[0001] The utility model relates to steam turbine technology field especially relates to a steam turbine rotor forge tool. BACKGROUND

[0002] In the manufacturing process of steam turbine rotor forge, the processing and maintenance of the rotor are the key links, and the traditional steam turbine rotor processing tool is often single-function, and when the rotor is processed or inspected, the angle of the rotor needs to be adjusted by external equipment, which is complicated and inefficient.

[0003] Some tools can only provide simple fixing support, and when the different sides of the rotor need to be processed, such as turning, drilling and flaw detection, it is difficult to conveniently realize the rotational positioning of the rotor, which seriously affects the processing precision and production efficiency; at the same time, after the rotor is forged, the surface will usually be attached with oxide skin, impurities and other foreign matters, and the existing cleaning method mostly relies on manual cleaning with tools, which not only has high labor intensity, but also is difficult to ensure the uniformity and thoroughness of cleaning, in addition, due to the lack of automatic cleaning device specially for the rotor, the rotor surface is easily damaged in the cleaning process, thereby affecting the quality and performance of the rotor.

[0004] Therefore, we propose a steam turbine rotor forge tool. CONTENT OF THE UTILITY MODEL

[0005] The main purpose of the utility model is to provide a steam turbine rotor forge tool, in order to prevent the rotor processing precision from being insufficient and the production efficiency from being low due to the functional limitation of the traditional tool, and to prevent the rotor surface quality from being damaged and the cleaning effect from being poor due to the defects of the manual cleaning method, so as to improve the overall process level and product quality in the manufacturing process of the steam turbine rotor forge, and the problems in the background art can be effectively solved.

[0006] In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is:

[0007] The utility model provides a steam turbine rotor forging frock, including the bottom plate, the upper end surface of bottom plate is fixedly connected with two two symmetries first fixed seat, support seat, wherein one side outer wall of one support seat is fixedly installed with motor, motor output is fixedly connected with driving gear, the top of two first fixed seat is all fixedly connected with first limit seat through first bolt, the inboard rotation of first limit seat and first fixed seat is connected with rotor, the outside of rotor near motor is provided with rotating device, rotating device includes fixed frame, the inner wall rotation of fixed frame is connected with threaded rod, the outside surface of threaded rod is threadedly connected with two clamping plates, the surface of clamping plate is slidably connected with fixed frame, one end of threaded rod is fixedly connected with handle, the side of fixed frame near first fixed seat is fixedly connected with first driven gear, and first driven gear is engaged with driving gear,

[0008] The support seat is rotatably connected with a second driven gear on the same side of the driving gear, and the second driven gear is engaged with the driving gear. The inner sides of the two support seats are rotatably connected by bearings to a lead screw, one end of the lead screw penetrates the support seat and is fixedly connected to the second driven gear. The outer part of the lead screw is threadedly connected to a sliding seat, and the sliding seat is provided with a cleaning device.

[0009] By adopting the above technical scheme, the motor serves as a power source, the driving gear at the output end thereof is engaged with the first driven gear in the rotating device, when the motor is started, the driving gear rotates to drive the first driven gear to rotate, the first driven gear is fixed to the fixed frame, the fixed frame forms a whole with the clamping plates through the internally rotatably connected threaded rods, and the whole rotates with the first driven gear. The two clamping plates are threadedly connected to the threaded rods and can slide in the fixed frame. Rotating the handle can rotate the threaded rods. Due to the threaded connection, the two clamping plates move towards or away from each other. When the clamping plates are close to and clamp the rotor, the whole rotating device driven by the motor can drive the rotor to rotate inside the first limit seat and the first fixed seat, facilitating the processing or inspection of the rotor at different angles.

[0010] The driving gear is also engaged with the second driven gear, and the second driven gear is fixed to one end of the lead screw. In this way, when the motor rotates, the second driven gear also rotates synchronously to drive the lead screw to rotate, ensuring the linkage of the whole frock. The lead screw is threadedly connected to the sliding seat. When the lead screw rotates under the drive of the second driven gear, the sliding seat moves along the axial direction of the lead screw. This lead screw transmission mode can realize accurate position control, so that the cleaning device on the sliding seat can accurately move to the position of the rotor that needs to be cleaned. During the forging of the rotor, some oxidation scales, impurities and the like need to be cleaned. The cleaning device can move on the lead screw along the length direction of the rotor to perform the cleaning work.

[0011] Further, the inner side of the top end of the first fixed seat and the inner side of the bottom end of the first limiting seat are both provided with an arc-shaped groove, a plurality of connecting shafts are arranged in the arc-shaped groove in a ring shape, and a plurality of rollers are rotatably connected to the outside of the plurality of connecting shafts, and the outer side of the roller is attached to the outer side of the rotor.

[0012] By adopting the above technical scheme, when the rotor is placed between the first fixed seat and the first limiting seat, the outer side of the rotor is tightly attached to the outer side of the plurality of rollers arranged in the arc-shaped groove in the inner side of the top end of the first fixed seat and the inner side of the bottom end of the first limiting seat. In the process of rotating the rotor, since the roller and the rotor are in rolling contact rather than sliding contact, according to the principle that the rolling friction coefficient is much smaller than the sliding friction coefficient, the frictional force received by the rotor during rotation is greatly reduced. The rolling friction coefficient may be only about 0.01-0.05, while the sliding friction coefficient may reach 0.1-0.3. In this way, the rotor can rotate more smoothly. The plurality of rollers are arranged in a ring shape in the arc-shaped groove. This arrangement can provide uniform support for the rotor. In the entire circumferential direction of the rotor, the plurality of rollers share the weight of the rotor and other forces generated during rotation, such as centrifugal force, to ensure the stability of the rotor during rotation and prevent the rotor from deforming or deviating due to excessive local stress.

[0014] By adopting the above technical scheme, the sliding seat is in sliding connection with the limiting rod during axial movement of the sliding seat driven by rotation of the lead screw. This provides a clear direction for the movement of the sliding seat, ensuring that the sliding seat can only move in the straight line direction defined by the limiting rod and cannot deviate, shake or twist. On the one hand, the limiting rod limits the freedom of the sliding seat in the direction perpendicular to the axial direction of the lead screw, preventing the sliding seat from moving laterally due to uneven stress and ensuring the accuracy of the movement path of the sliding seat, so that the sliding seat can accurately reach the preset position to meet the needs of the cleaning device for cleaning the corresponding part of the rotor. On the other hand, if abnormal conditions such as wear of the lead screw threads or loosening of the threaded connection of the sliding seat occur during transmission of the lead screw, the limiting rod can provide additional limiting protection to prevent the sliding seat from deviating from the normal movement track, thereby ensuring the safety and reliability of the entire device.

[0015] Further, the cleaning device comprises a second fixed seat, and the top end of the second fixed seat is fixedly connected with a second limiting seat through a second bolt.

[0016] By adopting the technical scheme, the second fixing base and the second limiting seat are firmly connected through the second bolt to form a relatively closed and stable space structure, which provides a stable mounting basis for the internally mounted spray gun, the bolt connection mode can ensure the integrity of the structure, facilitates the dismounting operation during installation and subsequent maintenance, and can ensure that the spray gun can be kept at an accurate position during the operation of the device to achieve effective cleaning of the steam turbine rotor.

[0017] Further, the second fixing base and the second limiting seat are internally mounted with the spray gun, one end of the spray gun is fixedly connected with the connecting pipe, and the other end of the spray gun is fixedly connected with the nozzle.

[0018] By adopting the technical scheme, one end of the spray gun is connected with the connecting pipe, the connecting pipe can transport external cleaning medium such as high-pressure gas and cleaning liquid to the inside of the spray gun, the connecting pipe plays the role of a medium transmission channel, and it is ensured that the cleaning medium can be continuously and stably supplied to the spray gun; when the cleaning medium enters the spray gun, under the action of the nozzle at one end of the spray gun, the cleaning medium is sprayed out of the outlet of the spray gun at a certain speed and pressure, so that it can accurately aim at the part of the steam turbine rotor that needs to be cleaned, such as oil stains, impurities and oxide skins that may exist on the surface of the rotor, and impact the target part through the high-speed sprayed cleaning medium, so as to remove various pollutants attached to the rotor and achieve the purpose of cleaning; if high-pressure gas is transported, the high-speed impact force of the gas can blow away loose impurities from the surface of the rotor; if cleaning liquid is transported, the cleaning liquid can not only remove part of the pollutants by means of the impact force of the liquid flow, but also remove some oil stains and other pollutants that are difficult to remove by pure impact through the action of dissolution and emulsification.

[0031] The driving gear 13 is also engaged with a second driven gear 14 fixed at one end of a lead screw 15, so that when the motor 12 rotates, the second driven gear 14 also rotates synchronously, and further drives the lead screw 15 to rotate, thereby ensuring the linkage of the whole tooling. The lead screw 15 is in threaded connection with a sliding seat 16, and when the lead screw 15 rotates under the driving of the second driven gear 14, the sliding seat 16 moves along the axial direction of the lead screw 15. This kind of lead screw transmission mode can realize accurate position control, so that the cleaning device 17 on the sliding seat 16 can accurately move to the part of the rotor 4 that needs to be cleaned. During the forging process of the rotor, some oxidation scales, impurities and the like need to be cleaned, and the cleaning device 17 can clean along the length direction of the rotor 4 through the movement of the sliding seat 16 on the lead screw 15.

[0032] As shown in Figure 1 , Figure 4 illustrated, the utility model still includes, the inside of the top end of first fixed seat 2 and the inside of the bottom end of first limit seat 3 are all provided with arc slot 18, and a plurality of connecting shafts are arranged in the inside of two arc slots 18, and a plurality of connecting shafts are all rotatably connected with gyro wheel 19 outside, the outside of gyro wheel 19 is attached with the outside of rotor 4.

[0033] In use, a plurality of gyro wheels 19 are installed in the arc slot 18 provided at the inside of the top end of the first fixed seat 2 and the inside of the bottom end of the first limit seat 3 through the connecting shafts, and when the rotor 4 is placed between the first fixed seat 2 and the first limit seat 3, the outside of the gyro wheels 19 is tightly attached with the outside of the rotor 4. During the rotation of the rotor 4, since the gyro wheels 19 are in rolling contact with the rotor 4 instead of sliding contact, according to the principle that the rolling friction coefficient is far less than the sliding friction coefficient, the friction force received by the rotor 4 during the rotation of the rotor 4 is greatly reduced. The rolling friction coefficient may be only about 0.01-0.05, while the sliding friction coefficient may reach 0.1-0.3. In this way, the rotor 4 can rotate more smoothly. The plurality of gyro wheels 19 are arranged in the arc slot 18 in a ring shape. This arrangement can enable the rotor 4 to receive uniform support force. In the entire circumferential direction of the rotor 4, each gyro wheel 19 collectively shares the weight of the rotor 4 and other forces generated during the rotation of the rotor 4, such as centrifugal force, thereby ensuring the stability of the rotor 4 during the rotation of the rotor 4 and preventing the rotor 4 from being deformed or deviated due to excessive local force.

[0034] As shown in Figure 1 , Figure 2 illustrated, the utility model still includes, the one side of lead screw 15 is provided with limit rod 20 in symmetry, the both ends of limit rod 20 are fixedly connected with the inside of two support seat 11, sliding seat 16 is connected with limit rod 20 in sliding.

[0035] In use, the sliding seat 16 is in sliding connection with the limiting rod 20 during the axial movement of the screw rod 15, which provides a clear movement direction for the sliding seat 16, ensuring that the sliding seat 16 can only move along the straight line defined by the limiting rod 20 without deviation, shaking or twisting; on the one hand, the limiting rod 20 limits the freedom of the sliding seat 16 in the direction perpendicular to the axial direction of the screw rod 15, preventing the sliding seat 16 from moving laterally due to uneven force during the movement driven by the rotation of the screw rod 15, ensuring the accuracy of the movement path of the sliding seat 16, so that it can accurately reach the preset position to meet the needs of the cleaning device 17 to clean the corresponding parts of the rotor 4; on the other hand, during the transmission of the screw rod 15, if abnormal conditions such as thread wear of the screw rod 15 or loosening of the threaded connection of the sliding seat 16 occur, the sliding seat 16 may move unstably, and the limiting rod 20 can provide additional limiting protection at this time to prevent the sliding seat 16 from deviating from the normal movement track, thereby ensuring the safety and reliability of the entire device.

[0036] As shown in Figure 1 , Figure 2 , the utility model also includes, the cleaning device 17 includes the second fixed seat 21, the second fixed seat 21 top end is fixedly connected with the second limiting seat 22 through the second bolt.

[0037] In use, the second fixed seat 21 and the second limiting seat 22 are firmly connected through the second bolt to form a relatively closed and stable space structure, providing a stable installation basis for the internally installed spray gun 23. This bolt connection method not only ensures the integrity of the structure, facilitating installation and subsequent disassembly operations during maintenance, but also ensures that the spray gun 23 can remain in the correct position during device operation to achieve effective cleaning of the steam turbine rotor.

[0038] As shown in Figure 1 , Figure 2 , the utility model also includes, the second fixed seat 21 and the second limiting seat 22 are firmly connected through the second bolt to form a relatively closed and stable space structure, providing a stable installation basis for the internally installed spray gun 23. This bolt connection method not only ensures the integrity of the structure, facilitating installation and subsequent disassembly operations during maintenance, but also ensures that the spray gun 23 can remain in the correct position during device operation to achieve effective cleaning of the steam turbine rotor.

[0039] During use, one end of the spray gun 23 is connected to a connecting pipe 24. External cleaning media, such as high-pressure gas or cleaning fluid, can be delivered to the spray gun 23 through the connecting pipe 24. The connecting pipe 24 acts as a media transmission channel, ensuring a continuous and stable supply of cleaning media to the spray gun 23. Once the cleaning media enters the spray gun 23, it is propelled out of the outlet at a certain speed and pressure by the nozzle at one end of the spray gun 23. This allows it to accurately target the parts of the turbine rotor that need cleaning, such as oil stains, impurities, and scale that may be present on the rotor surface. The high-speed spray of the cleaning media impacts the target area, thereby removing various contaminants adhering to the rotor and achieving the cleaning purpose. If high-pressure gas is being transported, the high-speed impact force of the gas can blow loose impurities away from the rotor surface. If cleaning fluid is being transported, after being sprayed onto the rotor surface, the fluid can both carry away some contaminants with the impact force of the liquid flow and remove some oil stains and other contaminants that are difficult to remove by simple impact through dissolution and emulsification.

[0040] It should be noted that this utility model is a tooling for a turbine rotor forging. First, the rotor 4 is placed between the first fixed seat 2 and the first limiting seat 3. At this time, the outer side of the rotor 4 is closely fitted with the roller 19 in the arc groove 18 on the inner side of the top of the first fixed seat 2 and the inner side of the bottom of the first limiting seat 3. The roller 19 plays the role of support and reducing friction. Turn the handle 9 to rotate the threaded rod 7. Due to the threaded connection between the threaded rod 7 and the two clamping plates 8 and the sliding cooperation between the clamping plates 8 and the fixed frame 6, the two clamping plates 8 will move relative to each other and approach the rotor 4. Continue to turn the handle 9 until the clamping plates 8 clamp the rotor 4. At this time, the rotor 4 is connected to the rotating device 5 as one unit and can rotate under the drive of the motor 12.

[0041] When the motor 12 is started, the drive gear 13 at the output end of the motor 12 begins to rotate. The drive gear 13 drives the first driven gear 10 meshing with it to rotate, thereby causing the entire rotating device 5, together with the clamped rotor 4, to rotate inside the first limiting seat 3 and the first fixed seat 2. Rotor processing or inspection operations can be performed. At the same time, the drive gear 13 drives the second driven gear 14 to rotate, thereby causing the lead screw 15 fixedly connected to the second driven gear 14 to rotate.

[0042] When the lead screw 15 rotates, the slide 16 threaded onto it will move along the axial direction of the lead screw 15. During the movement, the slide 16 is guided and limited by the limiting rod 20, and can only move in a straight line to ensure accurate movement path. As the slide 16 moves, the cleaning device 17 installed on it moves accordingly. The connecting pipe 24 in the cleaning device 17 delivers external cleaning medium, such as high-pressure gas or cleaning liquid, to the spray gun 23. The cleaning medium is sprayed out at a certain speed and pressure under the action of the nozzle of the spray gun 23, impacting the oil, impurities, oxide scale and other contaminants on the surface of the rotor 4, thereby cleaning the rotor 4.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
