[0002] Heat treatment refers to a metal hot working process in which materials are heated, held, and cooled in the solid state to obtain the desired microstructure and properties.

[0024] Embodiment

[0025] Such as Figure 1As shown in the figure, a gear heat treatment clamping tool proposed by the present utility model includes a support column 1 and a support cross plate 3. A fixed plate 5 is fixedly connected to the support cross plate 3. A baffle 6 for isolating high temperature is fixedly installed on the fixed plate 5. The baffle 6 is made of a transparent material. Both the fixed plate 5 and the baffle 6 are set in an arc shape, so as to provide an arc-shaped wrapping range for blocking high temperature. An observation window 601 for observation is opened on the baffle 6. A support plate 7 is fixedly connected above the observation window 601 of the baffle 6. A fan 8 for controlling the air flow direction is installed on the support plate 7. The air flow blown by the fan 8 can change the air flow direction at the position of the observation window 601, so as to introduce air to pass through the observation window 601, achieving the effect of cooling while blocking high temperature.

[0026] As Figure 1 and Figure 3 shown in the figure, a support rod 2 is rotatably connected to the support column 1. The top end of the support rod 2 is connected to the support cross plate 3. The entire device can be rotated through the support rod 2.

[0027] As Figure 1 shown in the figure, a counterweight 4 is fixedly installed on the support cross plate 3. A group of connecting plates 9 are fixedly connected to the support cross plate 3. A grip rod 10 is fixedly connected to the two connecting plates 9. A clamping mechanism 11 for clamping the gear is arranged on the support cross plate 3. The balance of the device is achieved through the counterweight 4. The clamping mechanism 11 is used for clamping and fixing the gear.

[0028] As Figure 1-2 shown in the figure, the clamping mechanism 11 includes a first electric push rod 1101. One end of the first electric push rod 1101 is connected to the support cross plate 3. The other end of the first electric push rod 1101 is fixedly connected to a support frame 1102. A limit cross plate 1103 is fixedly connected to the support frame 1102. A group of limit plates 1104 are slidably connected to the limit cross plate 1103. A second electric push rod 1105 is fixedly connected between the two limit plates 1104. Right-angle plates 1106 are fixedly connected to the two limit plates 1104. Limit blocks 1107 are fixedly connected to the two right-angle plates 1106. By expanding and contracting the first electric push rod 1101, the clamping device can be driven to move up and down. By expanding and contracting the second electric push rod 1105, the limit plates 1104, the right-angle plates 1106 and the limit blocks 1107 are driven to move, so as to clamp and fix the gear.

[0029] As Figure 1 shown in the figure, a quenching tank 12 for quenching the gear is fixedly connected to one side of the support column 1. A valve 1201 is fixedly connected to the quenching tank 12. Liquid is injected into the quenching tank 12 for quickly cooling the high-temperature gear.

[0030] As Figure 1As shown, on the other side of the support column 1, there is a fixedly connected support platform 13. A high-frequency quenching device 14 for heating the gear is fixedly installed on the support platform 13. The model of the high-frequency quenching device 14 is ZHGP-35AB II - high-frequency induction heating. The high-frequency quenching device 14 is used to directly heat the gear.

[0031] In this embodiment, first, the gear is placed into the heating ring on the support platform 13 and above the high-frequency quenching device 14, and then the gear is heated. After the heating is completed, the color of the gear is observed through the observation window 601, and it is judged whether to continue heating according to the time. Then, the first electric push rod 1101 is extended to drive the clamping device to move up and down. By extending the second electric push rod 1105, the limiting plate 1104, the right-angle plate 1106, and the limiting block 1107 are driven to move, so as to clamp and fix the gear. Then, by holding the hand grip 10, under the action of the support rod 2, the support cross plate 3 is driven to move, so as to move the heated gear above the quenching tank 12, and then quenching is carried out. Through rapid cooling, high hardness and wear resistance are obtained on the surface of the gear. The high temperature during this period can be blocked by the baffle 6. After the quenching is completed, by rotating the support cross plate 3, the gear is continuously placed into the heating ring for heating. Tempering is carried out to reduce the brittleness after quenching, improve the toughness and comprehensive mechanical properties. Finally, the gear is taken out after it cools down.

[0032] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
