[0028] The lifting mechanism 2 is installed on the moving end of the transverse moving mechanism 3; the machining head 9 is installed on the moving end of the lifting mechanism 2. The transverse movement and lifting of the machining head 9 are provided by the transverse moving mechanism 3 and the lifting mechanism 2 respectively. The object is placed on the workbench and engraved by the machining head 9 above the workbench.

[0029] Embodiment 1:

[0030] Reference Figure 1 The engraving machine of the embodiment improves the existing three-dimensional engraving machine; a rotary table 5 is arranged on the upper surface of the workbench, the rotary table 5 is rotated by the motor to rotate around its own central axis, and the object to be engraved is placed on the rotary table 5, so that it can not only be engraved from top to bottom but also be engraved laterally. In order to realize this function, the lifting mechanism 2 is mainly improved technically, and the specific improvements are as follows:

[0031] Referring to Figure 2 and Figure 5 In this embodiment, the lifting mechanism 2 includes a lifting column, a lifting screw 20 and a rotating nut 18, the lifting column 6 and the lifting screw 20 are arranged in parallel; on the left side of the lifting column 6: both ends of the lifting screw 20 are fixedly installed on the lifting column 6; the lifting motor and the rotating nut 18 threaded with the lifting screw 20 are both installed on the action end of the horizontal moving mechanism 3, wherein the rotating nut 18 is connected with the action end bearing of the horizontal moving mechanism 3.

[0032] The lifting motor drives the rotating nut 18 to rotate, the rotating nut 18 is threaded with the lifting screw 20 and is constrained by the first lifting guide rail slidingly matched with the action end of the horizontal moving mechanism 3, so that the lifting screw 20 and the lifting column 6 perform lifting movement.

[0033] Referring to Figure 5 and Figure 4 On the right side of the lifting column 6, the opposite side of the lifting screw 20, a second lifting guide rail 7 is also arranged, the second lifting guide rail 7 is parallel to the first lifting guide rail; the second lifting guide rail 7 is provided with a mounting plate slidingly matched therewith.

[0034] Referring to Figure 3 The main body of the pitching mechanism is a pitching turntable 16, the pitching turntable 16 is arranged in parallel with the mounting plate and is rotationally connected; the machining head 9 is installed on the pitching turntable 16. The pitching turntable 16 rotates to realize the rotation of the engraving angle of the machining head 9, and when the machining head 9 is vertically downward, the machining object top is processed, and when the machining head 9 is oriented to one side, the machining object side is processed.

[0035] In this embodiment, two schemes are respectively proposed to complete the lifting of the mounting plate (the height of the machining head 9) and the rotation of the pitching turntable 16 (the orientation of the machining head 9).

[0036] Firstly, the lifting of the mounting plate:

[0037] A plurality of mounting plate locking holes 8 arranged vertically are arranged on the lifting column 6 or the second lifting guide rail 7; and a pin hole is arranged on the mounting plate. The pin hole and one of the mounting plate locking holes 8 are opposite and locked by the pin; when the height needs to be adjusted, the mounting plate locking hole 8 is switched, the pin hole is opposite to the corresponding mounting plate locking hole 8, and then the pin is locked, so that the height of the machining head 9 is finally adjusted in multiple stages.

[0038] Secondly, the rotation of the pitching turntable 16:

[0039] The mounting plate is provided with a circular groove at the end, the center of the circular groove coincides with the center of the pitch rotary disc 16; the cross section of the circular groove is T-shaped; the head of the locking bolt is installed in the circular groove, and the locking bolt can slide along the circular groove; the pitch rotary disc 16 is provided with a locking hole; the other end of the locking bolt passes through the locking hole and is locked by a locking nut. When the pitch rotary disc 16 needs to be rotated, the locking nut is loosened, the locking bolt is driven to move along the circular groove by manpower, and the pitch rotary disc 16 is rotated together to reach the appropriate angle, and then the nut is tightened to achieve locking. Therefore, the stepless adjustment of the rotation of the pitch rotary disc 16 is realized.

The output shaft of the adjusting motor rotates to drive the rotation of the adjusting screw rod 19, and since the mounting plate is constrained on the second lifting guide rail 7, the mounting plate is lifted and moved by the adjusting screw rod 19, and the self-locking function is realized by the adjusting screw rod 19, so that the lifting adjustment does not need to be driven by manpower.

[0044] The rotation of the pitch rotary disc 16 is as follows:

[0045] The pitch rotary disc 16 is provided with a gear or a belt pulley, which is driven to rotate by the pitch motor installed on the mounting plate. The pitch motor has a self-locking function.

[0049] The guide groove and the screw rod are arranged in parallel, the sliding block is threadedly connected with the screw rod and is in sliding fit with the guide groove; the screw rod is driven to rotate by the screw rod motor.

[0050] The guide groove and the screw rod of the longitudinal moving mechanism 1 are both mounted on the left stand, wherein the screw rod is connected with the left stand bearing; the right stand is provided with a longitudinal sliding rail;
