[0034] Please see Figure 1 , Figure 2 and Figure 3 A quenching device for a gear disk includes a platform 1, a water spraying section 2, an inductive heating section 3, a connecting sleeve 4, a first driving section 5, a connecting shaft 6, and a second driving section 7.

[0035] The equipment platform 1 may include a frame 1a, a tabletop 1b, and shielding panels covering the four sides of the frame 1a. The frame 1a may be constructed using aluminum profiles. The tabletop 1b is equipped with a water tank 1c. More specifically, the tabletop 1b may have an outlet for the water tank 1c to enter, and each opening at the top of the water tank 1c may have an outwardly extending flange 1c2, which rests against the tabletop 1b. The flange 1c2 and the tabletop 1b are fixedly connected using bolts or glue.

[0036] The water spray unit 2 is installed on the equipment platform 1 and is used to add water to the water tank 1c. The water tank 1c also has a water outlet 1c1. That is to say, by designing the size of the water outlet 1c1 and the water adding speed of the water spray unit 2, the water in the water tank 1c is kept at a certain volume while flowing.

[0037] Please see Figure 3 and Figure 5 In some embodiments, the water tank 1c is cylindrical, and correspondingly, the flange 1c2 is annular. The water spray unit 2 is also annular and is installed at the top opening of the water tank 1c, that is, installed on the flange 1c2. The water spray unit 2 has a pipe 2a inside, multiple water spray nozzles 2b connected to the pipe 2a on the inner wall, and an inlet 2c connected to the pipe 2a on the outer wall.

[0038] When the gear disk is immersed in water for cooling, it first passes through these spray nozzles 2b.

[0039] Please see Figure 2 and Figure 3 The inductive heating unit 3 is installed on the equipment platform 1, directly above the water tank 1c.

[0040] The connecting sleeve 4 is rotatably connected to the bottom plate of the water tank 1c around a vertical axis. Bearings can be used, and a sealing treatment can be applied.

[0041] The first drive unit 5 is used to drive the connecting sleeve 4 to rotate. More specifically, the frame 1a is fixedly provided with a first mounting plate 1a1 below the tabletop 1b; the first drive unit 5 uses a first motor, which is fixedly connected to the first mounting plate 1a1, and the output shaft of the first motor and the connecting sleeve 4 are driven by a synchronous belt. In addition, the first mounting plate 1a1 can also provide support for the water tank 1c, making the water tank 1c more stable.

[0042] The connecting shaft 6 is slidably connected to the connecting sleeve 4, meaning the axis of the connecting shaft 6 is also vertical, passes through the connecting sleeve 4, and is sealed. The connecting shaft 6 also rotates together with the connecting sleeve 4. More specifically, the connecting shaft 6 is provided with a key, and the connecting sleeve 4 is provided with a groove for the matching key.

[0043] The connecting shaft 6 extends upward through the upper part of the connecting sleeve 4 in a stepped shape, which is used to place the gear disk.

[0044] The second drive unit 7 drives the connecting shaft 6 to slide up and down, allowing the upper protruding part of the connecting shaft 6 to pass through the inductive heating unit 3. The upper protruding part can stop above, within, and below the inductive heating unit 3. While the upper protruding part stops above the inductive heating unit 3, a worker inserts a gear disc into it. While the upper protruding part stops within the inductive heating unit 3, the inductive heating unit 3 heats the teeth of the gear disc. While the upper protruding part stops below the inductive heating unit 3, the heated gear disc is immersed in water to cool.

[0045] A button is designed to initiate the operation of the first drive unit 5 and the second drive unit 7 for one cycle. Initially, the upper protruding part is positioned above the inductive heating unit 3, fitted with a gear disk. Then, pressing the button causes the first drive to rotate the connecting shaft 6, while the second drive causes the connecting shaft 6 to move downwards into the inductive heating unit 3, stop there, move downwards below the inductive heating unit 3, stop there, and move upwards back above the inductive heating unit 3. Finally, the first drive unit 5 and the second drive unit 7 stop, and the connecting shaft 6 returns to its initial state.

[0046] During the time that the upper protruding part stays in the inductive heating section 3 and below the inductive heating section 3, the connecting shaft 6 rotates, driving the gear disk to rotate together, so that the heating and cooling of the gear disk's teeth is more uniform and sufficient.

[0047] In some embodiments, the second drive unit 7 can be a cylinder. A solenoid valve controls the extension, retraction, and stopping of the cylinder's telescopic rod. Three sensors correspond to three positions at different heights, and a PLC controls the solenoid valve's electromagnet.

[0048] In some embodiments, the second drive unit 7 includes a cam 7a and a second motor 7b.

[0049] Cam 7a is rotatably connected to equipment platform 1 about a vertical axis. More specifically, a second mounting plate 1a2 is fixedly mounted on frame 1a below platform 1b, and cam 7a is rotatably connected to the second mounting plate 1a2 via bearings.

[0050] The second motor 7b is used to drive the cam 7a to rotate. More specifically, the second motor 7b is connected to a worm gear reducer 7b1, which is fixedly connected to the second mounting plate 1a2. The output shaft of the reducer 7b1 and the cam 7a are driven by a synchronous belt.

[0051] The top surface of cam 7a is an annular surface 7a1, which is stepped and serves as abutment for the lower end of connecting shaft 6. In other words, the annular surface 7a1, viewed from above, has three planar positions at different heights, connected by inclined planes. During cam 7a's rotation: as the lower end of connecting shaft 6 abuts against the inclined plane, it rises or falls according to the direction of the inclined plane; when the lower end of connecting shaft 6 abuts against the planar surface, it remains stationary. Furthermore, a universal ball can be mounted on the lower end of connecting shaft 6, with point contact between the ball and annular surface 7a1, ensuring smoother movement between the connecting shaft 6 and annular surface 7a1.

[0052] The three planar positions correspond to: the upper part protruding above the inductive heating part 3, in the inductive heating part 3, and below the inductive heating part 3.

[0053] In the top view, the plane and the inclined plane that make up the annular surface 7a1 are both fan-shaped annular. By designing the parameters of the reducer and the second motor 7b, the time it takes for the cam 7a to rotate one revolution can be controlled; by designing the angle corresponding to the plane, the dwell time of the connecting shaft 6 at the corresponding position can be controlled; by designing the angle corresponding to the inclined plane, the time it takes for the connecting shaft 6 to rise / fall can be controlled.

[0054] Compared to using a cylinder, the second drive unit 7 uses a cam 7a. One rotation of the cam 7a is one cycle of operation required for the second drive unit 7, which makes it easier to control and coordinate with the first drive unit 5.

[0055] Please see Figure 4 In some embodiments, based on the above-described embodiment where "the second drive unit 7 includes a cam 7a and a second motor 7b", the annular surface 7a1 sequentially includes a first plane 7a11, a first inclined plane 7a12, a second plane 7a13 lower than the first plane 7a11, a second inclined plane 7a14, a third plane 7a15 lower than the second plane 7a13, a third inclined plane 7a16, a fourth plane 7a17 lower than the third plane 7a15, and a fourth inclined plane 7a18.

[0056] The design incorporates four planes, allowing the upper protruding portion of the connecting shaft 6 to accommodate two gear discs simultaneously, resulting in higher efficiency. The lower end of the connecting shaft 6 abuts against the first plane 7a11, with the upper protruding portion above the inductive heating unit 3; the lower end of the connecting shaft 6 abuts against the second plane 7a13, with the lower gear disc within the inductive heating unit 3; the lower end of the connecting shaft 6 abuts against the third plane 7a15, with the upper gear disc within the inductive heating unit 3; and the lower end of the connecting shaft 6 abuts against the fourth plane 7a17, with both gear discs located below the inductive heating unit 3 and immersed in water.

[0057] Please see Figure 6In some embodiments, the quenching apparatus for the gear disk also includes a fume extractor 8. The fume extractor 8 generates an airflow that enters from the air inlet via a fan. For ease of illustration, only the air inlet is shown in the figures to represent the fume extractor 8. The air inlet is located directly above the inductive heating unit 3.

[0058] When the heated gear disc comes into contact with water, it will produce steam. The smoke extractor 8 is used to remove this steam, making it easier to observe the condition of the gear disc.
