Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a support component. Background Technology

[0002] Support components are indispensable structural units in many mechanical devices, typically consisting of columns, beams, and connectors for linking and securing the beams to the columns. These components are widely used in various industrial equipment, playing a crucial role, especially in three-axis linkage machinery. For example, in CNC machine tools, large 3D printers, and automated production lines, support components provide a stable frame structure, ensuring the rigidity and precision of the entire mechanism. These devices often require high-speed, high-precision movements during operation, thus placing extremely stringent performance requirements on the support components. A well-designed support component not only provides sufficient load-bearing capacity but also effectively resists vibration and deformation, thereby guaranteeing the machining accuracy and operational efficiency of the equipment.

[0003] In traditional support component designs, connectors typically use simple planar contact methods to fix beams and columns, such as ordinary bolts or welding. While this design is simple and easy to manufacture, it has several significant drawbacks. First, the planar contact method results in a limited contact area, making it difficult to evenly distribute pressure and easily leading to stress concentration in localized areas, thus reducing the overall load-bearing capacity. Second, this connection method lacks automatic alignment, making it prone to minor displacements and deviations during equipment operation, affecting machining accuracy. Furthermore, traditional designs also suffer from poor impact resistance and inconvenient installation and adjustment. These shortcomings are particularly pronounced in modern mechanical equipment that demands high precision and stability, severely restricting performance improvements. Utility Model Content

[0004] The main purpose of this utility model is to propose a support component that aims to solve the technical problems of insufficient load-bearing capacity, poor stability, and inconvenient installation and adjustment of existing support components.

[0005] To achieve the above objectives, the present invention proposes a support component comprising a column, a beam, a first connector, and a second connector. The column has a pressure-bearing surface; the beam has a pressure-applying surface; the first connector is fixedly disposed on the column and protrudes from the pressure-bearing surface, and the first connector has a first concave arc surface; the second connector is fixedly disposed on the beam and protrudes from the pressure-applying surface, and the second connector has a first convex arc surface adapted to the first concave arc surface, the first convex arc surface being tightly fitted to the first concave arc surface.

[0006] Optionally, the first connector extends in the height direction of the column, and a positioning groove is formed at the top of the first connector, the groove wall surface of the positioning groove being formed as the first concave arc surface.

[0007] Optionally, the peripheral wall surface of the positioning groove is formed as the first concave arc surface, and the first concave arc surface is a conical surface.

[0008] Optionally, the first concave arc surface is a conical surface;

[0009] The second connector includes a cylinder and a cone connected together. The end of the cylinder away from the cone is fixedly disposed on the pressure surface. The cone tip extends away from the pressure surface. The peripheral wall surface of the cone is formed as the first convex arc surface.

[0010] Optionally, the second connector has a through hole extending from the tip of the cone to the end of the cylinder away from the cone.

[0011] Optionally, the bottom surface of the crossbeam is formed as the pressure-applying surface;

[0012] The column includes a support column and a fixed column. The top surface of the support column is formed as the pressure-bearing surface. The first connector and the fixed column are both fixedly installed on the support column. The fixed column protrudes from the pressure-bearing surface and is located on one side of the crossbeam.

[0013] The support assembly also includes a locking element, which is fixedly connected to the fixed column and the crossbeam respectively.

[0014] Optionally, the locking element includes a through rod, a first nut, a second nut, and a third nut;

[0015] The through rod passes through the fixed column and is inserted into the crossbeam;

[0016] The end of the through rod away from the crossbeam is fixedly connected to one side of the fixed column by the first nut;

[0017] The fixed section on the through rod located between the fixed rod and the crossbeam is fixedly connected to the other side of the fixed column by the second nut, and the fixed section is fixedly connected to one side of the crossbeam by the third nut.

[0018] Optionally, the fixed section is provided with a third connector and a fourth connector;

[0019] One end of the third connector abuts against the second nut, and the other end of the third connector forms a second concave arc surface;

[0020] One end of the fourth connector has a second convex arc surface that is adapted to the second concave arc surface, the second convex arc surface is tightly fitted to the second concave arc surface, and the other end of the fourth connector is pressed against the fixing post.

[0021] Optionally, both the second concave arc surface and the second convex arc surface are conical surfaces.

[0022] Optionally, the number of columns is at least two, and each column is provided with the first connecting member on its pressure-bearing surface. The number of second connecting members provided on the crossbeam is the same as the number of first connecting members, so that they correspond one-to-one.

[0023] The support component of this utility model features a first concave arc surface of the first connector that closely fits the first convex arc surface of the second connector. This design firstly increases the contact area, resulting in a more uniform pressure distribution and thus improving the overall load-bearing capacity, solving the problem of stress concentration that easily occurs with traditional planar contacts. Secondly, the arc surface contact has an automatic alignment function. When the beam is under stress, the convex arc surface of the second connector will naturally slide to the optimal stress position on the concave arc surface of the first connector. This not only reduces the alignment difficulty during installation but also automatically adjusts the position during use, effectively reducing the impact of minute displacements and deviations on machining accuracy. Furthermore, the arc surface contact also has a certain degree of flexibility, which can absorb and buffer impact forces to a certain extent, improving the impact resistance of the support component. This innovative design not only improves the performance and reliability of the support component but also provides a better support solution for high-precision, high-stability modern mechanical equipment.

[0034] This utility model proposes a support component.

[0035] In the embodiments of this utility model, such as Figures 1 to 3As shown, the support assembly includes a column 1, a beam 2, a first connector 3, and a second connector 4. The column 1 has a pressure-bearing surface 111; the beam 2 has a pressure-applying surface 21; the first connector 3 is fixedly disposed on the column 1 and protrudes from the pressure-bearing surface 111, and the first connector 3 forms a first concave arc surface 311; the second connector 4 is fixedly disposed on the beam 2 and protrudes from the pressure-applying surface 21, and the second connector 4 has a first convex arc surface 421 that is adapted to the first concave arc surface 311, and the first convex arc surface 421 is tightly fitted to the first concave arc surface 311.

[0036] Specifically, the column 1 is the vertical support part of the support assembly, and can be made of metal materials such as steel, aluminum alloy, etc., or other materials with sufficient strength. The column 1 has a pressure-bearing surface 111, which is located at the top of the column 1 and is used to withstand the pressure from the crossbeam 2. The crossbeam 2 is the horizontal support part of the support assembly, and can also be made of metal or other high-strength materials. The crossbeam 2 has a pressure-applying surface 21, which is located at the bottom of the crossbeam 2 and is used to apply pressure to the column 1. The first connector 3 is fixedly installed on the column 1 and protrudes from the pressure-bearing surface 111. Here, "fixedly installed" can be welding, bolting, riveting, or other secure connection methods. The first connector 3 forms a first concave arc surface 311, which can be a spherical surface, a conical surface, or other curved surface shape. The second connector 4 is fixedly installed on the crossbeam 2 and protrudes from the pressure-applying surface 21. The second connector 4 has a first convex arc surface 421 that matches the first concave arc surface 311. The shape of this convex arc surface matches the first concave arc surface 311 and can be a spherical, conical, or other curved surface. The first convex arc surface 421 fits tightly against the first concave arc surface 311; this tight fit can be achieved through precision machining and appropriate installation. The advantages of this design are: by using arc surface contact, the contact area between the column 1 and the beam 2 is increased, resulting in a more uniform pressure distribution and thus improving the overall load-bearing capacity; simultaneously, the arc surface contact has an automatic centering function, automatically adjusting to the optimal stress position during use, reducing installation errors and displacement deviations during use, and improving the stability and precision of the support assembly; furthermore, the arc surface contact also has a certain degree of flexibility, which can absorb and buffer impact forces to a certain extent, improving the impact resistance and service life of the support assembly. This innovative design not only improves the performance and reliability of the support assembly but also provides a better support solution for high-precision, high-stability modern mechanical equipment.

[0037] Optionally, the first connector 3 extends in the height direction of the column 1, and a positioning groove 31 is formed at the top of the first connector 3, and the groove wall surface of the positioning groove 31 is formed as the first concave arc surface 311.

[0038] Specifically, the "height direction" here refers to the vertical direction of the column 1. The height of the first connector 3 can be designed according to actual needs. The positioning groove 31 is set at the top of the first connector 3, a design that places the first concave arc surface 311 at the very top of the first connector 3. The groove wall surface of the positioning groove 31 is formed as the first concave arc surface 311, which means that the concave arc surface is continuous and can be spherical, frustum-shaped, or other suitable curved surface shapes.

[0039] Instead of creating a protruding structure on the side wall and then setting the groove, the positioning groove 31 is located on the top of the first connector 3. This design has significant advantages in the stress process when the crossbeam 2 presses against the first connector 3. First, this design allows the vertical force to be directly transmitted to the column 1, reducing force dispersion and offset, and improving the load-bearing capacity and stability of the support assembly. Second, the positioning groove 31 at the top can better accommodate and guide the second connector 4, making it easier for the crossbeam 2 to find the correct position during installation and use, improving the convenience and accuracy of installation.

[0040] Optionally, the peripheral wall surface of the positioning groove 31 is formed as the first concave arc surface 311, and the first concave arc surface 311 is a conical surface.

[0041] Specifically, the "peripheral wall" here refers to the entire inner wall of the positioning groove 31, not the bottom or a particular side. A conical surface is a special type of curved surface that gradually expands from a smaller circle to a larger circle, forming a shape similar to the inner surface of a cone.

[0042] Choosing a conical surface as the shape of the first concave arc surface 311 offers several advantages. First, the conical surface provides a progressive contact area, which helps guide the second connector 4 to accurate positioning during installation. Second, the conical surface design allows for angle adjustment within a certain range, increasing the flexibility of the support assembly and enabling it to adapt to minor installation errors or positional changes during use. Furthermore, the conical surface structure provides a larger contact area while maintaining stability, which facilitates more even pressure distribution and improves overall load-bearing capacity. In addition, the conical surface design has good self-locking properties, automatically increasing friction under stress, further enhancing connection stability. Finally, the conical surface structure is relatively easy to process and manufacture, which helps reduce production costs and ensure product consistency. In summary, using a conical surface as the first concave arc surface 311 offers significant advantages in improving the positioning accuracy, adjustment flexibility, load-bearing capacity, stability, and production efficiency of the support assembly, providing effective technical support for optimizing the performance of the support assembly.

[0043] Optionally, the first concave arc surface 311 is a conical surface;

[0044] The second connector 4 includes a cylinder 41 and a cone 42 connected to each other. The end of the cylinder 41 away from the cone 42 is fixedly disposed on the pressure surface 21. The cone tip of the cone 42 extends away from the pressure surface 21. The peripheral wall surface of the cone 42 is formed as the first convex arc surface 421.

[0045] Specifically, cylinder 41 is a columnar structure with a fixed diameter, while cone 42 is a gradually tapering structure. The end of cylinder 41 away from cone 42 is fixedly disposed on pressure surface 21, meaning that one end of cylinder 41 is connected to the bottom of crossbeam 2 (pressure surface 21). The cone tip of cone 42 extends away from pressure surface 21, that is, the tip of cone 42 points downward and is opposite to the first connector 3 on column 1.

[0046] The peripheral wall surface of the cone 42 is formed as a first convex arc surface 421. This design allows the outer surface of the cone 42 to fit tightly with the first concave arc surface 311 (also a cone surface) of the first connector 3.

[0047] It's easy to understand that the fit between the conical body 42 and the conical surface provides an automatic alignment mechanism, automatically adjusting to the optimal position during installation and use. Simultaneously, the conical structure provides a larger contact area, which helps to evenly distribute pressure. The design of the cylinder 41 provides stability and strength to the entire structure. Furthermore, this structure has a certain self-locking function, automatically increasing friction under stress, further improving connection stability. The design of the conical body 42 also allows for angle adjustment within a certain range, increasing the adaptability of the support assembly. In summary, this design has significant advantages in improving the positioning accuracy, load-bearing capacity, stability, and flexibility of the support assembly, while also facilitating manufacturing and installation, providing effective technical support for optimizing the performance of the support assembly.

[0048] Optionally, the second connector 4 is formed with a through hole 43, which extends from the tip of the cone 42 to the end of the cylinder 41 away from the cone 42.

[0049] Specifically, the through hole 43 extends from the tip of the cone 42 to the end of the cylinder 41 away from the cone 42. Here, "through hole 43" refers to a hole that runs through the entire second connector 4.

[0050] It is easy to understand that the through hole 43 can be used to accommodate fasteners such as bolts or pins, allowing the second connector 4 to be more securely connected to the crossbeam 2, while also providing space for possible adjustments. Secondly, the presence of the through hole 43 reduces the weight of the second connector 4, reducing the overall mass of the support assembly while maintaining strength. Furthermore, the through hole 43 can also be used to route cables, hydraulic or pneumatic lines, giving the support assembly more functionality. In some applications, the through hole 43 can also be used to observe the internal condition or perform maintenance. Finally, the design of the through hole 43 may also improve heat dissipation performance, especially under high-load operating environments. In summary, this design of the second connector 4 with a through hole 43 has significant advantages in improving the connection strength of the support assembly, reducing weight, increasing functionality, facilitating maintenance, and improving heat dissipation, providing more possibilities for improving the performance and practicality of the support assembly.

[0051] Optionally, the bottom surface of the crossbeam 2 is formed as the pressure surface 21;

[0052] The column 1 includes a support column 11 and a fixed column 12. The top surface of the support column 11 is formed as the pressure-bearing surface 111. The first connector 3 and the fixed column 12 are both fixedly installed on the support column 11. The fixed column 12 protrudes from the pressure-bearing surface 111 and is located on one side of the crossbeam 2.

[0053] The support assembly also includes a locking member 5, which is fixedly connected to the fixed column 12 and the crossbeam 2 respectively.

[0054] It's easy to understand that by dividing column 1 into support column 11 and fixed column 12, the load-bearing and fixing functions are separated, making the structure more stable and reliable. Support column 11 bears the main load-bearing task, while fixed column 12 and locking element 5 provide additional fixation and stability. This design increases the load-bearing capacity and resistance to lateral forces of the entire support assembly. At the same time, the introduction of locking element 5 provides a reliable fixing method, preventing the crossbeam 2 from accidentally moving or falling off during use. Furthermore, this design improves the adjustability and flexibility of the support assembly, allowing for appropriate adjustments in different application scenarios.

[0055] Optionally, the locking member 5 includes a through rod 51, a first nut 52, a second nut 53, and a third nut 54;

[0056] The through rod 51 passes through the fixed column 12 and is inserted into the crossbeam 2;

[0057] The end of the through rod 51 away from the crossbeam 2 is fixedly connected to one side of the fixed column 12 by the first nut 52;

[0058] The fixed section 511 on the through rod 51, located between the fixed rod and the crossbeam 2, is fixedly connected to the other side of the fixed column 12 by the second nut 53, and the fixed section 511 is fixedly connected to one side of the crossbeam 2 by the third nut 54.

[0059] Specifically, the surface of the through rod 51 is provided with a threaded structure that can cover the entire length of the through rod 51, or at least the part that needs to contact the nut. This threaded structure allows the first nut 52, the second nut 53, and the third nut 54 to move freely and be fixed on the through rod 51.

[0060] It is easy to understand that the through rod 51 provides a rigid element throughout the entire connection structure, greatly enhancing the overall stability and load-bearing capacity. Secondly, the use of multiple nuts allows for adjustment and fixation of the connection from multiple directions, which not only improves the reliability of the connection but also increases the flexibility of adjustment. The cooperation of the first nut 52 and the second nut 53 allows the fixing post 12 to be securely locked onto the through rod 51, while the third nut 54 ensures a stable connection between the crossbeam 2 and the entire structure. Furthermore, this design facilitates installation and disassembly, which is beneficial for later maintenance and adjustment. The use of nuts also allows for fine-tuning; the height and level of each support component can be finely adjusted by changing the position of the nuts.

[0061] Optionally, the fixed section 511 is provided with a third connector 6 and a fourth connector 7;

[0062] One end of the third connector 6 abuts against the second nut 53, and the other end of the third connector 6 forms a second concave arc surface 61;

[0063] One end of the fourth connector 7 is formed with a second convex arc surface 71 that is adapted to the second concave arc surface 61. The second convex arc surface 71 is tightly fitted to the second concave arc surface 61, and the other end of the fourth connector 7 is pressed against the fixing post 12.

[0064] It is easy to understand that by introducing the third connector 6 and the fourth connector 7, an adjustable buffer mechanism is created between the through rod 51 and the fixed column 12. This mechanism can absorb some vibration and impact, improving the stability and service life of the entire support assembly. Secondly, the concave-convex arc surface design allows for angle adjustment within a certain range, which increases the flexibility of the support assembly, enabling it to adapt to minor installation errors or positional changes during use. Furthermore, this design provides a larger contact area, which is beneficial for more evenly distributing pressure and improving the overall load-bearing capacity. In addition, the concave-convex arc surface fit also has an auto-alignment function, which can automatically adjust to the optimal stress position during use. Finally, this design also facilitates disassembly and maintenance; the pressure between the third connector 6 and the fourth connector 7 can be changed by adjusting the position of the second nut 53, thereby achieving fine adjustment.

[0065] Optionally, both the second concave arc surface 61 and the second convex arc surface 71 are conical surfaces. The conical surface design offers several advantages. It provides a progressive contact area, facilitating automatic centering and position adjustment. The conical surface also allows for angular adjustment within a certain range, increasing the adaptability of the support assembly. Simultaneously, the conical surface structure can provide a larger contact area while maintaining stability, which is beneficial for more evenly distributing pressure. Furthermore, the conical surface design has good self-locking properties, automatically increasing friction under stress, further improving the stability of the connection.

[0066] Optionally, the number of columns 1 is at least two, and each column 1 has the first connecting member 3 on its pressure-bearing surface 111. The number of second connecting members 4 on the crossbeam 2 is the same as the number of first connecting members 3, so that they correspond one-to-one.

[0067] Specifically, there are at least two columns 1, meaning the support assembly can have multiple support points, improving overall stability and load-bearing capacity. Each column 1 has a first connector 3 on its pressure-bearing surface 111, ensuring that each support point has the same connection mechanism. Correspondingly, the number of second connectors 4 on the crossbeam 2 is the same as the number of first connectors 3, and they correspond one-to-one. The advantages of this design are: First, the multiple support points significantly enhance the stability and load-bearing capacity of the entire support assembly, enabling it to adapt to larger loads and more complex working environments. Second, the uniformity of the connection mechanism at each support point simplifies the manufacturing and installation process, while also facilitating maintenance and replacement. Third, the multi-point support design increases the rigidity of the entire structure, reduces deformation and vibration, and improves working accuracy. Finally, this design also has good scalability, allowing the number of support points to be increased or decreased according to actual needs, enabling the support assembly to adapt to different application scenarios.

[0068] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
