DETAILED DESCRIPTION

[0034] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0035] The present invention provides a turbine blade positioning and punching device, such as Figure 1 The figure shows a turbine blade positioning and punching device. Figure 1As shown, an electric spark drilling device 7 for drilling holes is disposed above the workbench 1. A first nozzle 8 for spraying coolant is disposed on one side of the electric spark drilling device 7. The input end of the first nozzle 8 is connected to the output end of a third pipe 9, and the input end of the third pipe 9 is connected to another set of output ends of a coolant tank 11. The present invention utilizes the electric spark drilling device 7 to drill holes in turbine blades, and utilizes the first nozzle 8 to spray coolant to reduce temperatures during machining. The electric spark drilling device 7 is conventional technology and will not be described in detail here.

[0036] In certain embodiments, as Figure 1 and Figure 3 As shown, it includes a workbench 1, the top of which is connected to a hollow box 10;

[0037] A cooling mechanism for cooling the turbine blades is provided above the workbench 1;

[0038] A coolant tank 11 for storing coolant is provided above the workbench 1;

[0039] A collecting device 4 for collecting coolant is provided below the workbench 1;

[0040] The box 10 is provided with a treatment device 13 for treating waste coolant;

[0041] The output end of the collecting device 4 is connected to the input end of the first pipe 3, and the output end of the first pipe 3 is connected to the input end of the processing device 13. The coolant in the collecting device 4 is transported from the first pipe 3 to the processing device 13 through the third transport device.

[0042] The first pipe 3 is provided with a disconnection point, and the disconnection point is provided with a blocking mechanism for blocking the first pipe 3;

[0043] The box body 10 is provided with a transmission mechanism for driving the blocking mechanism to move;

[0044] The cooling mechanism includes a movable track 23, which is mounted on the top of the workbench 1 via a bracket. One end of the movable track 23 is fixedly connected to a set of fixtures 22 via a mounting block. A movable device is provided on the same side of the movable track 23 as the mounting block. The output end of the movable device is connected to a movable member 20, and one end of the movable member 20 is connected to another set of fixtures 22. A through hole is provided through one set of fixtures 22, and a rotationally connected shaft 19 is provided inside the through hole. A groove for mounting a turntable 21 is provided on the side of the other set of fixtures 22 near the shaft 19, and the turntable 21 is rotationally connected in the groove. The side of the shaft 19 away from the turntable 21 is connected to the 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 the second pipe 5, and the input end of the second pipe 5 is connected to a set of output ends of the coolant tank 11. The present invention is provided with a cooling mechanism, which can drive the turbine 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 blades. While the turbine blades rotate, the air flow rate is also accelerated, which speeds up the cooling efficiency of the turbine blades. There is no need to move the turbine 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 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, 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, as shown in FIG. Figure 4 As shown, the tops of one group of pillars 15 are rotatably connected to the second bevel gear 24, and the tops of the other group of pillars 15 are rotatably connected to the rotating member 31. The second bevel gear 24 is meshed with the first bevel gear 18. The tops of the second bevel gears 24 are connected to the first sprocket 25. The tops of the rotating member 31 are connected to the second sprocket 27. The first sprocket 25 and the second sprocket 27 are connected by a chain 26. The present invention controls the motor 16 to drive the first bevel gear 18 to rotate, 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, as Figure 5 As shown, the disconnected portion of the first pipe 3 is connected to the first housing 29. Passages are formed through the top and bottom of the first housing 29, and a slot 32 is formed on one side of the first housing 29. By disposing the first housing 29 at the disconnected portion of the first pipe 3, the present invention can control whether the first pipe 3 is unobstructed or blocked.

[0047] In certain embodiments, as Figure 4 and Figure 5 As shown, the blocking mechanism includes a moving block 28, one side of which is connected to a clamping member 35. The clamping member 35 can be inserted into or detached from the clamping slot 32. Chamfers are symmetrically provided on both sides of the moving block 28. The moving block 28 is symmetrically connected to sliding members 17 on both sides. One side of both sets of sliding members 17 is slidably connected to the track plate 30. The present invention provides the moving block 28. When the rotating member 31 rotates, the sliding member 17 moves 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. In addition, 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, combined with the chamfers, is more conducive to the movement of the moving block 28.

[0048] In certain embodiments, as Figure 5 As shown, two sets of second shells 34 are provided inside the housing 10. The inner wall of the second shell 34 is connected to one end of a spring 33, and the other end of the spring 33 is connected to the sliding member 17. By providing the spring 33, 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.

[0049] In certain embodiments, 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 slot 32 by inserting the moving block 28 into the installation slot.

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

[0051] In certain embodiments, 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 from the fifth pipe 14 to the coolant tank 11 via the first delivery device. The present invention uses the processing device 13 to treat the coolant mixed with debris and then reuse it. The first delivery device, such as a water pump, is conventional technology and will not be described in detail here.

[0052] In certain embodiments, 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 controlling the moving device, the turbine 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, the first nozzle 8 sprays coolant to cool the turbine blades. The coolant mixed with debris after spraying is recovered by the collecting device 4 and transported to the processing device 13 through the first pipe 3 for processing. The turbine 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 blades can rotate. At the same time, the second nozzle 6 is controlled to spray coolant. While the turbine blades rotate, the air flow rate is also accelerated. In combination with the coolant, the cooling efficiency of the turbine blades is accelerated. The coolant not mixed with debris is recovered by 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 card 35 into the card slot 32 opened in the first shell 29, and blocking the first pipe 3. When the coolant without debris is above a certain amount above the first shell 29, it will flow into the fourth pipe 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, it drives the moving block 28 to slowly insert into the groove of the rotating member 31, so that the card 35 is away from the card slot 32, so that the first pipe 3 is unblocked.
