[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] The following is for reference Figures 1 to 4 The embodiments of this utility model are described below:

[0027] A self-cleaning CNC engraving machine, such as Figure 1 , Figure 2 As shown, the device includes a fixedly connected support base 10 and support beam 11. The support base 10 is equipped with a worktable 12 that can move back and forth, and the support beam 11 is equipped with a box 13 that can move left and right. A liftable base 20 is slidably connected inside the box 13. The base 20 is fixed with a spindle 40 and a cooling and cleaning assembly 30. The spindle 40 is used to drive the engraving cutter 41. The cooling and cleaning assembly 30 includes a liftable and rotatable liquid storage tray 301. The liquid storage tray 301 is connected to a spray head 302 and a liquid inlet hose 303. The spindle 40 and the spray head 302 are located above the worktable 12.

[0028] The rear of the base 20 is screwed onto a vertically arranged screw 21. Both ends of the screw 21 are rotatably connected to the housing 13. One end of the screw 21 is provided with a first servo motor that drives it to rotate. The first servo motor is fixed inside the housing 13 and electrically connected to the controller.

[0029] The base 20 is slidably connected to the vertically arranged guide rail 22, and the guide rail 22 is fixed inside the housing 13;

[0030] The linear module is fixed inside the supporting beam, and the box 13 is fixed on the slider of the linear module.

[0031] like Figure 2 , Figure 3 As shown, the cooling and cleaning assembly 30 in this embodiment also includes a lifting column 304, and the liquid storage tray 301 is connected to the lower end of the lifting column 304;

[0032] The middle part of the lifting column 304 is inserted into the guide sleeve 305, and the guide sleeve 305 is fixed on the base 20;

[0033] The upper end of the lifting column 304 is connected to the telescopic rod of the vertically arranged telescopic cylinder 306, and the telescopic cylinder 306 is fixed on the base 20.

[0034] The lower end of the lifting column 304 is rotatably connected to a support shaft 307. The liquid storage tray 301 is fixed to the rear end of the support shaft 307. The front end of the support shaft 307 is fixed to a worm gear 308. The worm gear 308 meshes with a worm 309. The worm 309 is connected to a second servo motor 310 that drives it to rotate. The second servo motor 310 is fixed on the lifting column 304 and electrically connected to the controller. The worm 309 is rotatably connected to the lifting column 304.

[0035] The lifting column 304 has a power groove 311 formed on it, and the second servo motor 310, worm gear 309 and worm wheel 308 are placed in the power groove 311.

[0036] The lifting column 304 extends through the upper end of the guide sleeve 305 to form a limit stop 312. The stop is used to limit the downward movement of the lifting column and prevent it from moving too far down and hitting the worktable.

[0037] Working principle: When performing fine carving, the template workpiece is fixed on the worktable, and the worktable can drive the template workpiece to move back and forth; the linear module can drive the housing to move left and right, thereby realizing the left and right movement of the spindle; the first servo motor drives the screw to rotate, and the screw drives the base to move up or down, thereby realizing the lifting and lowering of the spindle; the spindle can drive the fine carving cutter to rotate, thereby realizing the fine carving cutter to carve on the template workpiece.

[0038] During the engraving process, the spray nozzle faces the engraving tool, and the cutting fluid enters the reservoir through the inlet pipe. Then, the cutting fluid in the reservoir is sprayed from the spray nozzle onto the engraving tool, thereby lubricating and cooling the template workpiece and the engraving tool.

[0039] When the workbench needs cleaning, the second servo motor drives the worm gear to rotate, which in turn drives the worm wheel. The worm wheel, through a support shaft, drives the liquid reservoir to rotate, which in turn drives the spray nozzle to rotate, spraying cutting fluid onto the workbench in a specific direction. Combined with the forward and backward movement of the workbench and the left and right movement of the housing, the cleaning process is completed automatically. Simultaneously, a telescopic cylinder can raise and lower the lifting column, thereby adjusting the height of the spray nozzle to accommodate cleaning and cooling operations under different conditions.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
