[0044] The cooling mechanism includes a moving track 23, which is installed on the top of the workbench 1 through a bracket, and one end of one side of the moving track 23 is fixedly connected to a group of fixtures 22 through a mounting block. A moving device is provided on the same side where the moving track 23 is connected to the mounting block, and the output end of the moving device is connected to a moving member 20, and one end of the moving member 20 is connected to another group of fixtures 22. A through hole is provided through one group of fixtures 22, and the inside of the through hole is rotatably connected to a rotating shaft 19, and a groove for installing a turntable 21 is provided on the side of the other group of fixtures 22 close to the rotating shaft 19, and the turntable 21 is rotatably connected in the groove, and the side of the rotating shaft 19 away from the turntable 21 is connected to a first bevel gear 18, and the other side of the first bevel gear 18 is connected to the output shaft of the second motor 16. A second nozzle 6 for spraying coolant is provided above the workbench 1, and the input end of the second nozzle 6 is connected to a second pipe 5, and the input end of the second pipe 5 is connected to a group of output ends of the coolant tank 11. The present invention is provided with a cooling mechanism, which can drive the turbine moving blades clamped by the clamp 22 to rotate under the action of the motor 16, and at the same time control the second nozzle 6 to spray coolant to cool the turbine moving blades. While the turbine moving blades rotate, the air flow rate is also accelerated, which improves the cooling efficiency of the turbine moving blades. There is no need to move the turbine moving blades to other positions for cooling, thereby solving the problem that the workpiece needs to be moved to the specified position multiple times, which reduces the processing efficiency of the turbine moving blades. The moving device, the collecting device 4, the processing device 13 and the third conveying device are all existing technologies. The third conveying device, such as a water pump, will not be introduced in detail here.

[0045] In certain embodiments, such as Figure 2 As shown, the transmission mechanism includes pillars 15, and the top of the inner wall of the box body 10 is connected to two groups of pillars 15. Figure 4 As shown, the top of one group of pillars 15 is rotatably connected to the second bevel gear 24, and the top of another group of pillars 15 is rotatably connected to the rotating member 31, the second bevel gear 24 is meshedly connected to the first bevel gear 18, the top of the second bevel gear 24 is connected to the first sprocket 25, the top of the rotating member 31 is connected to the second sprocket 27, and the first sprocket 25 and the second sprocket 27 are connected by a chain 26. The present invention drives the first bevel gear 18 to rotate by controlling the motor 16, drives the meshed second bevel gear 24 to rotate, and drives the rotating member 31 to rotate through the chain 26.

[0046] In certain embodiments, such as Figure 5 As shown, the disconnected portion of the first pipe 3 is connected to the first shell 29, the top and bottom of the first shell 29 are penetrated with channels, and one side of the first shell 29 is provided with a slot 32. By arranging the first shell 29 at the disconnected portion of the first pipe 3, the present invention can control the first pipe 3 to be unblocked or blocked.

[0047] In certain embodiments, such as Figure 4 and Figure 5 As shown, the blocking mechanism includes a moving block 28, one side of the moving block 28 is connected to a clamping member 35, the clamping member 35 can be inserted into or detached from the clamping slot 32, and chamfers are symmetrically provided on both sides of the moving block 28. The two sides of the moving block 28 are symmetrically connected to the sliding members 17, and one side of the two groups of sliding members 17 are both slidably connected to the track plate 30. The present invention sets the moving block 28, when the rotating member 31 rotates, the sliding member 17 moves in the direction away from the rotating member 31 along the movement direction of the track plate 30, thereby driving the clamping member 35 to be inserted into the clamping slot 32, blocking the first pipe 3, and the installation direction of the track plate 30 is not horizontal with the groove of the rotating member 31, so that the moving block 28 will not be horizontally inserted into the groove of the rotating member 31, but has a certain inclination angle, which is more conducive to the movement of the moving block 28 with the chamfer.

[0048] In certain embodiments, such as Figure 5 As shown, two sets of second shells 34 are arranged inside the box 10, and the inner wall of the second shell 34 is connected to one end of the spring 33, and the other end of the spring 33 is connected to the sliding member 17. The present invention drives the moving block 28 to slowly insert into the groove of the rotating member 31 when the rotating member 31 stops rotating by arranging the spring 33.

[0049] In certain embodiments, such as Figure 4 As shown, one side of the moving block 28 can be inserted into the groove of the rotating member 31 when the spring 33 is not stretched. The present invention drives the clamping member 35 away from the clamping groove 32 by inserting the moving block 28 into the installation groove.

[0050] In certain embodiments, such as Figure 1 As shown, the fourth pipe 12 is connected to the upper part of the disconnected part of the first pipe 3, and an inclined baffle is provided at the input end of the fourth pipe 12 to prevent the coolant from falling from the upper part of the first pipe 3 and entering the fourth pipe 12. The top of the baffle is connected to the top of the connection part where the fourth pipe 12 is connected to the first pipe 3, and the bottom of the baffle is provided with a certain distance from the connection part. The output end of the fourth pipe 12 is connected to a group of input ends of the coolant tank 11, and the coolant in the fourth pipe 12 is transported to the coolant tank 11 through the second conveying device. The present invention prevents the coolant mixed with debris from entering the fourth pipe 12 when the first pipe 3 is unobstructed by providing an inclined baffle. When the first pipe 3 is blocked, the coolant not mixed with debris will flow into the fourth pipe 12 from the bottom of the inclined baffle when a certain amount is above the first shell 29. The second conveying device, such as a water pump, is a prior art and will not be described in detail here.

[0051] In certain embodiments, such as Figure 2As shown, the output end of the processing device 13 is connected to the input end of the fifth pipe 14, and the output end of the fifth pipe 14 is connected to another set of input ends of the coolant tank 11. The coolant in the processing device 13 is transported to the coolant tank 11 through the fifth pipe 14 via the first transport device. The present invention processes the coolant mixed with debris by setting the processing device 13, and then reuses it. The first transport device, such as a water pump, is a prior art and will not be described in detail here.

[0052] In certain embodiments, such as Figure 1 As shown, the bottom of the workbench 1 is connected to multiple groups of supporting legs 2 for support.

[0053] Working principle: When the present invention is in use, the distance between the two sets of clamps 22 is controlled by the moving device, the turbine moving blades are clamped by the two sets of clamps 22, and then the electric spark punching device 7 is controlled to punch holes. While punching holes, the first nozzle 8 sprays coolant to cool the turbine moving blades. The coolant mixed with debris after spraying is recovered through the collecting device 4 and transported to the processing device 13 through the first pipeline 3 for processing. The turbine moving blades that need to be cooled can control the motor 16 to drive the rotating shaft 19 to rotate. Under the action of the turntable 21, the turbine moving blades can rotate, and the second nozzle 6 is controlled to spray coolant. While the turbine moving blades rotate, the air flow rate is also accelerated. With the help of the coolant, the cooling efficiency of the turbine moving blades is accelerated. The coolant not mixed with debris is recovered through the collecting device 4. When the motor 16 rotates, it drives the first bevel gear 18 to rotate, drives the meshing second bevel gear 24 to rotate, and drives the rotating member 31 to rotate through the chain 26, thereby pushing the moving block 28 to move in the direction of the sliding track, inserting the clamping member 35 into the clamping groove 32 provided in the first shell 29, and blocking the first pipeline 3. When the coolant without debris is above the first shell 29 for a certain amount, it will flow into the fourth pipeline 12 from the bottom of the inclined baffle, and be transported to the coolant tank 11 through the second conveying device. It does not need to be processed by the processing device 13, and the coolant is reused. By setting the spring 33, when the rotating member 31 stops rotating, the moving block 28 is driven to slowly insert into the groove of the rotating member 31, so that the clamping member 35 is away from the clamping groove 32, so that the first pipeline 3 is unobstructed.
