Description

Technical Field

[0001] This utility model relates to the field of engraving machine technology, specifically to a five-axis engraving machine structure. Background Technology

[0002] A five-axis CNC engraving machine, as the name suggests, refers to a machine tool with at least five coordinate axes: three linear axes (X, Y, Z) and two rotary axes. This type of machine tool is often called a "3+2 axis" machine tool, which is a combination of three linear axes and two rotary axes.

[0003] A five-axis CNC engraving machine achieves precise machining of workpieces through the coordinated movement of five coordinate axes. Three linear coordinate axes (X, Y, Z) are responsible for positioning the workpiece in three-dimensional space, while the two rotary coordinate axes are responsible for adjusting the tool's orientation to adapt to the machining requirements of complex curved surfaces. During machining, the tool can move along complex paths, thus achieving high-precision machining of the workpiece. However, for machining small parts, if the above method is used, the tool's movement along complex paths requires a large amount of space, resulting in low space utilization and inconvenience for tool changes. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a five-axis engraving machine structure.

[0005] The objective of this utility model is achieved through the following technical solution: a five-axis engraving machine structure, comprising a machine base, a crossbeam connected to the top of the machine base, an X-axis linear module connected to one side of the crossbeam, a Z-axis linear module connected to the output end of the X-axis linear module, a spindle box connected to the output end of the Z-axis linear module, a spindle connected to the spindle box, a Y-axis linear module connected to the top of the machine base, a five-axis rotary table connected to the output end of the Y-axis linear module, a rotary seat connected to the side of the machine base away from the five-axis rotary table, and a tool magazine assembly connected to the output end of the rotary seat. The spindle is used to drive the tool to rotate, the output end of the five-axis rotary table is used to fix and cooperate with the machining fixture, and the rotary seat is used to drive the tool magazine assembly to rotate and position at any angle.

[0006] Preferably, the rotary base includes a fixed frame connected to the side of the machine tool away from the five-axis rotary table, and a hollow rotary platform connected to the top of the fixed frame, the output end of which is fixedly connected to the tool magazine assembly.

[0007] Preferably, the tool magazine assembly includes a circular tool disc fixedly connected to the output end of the rotary base, and multiple pairs of tool grippers distributed in annularly on the circular tool disc, the tool grippers being used to hold the tools.

[0008] Preferably, each pair of tool grippers has a protruding tab on its inner side for engaging with the tool.

[0009] Preferably, the machine tool has a waste liquid discharge port in the middle and a waste liquid tank placement trough communicating with the waste liquid discharge port at the bottom.

[0010] Preferably, the five-axis rotary table includes a first rotary table connected to the output end of the Y-axis linear module and capable of rotating around the X-axis in the A-axis direction, and a second rotary table connected to the output end of the first rotary table and capable of rotating around the Z-axis in the C-axis direction. The output end of the second rotary table is used to fix and cooperate with the machining fixture.

[0011] The beneficial effects of this utility model are as follows: The five-axis engraving machine structure of this utility model adopts a machine base, a crossbeam connected to the top of the machine base, an X-axis linear module connected to one side of the crossbeam, a Z-axis linear module connected to the output end of the X-axis linear module, a spindle box connected to the output end of the Z-axis linear module, a spindle connected to the spindle box, a Y-axis linear module connected to the top of the machine base, a five-axis rotary table connected to the output end of the Y-axis linear module, a rotary seat connected to the side of the machine base away from the five-axis rotary table, and a tool magazine assembly connected to the output end of the rotary seat. In use, the machining fixture holding the workpiece to be processed is placed at the output end of the five-axis rotary table. The system utilizes X-axis and Z-axis linear modules to drive the spindle box and spindle, moving the tool along the XZ axis. The five-axis rotary table drives the machining fixture, causing the workpiece to rotate around the X-axis (A-axis) and around the Z-axis (C-axis). The Y-axis linear module drives the five-axis rotary table to move along the Y-axis. In other words, the tool moves along the XZ axis, the workpiece moves along the Y-axis and rotates along the AC axis. This results in a more compact structure, improved space utilization, and suitability for machining small parts. The rotary table drives the tool magazine assembly to rotate and position at any angle, allowing the spindle to move along the XZ axis to cooperate with the rotary table and tool magazine assembly for tool changing.

[0015] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0016] like Figure 1-2 As shown, a five-axis engraving machine structure includes a machine base 1, a crossbeam 2 connected to the top of the machine base 1, an X-axis linear module 3 connected to one side of the crossbeam 2, a Z-axis linear module 4 connected to the output end of the X-axis linear module 3, a spindle box 5 connected to the output end of the Z-axis linear module 4, a spindle 6 connected to the spindle box 5, a Y-axis linear module 7 connected to the top of the machine base 1, a five-axis rotary table 8 connected to the output end of the Y-axis linear module 7, a rotary seat connected to the side of the machine base 1 away from the five-axis rotary table 8, and a tool magazine assembly 10 connected to the output end of the rotary seat. The spindle 6 is used to drive the tool to rotate, the output end of the five-axis rotary table 8 is used to fix and cooperate with the machining fixture, and the rotary seat is used to drive the tool magazine assembly 10 to rotate and position at any angle.

[0017] In this five-axis engraving machine, the machining fixture holding the workpiece is placed at the output end of the five-axis rotary table 8. The spindle box 5 and spindle 6 are driven by the X-axis linear module 3 and the Z-axis linear module 4, which move the tool along the XZ axis. The five-axis rotary table 8 drives the machining fixture, which rotates the workpiece around the X-axis (A-axis) and around the Z-axis (C-axis). The Y-axis linear module 7 drives the five-axis rotary table 8 to move along the Y-axis. That is, the tool moves along the XZ axis, the workpiece moves along the Y-axis and rotates along the AC axis. The structure is more compact and improves space utilization. It is more suitable for processing small parts. The rotary table drives the tool magazine assembly 10 to rotate and position at any angle so that the spindle 6 can move along the XZ axis to cooperate with the rotary table and tool magazine assembly 10 for tool changing.

[0018] Furthermore, the rotating base includes a fixed frame 91 connected to the side of the machine base 1 away from the five-axis rotary table 8, and a hollow rotating platform (not shown in the figure) connected to the top of the fixed frame 91.

[0019] Furthermore, the tool magazine assembly 10 includes a circular tool disc 101 fixedly connected to the output end of the rotary base, and multiple pairs of tool grippers 102 arranged in a ring on the circular tool disc 101, the tool grippers 102 being used to hold tools. The rotary base drives the circular tool disc 101 to rotate to any angle for positioning, so that the spindle 6 can change tools.

[0020] Furthermore, each pair of tool grippers 102 has a protruding tab 11 on its inner side for engaging with the tool. In actual use, the tool has an annular groove 12 that engages with the tab 11. When the spindle 6 unloads the tool, the rotary seat drives the circular tool disc 101 to rotate to the tool changing position. The spindle 6 drives the tool to move laterally so that the tool moves to the unloaded tool gripper 102 and the tab 11 engages with the annular groove 12. The spindle 6 then releases the tool and moves upward to complete the tool unloading operation of the spindle 6.

[0021] Furthermore, a waste liquid discharge port 13 is provided in the middle of the machine platform 1, and a waste liquid tank placement trough 14 communicating with the waste liquid discharge port 13 is provided at the bottom of the machine platform 1.

[0022] Furthermore, the five-axis rotary table 8 includes a first rotary table 81 connected to the output end of the Y-axis linear module 7 and capable of rotating around the X-axis (A-axis), and a second rotary table 82 connected to the output end of the first rotary table 81 and capable of rotating around the Z-axis (C-axis). The output end of the second rotary table 82 is used for fixed engagement with a machining fixture. Specifically, the output end of the second rotary table 82 has a plurality of screw holes 15 arranged in a ring for fixed engagement with the machining fixture.
