Abstract
Description
Technical Field
[0001] This utility model relates to a support frame for a CNC engraving machine, belonging to the technical field of CNC engraving machine support device design. Background Technology
[0002] CNC engraving machines can perform relief, flat, and openwork engraving on wooden doors, furniture, metal, acrylic, and other materials. They offer high engraving speed and precision, using the free movement of a milling cutter to carve the material. However, CNC engraving machines are typically supported by a support frame. Insufficient support frame strength can cause wobbling during engraving, affecting accuracy. Furthermore, frame instability can lead to milling cutter deviations, resulting in unsatisfactory relief, flat, or openwork engraving effects. Prolonged operation under unstable conditions can cause additional wear and tear on the machine's mechanical components. Therefore, a CNC engraving machine support frame that improves the support strength of the main frame is needed. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a CNC engraving machine support frame with reasonable and simple structure and strong support force.
[0004] To achieve the above-mentioned utility model objectives, the technical solution adopted by this utility model is as follows: A support frame for a CNC engraving machine, comprising a first side machine tool column assembly, a second side machine tool column assembly, and a machine tool Y-axis longitudinal beam;
[0005] Both the first side machine tool column group and the second side machine tool column group contain at least two machine tool columns, and the number of machine tool columns in the first side machine tool column group is the same as the number of machine tool columns in the second side machine tool column group; the machine tool columns in the first side machine tool column group are symmetrical to the corresponding machine tool columns in the second side machine tool column group, and a machine tool bottom crossbar is provided between the bottoms of the two symmetrical machine tool columns, with both ends of the machine tool bottom crossbar fixed to the bottom of the corresponding machine tool column;
[0006] The machine tool has two Y-axis longitudinal beams. One machine tool Y-axis longitudinal beam is fixedly supported on the top of all machine tool columns in the first side machine tool column group, and the other machine tool Y-axis longitudinal beam is fixedly supported on the top of all machine tool columns in the second side machine tool column group.
[0007] Several machine tool table crossbars are provided between the two machine tool Y-axis longitudinal beams, and the two ends of the machine tool table crossbars are respectively fixed to the side wall of the corresponding machine tool Y-axis longitudinal beam; and machine tool table vertical bars are provided between adjacent machine tool table crossbars, and the two ends of the machine tool table vertical bars are respectively fixed to the corresponding machine tool table crossbars; the machine tool table vertical bars and machine tool table crossbars constitute a grid-like table support structure that supports the CNC engraving machine's engraving table.
[0008] In the first side machine tool column group and the second side machine tool column group, there is a machine tool column connecting square steel between adjacent machine tool columns, and the two ends of the machine tool column connecting square steel are fixed to the corresponding machine tool columns.
[0009] Its characteristics are:
[0010] The system also includes a first set of machine tool diagonal bracing groups and a second set of machine tool diagonal bracing groups. Each set of machine tool diagonal bracing groups contains several machine tool diagonal braces. One end of several machine tool diagonal braces in the first set of machine tool diagonal bracing groups is fixed to the vertical and / or horizontal rails of the machine tool table, and the other end is fixed to the square steel connecting the machine tool column on one side of the first side machine tool column group. The machine tool diagonal braces are inclined at an angle. One end of several machine tool diagonal braces in the second set of machine tool diagonal bracing groups is fixed to the vertical and / or horizontal rails of the machine tool table, and the other end is fixed to the square steel connecting the machine tool column on one side of the second side machine tool column group. The machine tool diagonal braces are inclined at an angle.
[0011] It also has two machine tool Y-axis guide rail mounting strips, which are respectively installed on the top of the corresponding machine tool Y-axis longitudinal beam.
[0012] Both the first side machine tool column group and the second side machine tool column group have 3 or 4 machine tool columns.
[0013] A connecting rod for the bottom crossbar of the machine tool is fixed between the adjacent bottom crossbars of the machine tool.
[0014] It is also equipped with a tool changer base, which is fixedly supported on at least two adjacent machine tool table crossbars on one side;
[0015] The bottom of the tool changer base is provided with a machine tool tool changer base support. The top of the machine tool tool changer base support is fixed to the tool changer base, and the bottom is fixed to the machine tool bottom crossbar connecting rod.
[0016] Two fixed, sunken funnel mounting rods are installed between the crossbars of adjacent machine tool tables near the tool changer base to place and improve the rigidity of the funnel.
[0017] A machine tool Y-axis motor mount is installed and fixed at one end of the side of the machine tool Y-axis longitudinal beam, and a machine tool Y-axis bearing mount is installed and fixed at the other end of the side of the machine tool Y-axis longitudinal beam.

[0021] This utility model has a reasonable structure. By setting multiple machine tool columns on both sides and using the machine tool table crossbars and vertical bars to form a grid-like table support structure, it can effectively distribute and bear various forces generated during the carving process. The multi-point support and grid-like structure design are similar to the frame structure in buildings, which significantly enhances the rigidity and stability of the entire support frame and reduces vibration and deformation that may occur during high-speed carving and heavy-duty processing.
[0022] This invention creatively utilizes the reinforcing function of machine tool diagonal braces. The stability of the frame is further enhanced by the arrangement of the first and second sets of machine tool diagonal braces. The diagonal braces are fixed at an inclined angle between the vertical and / or horizontal rails of the machine tool table and the connecting square steel of the machine tool column, forming a stable, triangular structure that effectively resists lateral forces and torques, ensuring the frame's stability during complex engraving tasks.
[0023] The installation of the bottom crossbar and the connecting rod of the bottom crossbar not only enhances the rigidity of the bottom, but also forms an integrated support platform by connecting the columns on both sides, further improving the stability of the entire frame.
[0024] Thanks to the high stability of the support frame, the engraving machine can maintain a high degree of stability during operation, reducing processing errors caused by vibration or shaking.
[0025] Meanwhile, in this invention, two machine tool Y-axis guide rail mounting strips are respectively installed on the top of the corresponding machine tool Y-axis longitudinal beam, providing precise guidance for the movement of the engraving head. This design ensures the accuracy of the engraving head's movement in the Y-axis direction, further improving the accuracy and stability of the engraving.
[0026] The tool changer base support ensures the stability of the tool changing process and improves the safety and efficiency of operation.
[0027] In summary, the CNC engraving machine support frame provided by this utility model, through structural optimization, enhances stability, improves processing accuracy, and extends service life, providing a strong guarantee for the efficient and stable operation of the CNC engraving machine, and has great market application and promotion value.
