Description

Technical Field

[0001] This invention relates to the field of hydraulic support technology, and in particular to a tooling assembly for an ear plate and a tooling assembly for a bottom adjusting sleeve. Background Technology

[0002] Hydraulic supports are key support equipment in fully mechanized coal mining faces. The bottom-adjusting sleeve assembly on its base is mainly used to install bottom-adjusting jacks. Bottom-adjusting jacks are an important component of hydraulic supports. In coal mining, especially in working faces with poor floor conditions and inclined coal seams, supports are prone to tilting after being moved. Bottom-adjusting jacks are used to adjust adjacent supports during the movement process to ensure overall synchronization and stability. The bottom-adjusting sleeve provides positioning and support space for the bottom-adjusting jacks, allowing them to be concealed inside or on the side of the base, thereby reducing underground collisions and damage from rockfalls, while also protecting the bottom-adjusting jacks.

[0003] The bottom-adjusting sleeve assembly includes a bottom-adjusting sleeve and a lug plate. The connection method involves placing the cylinder of the bottom-adjusting jack inside the bottom-adjusting sleeve, with the lug plate fixed to the side of the inner main rib. The lug plate has a pin hole, and fixation is achieved by passing a pin through the pin hole in the lug plate and the hinge hole at the jack's connecting end. However, this structure has the following drawbacks during processing and assembly: During the manufacturing process of the main rib assembly, the sleeve and ear plates are assembled separately in different assembly sequences. Operators rely solely on a combination of design dimensions and manual marking to position the sleeve and ear plates. This assembly method involves a large amount of manual labor and is prone to assembly errors in the ear plates and bottom adjusting sleeve, creating a risk that the horizontal center of the bottom adjusting sleeve and the center of the distance between the two ear plates are not perpendicular. Relying solely on visual inspection or measuring tape for positioning leads to a continuous accumulation of errors, ultimately causing uneven wear on the bottom adjusting jack after installation, severely affecting the jack's service life and the overall performance of the hydraulic support.

[0004] Therefore, there is an urgent need for a tooling assembly for ear plates and bottom adjusting sleeves that can solve the problems existing in the above-mentioned traditional assembly methods. Summary of the Invention

[0005] (a) Technical problems to be solved In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a tooling assembly for an ear plate and a tooling assembly for a bottom adjusting sleeve, which solves the technical problems of poor assembly accuracy and low assembly efficiency of the ear plate and the bottom adjusting sleeve.

[0006] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by the present invention include: A tooling assembly for an ear plate includes: a positioning element, a first positioning shaft, and a second positioning shaft; The positioning element includes a first positioning plate extending along a first direction and a second positioning plate extending along a second direction and spaced apart from the first positioning plate along the first direction. One end of the first positioning plate is provided with a positioning post extending in a third direction; The second positioning plate has a first positioning hole at one end; One end of the first positioning shaft is adapted to be inserted into the first reference hole on the inner main rib, and the other end is provided with a second positioning hole; when the first positioning shaft is inserted into the first reference hole and the positioning post abuts against the first reference surface of the inner main rib, the first positioning hole, the second positioning hole and the first pin hole of the ear plate are coaxially arranged to pass through the second positioning shaft.

[0007] It also includes a third positioning shaft, and the other end of the second positioning plate is provided with a third positioning hole. The third positioning hole is coaxially arranged with the second pin hole of the ear plate and is used to pass through the third positioning shaft.

[0008] The number of the second positioning plates is two.

[0009] A rib extending along a first direction is provided between adjacent second positioning plates, the rib being perpendicular to the first positioning plate and the second positioning plate.

[0010] A tooling assembly for a bottom adjusting sleeve includes: a fourth positioning shaft extending along a third direction and a fifth positioning shaft spaced apart from the fourth positioning shaft along the third direction; the fifth positioning shaft is perpendicular to the fourth positioning shaft. One end of the fourth positioning shaft is adapted to be inserted into the second reference hole on the inner main rib. When the fourth positioning shaft is inserted into the second reference hole, the fourth positioning shaft is coaxial with the bottom adjusting sleeve mounting hole of the outer main rib.

[0011] The length of the fifth positioning shaft matches the inner diameter of the bottom adjusting sleeve.

[0012] A method for positioning an ear plate, employing a tooling assembly for the ear plate, includes the following steps: S1: A first reference plane is formed at the bottom end of the inner main reinforcement; S2: The first reference hole is opened on the inner main reinforcement; S3: Insert one end of the first positioning shaft into the first reference hole, abut the positioning post of the positioning component against the first reference surface of the inner main rib, place the ear plate on the second positioning plate of the positioning component, and pass the second positioning shaft through the first pin hole of the ear plate, the first positioning hole of the second positioning plate and the second positioning hole of the first positioning shaft, so that the welded end of the ear plate abuts against the side of the inner main rib, thus completing the positioning of the ear plate and the first pin hole.

[0013] S4: Pass the third positioning shaft through the second pin hole of the ear plate and the third positioning hole of the second positioning plate to complete the positioning of the second pin hole.

[0014] In step S2, the first reference hole is located on the center line of the distance between the preset installation positions of the two ear plates, and on the axial center line of the preset installation position of the first pin hole of the ear plate.

[0015] A method for positioning a bottom adjusting sleeve, employing a tooling assembly for the bottom adjusting sleeve, includes the following steps: S1: A second reference hole is opened on the inner main rib. The second reference hole is located on the center line of the distance between the preset installation positions of the two ear plates and on the center line of the length of the ear plates. S2: A second reference plane is formed at the bottom of the outer main reinforcement bar, and the second reference plane of the outer main reinforcement bar is in the same plane as the first reference plane of the inner main reinforcement bar; S3: Place the inner and outer main reinforcement bars vertically on the base plate; S4: Pass the fourth positioning shaft through the bottom adjusting sleeve, and abut the two ends of the fifth positioning shaft against the inner wall of the bottom adjusting sleeve; pass one end of the fourth positioning shaft with the bottom adjusting sleeve through the bottom adjusting sleeve mounting hole of the outer main rib and insert it into the second reference hole, so that the bottom adjusting sleeve, the fourth positioning shaft and the bottom adjusting sleeve mounting hole of the outer main rib are coaxial, and the axis of the bottom adjusting sleeve is perpendicular to the center line of the spacing of the ear plate, thus completing the positioning of the bottom adjusting sleeve.

[0016] (III) Beneficial Effects The beneficial effects of this invention are as follows: The tooling assembly for the ear plate of this invention, through the mutual cooperation of the positioning component, the first positioning shaft, and the second positioning shaft, achieves rapid and precise positioning of the ear plate relative to the inner main rib in both vertical and horizontal directions. Specifically, the positioning post abuts against the first reference surface of the inner main rib, achieving vertical positioning of the positioning component; one end of the first positioning shaft inserts into the first reference hole on the inner main rib, achieving initial horizontal positioning of the positioning component; when the positioning post abuts against the first reference surface and the first positioning shaft inserts into the first reference hole, the second positioning shaft simultaneously passes through the first positioning hole on the second positioning plate, the second positioning hole on the first positioning shaft, and the first pin hole of the ear plate, making all three coaxial. This precisely fixes the position of the first pin hole of the ear plate relative to the inner main rib and ensures that the welded end of the ear plate is tightly fitted to the side of the inner main rib. This tooling assembly effectively eliminates the cumulative error of the ear plate during the positioning process. The components are simple in structure and low in manufacturing cost. The positioning operation can be completed with just plugging and shaft passing, which greatly shortens the preparation time for ear plate positioning and welding, improves welding efficiency, and ensures the consistency and repeatability of ear plate welding position in mass production, thereby effectively improving welding quality and product qualification rate.

Detailed Implementation

[0019] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0020] Example 1: like Figures 1 to 9 As shown, this embodiment provides a tooling assembly for an ear plate, including a positioning component 1, a first positioning shaft 2, and a second positioning shaft 3.

[0021] The positioning component 1 includes a first positioning plate 11 extending along a first direction a and a second positioning plate 12 extending along a second direction b and spaced apart from the first positioning plate 11 along the first direction a. The second positioning plate 12 is used to quickly position the installation height of the ear plate 7. One end of the first positioning plate 11 has a positioning post 111 extending along a third direction c on the side facing the inner main rib 9. The positioning post 111 is used to cooperate with the first reference surface 92 of the inner main rib 9 to form a positioning reference. The first direction a, the second direction b, and the third direction c are perpendicular to each other, forming a spatial rectangular coordinate system.

[0022] One end of the second positioning plate 12 has a first positioning hole 121 corresponding to the first pin hole 71 of the ear plate 7.

[0023] The outer circumferential surface of the first positioning shaft 2 is stepped. One end of the first positioning shaft 2 is used to be inserted into the first reference hole 91 on the inner main rib 9. The other end of the first positioning shaft 2 is provided with a second positioning hole 21. The first positioning hole 121 and the second positioning hole 21 are used to realize the rapid positioning of the pin hole position of the ear plate 7.

[0024] In use, one end of the first positioning shaft 2 is inserted into the first reference hole 91 on the inner main rib 9, with the first positioning shaft 2 and the first reference hole 91 undergoing a transition fit, thus fixing the first positioning shaft 2 and the inner main rib 9 together. Simultaneously, the positioning pin 111 of the positioning component 1 abuts against the first reference surface 92 of the inner main rib 9, achieving vertical positioning between the positioning component 1 and the inner main rib 9. Then, the ear plate 7 is placed on the second positioning plate 12. By passing the second positioning shaft 3 through the first pin hole 71 of the ear plate 7, the first positioning hole 121 on the second positioning plate 12, and the second positioning hole 21 of the first positioning shaft 2, with the second positioning shaft 3 undergoing a transition fit with the first positioning hole 121, the second positioning hole 21, and the first pin hole 71, the first positioning hole 121, the second positioning hole 21, and the first pin hole 71 remain coaxial, thus fixing the ear plate 7 and precisely positioning it on the inner main rib 9.

[0025] This embodiment achieves rapid and precise positioning of the ear plate 7 relative to the inner main rib 9 in both vertical and horizontal directions through the cooperation of positioning component 1, first positioning shaft 2, and second positioning shaft 3. The tooling assembly has a simple structure and is easy to operate, which can effectively ensure the accuracy and consistency of the ear plate welding position, thereby improving welding quality and production efficiency.

[0026] Example 2: Based on Example 1, such as Figure 5 As shown, the tooling assembly for positioning the ear plate 7 also includes a third positioning shaft 4. A third positioning hole 122 is provided at the other end of the second positioning plate 12 corresponding to the second pin hole 72 of the ear plate 7. When the positioning member 1 is positioned and installed on the inner main rib 9 and the ear plate 7 is placed on the second positioning plate 12, the third positioning shaft 4 passes through the second pin hole 72 and the third positioning hole 122 of the ear plate 7, making the third positioning hole 122 coaxial with the second pin hole 72 of the ear plate 7, thereby completing the positioning of the second pin hole 72 of the ear plate 7.

[0027] By simultaneously positioning at both the first pin hole 71 and the second pin hole 72 of the ear plate 7, rotation or offset of the ear plate 7 can be effectively prevented, further improving the overall positioning accuracy and reliability of the ear plate 7 and ensuring the relative position accuracy of the two pin holes of the ear plate after welding.

[0028] Example 3: like Figure 6 As shown, based on Embodiment 1, in this embodiment, the number of second positioning plates 12 is two. The two second positioning plates 12 are spaced apart on the first positioning plate 11 along the first direction a.

[0029] By setting the number of second positioning plates 12 to two, two ear plates 7 can be supported and positioned simultaneously as needed. This is suitable for scenarios where two ear plates of the hydraulic support base are simultaneously positioned and welded to the jack, thus improving the operating efficiency of the tooling components.

[0030] Example 4: Based on Embodiment 1, a rib 13 extending along the first direction a is provided between two adjacent second positioning plates 12. The rib 13 is perpendicular to the first positioning plate 11 and the second positioning plate 12.

[0031] Optionally, a rib 13 is provided between the second positioning plate 12 and the positioning post 111 of the positioning member 1.

[0032] This embodiment significantly enhances the overall structural strength and bending stiffness of the positioning component 1 by setting ribs 13 between adjacent second positioning plates 12, effectively preventing the positioning component 1 from bending or torsional deformation due to stress during long-term use, and ensuring the positioning accuracy and service life of the tooling assembly during repeated use.

[0033] Example 5: like Figures 10 to 12 As shown, this embodiment provides a tooling assembly for a bottom adjusting sleeve, including a fourth positioning shaft 5 extending along a third direction c and a fifth positioning shaft 6 spaced apart from the fourth positioning shaft 5 along the third direction c. The fifth positioning shaft 6 is perpendicular to the fourth positioning shaft 5.

[0034] One end of the fourth positioning shaft 5 is adapted to be inserted into the second reference hole 93 on the inner main rib 9, with a transition fit between the fourth positioning shaft 5 and the second reference hole 93 during insertion. In use, one end of the fourth positioning shaft 5 is inserted into the second reference hole 93 on the inner main rib 9, and the fourth positioning shaft 5 is coaxial with the bottom adjusting sleeve mounting hole 102 of the outer main rib 10. The bottom adjusting sleeve 8 is sleeved on the fourth positioning shaft 5, and both ends of the fifth positioning shaft 6 abut against the inner wall of the bottom adjusting sleeve 8, keeping the bottom adjusting sleeve 8 coaxial with the fourth positioning shaft 5. The bottom adjusting sleeve 8 can pass through the bottom adjusting sleeve mounting hole 102 of the outer main rib 10, completing the positioning of the bottom adjusting sleeve 8.

[0035] In this embodiment, the fourth positioning shaft 5 is inserted into the second reference hole 93 on the inner main rib 9, achieving precise positioning of the fourth positioning shaft 5 relative to the inner main rib 9. The fourth positioning shaft 5 is coaxially arranged with the bottom adjusting sleeve mounting hole 102 of the outer main rib 10, ensuring that the bottom adjusting sleeve 8 can accurately pass through the mounting hole of the outer main rib 10. The fifth positioning shaft 6 is perpendicular to the fourth positioning shaft 5 and spaced apart from it, and is used to abut against the inner wall of the bottom adjusting sleeve 8, ensuring the coaxiality of the bottom adjusting sleeve 8 and the fourth positioning shaft 5. This tooling assembly has a simple structure, reliable positioning, and can effectively ensure the precise position of the bottom adjusting sleeve relative to the inner and outer main ribs.

[0036] Example 6: Based on embodiment 5, the length of the fifth positioning shaft 6 matches the inner diameter of the bottom adjusting sleeve 8. That is, the dimension of the fifth positioning shaft 6 in the direction perpendicular to the fourth positioning shaft 5 is adapted to the inner diameter of the bottom adjusting sleeve 8.

[0037] In this embodiment, the length of the fifth positioning shaft 6 is set to match the inner diameter of the bottom adjusting sleeve 8. During use, both ends of the fifth positioning shaft 6 are exactly abutted against the inner wall of the bottom adjusting sleeve 8, so that the bottom adjusting sleeve 8 and the fourth positioning shaft 5 remain coaxial and relatively fixed. This effectively prevents the bottom adjusting sleeve 8 from radially shifting or tilting during the positioning process, ensures the coaxiality of the bottom adjusting sleeve 8 and the fourth positioning shaft 5, and improves the positioning accuracy of the bottom adjusting sleeve.

[0038] Example 7: like Figure 9 As shown, this embodiment provides a method for positioning an ear plate, using the tooling assembly for the ear plate 7 from embodiments 1 to 4, including the following steps: S1: A first reference plane 92 is formed at the bottom end of the inner main reinforcement 9. Specifically, The inner main rib 9 is shaped using a CNC flame cutting machine, with a 3mm margin left on the positioning reference surface. This 3mm margin is then removed by machining to create a flat reference surface, which serves as the reference for subsequent positioning. The ear plate 7 is shaped using a CNC flame cutting machine, and pin holes are formed by machining and drilling.

[0039] S2: A first reference hole 91 is made on the inner main reinforcement 9. Specifically, the first reference hole 91 is made at a predetermined position on the side of the inner main reinforcement 9 by machining.

[0040] S3: Insert one end of the first positioning shaft 2 into the first reference hole 91 on the inner main rib 9, so that the first positioning shaft 2 is fixedly connected to the inner main rib 9. Position the positioning pin 111 of the positioning component 1 against the first reference surface 92 of the inner main rib 9 to achieve positioning of the positioning component 1. Place the ear plate 7 on the second positioning plate 12 of the positioning component 1, so that the first pin hole 71 of the ear plate 7 is aligned with the first positioning hole 121 of the second positioning plate 12. Then, pass the second positioning shaft 3 through the first pin hole 71 of the ear plate 7, the first positioning hole 121 of the second positioning plate 12, and the second positioning hole 21 of the first positioning shaft 2, so that the welded end of the ear plate 7 abuts against the side of the inner main rib 9, completing the positioning of the ear plate 7 and the first pin hole 71.

[0041] This embodiment achieves precise positioning between the positioning component 1 and the inner main rib 9 by forming a first reference surface 92 and opening a first reference hole 91 at the bottom end of the inner main rib 9, and utilizing a dual positioning method of positioning pin 111 abutting against the first reference surface 92 and first positioning shaft 2 inserting into the first reference hole 91. The second positioning shaft 3 passes through the first pin hole 71 of the ear plate 7, the first positioning hole 121 of the second positioning plate 12, and the second positioning hole 21 of the first positioning shaft 2, precisely fixing the position of the first pin hole 71 of the ear plate 7 relative to the inner main rib 9, ensuring the perpendicularity of the ear plate 7 to the side of the inner main rib 9. This positioning method is simple in steps, convenient to operate, and has high positioning accuracy, effectively ensuring the consistency of the ear plate welding position and the welding quality.

[0042] Example 8: Based on Embodiment 7, the ear plate positioning method of this embodiment further includes step S4: passing the third positioning shaft 4 through the second pin hole 72 of the ear plate 7 and the third positioning hole 122 of the second positioning plate 12, thereby completing the positioning of the second pin hole 72 of the ear plate 7.

[0043] This embodiment achieves synchronous positioning of the second pin hole 72 of the ear plate 7 by adding a third positioning shaft 4, so that both pin holes of the ear plate 7 are accurately positioned, effectively preventing the ear plate 7 from rotating during the welding process, further improving the positioning accuracy and reliability of the ear plate 7, and ensuring the relative position accuracy between the two pin holes of the ear plate after welding.

[0044] Example 9: Based on embodiment 7, the first reference hole 91 is located on the center line of the distance between the preset installation positions of the two ear plates 7, and on the axial center line of the preset installation position of the first pin hole 71 of the ear plate 7, providing a reliable positioning reference for subsequent welding.

[0045] Example 10: like Figure 12 As shown, this embodiment provides a positioning method for a bottom adjusting sleeve, using the tooling assembly for the bottom adjusting sleeve 8 from embodiments 5 to 6, including the following steps: S1: A second reference hole 93 is made on the inner main rib 9. The second reference hole 93 is located on the center line of the distance between the preset installation positions of the two ear plates 7, and on the length center line of the ear plate 7. In the actual processing, since the first reference hole 91 and the second reference hole 93 are located on the same distance center line, the second reference hole 93 can be formed synchronously with the first reference hole 91 when processing the inner main rib 9 before the ear plate 7 is installed.

[0046] S2: A second reference surface 101 is formed at the bottom end of the outer main reinforcement 10. The second reference surface 101 of the outer main reinforcement 10 is in the same plane as the first reference surface 92 of the inner main reinforcement 9. By making the two reference surfaces coplanar, it is ensured that the inner main reinforcement 9 and the outer main reinforcement 10 are at the same reference height when placed on the base plate of the hydraulic support base.

[0047] S3: Place the inner main reinforcement 9 and the outer main reinforcement 10 vertically on the base plate. At this time, the first reference surface 92 of the inner main reinforcement 9 and the second reference surface 101 of the outer main reinforcement 10 are respectively in contact with the base plate.

[0048] S4: Pass the fourth positioning shaft 5 through the bottom adjusting sleeve 8, and abut both ends of the fifth positioning shaft 6 against the inner wall of the bottom adjusting sleeve 8, so that the bottom adjusting sleeve 8 and the fourth positioning shaft 5 are coaxial. Pass one end of the fourth positioning shaft 5, which is fitted with the bottom adjusting sleeve 8, through the bottom adjusting sleeve mounting hole 102 of the outer main rib 10 and insert it into the second reference hole 93 on the inner main rib 9, so that the bottom adjusting sleeve 8, the fourth positioning shaft 5 and the bottom adjusting sleeve mounting hole 102 of the outer main rib 10 are coaxial, and the axis of the bottom adjusting sleeve 8 is perpendicular to the center line of the spacing of the ear plate 7. Adjust the horizontal position of the bottom adjusting sleeve 8 so that the bottom adjusting sleeve 8 overlaps in the bottom adjusting sleeve mounting hole 102, thus completing the positioning of the bottom adjusting sleeve 8.

[0049] In addition, the bottom of the bottom adjusting sleeve 8 is provided with a stiffening plate 81. The stiffening plate 81 is vertically set on the bottom plate and fits against the bottom plate. The shape of the stiffening plate 81 is formed by CNC flame cutting, and there is an arc-shaped area in the middle, which corresponds to the bottom adjusting sleeve 8. When positioning the bottom adjusting sleeve 8, the stiffening plate 81 is placed on the bottom plate simultaneously, and the arc-shaped area of ​​the stiffening plate 81 abuts against the bottom adjusting sleeve 8. The horizontal position of the stiffening plate 81 is adjusted so that the stiffening plate 81 is located at the end of the bottom adjusting sleeve 8 near the inner main rib 9, which is used to support the bottom adjusting sleeve 8.

[0050] By creating a second reference hole 93 on the inner main reinforcement 9, a second reference surface 101, coplanar with the first reference surface 92 of the inner main reinforcement 9, is formed at the bottom end of the outer main reinforcement 10, ensuring a precise relative positional relationship between the inner and outer main reinforcements 9 and 10 when placed on the base plate. By passing the fourth positioning shaft 5 through the bottom adjusting sleeve 8 and inserting it into the second reference hole 93, while the fifth positioning shaft 6 abuts against the inner wall of the bottom adjusting sleeve 8, the bottom adjusting sleeve 8, the fourth positioning shaft 5, and the bottom adjusting sleeve mounting hole 102 of the outer main reinforcement 10 are precisely coaxial, and the axis of the bottom adjusting sleeve 8 is perpendicular to the plane of the inner main reinforcement 9 and the center line of the spacing of the ear plate 7. This positioning method is reasonable in its steps, simple in operation, and reliable in its positioning, effectively ensuring the installation accuracy of the bottom adjusting sleeve 8 relative to the inner and outer main reinforcements 9 and 10.

[0051] Example 11: This embodiment provides a more detailed description of the assembly method of the ear plate and the bottom adjusting sleeve.

[0052] First, a first reference surface 92 is machined at the bottom end of the inner main reinforcement 9, and a first reference hole 91 and a second reference hole 93 are respectively opened. A second reference surface 101 is machined at the bottom end of the outer main reinforcement 10, and the second reference surface 101 is coplanar with the first reference surface 92.

[0053] Next, the ear plate 7 is precisely positioned at the predetermined position of the inner main rib 9 using the tooling assembly for the ear plate 7, and then the ear plate 7 is welded and fixed to the inner main rib 9. After welding is completed, the second positioning shaft 3 and the third positioning shaft 4 are removed, and the positioning component 1 and the first positioning shaft 2 are dismantled.

[0054] Then, the inner main reinforcement 9 and the outer main reinforcement 10 are placed vertically on the base plate, with the first reference surface 92 of the inner main reinforcement 9 and the second reference surface 101 of the outer main reinforcement 10 respectively attached to the base plate.

[0055] The inner main reinforcement 9 and the outer main reinforcement 10 are fixed together by welding with a spacing plate 81. The spacing plate 81 is perpendicular to the inner main reinforcement 9 and the outer main reinforcement 10, and can limit the distance between the inner main reinforcement 9 and the outer main reinforcement 10.

[0056] Finally, the bottom adjusting sleeve 8 is precisely positioned between the inner main rib 9 and the outer main rib 10 using the tooling assembly for bottom adjusting sleeve 8. The stiffening plate 81 is vertically set on the base plate, and its horizontal position is adjusted so that it can support the bottom adjusting sleeve 8. The bottom adjusting sleeve 8 is then welded and fixed to the outer main rib 10, the stiffening plate 81 is welded and fixed to the bottom adjusting sleeve 8 and the base plate, and the inner main rib 9 and the outer main rib 10 are welded and fixed to the base plate.

[0057] By using the tooling assembly for the ear plate 7 and the tooling assembly for the bottom adjusting sleeve 8 in combination, precise and efficient positioning of the ear plate 7 and the bottom adjusting sleeve 8 on the inner main rib 9 and outer main rib 10 of the frame is achieved, ensuring the relative positional accuracy of each component and the welding quality. The above-mentioned tooling assembly can be reused, effectively ensuring the consistency of the welding position and improving the welding quality.
