[0022] Example 1:

[0023] Please see Figures 1-5 In this embodiment of the present invention, the combined fixture for heat treatment of metal parts includes a fixed plate 1, with a heat insulation plate 2 fixedly connected to one end of the fixed plate 1. A fixed block 8 is fixedly connected to the bottom of the heat insulation plate 2, and a fixed clamping block 9 is fixedly connected to the end of the fixed block 8 away from the heat insulation plate 2. A fixed clamping cone 10 is fixedly connected to the top of the fixed clamping block 9. A limiting component 7 is provided on the side wall of the heat insulation plate 2 at the top of the fixed block 8 to limit the movement range of the movable clamping block 5. A plurality of movable blocks 4 are evenly arranged at the end of the heat insulation plate 2 near the limiting component 7. A movable clamping block 5 is fixedly connected to the end of each movable block 4 away from the heat insulation plate 2, and a movable clamping cone 6 is fixedly connected to the end of each movable clamping block 5 near the limiting component 7.

[0024] Furthermore, the dimensions of multiple movable blocks 4 are matched with the dimensions of fixed block 8, the dimensions of multiple movable clamping blocks 5 are matched with the dimensions of fixed clamping block 9, and the dimensions of multiple movable clamping cones 6 are matched with the dimensions of fixed clamping cones 10. This design ensures that the fixture maintains a stable structure and uniform clamping force when clamping parts.

[0025] Example 2:

[0026] Based on Example 1, this example further describes the driving mechanism of the clamp. For example... Figure 1 and 2 As shown, multiple electric actuators 13 are evenly arranged at the end of the fixed plate 1 away from the heat insulation plate 2, and each electric actuator 13 has a telescopic rod 15 fixedly connected to its output end. The telescopic rods 15 are fixedly connected to the side walls of the corresponding connecting blocks 17, and the connecting blocks 17 are fixedly connected to the movable block 4 through the connecting plate 16. A fixing ring 14 is fixedly connected to the outer wall of each electric actuator 13, and the fixing ring 14 is fixedly connected to the side wall of the fixed plate 1. When the electric actuators 13 are working, the telescopic rods 15 push the connecting blocks 17 and the connecting plate 16 to move, thereby driving the movable block 4, the movable clamping block 5, and the movable clamping cone 6 to move, thus achieving the clamping and release of the parts.

[0027] In addition, a connecting rod 11 is provided on the bottom side wall of the end of the fixing plate 1 away from the heat insulation plate 2. The connecting rod 11 is detachably connected to the fixing plate 1 via a fixing lug 12. Multiple switches are evenly arranged on the top of the connecting rod 11 at the end away from the fixing plate 1 to control the start and stop of the electric push rod 13.

[0028] Working principle: The metal part to be heat-treated is placed between the fixed clamping cone 10 and the movable clamping cone 6. Then, the electric push rod 13 is activated, which pushes the connecting block 17 and the connecting plate 16 to move via the telescopic rod 15, thereby moving the movable block 4, the movable clamping block 5, and the movable clamping cone 6 closer to the fixed clamping cone 10. When the movable clamping cone 6 contacts the surface of the part and generates a certain clamping force, the part is firmly clamped in the fixture. During the clamping process, the buffer spring 73 and the telescopic column 74 in the limiting assembly 7 can absorb and disperse the impact of the clamping force on the part, preventing the part from being damaged by excessive clamping force. The clamped part is then placed in a heat treatment furnace for heating, cooling, and other treatments. The heat insulation plate 2 effectively isolates the high temperature from heat conduction to other parts of the fixture, protecting the structural integrity and service life of the fixture. After the heat treatment is completed, the electric push rod 13 is closed, the telescopic rod 15 retracts, the movable clamping cone 6 separates from the part, and the part can be removed from the fixture.
