Description

Technical Field

[0001] This utility model belongs to the field of sheet metal parts, specifically relating to a modular adjustable anti-deformation sheet metal part structure. Background Technology

[0002] In the field of sheet metal structure design and manufacturing, multi-plate composite structures are widely used due to their versatility and applicability. However, existing sheet metal composite structures still have the following significant drawbacks: On the one hand, traditional sheet metal connections are mostly rigidly fixed, lacking an effective lateral position adjustment mechanism. During actual assembly or use, factors such as processing errors, thermal deformation, or load variations often lead to deviations in the relative position between the two plates. Existing structures struggle to achieve rapid and precise spacing adjustments, affecting overall assembly accuracy and performance. Even when some structures are equipped with adjustment devices, they often suffer from complex operation, limited adjustment range, or insecure locking.

[0003] On the other hand, existing sheet metal structures have relatively simple designs in terms of deformation resistance and cushioning, usually relying only on rigid supports or simple spring structures, lacking bidirectional cushioning and multi-level deformation prevention capabilities. When subjected to external impacts or vibrations, they are prone to plastic deformation or fatigue damage, affecting structural stability and service life. Especially in high-frequency vibration or temperature change environments, traditional structures are unable to effectively absorb energy and suppress deformation, posing significant safety and reliability risks.

[0004] Therefore, there is an urgent need for a sheet metal structure with flexible adjustment capabilities and efficient buffering and anti-deformation functions to solve the problems of inconvenient adjustment and insufficient anti-deformation capabilities in the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a modular adjustable anti-deformation sheet metal structure that can precisely adjust the lateral spacing between two sheet metal plates to achieve an efficient buffering anti-deformation function.

[0006] The purpose of this utility model is achieved through the following technical solution: a modular adjustable anti-deformation sheet metal structure, including a first sheet metal plate and a second sheet metal plate arranged in parallel at the top and bottom, and a plurality of bidirectional buffer support components placed between the first sheet metal plate and the second sheet metal plate. One side of the first sheet metal plate and the second sheet metal plate has an adjustment connection component, and the other side of the first sheet metal plate and the second sheet metal plate has a buffer connection component. The bidirectional buffer support assembly includes a central guide post that is vertically perpendicular to the first sheet metal plate and the second sheet metal plate. The upper and lower ends of the central guide post are respectively provided with an upper support spring and a lower support spring, which are respectively disposed on the upper surface of the first sheet metal plate and the lower surface of the second sheet metal plate.

[0007] A further improvement of this utility model is that the adjusting connection assembly includes a base, an adjusting slider, and a locking assembly. The base is fixed to the side end of the first sheet metal plate and has a groove. The adjusting slider is slidably disposed in the groove of the base. The side end of the base has a pushing bolt for pushing the adjusting slider to slide in the groove. The pushing bolt is threadedly connected to the base, and the end face of the pushing bolt contacts the adjusting slider. The locking assembly locks the second sheet metal plate onto the adjusting slider.

[0008] A further improvement of this utility model is that the locking assembly includes an adjusting bolt and a clamping block; the clamping block is disposed on the side end of the second sheet metal plate, the adjusting bolt vertically passes through the base and the adjusting slider in sequence and is threadedly connected to the clamping block, the base has a strip-shaped through hole for the adjusting bolt to pass through vertically and move horizontally back and forth, the contact surface between the clamping block and the adjusting slider is provided with anti-slip texture, and the adjusting bolt is placed on the outer end face of the clamping block with a locking nut for locking the clamping block and the adjusting slider.

[0009] A further improvement of this utility model is that: the first sheet metal plate and the second sheet metal plate have two strip-shaped through holes for the central guide post to pass through and for adjusting the lateral spacing between the first sheet metal plate and the second sheet metal plate.

[0010] A further improvement of this utility model is that: the outer surfaces of both the upper and lower ends of the central guide post are provided with external threads; on the threaded section of each end of the central guide post, an adjusting nut and a limiting cap are sequentially fitted outward along the axial direction of the central guide post; the upper support spring is pressed between the upper surface of the first sheet metal plate and the adjusting nut; and the lower support spring is pressed between the lower surface of the second sheet metal plate and the adjusting nut.

[0011] A further improvement of this utility model is that a polyurethane buffer column is coaxially sleeved on the central guide column, the polyurethane buffer column is located between the first sheet metal plate and the second sheet metal plate, and a buffer gap is left between its upper and lower end faces and the two plates.

[0012] A further improvement of this utility model is that the buffer connection assembly includes an E-shaped buffer block that covers the side ends of the first sheet metal plate and the second sheet metal plate, and the outside of the E-shaped buffer block has a metal U-shaped frame with an opening facing the E-shaped buffer block.

[0013] A further improvement of this utility model is that the polyurethane buffer column and the central guide column are interference fit.

[0014] This utility model has the following advantages compared with the prior art: 1. This utility model, through an adjustment connection assembly consisting of a base, an adjusting slider, and a pushing bolt, allows for fine-tuning of the lateral position of the second sheet metal plate relative to the first sheet metal plate. Simply rotating the pushing bolt drives the adjusting slider to slide precisely within the groove, effectively compensating for manufacturing and assembly errors and adapting to spacing requirements under different working conditions. The design of the locking assembly and the strip-shaped through hole allows the second sheet metal plate to be reliably locked to the first sheet metal plate by tightening the adjusting bolt and the locking nut after position adjustment, utilizing the threaded transmission between the clamping block and the adjusting bolt. This effectively prevents loosening and displacement caused by vibration during use, ensuring the long-term stability of the adjusted structure. 2. In this utility model, the upper and lower support springs at both ends of the central guide column of the bidirectional buffer support assembly, and pre-tightened with adjusting nuts, provide bidirectional elastic support for the first and second sheet metal plates respectively. This structure can effectively absorb and disperse impact and vibration energy from different directions, suppressing warping and deformation of the sheet metal plates; the added polyurethane buffer column, as a second buffer line, can contact the plate and provide progressive nonlinear damping when it undergoes large displacement with the sheet metal plate, working in synergy with the springs to greatly enhance the structure's energy absorption capacity and impact resistance. 3. The buffer connection assembly formed by the E-shaped buffer block on the side and the metal U-shaped frame in this utility model not only restricts the lateral relative displacement of the two plates, but its elastic properties can also absorb the lateral impact force. Together with the bidirectional buffer support assembly, it forms a three-dimensional and all-round anti-deformation protection system, which significantly improves the rigidity and stability of the entire sheet metal structure under dynamic load and extends its service life.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can be described as a mechanical connection, a direct connection, or a connection through an intermediate medium. Those skilled in the art can understand the basic meaning of the above terms in this utility model according to the specific circumstances. Example 1

[0022] A modular adjustable anti-deformation sheet metal structure, referring to Figure 1 A modular adjustable anti-deformation sheet metal structure includes a first sheet metal plate 1 and a second sheet metal plate 2 arranged in parallel at the top and bottom, and multiple bidirectional buffer support components 4 placed between the first sheet metal plate 1 and the second sheet metal plate 2. One side of the first sheet metal plate 1 and the second sheet metal plate 2 has an adjustment connection component 3, and the other side of the first sheet metal plate 1 and the second sheet metal plate 2 has a buffer connection component 5. The bidirectional buffer support assembly 4 includes a central guide post 43 that is vertically perpendicular to the first sheet metal plate 1 and the second sheet metal plate 2. The upper and lower ends of the central guide post 43 are respectively provided with an upper support spring 41 and a lower support spring 42, which are respectively disposed on the upper surface of the first sheet metal plate 1 and the lower surface of the second sheet metal plate 2.

[0023] Reference Figure 2The adjusting connection assembly 3 includes a base 31, an adjusting slider 32, and a locking assembly 33. The base 31 is fixed to the side end of the first sheet metal plate 1. The base 31 has a groove 34. The adjusting slider 32 is slidably disposed in the groove 34 of the base 31. The side end of the base 31 has a pushing bolt 35 for pushing the adjusting slider 32 to slide in the groove 34. The pushing bolt 35 is threadedly connected to the base 31, and the end face of the pushing bolt 35 is in contact with the adjusting slider 32. The locking assembly 33 locks the second sheet metal plate 2 onto the adjusting slider 32.

[0024] The locking assembly 33 includes an adjusting bolt 331 and a clamping block 332. The clamping block 332 is located on the side of the second sheet metal plate 2. The adjusting bolt 331 vertically passes through the base 31 and the adjusting slider 32 in sequence and is threadedly connected to the clamping block 332. The base 31 has a strip-shaped through hole 333 through which the adjusting bolt 331 vertically passes and moves horizontally back and forth. The contact surface between the clamping block 332 and the adjusting slider 32 is provided with anti-slip texture. The outer end face of the adjusting bolt 331, located on the clamping block 332, has a locking nut 334 that locks the clamping block 332 and the adjusting slider 32.

[0025] This utility model utilizes an adjustment connection assembly 3, consisting of a base 31, an adjusting slider 32, and a pushing bolt 35, to finely adjust the lateral position of the second sheet metal plate 2 relative to the first sheet metal plate 1. Simply rotating the pushing bolt 35 drives the adjusting slider 32 to slide precisely within the groove 34, effectively compensating for manufacturing and assembly errors and adapting to spacing requirements under different working conditions. The locking assembly 33 and the slotted through-hole 333's design ensure that after position adjustment, tightening the adjusting bolt 331 and the locking nut 334 reliably locks the second sheet metal plate 2 and the first sheet metal plate 1 using the threaded transmission of the clamping block 332 and the adjusting bolt 331. This effectively prevents loosening and displacement caused by vibration during use, ensuring the long-term stability of the adjusted structure. Example 2

[0026] Based on Example 1, referring to Figure 3 The first sheet metal plate 1 and the second sheet metal plate 2 have a strip-shaped through hole 44 through which the central guide post 43 passes and allows for lateral spacing adjustment of the first sheet metal plate 1 and the second sheet metal plate 2.

[0027] The outer surfaces of both the upper and lower ends of the central guide post 43 are provided with external threads. On the threaded section of each end of the central guide post 43, an adjusting nut 45 and a limiting cap 46 are sequentially fitted outward along the axial direction of the central guide post 43. The upper support spring 41 is pressed between the upper surface of the first sheet metal plate 1 and the adjusting nut 45, and the lower support spring 42 is pressed between the lower surface of the second sheet metal plate 2 and the adjusting nut 45.

[0028] In this invention, the bidirectional buffer support assembly 4 has upper and lower support springs at both ends of the central guide column 43, which are pre-tightened by adjusting nuts 45, providing bidirectional elastic support for the first and second sheet metal plates respectively. This structure can effectively absorb and disperse impact and vibration energy from different directions, suppressing warping and deformation of the sheet metal plates.

[0029] A polyurethane buffer column 47 is coaxially sleeved on the central guide column 43. The polyurethane buffer column 47 is located between the first sheet metal plate 1 and the second sheet metal plate 2, and a buffer gap is left between its upper and lower end faces and the two plates.

[0030] The added polyurethane buffer column 47 serves as a second buffer line. When it undergoes significant displacement with the sheet metal plate, it can contact the two sheet metal plates and provide progressive nonlinear damping. Working in conjunction with the spring, it greatly enhances the structure's energy absorption capacity and impact resistance.

[0031] The buffer connection assembly 5 includes an E-shaped buffer block 51 that covers the side ends of the first sheet metal plate 1 and the second sheet metal plate 2. The outside of the E-shaped buffer block 51 has a metal U-shaped frame 52 with an opening facing the E-shaped buffer block 51.

[0032] In this invention, the buffer connection component 5, which consists of the E-shaped buffer block 51 on the side and the metal U-shaped frame 52, not only restricts the lateral relative displacement of the two plates, but its elastic properties can also absorb lateral impact forces. Together with the bidirectional buffer support component 4, it forms a three-dimensional, all-round anti-deformation protection system, which significantly improves the rigidity and stability of the entire sheet metal structure under dynamic loads and extends its service life.

[0033] The polyurethane buffer column 47 and the central guide column 43 are fitted with an interference fit. This fit completely eliminates the assembly gap between the two components, effectively preventing abnormal noise and fretting wear caused by collisions under vibration and impact conditions, and significantly improving structural durability. Secondly, the interference fit makes the polyurethane buffer column 47 and the central guide column 43 a tightly integrated load-bearing unit, which not only enhances the radial stiffness of the buffer unit but also achieves a smooth transition and synergistic effect between the elastic buffering of the spring and the damping buffering of the polyurethane material.

[0034] The working principle of this application includes the following: First, the operator loosens the locking assembly 33 and loosens the locking nut 334 and adjusting bolt 331, so that the clamping force of the clamping block 332 on the adjusting slider 32 and the side end of the second sheet metal plate 2 is released. In this way, the second sheet metal plate 2, through the cooperation of the strip-shaped through hole 44 and the central guide post, and the now loosened locking assembly 33, forms a state in which it can slide synchronously with the adjusting slider 32, preparing for lateral movement. Secondly, the operator rotates the push bolt 35. Since the push bolt 35 is threadedly connected to the base 31 fixed on the first sheet metal plate 1, the rotational motion is converted into linear motion. The end of the push bolt 35 directly abuts against the adjusting slider 32, thereby precisely driving the adjusting slider to slide horizontally within the groove 34 of the base 31. The connected second sheet metal plate 2 moves synchronously, realizing stepless fine adjustment of the lateral spacing relative to the first sheet metal plate 1. Finally, after the spacing is adjusted to the target value, the operator retightens the locking assembly 33. By tightening the adjusting bolt 331 and the locking nut 334, the clamping block 332 is pulled forcefully, pressing it tightly against the contact surface (with anti-slip texture) of the adjusting slider 32 on the side of the second sheet metal plate 2. The resulting enormous static friction force firmly locks the second sheet metal plate 2, the adjusting slider 32, and the base 31 into a single unit, effectively preventing displacement that may occur under vibration or load, and ensuring the long-term stability of the adjusted spacing.
