[0002] Machining equipment technology is a comprehensive technical system encompassing the research, design, manufacturing, application, maintenance, and optimization of machining equipment. It is a core component of the machinery manufacturing field, aiming to achieve precise processing of materials such as metals and non-metals through various specialized equipment, transforming raw materials or semi-finished products into mechanical parts or products that meet design requirements. Vertical machining centers are CNC machine tools widely used in the machining field, mainly for milling, drilling, tapping, and other processing operations on materials such as metals and plastics.
[0003] Regarding existing related technologies, the inventors believe that the following defects often exist: the column structure of traditional vertical machining centers is mostly an integral structure with a fixed height, which cannot be adjusted according to actual processing needs. This results in poor adaptability of the equipment when facing workpieces of different heights, limiting its application range and reducing the equipment's versatility and flexibility. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the column structure of the existing vertical machining center is usually an integral structure, which is difficult to adapt to different workpiece heights and reduces the versatility of the equipment. Therefore, we propose an adjustable column structure for the vertical machining center.
[0005] To achieve the above objectives, this application adopts the following technical solution: an adjustable column structure for a vertical machining center, comprising a base plate: a first column is fixed to the top of the base plate, a second column is slidably connected inside the first column, a fixed shell is fixed to both sides of the top of the first column, an irregularly shaped block is provided inside the fixed shell, a connecting rod is fixed to the top of the irregularly shaped block, a top plate is fixed to the top of the connecting rod, a horizontal plate is fixed to one side of the irregularly shaped block, an insert is fixed to one side of the horizontal plate, multiple connecting slots for cooperating with the insert are provided on both sides of the second column, a pull plate is slidably connected to the surface of the connecting rod, fixed columns are fixed to both ends of the pull plate, and two fixed slots for cooperating with the fixed columns are provided on both sides of the top of the fixed shell.
[0006] Preferably, a first spring is slidably connected to the surface of the connecting rod, one end of the first spring is fixed to the top plate, and the other end of the first spring is fixed to the pull plate.
[0007] Preferably, limit blocks are fixed on both sides inside the fixed shell, and limit grooves that cooperate with the limit blocks are opened at both ends of the horizontal plate.
[0008] Preferably, two second springs are fixed on one side of the cross plate, the second springs are located on both sides of the insert block, and the other end of the second springs is fixed to the inside of the fixed shell.
[0009] Preferably, guide blocks are fixed on both sides inside the first column, and guide grooves that cooperate with the guide blocks are opened on both sides of the second column.
[0010] Preferably, each of the four corners of the base plate is connected to a threaded rod by a threaded connection, one end of which is fixed with a knob, and the other end of which is fixed with an abutment block.
[0011] Preferably, an anti-slip pad is fixed on one side of the abutment block.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, by pulling the pull plate outward, the fixed column is driven away from the inside of the fixed groove. The connecting rod is pulled to move the irregular block. The irregular block pulls the horizontal plate to move away from the second column. During this process, it causes the insert block to leave the inside of the connecting groove. The operator can flexibly adjust the height of the second column according to the actual processing needs, which facilitates quick adjustment according to processing requirements. This effectively realizes the adjustability of the overall height, significantly improves adaptability, and enhances the versatility and flexibility of the equipment.
[0014] In this invention, by setting up a structure of knob, threaded rod and abutment block, the height of each corner can be adjusted by rotating the threaded rod even in installation environments with uneven ground, ensuring that the equipment remains level, thereby improving processing accuracy and equipment operation stability.

Each end is fixed with a fixing column 13. Two fixing slots 14 are opened on both sides of the top of the fixing shell 5 to cooperate with the fixing column 13. By pulling the pull plate 12 outward, the fixing column 13 is moved away from the inside of the fixing slot 14. The connecting rod 7 is pulled to move the irregular block 6. The irregular block 6 pulls the horizontal plate 9 to move away from the second column 4. During this process, it causes the insert block 10 to move away from the inside of the connecting slot 11. The operator can flexibly adjust the height of the second column 4 according to the actual processing needs, which is convenient for quick adjustment according to the processing needs. It effectively realizes the adjustability of the overall height, significantly improves the adaptability, and enhances the versatility and flexibility of the equipment.
[0024] Reference Figure 2As shown in this embodiment: a first spring 15 is slidably connected to the surface of the connecting rod 7. One end of the first spring 15 is fixed to the top plate 8, and the other end of the first spring 15 is fixed to the pull plate 12. By setting the structure of the first spring 15, when the restriction on the connecting rod 7 is released, the pull plate 12 is pulled outward, and the tensile force of the first spring 15 is used to drive the fixed column 13 away from the inside of the fixed groove 14, so that the operator can use it next time.
[0025] Reference Figure 2 As shown in this embodiment: both sides of the inside of the fixed shell 5 are fixed with limit blocks 16, and both ends of the horizontal plate 9 are provided with limit grooves 17 that cooperate with the limit blocks 16. By setting the structure of limit blocks 16 and limit grooves 17, the movement direction of the horizontal plate 9 is guided and restricted, effectively preventing the horizontal plate 9 from deviating or shaking during the movement.
[0026] Reference Figure 2 As shown in this embodiment: two second springs 18 are fixed on one side of the horizontal plate 9. The second springs 18 are located on both sides of the insert block 10. The other end of the second spring 18 is fixed to the inside of the fixed shell 5. By setting the structure of the second spring 18, when the height of the second column 4 is adjusted, the connecting rod 7 is pulled to drive the irregular block 6 to move. The irregular block 6 pushes the horizontal plate 9 to move in the direction of the second column 4. At the same time, with the tension of the second spring 18, the horizontal plate 9 can be easily pulled to push the insert block 10 into the inside of the connecting groove 11, thereby completing the connection. The operation is very simple.
[0027] Reference Figure 3 and Figure 4 As shown in this embodiment: guide blocks 19 are fixed on both sides inside the first column 2, and guide grooves 20 that cooperate with the guide blocks 19 are opened on both sides of the second column 4.

[0028] Reference Figure 3 and Figure 5 As shown in this embodiment: each of the four corners of the base plate 1 is connected to a threaded rod 21 by a thread. A knob 22 is fixed to one end of the threaded rod 21, and an abutment block 23 is fixed to the other end of the threaded rod 21. By setting the structure of the knob 22, the threaded rod 21 and the abutment block 23, even in an installation environment with uneven ground, the height of each corner can be adjusted by rotating the threaded rod 21 to ensure that the equipment remains level, thereby improving the processing accuracy and the stability of the equipment operation.
[0029] Reference Figure 5As shown in this embodiment: an anti-slip pad 24 is fixed on one side of the abutment block 23. By setting the structure of the anti-slip pad 24, the friction between the abutment block 23 and the ground can be increased, which can effectively prevent the threaded rod 21 from loosening and displacing due to equipment vibration, force and other conditions during the processing.
[0030] Working principle: By pulling the pull plate 12 outward, the user moves the fixed column 13 away from the inside of the fixed groove 14, pulls the connecting rod 7 to move the irregular block 6, and the irregular block 6 pulls the horizontal plate 9 away from the second column 4. During this process, it causes the insert block 10 to leave the inside of the connecting groove 11. The operator can flexibly adjust the height of the second column 4 according to the actual processing needs, which is convenient for quick adjustment according to processing requirements. It effectively realizes the adjustability of the overall height, significantly improves adaptability, and enhances the versatility and flexibility of the equipment. By setting the structure of the first spring 15, when the restriction on the connecting rod 7 is released, the tension of the first spring 15 is used to move the fixed column 13 away from the inside of the fixed groove 14 while pulling the pull plate 12 outward, which is convenient for the operator to use next time. By setting the structure of the limit block 16 and the limit groove 17, the movement direction of the horizontal plate 9 is guided and restricted, effectively preventing the horizontal plate 9 from deviating or shaking during the movement. By setting the structure of the second spring 18, When the height of the second column 4 is adjusted, the connecting rod 7 is pulled to move the irregular block 6. The irregular block 6 pushes the horizontal plate 9 towards the second column 4. At the same time, with the tension of the second spring 18, the horizontal plate 9 can be easily pulled to push the insert block 10 into the interior of the connecting groove 11, thus completing the connection. The operation is very simple. By setting the structure of the guide block 19 and the guide groove 20, it is ensured that the second column 4 always moves in the vertical direction when adjusting the height, avoiding tilting or jamming, and improving the smoothness of the adjustment of the second column 4. By setting the structure of the knob 22, the threaded rod 21 and the abutment block 23, even in the installation environment of uneven ground, the height of each corner can be adjusted by rotating the threaded rod 21 to ensure that the equipment remains level, thereby improving the processing accuracy and the stability of the equipment operation. By setting the structure of the anti-slip pad 24, the friction between the abutment block 23 and the ground can be increased, effectively preventing the threaded rod 21 from loosening and displacing due to equipment vibration, stress and other conditions during processing.
