[0028] In the related art, the tool magazine is usually jointly arranged on the y-axis translation carrier with the spindle, and then the y-axis translation carrier is arranged on the x-axis translation carrier, so that the tool magazine and the spindle can move synchronously in the x-axis direction and the y-axis direction. In this way, the driving mechanism in the y-axis direction needs to bear the loads of the tool magazine and the spindle, resulting in an excessive load, which is likely to affect the machining accuracy and service life.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 is a three-dimensional structural schematic diagram of a novel three-axis machining tool 100 provided by an embodiment of an implementation manner of the present utility model; Figure 2 is Figure 1 a three-dimensional structural schematic diagram of the novel three-axis machining tool 100 from another perspective. The implementation manner of the present utility model provides a novel three-axis machining tool 100. The novel three-axis machining tool 100 includes a frame 10, an x-axis translation carrier 20, a y-axis translation carrier 30, a spindle 40, a tool magazine 50, and a workbench 60. The frame 10 is used to be arranged on a support surface. The x-axis translation carrier 20 is arranged on the frame 10 and can move relative to the frame 10 in the x-axis direction. The y-axis translation carrier 30 is arranged on the x-axis translation carrier 20 and can move relative to the x-axis translation carrier 20 in the y-axis direction. The spindle 40 is arranged on the y-axis translation carrier 30 and can move relative to the y-axis translation carrier 30 in the z-axis direction. The tool magazine 50 is arranged on the x-axis translation carrier 20 and is used for changing tools for the spindle 40. The workbench 60 is arranged on the frame 10 and is used for carrying workpieces.

[0030] Specifically, the machine frame 10 is used to be set on a support surface such as the ground or the surface of other equipment. Preferably, the machine frame 10 is used to be set on the ground, that is, the bottom surface of the machine frame 10 fits the ground. It should be noted that the x-axis direction, y-axis direction, and z-axis direction are perpendicular to each other pairwise. The tool magazine 50 is configured with multiple tools, and the corresponding tool can be replaced onto the spindle 40 according to the processing requirements. The spindle 40 can drive the tool to rotate around the z-axis direction and move the carrier along the z-axis direction relative to the y-axis to approach the workpiece, so that the tool contacts the workpiece for processing.

[0031] By setting the tool magazine 50 on the x-axis translation carrier 20, the tool magazine 50 can move relative to the machine frame 10 along the x-axis direction following the y-axis translation carrier 30 and the spindle 40. The tool magazine 50 is always located near the spindle 40, which is convenient for the tool magazine 50 to change tools. At the same time, the y-axis translation carrier 30 only drives the spindle 40 to move along the y-axis direction, and the load of the driving mechanism in the y-axis direction is small, which is beneficial to improving the processing accuracy and service life.

[0032] In an embodiment of this implementation manner, please refer to Figure 1 and Figure 2 , the machine frame 10 includes a connected first part 11 and second part 12. In the z-axis direction, the first part 11 has a higher height relative to the second part 12. The x-axis translation carrier 20 is slidably arranged on the first part 11, and the workbench 60 is arranged on the second part 12. With such a setting, it is convenient for the spindle 40 to have a higher height relative to the workbench 60 in the z-axis direction, and the spindle 40 can move to the top side of the workpiece on the workbench 60 to process the workpiece.

[0033] In an embodiment of this implementation manner, please refer to Figure 1 and Figure 2 , the new type three-axis processing machine tool 100 includes a mounting frame 21.

Specifically, the mounting frame 21 is bent. One end of the mounting frame 21 is fixed on the x-axis translation carrier 20 by screws, and the other end of the mounting frame 21 is fixed to the side of the tool magazine 50 by screws. It can be understood that the other end of the mounting frame 21 can extend to the top side of the second part 12, so that the spindle 40 can complete the tool change action on the top side of the workbench 60, and there is no need for the spindle 40 to move significantly before tool change, which is beneficial to improving the processing efficiency.

[0034] In an embodiment of this implementation manner, please refer to Figure 1 and Figure 2, the frame 10 is provided with an x-axis slide rail 13, and the x-axis translation carrier 20 is slidably engaged with the x-axis slide rail 13. Both ends of the x-axis slide rail 13 protrude from the two side surfaces of the frame 10 in the x-axis direction. Specifically, the number of x-axis slide rails 13 is two, and the two x-axis slide rails 13 are arranged at intervals and in parallel, and the x-axis slide rail 13 extends in the x-axis direction. It can be understood that by providing the x-axis slide rail 13, it is beneficial to improve the movement accuracy of the x-axis translation carrier 20 relative to the frame 10 in the x-axis direction. Both ends of the x-axis slide rail 13 protrude from the two side surfaces of the frame 10 in the x-axis direction, so that the x-axis translation carrier 20 can slide a greater stroke relative to the frame 10, facilitating the machining of large-sized workpieces.

Specifically, the number of y-axis slide rails 31 is two, and the two y-axis slide rails 31 are arranged at intervals and in parallel, and the y-axis slide rail 31 extends in the y-axis direction. It can be understood that by providing the y-axis slide rail 31, it is beneficial to improve the movement accuracy of the y-axis translation carrier 30 relative to the x-axis translation carrier 20 in the y-axis direction. At the same time, the end of the y-axis slide rail 31 away from the main shaft 40 protrudes from the side surface of the y-axis translation carrier 30 facing away from the main shaft 40 in the y-axis direction, so that the y-axis translation carrier 30 can have a greater stroke relative to the x-axis translation carrier 20 in the y-axis direction away from the workbench 60.

Specifically, the number of z-axis slide rails 41 is two, and the two z-axis slide rails 41 are arranged at intervals and in parallel, and the z-axis slide rail 41 extends in the z-axis direction. It can be understood that by providing the z-axis slide rail 41, it is beneficial to improve the movement accuracy of the main shaft 40 relative to the y-axis translation carrier 30 in the z-axis direction. At the same time, the end of the z-axis slide rail 41 away from the workbench 60 protrudes from the side surface of the main shaft 40 away from the workbench 60 in the z-axis direction, so that the main shaft 40 can have a greater stroke relative to the y-axis translation carrier 30 in the z-axis direction away from the workbench 60.

[0037] In an embodiment of this embodiment, please refer to Figure 1 and Figure 2, the machine frame 10 is provided with a guiding inclined plane 101, and the workbench 60 is located on the top side of the guiding inclined plane 101. Specifically, the guiding inclined plane 101 is located in the second part 12 and forms a certain angle with the horizontal plane (the plane parallel to the x-axis direction and the y-axis direction). The guiding inclined plane 101 has two side edges in the y-axis direction, and the side edge closer to the first part 11 has a higher height (in the z-axis direction) relative to the side edge farther from the first part 11 with respect to the supporting surface. Such a setting facilitates the discharge of waste materials such as waste chips after processing along the guiding inclined plane 101, which is beneficial to improving the processing efficiency.
