[0022] A sliding platform 9 is provided on the base 1, and positioning sleeves 10 are fixedly provided at both ends of the sliding platform 9. The positioning sleeves 10 slide against the first main shaft 4;

[0023] When in use, the workpiece is fixed on the slide 9, the first spindle 4 and the second spindle 5 are inserted into the hole to be processed on the workpiece, and the boring tool 11 processes the inner wall of the hole.

[0024] Preferred as Figure 1~2 As shown, the slide 9 slides left and right against the base 1, thereby driving the workpiece to move and feed. The slide 9 is connected to the first spindle 4 through the positioning sleeve 10, which enables the workpiece and the first spindle 4 to be accurately positioned to ensure the machining accuracy of the through hole on the workpiece. The first motor 2 drives the first spindle 4 and the second spindle 5 to rotate synchronously, thereby driving the boring tool 11 to cut the workpiece. The second spindle 5 can also be adjusted up and down relative to the first spindle 4, so as to adapt to the spacing between the two through holes on the workpiece, and can process the two through holes at the same time, making the processing more efficient.

[0025] Preferably, the second motor 12 is used to drive the screw 19 to rotate, the screw 19 moves with the slide 9 through the screw sleeve, and the screw 19 rotates against the base 1 through multiple bearing seats. The second motor 12 can drive the slide 9 and the workpiece to move for feeding.

The first bearing seat 6 is also provided with a second bearing seat 7 for upward and downward sliding adjustment. The second bearing seat 7 is fixed with a threaded sleeve 16 on the side opposite to the first bearing seat 6. A threaded bidirectional screw 15 is provided between the second bearing seat 7 and the first bearing seat 6. The bidirectional screw 15 is threadedly connected to the threaded sleeve 16. The threads at both ends of the bidirectional screw 15 are in opposite directions. The rotation of the bidirectional screw 15 can drive the second bearing seat 7 and the first bearing seat 6 to move relative to adjust the spacing. A hand wheel is fixed in the middle of the bidirectional screw 15 for easy driving and rotation. Further preferably, a locking mechanism is provided between the threaded sleeve 16 and the bidirectional screw 15. The locking mechanism is a hoop type.
