Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, in particular to cutting processing equipment for a steam turbine cylinder. Background Art

[0002] With the transformation of the global industrial system towards digitalization and intelligence, the so-called Industry 4.0 and the advent of the era of intelligent manufacturing, unprecedented requirements have been put forward for the high precision, high efficiency and automated processing capabilities of processing equipment. This trend is not only reflected in the transformation and upgrading of traditional manufacturing industries, but also drives the research and development and application of a new generation of high-precision processing equipment. In the manufacturing of key components such as turbine cylinders, cutting processing is a crucial step, which directly determines the performance and service life of the turbine.

[0003] In actual use, cutting processing equipment still has many defects. For example, traditional equipment is difficult to achieve high-precision positioning and clamping during the cutting process, resulting in limited product processing accuracy. At the same time, existing cutting processing equipment lacks effective dust and debris management, resulting in high equipment maintenance costs, poor working environment, and frequent manual intervention. It not only increases labor costs, but also reduces the ability of continuous production. Therefore, it is necessary to design cutting processing equipment for turbine cylinders. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a cutting processing equipment for a steam turbine cylinder.

[0005] The present invention is implemented by the following technical scheme: a cutting processing device for a steam turbine cylinder comprises a processing assembly, the processing assembly comprises a cavity, a first support frame is fixedly mounted on the top of the processing assembly, a cutting machine is fixedly mounted on the upper surface of the first support frame, a cutting spindle is fixedly mounted on the output end of the cutting machine, a cutting head is fixedly mounted on the outer surface of the cutting spindle, and further comprises:

[0006] A rotating assembly, the rotating assembly comprising a driving motor, a first connecting rod being fixedly mounted on an output end of the driving motor, a supporting rod being fixedly mounted on an end of the first connecting rod away from the driving motor, and a cutting table being fixedly mounted on the top of the supporting rod;

[0007] A clamping assembly, the clamping assembly comprising a servo motor, a plurality of sets of sliding clamps are slidably mounted on the output end of the servo motor, and a positioning seat is fixedly mounted on the top of the sliding clamp;

[0008] The cleaning component comprises a reciprocating drive toothed disc, a second connecting rod is fixedly mounted on the top of the reciprocating drive toothed disc, a push rod is slidably mounted on the top of the second connecting rod, and a push plate is fixedly mounted on the front section of the push rod.

[0009] As a further improvement of the above scheme, a second support frame is fixedly installed on the top of the processing component, a push rod is fixedly installed inside the second support frame, a debris collection box is fixedly installed on the upper surface of the processing component, and a guide groove is opened on the upper surface of the processing component.

[0010] Through the above technical solution, the second support frame can support and guide the movement of the push rod, the material collection phase can be used to collect metal debris, and the guide groove can ensure the stability of the cutting table when it rotates.

[0011] As a further improvement of the above scheme, a third support frame is fixedly installed on the bottom of the cutting table, and the end of the third support frame away from the cutting table is slidably installed inside the guide groove. A fixed base is fixedly installed on the four sides of the bottom of the cutting table, and a multi-directional threaded adjustment rod group is fixedly installed inside the fixed base.

[0012] Through the above technical solution, the multi-directional threaded adjustment rod group is provided with two groups of bidirectional threaded rods, which are composed of a transverse bidirectional screw and a longitudinal bidirectional screw, ensuring that the four groups of sliding clamps on the surface of the multi-directional threaded adjustment rod group can be driven.

[0013] As a further improvement of the above solution, a support bearing is fixedly installed on the top of the first connecting rod, a support platform is fixedly installed on the outer surface of the support bearing, a servo motor is rotatably installed inside the support bearing, and a second driving gear disc is fixedly installed on the output end of the servo motor.

[0014] Through the above technical solution, the setting of the support bearing ensures the stability of the servo motor during operation, and the support platform further enhances the stability of the structure, improves the stability of the overall structure and extends the service life of the equipment.

[0015] As a further improvement of the above solution, a gear bar is slidably installed on the outer surface of the second driving gear plate, and the gear bar is meshed between the second driving gear plates. There are four gear bars, and a sliding clamp is fixedly installed on the top of the gear bar.

[0016] Through the above technical solution, the linkage control of the cutting table rotation and the cleaning component is realized, and the fine-tuning toothed disc cooperates with the reciprocating drive toothed disc to ensure accurate cutting and cleaning actions.

[0017] As a further improvement of the above scheme, the sliding clamp is arranged on the outer surface of the multi-directional threaded adjustment rod group, a positioning seat is fixedly installed on the top of the sliding clamp, a limiting baffle is fixedly installed on the outer surface of the positioning seat, and a telescopic dust cover is fixedly installed on the front and rear ends of the sliding clamp.

[0018] Through the above technical solution, the sliding clamp moves along the multi-directional threaded adjustment rod group, and the positioning seat and the limit baffle work together to achieve precise clamping of the turbine cylinder and improve processing stability. The retractable dust cover can prevent debris from entering the equipment during the cutting process and reduce maintenance costs.

[0020] Through the above technical solution, the first driving toothed disc is engaged with the fine-tuning toothed disc, thereby realizing precise rotation control of the cutting table and ensuring the stability and accuracy of the cutting process.

[0021] As a further improvement of the above scheme, a reciprocating drive gear disc is rotatably installed inside the cavity, the reciprocating drive gear disc is meshed with the fine-tuning gear disc, a second connecting rod is fixedly installed on the top of the reciprocating drive gear disc, and a fourth support frame is fixedly installed on the end of the second connecting rod away from the reciprocating drive gear disc.

[0022] As a further improvement of the above solution, a third connecting rod is rotatably mounted on the top of the fourth support frame, and one end of the third connecting rod away from the fourth support frame is rotatably mounted inside the mounting seat, and a push rod is fixedly mounted on the front end of the mounting seat.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention drives the second driving gear plate to rotate by a servo motor. Since the second driving gear plate is meshed with the gear bar, the sliding clamp can be driven to slide under the limit of the multi-directional threaded adjustment rod group. When the servo motor rotates forward, it drives the gear bar to shrink, and can synchronously drive the positioning seat to shrink. Conversely, when the servo motor reverses, the positioning seat can expand outward. Through the drive of the servo motor, the positioning seat can be driven to clamp the turbine cylinder to ensure the stability of the cutting process.

[0025] When the driving motor of the present invention drives the first connecting rod to rotate, the first driving gear disc will drive the fine-tuning gear disc and the reciprocating driving gear disc to rotate. At this time, the rack on the left side of the fine-tuning gear disc will resist the reciprocating driving gear disc, ensuring that the reciprocating driving gear disc can move back and forth, driving the push rod to retract and retract in the second support frame, ensuring that after the cutting process of the cylinder is completed, the metal debris on the surface of the cutting table can be pushed to the debris collection box by the push plate, thereby realizing automatic cleaning of the equipment surface and improving the processing efficiency and the cleanliness of the working environment.

[0042] When the cutting table 205 rotates, the third support frame 207 is slidably installed in the guide groove 108 to support the cutting table 205 when it rotates.

[0043] A third support frame 207 is fixedly installed at the bottom of the cutting table 205, and one end of the third support frame 207 away from the cutting table 205 is slidably installed inside the guide groove 108. A fixed base 208 is fixedly installed on the four sides of the bottom of the cutting table 205, and a multi-directional threaded adjustment rod group 209 is fixedly installed inside the fixed base 208.

[0045] A gear bar 303 is slidably mounted on the outer surface of the second driving gear plate 302 . The gear bar 303 is meshed with the second driving gear plate 302 . There are four gear bars 303 . A sliding clamp 304 is fixedly mounted on the top of the gear bar 303 .

[0046] The sliding clamp 304 is arranged on the outer surface of the multi-directional threaded adjustment rod group 209, and a positioning seat 305 is fixedly installed on the top of the sliding clamp 304, and a limit baffle 306 is fixedly installed on the outer surface of the positioning seat 305. The front and rear ends of the sliding clamp 304 are fixedly installed with a telescopic dust cover 206.

[0047] The steam turbine cylinder to be processed by cutting is placed on the surface of the cutting table 205, and the second driving gear disc 302 is driven to rotate by the servo motor 301. Since the second driving gear disc 302 is meshed with the gear bar 303, the sliding clamp 304 can be driven to slide under the limit of the multi-directional threaded adjustment rod group 209, and the fixed base 208 ensures that the multi-directional threaded adjustment rod group 209 is fixedly installed on the lower surface of the cutting table 205. When the servo motor 301 rotates forward, it drives the gear bar 303 to shrink, and can synchronously drive the positioning seat 305 to shrink. Conversely, when the servo motor 301 rotates reversely, the positioning seat 305 can expand outward. The servo motor 301 drives the positioning seat 305 to clamp the steam turbine cylinder, and the limit baffle 306 can further ensure the stability of the cutting process.

[0048] A first driving gear disc 203 is fixedly mounted on the bottom of the first connecting rod 202 , and a fine-tuning gear disc 109 is rotatably mounted on the inner wall of the cavity 101 . The first driving gear disc 203 is meshed with the fine-tuning gear disc 109 .

[0049] A reciprocating drive gear disc 401 is rotatably installed inside the cavity 101, and the reciprocating drive gear disc 401 is meshed with the fine-tuning gear disc 109. A second connecting rod 402 is fixedly installed on the top of the reciprocating drive gear disc 401, and a fourth support frame 403 is fixedly installed on the end of the second connecting rod 402 away from the reciprocating drive gear disc 401.

[0050] After the cutting process is completed, the metal debris cut off by the cutting head 105 will remain on the surface of the cutting table 205, and the telescopic dust cover 206 can prevent the debris from falling into the support platform 211 and the inside of the cavity 101 during the cutting process. After the cylinder is taken down from the top of the cutting table 205, the driving motor 201 drives the first connecting rod 202 to rotate, and the first driving gear disc 203 will drive the fine-tuning gear disc 109 and the reciprocating driving gear disc 401 to rotate. The fine-tuning gear disc 109 adjusts its position, and the rack on the left side thereof will press against the reciprocating driving gear disc 401, returning the position of the reciprocating driving gear disc 401 to the starting position, ensuring that the reciprocating driving gear disc 401 can perform reciprocating motion

[0051] A third connecting rod 404 is rotatably mounted on the top of the fourth supporting frame 403 . One end of the third connecting rod 404 away from the fourth supporting frame 403 is rotatably mounted inside the mounting seat 405 . A push rod 406 is fixedly mounted on the front end of the mounting seat 405 .

[0052] When the reciprocating drive gear disc 401 is performing a reciprocating motion, the second connecting rod 402 and the fourth support frame 403 provide support and connection. The third connecting rod 404 can be used to pull the push rod 406 to retract in the second support frame 106, and the mounting seat 405 can ensure the connection between the push rod 406 and the third connecting rod 404. The push rod 406 can be retracted in the second support frame 106 to drive the push rod 406 to be adjusted, ensuring that the metal debris on the surface of the cutting table 205 can be pushed to the debris collection box 107 by the push plate 407, so that the equipment can use the cleaning component 4 to automatically clean the surface of the cutting table 205, thereby improving the processing efficiency and the cleanliness of the working environment.

[0053] The implementation principle of the cutting processing equipment for the steam turbine cylinder in the embodiment of the present application is as follows: the steam turbine cylinder to be cut and processed is placed on the surface of the cutting table 205, and the second driving toothed disc 302 is driven to rotate by the servo motor 301. Since the second driving toothed disc 302 is meshed with the gear bar 303, the sliding clamp 304 can be driven to slide under the limit of the multi-directional threaded adjustment rod group 209, and the fixed base 208 ensures that the multi-directional threaded adjustment rod group 209 is fixedly installed on the lower surface of the cutting table 205. When the servo motor 301 rotates forward, the gear bar 303 is driven to shrink, and the positioning seat 305 can be driven to shrink synchronously. On the contrary, when the servo motor 301 is reversed, the positioning seat 305 can expand outward. The positioning seat 305 can be driven to clamp the steam turbine cylinder by the drive of the servo motor 301, and the limit baffle 306 can further ensure the stability of the cutting process.

[0054] After the clamping is completed, the cutting machine 103 drives the cutting spindle 104 to rotate, and the first support frame 102 can provide support for the cutting machine 103. At the same time, the rotating component 2 inside the processing component 1 starts to operate, and the driving motor 201 drives the first connecting rod 202 to rotate. Since the cutting table 205 and the first connecting rod 202 are connected by the support rod 204, the cutting table 205 can be driven to rotate, and the position of the cutting machine 103 is fixed. The inner wall of the cylinder can be cut by the cutting head 105. At the same time, when the cutting table 205 rotates, the third support frame 207 is slidingly installed in the guide groove 108. The third support frame 207 can be used to support the cutting table 205 when it rotates. At the same time, the support bearing 210 can ensure the installation of the support platform 211, and ensure that the support platform 211 supports the rotating component 2 and the clamping component 3;

[0055] After the cutting process is completed, the metal debris cut off by the cutting head 105 will remain on the surface of the cutting table 205, and the telescopic dust cover 206 can prevent the debris from falling into the support platform 211 and the inside of the cavity 101 during the cutting process. After the cylinder is taken down from the top of the cutting table 205, the driving motor 201 drives the first connecting rod 202 to rotate, and the first driving gear disc 203 drives the fine-tuning gear disc 109 and the reciprocating driving gear disc 401 to rotate. The fine-tuning gear disc 109 adjusts its position, and the rack on the left side thereof will press against the reciprocating driving gear disc 401, returning the position of the reciprocating driving gear disc 401 to the starting position, ensuring that the reciprocating driving gear disc 401 can perform reciprocating motion;

[0056] When the reciprocating drive gear disc 401 is performing a reciprocating motion, the second connecting rod 402 and the fourth support frame 403 provide support and connection. The third connecting rod 404 can be used to pull the push rod 406 to retract in the second support frame 106, and the mounting seat 405 can ensure the connection between the push rod 406 and the third connecting rod 404. The push rod 406 can be retracted in the second support frame 106 to drive the push rod 406 to be adjusted, ensuring that the metal debris on the surface of the cutting table 205 can be pushed to the debris collection box 107 by the push plate 407, so that the equipment can use the cleaning component 4 to automatically clean the surface of the cutting table 205, thereby improving the processing efficiency and the cleanliness of the working environment.

[0057] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
