Description

Technical Field

[0001] This utility model belongs to the field of machine tool technology, and in particular relates to a machine tool structure with an integrated beam and column. Background Technology

[0002] A machine tool is a core industrial piece of equipment that uses power-driven cutting tools or other tools to cut, grind, stamp, and cast raw materials such as metal, wood, and plastic, producing mechanical parts or finished products with specific shapes, sizes, and precision. Often referred to as the "mother machine of industry," it forms the foundation of the manufacturing production system. Its core function is to achieve "material removal" or "material forming." Through a control system, it precisely controls the relative movement of the cutting tool and the workpiece, meeting processing needs ranging from simple parts to complex precision components. Machine tools can be categorized by processing method, including lathes, milling machines, planers, grinding machines, and drilling machines. Modern machine tools such as CNC lathes and machining centers, controlled by computer programs, can achieve automated multi-process machining, significantly improving precision and efficiency. They are widely used in almost all industrial sectors, including automotive, aerospace, shipbuilding, electronics, and mold making. Their technological level directly determines the overall competitiveness of a country's manufacturing industry.

[0003] In existing machine tool structures, the connection method between the beam and column presents numerous problems. Traditional split structures require complex assembly and debugging, which not only consumes a lot of time and manpower but also easily leads to a decrease in machine tool accuracy due to the accumulation of assembly errors. Although some machine tools with integrated beam and column structures exist, there is still room for improvement. For example, some integrated structures lack rigidity when dealing with heavy-duty machining, resulting in a decrease in machining accuracy; some structures have poor heat dissipation designs, which can easily cause thermal deformation of machine tool components due to heat accumulation, reducing service life; and some lack convenience in maintenance, increasing later maintenance costs and downtime. Utility Model Content

[0005] This utility model is implemented as follows: a crossbeam and column integrated machine tool structure, including a hollow crossbeam.

[0006] The beam is internally fixedly connected with multiple vertical reinforcing plates and multiple horizontal reinforcing plates. The multiple vertical reinforcing plates and multiple horizontal reinforcing plates are evenly spaced along the length and height of the beam, respectively. The multiple vertical reinforcing plates and multiple horizontal reinforcing plates are staggered with each other. The multiple vertical reinforcing plates and multiple horizontal reinforcing plates divide the inner cavity of the beam into multiple cubic cavities. The vertical and horizontal surfaces of the multiple cavities are respectively provided with a first heat dissipation hole and a second heat dissipation hole.

[0007] Preferably, a connecting rail is fixedly connected to the front surface of the crossbeam along its length.

[0008] Preferably, both ends of the lower surface of the crossbeam are vertically fixedly connected to hollow columns.

[0009] Preferably, the bottom ends of the two columns are each horizontally fixedly connected to a connecting plate, and the outer edges of the upper surfaces of the two connecting plates are each vertically perforated with multiple fixing holes.

[0012] Beneficial effects

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] First Embodiment

[0021] Please see Figure 1-3 This utility model provides a technical solution: an integrated beam and column machine tool structure, including a hollow beam 1;

[0022] The beam 1 is internally fixedly connected with multiple vertical reinforcing plates 6 and multiple horizontal reinforcing plates 7. The multiple vertical reinforcing plates 6 and multiple horizontal reinforcing plates 7 are evenly spaced along the length and height of the beam 1, respectively. The multiple vertical reinforcing plates 6 and multiple horizontal reinforcing plates 7 are staggered with each other. The multiple vertical reinforcing plates 6 and multiple horizontal reinforcing plates 7 divide the inner cavity of the beam 1 into multiple cubic cavities. The vertical and horizontal surfaces of the multiple cavities are respectively provided with a first heat dissipation hole 8 and a second heat dissipation hole 9.

[0023] In this embodiment, the crossbeam 1 of the device is provided with a network of reinforcing ribs composed of vertical reinforcing plates 6 and horizontal reinforcing plates 7. These reinforcing ribs are distributed in three dimensions inside the crossbeam 1. Compared with the traditional planar or simple linear reinforcing rib arrangement, it can more effectively resist stress from all directions, thereby improving the lateral load-bearing capacity of the device. At the same time, first heat dissipation holes 8 and second heat dissipation holes 9 are respectively opened on the outer surfaces of multiple vertical reinforcing plates 6, horizontal reinforcing plates 7 and crossbeam 1, which increases the heat dissipation area and improves the heat dissipation efficiency. This ensures that during the operation of the machine tool, heat can be quickly transferred from the heat source to the channel and dissipated through natural convection or forced air cooling. Compared with the traditional machine tool heat dissipation method, the temperature of the key components of the machine tool can be significantly reduced.

[0024] Furthermore, the device has a heat dissipation coating applied to the surface of the heat dissipation channel formed by multiple first heat dissipation holes 8 and multiple second heat dissipation holes 9 inside the crossbeam 1, which can further improve the heat dissipation capacity of the device.

[0025] Furthermore, hollow internal columns 2 are vertically fixedly connected to both ends of the lower surface of the beam 1.

[0026] The bottom ends of the two columns 2 are both horizontally fixed with connecting horizontal plates 4, and the outer edges of the upper surfaces of the two connecting horizontal plates 4 are vertically perforated with multiple fixing holes 5.

[0027] In this embodiment, the crossbeam 1 and the column 2 are cast in one piece, ensuring a tight and seamless connection between them without any assembly gaps. During the casting process, the composition of the material and the pouring temperature are precisely controlled, so that a uniform metal structure is formed at the joint of the crossbeam and the column. The one-piece structure achieves a seamless connection between the crossbeam 1 and the column 2 through the casting process, eliminating the assembly gaps and stress concentration points at the joint surface, greatly improving the overall rigidity, and effectively resisting the overturning moment and vibration interference during high-speed cutting.

[0028] The interior of the column 2 is equipped with the same reinforcing rib network and heat dissipation channel structure as the interior of the crossbeam 1. The connecting plate 4 and the multiple fixing holes 5 on it facilitate the fixed installation of the device on the machine tool equipment.

[0029] Furthermore, a connecting rail 3 is fixedly connected laterally along the length of the front surface of the crossbeam 1.

[0030] In this embodiment, the connecting rail 3 is used to install the tool holder body assembly, which is existing technology, and its specific structure will not be described in detail here.

[0031] Second Embodiment

[0032] Please see Figure 4 Both ends of the outer surface of the crossbeam 1 are fixedly connected to pressure plates 10. Multiple rib holes are opened horizontally through the outer surface of the two pressure plates 10. The multiple rib holes on the two pressure plates 10 are respectively corresponding to each other. A horizontal tie rod 11 is provided between the two corresponding rib holes. Both ends of the multiple horizontal tie rods 11 are provided with external threads. The multiple horizontal tie rods 11 are installed between the two pressure plates 10 through nuts 12.

[0033] In this embodiment, both ends of the tie rod 11 are provided with external threads, which are installed between the two pressure plates 10 through nuts 12. By adjusting the nuts 12, the preload of the structure can be changed, thereby causing the column beam 1 to produce reverse pre-deformation, which counteracts the positive deflection during cutting. Furthermore, it can dynamically optimize rigidity for different processing loads, accurately control the fluctuation of processing accuracy, and further improve the accuracy and stability of the machine tool.

[0034] The working principle and usage process of this utility model: After the utility model is installed, the inside of the crossbeam 1 of the device is provided with a reinforcing rib network composed of vertical reinforcing plates 6 and horizontal reinforcing plates 7. These reinforcing ribs are distributed in three dimensions inside the crossbeam 1. Compared with the traditional planar or simple linear reinforcing rib arrangement, it can more effectively resist stress from all directions, thereby improving the lateral load-bearing capacity of the device. At the same time, first heat dissipation holes 8 and second heat dissipation holes 9 are respectively opened on the outer surfaces of multiple vertical reinforcing plates 6, horizontal reinforcing plates 7 and crossbeam 1, which increases the heat dissipation area and improves the heat dissipation efficiency. This ensures that during the operation of the machine tool, heat can be quickly transferred from the heat source to the channel and dissipated through natural convection or forced air cooling. Compared with the traditional machine tool heat dissipation method, the temperature of the key components of the machine tool can be significantly reduced.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
