Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] When a heat treatment equipment with high-efficiency heating is used, in order to quench the gear teeth more accurately, a high-frequency heater is usually used for heating. During the heating process, only the gear teeth are heated, completing the heating link in the gear quenching process more accurately and efficiently.

[0023] To this end, an embodiment of the present invention provides a heat treatment device with high-efficiency heating, the purpose of which is at least to heat the relative teeth of the two gears 2 synchronously by arranging two groups of fixed drive components 4 on one side of the quenching box 1 and arranging a high-frequency heater 31 between the two groups of fixed drive components 4.

Each group of the fixed drive components 4 includes a fixed shaft 41, one end of the fixed shaft 41 extends above the quenching pool 102, and the other end of the fixed shaft 41 is rotatably mounted on the side wall of one side of the quenching box 1; The heating assembly 3 is used to heat the teeth of the gear 2 on the fixed driving assembly 4. The heating assembly 3 includes a high-frequency heater 31 arranged between two groups of fixed driving assemblies 4. A telescopic rod 32 for adjusting the position of the high-frequency heater 31 is fixedly installed on the side wall of the quenching box 1.

[0025] In the present invention, two groups of fixed drive components 4 are arranged on one side of the quenching box 1, and the fixed drive components 4 can drive the two gears 2 to rotate relative to each other. By arranging a high-frequency heater 31 between the two groups of fixed drive components 4, the relative teeth of the two gears 2 can be heated synchronously. After the two gears 2 are heated, the telescopic rod 32 drives the high-frequency heater 31 to retract, and then the two groups of fixed drive components 4 drive the two relatively rotating gears 2 to rotate relative to each other, so that the two heated teeth of the gears 2 move downward. When the heated teeth of the two gears 2 are immersed in the quenching liquid (water, oil or polymer) inside the quenching pool 102, the teeth are quickly cooled down, and then the quenching treatment of the teeth of the gear 2 is completed; each extension and retraction of the high-frequency heater 31 can pass through the two teeth of the two gears 2 placed opposite to each other, and the two teeth on the two gears 2 can be heated at the same time, so that the heating power of the high-frequency heater 31 can be fully utilized, and the quenching treatment of the teeth of the gear 2 can be completed more efficiently.

[0026] Furthermore, if Figure 4 As shown, the end of the high-frequency heater 31 extends between the two groups of fixed driving components 4, a base plate 33 is provided at the tail of the high-frequency heater 31, the telescopic end of the telescopic rod 32 is fixedly connected to the side of the base plate 33 away from the high-frequency heater 31, and the telescopic rod 32 is used to drive the high-frequency heater 31 to extend between the two groups of fixed driving components 4.

[0027] Among them, by setting a telescopic rod 32 at the tail of the high-frequency heater 31 and setting the high-frequency heater 31 between two groups of fixed driving components 4, the two oppositely placed gears 2 can be heated more conveniently, and the teeth of the two oppositely placed gears 2 can be heated more efficiently and accurately.

[0028] Furthermore, if Figure 4 As shown, an adsorption plate 42 is fixedly mounted on the fixed shaft 41, and the adsorption plate 42 is used to adsorb and fix the gear 2 to be heated and quenched. A mounting shaft 43 is coaxially fixedly connected to one end of the fixed shaft 41 facing the side wall of the quenching box 1. The mounting shaft 43 rotates through the side wall of the quenching box 1, and a transmission sleeve 44 is sleeved on the mounting shaft 43 for driving the mounting shaft 43 to rotate in one direction. A driving sleeve 35 is sleeved on the outer side of the transmission sleeve 44 for guiding the transmission sleeve 44 to rotate.

[0029] Among them, by setting an adsorption plate 42 on the fixed shaft 41, the gear 2 can be conveniently adsorbed and fixed on the fixed shaft 41 after the gear 2 is sleeved on the fixed shaft 41; by setting a transmission sleeve 44 on the outside of the mounting shaft 43 and setting a drive sleeve 35 on the outside of the transmission sleeve 44, the drive sleeve 35 can be used to drive the transmission sleeve 44 to adjust the rotation angle.

[0030] Furthermore, if Figure 5 and Figure 6 As shown, the transmission sleeve 44 is connected to the installation shaft 43 through a one-way transmission bearing 45, and the one-way transmission bearing 45 is used to drive the two fixed shafts 41 to rotate relative to each other. The outer side of the transmission sleeve 44 is provided with a plurality of guide bevel grooves 4401 distributed in a circumferential manner, and the inner wall of the drive sleeve 35 is provided with sliding balls 351 distributed in a circumferential manner. The sliding balls 351 are slidably installed inside the guide bevel grooves 4401, and the side of the drive sleeve 35 is provided with a T-shaped frame 34 for driving the drive sleeve 35 to move linearly.

[0031] Among them, by setting a guide bevel groove 4401 on the outer side of the transmission sleeve 44 and setting a sliding ball 351 inside the driving sleeve 35, the sliding ball 351 moves linearly under the drive of the driving sleeve 35, and can drive the transmission sleeve 44 to rotate. By driving the driving sleeve 35 to move axially along the fixed shaft 41, the fixed shaft 41 can be driven to rotate, and the rotation angle of the gear 2 located on the fixed shaft 41 can be adjusted.

[0032] Furthermore, if Figure 4 and Figure 5 As shown, a guide rod 36 is fixedly installed parallel to the side wall of the quenching box 1 away from the fixed axis 41, and an elastic member 37 is sleeved on the guide rod 36 for driving the T-shaped frame 34 to move toward the fixed axis 41. A protrusion is provided at the bottom of the base plate 33, and the protrusion is used to abut against the side of the T-shaped frame 34 when the tail of the base plate 33 moves away from the fixed axis 41, and drive the T-shaped frame 34 to move in the direction away from the fixed axis 41.

[0033] Among them, by sleeved on the guide rod 36 an elastic member 37 for driving the T-shaped frame 34 to move toward the fixed axis 41, when the telescopic rod 32 drives the high-frequency heater 31 to retract to a certain position, the bottom of the substrate 33 will be pressed against the side of the T-shaped frame 34 facing the fixed axis 41 and drive the T-shaped frame 34 to move away from the fixed axis 41, so that the elastic member 37 is in a force storage state. When the telescopic rod 32 drives the high-frequency heater 31 to extend in the initial stage, the elastic member 37 drives the T-shaped frame 34 to move toward the fixed axis 41, so that the driving sleeves 35 at both ends of the T-shaped frame 34 drive the fixed axis 41 and the gear 2 located on the fixed axis 41 to deflect at an angle.

[0034] Furthermore, if Figure 7As shown, the reflux component 5 includes a pressing pump 51, and a liquid inlet pipe 52 and a liquid outlet pipe 53 are respectively arranged on the pressing pump 51. The other end of the liquid inlet pipe 52 extends into the heat dissipation pool 101 of the quenching box 1 and is connected with the interior of the heat dissipation pool 101. The other end of the liquid outlet pipe 53 extends into the quenching pool 102 inside the quenching box 1 and is connected with the interior of the quenching pool 102. A pressure plate 55 is installed above the pressing pump 51 for sliding up and down, and the pressure plate 55 is used to squeeze the pressing pump 51.

[0035] Furthermore, if Figure 4 As shown, the lower end of the T-shaped frame 34 extends above the pressure plate 55, and a first wedge block 38 is fixedly installed on the lower end of the T-shaped frame 34. A second wedge block 551 is provided on the upper end surface of the pressure plate 55. When the T-shaped frame 34 moves away from the fixed axis 41 driven by the base plate 33, the first wedge block 38 pushes the second wedge block 551 to move downward, thereby squeezing the pressing pump 51.

[0036] Among them, by arranging a pressing pump 51 under the T-shaped frame 34, during the linear sliding process of the T-shaped frame 34, the first wedge block 38 under the T-shaped frame 34 cooperates with the second wedge block 551 on the pressure plate 55, and the pressing pump 51 can be synchronously driven to guide the quenching medium located inside the heat dissipation pool 101 to the inside of the quenching pool 102, so that the inside of the quenching pool 102 can be continuously maintained at a low temperature state, and the quenching medium can be recycled.

[0037] Furthermore, if Figure 7 As shown, a rectangular plate 54 is provided at one end of the liquid outlet pipe 53 extending into the quenching pool 102 inside the quenching box 1. The rectangular plate 54 is located directly below the gear 2. The interior of the rectangular plate 54 is hollow. The rectangular plate 54 is connected to the interior of the liquid outlet pipe 53. A plurality of nozzles 541 are provided on the upper end surface of the rectangular plate 54. The plurality of nozzles 541 are distributed along the contour of the upper end surface of the rectangular plate 54. The plurality of nozzles 541 are used to spray quenching liquid into the quenching pool 102.

[0038] Among them, by setting a rectangular plate 54 at the bottom of the quenching pool 102 and setting multiple nozzles 541 along the contour of the rectangular plate 54, the quenching medium output by the pressing pump 51 can directly reach the surface of the gear 2, come into contact with the gear 2, and cool the surface of the gear 2, which can improve the cooling effect of the gear surface and provide a quenching effect.

[0039] Furthermore, if Figure 1 and Figure 2 As shown, the upper end surface of the partition 12 is provided with two arc grooves corresponding to the contour of the gear 2, and the inner wall of each of the arc grooves is provided with two figure-eight inclined grooves 1201, and the inclined grooves 1201 are used to guide the quenching liquid from the quenching pool 102 to flow into the heat dissipation pool 101.

[0040] Among them, by setting an arc groove corresponding to the position of the gear 2 on the partition 12, it can be more convenient to remove the gear 2 from the fixed shaft 41. In addition, an eight-shaped inclined groove 1201 is set on the inner wall of the arc groove, so that the quenching medium overflowing from the quenching pool 102 flows downward along the inclined groove 1201, and the quenching medium flows more dispersedly on the step plate 11, so that the quenching medium can fully dissipate heat, which is convenient for the quenching medium to be used again for cooling and quenching.

[0041] Working principle: During the quenching heat treatment of the gear 2, the two gears 2 to be quenched are first respectively mounted on the two fixed shafts 41, and then the position of the gear 2 is fixed by the adsorption plate 42, and then the high-frequency heater 31 is started, and the high-frequency heater 31 is driven by the telescopic rod 32 to extend between the two gears 2 (in the process of extending the telescopic rod 32, the T-shaped frame 34 is released to move toward the fixed shaft 41, so that the sliding balls 351 inside the driving sleeves 35 on both sides of the T-shaped frame 34 slide inside the guide inclined groove 4401 to adjust the rotation angle of the fixed shaft 41), and the two opposite teeth of the two gears 2 are heated, and then the telescopic rod 32 drives the high-frequency heater 31 to retract, and in the process of retracting the telescopic rod 32 The substrate 33 between the high-frequency heater 31 will abut against the T-frame 34, driving the T-frame 34 to move in the direction away from the fixed shaft 41, so that the T-frame 34 drives the driving sleeves 35 on both sides to move away from the fixed shaft 41. At the same time, the lower end of the T-frame 34 will also drive the first wedge block 38 to move synchronously, so that the first wedge block 38 squeezes the second wedge block 551, and drives the pressure plate 55 to squeeze the pressing pump 51, and transports the quenching medium inside the heat dissipation pool 101 to the inside of the quenching pool 102. After that, this action is repeated many times, and multiple teeth on the gear 2 can be heated separately. At the same time, as the gear 2 rotates, the heated teeth of the gear 2 will move and be immersed in the quenching medium inside the quenching pool 102, completing the quenching treatment of the teeth of the gear 2.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
