[0010] Preferably, two guide rods are installed through the upper end of the bearing seat, and the guide rods are slidably matched with the bearing seat, and a pressure cap is fixedly installed on the upper end of the guide rod, and a fixing frame is fixedly installed on the upper end of the pressure cap, and the end of the fixing frame is fixed to the lifting seat, and a limiting cap is coaxially inlaid on the lower end of the guide rod, and the upper end of the limiting cap is attached to the lower end of the bearing seat, and a No. 1 compression spring is wound around the outer side of the two guide rods, and the upper end of the No. 1 compression spring is fixed to the lower end of the pressure cap, and the lower end of the No. 1 compression spring is fixed to the upper end of the bearing seat.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The downward moving lifting seat can drive the No. 1 driving motor to move downward and approach the upper end of the workpiece. At this time, the top seat is driven by the lifting seat and moves downward synchronously to contact the top wheel. Then the lifting seat continues to move downward, allowing the No. 1 drill bit to contact the workpiece for drilling. At this time, the top seat continues to move downward, allowing the top wheel to roll along the lower end inclined surface of the top seat to push the No. 2 drill bit, so that the No. 2 drill bit can contact the workpiece for drilling. In this way, the workpiece can be drilled in both directions at the same time, which effectively shortens the drilling time and improves the drilling efficiency.

[0013] 2. When the No. 1 drill bit and the No. 2 drill bit are about to collide, the top wheel is just in the vertical section in the middle of the top seat, and then the lifting seat continues to move down. At this time, the top wheel rolls in the middle of the top seat, so that the No. 2 drill bit will not continue to advance. At the same time, the No. 1 drill bit continues to move down to turn the circular hole depth on the top of the workpiece to a position flush with the hole on the side of the workpiece. At this time, the pressure column just contacts the top column, and then the lifting seat continues to move down to drive the No. 1 tooth plate to move down. At this time, the gear remains stationary under the support of the top column, so that the downward-moving No. 1 tooth plate can drive the stationary gear to rotate, thereby driving the No. 2 tooth plate to move up, and then driving the No. 1 drill bit to move up. At this time, the top wheel is at the upper part of the top seat, and then the top seat is driven by the lifting seat to continue to move down, so that the top wheel can roll on the upper inclined surface of the top seat, allowing the No. 2 drill bit to continue to advance and drill, so as to open the two holes in both directions and make them connected. The process avoids the collision between the No. 1 drill bit and the No. 2 drill bit.

[0014] 3. When the top column supports the pressure column, the lifting seat continues to move downward to drive the No. 2 tooth plate to move upward, and then drives the No. 1 drill bit to move upward. The No. 2 compression spring and the No. 1 compression spring will be deformed to avoid the lifting seat from being hindered by the No. 2 tooth plate and the gear when it continues to move downward, thereby ensuring the normal downward movement of the lifting seat.

[0026] When the present invention is in use, the clamping mechanism 42 is used to clamp and fix the workpiece, and then the servo motor 3 works to drive the threaded rod 11 to rotate, so that the lifting seat 4 screwed on the threaded rod 11 moves downward. At this time, the slide seat 12 slides on the guide rod 13 to assist the lifting seat 4 to move downward, so that the No. 1 driving motor 5 is driven by the downwardly moved lifting seat 4 to move downward and approach the upper end of the workpiece. At this time, the top seat 7 is driven by the lifting seat 4 and moves downward synchronously to contact the top wheel 40. Then the lifting seat 4 continues to move downward, so that the No. 1 drill bit 6 on the No. 1 driving motor 5 contacts the workpiece for drilling. At this time, the top seat 7 continues to move downward, so that the top wheel 40 can roll along the lower end inclined surface of the top seat 7 to push the No. 2 drill bit 34 so that the No. 2 drill bit 34 can contact the workpiece for drilling. When the No. 1 drill bit 6 and the No. 2 drill bit 34 are about to collide, the top wheel 40 is just in the vertical section in the middle of the top seat 7. After that, the lifting seat 4 continues to move downward. At this time, the top wheel 40 rolls in the middle of the top seat 7, so that the No. 2 drill bit 34 will not continue to advance. At the same time, the No. 1 drill bit 6 continues to move downward to turn the circular hole on the top of the workpiece to a position flush with the hole on the side of the workpiece. At this time, the pressure column 29 just contacts the top column 16, and then the lifting seat 4 continues to move downward to drive the No. 1 gear plate 23 to move downward. At this time, the gear 30 remains stationary under the support of the top column 16, so that the No. 1 gear plate 23 that moves downward drives the stationary gear 30 to rotate, thereby driving the No. 2 gear plate 41 to move upward, and then driving the No. 1 drill bit 6 to move upward. At this time, the top wheel 40 is at the upper part of the top seat 7, and then the top seat 7 is driven by the lifting seat 4 to continue to move downward, so that the top wheel 40 can roll on the upper inclined surface of the top seat 7, allowing the No. 2 drill bit 34 to continue to advance and punch, so as to open the two holes in both directions, that is, to open two connected holes on the workpiece, thereby completing the punching operation.
