The thickness and fit precision of the contact surface between the steam seal ring and the inner ring groove of the steam seal groove directly determine the radial position of the assembled steam seal ring, thus precisely controlling the size of the steam seal gap. An excessively large steam seal gap can easily lead to leakage and reduced efficiency, while an excessively small gap can easily cause rubbing failure.

[0020] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] See also Figures 1 to 7 As shown, according to an embodiment of this application, a sealing component grinding device 300 is provided for grinding the contact surface 101 of a steam seal ring, which is spliced ​​from multiple steam seal ring arc segments 100, and which mates with the inner ring groove 200 of the steam seal groove. The device includes a frame 301, an operating platform 302, and a grinding mechanism 304. The operating platform 302 is mounted on the frame 301 and has multiple position-adjustable rotating support columns 303 arranged in an arc shape. The extension direction is consistent with the manual pushing direction of the steam seal ring arc segment 100. The rotating support column 303 is used to fit with the back arc surface 102 of the steam seal ring arc segment 100 and can rotate as the steam seal ring arc segment 100 is manually pushed from one side to the other along the operating platform 302. The grinding mechanism 304 is set on the frame 301 and is used to grind the contact surface 101 during the manual pushing of the steam seal ring arc segment 100 from one side to the other along the operating platform 302.

[0022] The sealing component grinding device 300 provided in this embodiment of the application uses multiple position-adjustable rotating support columns 303 set on the operating platform 302 of the frame 301. The rotating support columns 303 are in contact with the back arc surface 102 of the steam seal ring arc segment 100 and are arranged in an arc shape along the manual pushing direction of the steam seal ring arc segment 100. During the manual pushing process of the steam seal ring arc segment 100 from one side to the other, the rotating support columns 303 rotate synchronously with the steam seal ring arc segment 100. In conjunction with the grinding mechanism 304 set on the frame 301, the contact surface 101 of the steam seal ring arc segment 100 and the inner ring groove 200 of the steam seal groove can be stably ground during the pushing process. This achieves convenient positioning and reliable support for the steam seal ring arc segment 100, simplifies the clamping process, improves grinding accuracy and processing efficiency, and accurately controls the thickness and fit accuracy of the contact surface 101. This ensures the stability and reliability of the steam seal gap and reduces the risk of air leakage and grinding failure.

[0023] It is understood that the sealing component grinding device 300 includes a frame 301, an operating platform 302, and a grinding mechanism 304. The frame 301 serves as the overall support foundation, providing a stable mounting base for the operating platform 302 and the grinding mechanism 304. The operating platform 302 is movably mounted on the frame 301 and is used to adjust the radial machining amount of the steam seal ring arc segment 100 to adapt to actual machining requirements. Multiple position-adjustable rotating support columns 303 are arranged on the operating platform 302. The multiple rotating support columns 303 are arranged in an arc-shaped extension direction, which is adapted to the arc-shaped manual pushing direction of the steam seal ring arc segment 100, ensuring that when the steam seal ring arc segment 100 is pushed along its own arc trajectory, the back arc surface 102 is always stably in contact with each rotating support column 303. The rotating support column 303 is used to fit against the back arc surface 102 of the steam seal ring arc segment 100, and can rotate along with the steam seal ring arc segment 100 as it is manually pushed from one side to the other along the operating platform 302. The direction of the operating platform 302 from one side to the other is the arc-shaped arrangement direction of the multiple rotating support columns 303. This ensures that the back arc surface 102 of the steam seal ring arc segment 100 is always in contact with the rotating support column 303 during the pushing process, and each rotating support column 303 can rotate smoothly with the pushing action, avoiding pushing jamming and support offset, and ensuring the stability and processing accuracy of the grinding process. The grinding mechanism 304 is vertically mounted on the frame 301 and is used to adjust the axial machining amount of the contact surface 101 of the steam seal ring arc segment 100 to precisely control the grinding thickness of the contact surface 101. The grinding mechanism 304 includes a motor base, a motor, and an electric grinding head. The motor base is vertically mounted on the frame 301, the motor is fixedly mounted on the motor base, and the electric grinding head is connected to the output end of the motor. The grinding mechanism 304 and the operating platform 302 form a corresponding cooperation relationship, and the machining position of the electric grinding head is facing the contact surface 101 of the steam seal ring arc segment 100 that mates with the inner ring groove 200 of the steam seal groove.

[0024] Understandably, when the sealing component grinding device 300 is working, it places each of the steam seal ring arc segments 100, which are spliced ​​together from multiple steam seal ring arc segments 100, onto the operating platform 302 one by one, so that the back arc surface 102 of each steam seal ring arc segment 100 is stably in contact with multiple rotating support columns 303. The operator manually pushes a single steam seal ring arc segment 100 from one side to the other along the operating platform 302. The rotating support columns 303 rotate synchronously with the pushing action to reduce motion resistance and maintain stable support. During the manual pushing of the sealing ring arc segment 100, the grinding mechanism 304 on the frame 301 continuously grinds the contact surface 101 of the steam seal arc segment 100 that mates with the inner ring groove 200 of the steam seal groove. After the contact surface 101 of each steam seal arc segment 100 is ground, the steam seal arc segment 100 is flipped over and its other side contact surface 101 is ground until all the contact surface 101 of the steam seal arc segments 100 are ground, thereby achieving precise machining of the contact surface 101 of each steam seal arc segment 100.

[0025] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figures 2 to 5 As shown, the frame 301 includes a horizontally arranged support base 3011 and a vertically fixed support plate 3012 fixed to the support base 3011; a horizontal adjustment mechanism 305 is provided on the support base 3011, and an operating platform 302 is connected to the horizontal adjustment mechanism 305. The operating platform 302 is movable along the length direction of the support base 3011 through the horizontal adjustment mechanism 305; a vertical adjustment mechanism 306 is provided on the support plate 3012, and a grinding mechanism 304 is connected to the vertical adjustment mechanism 306. The grinding mechanism 304 is raised and lowered along the height direction of the support plate 3012 through the vertical adjustment mechanism 306.

[0026] In this embodiment, the frame 301 provides a stable mounting carrier for the horizontal adjustment mechanism 305 and the vertical adjustment mechanism 306 by setting a horizontally arranged support base 3011 and a vertically fixed support plate 3012 on the support base 3011. The horizontal adjustment mechanism 305 on the support base 3011 is connected to the operating platform 302, so that the operating platform 302 can be moved along the length direction of the support base 3011, thereby allowing precise adjustment of the position of the operating platform 302 to adapt to the radial machining requirements of the gas seal ring arc segment 100. The vertical adjustment mechanism 306 on the support plate 3012 is connected to the grinding mechanism 304, so that... The grinding mechanism 304 can be raised and lowered along the height direction of the support plate 3012, thereby allowing precise adjustment of the height of the grinding mechanism 304 to meet the axial machining requirements of the contact surface 101 of the steam seal ring arc segment 100. The two work together to achieve precise adjustment of the operating platform 302 and the grinding mechanism 304, further improving the grinding accuracy of the contact surface 101 of the steam seal ring arc segment 100, adapting to the grinding requirements under different processing scenarios, while ensuring the stability of the entire device structure and the convenience of adjustment, indirectly improving processing efficiency, ensuring that the thickness and fitting accuracy of the contact surface 101 after grinding meet the requirements, and thus ensuring the stability and reliability of the steam seal gap.

[0027] It is understood that the frame 301 of the sealing component grinding device 300 includes a horizontally arranged support seat 3011 and a vertically fixed support plate 3012. The frame 301, by setting the support seat 3011 and the support plate 3012, provides a stable mounting carrier for the horizontal adjustment mechanism 305 and the vertical adjustment mechanism 306. The support seat 3011 is arranged horizontally, and its length direction corresponds to the width direction of the operating platform 302. The horizontal adjustment mechanism 305 is fixedly installed on the support seat 3011. The operating platform 302 is fixedly connected to the horizontal adjustment mechanism 305. The operating platform 302 can be moved along the length direction of the support seat 3011 through the horizontal adjustment mechanism 305, thereby allowing precise adjustment of the position of the operating platform 302 to adapt to the radial machining requirements of the gas seal ring arc segment 100. The support plate 3012 is vertically fixed on the bearing seat 3011, forming a stable support structure. A vertical adjustment mechanism 306 is fixedly installed on the support plate 3012. The grinding mechanism 304 is fixedly connected to the vertical adjustment mechanism 306. The grinding mechanism 304 can be raised and lowered along the height direction of the support plate 3012 through the vertical adjustment mechanism 306, so that the height of the grinding mechanism 304 can be precisely adjusted to adapt to the axial machining requirements of the contact surface 101 of the steam seal ring arc segment 100. Multiple rotating support columns 303 on the operating platform 302 are arranged in an arc shape along the length direction of the operating platform 302, which is adapted to the arc-shaped manual pushing direction of the steam seal ring arc segment 100.

[0028] It is understandable that when the horizontal adjustment mechanism 305 is working, it can drive the operating platform 302 connected to it to move along the length direction of the support seat 3011. Since the length direction of the support seat 3011 is the width direction of the operating platform 302, the movement of the operating platform 302 can accurately adjust the radial machining position of the steam seal ring arc segment 100 to adapt to the machining requirements of different radial dimensions. When the vertical adjustment mechanism 306 is working, it can drive the grinding mechanism 304 connected to it to rise and fall along the height direction of the support plate 3012, accurately adjust the relative height between the grinding mechanism 304 and the contact surface 101 of the steam seal ring arc segment 100, thereby accurately controlling the axial grinding thickness of the contact surface 101. The horizontal adjustment mechanism 305 and the vertical adjustment mechanism 306 work together to achieve precise adjustment of the operating platform 302 and the grinding mechanism 304, further improving the grinding accuracy of the contact surface 101 of the steam seal ring arc segment 100, adapting to the grinding requirements under different processing scenarios. At the same time, the stable structure formed by the bearing seat 3011 and the support plate 3012 ensures the stability of the entire device structure and the convenience of adjustment, indirectly improving processing efficiency, ensuring that the thickness and fitting accuracy of the contact surface 101 after grinding meet the requirements, and thus ensuring the stability and reliability of the steam seal gap.

[0029] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figures 2 to 4 As shown, the horizontal adjustment mechanism 305 includes a horizontal slider 3051, a horizontal fixing block 3052, a horizontal lead screw 3053, a horizontal scale 3054, and a horizontal handle 3055. The horizontal slider 3051 is slidably engaged with the support base 3011, and the operating platform 302 is fixedly mounted on the horizontal slider 3051. A horizontal groove extending along the length of the support base 3011 is provided at the part of the support base 3011 that is slidably engaged with the horizontal slider 3051. The horizontal fixing block 3052 and the horizontal slider 3055... 1. Fixed connection: The horizontal fixed block 3052 is slidably disposed in the horizontal slide groove and threadedly engaged with the horizontal lead screw 3053; the horizontal lead screw 3053 passes through the bearing seat 3011 and engages with the horizontal scale 3054; the horizontal handle 3055 is installed at the end of the horizontal lead screw 3053; rotating the horizontal handle 3055 can drive the horizontal lead screw 3053 to rotate, thereby driving the horizontal fixed block 3052, the horizontal slider 3051 and the operating platform 302 to move synchronously along the length direction of the bearing seat 3011.

[0030] In this embodiment, by setting a horizontal slider 3051, a horizontal fixing block 3052, a horizontal lead screw 3053, a horizontal scale 3054, and a horizontal handle 3055, a precise and reliable structural support is provided for the movement and adjustment of the operating platform 302. The horizontal slider 3051 is slidably engaged with the support seat 3011, and the operating platform 302 is fixedly mounted on the horizontal slider 3051. A horizontal groove extending along the length of the support seat 3011 provides a guiding function for the sliding of the horizontal fixing block 3052. The horizontal fixing block 3052 is fixedly connected to the horizontal slider 3051 and threadedly engaged with the horizontal lead screw 3053. The horizontal lead screw 3053 passes through the support seat 3011 and engages with the horizontal scale 3054. The horizontal handle 3055 is mounted on the end of the horizontal lead screw 3053. Rotating the horizontal handle 3055 can drive the horizontal lead screw 3053 to rotate, thereby driving the horizontal fixing block 3052 and the horizontal slider 3055. The operating platform 302 moves synchronously along the length of the support 3011. Since the length of the support 3011 is the width of the operating platform 302, the movement of the operating platform 302 can precisely adjust the radial machining position of the steam seal ring arc segment 100, adapting to machining requirements of different radial dimensions. At the same time, the horizontal scale 3054 can assist the operator in accurately controlling the moving distance of the operating platform 302, further improving the adjustment accuracy. The entire horizontal adjustment mechanism 305 has a simple structure and is easy to operate. Together with the vertical adjustment mechanism 306, it realizes the precise adjustment of the operating platform 302 and the grinding mechanism 304, further improving the grinding accuracy of the contact surface 101 of the steam seal ring arc segment 100, adapting to the grinding requirements under different processing scenarios, ensuring the stability of the entire device structure and the convenience of adjustment, indirectly improving the processing efficiency, ensuring that the thickness and fitting accuracy of the contact surface 101 after grinding meet the requirements, and thus ensuring the stability and reliability of the steam seal gap.

[0031] It is understood that the horizontal adjustment mechanism 305 of the sealing component grinding device 300 includes a horizontal slider 3051, a horizontal fixing block 3052, a horizontal lead screw 3053, a horizontal scale 3054, and a horizontal handle 3055. The upper surface of the support seat 3011 near the operating platform 302 is provided with continuous protrusions, which extend along the length of the support seat 3011. The lower surface of the horizontal slider 3051 near the protrusions is provided with a dovetail groove, which passes through the horizontal slider 3051 along the length of the support seat 3011 and slides in cooperation with the protrusions on the upper surface of the support seat 3011. The operating platform 302 is fixedly mounted on the horizontal slider 3051. The upper surface of the protrusion has a groove extending along the length of the support 3011. This groove is a horizontal sliding groove. The horizontal fixing block 3052 is slidably disposed in the horizontal sliding groove. The center of the horizontal fixing block 3052 has a threaded hole. The horizontal lead screw 3053 passes through the horizontal sliding groove of the support 3011 and engages with the threaded hole of the horizontal fixing block 3052. The horizontal fixing block 3052 serves as a transmission component that converts the rotational motion of the horizontal lead screw 3053 into linear motion and is fixedly connected to the horizontal slider 3051. One end face of the support 3011 has a bearing hole. A bearing is installed in the bearing hole with an interference fit. The horizontal lead screw 3053 passes through the inner ring of the bearing to achieve rotational engagement with the support 3011. The position on the support 3011 corresponding to the insertion position of the horizontal lead screw 3053 is a through hole structure to ensure that the horizontal lead screw 3053 has no radial offset when rotating along its own axis. The horizontal dial 3054 is a sleeve-shaped structure with graduation markings, coaxially sleeved and fixed to the outside of the horizontal lead screw 3053. The horizontal pad is sleeved on the horizontal lead screw 3053, with one end attached to the outer end face of the bearing seat 3011 and the other end attached to the end face of the horizontal dial 3054. The horizontal dial 3054 is located between the horizontal pad and the horizontal handle 3055, and the horizontal handle 3055 is installed at the end of the horizontal lead screw 3053.

[0032] Understandably, when the horizontal adjustment mechanism 305 is working, the operator rotates the horizontal handle 3055, causing the horizontal lead screw 3053 to rotate circumferentially around its own axis. The bearing in the bearing hole of the bearing seat 3011 provides stable rotational support for the horizontal lead screw 3053. The through-hole structure restricts the radial offset of the horizontal lead screw 3053, ensuring that the horizontal lead screw 3053 only rotates circumferentially and does not move horizontally linearly with the operating platform 302. The horizontal pad both axially fixes the bearing and provides axial limit for the horizontal scale 3054, ensuring that the horizontal scale 3054 does not move axially when rotating synchronously with the horizontal lead screw 3053. The operator can accurately control the adjustment amount through the scale markings on the horizontal scale 3054. The rotational motion of the horizontal lead screw 3053 is converted into linear motion through its engagement with the central threaded hole of the horizontal fixed block 3052, which drives the horizontal fixed block 3052 to move linearly along the horizontal slide groove. The horizontal fixed block 3052 synchronously drives the horizontal slider 3051 to slide along the protrusion on the support seat 3011. The dovetail groove and the protrusion engagement structure ensure that the horizontal slider 3051 slides without deviation or shaking. Finally, it drives the operating platform 302 fixed on the horizontal slider 3051 to move synchronously and smoothly along the length direction of the support seat 3011, so as to achieve precise adjustment of the position of the operating platform 302.

[0033] In the above embodiments, see Figure 3 and Figure 4 As shown, a first set screw hole is provided on one side of the horizontal slider 3051; the part of the bearing seat 3011 that slides with the horizontal slider 3051 has a plurality of first insertion holes on the side corresponding to the first set screw hole. The first set screw hole can correspond to the first insertion hole and allow the set screw to be inserted, so as to realize the positioning between the horizontal slider 3051 and the bearing seat 3011.

[0034] It is understood that multiple first set screw holes are provided on one side of the horizontal slider 3051. These multiple first set screw holes are arranged along the length direction of the support 3011. A first insertion block is provided on the side of the protrusion on the support 3011 that slides with the horizontal slider 3051, corresponding to the first set screw holes. Multiple first insertion holes are provided on the first insertion block along the length direction of the support 3011. These first insertion holes correspond to the positions of the first set screw holes on the horizontal slider 3051, allowing for the insertion of set screws. The implementation method involves multiple first set screw holes evenly arranged on one side of the horizontal slider 3051, and the first insertion block is fixedly set on the side of the protrusion corresponding to the first set screw holes. Multiple first insertion holes are evenly spaced on the first insertion block. The working principle is that when the horizontal adjustment mechanism 305 drives the horizontal slider 3051 and the operating platform 302 to move to a suitable position along the length direction of the support 3011 via the horizontal handle 3055, the horizontal lead screw 3053, and the horizontal fixing block 3052, the operator inserts the set screw into the horizontal slider 3051. The corresponding first set screw hole is inserted through the first set screw hole into the corresponding first insertion hole on the first insertion block, thereby achieving precise positioning between the horizontal slider 3051 and the support seat 3011. This can firmly fix the relative position of the horizontal slider 3051 and the support seat 3011, preventing the horizontal slider 3051 from sliding and shifting along the protrusion on the support seat 3011 during the grinding process. This also avoids displacement of the operating platform 302, ensuring the stability of the radial machining position of the steam seal ring arc segment 100, and further improving the grinding accuracy of the contact surface 101 of the steam seal ring arc segment 100. At the same time, this positioning structure is simple and convenient, and does not affect the adjustment operation of the horizontal adjustment mechanism 305. It retains the advantages of the horizontal adjustment mechanism 305 in precise adjustment and adapting to different radial size processing requirements, while strengthening the stability of the entire device structure through reliable positioning. This avoids grinding errors caused by the offset of the operating platform 302, ensuring that the thickness and fitting accuracy of the contact surface 101 after grinding meet the requirements, thereby ensuring the stability and reliability of the steam seal gap and indirectly improving processing efficiency.

[0035] Furthermore, in some possible embodiments disclosed in this application, the vertical adjustment mechanism 306 and the horizontal adjustment mechanism 305 have similar structural composition and working principle. The specific structural composition and transmission method of the vertical adjustment mechanism 306 will not be described in detail here. See also Figure 2 and Figure 5As shown, the vertical adjustment mechanism 306 includes a vertical slider 3061, a vertical fixing block 3062, a vertical lead screw 3063, a vertical scale 3064, and a vertical handle 3065. The vertical slider 3061 is slidably engaged with the support plate 3012, and the grinding mechanism 304 is fixedly mounted on the vertical slider 3061. A vertical groove extending along the height direction of the support plate 3012 is provided on the part of the support plate 3012 that is slidably engaged with the vertical slider 3061. The vertical fixing block 3062 and the vertical slider 3061 are... 61. Fixed connection: The vertical fixing block 3062 is slidably disposed in the vertical slide groove and threadedly engaged with the vertical lead screw 3063; the vertical lead screw 3063 passes through the support plate 3012 and engages with the vertical scale 3064; the vertical handle 3065 is installed at the end of the vertical lead screw 3063; rotating the vertical handle 3065 can drive the vertical lead screw 3063 to rotate, thereby driving the vertical fixing block 3062, the vertical slider 3061 and the grinding mechanism 304 to rise and fall synchronously along the height direction of the support plate 3012.

[0036] In the above embodiments, see Figure 2 and Figure 5As shown, a plurality of second set screw holes are provided on one side of the vertical slider 3061, and the plurality of second set screw holes are arranged along the height direction of the support plate 3012. A second insertion block is provided on the side of the support plate 3012 corresponding to the second set screw holes at the part that slides with the vertical slider 3061. The second insertion block has a plurality of second insertion holes along the height direction of the support plate 3012. These second insertion holes correspond to the positions of the second set screw holes on the vertical slider 3061, allowing for the insertion of set screws. In this embodiment, the plurality of second set screw holes are evenly arranged on one side of the vertical slider 3061, and the second insertion block is fixedly mounted on the side of the support plate 3012 corresponding to the second set screw holes, with the plurality of second insertion holes evenly spaced on the second insertion block. The working principle is as follows: When the vertical adjustment mechanism 306 drives the vertical slider 3061 and the grinding mechanism 304 to rise and fall to a suitable position along the height direction of the support plate 3012 via the vertical handle 3065, vertical lead screw 3063, and vertical fixing block 3062, the operator inserts the set screw into the corresponding second set screw hole on the vertical slider 3061, and inserts the set screw through the second set screw hole into the corresponding second insertion hole on the second insertion block. This achieves precise positioning between the vertical slider 3061 and the support plate 3012, firmly fixing the relative position of the vertical slider 3061 and the support plate 3012, and preventing the vertical slider 3061 from moving along the support plate 3012 during the grinding process. The sliding offset of 12 prevents the grinding mechanism 304 from shifting, ensuring the stability of the axial machining position of the steam seal ring arc segment 100. This further improves the grinding accuracy of the contact surface 101 of the steam seal ring arc segment 100. At the same time, this positioning structure is simple and convenient, and does not affect the adjustment operation of the vertical adjustment mechanism 306. It retains the advantages of the vertical adjustment mechanism 306 in precise adjustment and adapting to different axial dimension machining requirements, while strengthening the stability of the entire device structure through reliable positioning. This avoids grinding errors caused by the offset of the grinding mechanism 304, ensuring that the thickness and fitting accuracy of the contact surface 101 after grinding meet the requirements, thereby ensuring the stability and reliability of the steam seal gap and indirectly improving the processing efficiency.

[0037] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 6 As shown, the rotating support column 303 includes a support spindle 3031, a support sleeve 3032, a rolling bearing 3033, and an axial limiting nut 3034. The support spindle 3031 passes through the operating platform 302, the rolling bearing 3033 is sleeved on the outer circumference of the support spindle 3031, and the support sleeve 3032 is sleeved on the outer circumference of the rolling bearing 3033. The support sleeve 3032 forms a rotational fit with the support spindle 3031 through the rolling bearing 3033. The two ends of the support spindle 3031 are respectively threaded with axial limiting nuts 3034. The axial limiting nut 3034 located at the lower end of the support spindle 3031 abuts against the lower surface of the operating platform 302. The axial limiting nut 3034 located at the upper end of the support spindle 3031 abuts against the upper end face of the inner ring of the rolling bearing 3033.

[0038] In this embodiment, by providing a support mandrel 3031, a support sleeve 3032, a rolling bearing 3033, and an axial limiting nut 3034, a stable and smoothly rotating support structure is provided for the gas seal ring arc segment 100. The support mandrel 3031 passes through the operating platform 302, the rolling bearing 3033 is sleeved on the outer circumference of the support mandrel 3031, and the support sleeve 3032 is sleeved on the outer circumference of the rolling bearing 3033, so that the support sleeve 3032 forms a flexible rotational fit with the support mandrel 3031 through the rolling bearing 3033. The axial limiting nuts 3034 are threaded to both ends of the support spindle 3031. The axial limiting nut 3034 located at the lower end of the support spindle 3031 abuts against the lower surface of the operating platform 302, and the axial limiting nut 3034 located at the upper end of the support spindle 3031 abuts against the upper end face of the inner ring of the rolling bearing 3033. This can firmly fix the relative positions of the support spindle 3031, the rolling bearing 3033 and the support sleeve 3032, prevent axial movement or loosening of the components, and ensure the stability of the overall structure of the rotating support column 303. This structure allows the support sleeve 3032 to rotate smoothly as the steam seal ring arc segment 100 is manually pushed, effectively reducing the movement resistance during the pushing process. Simultaneously, it ensures that the back arc surface 102 of the steam seal ring arc segment 100 remains stably in contact with the support sleeve 3032, preventing pushing jams and support misalignment. This, in turn, guarantees the stability of the grinding process and the grinding accuracy of the contact surface 101 of the steam seal ring arc segment 100. Furthermore, the threaded connection of the axial limit nut 3034 facilitates the disassembly and repositioning of the rotating support column 303, adapting to the support requirements of different specifications of steam seal ring arc segments 100. Combined with the precise adjustment of the horizontal adjustment mechanism 305 and the vertical adjustment mechanism 306, this further enhances the processing adaptability and convenience of the entire device. It ensures that the thickness and fit accuracy of the contact surface 101 of the steam seal ring arc segment 100 after grinding meet the requirements, thereby guaranteeing a stable and reliable steam seal gap, reducing air leakage and the risk of collision failure, and indirectly improving processing efficiency.

[0039] It is understood that the rotating support column 303 of the sealing component grinding device 300 includes a support spindle 3031, a support sleeve 3032, a rolling bearing 3033, an axial limiting nut 3034, a spacer 3035, and a shaft washer 3036. There are two rolling bearings 3033 and two stop surfaces are provided on the inner wall of the support sleeve 3032. A support spindle 3031 is inserted through the operating platform 302. A bearing pad 3036 is fitted onto the support spindle 3031 and located on the upper surface of the operating platform 302. The lower end face of the bearing pad 3036 abuts against the upper surface of the operating platform 302, and the upper end face of the bearing pad 3036 abuts against the lower end face of the inner ring of the rolling bearing 3033 located below. The bearing pad 3036 is used to raise the support sleeve 3032, so that a certain gap is formed between the support sleeve 3032 and the operating platform 302, so as to avoid contact friction between the support sleeve 3032 and the operating platform 302 when the support sleeve 3032 rotates, and ensure that the support sleeve 3032 can rotate smoothly without generating additional wear. Two rolling bearings 3033 are fitted around the outer periphery of the support spindle 3031 and located above the bearing pad 3036. A spacer 3035 is fitted onto the support spindle 3031 and located between the two rolling bearings 3033 to separate them and prevent them from contacting and rubbing against each other during rotation, thus affecting their rotational flexibility. A support sleeve 3032 is fitted around the outer periphery of the two rolling bearings 3033. One stop surface of the inner wall of the support sleeve 3032 abuts against the lower end face of the outer ring of the upper rolling bearing 3033, and the other stop surface abuts against the upper end face of the outer ring of the lower rolling bearing 3033, achieving precise axial positioning of the two rolling bearings 3033. Axial limiting nuts 3034 are threaded to both ends of the support spindle 3031. The axial limiting nut 3034 at the lower end of the support spindle 3031 abuts against the lower surface of the operating platform 302, and the axial limiting nut 3034 at the upper end of the support spindle 3031 abuts against the upper end face of the inner ring of the upper rolling bearing 3033. Through the axial limiting nuts 3034 at both ends, in conjunction with the bearing pad 3036 and the two stop surfaces on the inner wall of the support sleeve 3032, the support spindle 3031, bearing pad 3036, two rolling bearings 3033, spacer 3035 and support sleeve 3032 are firmly fixed into a whole to prevent axial movement or loosening of the components.

[0040] It is understandable that the working principle of the rotating support column 303 is as follows: by setting up a support mandrel 3031, a support sleeve 3032, rolling bearings 3033, axial limiting nuts 3034, spacers 3035, and shaft washers 3036, a stable and smoothly rotating support structure is provided for the gas seal ring arc segment 100. The support mandrel 3031, as a support component, passes through the operating platform 302 and is fixed to the operating platform 302 by the axial limiting nuts 3034 at both ends. The shaft washers 3036 raise the support sleeve 3032 to prevent it from rubbing against the operating platform 302. The spacers 3035 separate the two rolling bearings 3033 to ensure their rotational flexibility. The two rolling bearings 3033 enable flexible rotational cooperation between the support sleeve 3032 and the support mandrel 3031, allowing the support sleeve 3032 to rotate smoothly around the support mandrel 3031. When the steam seal ring arc segment 100 is placed on the support sleeve 3032, its back arc surface 102 is in contact with the outer circumferential surface of the support sleeve 3032. When the operator manually pushes the steam seal ring arc segment 100, the frictional force generated between the steam seal ring arc segment 100 and the support sleeve 3032 causes the support sleeve 3032 to rotate around the support spindle 3031. The rolling bearing 3033 further reduces the frictional resistance when the support sleeve 3032 rotates, ensuring a smooth and uninterrupted pushing process. At the same time, the cooperation between the axial limiting nuts 3034 at both ends, the shaft washer 3036, and the stop surface on the inner wall of the support sleeve 3032 ensures the overall structural stability of the rotating support column 303, with no axial movement or loosening of any components. This ensures that the back arc surface 102 of the steam seal ring arc segment 100 is always stably in contact with the support sleeve 3032, avoiding support offset, and thus ensuring the stability of the grinding process and the grinding accuracy of the contact surface 101 of the steam seal ring arc segment 100. In addition, the threaded connection of the axial limiting nut 3034 facilitates the disassembly and reassembly and position adjustment of the rotating support column 303, adapting to the support requirements of different specifications of steam seal ring arc segments 100. Combined with the precise adjustment of the horizontal adjustment mechanism 305 and the vertical adjustment mechanism 306, it further improves the processing adaptability and convenience of the entire device, ensuring that the thickness and fitting accuracy of the contact surface 101 of the steam seal ring arc segment 100 after grinding meet the requirements, thereby ensuring the stability and reliability of the steam seal gap, reducing air leakage loss and the risk of collision and grinding failure, and indirectly improving processing efficiency.

[0041] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 and Figure 7As shown, the operating platform 302 has multiple mounting holes 3021, which are corresponding to multiple rotating support columns 303 for the support mandrel 3031 of the rotating support column 303 to pass through and be installed. Some of the mounting holes 3021 are elongated holes, and the extension direction of the elongated holes is perpendicular to the manual pushing direction of the steam seal ring arc segment 100 along the operating platform 302 from one side to the other. The support mandrel 3031 can be adjusted in position along the extension direction of the elongated holes to adapt to steam seal ring arc segments 100 with different radii of curvature.

[0042] In this embodiment, multiple mounting holes 3021 are provided on the operating platform 302, each corresponding to a different rotating support column 303. This provides a stable mounting position for the support mandrel 3031 of the rotating support column 303, ensuring that the rotating support column 303 can be firmly installed on the operating platform 302, thereby providing reliable support for the gas seal ring arc segment 100. Some of the mounting holes 3021 are elongated holes, extending in the direction of the length of the bearing seat 3011. The support mandrel 3031 can be adjusted along the extension direction of the elongated hole, allowing the position of the rotating support column 303 to be flexibly adjusted to accommodate gas seal ring arc segments 100 with different radii of curvature, thus expanding the processing and adaptation range of the entire sealing component grinding device 300. Meanwhile, considering the structure of the rotating support column 303, which includes the support mandrel 3031, support sleeve 3032, rolling bearing 3033, axial limiting nut 3034, spacer 3035, and shaft washer 3036, after adjusting the position of the support mandrel 3031, the axial limiting nut 3034 ensures the overall stability of the rotating support column 303 after adjustment, with no axial movement or loosening of any components. This ensures that the rotating support column 303 can still provide stable and smooth self-rotating support for the gas seal ring arc segment 100 with different radii of curvature, avoiding jamming or support offset during the pushing process of the gas seal ring arc segment 100, and further improving the stability of the grinding process and the grinding accuracy of the contact surface 101 of the gas seal ring arc segment 100.

[0043] Understandably, the operating platform 302 of the sealing component grinding device 300 has multiple mounting holes 3021 for installing rotating support columns 303. These mounting holes 3021 correspond one-to-one with the rotating support columns 303, allowing the support mandrel 3031 of the rotating support columns 303 to pass through and be installed. Specifically, two circular mounting holes 3021 are symmetrically distributed at the inner center of the operating platform 302. Around these two circular mounting holes 3021, two elongated mounting holes 3021 are provided on each side, forming a support installation layout suitable for different specifications of steam seal ring arc segments 100. All the elongated mounting holes 3021 extend along the length of the bearing seat 3011, allowing the support mandrel 3031 to move freely within the extension range of the elongated mounting holes 3021, enabling flexible adjustment of the installation position. The circular mounting holes 3021 provide a fixed installation reference for the rotating support column 303 at the core support position, ensuring the core stability of the support structure.

[0044] It is understandable that the working principle of the mounting hole 3021 structure of the operating platform 302 is as follows: the circular mounting hole 3021 provides a fixed mounting point for the central rotating support column 303, making it the reference for supporting the steam seal ring arc segment 100; the elongated mounting holes 3021 on both sides provide position adjustment space for the other rotating support columns 303. When machining steam seal ring arc segments 100 with different radii of curvature, the operator can adjust the position of the support mandrel 3031 of the corresponding rotating support column 303 along the extension direction of the elongated mounting hole 3021 according to the actual curvature of the steam seal ring arc segment 100, thereby changing the arc curvature of the overall arrangement of multiple rotating support columns 303, so that the outer circumferential surface of the support sleeve 3032 of all rotating support columns 303 can jointly fit the back arc surface 102 of the steam seal ring arc segment 100 with the corresponding radius of curvature. After the position adjustment is completed, the axial limiting nuts 3034 at both ends of the rotating support column 303 are locked and fixed, so that the support spindle 3031 and the operating platform 302 form a stable connection, ensuring that the position of the rotating support column 303 does not shift during the pushing of the steam seal ring arc segment 100.

[0045] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 As shown, the sealing component grinding device 300 also includes a dial indicator 307, which includes a telescopic sleeve, a measuring rod, and a measuring head. The telescopic sleeve is fixedly inserted through the support plate 3012 and extends toward the operating platform 302. The measuring rod is telescopically installed inside the telescopic sleeve. The measuring head is fixedly installed at one end of the measuring rod toward the operating platform 302. During the entire process of manually pushing the steam seal arc segment 100 along the operating platform 302 from one side to the other, the measuring head remains in contact with the back arc surface 102 of the steam seal arc segment 100.

[0046] In this embodiment, a dial indicator 307 is added to the sealing component grinding device 300. The dial indicator 307 includes a telescopic sleeve, a measuring rod, and a measuring head. The telescopic sleeve is fixedly inserted through the support plate 3012 and extends towards the operating platform 302. The measuring rod is telescopically installed inside the telescopic sleeve, and the measuring head is fixedly installed at the end of the measuring rod facing the operating platform 302. It can maintain contact with the back arc surface 102 of the steam seal ring arc segment 100 throughout the entire process of manually pushing the steam seal ring arc segment 100 from one side to the other along the operating platform 302. It can collect the position change data of the back arc surface 102 of the steam seal ring arc segment 100 in real time, intuitively reflect the support status and running stability of the steam seal ring arc segment 100, effectively monitor whether there is support offset or abnormal jumping during the pushing process, ensure that the thickness of the steam seal ring arc segment 100 after grinding is uniform and reliable, simplify the detection process, improve the controllability and stability of processing quality, ensure the stability and reliability of the steam seal gap, and reduce the risk of air leakage loss and collision failure.

[0047] Understandably, the dial indicator 307 added to the sealing component grinding device 300 includes a telescopic sleeve, a measuring rod, and a measuring head. The telescopic sleeve passes through the support plate 3012 and extends towards the operating platform 302. Its passing part is locked and fixed by a set screw, thereby achieving a stable installation and position locking of the dial indicator 307 on the support plate 3012. The measuring rod adopts a telescopic structure and is set inside the telescopic sleeve, which can reciprocate linearly along the extension direction of the telescopic sleeve. The measuring head is fixedly set at one end of the measuring rod facing the operating platform 302. Its setting position corresponds to the pushing trajectory of the steam seal ring arc segment 100 on the operating platform 302, ensuring that during the entire process of manually pushing the steam seal ring arc segment 100 from one side to the other along the operating platform 302, the measuring head can be in contact with the back arc surface 102 of one end of the steam seal ring arc segment 100 and maintain the contact state until it is in contact with the back arc surface 102 of the other end of the steam seal ring arc segment 100.

[0048] Understandably, the dial indicator 307 works by relying on the fixed installation base of the telescopic sleeve on the support plate 3012. When the operator places the steam seal ring arc segment 100 on the rotating support column 303 of the operating platform 302 and begins to manually push it, the back arc surface 102 of the steam seal ring arc segment 100 will continuously press against the measuring head, pushing the measuring rod to make adaptive telescopic movements along the telescopic sleeve. Throughout the entire process of pushing the steam seal ring arc segment 100 from one side of the operating platform 302 to the other, the measuring head always remains in contact with the back arc surface 102. The dial indicator 307 can provide real-time feedback on the positional fluctuation of the back arc surface 102 of the steam seal ring arc segment 100 through the telescopic extension of the measuring rod, intuitively reflecting whether the steam seal ring arc segment 100 has experienced support offset, jumping, or abnormal fit of the rotating support column 303 during the grinding process. Operators can promptly determine whether the grinding accuracy meets the standard based on the changes in the dial gauge 307 reading. If a deviation occurs, the pushing force and pushing direction can be quickly adjusted to ensure that the steam seal ring arc segment 100 maintains a stable support state throughout the grinding process. This further improves the grinding accuracy and consistency of the contact surface 101 of the steam seal ring arc segment 100, ensuring that the ground steam seal ring arc segment 100 meets the assembly requirements, thereby ensuring the stable and reliable steam seal gap.

[0049] In the above embodiments, see Figure 2 As shown, the support base 3011 is provided with a positioning block 308, and the positioning block 308 has a through hole for the measuring rod to pass through. The positioning block 308 is used to radially limit and guide the measuring rod of the dial indicator 307.

[0050] Understandably, by setting a positioning block 308 on the bearing seat 3011, and opening a through hole on the positioning block 308 for the measuring rod to pass through, the positioning block 308 can accurately limit and guide the measuring rod of the dial indicator 307 radially, ensuring that the measuring rod maintains stable coaxiality when it makes reciprocating linear motion inside the telescopic sleeve. This effectively avoids radial offset or shaking of the measuring rod due to uneven force or its own weight, thereby ensuring that the measuring head is always in an accurate measuring position when it is in contact with the back arc surface 102 of the gas seal ring arc segment 100 and pushed along with it.

[0051] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0052] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
