Description

Technical Field

[0001] This utility model relates to the technical field of heat treatment equipment, specifically a heat treatment device for the inner shell of a new energy vehicle motor. Background Technology

[0002] For the machining of the inner shell of a new energy vehicle motor, the conventional process generally involves rough turning the outer diameter and inner hole first, then finish turning the outer diameter and inner hole, and finally milling. However, due to the characteristics of the inner shell of a new energy vehicle motor, such as thin walls and high material removal rate, the use of conventional processes can easily cause workpiece deformation and concentricity deviation, which cannot meet the precision requirements of the workpiece. At the same time, the workpiece will have unstable quality due to changes in room temperature and cutting fluid temperature during turning, which cannot meet the normal production requirements of the workpiece. Furthermore, the dimensions of the machined workpiece will change after a certain period of time due to the release of its own stress, which will also cause unstable workpiece quality.

[0003] Metal heat treatment is a process in which metal workpieces are heated to a suitable temperature in a certain medium, held at that temperature for a certain time, and then cooled at different rates in different media. By changing the microstructure of the surface or interior of the metal material, its properties can be controlled. However, in actual use, the furnace body itself is large, often occupying a large space in the factory. At the same time, the treatment status of the metal workpiece surface inside the furnace is often not easy for the operator to observe. Moreover, most current heat treatment equipment requires the material to be moved to another place for cooling after heating, which is complicated to operate, inconvenient to use, and difficult to meet the needs of use. Utility Model Content

[0005] This utility model provides the following technical solution: a heat treatment device for the inner shell of a new energy vehicle motor, including a heat treatment furnace. A first heat insulation partition is movably installed inside the heat treatment furnace. Mounting holes are provided below both the heat treatment furnace and mounting holes. A flame-spraying device is movably installed inside the mounting holes. A fuel pipe is fixedly connected to the other end of the flame-spraying device. A mounting frame is fixedly installed on one side of the heat treatment furnace. A first door panel is movably installed in the middle of the mounting frame. A ball screw and a support rod are fixedly installed on the upper end of the first door panel. The upper ends of the ball screw and support rod are movably installed on the mounting frame. A first gear is movably installed in the middle of the ball screw. A second gear is movably installed on one side of the first gear. The bottom end of the second gear is rotatably installed on the mounting frame. A first motor is movably installed on the upper end of the second gear. A cooling box is fixedly installed on the other side of the mounting frame. A second heat insulation partition is movably installed inside the cooling box. Cooling pipes are fixedly connected to both sides of the cooling box. The upper ends of the cooling pipes are fixedly connected to an air handling device and a water tank.

[0006] Preferably, the bottom ends of the heat treatment furnace and the cooling box are both fixedly installed on the base plate, a storage rack is movably installed in the middle of the upper end of the base plate, baffles are fixedly installed at both ends of the storage rack, and rollers are fixedly installed on both sides of the bottom of the storage rack. The rollers are movably installed on the guide rails, and the guide rails are fixedly installed on both sides of the base plate.

[0007] Preferably, a sleeve is fixedly installed at the bottom center of the storage rack, and a screw is movably installed inside the sleeve. One end of the screw is rotatably installed on the inner wall of the heat treatment furnace, and the other end of the screw is fixedly connected to a handwheel.

[0008] Preferably, the sidewalls and top surfaces of the first and second thermal insulation partitions are provided with circular slots, and the circular slots are densely distributed on the sidewalls and top surfaces of the first and second thermal insulation partitions.

[0009] Preferably, the baffle is a thermal insulation board, and the two sides and the top surface of the baffle are in direct contact with the two sides and the top surface of the first thermal insulation board, but are not fixed.

[0010] Preferably, a second door panel is movably installed at the front end of the cooling box, and the structure of the second door panel is completely identical to that of the first door panel. The second door panel is rotated by a second motor.

[0011] Preferably, a pad is movably mounted above the base plate, and the pad wraps around both sides of the rail and the screw.

[0012] A heat treatment device for the inner shell of a new energy vehicle motor includes the following steps:

[0013] Step 1: Place the device on the ground and connect the power supply, fuel source and air pipe. Then place the workpieces to be processed in the upper middle part of the storage rack. Install the storage rack in the upper middle part of the base plate through screws, rollers and rails. Move the storage rack horizontally above the base plate by rotating the handwheel and screw to complete the feeding of the storage rack and workpieces.

[0014] Step 2: The storage rack is first moved into the heat treatment furnace through the cooling box by the rotation of the handwheel and screw. It is then placed inside the heat treatment furnace and the first door panel is moved up and down inside the mounting frame by the rotation of the first motor and the second gear, which in turn drives the rotation of the first gear to completely close the heat treatment furnace. Then, the fuel pipe sends gaseous fuel into the heat treatment furnace through the flame spraying device. The fuel is sprayed and burned at the port of the flame spraying device, which raises the temperature inside the heat treatment furnace and completes the heat treatment process on the surface of the workpiece above the storage rack.

[0015] Step 3: After heating for a certain time, the second door panel is lowered by the second motor to separate the other end of the cooling box. Then the first door panel is lifted, and the handwheel is turned to move the storage rack into the cooling box. When the storage rack is completely inside the cooling box, the first door panel is lowered to disconnect the connection between the heat treatment furnace and the cooling box. The workpiece inside the cooling box is cooled through the cooling pipes and water tank, and the gas inside the cooling box is treated and discharged by the air treatment device.

[0016] Step 4: Repeat steps 2 and 3 above as needed to complete the heat treatment of the motor inner shell. Finally, use a storage rack to move the cooled motor inner shell out of the cooling box and remove the motor inner shell.

[0017] This utility model has the following beneficial effects:

[0018] 1. The heat treatment equipment for the inner shell of the new energy vehicle motor has a cooling box on one side of the heat treatment furnace. The heat treatment furnace and the cooling box are connected by a mounting frame and a first door panel. A storage net frame is movably installed below the heat treatment furnace and the cooling box. This facilitates the smooth transfer of the inner shell of the motor from the heat treatment furnace into the cooling box for timely cooling. This reduces the difficulty of manually transferring the inner shell and the waste of time caused by the heavy load. It also facilitates repeated heating and cooling of the inner shell of the motor.

[0019] 2. The heat treatment equipment for the inner shell of the new energy vehicle motor reduces the heat loss from the heat treatment furnace by installing a cooling box at the outlet of the heat treatment furnace, thus reducing the excessively high temperature at the part removal port. Furthermore, the processed inner shell of the motor can be cooled to room temperature inside the cooling box before being removed, reducing the danger caused by the high temperature on the surface of the inner shell of the motor.

[0020] 3. The heat treatment equipment for the inner shell of the new energy vehicle motor has baffles on both sides of the storage mesh frame. The baffles form a complete box with the front and rear ends of the storage mesh frame and the left and right sides of the first insulation partition, which prevents gas from escaping when the storage mesh frame is heated or cooled, and ensures the safe operation of the device.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5A heat treatment device for the inner shell of a new energy vehicle motor includes a heat treatment furnace 1. A first insulation partition 2 is movably installed inside the heat treatment furnace 1. Mounting holes 3 are provided below both the heat treatment furnace 1 and mounting holes 3. A flame-spraying device 5 is movably installed inside the mounting holes 3. A fuel pipe 6 is fixedly connected to the other end of the flame-spraying device 5. A mounting frame 7 is fixedly installed on one side of the heat treatment furnace 1. A first door plate 8 is movably installed in the middle of the mounting frame 7. A ball screw 9 and a support rod 10 are fixedly installed on the upper end of the first door plate 8. The upper ends of the ball screw 9 and the support rod 10 are movably mounted on the mounting frame 7. A first gear 11 is movably installed in the middle of the ball screw 9. A second gear 12 is movably installed on one side of the first gear 11. The bottom end of the second gear 12 is rotatably mounted on... On the mounting bracket 7, the upper end of the second gear 12 is movably mounted with the first motor 13. A cooling box 14 is fixedly mounted on the other side of the mounting bracket 7. A second door plate 19 is movably mounted on the front end of the cooling box 14, and the structure of the second door plate 19 is completely identical to that of the first door plate 8. The second door plate 19 is rotated by the second motor 20. By installing the cooling box 14 at the outlet of the heat treatment furnace 1, the heat dissipation inside the heat treatment furnace 1 is reduced, which would cause the part removal port temperature to be too high. The processed motor inner shell can be cooled to room temperature inside the cooling box 14 before being removed, reducing the danger caused by the high temperature on the surface of the motor inner shell. A second heat insulation partition 15 is movably mounted inside the cooling box 14. The side walls and top surfaces of the first heat insulation partition 2 and the second heat insulation partition 15 are all opened. The furnace has circular slots 4, which are densely distributed on the side walls and top surface of the first insulation partition 2 and the second insulation partition 15. The first insulation partition 2 and the second insulation partition 15 fix the inner walls of the heat treatment furnace 1 and the cooling box 14, and increase the heat insulation function inside the heat treatment furnace 1 and the cooling box 14. The circular slots 4 connect the side walls of the heat treatment furnace 1 and the cooling box 14, which facilitates the filtration and separation of the flue gas generated during the processing. Cooling pipes 16 are fixedly connected to both sides of the cooling box 14. The upper ends of the cooling pipes 16 are fixedly connected to the air handling unit 17 and the water tank 18. The bottom ends of the heat treatment furnace 1 and the cooling box 14 are fixedly installed on the base plate 25. A storage rack 21 is movably installed in the middle of the upper end of the base plate 25. Both ends are fixedly equipped with baffles 22. Rollers 23 are fixedly installed on both sides of the bottom of the storage rack 21. The rollers 23 are movably mounted on the rails 24. The rails 24 are fixedly mounted on both sides of the base plate 25. A cooling box 14 is provided on one side of the heat treatment furnace 1. The heat treatment furnace 1 and the cooling box 14 are connected by a mounting bracket 7 and a first door plate 8. The storage rack 21 is movably installed below the heat treatment furnace 1 and the cooling box 14. This facilitates the smooth transfer of the motor inner shell inside the heat treatment furnace 1 into the cooling box 14 for timely cooling, reducing the difficulty of manually transferring the motor inner shell and the waste of time. It also facilitates repeated heating and cooling of the motor inner shell. A sleeve 26 is fixedly installed in the middle of the bottom of the storage rack 21.A screw 27 is movably installed inside the sleeve 26. One end of the screw 27 is rotatably mounted on the inner wall of the heat treatment furnace 1, and the other end of the screw 27 is fixedly connected to a handwheel 28. The sleeve 26, screw 27, and handwheel 28 drive the storage rack 21 to move above the base plate 25, facilitating the heating and cooling of the motor inner shell above the storage rack 21. The baffle 22 is a heat insulation plate, and both sides and the top surface of the baffle 22 are in direct contact with the two sides and the top surface of the first heat insulation baffle 2, but are not fixed. The storage rack 21 has baffles 22 on both sides, which form a complete box with the front and rear ends of the storage rack 21 and the left and right sides of the first insulation partition 2. This prevents gas leakage from the storage rack 21 during heating or cooling, ensuring safe operation of the device. A pad is movably installed above the base plate 25, covering both sides of the rail 24 and the screw 27. The pad isolates the heat treatment furnace 1 and the cooling box 14 from the middle of the base plate 25, facilitating heat insulation of the interior of the heat treatment furnace 1 and the cooling box 14.

[0029] A heat treatment device for the inner shell of a new energy vehicle motor includes the following steps:

[0030] Step 1: Place the device on the ground and connect the power supply, fuel source and air pipe. Then place the workpieces to be processed in the upper middle part of the storage rack 21. Install the storage rack 21 in the upper middle part of the base plate 25 through the screw 27, roller 23 and rail 24. Drive the storage rack 21 to move horizontally above the base plate 25 by rotating the handwheel 28 and the screw 27 to complete the feeding of the storage rack 21 and the workpieces.

[0031] Step 2: The storage rack 21 is first moved into the heat treatment furnace 1 through the cooling box 14 by the rotation of the handwheel 28 and screw 27. It is placed inside the heat treatment furnace 1 and the first door plate 8 is moved up and down inside the mounting frame 7 by the rotation of the first motor 13 driving the second gear 12 and the first gear 11, so that the heat treatment furnace 1 is completely closed. Then the fuel pipe 6 sends gaseous fuel into the heat treatment furnace 1 through the flame spraying device 5. The fuel is sprayed and burned at the port of the flame spraying device 5, so that the temperature inside the heat treatment furnace 1 rises and the heat treatment process is completed on the surface of the workpiece above the storage rack 21.

[0032] Step 3: After heating for a certain time, the second door panel 19 is lowered by the second motor 20 to separate the other end of the cooling box 14. Then, the first door panel 8 is lifted, and the handwheel 28 is turned to move the storage rack 21 into the cooling box 14. When the storage rack 21 has completely moved into the cooling box 14, the first door panel 8 is lowered to disconnect the connection between the heat treatment furnace 1 and the cooling box 14. The workpiece inside the cooling box 14 is cooled by the cooling pipe 16 and the water tank 18, and the gas inside the cooling box 14 is treated and discharged by the air treatment device 17.

[0033] Step 4: Repeat steps 2 and 3 above as needed to complete the heat treatment of the motor inner shell. Finally, the cooled motor inner shell is moved out of the cooling box 14 by the storage rack 21 and the motor inner shell is taken out.
