Description

Technical Field

[0001] The utility model relates to the technical field of machine tool equipment, in particular to a column structure of a numerically controlled machine tool. Background Art

[0002] CNC machine tools (CNC machining centers) are core equipment in modern manufacturing. They realize automated precision machining of various metal parts through computer programming. These machine tools are widely used in industries such as aviation, automobiles, mold manufacturing, and electronic equipment. Their high degree of automation and precision are the key to achieving efficient production. CNC machine tools are mainly divided into CNC milling machines, CNC lathes, CNC drilling machines, and CNC grinders according to their processing functions. Each machine tool is designed with a special column structure to support its operating head and tool system. The design of the column directly affects the rigidity, stability, and processing range of the machine tool. Therefore, the performance of the column is an important parameter for measuring the quality of CNC machine tools. The column body is usually fixed or designed with limited adjustment capabilities to ensure the accuracy and stability of the machine tool when processing various workpieces. However, with the increasing complexity and size of workpieces, traditional column designs are often difficult to meet changing industrial needs.

[0003] In practical applications, a taller or more adaptable column structure is often required for processing large or irregularly shaped workpieces. For example, when manufacturing large engine components in the aviation industry or processing large turbine blades in the energy industry, the required column height may far exceed the design limitations of standard CNC machine tools. In these cases, if the machine tool column does not have sufficient adjustment flexibility, it may be necessary to replace the column to adapt to these special process requirements. This replacement process is not only time-consuming and costly, but also involves complex mechanical operations and may bring operational safety risks. Therefore, there is an urgent need to develop a new type of CNC machine tool column structure that can provide higher flexibility and safety to adapt to complex and changing processing requirements, while reducing production interruptions and potential dangers caused by column adjustments.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example

[0030] See also Figure 1-5 As shown, the utility model provides a technical solution for a column structure of a CNC machine tool: a column structure of a CNC machine tool, comprising a machine tool body 1, a column body 2 is installed on the upper end surface of the machine tool body 1, a lifting mechanism 3 for adjusting the height of the column body 2 is installed on the inner side of the column body 2, a guide mechanism 4 is provided on both sides of the column body 2, and a padding component 5 is detachably installed between the machine tool body 1 and the column body 2;

[0031] The lifting mechanism 3 includes a cylinder 301 and a pressure plate 303. The cylinder 301 is fixedly mounted on the upper end surface of the machine tool body 1 and is located inside the column body 2. The output end of the cylinder 301 is connected to the top plate 302. The pressure plate 303 is arranged inside the column body 2. The pressure plate 303 is used to bear and distribute the lifting force transmitted from the cylinder 301 to the top plate 302. During the lifting process, the pressure plate 303 directly contacts the top plate 302. When the cylinder 301 is activated, the top plate 302 is pushed. When moving upward, the force applied by the top plate 302 is transmitted through the pressure plate 303. In the specific design, the pressure plate 303 is designed to have sufficient strength and rigidity (such as carbon steel, alloy steel, etc.) to evenly distribute the lifting force from the top plate 302. After the height adjustment is completed, a cushioning component 5 of a corresponding height can be set to adjust the starting height of the column body 2, and the guide mechanism 4 ensures that the column body 2 remains stable during the lifting process, thereby improving the accuracy and safety of the processing process.

[0032] The guide mechanism 4 includes a guide bracket 401, a guide hole 402, and a guide column 403. The guide bracket 401 is fixedly installed on both sides of the column body 2 and is located on the upper end surface of the machine tool body 1. The guide holes 402 are opened on both sides of the column body 2. The guide column 403 is arranged between the guide bracket 401 and the machine tool body 1. The column body 2 is slidably connected with the guide column 403 through the guide hole 402. During the lifting and lowering process of the column body 2, the column is lifted and lowered in a predetermined direction through the sliding connection between the guide hole 402 and the guide column 403. This structure not only ensures that the column body 2 can be accurately aligned and fixed after reaching the predetermined height, but also prevents the column body 2 from tipping over during the lifting process, thereby ensuring the safety of the operation.

[0033] The pad height assembly 5 includes a pair of pads 501, which are detachably installed between the machine tool body 1 and the column body 2. The top shape of the pad 501 matches the bottom shape of the column body 2. The two sides and the center of the pad 501 are respectively formed with guide column holes 502 and cylinder holes 503 by splicing each other. In the specific implementation process, the pad 501 can be designed according to the actual column height requirements. When the column height needs to be adjusted, the technician first needs to release the connection between the column body 2 and the machine tool body 1, and then operate the cylinder 301 to lift the column body 2 and exceed the height of the pad 501 itself, and then put the two pads 501 into the lower end of the column body 2 and calibrate the position. After the calibration, operate the cylinder 301 to lower the column body 2. When the bottom of the column body 2 is completely fitted with the pad 501, it can be locked. This design can ensure that the column height can be adjusted without affecting the lifting of the column. The operation is simple and the stability is high.

[0034] The upper end surfaces of the machine tool body 1 and the pad 501 are provided with a protrusion 6, and the lower end surfaces of the pad 501 and the column body 2 are provided with a recessed portion 7 matched with the protrusion 6. By arranging the protrusion 6 and the recessed portion 7 that match each other, the direct connection of the components can be facilitated, the docking accuracy can be ensured, the docking efficiency can be improved, and the stability of the overall structure can also be improved.

[0035] A limit groove 8 is provided on the upper end surface of the machine tool body 1. Through the limit groove 8, the cylinder 301 can remain fixed in the operating environment of the machine tool to ensure that it is always located at the center position of the column body 2. This design ensures the position accuracy and stability of the column body 2 during the jacking process, thereby enhancing the reliability and efficiency of the entire column during high-load jacking.

[0036] The back side of the pressure plate 303 and the back side of the top plate 302 are both connected with a reinforcing plate 9. In this embodiment, the specific position of the reinforcing plate 9 is as follows: Figure 3 As shown, one side of the reinforcing plate 9 on the back of the pressure plate 303 is directly fitted with the inner side surface of the column body 2, and the other side is directly fitted with the back surface of the pressure plate 303, and the fitting surface extends to the center position of the back surface of the pressure plate 303. In a specific implementation, the top plate 302 and the reinforcing plate 9 on the back surface of the pressure plate 303 can be arranged in a ring array to achieve the effect of uniformly dispersing stress.

[0037] The working principle of the utility model is as follows:

[0038] When the column structure of a CNC machine tool of the present embodiment is in use, the operator first activates the cylinder 301 through the control system according to the needs of processing the workpiece, the cylinder 301 begins to extend, and the top plate 302 at its output end is pushed upward, and the force transmitted by the top plate 302 is received and evenly distributed by the pressure plate 303. The strength and rigidity of the pressure plate 303 ensure that the lifting force is effectively transmitted inside the column body 2, thereby realizing the precise vertical lifting of the column body 2. During this process, the sliding connection between the guide holes 402 located on both sides of the column body 2 and the guide columns 403 installed on the guide bracket 401 ensures that it rises and falls along the predetermined direction, improves the accuracy of the installation position and the stability of the lifting. After reaching the predetermined height, the cushion block 501 is installed on the machine tool bed 1, and then the cylinder 301 is allowed to fall back. When the column body 2 is stably pressed on the cushion block 501, it can be further fixed.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
