Description

Technical Field

[0001] This invention relates to the field of welding tool technology, specifically to a multi-station hinged reinforcing plate welding fixture and its positioning method. Background Technology

[0002] In traditional automotive seat bracket manufacturing processes, the flat plate structure before welding often suffers from surface flatness issues due to initial stamping errors, material internal stress, or deformation during transport and clamping. Directly using this flat plate for welding leads to poor fit between workpieces, resulting in defects such as porosity and incomplete welds, thus affecting the structural strength of the bracket. Furthermore, the lack of a secondary stamping process for the flat plate structure before welding, or the need for manual handling of workpieces to independent stamping equipment for correction, not only increases process time but may also introduce new positioning errors due to multiple clamping operations, resulting in unsatisfactory flatness even after welding. Additionally, in the automotive seat bracket manufacturing field, traditional processes typically separate stamping and welding operations, requiring multiple workpiece clamping and equipment transfers. This leads to long production cycles, cumbersome processes, and difficulty in meeting the demands of large-scale production.

[0003] Existing technologies offer numerous solutions to the problem of separation between stamping and welding during workpiece processing. For example, prior art CN104889691B discloses a stamping and welding production line, which includes a feeding mechanism, a cutting and transposing mechanism, a stamping inspection mechanism, a clamping and inspection mechanism, a welding mechanism, a welding inspection mechanism, a main electrical control cabinet, and area sensors, all installed on the factory floor. This invention achieves high stamping and welding efficiency and good production stability. Another example is prior art US17797251, which discloses a flexible assembly system comprising at least one manufacturing unit. This manufacturing unit includes at least one general-purpose fixture, at least one position monitoring device, and at least one programmable robot or machine (e.g., punching, welding, etc.). The at least one general-purpose fixture is non-dedicated, allowing it to be used for various products rather than being specific to a single manufactured part. However, the aforementioned prior art still has room for improvement in terms of pre-processing of welded stamped workpieces and integration of welding and stamping equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-station seat bracket stamping-welding integrated production equipment. By integrating the stamping machine and welding components, it solves the problems of low production efficiency, insufficient positioning accuracy, vibration and noise caused by the separation of stamping and welding processes in traditional production processes.

[0005] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0006] A multi-station integrated stamping and welding production line for seat brackets includes a frame, on which welding components and a stamping machine are mounted. Both the welding components and the stamping machine have base plates at their bottoms. This invention allows the welding components and the stamping machine to be mounted on the frame as needed via the base plates. This integrates the traditionally separate stamping and welding processes into a single device. The structural support of the base plates avoids the need for workpiece transfer and multiple clamping operations between different devices, shortening the production cycle and improving the efficiency of large-scale production.

[0007] According to one embodiment of the present invention, a first limiting block is provided on the upper part of the base plate of the welding assembly. The first limiting block has a slot that allows one end of a second workpiece to be inserted. A first drive motor is provided on one side of the first limiting block, which can be assembled with the second workpiece and drive the second workpiece to rotate. The slot of the first limiting block of the present invention can accurately engage the end of the second workpiece, forming a two-end positioning structure with the second limiting block on the base plate. This enables multi-dimensional limiting and ensures accurate positioning. Furthermore, after the first drive motor is assembled with the second workpiece, it can synchronously drive the second workpiece to rotate, realizing automated control of circumferential welding or multi-angle welding processes, and avoiding defects such as weld point offset and incomplete welding caused by angular deviation.

[0008] According to one embodiment of the present invention, a second limiting block is mounted on the base plate of the welding assembly via a support plate. The second limiting block is spaced apart from the first limiting block. The second limiting block has a slot that allows the other end of a second workpiece to be inserted. A placement plate is provided on the side of the second limiting block, and a first workpiece that mates with the second workpiece is placed on the placement plate. The second limiting block, mounted on the base plate of the welding assembly via a support plate and spaced apart from the first limiting block, has a slot that can hold the other end of the second workpiece, forming a two-end positioning structure with the first limiting block. This achieves multi-dimensional precise positioning of the second workpiece, effectively preventing workpiece displacement during welding, ensuring the accuracy of the welding position, and solving the problem of workpiece skew caused by traditional single-end positioning. At the same time, the placement plate on the side of the second limiting block provides a first workpiece that mates with the second workpiece, enabling pre-positioning assembly of the two workpieces. This facilitates subsequent precise welding operations by a second robotic arm, reducing workpiece clamping time and positioning errors, and improving the continuity and production efficiency of the welding process. Furthermore, by driving the second workpiece, rotation or arbitrary angle positioning can be achieved, adapting to process requirements such as circumferential welding and multi-angle lap welding. When welding the annular ribs of an automotive seat bracket, the uniformity of the weld spacing can be controlled by programming and setting the linkage parameters between the motor speed and the moving speed of the welding robot. Through the cooperation of the first drive motor and the first and second limit blocks, the workpiece clamping time can be shortened.

[0009] According to one embodiment of the present invention, a second robotic arm is provided on the frame for welding a first workpiece and a second workpiece. The second robotic arm on the frame, used for welding the first and second workpieces, employs a six-axis linkage control structure, enabling flexible adjustment of the welding angle and position in three-dimensional space to adapt to the welding requirements of complex welds in seat brackets. This robotic arm supports offline programming and online debugging, and can quickly switch welding processes for different models of seat brackets.

[0010] According to one embodiment of the present invention, both the welding assembly and the bottom plate of the stamping machine are connected to the frame via a vibration isolation assembly. The vibration isolation assembly includes a first vibration isolation plate and a second vibration isolation plate arranged horizontally, and the edges of the first vibration isolation plate and the second vibration isolation plate are connected by an inclined damping support rod.

[0011] This invention achieves vibration isolation in both horizontal and vertical directions through inclined damping support rods. Specifically, the shear deformation of the damping material dissipates vibration energy, attenuating the impact vibration generated during the operation of the stamping press. Vibration during welding assembly operation can also be controlled. The double-layer structure of the first and second vibration isolation plates blocks the vibration transmission path. Combined with the nonlinear vibration reduction characteristics of the damping support rods, the overall operating noise of the equipment is reduced, meeting industrial noise reduction standards. Furthermore, the energy-absorbing components in the vibration isolation assembly absorb the impact energy generated during the operation of the stamping press through elastic deformation and damping, reducing fatigue damage to the frame, base plate, and internal mechanical components.

[0012] According to one embodiment of the present invention, energy-absorbing elements are evenly distributed between the first and second vibration isolation plates. Each energy-absorbing element has a first energy-absorbing substrate and a second energy-absorbing substrate spaced vertically apart. A first damping element is arranged around the bottom surface of the second energy-absorbing substrate, and a second damping element is arranged around the surface of the first energy-absorbing substrate relative to the surface of the second energy-absorbing substrate. The second damping element and the first damping element are offset from each other, and a first spring connects them. The energy-absorbing elements evenly distributed between the first and second vibration isolation plates, through the vertically spaced first and second energy-absorbing substrates, can form a double-layer elastic buffer. The first damping element surrounding the bottom surface of the second energy-absorbing substrate and the second damping element surrounding the surface of the first energy-absorbing substrate are offset from each other and connected by the first spring, constituting an energy absorption method combining a spring and a damping element. When the press or welding assembly vibrates, the first spring impacts the energy through elastic deformation, and the offset first and second damping elements consume vibration energy of different frequencies through shear deformation. The rubber damping on the sides of the first and second energy-absorbing substrates further blocks the vibration transmission path, controlling the vertical vibration amplitude and horizontal vibration of the base plate within a small range.

[0013] The first damper is spaced apart from the surface of the first energy-absorbing substrate, and the second damper is spaced apart from the surface of the second energy-absorbing substrate. The number of first and second dampers is the same. The second energy-absorbing substrate is connected to the first damper by fasteners, and the first energy-absorbing substrate is connected to the second damper by fasteners. Both the first and second energy-absorbing substrates have connecting posts on their sides that connect to adjacent first and second vibration isolation plates.

[0014] When the equipment vibrates, the gap between the first and second dampers and the adjacent energy-absorbing substrates allows the first and second dampers to undergo lateral shear deformation. Combined with a symmetrical layout of equal numbers, it can simultaneously absorb vibration energy in both horizontal and vertical directions. Furthermore, the use of fasteners to connect the dampers shortens the disassembly and assembly time of individual energy-absorbing components, making it easier to replace worn damping units as needed. In addition, the connecting posts on the sides of the first and second energy-absorbing substrates are rigidly connected to the first and second vibration isolation plates through an adhesive process, forming an annular sealed vibration isolation strip, which can block the transmission path of high-frequency vibration and reduce equipment operating noise.

[0015] According to one embodiment of the present invention, the base plate of the welding assembly has a mounting block, and the mounting block has a first limiting plate. The plane of the first limiting plate is perpendicular to the second workpiece, and the first limiting plate has a groove that can abut against the side of the second workpiece. The groove in the present invention adopts a U-shaped structure adapted to the contour of the side of the second workpiece, which can closely fit the side of the workpiece. By positioning the two ends of the first and second limiting blocks, a three-dimensional limiting method can be formed at both ends and the side, so that the X / Y / Z axis displacement deviation of the second workpiece during the welding process can be controlled. The rigid connection between the mounting block and the base plate can ensure that the perpendicularity deviation of the first limiting plate is reduced, and its arrangement perpendicular to the workpiece can effectively limit the lateral swing of the second workpiece. When welding the L-shaped fillet weld of the seat bracket, the abutment positioning of the groove with the side of the second workpiece can keep the distance deviation between the welding torch and the weld within a controllable range. In addition, by changing the first limiting plate with different groove specifications, the production needs of various models of seat brackets can be quickly adapted.

[0016] According to one embodiment of the present invention, the second workpiece also has two opposingly arranged second limiting plates on its two sides. The sides of the second limiting plates abut against the sides of the second workpiece, and the second limiting plates are connected to the mounting block via a first connecting bracket. The sides of the second limiting plates have anti-slip textures, and the surface of the second limiting plates abuts tightly against the sides of the second workpiece. Combined with the groove positioning of the first limiting plate, this forms a four-way constraint in the front-back and sides, ensuring that the lateral offset of the second workpiece during welding is within a controllable range. The first connecting bracket adopts an adjustable bolt connection structure, which can flexibly adjust the distance between the two second limiting plates according to the width of the second workpiece. Furthermore, when welding the side plate of the seat bracket, the two second limiting plates can simultaneously counteract the lateral stress generated by welding heat deformation, reducing the flatness error of the workpiece after welding.

[0017] According to one embodiment of the present invention, a first robotic arm is provided on the frame. The first robotic arm is used to clamp a first workpiece and a second workpiece. After the first workpiece is processed in the stamping press, it is clamped by the first robotic arm and placed on a placement plate on the side of a second limiting block. The placement plate has a positioning groove or positioning rod adapted to the first workpiece. The first robotic arm installed on the frame can realize the automated clamping and transfer of the first and second workpieces. After the first workpiece has completed its shaping process in the stamping press, the first robotic arm stably grasps the workpiece and moves it along a preset trajectory to the top of the placement plate. Secondary positioning is achieved by using the positioning groove or positioning rod adapted to the first workpiece on the placement plate to ensure the flatness of the workpiece when it is placed.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Example 1:

[0031] As shown in the attached figure Figure 1 - Appendix Figure 8As shown, this invention provides a multi-station integrated stamping-welding production equipment for seat brackets, including a frame 10. Welding components and a stamping machine 20 are respectively mounted on the frame 10. Both the welding components and the stamping machine 20 have a base plate 50 at their bottom. This invention allows the welding components and the stamping machine 20 to be mounted on the frame 10 as needed via the base plate 50. This integrates the traditionally separate stamping and welding processes into the same equipment. The structural support of the base plate 50 avoids the transfer and multiple clamping of workpieces between different devices, shortening the production cycle and improving the efficiency of large-scale production.

[0032] As shown in the attached figure Figure 2 - Appendix Figure 3 As shown, a first limiting block 53 is provided on the upper part of the base plate of the welding assembly. The first limiting block 53 has a slot that allows one end of the second workpiece 41 to be inserted. A first drive motor 51 is provided on one side of the first limiting block 53, which can be assembled with the second workpiece 41 and drive the second workpiece 41 to rotate. The slot of the first limiting block 53 of the present invention can accurately engage the end of the second workpiece 41, forming a two-end positioning structure with the second limiting block 58 on the base plate. This can achieve multi-dimensional limiting and ensure accurate positioning. Furthermore, after the first drive motor 51 is assembled with the second workpiece 41, it can synchronously drive the second workpiece 41 to rotate, realizing the automated control of circumferential welding or multi-angle welding processes, and avoiding defects such as weld point offset and incomplete welding caused by angular deviation.

[0033] As shown in the attached figure Figure 4 - Appendix Figure 5As shown, a second limiting block 58 is mounted on the base plate of the welding assembly via a support plate. The second limiting block 58 is spaced apart from the first limiting block 53. The second limiting block 58 has a slot that allows the other end of the second workpiece 41 to be inserted. A placement plate is located on the side of the second limiting block 58, and a first workpiece 40 that mates with the second workpiece 41 is located on the placement plate. The second limiting block 58, which is spaced apart from the first limiting block 53, is mounted on the base plate of the welding assembly via a support plate. The slot can hold the other end of the second workpiece 41, forming a two-end positioning structure with the first limiting block 53. This achieves multi-dimensional precise positioning of the second workpiece 41, effectively preventing workpiece displacement during welding, ensuring the accuracy of the welding position, and solving the problem of workpiece skew caused by traditional single-end positioning. At the same time, the placement plate on the side of the second limiting block 58 has a first workpiece 40 that mates with the second workpiece 41, which can realize the pre-positioning assembly of the two workpieces. This facilitates the subsequent precise operation of the welding position by the second robot arm 13, reduces workpiece clamping time and positioning errors, and improves the continuity and production efficiency of the welding process. Furthermore, by driving the second workpiece 41, rotation or arbitrary angle positioning can be achieved, adapting to process requirements such as circumferential welding and multi-angle lap welding. When welding the annular ribs of an automotive seat bracket, the uniformity of the weld spacing can be controlled by programming and setting the linkage parameters between the motor speed and the moving speed of the welding robot. Through the cooperation of the first drive motor 51 and the first and second limit blocks, the workpiece clamping time can be shortened.

[0034] The frame 10 has a second robotic arm 13 for welding the first workpiece 40 and the second workpiece 41. The welding assembly and the base plate 50 at the bottom of the stamping machine 20 are connected to the frame 10 via a vibration isolation assembly 30. The vibration isolation assembly 30 includes a first vibration isolation plate 31 and a second vibration isolation plate 34 arranged horizontally, with their edges connected by inclined damping support rods. The second robotic arm 13 on the frame 10, used for welding the first workpiece 40 and the second workpiece 41, employs a six-axis linkage control structure, allowing for flexible adjustment of the welding angle and position in three-dimensional space, adapting to the welding requirements of complex weld seams in seat brackets. This robotic arm supports offline programming and online debugging, and can quickly switch between welding processes for different models of seat brackets.

[0035] This invention achieves vibration isolation in both horizontal and vertical directions through inclined damping support rods. Specifically, the shear deformation of the damping material dissipates vibration energy, attenuating the impact vibration generated during the operation of the press 20. Vibration during welding assembly operation can also be controlled. The double-layer structure of the first and second vibration isolation plates 31 and 34 blocks the vibration transmission path. Combined with the nonlinear vibration reduction characteristics of the damping support rods, the overall operating noise of the equipment is reduced, meeting industrial noise reduction standards. Furthermore, the energy-absorbing component 33 in the vibration isolation assembly absorbs the impact energy generated during the operation of the press 20 through elastic deformation and damping, reducing fatigue damage to the frame 10, base plate 50, and internal mechanical components.

[0036] See appendix Figure 6-8 As shown, energy-absorbing elements 33 are evenly distributed between the first vibration isolation plate 31 and the second vibration isolation plate 34. Each energy-absorbing element 33 has a first energy-absorbing substrate 331 and a second energy-absorbing substrate 332 arranged vertically at intervals. A first damping element 36 is arranged around the bottom surface of the second energy-absorbing substrate 332, and a second damping element 37 is arranged around the surface of the first energy-absorbing substrate 331 relative to the surface of the second energy-absorbing substrate 332. The second damping element 37 and the first damping element 36 are offset from each other, and a first spring 35 connects them. The energy-absorbing elements 33 evenly distributed between the first vibration isolation plate 31 and the second vibration isolation plate 34, through the vertically spaced first energy-absorbing substrate 331 and the second energy-absorbing substrate 332, can form a double-layer elastic buffer. The first damping element 36 surrounding the bottom surface of the second energy-absorbing substrate 332 and the second damping element 37 surrounding the surface of the first energy-absorbing substrate 331 are offset from each other and connected by the first spring 35, forming a combination of spring and damping for energy absorption. When the stamping machine 20 or the welding assembly vibrates, the first spring 35 impacts the energy through elastic deformation, and the first damper 36 and the second damper 37, which are misaligned, consume the vibration energy of different frequencies through shear deformation. The rubber dampers on the sides of the first energy-absorbing substrate 331 and the second energy-absorbing substrate 332 further block the vibration transmission path, controlling the vertical vibration amplitude and horizontal vibration of the base plate 50 within a small range.

[0037] The first damper 36 is spaced apart from the surface of the first energy-absorbing substrate 331, and the second damper 37 is spaced apart from the surface of the second energy-absorbing substrate 332. The number of first dampers 36 and second dampers 37 is the same. The second energy-absorbing substrate 332 is connected to the first damper 36 by fasteners, and the first energy-absorbing substrate 331 is connected to the second damper 37 by fasteners. Both the first energy-absorbing substrate 331 and the second energy-absorbing substrate 332 have connecting posts on their sides that connect to the adjacent first vibration isolation plate 31 and second vibration isolation plate 34.

[0038] When the equipment vibrates, the gap between the first and second dampers and the adjacent energy-absorbing substrates allows the first damper 36 and the second damper 37 to undergo lateral shear deformation. With the same number of symmetrical layouts, they can synchronously absorb vibration energy in both horizontal and vertical directions. Furthermore, the use of fasteners to connect the dampers shortens the disassembly and assembly time of a single energy-absorbing component 33, making it easier to replace worn damping units as needed. In addition, the connecting posts on the sides of the first energy-absorbing substrate 331 and the second energy-absorbing substrate 332 are rigidly connected to the first vibration isolation plate 31 and the second vibration isolation plate 34 through an adhesive process, forming an annular sealed vibration isolation strip, which can block the transmission path of high-frequency vibration and reduce the operating noise of the equipment.

[0039] The base plate of the welding assembly has a mounting block, and the mounting block has a first limiting plate 55. The plane of the first limiting plate 55 is perpendicular to the second workpiece 41, and the first limiting plate 55 has a groove that can abut against the side of the second workpiece 41. The groove in this invention adopts a U-shaped structure that adapts to the side profile of the second workpiece 41, which can closely fit the side of the workpiece. Through the positioning of the two ends of the first limiting block 53 and the second limiting block 58, a three-dimensional limiting method can be formed at both ends and the side, so that the X / Y / Z axis displacement deviation of the second workpiece 41 during the welding process can be controlled. The rigid connection between the mounting block and the base plate can ensure that the perpendicularity deviation of the first limiting plate 55 is reduced, and its arrangement perpendicular to the workpiece can effectively limit the lateral swing of the second workpiece 41. When welding the L-shaped fillet weld of the seat bracket, the abutment positioning of the groove with the side of the second workpiece 41 can keep the distance deviation between the welding torch and the weld within a controllable range. In addition, by changing the first limiting plate 55 with different groove specifications, the production needs of various models of seat brackets can be quickly adapted.

[0040] The second workpiece 41 also has two opposing second limiting plates 56 on its sides. The sides of the second limiting plates 56 abut against the sides of the second workpiece 41, and the second limiting plates 56 are connected to the mounting block via the first connecting bracket 54. The sides of the second limiting plates 56 have anti-slip textures, and the surface of the second limiting plates 56 abuts tightly against the sides of the second workpiece 41. Combined with the positioning grooves of the first limiting plates 55, this forms a four-way constraint (front-back and sides), keeping the lateral offset of the second workpiece 41 within a controllable range during welding. The first connecting bracket 54 uses an adjustable bolt connection structure, allowing for flexible adjustment of the distance between the two second limiting plates 56 according to the width of the second workpiece 41. Furthermore, when welding the side panels of the seat bracket, the two second limiting plates 56 can simultaneously counteract the lateral stress generated by welding heat deformation, reducing the flatness error of the workpiece after welding.

[0041] The frame 10 is equipped with a first robotic arm 12. The first robotic arm 12 is used to clamp a first workpiece 40 and a second workpiece 41. After the first workpiece 40 is processed in the stamping machine 20, it is clamped by the first robotic arm 12 and placed on a placement plate on the side of the second limiting block 58. The placement plate has a positioning groove or positioning rod adapted to the first workpiece 40. The first robotic arm 12 installed on the frame 10 can realize the automated clamping and transfer of the first workpiece 40 and the second workpiece 41. After the first workpiece 40 has completed the shaping process in the stamping machine 20, the first robotic arm 12 stably grasps the workpiece and moves it along a preset trajectory to the top of the placement plate. The positioning groove or positioning rod adapted to the first workpiece 40 on the placement plate is used to achieve secondary positioning to ensure the flatness of the workpiece when it is placed.

[0042] Example 2:

[0043] This embodiment is a further optimized version of Embodiment 1, as shown in the appendix. Figure 4 Appendix Figure 5 As shown, a third limiting plate 57 is provided above the slot of the second limiting block 58, capable of displacement relative to the slot of the second limiting block 58. A first hydraulic cylinder 52 is connected to one side of the third limiting plate 57, and the first hydraulic cylinder 52 is connected to a support plate on the bottom plate of the welding assembly. The end face of the third limiting plate 57 relative to the second limiting block 58 has a rubber block, which can abut against the surface of the second workpiece 41 inside the second limiting block 58. The surface of the rubber block has anti-slip texture. When the second workpiece 41 is placed in the slot of the second limiting block 58, the first hydraulic cylinder 52 drives the third limiting plate 57 to move downward, and the rubber block on its end face forms an elastic abutment with the surface of the second workpiece 41. The anti-slip texture of the rubber block, in conjunction with the slot positioning of the second limiting block 58, forms a two-way constraint of upper pressure and lower support, so that the displacement deviation of the second workpiece 41 in the Z-axis direction is within a controllable range.

[0044] Example 3:

[0045] This embodiment is a further optimized version of Embodiment 1, as shown in the appendix. Figure 1 Appendix Figure 4 Appendix Figure 5 As shown, an air gun or nozzle is provided on one side of the welding position between the first workpiece 40 and the second workpiece 41 for cleaning welding residue or spraying cooling media. The functions of cleaning welding residue and spraying cooling media can be automated. After the second robotic arm 13 completes the welding operation, the air gun can remove residual welding slag, spatter, and other impurities from the weld surface, achieving a cleaning efficiency of over 95% and preventing surface defects caused by residue adhesion. The nozzle can spray water-based coolant or antioxidants according to process requirements.

[0046] Example 4:

[0047] This embodiment is a further optimized version of Embodiment 1, as shown in the appendix. Figure 1 As shown, a control box 11 is located on one side of the frame 10. The control box 11 is electrically connected to the electrical equipment on the frame 10 and is used to control the start and stop of each piece of equipment. The control box 11 is equipped with an emergency stop button. The control box 11 located on one side of the frame 10 is electrically connected to electrical equipment such as the stamping machine 20, the first robotic arm 12, and the second robotic arm 13 on the frame 10 to achieve centralized start and stop control of each piece of equipment.

[0048] Example 5:

[0049] This embodiment is a further optimized version of Embodiment 1, as shown in the appendix. Figure 1 As shown,

[0050] The frame 10 has a plate structure arranged in parallel at the top and bottom. The upper and lower plates are connected by support corner plates and the horizontal state of the upper and lower plate structures can be adjusted. In case of changes in the equipment placement environment, the horizontal state of the upper plate of the frame 10 needs to be calibrated by a level.

[0051] The frame 10 adopts a plate structure with parallel upper and lower plates. The upper and lower plates are connected by support corner plates and adjusted for levelness, enabling high-precision calibration of the equipment installation. The inclined surface of the support corner plates forms a stable triangular structure with the upper and lower plates.
