Description

Technical Field

[0001] This utility model relates to the field of flywheel machining technology, and in particular to a flywheel machining heat treatment device. Background Technology

[0002] Heat treatment refers to a metal hot working process in which the chemical composition and structure of a metal material are changed on its surface or inside by means of heating, holding and cooling in the solid state, so as to obtain the desired properties. Quenching is generally used to obtain a high-hardness martensitic structure, and it can also be used to satisfy the special physical and chemical properties such as ferromagnetism and corrosion resistance of certain special steels.

[0003] The existing Chinese patent, CN218026224U, discloses a heat treatment equipment for flywheel processing. This equipment uses a threaded connection between the movable sleeve and the fixed rod to allow the movable sleeve to be removed from the fixed rod, thus enabling the installation and removal of the flywheel body in a convenient and simple manner without overlapping with the surface of the flywheel body.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following problems exist: When using the above-mentioned equipment, due to the fixed inner diameter of the movable sleeve, it cannot be applied to flywheels of different specifications, which reduces the practicality of the equipment. Utility Model Content

[0005] In order to improve the problem that heat treatment equipment cannot clamp flywheels of different specifications and improve its practicality, this application provides a flywheel processing heat treatment device.

[0006] The flywheel processing heat treatment apparatus provided in this application adopts the following technical solution:

A connecting seat is connected to the side wall of the heating chamber, and a heating coil for heat treatment of the workpiece is connected to the connecting seat. A cooling water tank for cooling the workpiece is provided at the bottom of the heating chamber. A lifting hydraulic cylinder is connected to the heating chamber, and a fixed frame is connected to the end of the piston rod of the lifting hydraulic cylinder that passes through the heating chamber. A mounting frame is rotatably connected to the fixed frame, and a rotating component for driving the mounting frame to rotate is provided on the fixed frame. Two clamping rods are provided on the mounting frame, and the clamping rods are located above the heating coil. A driving component for driving the two clamping rods to move relative to each other is provided on the mounting frame. An exhaust vent is provided on the heating chamber, and an exhaust fan is connected to the exhaust vent.

[0008] Preferably, both the fixed frame and the mounting frame are U-shaped. A fixed block is fixedly connected to the mounting frame.

The fixed shaft is fixedly connected to the fixed block and is located on opposite sides of the fixed block. The fixed shaft passes through the first bearing. The rotating motor is connected to the fixed frame, and the output shaft of the rotating motor is coaxially connected to one of the fixed shafts via a coupling.

[0009] Preferably, the drive assembly includes a second bearing, a bidirectional threaded rod, a nut seat, and a drive motor. The second bearing is connected to the mounting bracket, and there is one second bearing at each of the opposite ends of the mounting bracket. The bidirectional threaded rod is connected between the two second bearings. The drive motor is connected to the mounting bracket, and the output shaft of the drive motor is coaxially connected to the bidirectional threaded rod via a coupling. The nut seat is connected to the bidirectional threaded rod, and there are two nut seats on the bidirectional threaded rod.

During operation, the rotating assembly rotates the two clamping rods out of the heating chamber, making it easier for the operator to mount the flywheel onto the two clamping rods. Then, the drive assembly drives the two clamping rods to move away from each other to clamp the flywheel. The rotating assembly then rotates the workpiece into the heating chamber. Next, the lifting hydraulic cylinder lowers the workpiece into the heating coil for heat treatment. After treatment, the lifting hydraulic cylinder lowers the workpiece into the cooling water tank for cooling.

[0021] This application discloses a heat treatment apparatus for flywheel machining. (Refer to...) Figure 1 , Figure 2 and Figure 3 The flywheel processing heat treatment device includes a heating chamber 1, a chamber door 11 connected to the heating chamber 1, a connecting seat 12 connected to the side wall of the heating chamber 1, a heating coil 121 for heat treatment of the workpiece connected to the connecting seat 12, a cooling water tank 2 for cooling the workpiece provided at the bottom of the heating chamber 1, a lifting hydraulic cylinder 3 connected to the heating chamber 1, a fixed frame 31 connected to the end of the piston rod of the lifting hydraulic cylinder 3 that passes through the heating chamber 1, a mounting frame 4 rotatably connected to the fixed frame 31, a rotating component 5 for driving the mounting frame 4 to rotate on the fixed frame 31, a clamping rod 6 provided on the mounting frame 4, two clamping rods 6 provided, the clamping rods 6 are located above the heating coil 121, a driving component 7 for driving the two clamping rods 6 to move relative to each other on the mounting frame 4, an exhaust port provided on the heating chamber 1, and an exhaust fan 13 connected to the exhaust port.

[0022] Both the fixed frame 31 and the mounting frame 4 are arranged in a "U" shape. The mounting frame 4 is fixedly connected to a fixed block 41. The rotating component 5 includes a first bearing 51, a fixed shaft 52 and a rotating motor 53. The first bearing 51 is connected to the fixed frame 31 and is provided on opposite sides of the fixed frame 31. The fixed shaft 52 is fixedly connected to the fixed block 41 and is provided on opposite sides of the fixed block 41. The fixed shaft 52 passes through the first bearing 51. The rotating motor 53 is connected to the fixed frame 31 and the output shaft of the rotating motor 53 is coaxially connected to one of the fixed shafts 52 through a coupling.

[0023] During operation, the fixed shaft 52 is driven to rotate by the rotating motor 53, and the fixed shaft 52 can drive the fixed block 41, the mounting bracket 4 and the structure on the mounting bracket 4 to rotate.

[0024] The drive assembly 7 includes a second bearing 71, a bidirectional threaded rod 72, a nut seat 73, and a drive motor 74. The second bearing 71 is connected to the mounting frame 4, and there is one second bearing 71 at each opposite end of the mounting frame 4. The bidirectional threaded rod 72 is connected between the two second bearings 71. The drive motor 74 is connected to the mounting frame 4, and the output shaft of the drive motor 74 is coaxially connected to the bidirectional threaded rod 72 through a coupling. The nut seat 73 is connected to the bidirectional threaded rod 72, and there are two nut seats 73 on the bidirectional threaded rod 72. The nut seats 73 are cubic in shape, and the sidewalls of the nut seats 73 slide against the sidewalls of the mounting frame 4. One end of the clamping rod 6 is fixedly connected to the nut seat 73.

[0025] When clamping a workpiece, after the workpiece is sleeved on the outside of the two clamping rods 6, the bidirectional threaded rod 72 is driven to rotate by the drive motor 74. Since the nut seat 73 is slidably attached to the mounting bracket 4, the two nut seats 73 can move relative to each other along the length direction of the bidirectional threaded rod 72. After the two clamping rods 6 move away from each other, they can open up and fix the workpiece.

[0026] The clamping rod 6 is a round rod with a right-angle bend at the bottom. The right-angle bends of the two clamping rods 6 are set opposite to each other. With this configuration, when the clamping rod 6 opens and fixes the workpiece, the right-angle bend of the clamping rod 6 can be used to support the workpiece and prevent it from falling.

[0027] The clamping rod 6 is made of heat-resistant and wear-resistant steel, which helps to ensure the service life of the clamping rod 6.

[0028] A dustproof net 14 is connected to the side wall of the heating box 1. The dustproof net 14 is located inside the exhaust port. By setting the dustproof net 14, the entry of external dust into the heating box 1 can be reduced.

[0029] The implementation principle of the flywheel processing heat treatment device in this application embodiment is as follows: During operation, the fixed shaft 52 is driven to rotate by the rotating motor 53. The fixed shaft 52 can drive the fixed block 41, the mounting bracket 4, and the structure on the mounting bracket 4 to rotate, so that the clamping rod 6 rotates out of the heating box 1. This makes it easy for the operator to put the flywheel on the two clamping rods 6, and then put the workpiece on the outside of the two clamping rods 6. The double-threaded rod 72 is driven to rotate by the drive motor 74. The two nut seats 73 can move relative to each other along the length direction of the double-threaded rod 72. After the two clamping rods 6 move away from each other, they can open and fix the workpiece. Then the rotating assembly 5 rotates the workpiece into the heating box 1. Then the lifting hydraulic cylinder 3 lowers the workpiece into the heating coil 121 for heat treatment. After treatment, the lifting hydraulic cylinder 3 lowers the workpiece into the cooling water tank 2 for cooling. At the same time, the exhaust fan 13 is used to discharge the water vapor generated during the cooling process from the heating box 1, thereby improving the problem that the heat treatment equipment cannot clamp flywheels of different specifications and improving its practicality.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
