Description

Technical Field

[0001] This utility model relates to the field of manufacturing equipment, specifically a rapid manufacturing equipment for a steam turbine rotor assembly bracket. Background Technology

[0002] The rapid manufacturing equipment for turbine rotor assembly brackets is a type of equipment used in the field of turbine manufacturing, specifically designed for the rapid and efficient production of rotor assembly brackets. As a key piece of equipment in industries such as power and energy, the quality and manufacturing efficiency of the rotor assembly brackets directly affect the overall performance and production cycle of the turbine. With the continuous growth of electricity demand and the rapid development of the energy industry, the requirements for the quantity and quality of turbine production are increasing. In order to meet the needs of large-scale, high-quality production, equipment capable of rapidly manufacturing high-precision, reliable turbine rotor assembly brackets is particularly important. It can not only shorten the turbine production cycle and reduce production costs, but also improve the stability and reliability of the entire energy production system.

[0003] In traditional turbine rotor assembly bracket manufacturing technology, the material feeding process largely relies on manual operation. Personnel place the materials to be processed into the processing position, which is inefficient, time-consuming, and slows down the overall manufacturing progress. Furthermore, manual operation makes it difficult to guarantee the accuracy and stability of the material feeding, as deviations can easily occur during placement, affecting subsequent processing precision. Regarding centering and clamping, traditional technologies often use simple clamping devices that are difficult to achieve precise automatic centering and clamping of the workpiece. The workpiece is prone to shifting and wobbling during clamping, and designs such as rollers to reduce friction and stabilize the workpiece are often lacking. This makes it difficult to ensure the precise position of the workpiece during assembly, affecting the manufacturing precision of the assembly bracket and consequently reducing the overall performance of the turbine rotor. Therefore, we propose a rapid manufacturing equipment for turbine rotor assembly brackets. Summary of the Invention

[0028] Structural Description:

[0029] Feeding base 1: Feeding base 1 is the basic support structure of the entire feeding process of the equipment. Support legs are installed at the four corners of its bottom surface to maintain stability. It provides installation positions for other components of the feeding mechanism. It is set adjacent to clamping base 10 and together they form the working plane of the equipment. During the operation of the equipment, it plays the role of bearing the materials to be processed and related feeding components.

[0030] Hydraulic cylinder 2: Hydraulic cylinder 2 is fixedly installed on one side of the upper surface of the feeding base 1. It provides power through the extension and retraction of the piston rod. It is connected to the push plate 3 and drives the push plate 3 to slide inside the support plate 6, thereby pushing the material placed in the feeding port of the support plate 6 to the designated position. It is the core power source for the automated operation of the feeding mechanism.

[0031] Push plate 3: Push plate 3 is fixedly connected to the piston rod of hydraulic cylinder 2 and is engaged and slidable with the discharge port of support plate 6. Its surface is provided with a placement groove corresponding to the inlet of support plate 6 for receiving materials. Springs 5 ​​are symmetrically installed in the placement groove to buffer and push the materials, playing a role in accurately pushing and protecting the materials during the feeding process.

[0032] Limiting post 4: The limiting post 4 is fixed on the upper surface of the support plate 6 at the four corners corresponding to the discharge port. Its main function is to limit the movement range of the material, ensure that the material maintains the correct position and direction when it is fed, prevent the material from deviating during the falling process, and ensure the stability and accuracy of the feeding process.

[0033] Spring 5: Spring 5 is symmetrically installed in the placement slot of push plate 3. When the material is fed, the spring can buffer the collision between the material and the push plate to avoid damage to the material. At the same time, when push plate 3 is pushed out, spring 5 releases its elastic force to eject the material from the placement slot, so that the material can smoothly leave push plate 3 and enter the subsequent processing stage, improving feeding efficiency and automation.

[0034] Support plate 6: Support plate 6 is installed on the other side of the upper surface of the feeding base 1. Its surface is provided with a feeding port and its side wall has a through discharge port. It provides an initial placement position for the material and works with push plate 3 to realize the material conveying. Limiting post 4 is installed at the four corners of its discharge port. It is an important guiding and supporting structure for the material conveying path in the feeding mechanism.

[0035] Roller 7: Roller 7 is mounted on two shafts of roller bracket 8. Roller bracket 8 is rotatably connected to the rotating column on sliding plate 12. When the centering clamping mechanism is working, roller 7 contacts the object to be clamped, which can reduce friction during the clamping process, assist the object in centering, ensure that the object remains stable during clamping and assembly, and reduce wear.

[0036] Roller bracket 8: The roller bracket 8 is L-shaped. One end is rotatably connected to the rotating column protruding from the plane of the clamping top plate 9 on the sliding plate 12, and the other end is equipped with roller 7. It connects roller 7 to the sliding plate 12, so that roller 7 can play a role in the clamping process. It is a key connecting component in the centering clamping mechanism to reduce friction and stabilize objects.

[0037] Clamping top plate 9: The clamping top plate 9 is fixed to the four corners of the upper surface of the clamping base 10 by the support column. It has a sliding groove tangent to the rotating column of the sliding plate 12. It and the clamping base 10 together form a clamping space. The sliding groove restricts the movement of the rotating column, ensuring the movement accuracy of the sliding plate 12 during the clamping process and ensuring the clamping effect.

[0038] Clamping base 10: Support legs are installed at the four corners of the bottom surface of clamping base 10 to ensure the stability of the equipment. Support columns are installed on the upper surface to fix the clamping top plate 9. At the same time, it provides installation positions for components such as sliding seat 11, motor 15, and hydraulic cylinder 16 of the centering clamping mechanism. It is the basic support structure of the centering clamping mechanism and bears the relevant components of the clamping operation.

[0039] Sliding seat 11: The sliding seat 11 is symmetrically fixed on the upper surface of the clamping base 10. It has sliding grooves on both sides. It cooperates with the slider of the sliding plate 12 to provide a sliding track for the sliding plate 12, so that the sliding plate 12 can move smoothly on the clamping base 10, ensuring the movement accuracy and stability of the sliding plate 12 when the centering clamping mechanism is working.

[0040] Sliding plate 12: The bottom surface of the sliding plate 12 is equipped with a slider that slides in the groove of the sliding seat 11. The upper surface is provided with a rotating connecting block and a rotating column. It moves under the action of connecting rod 13, connecting rod 24 and hydraulic cylinder 26 to achieve the clamping action of the object. It is the key component in the centering clamping mechanism that directly contacts the object and performs the clamping operation.

[0041] Link 13: One end of link 13 is rotatably connected to link 214, and the other end is rotatably connected to the rotating connecting block on the sliding plate 12. When the motor 15 drives link 214 to rotate, link 13 converts the rotation of link 214 into the linear motion of the sliding plate 12, so that the two sliding plates 12 move closer or further apart synchronously, thereby realizing the centering and clamping operation of the object.

[0042] Link 2 14: Link 2 14 is rotatably connected to the connecting hole of the clamping base 10 on the same axis. Both ends are rotatably connected to Link 1 13 respectively. It rotates under the drive of the motor 15. As the core component for motion transmission of the centering clamping mechanism, it drives the sliding plate 12 to move through cooperation with Link 1 13, so as to realize the clamping control of the object.

[0043] Motor 15: Motor 15 is fixedly installed in the middle of the bottom surface of clamping base 10. The output shaft is fixedly connected to connecting rod 2 14. It provides power for the centering clamping mechanism. By driving connecting rod 2 14 to rotate, it drives connecting rod 1 13 and sliding plate 12 to move, realizing automatic centering and clamping of the object. It is the power source for the centering clamping action.

[0044] Hydraulic cylinder 2 16: Hydraulic cylinder 2 16 is installed next to the connecting hole on the upper surface of the clamping base 10. The piston rod is fixed to the side of one of the sliding plates 12. It can make fine adjustments to the sliding plate 12, assist the motor 15 and the linkage mechanism to achieve more precise clamping operation, improve the accuracy of centering clamping, and ensure the position accuracy of the object during the clamping process.

[0045] Working principle: First, the material to be processed is placed in the inlet of the support plate 6. After the equipment is started, the hydraulic cylinder 2 begins to work, and its piston rod extends to push the push plate 3, which is fixedly connected to it. Since the push plate 3 is engaged and slidably connected to the outlet of the support plate 6, the push plate 3 will slide along the outlet. During this process, the placement groove on the push plate 3, which corresponds to the inlet of the support plate 6, accurately receives the material. The springs 5, which are symmetrically installed in the placement groove, play a buffering role to prevent the material from being damaged by collision during the pushing process. At the same time, they can also finely adjust the positioning of the material. When the push plate 3 moves to the designated position, the spring 5 releases its elastic force to eject the material from the placement groove, allowing the material to enter the subsequent processing stage. The limiting post 4 is fixed at the four corners of the outlet of the support plate 6 to limit the movement range of the material and ensure that the material maintains the correct position and direction when feeding, ensuring the stability and accuracy of the feeding process. Through this series of linkages, the feeding mechanism realizes automated feeding, which greatly improves the feeding efficiency, accuracy and stability compared with traditional manual feeding, and reduces labor costs.

[0046] Motor 15 is fixed at the center of the bottom surface of clamping base 10. When motor 15 is started, its output shaft drives the connecting rod 14, which is fixedly connected to it, to rotate. Connecting rod 14 is coaxially rotatably connected in the connecting hole of clamping base 10, and its two ends are rotatably connected to connecting rod 13. When connecting rod 14 rotates, it drives connecting rod 13 to move. The other end of connecting rod 13 is rotatably connected to the rotating connecting block on sliding plate 12, thereby converting the rotation of connecting rod 14 into the linear motion of sliding plate 12. The slider on the bottom surface of sliding plate 12 engages and slides with the groove of sliding seat 11. Sliding seat 11 is symmetrically fixed on the upper surface of clamping base 10, providing a sliding track for sliding plate 12 to ensure the accuracy and stability of sliding plate 12's movement. Rotating columns are fixedly installed diagonally symmetrically on the upper surfaces of the two sliding plates 12. A through sliding groove is opened on the clamping top plate 9 corresponding to the rotating column, and the sliding... The moving groove is tangential to and slidably connected to the rotating column, further restricting the movement trajectory of the sliding plate 12. In addition, the hydraulic cylinder 16 is installed next to the connecting hole on the upper surface of the clamping base 10, and its piston rod is fixed to the side of one of the sliding plates 12, which can make fine adjustments to the sliding plate 12. The auxiliary motor 15 and the linkage mechanism realize more precise clamping operation. During the movement of the sliding plate 12, the roller bracket 8 and roller 7 installed on its rotating column move accordingly. The roller bracket 8 is L-shaped, and the roller 7 is installed on its two shafts. The roller 7 contacts the object to be clamped, reducing friction during the clamping process, assisting in centering the object, and ensuring that the object remains stable during clamping and assembly. Through the coordinated linkage of these components, the centering clamping mechanism realizes automatic centering and clamping of the object, ensuring the accuracy of the object position during processing and improving the manufacturing accuracy of the assembly bracket.
