An assembly plate 3 is fixedly connected to the rear side wall of the machining table 9. The assembly plate 3 is slidably connected to the machining table 9. A Y-axis servo motor is assembled between the assembly plate 3 and the machining table 9.

[0023] The Z-axis servo motor 1, X-axis servo motor 2 and Y-axis servo motor in this technical solution are all common motor drive devices on the market, so they are not described in detail in this technical solution. The Z-axis servo motor 1 has a braking function, which can better protect the safe use of the equipment.

[0024] As Figures 1 - 4 shown, the tool magazine mechanism includes tool magazine linear guides 8. Two tool magazine linear guides 8 are provided and are respectively installed on the top of the assembly plate 3. A support frame 7 is arranged above the two tool magazine linear guides 8. The support frame 7 is slidably connected to the tool magazine linear guides 8. A tool holder 6 is assembled on the top of the support frame 7. A number of evenly distributed placement grooves 16 are arranged on the top of the tool holder 6. Six placement grooves 16 are provided. A tool magazine cylinder 5 is installed between one side of the support frame 7 and the top of the assembly plate 3.

[0025] Through the tool magazine mechanism, six different types of tools can be configured for engraving use. Through the tool magazine cylinder 5, the tool holder 6 can be pushed to a suitable position to cooperate with the automatic tool change spindle 4 to pick up and place tools.

[0026] Among them, the support frame 7 is arranged in a U shape. A chute matching the linear guide rail 8 of the tool magazine is provided at the sliding connection between the bottom of the support frame 7 and the linear guide rail 8 of the tool magazine. Through the chute, the support frame 7 can slide stably in a straight line on the assembly plate 3, avoiding displacement and tilting phenomena.

[0027] In addition, the cast iron gantry 11 is integrally arranged in a U shape and spans across the processing table 9 and the assembly plate 3. The support legs of the cast iron gantry 11 are arranged in a triangular shape. The U-shaped cast iron gantry 11 is more stable to use and will not shake. Its triangular support legs can increase its stability and at the same time increase the processing space, making it more convenient to use.

[0028] Among them, a first slider is fixedly connected to the bottom of the mounting frame 12, and a transverse slide rail matching the first slider is fixedly connected to the top of the cast iron gantry 11.

[0029] In addition, second sliders are installed in a buttressing manner at the bottoms of the processing table 9 and the assembly plate 3, and linear slide rails matching the second sliders are symmetrically installed on the top of the cast iron base 10. Through the second sliders and the linear slide rails, the processing table 9 and the assembly plate 3 can operate more smoothly and precisely without noise.

[0030] Working principle: When using this technical solution, first place the engraving machine in a suitable horizontal position and place the tools to be used in the placement groove 16. Next, when the engraving machine is needed, power it on. During engraving, computer programming can be carried out according to needs. Among them, the X-axis servo motor 2 can drive the mounting frame 12, the lifting plate 14 and the automatic tool change spindle 4 to displace left and right, and the Z-axis servo motor 1 can drive the X-axis servo motor 2 and the automatic tool change spindle 4 to displace up and down. At the same time, the Z-axis servo motor 1 has a braking function. In addition, the Y-axis servo motor installed at the bottom of the assembly plate 3 can drive the processing table 9 and the cast iron base 10 to displace back and forth, so that the metal workpiece can be displaced back and forth. After programming, the tool magazine cylinder 5 pushes the support frame 7 and the tool holder 6 forward. The automatic tool change spindle 4 is controlled by the X-axis servo motor 2 and the Z-axis servo motor 1 to descend and pick up one of the tools. After picking up, the tool magazine cylinder 5 will pull the support frame 7 and the tool holder 6 back to the rear side to avoid affecting engraving. Next, the automatic tool change spindle 4 is moved by controlling the Z-axis servo motor 1 and the X-axis servo motor 2 to process the metal workpiece. After processing, the tool magazine cylinder 5 pushes the support frame 7 forward, and the automatic tool change spindle 4 descends to place the tool in the empty placement groove 16 and returns to the initial position. Then the tool magazine cylinder 5 pulls the support frame 7 back to the initial position, effectively solving the problem of poor engraving efficiency.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementation schemes of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
