Description

Technical Field

[0001] This utility model relates to the field of internal gear ring processing technology, specifically to a tooling for surface strengthening treatment of internal gear rings. Background Technology

[0002] The internal gear ring is the core component of the planetary gear transmission system. Its ring-shaped internal gear structure is coaxial with the planet carrier. Its outer surface is smooth and its inner ring has involute tooth profile. As a basic component of the planetary gear system, the internal gear ring realizes power transmission, speed regulation and rotation direction change through internal meshing with the planetary gears. It plays a key transmission function in wind power equipment and engine starting systems.

[0003] Internal gear rings are widely used in automotive transmissions and synchronizers. In actual use, they often bear large torques. To meet the strength requirements of internal gear rings, they often need to be strengthened. Traditional strengthening processes often involve heating individual gears with lasers or through inductive heating. Laser heating is slow, which affects rapid production. While inductive heating provides rapid cooling after heating, the surface temperature remains high. Traditional material handling is often done manually, which may result in burns from residual heat and cannot meet production needs. Summary of the Invention

[0029] Example

[0030] The surface strengthening tooling for the internal gear ring provided in this embodiment, such as... Figures 1-7 As shown, the system includes a base 1, a quenching liquid container 2 fixedly mounted on the top of the base 1, a second L-shaped mounting rod 4 fixedly mounted on the top of the base 1 and behind the quenching liquid container 2, a discharge mechanism 6 provided on the front side of the second L-shaped mounting rod 4, an mounting plate 11 provided inside the quenching liquid container 2, a placement plate 12 provided above the mounting plate 11, three evenly distributed support blocks 13 fixedly mounted on the top of the placement plate 12, an mounting strip 15 provided below the second L-shaped mounting rod 4, and an inductor coil 8 fixedly mounted at the bottom of the mounting strip 15. The quenching liquid container 2 is used to accommodate and install the mounting plate 11 and the placement plate 12, and to store the quenching liquid. The second L-shaped mounting rod 4 is used to install the discharge mechanism 6, which is used to push out the internal gear ring that has been heated and quenched and placed on the top of the support block 13 to avoid the problem of burns caused by manual handling.

[0031] The material discharge mechanism 6 includes a second electric push rod 601 fixedly installed on the rear side of the second L-shaped mounting rod 4. The output end of the second electric push rod 601 passes through the second L-shaped mounting rod 4 and is fixedly installed with a push block 602. A circular groove 603 is provided on the front side of the push block 602. The second electric push rod 601 is provided to push the push block 602 to move. The push block 602 and the circular groove 603 push out the inner toothed ring on the top of the support block 13.

[0032] A third electric push rod 9 is fixedly installed at the bottom of the base 1. The output end of the third electric push rod 9 passes through the base 1 and extends into the interior of the quenching liquid holding tank 2. A U-shaped mounting bracket 10 is fixedly installed inside the quenching liquid holding tank 2 at the output end of the third electric push rod 9. The top of the U-shaped mounting bracket 10 is fixedly connected to the bottom of the mounting plate 11. The third electric push rod 9 and the U-shaped mounting bracket 10 are used to realize the lifting and lowering of the mounting plate 11, the placement plate 12, the support block 13 and the internal gear ring placed on the top of the support block 13, so that the internal gear ring can descend into the interior of the quenching liquid holding tank 2 after being heated by the inductor coil 8, so that it can be quenched by the quenching liquid.

[0033] A waterproof drive motor 14 is fixedly installed at the bottom of the mounting plate 11. The output end of the waterproof drive motor 14 passes through the mounting plate 11 and is fixedly connected to the bottom of the placement plate 12. The waterproof drive motor 14 is used to drive the placement plate 12, the support block 13 and the internal gear ring to rotate, thereby enabling the internal gear ring to be uniformly heated by the inductor coil 8.

[0034] The top of the second L-shaped mounting rod 4 is fixedly mounted with a first electric push rod 5. The output end of the first electric push rod 5 passes through the second L-shaped mounting rod 4 and is fixedly connected to the top of the mounting strip 15. The first electric push rod 5 is used to drive the mounting strip 15 and the inductor coil 8 to descend, so that the inductor coil 8 passes through the interior of the internal gear ring for heating.

[0035] A guide plate 7 is fixedly installed on the top of the quenching liquid holding tank 2. The bottom of the guide plate 7 extends forward and slopes downward. The guide plate 7 is used to discharge the internal gear ring pushed out by the discharge mechanism 6 after heating and quenching, so as to facilitate subsequent collection.

[0036] Two first L-shaped mounting rods 3 are fixedly installed on the top of the quenching liquid holding tank 2. A limit ring 16 is fixedly installed between the first L-shaped mounting rods 3. The limit ring 16 is located directly above the placement plate 12. The first L-shaped mounting rods 3 are used to install the limit ring 16. The limit ring 16 is used to lower the internal gear ring placed on the top of the support block 13 to prevent the internal gear ring from shifting during rotation and affecting the subsequent heating of the inductor coil 8.

[0037] The pusher block 602 is located above the support block 13. The diameter of the inductor coil 8 is smaller than the diameter between the support blocks 13. The circular groove 603 is placed above the support block 13 to prevent it from touching the support block 13 when pushing the processed internal gear ring. The diameter of the inductor coil 8 is set to be smaller than the distance between the support blocks 13 so that the inductor coil 8 can completely penetrate the internal gear ring, thereby achieving complete heating of the thicker internal gear ring.

[0038] In use, quenching fluid, including but not limited to water or oil, is injected into the quenching fluid container 2. The internal gear ring to be heated is placed on top of the support block 13. The third electric push rod 9 pushes the U-shaped mounting bracket 10, causing the mounting plate 11, support block 13, and internal gear ring to rise, so that the internal gear ring is located inside the limit ring 16. After the lifting and lowering is completed, the first electric push rod 5 pushes the inductor coil 8 to descend, so that the inductor coil 8 penetrates to the inside of the internal gear ring. After penetration, the internal gear ring is heated by the inductor coil 8. At the same time, the waterproof drive motor 14 drives the placement plate 12 to rotate, causing the support block 13 and internal gear ring to rotate so that they can be fully heated by the inductor coil 8. After heating, the inductor coil 8 is lifted by the first electric push rod 5. At the same time, the U-shaped mounting bracket 10 is driven by the third electric push rod 9 to move the placement plate 12, support block 13 and internal gear ring into the quenching liquid holding tank 2, so that the internal gear ring is immersed in the quenching liquid for quenching. After quenching, the third electric push rod 9 pushes the U-shaped mounting bracket 10 to raise the mounting plate 11 and support block 13, so that the top of the support block 13 is on the same plane as the top of the guide plate 7. The second electric push rod 601 pushes the push block 602 to push the quenched internal gear ring on the top of the support block 13 to the top of the guide plate 7, and then it is discharged through the guide plate 7.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
