Just align the center of the central hole 10 with the drilling position on the workpiece, and then screw the locking nut onto the threaded rod 9. That is, the workpiece is positioned through the positioning assembly 7 and the cover plate 8. Then, after rotating the drill bit 3, the workpiece can be drilled.

[0028] In order to accurately position the workpiece placed on the supporting plate 4, a positioning stop rod 12 is provided on the cover plate 8. The positioning stop rod 12 is located on the side of the central hole. A positioning rod 13 is also provided on the cover plate 8. The positioning rod 13 includes a vertical rod 14.

A positioning screwing rod 17 is provided in the sleeve 16. The positioning screwing rod 17 is screwed in the sleeve 16. Rotate the cross rod 15. When the cross rod 15 contacts the positioning stop rod 12, the positioning screwing rod cannot continue to reverse and move. At this time, the center of the central hole 10 is located on the extension line of the central axis of the positioning screwing rod 17. Align the positioning screwing rod with the drill bit. At this time, move the workpiece located between the supporting plate 4 and the cover plate 8 so that the intersection point of the lines drawn on the workpiece contacts the bottom end of the positioning screwing rod 17. That is, the pre-positioning of the workpiece on the supporting plate 4 is completed. At this time, screw the locking nut on the threaded rod 9 so that the cover plate 8 contacts the workpiece. The workpiece is clamped between the supporting plate 4 and the cover plate 8, and the fixing of the workpiece on the supporting plate 4 can be completed.

[0029] In order to reduce the workload of the staff, when drilling the same batch of workpieces, it is not necessary to pre-scratch and pre-position the drilling points of each workpiece except the first one. A positioning component 7 is provided on the supporting plate 4. The positioning component 7 includes an X-axis positioning block 18. The X-axis positioning block 18 is arranged along the length direction of the supporting plate 4. There is a gap between the X-axis positioning block 18 and the supporting plate 4. A positioning slider 19 is arranged below the X-axis positioning block 18. There are two positioning sliders 19, and the positioning sliders 19 are symmetrically arranged on the lower surface of the X-axis positioning block 18. A positioning chute 20 is provided on the supporting plate 4. The positioning slider 19 is located in the positioning chute 20. There are also two positioning chutes 20. The length direction of the positioning chute 20 is perpendicular to the length direction of the X-axis positioning block 18. The X-axis positioning block 18 moves on the supporting plate 4 along the length direction of the positioning chute 20, and the position of the workpiece in the Y-axis direction on the supporting plate 4 can be determined. In order to fix the position of the X-axis positioning block 18 on the supporting plate 4, a locking rod 21 is fixed on the lower surface of the positioning slider 19. A positioning notch 22 matching the locking rod 21 is arranged in the positioning chute 20. The positioning notch 22 extends along the length direction of the positioning chute 20. The positioning notch 22 is also located on the supporting plate 4. The positioning notch 22 penetrates through the supporting plate 4. The locking rod 21 is located in the positioning notch 22. The locking rod 21 can slide in the positioning notch 22 along with the positioning slider 19, that is, the X-axis positioning block 18 moves on the supporting plate 4;

[0030] In order to fix the position of the workpiece in the X-axis direction on the supporting plate 4, the positioning assembly 7 further includes a Y-axis positioning block 23. The Y-axis positioning block 23 is located between the two positioning sliders 19. The length direction of the Y-axis positioning block 23 is perpendicular to the length direction of the X-axis positioning block 18. To avoid the mutual interference of the X-axis positioning block 18 and the Y-axis positioning block 23 during their movement on the supporting plate 4, a square notch 24 is provided at one end of the Y-axis positioning block 23. The square notch 24 is located on the side of the Y-axis positioning block 23 and horizontally penetrates the Y-axis positioning block 23. The X-axis positioning block 18 passes through the square notch 24, that is, the Y-axis positioning block 23 is sleeved on the X-axis positioning block 18 through the square notch 24. At this time, the Y-axis positioning block 23 and the X-axis positioning block 18 form a vertically crossed connection form. The Y-axis positioning block 23 can move along the length direction of the X-axis positioning block 18, and the Y-axis positioning block 23 moves between the two positioning sliders 19. When the X-axis positioning block 18 moves along the length direction of the positioning chute 20, the Y-axis positioning block 23 moves on the supporting plate 4 along with the X-axis positioning block 18. When the X-axis positioning block 18 and the Y-axis positioning block 23 contact the workpiece, a nut is screwed on the locking rod 21. The nut is located below the supporting plate 4. When the nut is tightened on the locking rod 21, the X-axis positioning block 18 moves downward. At this time, the Y-axis positioning block 23 sleeved on the X-axis positioning block 18 is clamped, that is, the X-axis positioning block 18 and the Y-axis positioning block 23 are fixed on the supporting plate 4. Then, the locking nut is screwed on the threaded rod 9, and the position of the workpiece on the supporting plate 4 is fixed. After the workpiece is drilled, only need to turn the locking nut on the threaded rod 9 so that the cover plate 8 does not contact the workpiece, take out the drilled workpiece, place the workpiece to be drilled on the supporting plate 4 and contact it with the X-axis positioning block 18 and the Y-axis positioning block 23, then make the cover plate 8 contact the workpiece, and screw the locking nut on the threaded rod 9 again. The workpiece is clamped between the supporting plate 4 and the cover plate 8. By analogy, the same batch of workpieces can be drilled conveniently.

[0031] In addition, a cooling mechanism is provided on the drill 3 frame 2. The cooling mechanism includes a coolant spray head 25. The coolant spray head 25 is fixedly installed on the drill 3 frame 2. A water inlet pipe 26 is connected to the coolant spray head 25. The coolant leads from the water inlet pipe 26 to the coolant spray head 25, which can cool the drill 3 and the workpiece during drilling.

[0032] During implementation, place the pre-scored workpiece on the support plate 4, and sleeve the positioning hole 11 onto the threaded rod 9, that is, place the cover plate 8 on the support plate 4. At this time, the workpiece is located between the support plate 4 and the cover plate 8. Rotate the cross bar 15 on the cover plate 8 so that the bottom end of the positioning screw rod 17 contacts the intersection point of the scored line on the workpiece, then the workpiece is positioned. Then move the X-axis positioning block 18 and the Y-axis positioning block 23 on the support plate 4 so that the X-axis positioning block 18 and the Y-axis positioning block 23 respectively contact the ends of the workpiece. Screw the nut onto the locking rod 21, and then screw the locking nut onto the threaded rod 9, and the positioning and fixing of the workpiece can be completed. At this time, rotate the drill bit 3, the cooling water enters the coolant spray head 25 from the water inlet pipe 26, the drill bit 3 moves to contact the workpiece, and drills a hole in the workpiece. The cooling water cools and cleans the workpiece to be drilled and the workpiece and the drill bit 3 during drilling, thus completing the drilling of the workpiece. After drilling is completed, the drill bit 3 returns to the initial position, screw the nut on the threaded rod 9 so that the cover plate 8 does not fix the workpiece, take the drilled workpiece off the support plate 4, take a workpiece of the same batch and place it on the support plate 4, make the end faces of the workpiece respectively contact the X-axis positioning block 18 and the Y-axis positioning block 23, screw the locking nut on the threaded rod 9, and clamp the workpiece between the cover plate 8 and the support plate 4, and the positioning and fixing of the workpiece can be completed. By analogy, the workpieces of the same batch can be drilled conveniently, reducing the workload of the staff.
