The spindle mechanism 40 is located directly above the table 30 so that the spindle mechanism 40 approaches or moves away from the table 30 from above. The Z-axis transfer mechanism 70 is assembled on the gantry 20, and when the gantry 20 supports and fixedly mounts the Z-axis transfer mechanism 70, the Z-axis transfer mechanism 70 also drives the main shaft mechanism 40 to slide toward or away from the worktable 30 along the Z-axis direction. Specifically, in fig. 1, the number of the spindle mechanisms 40 is eight and is aligned in a line along the X-axis direction, so that the cnc engraving and milling machine 100 of the present invention forms an 8-axis cnc engraving and milling machine 100, that is, eight workpieces on the worktable 30 can be processed at a time; correspondingly, each main shaft mechanism 40 is provided with a corresponding Z-axis transfer mechanism 70, and each Z-axis transfer mechanism 70 drives one main shaft mechanism 40 to translate along the Z-axis direction, so that each main shaft mechanism 40 can perform independent Z-axis translation; it will be appreciated that the number of spindle mechanisms 40 may also vary from one, two, three, four or six, depending on the actual requirements.

As shown in fig. 1, 3, 4 and 5, a shielding plate 91 inclined to the rear and upward is mounted on the table 30, the shielding plate 91 is located beside the rear of the spindle mechanism 40, and the shielding plate 91 also extends in the X-axis direction to block the debris generated during the machining process of the spindle mechanism 40 from falling backward into the Y-axis transfer mechanism 60 by means of the shielding plate 91.

As shown in fig. 3, 4 and 5, the X-axis transfer mechanism 50 includes an X-axis motor 51, an X-axis lead screw 52 and an X-axis nut 53; the X-axis motor 51 is assembled in the Y-axis translation seat 65, the X-axis screw 52 is rotatably assembled in the Y-axis translation seat 65, the X-axis screw 52 is further assembled and connected with the output end of the X-axis motor 51, the X-axis screw 53 is slidably sleeved on the X-axis screw 52, and the X-axis screw 53 is further assembled and connected with the workbench 30; therefore, in the process that the X-axis motor 51 drives the X-axis lead screw 52 to rotate, the X-axis nut 53 is driven to translate along the X-axis direction together with the worktable 30, so as to meet the requirement of X-axis translation of the worktable 30. Since the X-axis motor 51 is assembled in the Y-axis translation seat 65 and the X-axis screw 52 is rotatably assembled in the Y-axis translation seat 65, the scraps in the process are effectively prevented from falling to the X-axis motor 51, the X-axis screw 52 and the X-axis screw nut 53 to influence the working reliability of the X-axis motor 51, the X-axis screw 52 and the X-axis screw nut 53.

The X-axis direction is the left-right direction of the base 10, the Y-axis direction is the front-back direction of the base 10, and the Z-axis direction is the up-down direction of the base 10; in the X-axis transfer mechanism 50, the X-axis nut 53 forms an output end of the X-axis transfer mechanism 50, and in the Y-axis transfer mechanism 60, the Y-axis translation seat 65 forms an output end of the Y-axis transfer mechanism 60; in addition, when the Y-axis transfer mechanism 60 is assembled on the base 10, the Y-axis transfer mechanism 60 can drive the X-axis transfer mechanism 50 and the worktable 30 to perform a large-scale translation along the Y-axis direction, and the X-axis transfer mechanism 50 is limited by the gantry 20 and can only perform a small-scale translation along the X-axis direction, so the size of the cnc engraving and milling machine 100 of the present invention along the X-axis direction is designed to be smaller.
