Description

Technical Field

[0001] This invention relates to the field of high-pressure outer cylinder machining of gas turbines, and in particular to a boring and milling machine tool for machining high-pressure outer cylinders of gas turbines. Background Technology

[0002] The high-pressure outer cylinder of a gas turbine is one of its core components. Its design, manufacturing, and performance directly affect the overall efficiency, reliability, and service life of the gas turbine. With breakthroughs in high-temperature materials and intelligent cooling technologies, the high-pressure outer cylinder will evolve towards higher efficiency, longer lifespan, and lower maintenance costs in the future. The high-pressure outer cylinder requires hole machining during processing, necessitating the use of a boring and milling machine. Boring and milling is a composite machining technology combining boring and milling processes, achieving three or more axes of linkage through a CNC system to complete high-precision, high-efficiency machining.

[0003] In existing technologies, the boring and milling of high-pressure outer cylinders is usually carried out using general-purpose machine tools or customized tooling. However, due to the large size and weight of the workpiece, it is impossible to accurately support the high-pressure outer cylinder according to the bottom outline of the workpiece during the support and fixation process. This results in insufficient support in some areas or the center surface of the fixed high-pressure outer cylinder being not level. Consequently, the high-pressure outer cylinder is prone to vibration during the machining process, causing hole position deviations and reducing the machining accuracy of the high-pressure outer cylinder. Therefore, it is necessary to propose a boring and milling machine tool for machining high-pressure outer cylinders of gas turbines to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a boring and milling machine tool for machining high-pressure outer cylinders of gas turbines, in order to solve the problem mentioned in the background art that the existing technology cannot accurately support the bottom outline of the workpiece, resulting in insufficient local support or an uneven center surface of the fixed high-pressure outer cylinder, which in turn easily leads to vibration of the high-pressure outer cylinder during machining, causing hole position deviation and reducing the machining accuracy of the high-pressure outer cylinder.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A boring and milling machine tool for machining the high-pressure outer cylinder of a gas turbine includes a support table, a machining center located at the rear of the support table, a sleeve fixedly mounted on the top of the support table, a slide rod slidably mounted inside the sleeve, the top of the slide rod extending out of the sleeve and fixedly connected to a sleeve, a bolt inserted into the outside of the sleeve and into the slide rod, a stud threaded inside the sleeve, the top of the stud extending out of the sleeve and fixedly connected to a support block, and a tool for machining the high-pressure outer cylinder on the rear of the sleeve. The cylinder limiting rear clamping component; the top of the support platform on the front side of the sleeve one is fixedly connected to the sleeve two via a support plate. A movable rod is slidably installed inside the sleeve two. The top of the movable rod extends out of the interior of the sleeve two and is fixedly connected to the sleeve two. A fixing bolt is inserted into the outside of the sleeve two and is inserted into the interior of the movable rod. A threaded post is installed inside the sleeve two. The top of the threaded post extends out of the interior of the sleeve two and is fixedly connected to the support block two. A front clamping component for limiting the high-pressure outer cylinder is provided on the rear side of the sleeve two.

[0007] Through the interlocking of structures such as Sleeve 1 and Sleeve 2, and Sleeve 1 and Sleeve 2, with several slots matching the shapes of the plug and fixing pin respectively opened inside the sliding rod and the movable rod, it is convenient to insert the plug into different slots. This allows for adjustment of the distance between Sleeve 1 and Sleeve 1 and Sleeve 2 and Sleeve 2, and coarse adjustment of the height of Support Block 1 and Support Block 2. By rotating Support Block 1 and Support Block 2, the stud and threaded column can be rotated inside Sleeve 1 and Sleeve 2 respectively, thereby enabling precise adjustment of the height of Support Block 1 and Support Block 2 to accommodate high-pressure outer cylinders of different volumes and heights. This facilitates precise support according to the bottom contour of the workpiece, reducing the possibility of vibration during the machining of the high-pressure outer cylinder by the machining center.

[0008] A further improvement of the technical solution of the present invention is that: the rear clamping component includes a fixing plate, the front side of the fixing plate is fixedly connected to the sleeve, a threaded rod is installed in the internal thread of the fixing plate, the top of the threaded rod extends out of the interior of the fixing plate and is rotatably connected to a fixing block through a bearing, and a pressure block is provided inside the fixing block.

[0009] In the above technical solution, the cooperation between the rear clamping components allows the fixed block to move upward by rotating the threaded rod, thus moving the pressure block into the high-pressure outer cylinder and ensuring that the bottom of the pressure block fits against the inner wall of the high-pressure outer cylinder, thereby creating a clamping effect on the high-pressure outer cylinder from the rear.

[0010] A further improvement of the technical solution of the present invention is that: a spring is fixedly installed on the rear side of the pressure block, the rear side of the spring is fixedly connected to the inner wall of the fixed block, the top of the pressure block has an inclined surface that slopes towards the bottom of the front side, and the front side of the pressure block extends out of the interior of the fixed block.

[0011] By adopting the above technical solution, by setting a spring and opening an inclined surface on the top of the pressure block, during the process of the pressure block moving to the top, the tangent of the pressure block first contacts the surface of the high-pressure outer cylinder. At this time, the pressure block is squeezed by the high-pressure outer cylinder and can shrink into the fixed block. After the pressure block moves into the high-pressure outer cylinder, the reaction force of the spring can automatically push the pressure block into the interior of the fixed block, so that the pressure block is stuck into the interior of the high-pressure outer cylinder, limiting the high-pressure outer cylinder. There is no need for the operator to manually move the pressure block, reducing the operation steps and improving work efficiency.

[0012] A further improvement of the technical solution of the present invention is that: an installation plate 1 is fixedly installed on the outside of the fixing block, and a screw 2 is threadedly connected inside the installation plate 1. The front side of the screw 2 extends out of the interior of the installation plate 1 and is rotatably mounted with a limit plate through a bearing. The top of the limit plate is in contact with the fixing block.

[0013] In the above technical solution, by rotating the second screw, the limiting plate is simultaneously driven to come into contact with and be pressed against the surface of the high-pressure outer cylinder, thereby limiting the high-pressure outer cylinder from the rear, further reducing the force of the drill bit on the high-pressure outer cylinder in the machining center and improving the vibration resistance during machining.

[0014] A further improvement of the technical solution of the present invention is that: the front clamping component includes a connecting plate, the rear side of the connecting plate is fixedly connected to the sleeve two, a lead screw is installed in the internal thread of the connecting plate, the top of the lead screw extends out of the interior of the connecting plate and is rotatably connected to a connecting block through a bearing, and a limit block is provided inside the connecting block.

[0015] Using the above technical solution, through the cooperation between the front clamping components, the connecting block can be moved to the top by rotating the lead screw, so that the limiting block moves into the high-pressure outer cylinder, and ensures that the bottom of the limiting block is in contact with the inner wall of the high-pressure outer cylinder, forming a clamping effect on the high-pressure outer cylinder from the front side.

[0016] A further improvement of the technical solution of the present invention is that: a second spring is fixedly installed on the front side of the limiting block, the front side of the second spring is fixedly connected to the inner wall of the connecting block, the top of the limiting block is provided with a slope that slopes to the rear side, and the rear side of the limiting block extends out of the interior of the connecting block.

[0017] By adopting the above technical solution, by setting a second spring and opening an inclined surface on the top of the limiting block, during the process of the limiting block moving to the top, the inclined surface of the limiting block first contacts the surface of the high-pressure outer cylinder. At this time, the limiting block is squeezed by the high-pressure outer cylinder and can retract into the connecting block. After the limiting block moves into the high-pressure outer cylinder, the reaction force of the second spring can automatically push the limiting block into the interior of the fixed block, so that the limiting block is locked into the interior of the high-pressure outer cylinder, limiting the high-pressure outer cylinder. There is no need for the operator to manually move the limiting block, reducing the operation steps and improving work efficiency.

[0018] A further improvement of the technical solution of the present invention is that: a second mounting plate is fixedly installed on the outside of the connecting block, a first screw is threadedly connected to the inside of the second mounting plate, the rear side of the first screw extends out of the inside of the second mounting plate and is rotatably mounted with a baffle through a bearing, and the top of the baffle is in contact with the connecting block.

[0019] In the above technical solution, by rotating screw one, the baffle is simultaneously driven to come into contact with and squeeze the surface of the high-pressure outer cylinder, thereby limiting the high-pressure outer cylinder from the front, further reducing the force of the drill bit on the high-pressure outer cylinder in the machining center, and improving the vibration resistance during machining.

[0020] A further improvement of the technical solution of the present invention is that: a support rod is hinged to the top of the support platform on the inner side of the sleeve and the support plate, and a top block is slidably installed on the top of the support platform on the rear side of the support rod through a hydraulic rod 2. The top of the top block is pressed against the surface of the support rod. A fixing frame is fixedly installed on the top of the support platform on the periphery of the support rod, and a stop block is slidably connected to the rear side of the fixing frame through a hydraulic rod 1. The rear side of the stop block is pressed against the surface of the support rod.

[0021] The above technical solution involves setting up a support rod and a corresponding structure. By controlling the hydraulic rod two to move the top block upwards, the support rod can be pushed and rotated upwards. The tilt angle of the support rod can be adjusted so that the top and rear sides of the support rod are in contact with the surface of the high-pressure outer cylinder, providing auxiliary support for the high-pressure outer cylinder. Then, the hydraulic rod one moves the abutment block, causing the abutment block to contact and press against the surface of the support rod, thereby limiting the support rod and reducing the force of the drill bit in the machining center on the high-pressure outer cylinder, thus improving the vibration resistance during machining.

[0022] In summary, due to the adoption of the above technical solutions, the technical progress achieved by this invention compared to the prior art is as follows:

[0023] 1. This invention provides a boring and milling machine tool for machining high-pressure outer cylinders of gas turbines. Through the mutual cooperation between the sleeve one and sleeve two and other structures, and by opening several slots inside the slide rod and movable rod respectively that match the shape of the plug and the fixing plug, the height of the support block one and the support block two can be roughly adjusted. By rotating the stud and the threaded column, the height of the support block one and the support block two can be precisely adjusted to adapt to high-pressure outer cylinders of different volumes and heights. This facilitates precise support according to the bottom outline of the workpiece and reduces the possibility of vibration during the machining of the high-pressure outer cylinder.

[0024] 2. This invention provides a boring and milling machine tool for machining the high-pressure outer cylinder of a gas turbine. Through the cooperation between the rear clamping component and the front clamping component, the fixed block and the connecting block are moved to the top by rotating the threaded rod and the lead screw, respectively, so that the pressure block and the limiting block move into the high-pressure outer cylinder, thereby forming a clamping effect on the high-pressure outer cylinder from the rear and front sides, improving the stability of the support for the high-pressure outer cylinder.

[0025] 3. This invention provides a boring and milling machine tool for machining the high-pressure outer cylinder of a gas turbine. By setting a support rod and a corresponding structure, the tilt angle of the support rod can be adjusted and limited by controlling hydraulic rod two and hydraulic rod one to drive the top block and the stop block to move respectively. This allows the top and rear sides of the support rod to fit against the surface of the high-pressure outer cylinder, thus limiting the support rod. Furthermore, by rotating screw two and screw one, the limiting plate and the baffle plate are driven to limit the high-pressure outer cylinder from the rear and front sides respectively, thereby reducing the force of the drill bit in the machining center on the high-pressure outer cylinder and improving the vibration resistance during machining.

[0034] The present invention will be further described in detail below with reference to embodiments:

[0035] Example 1

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, this invention provides a boring and milling machine tool for machining the high-pressure outer cylinder of a gas turbine, including a support table 1. A machining center 2 is arranged on the rear side of the support table 1. A sleeve 4 is fixedly installed on the top of the support table 1. A slide rod 20 is slidably installed inside the sleeve 4. The top of the slide rod 20 extends out of the interior of the sleeve 4 and is fixedly connected to a sleeve 5. A plug 6 is inserted into the outside of the sleeve 4 and is inserted into the interior of the slide rod 20. A stud 21 is threaded inside the sleeve 5. The top of the stud 21 extends out of the interior of the sleeve 5 and is fixedly connected to a support block 22. A tool for machining the high-pressure outer cylinder is provided on the rear side of the sleeve 5. The rear clamping component for cylinder limiting; the top of the support platform 1 on the front side of sleeve 1 4 is fixedly connected to sleeve 2 17 via support plate 3. A movable rod 23 is slidably installed inside sleeve 2 17. The top of the movable rod 23 extends out of the interior of sleeve 2 17 and is fixedly connected to sleeve 2 18. A fixing bolt 19 is inserted into the outside of sleeve 2 17. The fixing bolt 19 is inserted into the interior of the movable rod 23. A threaded post 24 is threaded inside sleeve 2 18. The top of the threaded post 24 extends out of the interior of sleeve 2 18 and is fixedly connected to support block 2 25. A front clamping component for limiting the high-pressure outer cylinder is provided on the rear side of sleeve 2 18.

[0037] In this embodiment, through the mutual cooperation between the structures such as sleeve 4 and sleeve 5, and sleeve 17 and sleeve 18, and by opening several slots inside the slide rod 20 and the movable rod 23 that match the shape of the plug 6 and the fixing bolt 19, it is convenient to insert the plug 6 into different slots. This allows for adjustment of the distance between sleeve 5 and sleeve 4 and between sleeve 18 and sleeve 17, and coarse adjustment of the height of support block 22 and support block 25. By rotating support block 22 and support block 25, the stud 21 and threaded post 24 can be driven to rotate inside sleeve 5 and sleeve 18, respectively. This allows for precise adjustment of the height of support block 22 and support block 25 to accommodate high-pressure outer cylinders of different volumes and heights. This facilitates precise support according to the bottom outline of the workpiece and reduces the possibility of vibration during the machining of the high-pressure outer cylinder by the machining center 2.

[0038] Example 2

[0039] like Figure 2 , Figure 5 and Figure 6As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the rear clamping component includes a fixing plate 7, the front side of the fixing plate 7 is fixedly connected to the sleeve 5, a threaded rod 26 is threadedly installed inside the fixing plate 7, the top of the threaded rod 26 extends out of the interior of the fixing plate 7 and is rotatably connected to a fixing block 8 via a bearing, a pressure block 16 is provided inside the fixing block 8, a spring 27 is fixedly installed on the rear side of the pressure block 16, the rear side of the spring 27 is fixedly connected to the inner wall of the fixing block 8, and the top of the pressure block 16 has a bottom tilt towards the front side. The inclined surface of the pressure block 16 extends outward from the interior of the fixing block 8. A mounting plate 28 is fixedly installed on the outer side of the fixing block 8. A screw 29 is threadedly connected to the interior of the mounting plate 28. The front side of the screw 29 extends outward from the interior of the mounting plate 28 and is rotatably mounted with a limit plate 30 via a bearing. The top of the limit plate 30 is in contact with the fixing block 8. The front clamping component includes a connecting plate 31. The rear side of the connecting plate 31 is fixedly connected to the sleeve 18. A lead screw 32 is threadedly installed inside the connecting plate 31, and the top of the lead screw 32 extends outward from the connecting plate. Inside the connector 31, a connecting block 33 is rotatably connected via a bearing. A limiting block 35 is installed inside the connecting block 33. A second spring 34 is fixedly mounted on the front side of the limiting block 35, and the front side of the second spring 34 is fixedly connected to the inner wall of the connecting block 33. The top of the limiting block 35 has a sloped surface that slopes backwards to the bottom, and the rear side of the limiting block 35 extends out of the interior of the connecting block 33. A second mounting plate 36 is fixedly mounted on the outside of the connecting block 33. A first screw 10 is threadedly connected inside the second mounting plate 36, and the rear side of the first screw 10 extends out of the second mounting plate 36. Inside, a baffle 37 is rotatably mounted via a bearing. The top of the baffle 37 is in contact with the connecting block 33. A support rod 9 is hinged to the top of the support platform 1 on the inner side of the sleeve 4 and the support plate 3. A top block 15 is slidably mounted on the top of the support platform 1 on the rear side of the support rod 9 via a hydraulic rod 14. The top of the top block 15 presses against the surface of the support rod 9. A fixing frame 11 is fixedly mounted on the top of the support platform 1 on the periphery of the support rod 9. A stop block 13 is slidably connected to the rear side of the fixing frame 11 via a hydraulic rod 12. The rear side of the stop block 13 presses against the surface of the support rod 9.

[0040] In this embodiment, through the cooperation between the rear clamping components, the fixed block 8 can be moved upward by rotating the threaded rod 26, so that the pressure block 16 moves into the high-pressure outer cylinder, ensuring that the bottom of the pressure block 16 fits against the inner wall of the high-pressure outer cylinder, forming a clamping effect on the high-pressure outer cylinder from the rear. By setting the spring 27 and opening the inclined surface on the top of the pressure block 16, during the process of the pressure block 16 moving upward, the tangent of the pressure block 16 first contacts the surface of the high-pressure outer cylinder. At this time, the pressure block 16 can retract into the fixed block 8 under the pressure of the high-pressure outer cylinder. After the pressure block 16 moves into the high-pressure outer cylinder, the reaction force of the spring 27 can automatically push the pressure block 16 into the interior of the fixed block 8, so that the pressure block 16 is locked into the interior of the high-pressure outer cylinder, limiting the high-pressure outer cylinder. There is no need for the operator to manually move the pressure block 16, reducing the operation steps and improving work efficiency.

[0041] Through the cooperation between the front clamping components, rotating the lead screw 32 can drive the connecting block 33 to move upward, causing the limiting block 35 to move into the high-pressure outer cylinder, ensuring that the bottom of the limiting block 35 is in contact with the inner wall of the high-pressure outer cylinder, forming a clamping effect on the high-pressure outer cylinder from the front side; by setting the second spring 34 and opening the inclined surface on the top of the limiting block 35, during the process of the limiting block 35 moving upward, the inclined surface of the limiting block 35 first contacts the surface of the high-pressure outer cylinder. At this time, the limiting block 35 is squeezed by the high-pressure outer cylinder and can retract into the connecting block 33. After the limiting block 35 moves into the high-pressure outer cylinder, the reaction force of the second spring 34 can automatically push the limiting block 35 into the interior of the fixing block 8, so that the limiting block 35 is locked into the interior of the high-pressure outer cylinder, limiting the high-pressure outer cylinder. There is no need for the operator to manually move the limiting block 35, reducing the operation steps and improving work efficiency;

[0042] By setting up a support rod 9 and its cooperating structure, the hydraulic rod 14 drives the top block 15 to move upward, which pushes the support rod 9, causing it to rotate upward. This adjusts the tilt angle of the support rod 9, making its top and rear sides fit against the surface of the high-pressure outer cylinder, providing auxiliary support. The hydraulic rod 12 then drives the abutment block 13 to move, causing it to fit against and press against the surface of the support rod 9, thus limiting the support rod 9 and reducing the force exerted by the drill bit in the machining center 2 on the high-pressure outer cylinder, thereby improving the vibration resistance during machining. Furthermore, by rotating the screw 29 and screw 10, the limiting plate 30 and baffle 37 are simultaneously driven to fit against and press against the surface of the high-pressure outer cylinder, further limiting the high-pressure outer cylinder from the rear and front sides, further reducing the force exerted by the drill bit in the machining center 2 on the high-pressure outer cylinder and improving the vibration resistance during machining.

[0043] The working principle of the boring and milling machine tool used for machining the high-pressure outer cylinder of the gas turbine is explained in detail below.

[0044] like Figures 1-6 As shown, depending on the volume and height of the high-pressure outer cylinder, the operator can remove the insert 6 and the fixing bolt 19, and move the sliding rod 20 and the movable rod 23 to the top respectively. Then, the insert 6 and the fixing bolt 19 are reinserted into the sleeve 1 4 and the sliding rod 20, and the sleeve 2 17 and the movable rod 23 respectively, to initially adjust and limit the height of the support block 25. Then, the support block 1 22 and the support block 25 are rotated, which simultaneously drives the stud 21 and the threaded stud 24 to rotate inside the sleeve 1 5 and the sleeve 2 18 respectively, to further precisely adjust the height of the support block 1 22 and the support block 25 to adapt to high-pressure outer cylinders of different volumes and heights. After adjustment, the high-pressure outer cylinder is placed on top of the support block 1 22 and the support block 25. Then, the threaded rod 26 and the lead screw 32 are rotated respectively, which drives the fixing block 8 and the connecting block 33 to the top respectively, so that the pressure block 16 and the limiting block 35 move into the high-pressure outer cylinder. Then, the threaded rod 26 and screw 32 are rotated in the opposite direction, causing the bottom of the pressure block 16 and the limiting block 35 to press against the inner wall of the high-pressure outer cylinder, clamping the high-pressure outer cylinder. Then, the hydraulic rod 12 is controlled to drive the abutment block 13 to separate from the surface of the support rod 9. Then, the hydraulic rod 14 is controlled to drive the top block 15 to move to the top, causing the support rod 9 to rotate to the top, so that the top and rear side of the support rod 9 are in contact with the surface of the high-pressure outer cylinder, providing auxiliary support for the high-pressure outer cylinder. Then, the hydraulic rod 12 is controlled to drive the abutment block 13 to be in contact with and press against the surface of the support rod 9, thereby limiting the support rod 9. Finally, the screw 29 and screw 10 are rotated, respectively driving the limiting plate 30 and the baffle 37 to be in contact with and press against the surface of the high-pressure outer cylinder, limiting the high-pressure outer cylinder from the rear and front sides, thereby reducing the force of the drill bit in the machining center 2 on the high-pressure outer cylinder and improving the vibration resistance during machining.

[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
