Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tools, in particular to a four-axis dragon column engraving machine. Background Art

[0002] In the process of dragon column processing, rough processing and fine processing are two crucial links. In the rough processing stage, the dragon column is initially cut and carved by a high-speed rotating saw blade, so that the shape and outline of the dragon column gradually emerge. The fine processing stage is more delicate and complex. A carving knife is needed to carve and modify the surface of the dragon column in detail.

[0003] However, in the current processing, rough processing and fine processing need to be performed on different machine tools respectively, which not only leads to low processing efficiency but also increases a lot of costs. Utility Model Content

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0021] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] 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 technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0023] Reference Figure 1-Figure 3 This embodiment discloses a four-axis dragon column engraving machine, whose structure includes a machine base, and the machine base is provided with two side panels 1 arranged at intervals. The two ends of the two side panels 1 are connected to each other by a connecting rod 2, so that a workstation for processing is formed between the two side panels 1. Between the two side panels 1, a clamping device 8 for clamping the dragon column 7 is provided. Since the machine base of the traditional engraving machine is welded as a whole, it is inconvenient during transportation and assembly. The present application adopts two side panels 1 and connecting rods 2 to be detachably assembled into a machine base, and the machine base can be disassembled into several parts, fixed and packaged into independent parts for easy transportation. After being transported to the site, it can be assembled, which is convenient for the disassembly and transportation of the entire machine base. Therefore, customers can customize large-scale processing equipment according to their needs, and easily load it into the container through disassembly, which is convenient for export.

[0024] The clamping device 8 is mainly composed of a base 81, a spindle box 82 and an ejector box 83 arranged on the base 81. The function of the spindle box 82 and the ejector box 83 is to clamp the dragon column 7 and enable it to rotate. More specifically, the inner sides of the spindle box 82 and the ejector box 83 are equipped with ejectors that contact the dragon column 7. A motor is also arranged in the spindle box 82, and the motor can drive the dragon column 7 to rotate. A commonly used rotation drive structure is adopted here, and the specific rotation principle is well known to technicians in this field, so it will not be described in detail in this embodiment.

[0025] A slidable crossbeam 3 is also provided on the machine base. Both ends of the crossbeam 3 are driven by a gear rack mechanism. This transmission mode can also be achieved by other transmission mechanisms such as a screw rod and an electric cylinder. In this embodiment, a gear rack mechanism is preferred. The motor drives the gear to rotate, and then cooperates with the rack to achieve the sliding of the crossbeam 3 on the machine base.

[0026] A slidable machine head 4 is also provided on the cross beam 3, and the machine head 4 slides with the cross beam 3 via a gear rack mechanism. A cutting device 5 and an engraving device 6 are provided on the machine head 4. It is worth noting that the engraving device 6 and the cutting device 5 are located on different sides of the cross beam 3, so that the synchronous processing of cutting and engraving can be achieved, thereby greatly improving the efficiency.

[0027] The cutting device 5 mainly includes a first lifting mechanism disposed on the crossbeam 3 and a saw blade 51 disposed at the bottom end of the first lifting mechanism. The engraving device 6 includes a second lifting mechanism disposed on the crossbeam 3 and an engraving knife 61 disposed at the bottom end of the second lifting mechanism. Both the first lifting mechanism and the second lifting mechanism are driven by ball screws, thereby realizing the lifting function of the saw blade 51 and the engraving knife 61.

[0028] In addition, dust covers 9 are provided on the two side panels 1, the crossbeam 3, the first lifting mechanism and the second lifting mechanism to prevent dust. The saw blade 51 and the engraving tool 61 are lifted and lowered by the first lifting structure and the second lifting structure, and the machine head 4 is moved by the gear rack mechanism, and the saw blade 51 and the engraving tool 61 are moved on the crossbeam 3 along the X axis. The crossbeam 3 slides on the machine base through the gear rack to move the saw blade 51 and the engraving tool 61 along the Y axis. The dragon column 7 rotates on the clamping device 8 to realize four-axis linkage. In the whole process, it is guided by linear guides and driven by servo motors, and the operation is stable and the precision is higher.

[0029] More importantly, the cutting device 5 and the carving device 6 can perform rough processing and fine processing on the dragon column 7. Rough processing and fine processing can be completed by one device, which not only improves processing efficiency, but also reduces costs.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
