Description

Technical Field

[0001] This utility model relates to the technical field of CNC machine tools, specifically to a machine tool column for a CNC machine tool. Background Technology

[0002] The CNC machine tool column is a crucial structural component, playing a vital role in supporting the machine's vertical movement. The column primarily supports the spindle head, accommodating the spindle's Z-axis movement. As a key component connecting the machine bed, spindle, and tool magazine, its design must be carefully considered. For the spindle, proper column installation is essential for producing high-quality parts, and the column's installation is primarily reflected in its perpendicularity to the worktable.

[0003] Chinese patent CN218556244U discloses a CNC machine tool column with anti-tipping function, including a machine tool column body, a support component at the lower end of the slide channel, and two sets of support components, with the two sets of support components respectively arranged on both sides of the lower block.

[0004] In the above solution, the machine tool column is supported by a solid ball, telescopic rod, limit plate and push plate to prevent it from tipping over. However, it has the following disadvantages: no support devices are set on the left and right sides of the machine tool column, which makes the machine tool column easy to bend and twist under stress, thereby reducing the rigidity of the column. Utility Model Content

[0005] The purpose of this utility model is to provide a machine tool column for CNC machine tools to solve the problem that the lack of support devices on the left and right sides of the machine tool column makes it prone to bending and twisting under stress, thereby reducing the rigidity of the column.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a machine tool column of a CNC machine tool, comprising a plurality of support plates, wherein the plurality of support plates are respectively fixed on the left and right sides of the column body, a connecting plate is fixed between the plurality of support plates, the connecting plate is fixed to the column body, two slide rails are fixed on the front side of the column body, and reinforcing ribs are fixed at the four corners of the top surface of the column body, and a plurality of placement slots are provided on the rear side of the column body, wherein counterweights are placed on the inner wall of the placement slots.

[0007] Preferably, the inner wall of the column body is provided with a number of heat dissipation holes.

[0008] Preferably, the column body has several receiving grooves on both the left and right sides, and the bottom surface of the receiving groove has a threaded hole, and the inner wall of the threaded hole is threaded with a fastening bolt.

[0009] Preferably, two elastic washers are fixed to the bottom surface of the column body, and the fastening bolts pass through the elastic washers.

[0010] Preferably, the connecting plate is mounted vertically on the support plate.

[0011] Preferably, the bottom surface of the column body is inverted V-shaped.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By cooperating with the support plate and the connecting plate, the cutting force and gravity borne by the column body can be evenly distributed to the base, avoiding local stress concentration, effectively increasing the bending and torsional resistance of the column body, effectively preventing the column body from shaking, thereby improving the rigidity of the column body; by adding or removing counterweights, the operator can easily adjust the center of gravity of the column body, ensuring that the machine tool remains stable under high-speed movement or high-load conditions.

[0014] Second, the ventilation holes promote airflow within the column body, allowing heat to dissipate quickly and ensuring uniform temperature across all parts of the column. This effectively prevents localized thermal stress concentration and reduces thermal deformation caused by temperature increases. The fastening bolts secure the column body to the fixed surface, ensuring a tight connection between the bottom surface and the fixed surface, forming a unified structure and preventing loosening or displacement during operation. The elastic gaskets absorb vibrations generated during operation, making the column more stable and effectively reducing vibration transmission to the base or ground, thus improving the column's stability.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, a CNC machine tool column includes several support plates 1, which are respectively fixed on the left and right sides of the column body 2. A connecting plate 3 is fixed between the support plates 1 and the connecting plate 3 is fixed to the column body 2. Two slide rails 4 are fixed on the front side of the column body 2. Reinforcing ribs 5 are fixed at the four corners of the top surface of the column body 2. Several placement slots 6 are opened on the rear side of the column body 2. Counterweights 7 are placed on the inner wall of the placement slots 6. The connecting plate 3 is vertically installed on the support plates 1. The bottom surface of the column body 2 is inverted V-shaped.

[0022] During use, the cutting force and gravity borne by the column body 2 can be evenly distributed to the base through the cooperation of the support plate 1 and the connecting plate 3, avoiding local stress concentration, effectively increasing the bending and torsional resistance of the column body 2, effectively preventing the column body 2 from shaking, thereby improving the rigidity of the column body 2; by adding or removing the counterweight 7, the operator can easily adjust the center of gravity of the column body 2 to ensure that the machine tool remains stable under high-speed movement or high load conditions.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the inner wall of the column body 2 has several heat dissipation holes 8, and the left and right sides of the column body 2 have several receiving grooves 9. The bottom surface of the receiving groove 9 has a threaded hole 10, and the inner wall of the threaded hole 10 is threaded with a fastening bolt 11. The bottom surface of the column body 2 is fixed with two elastic washers 12, and the fastening bolt 11 passes through the elastic washers 12.

[0024] During use, the heat dissipation holes 8 promote air circulation inside the column body 2, allowing heat to dissipate quickly and ensuring uniform temperature across all parts of the column body 2. This effectively prevents localized thermal stress concentration and reduces thermal deformation caused by temperature increases. The fastening bolts 11 secure the column body 2 to the fixed surface, ensuring a tight connection between the bottom surface and the fixed surface, forming a unified structure and preventing loosening or displacement during operation. The elastic gaskets 12 absorb vibrations generated during operation, making the column body 2 more stable and effectively reducing vibration transmission to the base or ground, thus improving its stability.
