DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments:

[0023] As Figure 1-2As shown in the figure, the utility model provides a quenching device for machine tool parts, which includes a base 1. A stirring device body 4 is arranged inside the base 1. A liquid extraction pump 2 is fixedly connected to the right side of the base 1. The output end of the liquid extraction pump 2 is fixedly connected to a water outlet pipe 3. The input end of the liquid extraction pump 2 is fixedly connected to a liquid extraction pipe 8. The right side of the base 1 is fixedly connected to the water outlet pipe 3. A cooling box 7 is fixedly connected to the rear side of the base 1. A fixing frame 5 is fixedly connected to the upper side of the base 1. A transmission mechanism 6 is arranged below the fixing frame 5. The transmission mechanism 6 includes a motor 61. The output end of the motor 61 is fixedly connected to a threaded rod 62. The upper end of the outer wall of the threaded rod 62 is fixedly connected to a driving wheel 63. The outer wall of the driving wheel 63 is drivingly connected to a transmission belt 64. The inner surface of the transmission belt 64 is movably connected to a driven wheel 65. The lower side of the driven wheel 65 is fixedly connected to the threaded rod 62. A fixing plate 9 is threadedly connected to the outer wall of the threaded rod 62. Fixed blocks 10 are fixedly connected to the opposite surfaces of the two fixing plates 9. First, place the processed part 25 on the fixed blocks 10. After limiting and fixing, turn on the motor 61. The motor 61 can drive the threaded rod 62 to rotate. The rotation of the threaded rod 62 can drive the driving wheel 63 to rotate. The driving wheel 63 can drive the driven wheel 65 to rotate through the transmission belt 64. Therefore, the threaded rods 62 on both sides can be driven to rotate simultaneously. When the threaded rods 62 on both sides rotate, they can drive the fixing plate 9 to rise or fall, thereby driving the fixed blocks 10 to rise or fall. Therefore, the processed part 25 can be automatically quenched.

[0024] As Figure 3-4As shown in the figure, the utility model provides a technical solution: Preferably, two guide posts 12 are fixedly connected to the left side of the inner wall of the fixed block 10. A first spring 11 is sleeved on the outer wall of the guide post 12. One end of the first spring 11 is fixedly connected to the fixed block 10, and the other end of the first spring 11 is fixedly connected to a moving plate 13. The outer wall of the guide post 12 is slidably connected to the moving plate 13. A moving block 14 is fixedly connected to the upper side of the moving plate 13. A processing part 25 is movably connected to the upper side of the fixed block 10. Activity grooves are formed at both the left and right ends of the upper side of the fixed block 10. The outer wall of the moving block 14 is slidably connected to the activity grooves. A connecting frame 15 is fixedly connected to the side of the moving block 14 away from the processing part 25. A U-shaped rod 18 is rotatably connected to the inner surface of the moving block 14. A stretching column 16 is fixedly connected to the inner surface of the connecting frame 15. The other end of the stretching column 16 is fixedly connected to a stop block. The U-shaped rod 18 is movably connected to the stop block on the side close to the connecting frame 15. A second spring 17 is sleeved on the outer wall of the stretching column 16. One end of the second spring 17 is fixedly connected to the connecting frame 15, and the other end of the second spring 17 is fixedly connected to the stop block. During the process of clamping and fixing the part, first pull the moving blocks 14 on both sides. The movement of the moving blocks 14 will compress the first spring 11. Then place the processing part 25 on the fixed block 10 and release the moving blocks 14. At this time, the first spring 11 will drive the moving plate 13 to reset. The movement of the moving plate 13 can drive the moving blocks 14 to move. The moving blocks 14 can clamp and limit the processing part 25. When the moving blocks 14 come into contact with the processing part 25, the processing part 25 will squeeze the U-shaped rod 18, thereby driving the U-shaped rod 18 to rotate. The rotation of the U-shaped rod 18 will squeeze the second spring 17. Therefore, the rotation of the U-shaped rod 18 can clamp and fix the upper side of the part, preventing the part from shifting and improving the quenching quality of the device.

[0025] As Figure 5As shown in the figure, the utility model provides a technical solution: Preferably, a connecting pipe 19 is fixedly connected through the front side of the cooling box 7, an upper part of the inner wall of the cooling box 7 is fixedly connected with a partition plate 20, two heat conducting plates 21 are fixedly connected through the upper side of the partition plate 20, a front end of the upper side of the partition plate 20 is fixedly connected with a blower 22, an input end of the blower 22 is fixedly connected with an air extraction pipe 23, an output end of the blower 22 is fixedly connected with a blowing pipe 24, one end of the liquid extraction pipe 8 far from the liquid extraction pump 2 is fixedly connected through the cooling box 7, and a plurality of ventilation holes are formed through the front side of the heat conducting plate 21. When circulating and cooling the water inside the device, the blower 22 can be turned on. At this time, the quenched water from the outside will enter the inside of the cooling box 7. Then, the heat conducting plate 21 will conduct the heat inside the cooling box 7 to the upper part of the cooling box 7. Then, the blower 22 will blow the outside air to the heat conducting plate 21 through the blowing pipe 24, make full contact with the heat conducting plate 21, and take out the heat conducted by the heat conducting plate 21. The cooled liquid will be re-transported to the inside of the base 1 through the liquid extraction pump 2. When the stirring device body 4 is turned on, the stirring device body 4 can stir the cooled water to ensure that the cooled liquid is in full contact with the parts, shorten the quenching time of the device for the parts, and reduce the quenching cost.

[0026] The working principle of the quenching device for machine tool parts will be specifically described below.

[0027] As Figure 1-5As shown in the figure, first place the machined part 25 on the fixed block 10. During the process of clamping and fixing the part, first pull the moving blocks 14 on both sides. When the moving blocks 14 move, they will compress the first spring 11. Then place the machined part 25 on the fixed block 10 and release the moving blocks 14. At this time, the first spring 11 will drive the moving plate 13 to reset. The movement of the moving plate 13 can drive the moving blocks 14 to move, and the moving blocks 14 can clamp and limit the machined part 25. When the moving blocks 14 contact the machined part 25, the machined part 25 will squeeze the U-shaped rod 18, thereby driving the U-shaped rod 18 to rotate. The rotation of the U-shaped rod 18 will squeeze the second spring 17. Therefore, the rotation of the U-shaped rod 18 can clamp and fix the upper side of the part, prevent the part from shifting, improve the quenching quality of the device. After the limit fixing is completed, turn on the motor 61. The motor 61 can drive the threaded rod 62 to rotate. The rotation of the threaded rod 62 can drive the driving wheel 63 to rotate. The driving wheel 63 can drive the driven wheel 65 to rotate through the transmission belt 64. Therefore, the threaded rods 62 on both sides can be driven to rotate simultaneously. When the threaded rods 62 on both sides rotate, they can drive the fixed plate 9 to rise or fall, thereby driving the fixed block 10 to rise or fall. Therefore, the machined part 25 can be automatically quenched. When circulating and cooling the water inside the device, the fan 22 can be turned on. At this time, the quenched water from the outside will enter the inside of the cooling tank 7. Then the heat conducting plate 21 will conduct the heat inside the cooling tank 7 to the upper part of the cooling tank 7. Then the fan 22 will blow the outside air to the heat conducting plate 21 through the air blowing pipe 24 to fully contact the heat conducting plate 21 and take out the heat conducted by the heat conducting plate 21. The cooled liquid will be re-transported to the inside of the base 1 by the liquid pumping pump 2. When the stirring device body 4 is turned on, the stirring device body 4 can stir the cooled water to ensure that the cooled liquid is in full contact with the part, shorten the quenching time of the device for the part, and reduce the quenching cost.

[0028] The above text generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
