Description

Technical Field

[0001] The utility model relates to the technical field of gear processing and quenching, in particular to a gear processing and quenching device for a speed reducer gear. Background Art

[0002] The speed reducer gear is a key component used in a speed reducer (also known as a reduction gearbox), which is used to achieve the deceleration and torque increase of a mechanical system. The speed reducer is usually used in various mechanical transmission systems. By converting the high-speed rotation of an electric motor or other power source into a low-speed, high-torque output, the operation requirements of the equipment can be met. During the processing of the speed reducer gear, a quenching device is required to quench the gear to increase the hardness of the gear surface so that it can withstand high stress and high load.

[0003] When using a quenching device to quench a speed reducer gear, first, the gear needs to be installed on the upper part of the quenching platform, and then the gear is placed in the middle of the induction coil. Through the magnetic field generated by the high-frequency current, the induction coil heats the surface of the gear to complete the quenching operation.

[0004] However, although the existing quenching devices can complete the quenching operation of the speed reducer gear, the gear is not easy to rotate during the quenching process. Since the gear cannot rotate, local overheating or insufficient heating will occur during the heating process. Uneven heating will cause the hardness and wear resistance of the gear to be unevenly distributed, which will in turn affect the overall performance and service life of the gear.

[0028] Refer to Figures 1-5, an embodiment provided by the present utility model: a processing and quenching device for a reducer gear, including a cooling tank 1, a mounting frame 3 is fixedly connected to the rear side of the outside of the cooling tank 1, a quenching device 4 is installed on the upper part of the mounting frame 3, an induction coil 5 is installed on the front side of the outside of the quenching device, a waterproof shell 6 is fixedly connected inside the cooling tank 1, a cylinder 7 is fixedly connected inside the waterproof shell 6, an output end of the cylinder 7 is fixedly connected with a mounting block 8, auxiliary plates 9 are fixedly connected to both sides of the lower part of the mounting block 8, a first electric push rod 11 is fixedly connected inside the mounting block 8, an output end of the first electric push rod 11 is fixedly connected with a moving block 12, a rack plate 13 is fixedly connected to the outside of the moving block 12, a rotating rod 16 is rotatably connected inside the mounting block 8, a spur gear 15 is fixedly connected to the outside of the rotating rod 16, the rack plate 13 is engaged with the spur gear 15, a slider 14 is fixedly connected to the lower part of the rack plate 13, a fixed block 17 is fixedly connected to the top of the rotating rod 16, a second electric push rod 19 is fixedly connected inside the fixed block 17, an output end of the second electric push rod 19 is fixedly connected with a convex block 20, guide grooves 18 are formed inside the fixed block 17, the convex block 20 is slidably connected inside the guide grooves 18, clamping blocks 21 are slidably connected to the periphery inside the fixed block 17, guide blocks 22 are fixedly connected to both sides of the outside of the plurality of clamping blocks 21, the convex block 20 is in contact with the plurality of clamping blocks 21, a support plate 25 is fixedly connected to the rear side of the outside of the cooling tank 1, a filter box 26 is arranged on the upper part of the support plate 25, a filter assembly 27 is arranged on the outside of the filter box 26, and the filter assembly 27 is used for filtering the smoke generated when the workpiece is cooled. The materials of the plurality of clamping blocks 21 are graphite materials. A chute 24 is formed inside the mounting block 8, and the slider 14 is slidably connected inside the chute 24. Grooves 10 are formed on both sides inside the cooling tank 1, and the two auxiliary plates 9 are slidably connected inside the two grooves 10. Limiting grooves 23 are formed on the periphery inside the fixed block 17, and the plurality of guide blocks 22 are slidably connected inside the plurality of limiting grooves 23. A liquid discharge port 2 is installed on the front side of the outside of the cooling tank 1, and a valve is installed outside the liquid discharge port 2.

[0029] When quenching the reducer gear, first, place the reducer gear outside the four clamping blocks 21. Then, start the second electric push rod 19. The second electric push rod 19 drives the bump 20 fixed to its output end to move upward inside the guide groove 18. When the bump 20 moves, it squeezes the clamping blocks 21 arranged around the outside, causing the four clamping blocks 21 to move outward. By the outward movement of the four clamping blocks 21, the reducer gear to be quenched can be firmly fixed in place. This step ensures that the gear remains stable throughout the quenching process and does not loosen or shift. Next, start the quencher 4. The quencher 4 generates a magnetic field through high-frequency current, and the induction coil 5 heats the surface of the reducer gear. This induction heating method can quickly and efficiently bring the gear surface to the required quenching temperature. At the same time, start the first electric push rod 11. The first electric push rod 11 drives the moving block 12 fixed to its output end to move, and the movement of the moving block 12 drives the rack plate 13 fixed outside to move. When the rack plate 13 moves, it drives the spur gear 15 meshing with it to rotate. The rotation of the spur gear 15 drives the rotating rod 16 fixed inside to rotate inside the mounting block 8. When the rotating rod 16 rotates, it drives the fixed block 17 fixed to the top to rotate together. When the fixed block 17 rotates, it also drives the reducer gear fixed above to rotate, realizing that when quenching the reducer gear, it is convenient to fix the reducer gear and also convenient to rotate the reducer gear. In this way, it can be ensured that the gear surface is evenly heated during the heating process, avoiding problems of local overheating or insufficient heating. Uniform heating helps to form a uniform hardness and structure, thereby improving the overall performance of the gear. Through the quenching method, the wear resistance and fatigue strength of the reducer gear are significantly improved, extending the service life of the gear. At the same time, the uniform hardness distribution and excellent structural performance ensure the stability and reliability of the gear under various working conditions. By setting the drain port 2, it is convenient to replace the coolant inside the cooling tank. The material of the multiple clamping blocks 21 is graphite. Graphite material has good thermal shock resistance when the temperature changes rapidly and is not prone to thermal cracking or breakage, which is particularly important for the working conditions of frequent heating and cooling during the quenching process.

[0030] Refer to Figures 2-7 , the filter assembly 27 includes a mounting shell 2701. The mounting shell 2701 is fixedly connected to the outside of the filter box 26. A blower 2702 is fixedly connected inside the mounting shell 2701. A filter plate 2703 is inserted into the right side inside the filter box 26. An activated carbon plate 2704 is inserted into the left side inside the filter box 26. A delivery pipe 2705 is fixedly connected inside the filter box 26. A smoke collecting hood 2706 is arranged on the upper right side of the cooling box 1. The other end of the delivery pipe 2705 is fixedly connected inside the smoke collecting hood 2706. A mounting rod 28 is fixedly connected to the right side outside the cooling box 1. The top of the mounting rod 28 is fixedly connected to the outside of the smoke collecting hood 2706.

[0031] After the quenching of the reducer gear is completed, the cylinder 7 contracts, driving the mounting block 8 fixed at the top to move downward. While the mounting block 8 moves, it drives the fixed block 17 arranged on the upper part to move together, so that the reducer gear fixed on the fixed block 17 is moved out of the inside of the induction coil 5 and immersed in the inside of the cooling tank 1 for cooling operation. During the cooling process, by starting the fan 2702, the fan 2702 will generate suction, and the smoke generated during cooling is sucked in through the smoke hood 2706. Then, the sucked smoke is transported to the inside of the filter box 26 through the delivery pipe 2705. The smoke entering the inside of the filter box 26 is first preliminarily filtered for the particulate matter in the smoke through the filter plate 2703. The multi-layer structure of the filter plate 2703 can efficiently capture and remove the solid particulate matter in the smoke, preventing these particulate matters from entering the subsequent filtration stage. Next, the smoke that has been preliminarily filtered enters the activated carbon plate 2704 in the filter box 26. The activated carbon plate 2704 has high adsorption capacity and can adsorb the harmful substances in the smoke, including organic compounds, odors and other harmful gases. Through the adsorption of the activated carbon plate 2704, most of the harmful substances in the smoke are effectively removed, further purifying the air. Finally, the gas that has undergone multiple filtration and purification processes is discharged through the mounting shell 2701. It is realized that when the reducer gear is cooled, it is convenient to filter and purify the generated smoke. Through effective filtration and purification, not only the air quality of the working environment is greatly improved, the risk of the operator inhaling harmful smoke is reduced, but also the requirements of environmental protection regulations are met, avoiding environmental pollution. By setting the mounting rod 28, it is convenient to fix and install the smoke hood 2706.

[0032] Working principle: When quenching the reducer gear, first, place the reducer gear outside the four clamping blocks 21. Then, start the second electric push rod 19. The second electric push rod 19 drives the bump 20 fixed to the output end to move upward inside the guide groove 18. When the bump 20 moves, it squeezes the clamping blocks 21 arranged around the outside, causing the four clamping blocks 21 to move outwards. By moving the four clamping blocks 21 outwards, the reducer gear to be quenched can be fixed. Then, start the quencher 4. Through the magnetic field generated by the high-frequency current of the quencher 4, the induction coil 5 will heat the surface of the reducer gear. At the same time, start the first electric push rod 11. The first electric push rod 11 drives the moving block 12 fixed to the output end to move. The moving block 12 moves and drives the rack plate 13 fixed to the outside to move. The rack plate 13 moves and drives the spur gear 15 meshed with the outside to rotate. The spur gear 15 rotates and drives the rotating rod 16 fixed inside to rotate inside the mounting block 8. When the rotating rod 16 rotates, it drives the fixing block 17 fixed to the top to rotate. The fixing block 17 rotates and drives the reducer gear fixed to the upper part to rotate, thus achieving that when quenching the reducer gear, it is convenient to fix the reducer gear and at the same time convenient to rotate the reducer gear, which can ensure uniform heating of the gear surface and avoid problems of local overheating or insufficient heating. Uniform heating helps to form uniform hardness and structure, improving the overall performance of the gear. Then, after the quenching of the reducer gear is completed, the cylinder 7 contracts and drives the mounting block 8 fixed to the top to move. The mounting block 8 moves and drives the fixing block 17 arranged in the upper part to move. The fixing block 17 moves and drives the reducer gear fixed to the upper part to move, so that the quenched reducer gear is removed from the inside of the induction coil 5 and immersed in the cooling tank 1 at the same time for the cooling operation. During cooling, by starting the blower 2702, the smoke generated during cooling is sucked in through the smoke hood 2706. Then, the sucked smoke is conveyed into the filter box 26 through the conveying pipe 2705. For the smoke entering the filter box 26, first, the particulate matter in the smoke is filtered by the filter plate 2703. Then, the harmful substances in the smoke are adsorbed by the activated carbon plate 2704. Finally, the purified gas is discharged through the mounting shell 2701, achieving that when cooling the reducer gear, it is convenient to filter and purify the generated smoke. Through effective filtering and purification, the air quality of the working environment can be greatly improved.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
