DETAILED DESCRIPTION

[0024] The technical scheme of the utility model will be further described in detail below with specific examples and in conjunction with the drawings, and the described examples are only part of the examples of the utility model, not all examples.

[0025] Example 1: Refer to Figures 1 to 4 A slide valve herringbone arc alignment mechanism mainly consists of a base 4, a side support seat 5, a support plate 1, a crossbeam 2, a slide valve 11 and an alignment sharp mouth 8 and other key components. The design of this mechanism fully considers the accuracy and operational convenience in the slide valve alignment process, and through the synergistic effect of various components, it realizes efficient and accurate alignment function.

[0026] The base 4 is the foundation of the entire mechanism, and its two sides are respectively provided with side support seats 5. The main function of the side support seat 5 is to provide stable support for the mechanism to ensure that the accuracy will not be affected by external force or vibration during the alignment process. Above the base 4, a support plate 1 is installed, and the front end of the support plate 1 is designed with two holes, which are a double round hole 7 and a lower hole 13. The shape of the double round hole 7 matches the cross section of the crossbeam 2, and the crossbeam 2 is fixed on the support plate 1 through the double round hole 7, and the axis of the crossbeam 2 is completely coincided with the axis of the double round hole 7. This design not only ensures the stability of the crossbeam 2 in the mechanism, but also ensures its accuracy during operation, providing a reliable foundation for subsequent alignment operation.

[0027] In the lower hole 13, the slide valve 11 is placed. By placing the slide valve 11 in the lower hole 13, accurate positioning of the slide valve can be realized, providing a prerequisite for subsequent alignment operation. In addition, the crossbeam 2 is specially provided with an alignment sharp mouth 8. The alignment sharp mouth 8 is one of the key components of the mechanism, and its main function is to contact with the upper end face 9 of the slide valve 11, and to realize the alignment operation of the slide valve through accurate adjustment. This design enables the alignment sharp mouth 8 to directly act on the slide valve 11, thereby realizing high-precision alignment.

[0028] The middle part of the crossbeam 2 is designed as a concave part 16. A positioning pin shaft 15 is installed on the concave part 16. A dial gauge 14, a high-precision measuring tool, is connected to the positioning pin shaft 15. Through this design, the dial gauge 14 can achieve accurate positioning and measurement through the positioning pin shaft 15. When the positioning pin shaft 15 rotates, it will drive the alignment sharp edge 8 to swing. This linkage mechanism enables the alignment sharp edge 8 to fine-tune the slide valve 11 under the precise control of the dial gauge 14. The alignment sharp edge 8 contacts the upper end surface 9 of the slide valve, and through the precise measurement and control of the dial gauge 14, the dial gauge 14 is swung back and forth, so that the change of the dial gauge 14 is equal. This design not only improves the accuracy of slide valve alignment, but also greatly improves the convenience and reliability of operation.

[0029] During actual operation, the operator can accurately adjust the position of the alignment sharp edge 8 by observing the reading of the dial gauge 14, thereby achieving accurate alignment of the slide valve 11. This design not only improves the accuracy of slide valve alignment, but also greatly improves the convenience and reliability of operation, making the entire alignment process more efficient and accurate.

[0030] Embodiment 2: Refer to Figures 1 to 4 A slide valve X-shaped arc alignment mechanism mainly consists of a base 4, side support seats 5, a support plate 1, a crossbeam 2, a slide valve 11, and an alignment sharp edge 8, etc. The mechanism fully considers the high-precision requirement of slide valve alignment and the convenience of operation during the design process, and through the close cooperation of various components, it realizes efficient and accurate alignment function. The base 4 is equipped with side support seats 5 on both sides. The main function of the side support seats 5 is to provide stable support for the entire mechanism, ensuring that the alignment accuracy will not be affected by external interference or vibration during the alignment process. Above the base 4, there is a support plate 1 fixed, and the front end of the support plate 1 is designed with two holes: a double circular hole 7 and a lower hole 13. The shape of the double circular hole 7 is matched with the cross section of the crossbeam 2, and the crossbeam 2 is fixed on the support plate 1 through this hole, and the axis of the crossbeam 2 is completely aligned with the axis of the double circular hole 7. This design not only ensures the stability of the crossbeam 2 in the mechanism, but also provides a solid foundation for its accuracy in subsequent operation.

[0031] The slide valve 11 is placed in the lower hole 13, which realizes the accurate positioning of the slide valve and lays a foundation for the subsequent alignment operation. In addition, the crossbeam 2 is specially equipped with an alignment sharp edge 8, which is one of the key components of the mechanism. The main function of the alignment sharp edge 8 is to contact the upper end surface 9 of the slide valve 11 and achieve the alignment operation of the slide valve through accurate adjustment. This design enables the alignment sharp edge 8 to directly act on the slide valve 11, thereby realizing high-precision alignment.

[0032] The middle part of the crossbeam 2 is designed as a concave part 16, on which a positioning pin shaft 15 is installed. A high-precision dial gauge 14 is connected to the positioning pin shaft 15. Through this design, the dial gauge 14 can realize accurate positioning and measurement through the positioning pin shaft 15. When the positioning pin shaft 15 rotates, it will drive the alignment sharp mouth 8 to swing. This linkage mechanism enables the alignment sharp mouth 8 to fine-tune the slide valve 11 under the accurate control of the dial gauge 14.

[0033] After the alignment sharp mouth 8 contacts the upper end surface 9 of the slide valve, the swing amplitude of the dial gauge 14 is adjusted through accurate measurement and control, and the change amount is kept consistent, thereby realizing accurate alignment of the slide valve 11. This design not only significantly improves the accuracy of slide valve alignment, but also greatly improves the convenience and reliability of operation. The operator can accurately adjust the position of the alignment sharp mouth 8 by observing the reading of the dial gauge 14, thereby realizing accurate alignment of the slide valve 11. This design not only improves the alignment accuracy, but also greatly improves the convenience and reliability of operation, making the entire alignment process more efficient and accurate, and providing a strong guarantee for the accurate installation and debugging of the slide valve.

[0034] The two sides of the slide valve 11 are fixed by the slide valve side end positioning piece 10. The slide valve side end positioning piece 10 is a specially designed component, which mainly ensures the stable position of the slide valve 11 during alignment. The slide valve side end positioning piece 10 is connected to the support plate 1, firmly fixing the slide valve 11 on the support plate 1, thereby providing reliable support for subsequent alignment operations.

[0035] The overall structure of the slide valve side end positioning piece 10 is designed as an L shape, which not only saves space but also provides sufficient support. One end of the L-shaped structure extends a positioning sharp mouth 17, which tightly contacts the side surface of the slide valve 11 and accurately positions the slide valve 11. This design ensures that the slide valve 11 does not move laterally during alignment, thereby ensuring the accuracy and reliability of the alignment operation.

[0036] In addition to the fixation of the slide valve 11 on both sides by the slide valve side end positioning piece 10, the bottom of the slide valve 11 is also fixed by the slide valve bottom end positioning piece 12. The slide valve bottom end positioning piece 12 is another specially designed component, which mainly ensures the stability of the slide valve 11 at the bottom. One side of the slide valve bottom end positioning piece 12 is fixed on the side support seat 5, which provides firm support for the slide valve 11 at the bottom. Through the fixation of the slide valve bottom end positioning piece 12, the slide valve 11 does not move up and down during alignment, thereby further improving the accuracy and stability of the alignment.

[0037] Through the double fixation of the slide valve side end positioning piece 10 and the slide valve bottom end positioning piece 12, the slide valve 11 is fully supported and positioned during the alignment process. This design not only improves the positioning accuracy of the slide valve 11, but also greatly enhances the stability and reliability of the entire alignment mechanism.

[0038] Embodiment 3: Reference Figures 1 to 4 A slide valve chevron alignment mechanism mainly consists of a base 4, a side support seat 5, a support plate 1, a crossbeam 2, a slide valve 11, and a key component such as an alignment sharp mouth 8. During the design process, the mechanism fully considers the high precision requirement of slide valve alignment and the convenience of operation, and through the close cooperation and collaborative work of each component, it realizes efficient and precise alignment function.

[0039] The base 4 is installed with a side support seat 5 on both sides. The main function of the side support seat 5 is to provide stable support for the entire mechanism, ensuring that the alignment accuracy will not be affected by external interference or vibration during the alignment process. This stable support structure lays a solid foundation for subsequent operation. Above the base 4, there is a support plate 1 fixed, and the front end of the support plate 1 is designed with two holes: a double circular hole 7 and a lower hole 13. The shape of the double circular hole 7 is matched with the cross section of the crossbeam 2, and the crossbeam 2 is fixed on the support plate 1 through the hole, and the axis of the crossbeam 2 is completely aligned with the axis of the double circular hole 7. The slide valve 11 is placed in the lower hole 13, which realizes the precise positioning of the slide valve and lays a foundation for subsequent alignment operation. In addition, the crossbeam 2 is specially equipped with an alignment sharp mouth 8, which is one of the key components of the mechanism. The main function of the alignment sharp mouth 8 is to contact with the upper end surface 9 of the slide valve 11, and to realize the alignment operation of the slide valve through accurate adjustment. This design makes the alignment sharp mouth 8 can directly act on the slide valve 11, so as to realize high-precision alignment. Through this ingenious design, the alignment sharp mouth 8 can fine-tune the slide valve 11, ensuring that it meets the required precision requirements during the alignment process.

[0040] The middle part of the crossbeam 2 is designed as a concave part 16, on which a positioning pin shaft 15 is installed. A high-precision dial gauge 14 is connected to the positioning pin shaft 15. Through this design, the dial gauge 14 can realize accurate positioning and measurement through the positioning pin shaft 15. When the positioning pin shaft 15 rotates, it will drive the alignment sharp mouth 8 to swing. This linkage mechanism enables the alignment sharp mouth 8 to fine-tune the slide valve 11 under the accurate control of the dial gauge 14. After the alignment sharp mouth 8 contacts the upper end surface 9 of the slide valve, the swing amplitude of the dial gauge 14 is adjusted through accurate measurement and control, so that the variation remains consistent, thereby realizing accurate alignment of the slide valve 11. This design not only significantly improves the accuracy of slide valve alignment, but also greatly improves the convenience and reliability of operation. The operator can accurately adjust the position of the alignment sharp mouth 8 by observing the reading of the dial gauge 14, thereby realizing accurate alignment of the slide valve 11. This design not only improves the alignment accuracy, but also greatly improves the convenience and reliability of operation, making the entire alignment process more efficient and accurate, providing a strong guarantee for the accurate installation and debugging of the slide valve.

[0041] The two sides of the slide valve 11 are fixed by the slide valve side end positioning member 10. The slide valve side end positioning member 10 is a specially designed component, which mainly functions to ensure that the slide valve 11 maintains a stable position during alignment. The slide valve side end positioning member 10, through connection with the support plate 1, firmly fixes the slide valve 11 on the support plate 1, thereby providing reliable support for subsequent alignment operations. This design effectively prevents the slide valve 11 from moving laterally during alignment, ensuring the accuracy and reliability of the alignment operation.

[0042] The overall structure of the slide valve side end positioning member 10 is designed as an L shape, which not only saves space but also provides sufficient support. One end of the L-shaped structure extends a positioning sharp mouth 17, which is in close contact with the side surface of the slide valve 11 and can accurately position the slide valve 11. This design ensures that the slide valve 11 does not move laterally during alignment, thereby ensuring the accuracy and reliability of the alignment operation. The slide valve side end positioning member 10 not only provides stable support but also provides a strong guarantee for the accurate alignment of the slide valve 11.

[0043] In addition to the fixing of the spool 11 by the spool side end positioning member 10 on both sides, the bottom of the spool 11 is also fixed by the spool bottom end positioning member 12. The spool bottom end positioning member 12 is another specially designed component, and its main function is to ensure the stability of the spool 11 at the bottom. One side of the spool bottom end positioning member 12 is fixed on the side support seat 5, and this design makes the spool 11 firmly supported at the bottom. Through the fixation of the spool bottom end positioning member 12, the spool 11 will not move up and down during the alignment process, thereby further improving the accuracy and stability of the alignment. This double-fixed design not only enhances the stability of the spool 11 during the alignment process, but also provides strong support for the efficient operation of the entire alignment mechanism.

[0044] Through the double fixation of the spool side end positioning member 10 and the spool bottom end positioning member 12, the spool 11 is fully supported and positioned during the alignment process. This design not only improves the positioning accuracy of the spool 11, but also enhances the stability and reliability of the entire alignment mechanism. Through this carefully designed structure, the spool 11 can always maintain a stable position during the alignment process, thereby ensuring high precision and efficiency of the alignment operation.

[0045] A U-shaped groove is formed between the base 4 and the support plate 1, and the inside of the U-shaped groove 3 adopts a hollow structure, which reduces the overall weight of the mechanism. The bottom height of the U-shaped groove 3 is designed to be slightly higher than the side support seats 5 at both ends, making the whole more stable. The side support seats 5 are also provided with a plurality of base fixing holes 6, and the operator can firmly fix the entire mechanism on the workbench or other support structures according to different installation requirements. At the same time, the arrangement of multiple base fixing holes 6 also provides convenience for subsequent expansion or modification. Users can choose different fixing methods according to their needs, further improving the universality and adaptability of the mechanism.
