[0002] A reducer is an independent component composed of a gear drive, a worm drive, and a gear-worm drive enclosed in a rigid housing, and is commonly used as a speed reduction drive device between a prime mover and a working machine. The internal transmission elements are supported and limited through the reducer box body and cover. The reducer box body and cover need to be quenched to improve their rigidity, hardness, wear resistance, fatigue strength, and toughness. During the quenching process of the reducer box body and cover, they are placed through a tooling device. For some quenching toolings, a tooling seat is used to place the reducer box body and cover. The reducer box body is placed on the upper side of the tooling seat, and the cover is aligned and stacked on the upper side of the box body. After the reducer box body and cover are quenched and heated, they need to be quickly cooled in a coolant. However, this method makes the reducer box body, cover, and tooling seat fit and contact with each other, reducing the quenching and cooling contact area of the reducer box body and cover, and there is room for improvement.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1 , this embodiment provides a technical solution: a quenching tooling for the box body and box cover of a reducer, including a quenching base 1;

[0019] Quenching base 1: A chute is provided on its upper side, and evenly distributed sliding seats 2 are slidably connected inside the chute. On one side of each sliding seat 2 close to the center of the quenching base 1, there is a box body clamp seat 5. The upper sides of the sliding seats 2 are all rotatably connected to a first screw rod 7 through bearings. The upper ends of the first screw rods 7 are all threadedly connected to a lifting and separating seat 8. On one side of each lifting and separating seat 8 close to the center of the quenching base 1, there is a threaded cylinder 11 rotatably connected through a bearing. Inside each threaded cylinder 11, there is a second screw rod 12 threadedly connected. At one end of each second screw rod 12 close to the center of the quenching base 1, there is a box cover clamp seat 13. Inside the chute, a bidirectional lead screw 3 is rotatably connected through a bearing. The sliding seats 2 are all threadedly connected to the bidirectional lead screw 3. A first turntable 4 is provided at the front end of the bidirectional lead screw 3. Guide rods 9 are provided on the upper sides of the sliding seats 2. The upper ends of the guide rods 9 are all slidably connected to the adjacent lifting and separating seats 8. On one side of each lifting and separating seat 8 close to the center of the quenching base 1, there are evenly distributed telescopic rods 14. The telescopic ends of the telescopic rods 14 are all fixedly connected to the adjacent box cover clamp seats 13. Second turntables 10 are provided at the upper ends of the first screw rods 7. Third turntables 15 are provided at one end of each threaded cylinder 11 away from the center of the quenching base 1. Evenly distributed suspended support seats 16 are provided on the upper side of the quenching base 1. The first screw rods 7 and the adjacent threaded cylinders 11 are vertically offset. When using the device to quench and fix the reducer box body and box cover, first align the reducer box body and box cover and horizontally place them on the upper side of the quenching base 1. Through the suspended support seats 16, the lower side of the reducer box body is separated from the upper side of the quenching base 1. Then rotate the first turntable 4 to drive the bidirectional lead screw 3 to rotate. The bidirectional lead screw 3 makes the sliding seats 2 drive the box body clamp seats 5 to move closer to the center of the device along the chute through threaded connection, so as to squeeze and fix the outer side of the reducer box body. Then rotate the front and rear third turntables 15 respectively. The third turntables 15 drive the threaded cylinders 11 to rotate. The threaded cylinders 11 make the second screw rods 12 drive the box cover clamp seats 13 to move closer to the center part of the device through threaded connection, so as to clamp and fix the side of the reducer box cover. During this process, the telescopic ends of the telescopic rods 14 adaptively expand and contract, so as to avoid the phenomenon of self-rotation during the longitudinal movement of the box cover clamp seats 13 and assist in supporting the box cover clamp seats 13 at the same time. Then rotate the second turntables 10 simultaneously to drive the first screw rods 7 to rotate. The first screw rods 7 make the lifting and separating seats 8 move vertically upward through threaded connection, so that the box cover clamp seats 13 drive the reducer box cover to move vertically upward to separate from the reducer box body. During this process, the lifting and separating seats 8 slide along the guide rods 9, so as to avoid self-rotation. By separating the reducer box body, box cover and quenching base 1, it enables the subsequent quenching process of the reducer box body and box cover to be in full contact with the coolant, improving the quenching and cooling speed of the reducer box body and box cover. The quenching tooling for the reducer box body and box cover can separate the reducer box body, box cover and quenching base 1 through transmission elements, avoiding contact, facilitating full contact with the coolant during the quenching and cooling process of the reducer box body and box cover, and accelerating the quenching and cooling speed;

[0020] Among them, evenly distributed reinforcing ribs 6 are provided between the box body clamp seat 5 and the adjacent sliding seat 2, and the strength of the box body clamp seat 5 itself is improved through the reinforcing ribs 6.

[0021] The working principle of a quenching tooling for a reducer box body and box cover provided by the present utility model is as follows: When using the device to fix the reducer box body and box cover during quenching, first align the reducer box body and box cover and horizontally place them on the upper side of the quenching seat 1. Through the suspended support seat 16, the lower side of the reducer box body is separated from the upper side of the quenching seat 1. Subsequently, rotate the first turntable 4 to drive the double - lead screw 3 to rotate. The double - lead screw 3 makes the sliding seat 2 drive the box body clamp seat 5 to move closer to the center of the device along the chute through threaded connection, so as to squeeze and fix the outer side of the reducer box body. Then, rotate the front and rear third turntables 15 respectively. The third turntable 15 drives the threaded cylinder 11 to rotate. The threaded cylinder 11 makes the stud two 12 drive the box cover clamp seat 13 to move closer to the center part of the device through threaded connection, so as to clamp and fix the side of the reducer box cover. During this process, the telescopic end of the telescopic rod 14 adaptively expands and contracts, so as to avoid the phenomenon of self - rotation during the longitudinal movement of the box cover clamp seat 13 and assist in supporting the box cover clamp seat 13 at the same time. Then, rotate the second turntable 10 simultaneously to drive the stud one 7 to rotate. The stud one 7 makes the lifting and separating seat 8 move vertically upward through threaded connection, so that the box cover clamp seat 13 drives the reducer box cover to move vertically upward to separate from the reducer box body. During this process, the lifting and separating seat 8 slides along the guide rod 9, so as to avoid the phenomenon of self - rotation. The strength of the box body clamp seat 5 itself is improved through the reinforcing ribs 6. By separating the reducer box body, box cover and the quenching seat 1, the subsequent quenching process of the reducer box body and box cover can be in full contact with the coolant, and the quenching and cooling speed of the reducer box body and box cover can be increased.
