[0017] 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.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a lever flipping mechanism cooling fixture, including a worktable 1, with multiple sets of support legs 2 welded to the lower end of the worktable 1, and reinforcing rods 3 and longitudinal connecting rods 4 welded between the lower ends of the support legs 2. The bottom of the support legs 2 is equipped with self-locking rollers. The worktable 1 has a feeding groove 6 on its upper surface, in which a workpiece 25 is placed. The feeding groove 6 has reference positioning blocks 7 at its edge, a Z-axis support block 8 in the middle, and a windproof cover 5 surrounding the feeding groove 6. A cooling fan 22 is installed at the lower end of the windproof cover 5, and a fiber optic temperature sensor is located on one side of the feeding groove 6. It should be noted that the fiber optic temperature sensor uses a publicly available model, such as AF28-op. The tic3000 sensor has a temperature range of -30℃ to +125℃, which meets the temperature control requirements of this technical solution. The fiber optic temperature sensor is electrically connected to the cooling fan 22 via the control module. When the temperature is set to be greater than 50℃, the cooling fan 22 is started. When the temperature drops to 40℃ after air cooling, the cooling fan 22 is turned off to stop air cooling. A fan rotation switch 24 is installed at the front end of the cooling fan 22. A manual valve control switch 23 is provided on one side of the upper end of the worktable 1. It should be noted that the fan rotation switch 24 and the manual valve control switch 23 in this technical solution use existing technology to control the opening and closing of the cooling fan 22 and the cylinder 12 respectively via wires. The electrical control principle of this opening and closing is existing technology and will not be described in detail here.

[0019] Furthermore, the manual valve control switch 23 is electrically connected to the cylinder 12 via a wire.

[0020] Furthermore, the fan rotation switch 24 is electrically connected to the cooling fan 22 via wires, and the cooling fan 22 is electrically connected to the fiber optic temperature sensor via wires.

[0021] A first rotating mounting base 10 is installed on the upper end face of the crossbeam reinforcing rod 3. A first joint rotating shaft 11 is inserted through the first rotating mounting base 10. A cylinder 12 is movably mounted on the first joint rotating shaft 11. It should be noted that: the tail of the cylinder 12 is provided with a mounting connector, and the connector plug of the mounting connector is rotatably connected to the first rotating mounting base 10 through the first joint rotating shaft 11. One end of the cylinder 12 is provided with a pneumatic telescopic arm 13, and the other end of the pneumatic telescopic arm 13 is provided with a first connector plug 14. The first connector plug 14 is rotatably connected to the second rotating mounting base 15 through the second joint rotating shaft 20. The upper end of the second rotating mounting base 15 is provided with a longitudinal connecting arm 16. The top end of the longitudinal connecting arm 16 is welded and fixedly connected to the pressure cover 21. The lower end face of the pressure cover 21 is provided with a pressure cover limiting block 9.

[0022] Furthermore, the pressure cap limiting block 9 and the Z-direction support block 8 are staggered.

[0023] In one embodiment, when the pressure cap 21 is pressed down, the workpiece 25 is limited and fixed by the pressure cap limiting block 9 and the Z-direction support block 8 which are distributed in a staggered manner, so as to better perform air cooling heat dissipation on the placed workpiece 25.

[0024] The longitudinal connecting arm 16 is provided with a third rotating mounting seat 17 on one side, and the upper end of the third rotating mounting seat 17 is welded and fixedly connected to the pressure cover 21. The third rotating mounting seat 17 is rotatably connected to the flipping mechanism fulcrum 19 through the third joint rotation shaft 18, and the flipping mechanism fulcrum 19 is welded to the side of the worktable.

[0025] Furthermore, the pressure cap 21, through the first joint rotation shaft 11, the second joint rotation shaft 20 and the third joint rotation shaft 18, in conjunction with the extension and retraction of the cylinder 12 and the pneumatic telescopic arm 13, constitutes a flipping and pressing mechanism.

[0026] In one embodiment, when it is necessary to cool and shape the high-temperature workpiece 5, the pressure cap 21 is first opened. Then, the workpiece 5 is manually positioned and placed in the feeding trough 6 by the reference positioning block 7 and the Z-axis support block 8. Then, the cylinder 12 is started by controlling the manual valve control switch 23. The cylinder 12 drives the pneumatic telescopic arm 13 inside to extend. During the extension, the first connecting plug 14 connected to the pneumatic telescopic arm 13 is pushed to rotate in the second rotary mounting base 15, and pushes the second rotary mounting base 15 and the longitudinal connecting arm 16 connected to it upward. During the upward movement of the longitudinal connecting arm 16, the third rotary mounting base 17 also moves synchronously. The third rotary mounting base 17 is limited to rotation by the flipping mechanism fulcrum 19 through the third joint rotation shaft 18, thereby causing the cylinder 12 to drive the pneumatic telescopic arm 13 to rotate upward. As the retractable arm 13 extends, it drives multiple joint rotation axes and rotating mounting bases to flip and press the pressure cover 21, thereby pressing the workpiece 5 placed on the pressure cover 21. The pressure cover limiting block 9 further limits the position of the workpiece 25. After the workpiece 25 is pressed and fixed, the cooling mechanism is turned on by the fan rotation switch 24. The fiber optic temperature sensor senses the real-time temperature of the workpiece 25. When the detected temperature is greater than 50°C, the controller starts the cooling fan 22 to cool the placed workpiece. When the temperature drops to 40°C after cooling, the cooling fan 22 is turned off to stop the cooling. Then, following the reverse steps of the pressing action, the limiting and pressing of the workpiece 25 is released by the contraction of the cylinder 12, and the workpiece is taken out, completing the cooling of the product and achieving the purpose of preventing product deformation after cooling.
