Technical Field
[0001] This application relates to the field of fixture technology, and in particular to a heat treatment fixture. Background Technology
[0002] Heat treatment fixtures are widely used in heat treatment processes, primarily for quenching, tempering, annealing, and normalizing of various metallic materials. They play a crucial role in heat treatment, effectively preventing workpiece deformation at high temperatures, ensuring consistent heat treatment results, and improving processing efficiency. However, existing heat treatment fixtures sometimes prevent localized heating of the workpiece due to the contact surface between the fixture and the workpiece, leading to uneven heating. Therefore, this paper proposes a new type of heat treatment fixture. Utility Model Content
[0003] In order to solve the problem that the contact surface between the existing heat treatment fixture and the part will prevent the part from being heated locally, resulting in uneven heating of the part, this application provides a heat treatment fixture.

A rotating shaft is fixedly connected to one side of each set of clamping plates. The rotating shaft is rotatably connected to the clamping seat. A gear is fixedly connected to one end of each rotating shaft. A torsion spring is sleeved on the outer surface of the other end of each rotating shaft. One end of the torsion spring is fixedly connected to the end of the rotating shaft, and the other end of the torsion spring is fixedly connected to the clamping seat. A slider is provided on the outer surface of each clamping seat. Toothed plates that mesh with the two sets of gears are fixedly connected to both sides of each slider. A driving mechanism is provided on the handle, which can drive the two sets of sliders to move alternately.
[0006] Preferably, the driving mechanism includes movable slots on both sides of the handle, each movable slot having a movable block installed inside it, and a spring fixedly connected between the inner surface of the movable slot and the movable block. A pull rope is fixedly connected between the movable block and the slider on the same side, with one end of the pull rope passing through the side wall of the handle to the inside of the movable slot. A motor is fixedly installed in the middle of the handle, and a rotating plate is fixedly connected to the output shaft of the motor. A push rod is fixedly connected radially to the outer surface of the rotating plate. Two sets of movable blocks are located on both sides of the rotating plate, and the side of the two sets of movable blocks that are close to each other is provided with an arc-shaped protrusion.
[0007] Preferably, one side of the handle is configured as a U-shaped structure, and the two sets of clamps are located on both sides of the open end of the handle.
[0008] Preferably, the handle has grooves on both sides of its open end, and one end of the slider is fitted inside the groove to form a sliding pair.
[0009] Preferably, the side of the clamps away from the clamping seat is all set to be arc-shaped, and the two sets of clamps on the same clamping seat are symmetrically arranged.
[0010] In summary, this application includes the following beneficial technical effects:
[0011] This invention, by setting up a driving mechanism, allows two sets of sliders to move alternately during heat treatment, thereby enabling the clamps on both sides of the workpiece to open alternately, preventing the contact surface between the clamps and the workpiece from always being the same, thus facilitating the workpiece to be heated.

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0017] This application discloses a heat treatment fixture, including a handle 1. A symmetrically arranged clamping seat 2 is fixedly connected to the outer surface of the handle 1. Two sets of clamping plates 3 are provided on each clamping seat 2. A rotating shaft 7 is fixedly connected to one side of each set of clamping plates 3. The rotating shaft 7 is rotatably connected to the clamping seat 2. A gear 8 is fixedly connected to one end of each rotating shaft 7. A torsion spring 16 is sleeved on the outer surface of the other end of each rotating shaft 7. One end of the torsion spring 16 is fixedly connected to the end of the rotating shaft 7. The other end of the torsion spring 16 is fixedly connected to the clamping seat 2. A slider 10 is provided on the outer surface of each clamping seat 2. A toothed plate 9 that meshes with the two sets of gears 8 is fixedly connected to both sides of each slider 10. A driving mechanism is provided on the handle 1. The driving mechanism can drive the two sets of sliders 10 to move alternately.
[0018] Furthermore, one side of the handle 1 is configured with a U-shaped structure, and two sets of clamps 2 are located on both sides of the open end of the handle 1.
[0019] Furthermore, both sides of the open end of the handle 1 are provided with sliding grooves 11, and one end of the slider 10 is fitted inside the sliding groove 11 to form a sliding pair inside it.
[0020] Furthermore, the side of the clamping plate 3 away from the clamping seat 2 is all set to be arc-shaped, and the two sets of clamping plates 3 located on the same clamping seat 2 are symmetrically arranged.
[0021] In this embodiment, firstly, the user can manually move the two sets of sliders 10, thereby moving all the toothed plates 9 simultaneously, which in turn drives the gear 8, the rotating shaft 7, and the clamping plate 3 to rotate simultaneously. At this time, the torsion spring 16 undergoes elastic deformation, and the clamping plate 3 opens. Then, the workpiece to be processed is placed between the two sets of clamping plates 3, and the two sliders 10 are released. The torsion spring 16 returns to its original position, thereby driving the rotating shaft 7, the gear 8, and the clamping plate 3 to return to their original position, and the clamping plate 3 can then clamp the workpiece. In addition, by setting a drive mechanism, during heat treatment, the drive mechanism drives the two sets of sliders 10 to move alternately, thereby enabling the clamping plates 3 on both sides of the workpiece to open alternately, avoiding the contact surface between the clamping plate 3 and the workpiece being always the same, so as to facilitate the workpiece being heated.
[0022] Furthermore, the drive mechanism includes movable slots 13 on both sides of the handle 1. Movable blocks 15 are installed inside each movable slot 13. A spring 14 is fixedly connected between the inner surface of the movable slot 13 and the movable block 15. A pull rope 12 is fixedly connected between the movable block 15 on the same side and the slider 10. One end of the pull rope 12 passes through the side wall of the handle 1 to the inside of the movable slot 13. A motor 4 is fixedly installed in the middle of the handle 1. A rotating plate 5 is fixedly connected to the output shaft of the motor 4. A push rod 6 is fixedly connected to the outer surface of the rotating plate 5 radially. Two sets of movable blocks 15 are located on both sides of the rotating plate 5. The side of the two sets of movable blocks 15 that are close to each other is set with an arc-shaped protrusion.
[0023] In this embodiment, the motor 4 drives the rotating plate 5 and the push rod 6 to rotate. When the push rod 6 rotates close to the moving block 15, the push rod 6 moves along the arc surface of the moving block 15, pushing the moving block 15 to move along the moving groove 13. At this time, the moving block 15 compresses the spring 14, and the pull rope 12 is pulled by the moving block 15 to drive the slider 10 to move. When the push rod 6 rotates away from the moving block 15, the compressed spring 14 returns to its original position, driving the moving block 15 to return to its original position. Therefore, when the motor 4 drives the rotating plate 5 and the push rod 6 to rotate continuously, the push rod 6 can drive the two sets of sliders 10 to move alternately, so that the clamping plates 3 on both sides of the workpiece open alternately.
