Description

Technical Field

[0001] This invention relates to the field of coal mining technology, and in particular to a tooling assembly and installation method for installing the base connector of a hydraulic support. Background Technology

[0002] The base is a crucial component of the hydraulic support system, forming the foundation for its overall structural stability. In environments with uneven base plates, a split base is typically used, usually consisting of a left and a right base, which require connection. Traditionally, this involves welding connecting components, such as bridge plate connectors and bridge plate lugs, directly onto the main stiffening plates on opposite sides of the left and right bases before connecting them. However, welding these connectors typically involves manual measurement and marking on individual main stiffening plates, resulting in significant errors and inconsistent positioning of the connectors on the two connected bases. This leads to installation difficulties during subsequent assembly and can cause a "stepping" effect, negatively impacting the normal operation and overall stability of the hydraulic support system.

[0003] Therefore, there is an urgent need for an installation method that can accurately position the connecting parts between the split bases and fully ensure their consistency. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a tooling assembly and installation method for installing the base connector of a hydraulic support, which solves the technical problems of poor consistency in the installation position of the connector between the two bases during the assembly of traditional split bases, which easily leads to installation difficulties and the phenomenon of "stepping" back and forth during subsequent use.

[0006] (2) Technical solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] On one hand, the present invention provides a tooling assembly for installing a base connector of a hydraulic support, for installing a bridge plate connector and a bridge plate lug on the main stiffening plates on opposite sides of two bases in a split base. The tooling assembly includes auxiliary drilling tooling and positioning assembly tooling.

[0009] The auxiliary drilling fixture is a plate with a first hole, a second hole, and a third hole, and it has a first side and a second side. The first side and the second side are perpendicular to each other and parallel to the thickness direction of the auxiliary drilling fixture. The dimensions of the first hole, the second hole, and the third hole, and their positional relationship to the first side and the second side, are the same as the dimensions of the column recess positioning hole, the bridge plate connecting seat positioning hole, and the bridge plate ear seat positioning hole on the main stiffening plate, and their positional relationship to the bottom surface and the front surface of the main stiffening plate.

[0010] The positioning assembly fixture includes a first positioning shaft, a second positioning shaft, and a transverse positioning shaft. One end of the first positioning shaft can pass through the positioning hole of the bridge plate connecting seat, and the other end can abut against the U-shaped groove of the bridge plate connecting seat; one end of the second positioning shaft can pass through the positioning hole of the bridge plate ear seat, and the other end can abut against the two ear plates of the bridge plate ear seat; the transverse positioning shaft can pass through both the first mounting hole and the second mounting hole on the side wall of the bridge plate connecting seat.

[0011] Optionally, drill bushings are embedded in the first, second, and third holes, and the inner diameters of the drill bushings in the first, second, and third holes correspond to the dimensions of the column socket positioning hole, the bridge plate connecting seat positioning hole, and the bridge plate ear seat positioning hole, respectively.

[0012] Optionally, the auxiliary drilling tooling also includes a third side opposite to the first side and a fourth side opposite to the second side. The length of the second side is the same as the vertical distance from the top of the front end face of the main stiffener to the bottom surface, and its length is less than the length of the fourth side. The third side includes a first straight edge perpendicularly connected to the second side, a second straight edge perpendicularly connected to the fourth side, and a chamfered section that transitions between the first and second straight edges.

[0013] Optionally, the first positioning shaft is a stepped shaft including a first small shaft segment and a first large shaft segment, wherein the outer diameter of the first small shaft segment is adapted to the inner hole size of the positioning hole of the bridge plate connecting seat, and the outer diameter of the first large shaft segment is adapted to the size of the U-shaped groove.

[0014] Optionally, the second positioning shaft is a stepped shaft including a second small shaft segment and a second large shaft segment, wherein the outer diameter of the second small shaft segment is adapted to the inner hole size of the positioning hole of the bridge plate ear seat, and the outer diameter of the second large shaft segment is adapted to the distance between the two ear plates of the bridge plate ear seat.

[0015] Optionally, the transverse positioning axis is an optical axis, the outer diameter of which is adapted to the inner diameter of the first mounting hole and the second mounting hole.

[0016] On the other hand, the present invention provides a method for installing the base connector of a hydraulic support, wherein the bridge plate connector and the bridge plate ear are installed on the main stiffening plate using any of the above-mentioned tooling.

[0017] Includes the following steps:

[0018] S1: Based on the preset installation positions of the bridge plate connecting seat and the bridge plate ear seat on the main stiffening plate, add corresponding bridge plate connecting seat positioning holes and bridge plate ear seat positioning holes to the original design drawing of the main stiffening plate, and obtain corresponding auxiliary drilling tools and positioning assembly tools.

[0019] S2: Based on the size and position of each hole in the auxiliary drilling tool, the column socket positioning hole, the bridge plate connecting seat positioning hole and the bridge plate ear seat positioning hole are machined on the main stiffening plate.

[0020] S3: Place the main stiffener plate horizontally with the side of the bridge plate connecting seat and the bridge plate ear seat facing upwards;

[0021] S4: Based on the positioning and assembly tooling, the first positioning axis, the second positioning axis and the transverse positioning axis are used to limit and fix the bridge plate connecting seat and the bridge plate ear seat.

[0022] Optionally, in step S2, the first and second sides of the auxiliary drilling tool are aligned with the bottom surface and the front surface, respectively, and the plate surface is attached to the main stiffening plate. The main stiffening plate is then processed based on the size and position of the first hole, the second hole, and the third hole.

[0023] Optionally, step S4 includes the following sub-steps:

[0024] S41: Insert one end of the first positioning shaft and one end of the second positioning shaft into the positioning hole of the bridge plate connecting seat and the positioning hole of the bridge plate ear seat, respectively;

[0025] S42: Place the U-shaped groove opening of the bridge plate connecting seat upward against the other end of the first positioning shaft, and place the two ear plates of the bridge plate ear seat on both sides of the other end of the second positioning shaft.

[0026] S43: The transverse positioning shaft is sequentially inserted into the first mounting hole on the side wall of the bridge plate connecting seat and the second mounting hole on the side wall of the bridge plate ear seat;

[0027] S44: Based on the limiting of the positioning assembly tooling, fix the bridge plate connecting seat and the bridge plate ear seat on the main stiffener plate, and remove the positioning assembly tooling.

[0028] Optionally, in step S4, the bridge plate connecting seat and the bridge plate ear seat are fixedly installed by welding.

[0029] (III) Beneficial Effects

[0030] The beneficial effects of this invention are:

[0031] The present invention provides a tooling assembly and installation method for installing a base connector of a hydraulic support. On one hand, it provides a tooling assembly including an auxiliary drilling tooling and a positioning assembly tooling. The auxiliary drilling tooling has three holes of the same size and position as the column recess positioning hole, the bridge plate connecting seat positioning hole, and the bridge plate ear seat positioning hole on the main stiffening plate, which can quickly locate the position and size of the hole to be drilled on the main stiffening plate. The positioning assembly tooling can simultaneously pass through the bridge plate connecting seat and the bridge plate ear seat and fix their positional relationship to achieve fast and accurate positioning.

[0032] On the other hand, based on the above-mentioned tooling, an installation method is provided. First, positioning holes for the bridge plate connecting seat and the bridge plate ear seat are added to the original design drawing of the main stiffener plate to provide positioning reference for the bridge plate connecting seat and the bridge plate ear seat. Using auxiliary drilling tooling, the column recess positioning hole and the two newly added positioning holes are machined simultaneously on the same reference surface. Then, positioning assembly tooling is used to position and install the bridge plate connecting seat and the bridge plate ear seat, thereby improving the assembly accuracy, better ensuring the consistency of each connecting part between the bases, avoiding subsequent installation difficulties or the phenomenon of the assembled base "stepping" back and forth when working, and thus ensuring the normal operation and overall stability of the entire hydraulic support.

[0050] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "up," "down," "left," and "right" are used interchangeably. Figure 1 The orientation is used as a reference.

[0051] This invention proposes a tooling assembly and installation method for the base connector of a hydraulic support. On one hand, it provides a tooling assembly including an auxiliary drilling tooling and a positioning assembly tooling. The auxiliary drilling tooling has three holes of the same size and position as the column recess positioning hole, the bridge plate connecting seat positioning hole, and the bridge plate ear seat positioning hole on the main stiffening plate, which can quickly locate the position and size of the hole to be drilled on the main stiffening plate. The positioning assembly tooling can simultaneously pass through the bridge plate connecting seat and the bridge plate ear seat and fix their positional relationship to achieve fast and accurate positioning.

[0052] On the other hand, based on the above-mentioned tooling, an installation method is provided. First, positioning holes for the bridge plate connecting seat and the bridge plate ear seat are added to the original design drawing of the main stiffener plate to provide positioning reference for the bridge plate connecting seat and the bridge plate ear seat. Using auxiliary drilling tooling, the column recess positioning hole and the two newly added positioning holes are machined simultaneously on the same reference surface. Then, positioning assembly tooling is used to position and install the bridge plate connecting seat and the bridge plate ear seat, thereby improving the assembly accuracy, better ensuring the consistency of each connecting part between the bases, avoiding subsequent installation difficulties or the phenomenon of the assembled base "stepping" back and forth when working, and thus ensuring the normal operation and overall stability of the entire hydraulic support.

[0053] 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.

[0054] Example 1:

[0055] Reference Figure 1 This diagram shows the structure of the split base of a hydraulic support, which is formed by connecting the left base 10 and the right base 20 via a bridge plate 30. The split base is a crucial component of the entire hydraulic support, its main function being to transfer the pressure from the top plate of the working surface to the bottom plate and to balance the interactions between other components. The consistency of the connections between the two bases is a prerequisite for the normal operation of the split base. Therefore, ensuring the assembly precision of the bridge plate connecting seat 4 and bridge plate ear seat 5 on the main stiffening plates 3 on opposite sides of the two bases is particularly important.

[0056] Reference Figures 2 to 5 This embodiment proposes a tooling assembly for installing a base connector of a hydraulic support, which is used to install a bridge plate connector 4 and a bridge plate lug 5 on the main stiffening plates 3 on opposite sides of the two bases in a split base. The assembly includes an auxiliary drilling tooling 1 and a positioning and assembly tooling 2.

[0057] Auxiliary drilling tool 1, such as Figure 2As shown, it is a plate with a first hole 11, a second hole 12, and a third hole 13, and it has a first side 14, a second side 15, a third side 16, and a fourth side 17. The first side 14 and the third side 16 are arranged opposite each other, and the second side 15 and the fourth side 17 are arranged opposite each other. The first side 14 and the second side 15 are perpendicular to each other and parallel to the thickness direction of the auxiliary drilling tool 1. The length of the second side 15 is the same as the distance from the top of the front end face 35 of the main stiffening plate 3 to the bottom face 34, and its length is less than that of the fourth side 17. The third side 16 includes a first straight edge 161 perpendicularly connected to the second side 15, a second side 162 perpendicularly connected to the fourth side 17, and a chamfered segment 163 that transitions between the first straight edge 161 and the second straight edge 162. In this embodiment, the third side 16 is specifically composed of the first straight edge 161, the chamfered segment 163, and the second straight edge 162 connected end to end, with the chamfered segment 163 connecting between the first straight edge 161 and the second straight edge 162 to form a transition. The dimensions of the first hole 11 and its positional relationship to the first side 14 and the second side 15 (i.e., the vertical distance from the first hole 11 to the first side 14 and the horizontal distance to the second side 15) are the same as the dimensions of the column recess positioning hole 31 on the main stiffening plate 3 and its positional relationship to the lower bottom surface 34 and the front end surface 35 of the main stiffening plate 3 (i.e., the vertical distance from the column recess positioning hole 31 to the lower bottom surface 34 and the horizontal distance to the front end surface 35); the dimensions of the second hole 12 and its positional relationship to the first side 14 and the second side 15 (i.e., the vertical distance from the second hole 12 to the first side 14 and the horizontal distance to the second side 15) are the same as the bridging on the main stiffening plate 3. The dimensions of the plate connecting seat positioning hole 32 and its positional relationship to the lower bottom surface 34 and front end surface 35 of the main stiffening plate 3 (i.e., the vertical distance from the bridge plate connecting seat positioning hole 32 to the lower bottom surface 34 and its horizontal distance to the front end surface 35); the dimensions of the third hole 13 and its positional relationship to the first side 14 and the second side 15 (i.e., the vertical distance from the third hole 13 to the first side 14 and its horizontal distance to the second side 15) are the same as the dimensions of the bridge plate ear seat positioning hole 33 on the main stiffening plate 3 and its positional relationship to the lower bottom surface 34 and front end surface 35 of the main stiffening plate 3 (i.e., the vertical distance from the bridge plate ear seat positioning hole 33 to the lower bottom surface 34 and its horizontal distance to the front end surface 35).Of course, it is not limited to this. Those skilled in the art can set the shape of the auxiliary drilling tool 1 according to actual needs. It is only necessary to ensure that it has corresponding holes that are adapted to the required drilling positions on the main stiffening plate 3, and two perpendicular sides that correspond to the bottom surface 34 and the front surface 35 on the main stiffening plate 3. In this embodiment, the length of the second side 15 is set to be the same as the distance from the top of the front surface 35 of the main stiffening plate 3 to the bottom surface 34, and its length is less than that of the fourth side 17. The third side 16 is perpendicularly connected to the second side 15 and the fourth side 17 on both sides. All of these are to make the shape of the auxiliary drilling tool 1 closer to the shape of the main stiffening plate 3, so that it is easy to find the correct direction and facilitate operation when using it.

[0058] In this embodiment, drill sleeves 18 are embedded in the first hole 11, the second hole 12, and the third hole 13 of the auxiliary drilling tool 1. The inner holes of the drill sleeves 18 in the first hole 11, the second hole 12, and the third hole 13 correspond to the same size as the column socket positioning hole 31, the bridge plate connecting seat positioning hole 32, and the bridge plate ear seat positioning hole 33, respectively. At the same time, the material of the drill sleeves 18 is different from the main body material of the auxiliary drilling tool 1. It can be made of a wear-resistant metal material with higher hardness. Therefore, the damage of the drill bit to the auxiliary drilling tool 1 can be reduced when processing the main stiffening plate 3, so as to ensure the service life of the auxiliary drilling tool 1.

[0059] The auxiliary drilling tool 1 can simultaneously and quickly locate the positions of three holes: the column socket positioning hole 31, the bridge plate connecting seat positioning hole 32, and the bridge plate ear seat positioning hole 33. Compared with the positioning method of manually measuring and marking each hole one by one, it is more accurate and more efficient, providing a positioning reference for the subsequent installation of the bridge plate connecting seat 4 and the bridge plate ear seat 5.

[0060] Positioning assembly tooling 2, such as Figures 3 to 5As shown, the system includes a first positioning shaft 21, a second positioning shaft 22, and a transverse positioning shaft 23. The first positioning shaft 21 is a stepped shaft comprising a first small shaft segment 211 and a first large shaft segment 212. The outer diameter of the first small shaft segment 211 is adapted to the inner diameter of the positioning hole 32 of the bridge plate connecting seat, and the first small shaft segment 211 can pass through the positioning hole 32 of the bridge plate connecting seat. The outer diameter of the first large shaft segment 212 is adapted to the size of the U-shaped groove 42, and the outer peripheral wall of the first large shaft segment 212 can abut against the U-shaped groove 42 of the bridge plate connecting seat 4. The second positioning shaft 22 is also a stepped shaft comprising a second small shaft segment 221 and a second large shaft segment 222. The outer diameter of the second small shaft segment 221 is adapted to the inner diameter of the positioning hole 33 of the bridge plate ear seat, and the second small shaft segment 221 can pass through the positioning hole 33 of the bridge plate ear seat. The outer diameter of the second large shaft segment 222 is adapted to the distance between the two ear plates of the bridge plate ear seat 5, and the outer peripheral wall of the second large shaft segment 222 can abut against the distance between the two ear plates of the bridge plate ear seat 5. The transverse positioning shaft 23 is a smooth shaft, and its outer diameter is adapted to the inner diameter of the first mounting hole 41 on the side wall of the bridge plate connecting seat 4 and the second mounting hole 51 on the side wall of the bridge plate ear seat 5. The transverse positioning shaft 23 can be inserted into both the first mounting hole 41 and the second mounting hole 51. Of course, it is not limited to this. Regarding the shape of the first positioning shaft 21 and the second positioning shaft 22, those skilled in the art can set them according to actual needs. It is not limited to stepped shafts including large shaft segments and small shaft segments. It is only necessary to ensure that one end of each can be inserted into the positioning hole 32 of the bridge plate connecting seat and the positioning hole 33 of the bridge plate ear seat respectively, and the other end can abut against the U-shaped groove 42 and the two ear plates of the bridge plate ear seat 5 respectively.

[0061] The first positioning shaft 21 in the positioning assembly tooling 2 can pass through the positioning hole 32 of the bridge plate connecting seat through the first small shaft section 211, and abut against the U-shaped groove 42 of the bridge plate connecting seat 4 through the first large shaft section, thereby limiting the horizontal and vertical position of the bridge plate connecting seat 4. At this time, the bridge plate connecting seat 4 can only rotate slightly around the axis of the first positioning shaft 21. The second positioning shaft 22 can pass through the positioning hole 33 of the bridge plate ear seat through the second small shaft section 221, and abut against the two ear plates of the bridge plate ear seat 5 through the second large shaft section 222, thereby limiting the horizontal position of the bridge plate ear seat 5. At this time, the bridge plate ear seat 5 can move vertically and can rotate slightly around the axis of the second positioning shaft 22. Furthermore, when inserting the transverse positioning shaft 23, the bridge plate connecting seat 4 needs to be slightly rotated so that the axis of the first mounting hole 41 on its side wall is parallel to the lower bottom surface 34 of the main stiffening plate 3. At the same time, the bridge plate ear seat 5 needs to be moved vertically and slightly rotated so that the second mounting hole 51 on its side wall is aligned with the first mounting hole 41. Only then can the transverse positioning shaft 23 be inserted into both the first mounting hole 41 and the second mounting hole 51 simultaneously. Therefore, as long as the positions of the bridge plate connecting seat positioning hole 32 and the bridge plate ear seat positioning hole 33 are accurate in the early stage, the positions of the bridge plate connecting seat 4 and the bridge plate ear seat 5 can be accurately positioned. Thus, the auxiliary drilling tool 1 and the positioning assembly tool 2 work together to quickly and accurately position the bridge plate connecting seat 4 and the bridge plate ear seat 5 on the main stiffening plate 3, which is very convenient and reliable.

[0062] The above description of the compatibility between various parts of the tooling refers to the inner diameter of the hole or the opening size of the groove being slightly larger than the size of the shaft, so that the mating hole and shaft or groove and shaft can form a clearance fit, which facilitates installation and disassembly.

[0063] Example 2:

[0064] Reference Figure 6 The present embodiment proposes an installation method for the base connector of a hydraulic support, which, based on any of the tooling in Embodiment 1, installs the bridge plate connector 4 and the bridge plate ear 5 on the main stiffener plate 3.

[0065] Specifically, the steps include the following:

[0066] S1: Based on the preset installation positions of the bridge plate connecting seat 4 and the bridge plate ear seat 5 on the main stiffening plate 3, the corresponding bridge plate connecting seat positioning hole 32 and bridge plate ear seat positioning hole 33 are added to the original design drawing of the main stiffening plate 3, and the corresponding auxiliary drilling tool 1 and positioning assembly tool 2 are obtained.

[0067] S2: Based on the size and position of each hole in the auxiliary drilling tool 1, the column socket positioning hole 31, the bridge plate connecting seat positioning hole 32 and the bridge plate ear seat positioning hole 33 are machined on the main stiffening plate 3.

[0068] S3: Place the main stiffening plate 3 horizontally with the side of the bridge plate connecting seat 4 and the bridge plate ear seat 5 facing upwards;

[0069] S4: Based on the positioning and assembly tooling 2, the first positioning shaft 21, the second positioning shaft 22 and the transverse positioning shaft 23 are used to limit and fix the bridge plate connecting seat 4 and the bridge plate ear seat 5.

[0070] This method adds positioning holes 32 and 33 to the bridge plate connecting seat and the bridge plate ear seat in the original design drawing of the main stiffening plate 3. These provide positioning references for the bridge plate connecting seat 4 and the bridge plate ear seat 5. Using auxiliary drilling tool 1, the column recess positioning hole 31 and the two newly added positioning holes are machined simultaneously on the same reference surface. Then, the positioning assembly tool 2 is used to position and install the bridge plate connecting seat 4 and the bridge plate ear seat 5. This improves the assembly accuracy, better ensures the consistency of the connecting parts between the bases, and avoids subsequent installation difficulties or the phenomenon of the assembled base "stepping" back and forth during operation. This ensures the normal operation and overall stability of the entire hydraulic support.

[0071] Each step is discussed in detail below:

[0072] Regarding step S1:

[0073] In this embodiment, as Figure 7 and Figure 8As shown, based on the preset installation positions of the bridge plate connecting seat 4 and the bridge plate ear seat 5 on the main stiffening plate 3, corresponding bridge plate connecting seat positioning holes 32 and bridge plate ear seat positioning holes 33 are added to the original design drawing of the main stiffening plate 3. The positioning hole 32 is located at the center of the bottom of the U-shaped groove 42 when the bridge plate connecting seat 4 is installed, and the positioning hole 33 is located at the center between the two ear plates when the bridge plate ear seat 5 is installed. By adding these two positioning holes, a positioning reference can be provided for the installation of the bridge plate connecting seat 4 and the bridge plate ear seat 5, eliminating the need for manual measurement and marking to determine the position, making the operation more convenient and accurate. Then, the corresponding auxiliary drilling tool 1 and positioning assembly tool 2 are obtained. The required auxiliary drilling tool 1 and positioning assembly tool 2 can be customized according to the dimensions of the preset installation position, or appropriate specifications can be selected from existing auxiliary drilling tool 1 and positioning assembly tool 2. It should be noted that the corresponding auxiliary drilling fixture 1 and positioning assembly fixture 2 mentioned here refer to the following: the dimensions of the first hole 11, the second hole 12, and the third hole 13 in the auxiliary drilling fixture 1, and their positional relationship to the first side 14 and the second side 15, are the same as the dimensions of the pre-set column recess positioning hole 31, the bridge plate connecting seat positioning hole 32, and the bridge plate ear seat positioning hole 33 on the main stiffening plate 3, and their positional relationship to the lower bottom surface 34 and the front end surface 35 of the main stiffening plate 3. One end of the first positioning shaft 21 in the positioning assembly fixture 2 can pass through the bridge plate connecting seat positioning hole 32, and the other end can abut against the U-shaped groove 42 of the bridge plate connecting seat 4. One end of the second positioning shaft 22 can pass through the bridge plate ear seat positioning hole 33, and the other end can abut against the two ear plates of the bridge plate ear seat 5. The transverse positioning shaft 23 can be simultaneously installed in the first mounting hole 41 on the side wall of the bridge plate connecting seat 4 and the second mounting hole 51 on the side wall of the bridge plate ear seat 5.

[0074] Regarding step S2:

[0075] In this embodiment, as Figure 9As shown, the first side 14 and the second side 15 of the auxiliary drilling fixture 1 are aligned with the bottom surface 34 and the front surface 35 of the main stiffening plate 3, respectively, and their surfaces are attached to the main stiffening plate 3. Using drilling equipment such as a CNC drilling machine, a column recess positioning hole 31 is machined on the main stiffening plate 3 based on the position and size of the first hole 11 in the auxiliary drilling fixture 1; a bridge plate connecting seat positioning hole 32 is machined on the main stiffening plate 3 based on the position and size of the second hole 12; and a bridge plate ear seat positioning hole 33 is machined on the main stiffening plate 3 based on the position and size of the third hole 13. During machining, the main stiffening plate 3 and the auxiliary drilling fixture 1 need to be fixed simultaneously on the drilling equipment, and the drill bit is guided through the holes on the auxiliary drilling fixture 1 to perform drilling. Simultaneously machining the column socket positioning hole 31 and the two newly added holes (i.e., the bridge plate connecting seat positioning hole 32 and the bridge plate ear seat positioning hole 33) can better ensure the accuracy of the positional relationship between the holes. At the same time, the column socket positioning hole 31 serves as a common reference for the subsequent machining and assembly of multiple components. The two newly added positioning holes are machined with reference to the column socket positioning hole 31 for multiple main stiffening plates, which can also better ensure the consistency of the holes on different main stiffening plates. Furthermore, by using the auxiliary drilling tool 1 for auxiliary machining, the error caused by repeated positioning and alignment during machining is further avoided, which not only improves the machining accuracy but also improves the work efficiency.

[0076] Regarding step S3:

[0077] In this embodiment, based on assembly requirements, the main stiffening plate 3 is placed horizontally with the side of the bridge plate connecting seat 4 and the bridge plate ear seat 5 facing upwards. The mounting surface of the main stiffening plate 3 is parallel to the horizontal plane. When placing the main stiffening plate 3, it can be placed directly on a horizontal ground or on another table surface that is easy to operate.

[0078] Regarding step S4:

[0079] In this embodiment, as Figure 10 As shown, the positioning assembly tool 2 is installed on the main stiffening plate 3, and then the bridge plate connecting seat 4 and the bridge plate ear seat 5 are fixedly installed based on the limiting of the first positioning shaft 21, the second positioning shaft 22 and the transverse positioning shaft 23.

[0080] Specifically, it includes the following sub-steps:

[0081] Step S41: Insert the small shaft segment 211 of the first positioning shaft 21 into the positioning hole 32 of the bridge plate connecting seat. The side wall of the large shaft segment 212 that connects with the small shaft end 211 is in contact with the main stiffening plate 3. The first positioning shaft 21 is limited and fixed by the clearance fit between the outer diameter of the small shaft segment 211 and the inner hole of the bridge plate connecting seat positioning hole 32. Insert the small shaft segment 221 of the second positioning shaft 22 into the positioning hole 33 of the bridge plate ear seat. The side wall of the large shaft segment 222 that connects with the small shaft segment 221 is in contact with the main stiffening plate 3. The second positioning shaft 22 is limited and fixed by the clearance fit between the outer diameter of the small shaft segment 221 and the inner hole of the bridge plate ear seat positioning hole 33. At this time, both the first positioning shaft 21 and the second positioning shaft 22 are oriented perpendicular to the plate surface of the main stiffening plate 3.

[0082] Step S42: Place the U-shaped groove 42 of the bridge plate connecting seat 4 with its opening facing upward against the main shaft section 212 of the first positioning shaft 21. The inner peripheral wall of the bottom of the U-shaped groove 42 is in contact with the outer peripheral wall of the main shaft section 212. Place the two ear plates of the bridge plate ear seat 5 on both sides of the main shaft section 222 of the second positioning shaft 22, with the inner side wall of the ear plate in contact with the outer wall of the main shaft section 222.

[0083] Step S43: Place the transverse positioning shaft 23 horizontally and insert it sequentially into the first mounting hole 41 on the side wall of the bridge plate connecting seat 4 and the second mounting hole 51 on the side wall of the bridge plate ear seat 5. The positions of the first positioning shaft 21 and the second positioning shaft 22 remain fixed, thus restricting the lateral displacement of the bridge plate connecting seat 4 and the bridge plate ear seat 5. The bottom of the U-shaped groove 42 of the bridge plate connecting seat 4 is in contact with the outer wall of the large shaft section 212 of the first positioning shaft 21, thereby restricting the vertical displacement of the bridge plate connecting seat 4. Then, insert the transverse positioning shaft 23 horizontally into the first mounting hole 41 on the side wall of the bridge plate connecting seat 4, and then adjust the angle of the bridge plate ear seat 5 so that the second mounting hole 51 on its side wall can allow the transverse positioning shaft 23 to pass through. At this time, the positions of the bridge plate connecting seat 4 and the bridge plate ear seat 5 are fixed.

[0084] Step S44: Based on the limiting of the first positioning shaft 21, the second positioning shaft 22 and the transverse positioning shaft 23 in the positioning assembly tooling 2, the bridge plate connecting seat 4 and the bridge plate ear seat 5 are fixedly installed on the main stiffening plate 3 by welding. After the installation is completed, the positioning assembly tooling 2 is removed.

[0085] The positioning assembly tool 2 is used to assist in the installation of the bridge plate connecting seat 4 and the bridge plate ear seat 5. By passing a transverse positioning shaft 23 between the two, the coaxiality of the two parts is ensured. In addition, the trapezoidal positioning shaft is used for double limiting, which ensures the relative positional relationship between the bridge plate connecting seat 4 and the bridge plate ear seat 5. At the same time, it avoids the errors of manual measurement and scribing, and improves work efficiency.

[0086] In this embodiment, by adding a bridge plate connecting seat positioning hole 32 and a bridge plate ear seat positioning hole 33 to the main stiffening plate 3, and using the auxiliary drilling tool 1 and the positioning assembly tool 2 in the tooling to perform drilling and assembly positioning, the bridge plate connecting seat 4 and the bridge plate ear seat 5 can be installed on the main stiffening plate 3 quickly and accurately. This is very convenient and reliable. In the process of mass production, it can greatly improve work efficiency while ensuring assembly accuracy.
