Description

Technical Field

[0001] This utility model relates to the technical field of thin-walled gears, and in particular to a quenching composite heat treatment device for thin-walled gears. Background Technology

[0002] Thin-walled gears are widely used in mechanical transmission, and their performance directly affects the operating efficiency and reliability of mechanical equipment. Quenching and composite heat treatment is a key process for improving the comprehensive mechanical properties of thin-walled gears, such as hardness, wear resistance, and fatigue resistance. However, existing quenching and composite heat treatment processes for thin-walled gears present several problems. Firstly, transferring thin-walled gears from the heating furnace to the quenching cylinder is cumbersome, usually requiring manual handling with tools. This is not only inefficient but also prone to damage due to improper handling, such as gears falling or colliding. Furthermore, manual operation makes it difficult to ensure the timeliness and accuracy of gear transfer, affecting the heat treatment effect. Secondly, if thin-walled gears are not heated and cooled evenly during heating and quenching, they are prone to deformation, leading to a decrease in dimensional accuracy and shape stability, failing to meet the assembly requirements of high-precision mechanical equipment.

[0003] Therefore, we designed a multi-roller sliding contact power supply device to meet the needs of practical applications. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a thin-walled gear quenching composite heat treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A thin-walled gear quenching composite heat treatment device is designed, including a base, a moving mechanism on the base, a rotating mechanism on the moving mechanism, a bracket on the moving mechanism, a first through hole at the top of the bracket, a rotating rod rotatably connected to the inner wall of the first through hole, a thread on the rotating rod, and a slider threadedly connected to the rotating rod.

[0007] The rotating mechanism includes an electric telescopic rod, which is fixedly installed on the top of the slider. The telescopic end of the electric telescopic rod passes through the slider and is fixedly installed on a mounting block. A second through hole is provided on the mounting block, and a shaft is rotatably connected to the inner wall of the second through hole. The bottom end of the shaft passes through the mounting block and is fixedly installed on a hook.

[0008] In detail, the base is a square plate, and a heating furnace and a quenching cylinder are installed on the base.

[0009] In detail, the bracket is an arched frame, and the first through hole is a square groove.

[0010] In detail, a first motor is fixedly installed on the side of the bracket, and the shaft end of the first motor passes through the first through hole and is fixedly connected to one end of the rotating rod.

[0011] In detail, a slide rod is fixedly installed on the inner wall of the first through hole. The slide rod is cylindrical and is horizontally positioned.

[0012] In detail, the slider is a square block and slides on the slider rod.

[0013] In detail, the electric telescopic rod is set vertically, the mounting block is square in shape, a second motor is fixedly installed on the inner wall of the second through hole, and the shaft end of the second motor is fixedly connected to the top end of the shaft.

[0014] Core function: When the thin-walled gear needs to be quenched, the thin-walled gear is suspended on the hook, and then the first motor is started. The first motor drives the rotating rod to rotate. The rotating rod is threaded, which drives the slider to move linearly along the surface of the rod. When the slider moves, it drives the thin-walled gear on the hook to move linearly through the electric telescopic rod, the mounting block and the shaft until the thin-walled gear moves directly above the heating furnace. Then the electric telescopic rod moves the thin-walled gear down until it is lowered into the heating furnace. Then the second motor is started. The second motor drives the thin-walled gear on the hook to rotate through the shaft, thus facilitating the heating of the thin-walled gear.

[0015] After heating, the thin-walled gear is moved out of the heating furnace by an electric telescopic rod. Then, the first motor moves the thin-walled gear to the top of the quenching cylinder. The electric telescopic rod then moves the thin-walled gear down until it enters the quenching cylinder for quenching. This setup avoids the danger of manual operation.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. The moving mechanism facilitates the movement of thin-walled gears from the heating furnace to the quenching cylinder, thus facilitating the processing of thin-walled gears;

[0018] 2. The rotating mechanism facilitates the rotation of the thin-walled gear, which is beneficial for heating and quenching the thin-walled gear. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A thin-walled gear quenching composite heat treatment device includes a base 1, on which a moving mechanism is provided. The moving mechanism facilitates the movement of the thin-walled gear from the heating furnace 4 to the quenching cylinder 5, thus facilitating the processing of the thin-walled gear. The moving mechanism is equipped with a rotating mechanism, which facilitates the rotation of the thin-walled gear, thus facilitating the heating and quenching of the thin-walled gear. The moving mechanism includes a bracket 21, which is fixedly installed on the base 1. The bracket 21 is used to support the opening of a first through hole 25. The top of the bracket 21 has a first through hole 25. The inner wall of the first through hole 25 is rotatably connected to a rotating rod 23. The rotating rod 23 is threaded. The threaded rotating rod 23 facilitates the linear movement of a slider 24 along the surface of a sliding rod 26. The rotating rod 23 is threadedly connected to the slider 24.

[0026] The rotating mechanism includes an electric telescopic rod 31, which is fixedly installed on the top of the slider 24. The electric telescopic rod 31 is used to support the installation of the mounting block 36. The telescopic rod end of the electric telescopic rod 31 passes through the slider 24 and is fixedly installed on the mounting block 36. The mounting block 36 is used to support the opening of the second through hole 34. The mounting block 36 has a second through hole 34. The inner wall of the second through hole 34 is rotatably connected to a shaft 33. The shaft 33 is used to support the installation of the hook 32. The bottom end of the shaft 33 passes through the mounting block 36 and is fixedly installed on the hook 32. The hook 32 is used to suspend the thin-walled gear.

[0027] It should be further noted that the base 1 is a square plate, and a heating furnace 4 and a quenching cylinder 5 are installed on the base 1. The heating furnace 4 is used to heat the thin-walled gear, and the quenching cylinder 5 is used to quench the heated thin-walled gear.

[0028] It should be further noted that the bracket 21 is an arched frame, and the first through hole 25 is a square groove. The bracket 21 is designed to support the installation of the first through hole 25.

[0029] It should be further noted that a first motor 22 is fixedly installed on the side of the bracket 21. The shaft end of the first motor 22 passes through the first through hole 25 and is fixedly connected to one end of the rotating rod 23. The first motor 22 is used to drive the rotating rod 23 to rotate.

[0030] It should be further explained that a slide rod 26 is fixedly installed on the inner wall of the first through hole 25. The slide rod 26 is cylindrical in shape and is set horizontally. The slide rod 26 is set to limit the movement of the slider 24.

[0031] It should be further noted that the slider 24 is a square block and slides on the slide rod 26. The slider 24 is designed to support the installation of the electric telescopic rod 31.

[0032] It should be further explained that the electric telescopic rod 31 is set vertically, the mounting block 36 is a square block, and the second motor 35 is fixedly installed on the inner wall of the second through hole 34. The rotating shaft end of the second motor 35 is fixedly connected to the top end of the shaft 33. The second motor 35 is set to drive the shaft 33 to rotate.

[0033] Working method: When the thin-walled gear needs to be quenched, the thin-walled gear is suspended on the hook 32, and then the first motor 22 is started. The first motor 22 drives the rotating rod 23 to rotate. The rotating rod 23 is threaded, which drives the slider 24 to move linearly along the surface of the sliding rod 26. When the slider 24 moves, it drives the thin-walled gear on the hook 32 to move linearly through the electric telescopic rod 31, the mounting block 36 and the shaft 33 until the thin-walled gear moves directly above the heating furnace 4. Then the electric telescopic rod 31 moves the thin-walled gear down until it moves into the heating furnace 4. Then the second motor 35 is started. The second motor 35 drives the thin-walled gear on the hook 32 to rotate through the shaft 33, thereby facilitating the heating of the thin-walled gear.

[0034] After heating, the thin-walled gear is moved out of the heating furnace 4 by the electric telescopic rod 31, and then moved to the top of the quenching cylinder 5 by the action of the first motor 22. Then, the thin-walled gear is moved down by the electric telescopic rod 31 until it enters the quenching cylinder 5 for quenching. The above settings avoid manual operation and prevent dangerous situations from occurring.
