Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a column for a gantry CNC machine tool. Background Technology

[0002] As a key piece of equipment used in modern manufacturing for processing large and complex parts, the column of the gantry CNC machine tool is an important supporting component, like the "backbone" of the entire machine tool. It not only bears the weight of core components such as the machine tool beam and spindle box, but also withstands various complex loads such as cutting force and gravity during the processing. Its structural strength, rigidity and dynamic performance directly affect the machining accuracy, stability and reliability of the machine tool.

[0003] Application No. 202421090213.3 discloses a column structure for a CNC machine tool, including a machine tool body. A column body is disposed on the upper end face of the machine tool body. A lifting mechanism for adjusting the height of the column body is installed inside the column body. Guide mechanisms are provided on both sides of the column body. A detachable shim assembly is provided between the machine tool body and the column body. This utility model has a simple structure and reasonable design. The column structure can support precise height adjustment of the column body and ensure stability and accuracy during the lifting process. In addition, the detachable design of the shim assembly can adjust the starting height according to processing requirements, thereby providing users with personalized operation options, ensuring operational efficiency and safety, improving the user experience, and also helping to improve processing quality and machine tool adaptability.

[0004] The above solution has shortcomings in use. When using shims to raise the column, the column cannot be supported at different heights because the height of the shims is fixed, which will further affect the complex and ever-changing processing requirements. Therefore, we provide a column for gantry CNC machine tools. Utility Model Content

The two sets of hydraulic push rods 301 are fixedly connected to a cross plate 303. The cross plate 303 can reinforce the connection between the hydraulic push rods 301 and further ensure its stability when lifting the column body 2.

[0034] Second Embodiment

[0035] As attached Figure 2 Appendix Figure 4 With appendix Figure 5As shown: The support assembly 4 is located below the column body 2 and inside the casing 1. It includes two sets of support plates 401 inside the casing 1, a set of support slots 402 on one side of each support plate 401, and a support structure located below the column body 2 for inserting into the support slots 402 to support the column body 2. The support structure of the support assembly 4 includes a motor 403 installed on the bottom surface of the column body 2. The output end of the motor 403 is fixedly connected to a turntable 404. The outer surface of the turntable 404 is hinged with a ring of push-pull plates 405. The other end of each push-pull plate 405 is hinged with an insert plate 406. Each insert plate 406... The other end of the plate 406 extends into the interior of the support groove 402. Before adjusting the height of the column body 2, the motor 403 is controlled to rotate forward. The turntable 404 will rotate and drive the push-pull plate 405 to deflect. The other end of the push-pull plate 405 will pull the insert plate 406 to separate from the interior of the support groove 402. As the hydraulic push rod 301 pushes the column body 2 to complete the height adjustment, the motor 403 is controlled to rotate in reverse. The turntable 404 will rotate in reverse and push the push-pull plate 405. The other end of the push-pull plate 405 will push the insert plate 406, and the insert plate 406 will be inserted into the support groove 402 at the appropriate height.

One side of each guide block 502 is connected to the outer surface of the column body 2. When the column body 2 moves, it will drive the guide block 502 to slide inside the positioning frame 501, further ensuring the stability of the column body 2 when it is lifted and lowered.

[0039] Working principle: When the height of the column body 2 is adjusted, the control motor 403 rotates forward, the turntable 404 rotates and drives the push-pull plate 405 to deflect. The other end of the push-pull plate 405 pulls the insert plate 406 to separate from the support groove 402. Then, the control hydraulic push rod 301 extends and pushes the column body 2 upward. When the column body 2 reaches the appropriate height, the control motor 403 reverses, the turntable 404 reverses, the turntable 404 pushes the push-pull plate 405, and the other end of the push-pull plate 405 pushes the insert plate 406. The insert plate 406 is inserted into the support groove 402 at the appropriate height, thus supporting the column body 2 at different heights, which can be used for complex and varied processing needs.
