Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gear quenching, specifically to a gear quenching device. Background Technology
[0002] Quenching is a heat treatment process. For steel, quenching involves heating the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), holding it at that temperature for a period of time to achieve complete or partial austenitization, and then rapidly cooling it at a rate greater than the critical cooling rate to below Ms (or isothermally near Ms) to induce a martensitic (or bainitic) transformation. Quenching is also commonly used to describe solution treatment or heat treatment processes involving rapid cooling in materials such as aluminum alloys, copper alloys, titanium alloys, and tempered glass.
[0003] Gears typically require quenching during machining. A gear quenching device, such as the one described in patent publication number CN219526713U, can perform quenching operations on multiple gears at once by clamping the gears to be quenched onto all gear fixtures on the chain. This allows for efficient quenching with the induction coil making way for the chain drive. The device is highly automated, efficient in quenching, and has comprehensive functions and strong practicality.
[0004] However, the chain of this device is prone to interference and instability with the tooling connection, resulting in poor induction hardening effect and low reliability. Utility Model Content

The left side of the upper connecting plate 14 is connected to the quenching induction coil 15. The water tank 1 contains cooling water. Each gear fixture 9 holds the corresponding gear to be quenched. With the support frame 3 fixing the rotary drive motor 4, the rotary drive motor 4 drives the drive gear 5 to rotate. The drive gear 5 meshes with the internal gear ring 10. The internal gear ring 10 drives the ring frame 8. The outer connecting frame 7 connects to the circular connecting sleeve 6 to rotate outside the connecting shaft 2. When moving, the hydraulic cylinder 12 acts on the telescopic rod 13 to be in the extended state.

After being in position, the hydraulic cylinder 12 acts on the telescopic rod 13 to retract. The upper connecting plate 14 connects to the quenching induction coil 15 to move downward. The quenching induction coil 15 acts on the gear in the gear fixture 9 to quench, and then enters the water in the water tank 1 for cooling.
[0024] It also includes a counterweight 16, with the right side of the upper connecting plate 14 connected to the middle left side of the counterweight 16; the counterweight 16 can balance the center of gravity of the upper connecting plate 14 at the top of the telescopic rod 13, preventing deviation and improving stability.
