Description

Technical Field

[0001] The invention relates to the technical field of laser processing, in particular to a processing device for cooling air film holes of engine components. Background Art

[0002] In the manufacturing process of aircraft engines, film holes are important structures for achieving efficient cooling of key components and are widely used in core components in high-temperature environments. Through film cooling technology, film holes can guide the cooling airflow to form a thin layer of air film on the surface of the component, thereby effectively reducing the direct thermal shock of the high-temperature airflow on the component. With the continuous development of aircraft engine technology, the design of film holes has become more and more complex, and the requirements for processing accuracy and quality have become higher and higher. At present, laser drilling technology has become the mainstream method for processing film holes due to its high-precision and non-contact processing characteristics. However, the existing laser drilling equipment still has some technical limitations in practical applications, especially the problem of the inability to flexibly adjust the laser angle during the processing process.

[0003] Existing air film hole laser processing equipment usually adopts a design with a fixed laser emission angle. When processing air film holes at different angles, the operator can only manually adjust the position of the workpiece clamp or reposition the workpiece to achieve the required laser processing angle. This operation method brings many inconveniences and problems. First of all, since the laser angle cannot be adjusted freely, parts with complex shapes need to adjust the workpiece position multiple times to achieve all-round processing, which not only increases the difficulty of operation, but also prolongs the processing time, resulting in a significant decrease in processing efficiency. Especially in continuous production or batch processing, frequent manual adjustments will significantly affect the rhythm and output of production.

[0004] Secondly, frequent adjustments to the workpiece position can easily lead to a decrease in machining accuracy. Each manual adjustment of the workpiece can easily lead to slight displacement or deviation, especially when multiple adjustments are made during the machining process. The accumulated errors can easily lead to the machining accuracy of the air film hole failing to meet the design requirements. For aircraft engine components with extremely high requirements, errors can easily have a significant impact on the performance and service life of the components. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a processing equipment for cooling air film holes of engine components, which solves the problem that the existing air film hole laser processing equipment cannot flexibly adjust the laser angle, resulting in the need to frequently adjust the workpiece position during processing, affecting the processing efficiency and accuracy, and limiting the processing of complex components.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a processing equipment for cooling air film holes of engine components, comprising a workbench and a three-axis movable module installed on the top of the workbench for multi-axis movement, the working end of the three-axis movable module is installed with a mounting seat, an angle adjustment component is installed inside the mounting seat, a laser is installed at the bottom of the angle adjustment component, a laser head is detachably connected to the bottom of the laser, and a clamping component for fixing the workpiece and a cooling component for cooling the workpiece are also installed on the top of the workbench.

[0007] Preferably, the angle adjustment assembly includes motor 1 and motor 2, both of which are installed on the outside of the mounting seat, the output end of motor 1 is fixedly connected to toggle plate 1, the output end of motor 2 is fixedly connected to toggle plate 2, the inner side of toggle plate 2 is rotatably connected to a connecting ball, the outer side of the connecting ball is rotatably connected to the inner side of toggle plate 1, and the laser is installed at the bottom of the connecting ball.

[0008] Preferably, a connecting seat is fixedly connected to the bottom of the laser, a mounting groove is provided on the outer side of the connecting seat, a spring is fixedly connected to the inside of the connecting seat, and a connecting block is fixedly connected to the top of the laser head, and the shape of the connecting block and the mounting groove are adapted to each other.

[0009] Preferably, a connection groove is provided on the top of the laser head, and the connection seat is clamped in the middle of the connection groove.

[0010] Preferably, the clamping assembly includes a motor three, the motor three is fixedly connected to the top of the workbench, the output end of the motor three is fixedly connected to a chuck, and the workpiece is clamped in the middle of the chuck.

[0011] Preferably, the cooling component includes a water tank, which is fixedly connected to the bottom of the workbench, a water pump is fixedly connected to the outside of the water tank, an output end of the water pump is fixedly connected to a water distribution pipe, and an end of the water distribution pipe is fixedly connected to a universal cooling pipe.

[0012] Preferably, a plurality of drain holes are provided in the middle of the workbench, the water tank is located below the drain holes, and the drain holes are connected to the inside of the water tank.

[0013] Preferably, a filter screen is slidably connected to the middle of the workbench, and the water drop hole is located between the filter screen and the water tank.

[0014] Preferably, a heat dissipation fin is fixedly connected to the outside of the water tank, a heat dissipation fan is fixedly connected to the outside of the workbench, and the direction of the heat dissipation fan corresponds to the arrangement direction of the heat dissipation fin.

[0015] Preferably, a water collecting trough is also provided on the top of the workbench, and the water drop hole is located in the middle of the water collecting trough.

[0016] Working principle: When processing the air film hole of the engine parts, install the parts to be processed between the chucks, and then adjust the position of the mounting seat by driving the three-axis moving module to adjust the position of the laser and the laser head to ensure that the laser head is aligned with the workpiece. When the workpiece needs to be processed in an inclined direction, the first motor can be driven to drive the toggle plate to rotate, and then the connecting ball can be driven to rotate in the horizontal direction, and then the second motor can be driven to drive the toggle plate to rotate, thereby driving the connecting ball to rotate in the vertical direction. With the cooperation of the first motor and the second motor, the free adjustment of the connecting ball is realized, thereby changing the direction of the laser and the laser head, and after cooperating with the three-axis moving module, the multi-angle laser processing operation of the workpiece can be realized. After processing one side of the workpiece, the third motor can drive the chuck to rotate, which can drive the workpiece to flip so as to process the air film hole on the next side. There is no need to frequently adjust the clamping position of the workpiece, which greatly improves work efficiency.

[0017] Secondly, a certain amount of slag will be generated during the laser processing process. The slag will accumulate on the workpiece and easily affect the processing and reduce the quality of the workpiece. For this reason, during the laser processing process, the water pump is driven to pump out the water inside the water tank and transport it to the water distribution pipe, and then dispersed into each universal cooling pipe through the water distribution pipe. After the water is sprayed out from the other end of the universal cooling pipe, the workpiece can be cleaned to avoid the influence of slag. At the same time, while cleaning the slag, the workpiece is also cooled to further ensure the quality of the processed parts. The sprayed water will fall to the top of the workbench, and then be collected through the water collection trough and fall down from the drain hole, and then fall to the top of the filter. After filtering through the filter, it returns to the water tank, thereby realizing the recycling of water resources, and after a period of use, the filter can be pulled out to clean the filtered slag.

[0018] At the same time, cooling fins are installed on the outside of the water tank. When water cools the workpiece, it will absorb more heat. After this heat enters the water tank, it cannot be discharged quickly. After adding cooling fins, the heat inside the water tank can be conducted through the cooling fins, and then the heat can be discharged in cooperation with the cooling fan, thereby ensuring the continuous cooling effect of the water body and making it more convenient to use.

[0019] Finally, because the processing requirements of each workpiece are different, when the processing requirements need to be changed, the laser head can be lifted up, the spring can be squeezed, the connecting block can also be moved upward, and then the laser head can be rotated along the direction of the installation groove. When the connecting block reaches the exit section of the installation groove, the laser head can be removed by pulling down to complete the disassembly of the laser head. Then the new laser head can be installed by reverse operation. In this way, the laser head can be quickly replaced to adapt to different processing needs and greatly improve processing efficiency.

[0020] The present invention provides a processing device for cooling air film holes of engine parts. It has the following beneficial effects:

[0021] 1. The present invention uses motor 1 and motor 2 to drive the toggle plate 1 and the toggle plate 2 to work respectively, thereby changing the angle of the connecting ball, thereby adjusting the angle of the laser and the laser head, so as to perform air film hole processing operations on different arc surfaces and different directions of the workpiece, without frequently adjusting the workpiece clamping position, greatly improving the processing efficiency.

[0022] 2. The present invention can quickly install and disassemble the laser head through the mutual cooperation of the connecting block, the mounting groove, the spring and other structures, thereby facilitating the replacement of different laser heads according to the processing requirements of different air film holes and improving the processing efficiency of the device.

[0023] 3. The present invention utilizes a water pump to draw out the water inside the water tank and spray it toward the workpiece, so as to cool the workpiece and take out the slag at the same time, so as to ensure the quality of the processed workpiece. The slag is then filtered through a filter to ensure that the water can be recycled, and the water is cooled using cooling fins and a cooling fan to ensure a continuous cooling effect on the workpiece.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example:

[0033] Please see attached Figure 1 -Attached Figure 3 An embodiment of the present invention provides a processing device for cooling air film holes of engine components, including a workbench 1 and a three-axis movable module 2 installed on the top of the workbench 1 for multi-axis movement. The working end of the three-axis movable module 2 is installed with a mounting seat 3. By driving the three-axis movable module 2 to work, the mounting seat 3 is driven to move in multiple directions such as left and right, front and back, and up and down, so as to process different positions of the workpiece. Since the three-axis movable module 2 is a prior art, it will not be described in detail here. An angle adjustment component is installed inside the mounting seat 3, and a laser 9 is installed at the bottom of the angle adjustment component. The direction of the laser 9 can be changed by the angle adjustment component to facilitate the laser processing operation of the air film holes under different curved surfaces of the workpiece.

[0034] Please see attached Figure 3The angle adjustment component includes a motor 1 4 and a motor 2 7. The motor 1 4 and the motor 2 7 are both installed on the outside of the mounting seat 3. The output end of the motor 1 4 is fixedly connected to a toggle plate 1 5. The output end of the motor 2 7 is fixedly connected to a toggle plate 2 8. The inner side of the toggle plate 2 8 is rotatably connected to a connecting ball 6. The outer side of the connecting ball 6 is rotatably connected to the inner side of the toggle plate 1 5. The motor 1 4 and the motor 2 7 are both servo motors, which are used to accurately adjust the rotation angle of the connecting ball 6. The laser 9 is installed at the bottom of the connecting ball 6. The bottom of the laser 9 is detachably connected to a laser head 10. The driving motor 1 4 drives the toggle plate 1 5 to rotate, so as to drive the connecting ball 6 to rotate in the horizontal direction. The driving motor 2 7 drives the toggle plate 2 8 to rotate, so as to drive the connecting ball 6 to rotate in the vertical direction. Under the mutual cooperation of the motor 1 4 and the motor 2 7, the free adjustment of the connecting ball 6 is realized, thereby changing the direction of the laser 9 and the laser head 10. In this way, the air film hole processing operation of different angles on different arc surfaces and different positions of the workpiece is realized, without the need to frequently adjust the clamping position, which greatly improves the processing efficiency.

[0035] Please see attached Figure 3 -Attached Figure 5 , a connecting seat 13 is fixedly connected to the bottom of the laser 9, a mounting groove 14 is opened on the outside of the connecting seat 13, a spring 15 is fixedly connected inside the connecting seat 13, and a connecting block 12 is fixedly connected to the top of the laser head 10, and the shapes of the connecting block 12 and the mounting groove 14 are adapted to each other. When the laser head 10 needs to be installed at the bottom of the laser 9, it is only necessary to align the connecting block 12 with the entrance of the mounting groove 14, and then push the laser head 10 upward. At this time, the spring 15 is squeezed by the laser head 10 and contracts. At the same time, the connecting block 12 also reaches the middle of the mounting groove 14, and then the laser head 10 is rotated along the direction of the mounting groove 14. After the connecting block 12 reaches the end of the mounting groove 14, the laser head 10 is released. At this time, the spring 15 will rebound, thereby pushing the connecting block 12 into the clamping part of the mounting groove 14, thereby completing the connection between the laser head 10 and the laser 9. The operation is simple and the installation efficiency is greatly improved. The separation of the laser head 10 and the laser 9 can be completed by reverse operation. When processing different air film holes of the workpiece, different types of laser heads 10 can be replaced through this operation to meet different processing needs. A connection groove 11 is provided on the top of the laser head 10, and a connection seat 13 is snapped in the middle of the connection groove 11. During the installation of the laser 9 and the laser head 10, the connection groove 11 will also be snapped with the connection seat 13 to ensure the stability of the installation and the sealing after installation.

[0036] Please see attached Figure 1A clamping assembly for fixing the workpiece and a cooling assembly for cooling the workpiece are also installed on the top of the workbench 1. The clamping assembly includes a motor 25. The motor 25 is fixedly connected to the top of the workbench 1. The output end of the motor 25 is fixedly connected to a chuck 26. The workpiece is clamped in the middle of the chuck 26. After the workpiece is installed in the middle of the chuck 26, the three-axis moving module 2, the laser 9, and the laser head 10 can be driven to perform air film hole processing on the workpiece. After completing the processing of one side or one angle of the workpiece, the motor 25 can be driven to drive the chuck 26 to rotate, thereby driving the workpiece to rotate synchronously to perform the air film hole processing operation on the next side and the next angle.

[0037] Please see attached Figure 1 and attached Figure 6 The cooling component includes a water tank 16, which is fixedly connected to the bottom of the workbench 1. A water pump 17 is fixedly connected to the outside of the water tank 16. A water distribution pipe 18 is fixedly connected to the output end of the water pump 17. A universal cooling pipe 19 is fixedly connected to the end of the water distribution pipe 18. During the laser processing, the water pump 17 is driven to pump out the water inside the water tank 16 and transport it to the inside of the water distribution pipe 18, and then the water is dispersed into each universal cooling pipe 19 through the water distribution pipe 18. After the water is sprayed out from the other end of the universal cooling pipe 19, the workpiece can be cleaned to avoid the influence of slag.

[0038] Please see attached Figure 6 There are multiple groups of water holes 20 in the middle of the workbench 1, and the water tank 16 is located below the water holes 20, and the water holes 20 are connected to the inside of the water tank 16. The sprayed water will fall to the top of the workbench 1, and then be collected into the inside of the water tank 16 through the water holes 20. A filter screen 21 is slidably connected in the middle of the workbench 1, and the water holes 20 are located between the filter screen 21 and the water tank 16. When the waste water passes through the water holes 20, it will be blocked by the filter screen 21. At this time, the slag carried by the waste water will be filtered on the upper surface of the filter screen 21 to prevent the slag from entering the inside of the water tank 16. After a period of use, the filter screen 21 can be pulled out to clean the filtered slag.

[0039] Please see attached Figure 6The outside of the water tank 16 is fixedly connected with a heat dissipation fin 22, and the outside of the workbench 1 is fixedly connected with a heat dissipation fan 24. The direction of the heat dissipation fan 24 corresponds to the arrangement direction of the heat dissipation fin 22. When water cools the workpiece, it will absorb more heat. After this heat enters the inside of the water tank 16, it cannot be quickly discharged. After adding the heat dissipation fin 22, the heat inside the water tank 16 can be conducted through the heat dissipation fin 22, and then after cooperating with the heat dissipation fan 24, the heat is discharged, thereby ensuring the continuous cooling effect of the water body, and it is more convenient to use. A water collection tank 23 is also provided on the top of the workbench 1, and the water drop hole 20 is located in the middle of the water collection tank 23. The wastewater on the upper part of the workbench 1 is collected through the water collection tank 23 to better perform the filtering operation.
