[0025] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0026] like Figure 1-3As shown, this utility model provides an armature shaft quenching device, including a quenching pool 1. A lifting bracket 2 is fixedly connected to the rear top of the quenching pool 1, and a feeding mesh tray 3 is fixedly installed on the front side of the lifting bracket 2. A cooling mechanism 4, which runs through the front and rear, is fixedly connected to the middle of the bottom end of the quenching pool 1. A draining mechanism 5 is fixedly connected to the lower left side of the quenching pool 1. The cooling mechanism 4 includes a heat dissipation square tube 41, which is fixedly connected to the middle of the bottom end of the quenching pool 1. Dustproof nets 42 are fixedly connected to both the front and rear ends of the inner surface of the heat dissipation square tube 41. Several flow grooves 43 are opened at the top of the heat dissipation square tube 41. The front and rear ends of the flow grooves 43 respectively extend to the front and rear sides of the lower inner wall of the quenching pool 1. Filter screens 44 are fixedly connected to both the front and rear ends of the inner wall of the flow grooves 43. Several heat dissipation fins 45 are fixedly connected to the inner surface of the heat dissipation square tube 41, and several heat dissipation fins 45 are fixedly connected to the top of the heat dissipation fins 45. A metal heat-absorbing plate 46 extends through the top of the flow channel 43. Movable slots are provided on both the front and rear sides of the upper part of the heat-dissipating square tube 41. A first motor 47 is fixedly connected to the inner wall of the movable slot. A pulley 48 is fixedly connected to the output shaft of the first motor 47. A transmission belt 49 is connected to the outer surface of the pulley 48. Support frames 411 are fixed on both the front and rear sides of the inner surface of the heat-dissipating square tube 41. A pulley 410 is movably connected to the side of the support frame 411 near the dustproof net 42. The outer surface of the pulley 410 is connected to the lower part of the inner surface of the transmission belt 49. A heat-dissipating fan 412 is fixedly connected to the side of the pulley 410 near the support frame 411. The heat-dissipating fan 412 is movably connected to the side of the support frame 411 away from the pulley 410. The end of the pulley 48 away from the first motor 47 extends through the interior of the flow channel 43 and is fixedly connected to a guide fan 413.

[0027] When the quenching device is in use, starting the first motor 47 causes the pulley 48 to drive the guide fan 413 to rotate inside the flow channel 43, allowing the medium in the quenching pool 1 to circulate within the flow channel 43. The heat in the quenching medium is absorbed by the metal heat-absorbing plate 46 and dissipated to the heat exhaust square tube 41 by the heat dissipation fins 45. While the pulley 48 is rotating, the transmission belt 49 drives the pulley 410 to rotate, causing the heat exhaust fan 412 to rotate and exhaust the heat from the heat exhaust square tube 41, thus completing the cooling and heat dissipation of the quenching medium. This prevents the high temperature of the medium from affecting the quenching effect and makes the quenching device more convenient to use.

[0028] like Figure 4-5As shown, this utility model provides an armature shaft quenching device. The draining mechanism 5 includes a draining tank 51, which is fixedly connected to the lower left side of the quenching tank 1. A draining pipe 52, extending through the left and right sides, is fixedly connected to the upper part of the draining tank 51. A filter plate 53 is fixedly connected to the left side of the inner wall of the draining pipe 52. A chip removal groove 54 is provided at the bottom of the inner wall of the draining pipe 52. The bottom end of the chip removal groove 54 extends to the bottom of the draining tank 51 and is provided with a collection box 55. The collection box 55 is slidably inserted into the upper right side of the inner wall of the chip removal groove 54, which is rotatably connected to a closing baffle 56. The left end of the closing baffle 56 extends to the bottom right side of the filter plate 53. A sliding groove is provided in the middle of the right surface of the chip removal groove 54. The top of the inner wall of the sliding groove is fixedly connected to... There is a second motor 57, and the output shaft of the second motor 57 is fixedly connected to a transmission screw 58. The outer surface of the transmission screw 58 is threadedly connected to a threaded slider 59. The outer surface of the threaded slider 59 is slidably connected to the inner surface of the sliding groove. The left side of the threaded slider 59 is movably connected to a push rod 510. The top of the push rod 510 is movably connected to the bottom left side of the closed baffle 56. The top of the closed baffle 56 is movably connected to a pull rod 511. The top of the pull rod 511 is slidably connected to a sliding scraper 512. The sliding scraper 512 is slidably connected to the right side of the filter plate 53. The front and rear sides of the interior of the sliding scraper 512 are slidably connected to a vertically penetrating limiting slide post 513. The top of the limiting slide post 513 is fixedly connected to the upper surface of the inner wall of the drain pipe 52.

[0029] When the quenching medium is discharged through the drain pipe 52, the filter plate 53 filters the impurities in the medium, ensuring that the recovered medium can be used normally. Then, by starting the second motor 57, the transmission screw 58 can be driven to rotate, and the threaded slider 59 can slide inside the sliding groove. Thus, the push rod 510 can pull the closed baffle 56, so that the impurities filtered by the filter plate 53 can fall from the chip trough 54 into the recovery box 55. The pull rod 511 can pull the sliding scraper 512 to slide along the limiting slide post 513, thereby scraping off the impurities on the filter plate 53, which facilitates the treatment of impurities in the quenching medium and makes the quenching of the armature shaft more convenient.

[0030] The working principle of this armature shaft quenching device will be explained in detail below.

[0031] like Figure 1-5As shown, during the quenching process of automobile and motorcycle armature shafts, the armature shaft is first placed on the feeding tray 3. Then, driven by the lifting bracket 2, the feeding tray 3, along with the armature shaft, is immersed in the quenching tank 1 for quenching. After quenching, the first motor 47 starts, driving pulley 48 to rotate, which in turn causes the guide fan 413 to push the quenching medium to circulate in the flow channel 43. The metal heat-absorbing plate 46 absorbs the heat in the quenching medium, while the heat dissipation fins 45 dissipate this heat to the heat dissipation square tube 41. At the same time, the rotation of pulley 48 is transmitted through the transmission belt 4. 9 is transferred to pulley 410, which causes the heat dissipation fan 412 to discharge the heat from the heat dissipation square tube 41, thereby achieving cooling and heat dissipation of the quenching medium. After the quenching medium is processed, it is discharged through drain pipe 52 and impurities in the medium are removed through filter plate 53. Then, the start of the second motor 57 causes the transmission screw 58 to drive the threaded slider 59 to move, which in turn pulls the closed baffle 56 through push rod 510, so that the impurities fall into chip trough 54 and are finally collected in recycling box 55. This simplifies the handling of impurities during the armature shaft quenching process and makes the whole quenching process more convenient and efficient.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
