[0028] This invention provides a heat treatment device for a motor shaft: comprising a base 1, a bracket 2, a rotating shaft 3, a first motor 4, four electric telescopic rods 5, four clamping mechanisms 6, a quenching mechanism 7, and a feeding mechanism 8; the clamping mechanism 6 includes a U-shaped block 61, two clamping blocks 62, a first bidirectional lead screw 63, and a second motor 64; the clamping block 62 is provided with a V-shaped groove 621; the quenching mechanism 7 includes a first vertical plate 71, a first vertical guide rail 72, two first sliders 73, two support plates 74, two first conical top rods 75, a second bidirectional lead screw 76, a third motor 77, a fourth motor 78, and a quenched part 79; the quenched part 79 includes a second vertical guide rail 71, a second vertical guide rail 72, a second vertical guide rail ... a second vertical guide rail 74, a second vertical guide rail 75, a second vertical guide rail 76, a third vertical guide rail 77, a fourth vertical guide rail 78, and a quenched part 79; the quenched part 79 includes a second vertical guide rail 71, a second vertical guide rail 72, a second vertical guide rail 72, a second vertical guide rail 72, a second vertical guide rail 72, a second vertical guide rail 72, a second vertical guide rail 72, a second vertical guide rail 72, a second vertical guide rail 72, a second vertical guide rail 72, a second vertical guide rail 72, a second vertical 91. The second slider 792, the drive screw 793, the fifth motor 794, the induction coil 795, and the water spray ring 796; the quenching mechanism 7 also includes a guide rod 710 and a guide block 711; the unloading mechanism 8 includes a second vertical plate 81, a first hydraulic cylinder 82, a second hydraulic cylinder 83, a worm gear reducer motor 84, and an unloading component 85; the unloading component 85 includes a third vertical guide rail 851, two third sliders 852, two second conical top rods 853, a third bidirectional screw 854, and a sixth motor 855; the base 1 is provided with a water receiving trough 11; the base 1 is provided with a unloading trough 12; the aforementioned solution solves the problem of low processing efficiency.
[0029] Furthermore, the bracket 2 is fixedly mounted on the top of the base 1; the top end of the rotating shaft 3 is rotatably connected to the bracket 2, and the bottom end of the rotating shaft 3 is rotatably connected to the base 1; the first motor 4 is fixedly mounted on the top of the bracket 2, and the output end of the first motor 4 is fixedly connected to the rotating shaft 3; four electric telescopic rods 5 are respectively fixedly mounted on the rotating shaft 3; each electric telescopic rod 5 has a clamping mechanism 6 fixedly mounted on its output end; the quenching mechanism 7 is mounted on the top of the base 1; and the unloading mechanism 8 is mounted on the top of the base 1.
[0030] In this embodiment, the first motor 4 can drive the rotating shaft 3 to rotate, thereby driving the four clamping mechanisms 6 to rotate cyclically; the station closest to the quenching mechanism 7 is the quenching station; the station directly opposite the quenching station is the loading station; the station closest to the unloading mechanism 8 is the unloading station; the station directly opposite the unloading station is the processing station; the quenching mechanism 7 is used to quench the motor shaft; the unloading mechanism 8 is used to remove the quenched motor shaft; multiple motor shafts cyclically pass through each station in sequence, and each station does not affect the others. While waiting for one motor shaft to be quenched, the loading of the next motor shaft to be quenched can be completed, and the unloading of the previous quenched motor shaft can also be completed; thus solving the problem of low processing efficiency.
[0031] In use, the motor shaft is clamped onto the clamping mechanism 6 at the loading station. As the rotating shaft 3 rotates, the motor shaft is first driven to the processing station, and then to the quenching station, where the quenching mechanism 7 quenches the motor shaft. During quenching, the electric telescopic rod 5 shortens, causing the clamping mechanism 6 to release and move away from the quenching motor shaft. After quenching, the electric telescopic rod 5 extends, causing the clamping mechanism 6 to clamp the quenched motor shaft again. Then, the quenched motor shaft is driven to the unloading station, where the clamping mechanism 6 releases, and the unloading mechanism 8 removes the quenched motor shaft.
[0032] Furthermore, the clamping mechanism 6 includes a U-shaped block 61, two clamping blocks 62, a first bidirectional lead screw 63, and a second motor 64; The U-shaped block 61 is fixedly disposed at the output end of the electric telescopic rod 5; the two clamping blocks 62 are slidably disposed within the U-shaped block 61; the clamping block 62 is provided with a V-groove 621; the first bidirectional lead screw 63 is rotatably disposed on the U-shaped block 61 and is threadedly connected to the two clamping blocks 62 respectively; the second motor 64 is fixedly disposed on the U-shaped block 61, and the output end of the second motor 64 is fixedly connected to the first bidirectional lead screw 63.
[0033] In this embodiment, the second motor 64 drives the first bidirectional lead screw 63 to rotate, thereby driving the two clamping blocks 62 to slide in opposite directions. The clamping blocks 62 have V-grooves 621, so when the two clamping blocks 62 come close to each other, they can clamp motor shafts of different sizes.
[0034] Furthermore, the quenching mechanism 7 includes a first vertical plate 71, a first vertical guide rail 72, two first sliders 73, two support plates 74, two first conical top rods 75, a second bidirectional lead screw 76, a third motor 77, a fourth motor 78, and a quenching component 79; The first vertical plate 71 is fixedly mounted on the top of the base 1; the first vertical guide rail 72 is fixedly mounted on the first vertical plate 71; the two first sliders 73 are respectively slidably mounted in the first vertical guide rail 72; the two support plates 74 are respectively fixedly mounted on one side of the first slider 73; the two first conical top rods 75 are respectively rotatably mounted on the two support plates 74. The second bidirectional lead screw 76 is rotatably mounted on the first vertical guide rail 72 and is threadedly connected to the two first sliders 73 respectively; the third motor 77 is fixedly mounted on the top of the first vertical guide rail 72, and the output end of the third motor 77 is fixedly connected to the second bidirectional lead screw 76. The fourth motor 78 is fixedly mounted on the support plate 74 near the third motor 77; the output end of the fourth motor 78 is fixedly connected to the first conical top rod 75 near the fourth motor 78; the quenched part 79 is mounted on the first slider 73 away from the fourth motor 78.
[0035] In this embodiment, the first vertical plate 71 is used to mount the first vertical guide rail 72, and the first vertical guide rail 72 is used to slide the upper and lower first sliders 73. The third motor 77 is used to drive the second bidirectional lead screw 76 to rotate, and the second bidirectional lead screw 76 drives the two first sliders 73 to slide in opposite directions, thereby driving the two support plates 74, and finally driving the two first conical top rods 75 to slide in opposite directions. When the two conical top rods are close to each other, they can hold the two ends of the motor shaft with the axial inner hole to achieve vertical clamping. They can also be adapted to clamp motor shafts of different sizes. After the motor shaft is clamped by the two first conical top rods 75, the clamping mechanism 6 in the quenching station can release the motor shaft and move away from the motor shaft under the drive of the electric telescopic rod 5. The fourth motor 78 drives the first conical top rod 75 to rotate, thereby driving the motor shaft to rotate; then the quenched part 79 completes the quenching treatment of the motor shaft from bottom to top; after the quenching treatment is completed, the electric telescopic rod 5 at the quenching station drives the clamping mechanism 6 to extend and clamp the quenched motor shaft, waiting to be transferred to the unloading station.
[0036] Furthermore, the quenched part 79 includes a second vertical guide rail 791, a second slider 792, a drive screw 793, a fifth motor 794, an induction coil 795, and a water spray ring 796; The second vertical guide rail 791 is fixedly mounted on the first slider 73, which is away from the fourth motor 78; the second slider 792 is slidably mounted inside the second vertical guide rail 791; the drive screw 793 is rotatably mounted on the second vertical guide rail 791 and threadedly connected to the second slider 792; the fifth motor 794 is fixedly mounted on the second vertical guide rail 791; the output end of the fifth motor 794 is fixedly connected to the drive screw 793. The induction coil 795 is fixedly disposed on one side of the second slider 792; the water spray ring 796 is fixedly disposed on one side of the second slider 792.
[0037] In this embodiment, when not in use, the induction coil 795 and the water spray ring 796 are fitted around the first conical top rod 75 at the bottom, and the second vertical guide rail 791 moves with the first slider 73 at the bottom; therefore, the induction coil 795 and the water spray ring 796 also remain relatively stationary with respect to the first conical top rod 75 at the bottom; the induction coil 795 is connected to an external power source, and the water spray ring 796 is connected to an external water source; After the two first conical push rods 75 come together to vertically clamp the motor shaft, the fifth motor 794 starts and drives the drive screw 793 to rotate. The drive screw 793 drives the second slider 792 to rise, which in turn drives the induction coil 795 and the water spray ring 796 to rise. The induction coil 795 heats the motor shaft from bottom to top, and the water spray ring 796 follows closely behind, continuously spraying water onto the motor shaft. After the quenching process is completed, the second slider 792 moves down to the bottom and resets. The induction coil 795 and the water spray ring 796 also reset and are repositioned around the first conical push rod 75 at the bottom.
[0038] Furthermore, the quenching mechanism 7 also includes a guide rod 710 and a guide block 711; The guide rod 710 is fixedly disposed on one side of the first vertical guide rail 72; the guide block 711 is fixedly disposed on one side of the second vertical guide rail 791 and is slidably connected to the guide rod 710.
[0039] In this embodiment, the guide block 711 slides on the guide rod 710, thereby ensuring the stability of the second vertical guide rail 791 as it slides up and down.
[0040] Furthermore, the unloading mechanism 8 includes a second vertical plate 81, a first hydraulic cylinder 82, a second hydraulic cylinder 83, a worm gear reducer motor 84, and an unloading component 85; The second vertical plate 81 is fixedly mounted on the top of the base 1; the cylinder body of the first hydraulic cylinder 82 is rotatably mounted on one side of the second vertical plate 81; the cylinder body of the second hydraulic cylinder 83 is rotatably mounted on one side of the second vertical plate 81 and located above the first hydraulic cylinder 82; the output end of the second hydraulic cylinder 83 is rotatably connected to the cylinder body of the first hydraulic cylinder 82; the worm gear reducer motor 84 is fixedly mounted on the output end of the first hydraulic cylinder 82; the unloading component 85 is fixedly mounted on the output end of the worm gear reducer motor 84.
[0041] In this embodiment, the second hydraulic cylinder 83 is used to control the pitch rotation of the first hydraulic cylinder 82, the first hydraulic cylinder 82 is used to control the movement of the unloading part 85, and the worm gear reducer motor 84 is used to rotate the unloading part 85. After the quenched motor shaft is sent to the unloading station, the unloading component 85 clamps the motor shaft. Then, the clamping mechanism 6 at the unloading station releases the motor shaft. The first hydraulic cylinder 82 drives the motor shaft away from the clamping mechanism 6 at the unloading station. Then, the worm gear reducer motor 84 drives the unloading component 85 to rotate 90 degrees, making the motor shaft horizontal. The second hydraulic cylinder 83 extends, driving the first hydraulic cylinder 82 to rotate downwards, ultimately causing the motor shaft to move down. Finally, the unloading component 85 releases the motor shaft, and the motor shaft falls from a lower height onto the base 1, completing the unloading process.
[0042] Furthermore, the unloading component 85 includes a third vertical guide rail 851, two third sliders 852, two second conical push rods 853, a third bidirectional lead screw 854, and a sixth motor 855; The third vertical guide rail 851 is fixedly installed at the output end of the worm gear reducer motor 84; the two third sliders 852 are respectively slidably installed inside the third vertical guide rail 851; the two second conical push rods 853 are respectively fixedly installed on the two third sliders 852; The third bidirectional lead screw 854 is rotatably mounted on the third vertical guide rail 851 and is threadedly connected to the two third sliders 852 respectively; the sixth motor 855 is fixedly mounted on the third vertical guide rail 851, and the output end of the sixth motor 855 is fixedly connected to the third bidirectional lead screw 854.
[0043] In this embodiment, the sixth motor 855 drives the third bidirectional lead screw 854 to rotate, thereby driving the two third sliders 852 to slide in opposite directions, and finally driving the two second conical top rods 853 to move in opposite directions. When the two second conical top rods 853 come together, the motor shaft can be vertically clamped from both ends of the motor shaft.
[0044] Furthermore, the base 1 is provided with a water receiving trough 11; The water receiving tank 11 is used to catch the water dripping down during the quenching of the motor shaft.
[0045] In this embodiment, the water receiving tank 11 is used to catch the water that drips down after quenching from the water spray ring 796.
[0046] Furthermore, the base 1 is provided with a feeding trough 12; The feeding trough 12 is used to catch the motor shaft after quenching.
[0047] In this embodiment, the feeding trough 12 is an inclined chute that receives the motor shaft and then slides out from one end of the base 1.
[0048] This embodiment describes a heat treatment device for motor shafts. The first motor 4 drives the rotating shaft 3 to rotate, thereby causing the four clamping mechanisms 6 to rotate cyclically. The station closest to the quenching mechanism 7 is the quenching station; the station directly opposite the quenching station is the loading station; the station closest to the unloading mechanism 8 is the unloading station; and the station directly opposite the unloading station is the processing station. The quenching mechanism 7 is used to quench the motor shaft; the unloading mechanism 8 is used to remove the quenched motor shaft. Multiple motor shafts cyclically pass through each station sequentially, with each station independent of the others. While waiting for one motor shaft to be quenched, the loading of the next motor shaft to be quenched can be completed, and the unloading of the previously quenched motor shaft can also be completed, thus solving the problem of low processing efficiency.
