Description

Technical Field

[0001] The utility model relates to the field of production and processing of steam turbine blades, in particular to an adjustable positioning device for production and processing of steam turbine blades. Background Art

[0002] Steam turbine blades are extremely important components in steam turbines. During the operation of steam turbines, high-temperature and high-pressure steam impacts the blades, causing the blades to drive the rotor to rotate, converting the thermal energy and kinetic energy of the steam into mechanical energy, thereby driving the generator to generate electricity or driving other mechanical equipment to operate. Steam turbine blades are generally composed of three parts: blade root, blade body and blade tip. The blade root is the part where the blade is connected to the steam turbine rotor. Its function is to firmly fix the blade on the rotor to withstand the force of steam. The blade body is the main part of the blade. Its shape and size directly affect the efficiency and performance of the steam turbine. The blade body is usually twisted to adapt to the speed change of steam at different radii. There are also various structural forms of the blade tip, such as shrouds, tie rods, etc. The shrouds can increase the rigidity of the blades and reduce the vibration of the blades; tie rods can play a role in strengthening the strength of the blades. When processing steam turbine blades, the position of the turbine blades needs to be positioned to prevent the turbine blades from offsetting and affecting the processing accuracy during the processing.

[0003] China's published patent application number: CN202321313472.3, provides an adjustable positioning device for the production and processing of turbine blades. This solution fixes the turbine blades by setting a distance adjustment mechanism, an adjustment component, a stabilization component, and a fixing component. However, when processing the turbine blades, it is necessary to repeatedly pick up the turbine blades. The positioning device mentioned in the above patent mainly sets a fixing ring and a fixing plate. When in use, the fixing ring and the fixing plate can fix the turbine blades. When taking the turbine blades, the fixing ring and the fixing plate need to be separated first, and the size and shape of the fixing ring are fixed, which is not convenient to adjust according to the size of the turbine blades, and is not convenient to use.

[0004] To this end, we propose an adjustable positioning device for the production and processing of turbine blades. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of the present invention is to provide an adjustable positioning device for the production and processing of turbine blades, which uses anti-slip support plates to abut and fix the inner ring of the turbine blade body, making it convenient for users to process the turbine blade body, and the opening and closing degree of the anti-slip support plates can be adjusted according to the turbine blade bodies with different inner diameters, so as to facilitate the positioning of turbine blade bodies of different specifications.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] An adjustable positioning device for the production and processing of steam turbine blades includes an adjusting component, the top of which is equipped with a steam turbine blade body; the adjusting component includes an outer shell, a positioning ring is installed inside the outer shell, a plug-in column is provided inside the positioning ring, the bottom end of the plug-in column passes through the positioning ring and is fixedly connected to the bottom end of the inner shell, the top end of the plug-in column passes through the top end of the outer shell, the top end of the positioning ring is slidably connected to a plurality of sliders arranged at equal intervals, the top end of the slider is fixedly connected to an anti-slip support plate, the anti-slip support plate passes through the top end of the outer shell, and the anti-slip support plate is adapted to the plug-in column.

[0008] The positioning ring plays a supporting and guiding role, the slider slides on the top of the positioning ring, and the anti-slip support piece on the top of the slider moves accordingly. The anti-slip support piece runs through the top of the shell and is adapted to the plug-in column. When the slider slides, it will drive the anti-slip support piece to move. By changing the position of the slider, the opening and closing degree of the anti-slip support piece can be adjusted. When the anti-slip support pieces move outward and open, they will tightly abut against the inner ring of the turbine blade body, thereby fixing the turbine blade body and facilitating processing operations for users.

[0009] Furthermore, a motor is fixedly connected to the bottom of the housing, and a worm is fixedly connected to the output end of the motor;

[0010] The motor serves as the power source for the entire device and is fixed to the bottom of the housing. When the motor starts, its output end drives the worm to rotate, and the rotation of the worm provides power for subsequent component movement. By precisely controlling the rotation direction and speed of the motor, precise adjustment of the entire positioning device can be achieved.

[0011] Furthermore, a plurality of connecting rods arranged at equal intervals are fixedly connected to the middle of the positioning ring, and the connecting rods are fixedly connected to the inner wall of the shell;

[0012] The connecting rods are evenly distributed in the middle of the positioning ring and fixedly connected to the inner wall of the shell. This design enables the positioning ring to be stably installed inside the shell. The connecting rods support and fix the positioning ring, ensuring that the positioning ring will not shake or shift during operation, thereby ensuring the movement accuracy of the slider and the anti-slip support piece, and providing a basis for accurately positioning the turbine blade body.

[0013] Furthermore, the bottom end of the positioning ring is rotatably connected to a connecting ring, the connecting ring is sleeved on the outside of the plug-in column, the middle of the connecting ring is fixedly connected to a bottom ring, the bottom ring is located below the positioning ring, and the bottom ring is adapted to the positioning ring;

[0014] The connecting ring at the bottom end of the positioning ring can rotate freely around the plug-in column. The bottom ring in the middle of the connecting ring is adapted to the positioning ring. The bottom ring establishes a connection relationship with the positioning ring through the connecting ring. When the bottom ring rotates due to external force, it will drive other components on the positioning ring to move together through the connecting ring. This rotating connection design provides key structural support for realizing the opening and closing action of the anti-slip support plate.

[0015] Furthermore, the bottom end of the positioning ring is slidably connected to a plurality of guide posts, and the top ends of the guide posts pass through the bottom end of the positioning ring and are fixedly connected to the slider.

[0016] Furthermore, the top end of the guide column passes through the bottom ring, and the guide column is slidably connected to the bottom ring.

[0017] Furthermore, a worm gear is fixedly connected to the bottom end of the bottom ring, the worm gear is engaged with the worm, and the worm gear is sleeved on the outside of the plug-in column.

[0018] Furthermore, an arc-shaped opening adapted for the guide post is formed at the top end of the bottom ring, and the arc-shaped opening is slidably connected to the guide post.

[0021] 2. The positioning ring and the bottom ring cooperate to facilitate the guide column to drive the slider to open or close. At the same time, the slider drives the anti-slip support piece to open and close, thereby abutting and fixing the inner ring of the turbine blade body to position the turbine blade body.

DETAILED DESCRIPTION

[0029] The present invention will be described in further detail below with reference to the accompanying drawings.

[0030] Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0031] Reference Figures 1-6 As shown, an adjustable positioning device for the production and processing of turbine blades in a preferred embodiment of the present invention includes an adjusting component 1, and a turbine blade body 2 is installed on the top of the adjusting component 1; the adjusting component 1 includes an outer shell 101, and a positioning ring 102 is installed inside the outer shell 101, and a plug-in column 109 is provided inside the positioning ring 102. The bottom end of the plug-in column 109 passes through the positioning ring 102 and is fixedly connected to the bottom end of the inner shell 101, and the top end of the plug-in column 109 passes through the top of the outer shell 101. The top end of the positioning ring 102 is slidably connected to a plurality of sliders 110 arranged at equal intervals, and the top end of the slider 110 is fixedly connected to an anti-slip support sheet 111, which passes through the top of the outer shell 101 and is adapted to the plug-in column 109.

[0032] The positioning ring 102 plays a supporting and guiding role, and the slider 110 slides on the top of the positioning ring 102, and the anti-slip support piece 111 on the top of the slider 110 moves accordingly. The anti-slip support piece 111 passes through the top of the shell 101 and is adapted to the plug-in column 109. When the slider 110 slides, it will drive the anti-slip support piece 111 to move. By changing the position of the slider 110, the opening and closing degree of the anti-slip support piece 111 can be adjusted. When the anti-slip support piece 111 moves outward and opens, they will tightly abut against the inner ring of the turbine blade body 2, thereby fixing the turbine blade body 2 and facilitating the user's processing operations.

[0033] The bottom of the housing 101 is fixedly connected to a motor 108, and the output end of the motor 108 is fixedly connected to a worm 107;

[0034] The motor 108 serves as the power source for the entire device and is fixed to the bottom of the housing 101. When the motor 108 is started, its output end will drive the worm 107 to rotate. The rotation of the worm 107 will provide power for subsequent component movements. By precisely controlling the rotation direction and speed of the motor 108, precise adjustment of the entire positioning device can be achieved.

[0035] A plurality of equally spaced connecting rods 103 are fixedly connected to the middle of the positioning ring 102, and the connecting rods 103 are fixedly connected to the inner wall of the housing 101;

[0036] The connecting rods 103 are evenly distributed in the middle of the positioning ring 102 and fixedly connected to the inner wall of the shell 101. This design enables the positioning ring 102 to be stably installed inside the shell 101. The connecting rods 103 support and fix the positioning ring 102, ensuring that the positioning ring 102 does not shake or shift during operation, thereby ensuring the movement accuracy of the slider 110 and the anti-slip support plate 111, and providing a basis for accurately positioning the turbine blade body 2.

[0037] The bottom end of the positioning ring 102 is rotatably connected to a connecting ring 105, which is sleeved on the outside of the plug-in column 109. The middle of the connecting ring 105 is fixedly connected to a bottom ring 104, which is located below the positioning ring 102 and is adapted to the positioning ring 102.

[0038] The connecting ring 105 at the bottom end of the positioning ring 102 can rotate freely around the plug-in column 109, and the bottom ring 104 in the middle of the connecting ring 105 is adapted to the positioning ring 102. The bottom ring 104 establishes a connection relationship with the positioning ring 102 through the connecting ring 105. When the bottom ring 104 is rotated by external force, it will drive other components on the positioning ring 102 to move together through the connecting ring 105. This rotating connection design provides key structural support for realizing the opening and closing action of the anti-slip support plate 111.

[0039] The bottom end of the positioning ring 102 is slidably connected to a plurality of guide posts 112 , and the top ends of the guide posts 112 pass through the bottom end of the positioning ring 102 and are fixedly connected to the slider 110 ;

[0040] The guide column 112 is slidably connected to the bottom end of the positioning ring 102, and its top end is fixedly connected to the slider 110. When an external force acts on the guide column 112, the guide column 112 will move along the sliding track at the bottom end of the positioning ring 102, thereby driving the slider 110 to slide on the top end of the positioning ring 102. This design ensures that the slider 110 can move in a predetermined direction and trajectory, thereby realizing the accurate opening and closing of the anti-slip support piece 111 to adapt to turbine blade bodies 2 with different inner diameters.

[0041] The top end of the guide post 112 passes through the bottom ring 104 , and the guide post 112 is slidably connected to the bottom ring 104 ;

[0042] The guide column 112 is not only slidably connected to the positioning ring 102, but also passes through the bottom ring 104 and is slidably connected to the bottom ring 104. The structure on the bottom ring 104 cooperates with the guide column 112. When the bottom ring 104 rotates, the specific structure on the bottom ring 104 will push the guide column 112 to move. Since the guide column 112 is fixedly connected to the slider 110, the rotation of the bottom ring 104 will be transmitted to the slider 110 through the guide column 112, causing the slider 110 to slide on the positioning ring 102, and finally realizing the opening and closing action of the anti-slip support piece 111.

[0043] The bottom end of the bottom ring 104 is fixedly connected to a worm gear 106 , which is engaged with a worm 107 . The worm gear 106 is sleeved on the outside of the plug-in column 109 .

[0044] The worm wheel 106 at the bottom end of the bottom ring 104 is meshed with the worm 107. When the worm 107 rotates under the drive of the motor 108, the worm wheel 106 will rotate under the action of the worm 107. Since the worm wheel 106 is mounted on the outside of the plug-in column 109 and is fixedly connected to the bottom ring 104, the rotation of the worm wheel 106 will drive the bottom ring 104 to rotate together. This transmission structure of the worm wheel 106 and worm 107 has the characteristics of smooth transmission and high precision, and can accurately control the rotation angle and speed of the bottom ring 104, thereby realizing precise adjustment of the opening and closing degree of the anti-slip support plate 111.

[0045] The top of the bottom ring 104 is provided with an arc-shaped opening adapted to fit the guide post 112, and the arc-shaped opening is slidably connected to the guide post 112;

[0046] The arc-shaped opening at the top of the bottom ring 104 is slidably connected to the guide column 112. When the bottom ring 104 rotates, the arc-shaped opening will slide along the guide column 112, and due to the shape and position of the arc-shaped opening, the arc-shaped opening will generate a thrust or pull on the guide column 112, causing the guide column 112 to slide between the positioning ring 102 and the bottom ring 104. The sliding of the guide column 112 will drive the slider 110 to slide at the top of the positioning ring 102, thereby changing the position and opening and closing degree of the anti-slip support piece 111. Through this ingenious design, the rotation of the bottom ring 104 can be converted into the opening and closing action of the anti-slip support piece 111, thereby realizing the positioning of turbine blade bodies 2 of different specifications.

[0047] Specific implementation process: First, place the turbine blade body 2 above the adjusting assembly 1, start the motor 108, and the motor 108 drives the worm 107 to rotate. Since the worm 107 is engaged with the worm gear 106, the worm gear 106 will rotate under the drive of the worm 107. The worm gear 106 is fixed to the bottom end of the bottom ring 104, and the bottom ring 104 is rotatably connected to the positioning ring 102 through the connecting ring 105, and the arc-shaped opening at the top of the bottom ring 104 is slidingly connected to the guide post 112. When the worm gear 106 rotates, it will drive the bottom ring 104 to rotate, and the arc-shaped opening on the bottom ring 104 will push the guide post 112 to move. Because the guide post 112 is fixedly connected to the slider 110, and the slider 110 is slidingly connected to the top of the positioning ring 102, the guide post 112 will drive the slider 110 to slide on the positioning ring 102. Multiple sliders 110 are arranged at equal distances. When the slider 110 slides, it will drive the anti-slip support plate. 111 moves, and the anti-slip support piece 111 passes through the top of the shell 101. The opening or closing action of the slider 110 will change the opening and closing degree of the anti-slip support piece 111. When the anti-slip support piece 111 moves outward and opens, it will abut and fix the inner ring of the turbine blade body 2. Since the movement of the slider 110 can be controlled by the motor 108, the opening and closing degree of the anti-slip support piece 111 can be adjusted according to the turbine blade body 2 with different inner diameters, so as to achieve the positioning of the turbine blade body 2 of different specifications, which is convenient for the user to process the turbine blade body 2. After the processing is completed, the motor 108 is started in reverse to retract the anti-slip support piece 111, and the turbine blade body 2 can be easily removed, which is convenient for the user to repeatedly take out the turbine blade body 2. It can also be adjusted according to the turbine blade body 2 of different sizes to adapt to the turbine blade body 2 of more specifications, making it more convenient to use.
