Description

Technical Field

[0001] The utility model relates to the technical field of gear ring processing devices, in particular to a heat treatment device for gear ring processing. Background Art

[0002] The ring gear is inserted into the outer edge of the flywheel after being heated, and fastened to the outer edge of the flywheel after being cooled. It is used to mesh with the starter gear, drive the crankshaft to rotate, and start the engine. During the production and processing of the ring gear, the ring gear needs to be heat treated to ensure its strength and performance.

[0003] At present, in the process of processing the gear ring, when the gear ring needs to be heat treated, the staff opens the door panel by pulling the handle, hangs the gear ring that needs heat treatment on the hanging ring respectively, closes the door panel, and controls the operation of the motor, fan and electric heating tube by controlling the switch group. The fan draws air from the outside of the shell and blows it into the shell. The wind entering the shell is heated by the electric heating tube and then enters the inside of the U-shaped diverter cover. The hot air entering the inside of the U-shaped diverter cover will first be evenly filled in the inside of the U-shaped diverter cover, and the gear ring will not be heated immediately. After the inside of the U-shaped diverter cover is filled with hot air, the hot air will be blown to the gear ring hung on the hanging ring through the through holes evenly opened on the left and right sides and the rear side of the inside of the U-shaped diverter cover. At the same time, the output shaft of the motor drives the first gear to rotate, so that the meshing relationship between the first gear and the outer gear ring causes the first gear to drive the outer gear ring to rotate, and then the outer gear ring drives the rotating shaft to rotate The vertical center of the shell rotates, driving the gear ring hung on the hanging ring to rotate around the vertical center of the shell. In the process of the rotating shaft rotating around the vertical center of the shell, the third gear fixedly sleeved on the upper end of the outer arc surface of the rotating shaft meshes with the second gear to rotate, so that the third gear drives the rotating shaft itself to rotate, and then the rotating shaft drives the gear ring hung on the hanging ring to rotate, so that the gear ring hung on the hanging ring is driven by the rotating shaft to rotate around the vertical center of the shell, and the heated hot air is discharged from the air outlet. Through the coordinated use of the U-shaped diverter cover and the through hole, the hot air can be evenly blown to the gear ring that needs to be heated, and then through the coordinated use of the outer gear ring and the rotating shaft, the gear ring rotates during the revolution around the vertical center of the shell, so that the gear ring can be quickly and evenly heated, the gear ring can be efficiently heated without dead angles, the gear ring can be heated evenly, and the yield of the gear ring is improved.

[0004] For example, a heat treatment device for processing a gear ring disclosed in the authorization number CN219991676U includes a shell, a gear ring rotating mechanism and a heat treatment mechanism; the shell: the left and right sides of the front side are hinged with door panels through hinges, the front sides of the door panels are fixedly connected with handles, the four corners of the lower surface of the shell are threaded with legs, the upper end of the rear inner wall of the shell is provided with an air outlet, and a second filter is arranged in the air outlet; the gear ring rotating mechanism: it is arranged at the inner top of the shell; the heat treatment mechanism: it is arranged between the left and right sides of the shell, and can heat the gear ring efficiently without dead angles, so that the gear ring is heated evenly and the yield of the gear ring is improved. However, such a heat treatment device for processing a gear ring will cause a large amount of heat to be lost after the box door is opened, and because there are a large number of gear rings, it takes time to dismantle, which easily causes the gear rings to be cooled by the external environment for a long time, affecting the later installation and processing, and it is inconvenient to adjust the amount of heat discharged by the exhaust pipe.

[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that a large amount of heat will be lost after the box door is opened. Since there are a large number of gear rings, it takes time to remove them, which can easily cause the gear rings to be cooled by the external environment for a long time and affect the subsequent installation and processing. It is also inconvenient to adjust the amount of heat discharged by the exhaust pipe. Therefore, it is necessary to improve the existing technology. Utility Model Content
