary of the Invention

[0004] To address the aforementioned issues, and to resolve the safety hazards of burns during gear quenching caused by the commonly used manual clamping method, as well as the risk of accidental damage from accidental collisions when manually placing the gears into the cooling tank after quenching, and the limitation that a single quenching device can only quench gears of a single thickness due to the fixed height of the quenching coil, which severely impacts quenching efficiency and makes it difficult to guarantee the quality of the finished gears, this invention provides an automatic gear quenching device. This device effectively achieves rapid and efficient gear quenching. Furthermore, the inclusion of a second linear drive component allows the device to quench gears of various sizes and provides automated cooling after quenching. The three first linear drive components and the gear-bearing component ensure that the gear handling, quenching, and cooling processes are independent and can occur simultaneously, thereby improving the quenching efficiency and guaranteeing the quality of the finished gears.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic gear quenching device, comprising a base support assembly, the base support assembly supporting a circumferential rotation assembly and a second linear drive assembly, the circumferential rotation assembly driving a first linear drive assembly and a gear bearing assembly to rotate circumferentially, the second linear drive assembly driving a gear quenching assembly to move linearly in the vertical direction, the first linear drive assembly driving a gear bearing assembly to move linearly in the vertical direction to adjust and complete the cooling operation after quenching of the gear, the gear bearing assembly carrying a gear to be quenched, the second linear drive assembly driving a gear quenching assembly to move linearly in the vertical direction to adjust, and the gear quenching assembly performing a quenching operation on the gear to be quenched carried on the gear bearing assembly.

[0006] The aforementioned automatic gear quenching device includes a support platform, a cooling groove on the upper surface of the support platform, a water inlet pipe inserted into the inner wall of the cooling groove, a drain pipe inserted into the inner wall of the bottom surface of the cooling groove, and a connecting plate provided on the outer wall of the bottom surface of the support platform.

[0007] The aforementioned automatic gear quenching device includes a servo motor in the circumferential rotation component. The servo motor is detachably connected to the outer wall of the bottom surface of the support platform. The output shaft of the servo motor is connected to one end of a rotating shaft, and the other end of the rotating shaft is detachably connected to a rotating plate. The upper surface of the rotating plate has a limit hole.

[0008] In the aforementioned automatic gear quenching device, the first linear drive component includes a first electro-hydraulic cylinder, which is detachably connected to the upper surface of a rotating plate. One end of a first hydraulic telescopic rod is slidably connected to the inner wall of the first electro-hydraulic cylinder, and the other end of the first hydraulic telescopic rod is provided with a horizontal plate. A limit rod is detachably connected to the upper surface of the horizontal plate, and the outer wall of the limit rod is slidably connected to the inner wall of the limit hole.

[0009] The aforementioned automatic gear quenching device includes a gear bearing assembly comprising a bearing rod, which is detachably connected to the upper surface of a horizontal plate. A bearing plate is provided at the upper end of the bearing rod, and a slot is formed on the upper surface of the bearing plate.

[0010] In the aforementioned automatic gear quenching device, the second linear drive component includes a vertical plate, which is detachably connected to the outer wall of the connecting plate. A side groove is provided on the outer wall of the vertical plate away from the support platform. A second electric hydraulic cylinder is detachably connected to the upper surface of the vertical plate. One end of a second hydraulic telescopic rod is slidably connected to the inner wall of the second electric hydraulic cylinder, and the other end of the second hydraulic telescopic rod is detachably connected to an end plate. A sliding hole and a through hole are provided on the inner wall of the side groove.

[0011] The aforementioned automatic gear quenching device includes a gear quenching component comprising a slider. The slider has a groove on its outer wall facing the vertical plate, and the inner wall of the groove is slidably connected to the inner wall of the sliding hole. A heating coil is provided on the outer wall of the slider away from the vertical plate, and a coil interface is provided on the inner wall of the groove. The heating coil is electrically connected to the coil interface.

[0012] In the aforementioned automatic gear quenching device, there are three first linear drive components and three gear bearing components, and the three first electro-hydraulic cylinders are evenly distributed on the upper surface of the rotating plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) First, select a gear bearing assembly of appropriate size according to the size of the gear to be quenched. Then, make a detachable connection between the bearing rod and the horizontal plate to fix the bearing plate above the horizontal plate. Next, wed the gear to be quenched and the inner side wall of the slot to make a locking connection between the gear to be quenched and the bearing plate. Then, drive the rotating shaft to rotate by the servo motor to drive the rotating plate to rotate, thereby rotating the gear to be quenched to the position below the heating coil. Then, the second electric hydraulic cylinder drives the second hydraulic telescopic rod to extend and slide, thereby driving the end plate to move along the vertical direction inside the side groove. The movement of the slider and heating coil vertically positions them to the desired location. An external power supply is then connected via the coil interface, allowing the gear to be quenched under the heating action of the coil. Simultaneously, the sliding action of the slider's outer wall along the inner wall of the sliding hole ensures the stability of the linear movement of the heating coil. This effectively enables the device to quickly and efficiently quench gears. Furthermore, the included second linear drive component allows the device to quench gears of various sizes, improving both safety and versatility.

[0014] (2) After the gear is quenched, the second hydraulic telescopic rod is extended and slid by the second electric hydraulic cylinder, which can drive the end plate to reset in the vertical direction. Then, the rotating shaft is driven by the servo motor, which can drive the rotating plate to rotate, and thus move the quenched gear to the position above the cooling tank. Then, the first hydraulic telescopic rod is extended and slid by the first electric hydraulic cylinder, which can drive the horizontal plate to move vertically into the cooling tank. The coolant in the cooling tank can then cool the quenched gear in time. The stability of the linear movement of the horizontal plate is ensured by the sliding action of the limit rod along the limit hole. At the same time, the water inlet pipe can add water to the cooling tank, and the drain pipe can drain the liquid in the cooling tank in time. This effectively realizes that the device has the function of timely automatic cooling after the gear is quenched. The gear picking and placing process, gear quenching process and gear cooling process are independent of each other and can be carried out simultaneously by the three first linear drive components and gear bearing components. This not only improves the gear quenching efficiency of the device, but also ensures the product quality of the finished gear. Attached Figure Description

[0021] Specifically, the gear bearing assembly 4 includes a bearing rod 401, which is detachably connected to the upper surface of the horizontal plate 303. A bearing plate 402 is provided at the upper end of the bearing rod 401, and a slot 403 is provided on the upper surface of the bearing plate 402.

Then, the gear to be quenched and the inner side wall of the slot 403 are wedged together to form a snap-fit ​​connection between the gear to be quenched and the bearing plate 402.

[0022] Specifically, the second linear drive assembly 5 includes a vertical plate 501, which is detachably connected to the outer wall of the connecting plate 105.

One end of a second hydraulic telescopic rod 504 is slidably connected to the inner wall of the second electric hydraulic cylinder 502. The other end of the second hydraulic telescopic rod 504 is detachably connected to an end plate 505. A sliding hole 506 and a through hole 507 are provided on the inner wall of the side groove 503. The second electric hydraulic cylinder 502 drives the second hydraulic telescopic rod 504 to extend and slide, thereby driving the end plate 505 to move vertically inside the side groove 503, which in turn drives the slider 601 and the heating coil 603 to fall to the desired position vertically.

[0023] Specifically, the gear quenching assembly 6 includes a slider 601. The slider 601 has a groove 602 on its outer wall facing the vertical plate 501, and the inner wall of the groove 602 is slidably connected to the inner wall of the sliding hole 506. A heating coil 603 is provided on the outer wall of the slider 601 away from the vertical plate 501, and a coil interface 604 is provided on the inner wall of the groove 602. The heating coil 603 is electrically connected to the coil interface 604. By connecting an external power supply along the coil interface 604, the gear to be quenched can be quenched under the heating action of the heating coil 603.

[0024] Specifically, there are three of each of the first linear drive assembly 3 and gear bearing assembly 4, and the three first electric hydraulic cylinders 301 are evenly distributed on the upper surface of the rotating plate 203. The gear picking and placing process, gear quenching process and gear cooling process are independent of each other and can be carried out simultaneously through the three first linear drive assemblies 3 and gear bearing assemblies 4.

[0025] This invention first selects a gear bearing assembly 4 of appropriate size according to the size of the gear to be quenched. Then, the bearing rod 401 is detachably connected to the horizontal plate 303 to fix the bearing plate 402 above the horizontal plate 303. Next, the gear to be quenched is wedged with the inner wall of the slot 403 to engage with the bearing plate 402. Then, the servo motor 201 drives the rotating shaft 202 to rotate, thereby driving the rotating plate 203 to rotate, and thus rotating the gear to be quenched to a position below the heating coil 603. Subsequently, the second electric hydraulic cylinder 502 drives the second hydraulic telescopic rod 504 to extend and slide, thereby driving the gear to be quenched to rotate. The end plate 505 moves vertically within the side groove 503, thereby driving the slider 601 and heating coil 603 to the desired position vertically. Then, an external power supply is connected via the coil interface 604, allowing the gear to be quenched under the heating effect of the heating coil 603. Simultaneously, the sliding action of the outer wall of the slider 601 along the inner wall of the sliding hole 506 ensures the stability of the linear movement of the heating coil 603, effectively realizing the device's function of rapid and efficient gear quenching. Furthermore, the included second linear drive component 5 enables the device to perform quenching operations on gears of various sizes, not only improving the device's performance... The device ensures safety and has high applicability. After the gear is quenched, the second electric hydraulic cylinder 502 drives the second hydraulic telescopic rod 504 to extend and slide, thereby resetting the end plate 505 vertically. Then, the servo motor 201 drives the rotating shaft 202 to rotate, which in turn drives the rotating plate 203 to rotate, thus moving the quenched gear to a position above the cooling tank 102. Finally, the first electric hydraulic cylinder 301 drives the first hydraulic telescopic rod 302 to extend and slide, thereby moving the horizontal plate 303 vertically into the cooling tank 102. The coolant inside the cooling tank 102 then quenches the gear. The device performs cooling operations in real time, and the stability of the linear movement of the horizontal plate 303 is ensured by the sliding action of the limiting rod 304 along the limiting hole 204. At the same time, the water inlet pipe 103 can add water to the inside of the cooling tank 102, while the drain pipe 104 can drain the liquid inside the cooling tank 102 in a timely manner. This effectively realizes the function of automatic cooling of the gears in a timely manner after quenching. Furthermore, the three first linear drive components 3 and the gear bearing components 4 enable the gear picking and placing process, the gear quenching process and the gear cooling process to be independent and carried out simultaneously. This not only improves the gear quenching efficiency of the device, but also ensures the product quality of the finished gears.
