[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a dual-axis boring mechanism includes a base 1, two parallel protrusions are arranged on both sides of the upper side of the base 1, and two slide rails 2 are respectively installed on the two protrusions. A U-shaped slide plate 3 is slidably connected to the upper side of the slide rail 2. A screw motor 8 and a screw 9 are also installed on the upper side of the base 1, and the screw motor 8 and the screw 9 are both located between the two protrusions. The output end of the screw motor 8 is connected to one end of the screw 9, and a screw sleeve is fixed on the U-shaped slide plate 3, and the screw sleeve is arranged on the outside of the screw 9. When the screw motor 8 rotates, it drives the screw 9 to rotate, and when the screw 9 rotates, it drives the U-shaped slide plate 3 to move along the slide rail 2.

[0021] A rotating shaft mounting frame 5 is fixed on the upper side of the U-shaped slide 3, a motor bracket 6 is fixedly mounted on the end surface of the rotating shaft mounting frame 5, and a spindle motor 7 is fixedly mounted on the motor bracket 6. Two rotating shafts parallel to each other are mounted inside the rotating shaft mounting frame 5, and both ends of the rotating shafts pass through the rotating shaft mounting frame 5. A boring tool clamping unit 10 is mounted at one end of the rotating shaft, and the boring tool clamping unit 10 is used to clamp and fix a boring tool 13. A driving wheel 11 is mounted on the output shaft of the spindle motor 7, and two driven wheels 12 are arranged on the lower side of the driving wheel 11. The two driven wheels 12 are respectively mounted on two rotating shafts, and a belt is connected between the driving wheel 11 and the two driven wheels 12. When the spindle motor 7 rotates, it drives the driving wheel 11 to rotate, and drives the two driven wheels 12 to rotate through the belt, thereby driving the two rotating shafts to rotate, and then the two boring tools 13 rotate synchronously.

[0022] The shaft mounting frame 5 is fixedly mounted on the top of the U-shaped slide 3 by bolts. During installation or later maintenance, in order to facilitate accurate and rapid installation of the shaft mounting frame 5, positioning blocks 14 are fixed on the top of both sides of the U-shaped slide 3, and positioning grooves 15 are provided on the top of the positioning blocks 14. Positioning pins 16 are fixed at both ends of the shaft mounting frame 5, and the width of the positioning grooves 15 is the same as the cross-sectional diameter of the positioning pins 16. During installation, the positioning pins 16 are first inserted into the positioning grooves 15 to ensure installation accuracy, and then the bolts are tightened.

[0023] In order to prevent iron filings and other debris from adhering to the slide rail 2, the protrusion and the slide rail 2 are both located on the inner side of the U-shaped slide plate 3, and a guide plate 4 is fixedly connected to the front end of the U-shaped slide plate 3. The guide plate 4 is located on the lower side of the two boring cutters 13, and the top of the guide plate 4 is inclined. The cross section of the guide plate 4 is "U"-shaped. The protrusion and the slide rail 2 are both located on the inner side of the guide plate 4, and the side of the guide plate 4 is flush with the side of the U-shaped slide plate 3. During the movement of the U-shaped slide plate 3, the debris always falls on the inclined guide plate 4, and the side guards of the U-shaped slide plate 3 and the guide plate 4 play a certain protective role on the slide rail, which can prevent the debris from entering the internal space and adhering to the slide rail.
