[0028] like Figure 1 As shown, a CNC drilling center according to one embodiment of the present invention includes a base 1, a mold 2, a movable frame 3, and several drilling machines 4. The mold 2 extends horizontally and is fixedly mounted on the base 1. A slot 21 for inserting a rod-shaped workpiece to be processed is provided on the top of the mold 2. Both ends of the slot 21 are connected to the outside of the mold 2. One end of the slot 21 is a feed inlet 22. An abutment plate 11 is fixedly installed on the base 1 at the other end of the slot 21. The movable frame 3 is located directly above the base 1 and can move towards or away from the base 1. Mounted on base 1, base 1 is equipped with a first drive member 12 for driving the moving frame 3 to move; several drills 4 are installed at intervals on the moving frame 3 in the direction of extending towards the slot 21, with the drill bits of the drills 4 facing vertically downward and located directly above the slot 21; thus, when the rod-shaped workpiece to be processed is inserted from one end of the feed port 22 until it abuts against the abutment plate 11, and then each drill 4 is driven to move in the direction of the slot 21 simultaneously, the processing of multiple holes in the rod-shaped workpiece to be processed can be completed simultaneously, which greatly improves the processing efficiency of the CNC drilling center.

[0029] like Figure 1 and Figure 2As shown, mounting brackets 13 are fixedly installed at both ends of the base 1 and the movable frame 3. Guide columns 14 are fixedly installed on the mounting brackets 13 and extend vertically. Sliding seats 31 are fixedly installed at the positions of the movable frame 3 corresponding to the mounting brackets 13. The guide columns 14 pass through the sliding seats 31 and the sliding seats 31 are slidably installed on the guide columns 14, so that the movable frame 3 can move stably. The first driving component 12 is a first hydraulic cylinder. A connecting seat 32 is fixedly installed in the middle position between the two sliding seats 31 of the movable frame 3. The first hydraulic cylinder is fixedly installed on the base 1 and the piston rod of the first hydraulic cylinder is fixed on the connecting seat 32, so that the movable frame 3 can be driven to move stably.

[0030] like Figure 1 and Figure 3 As shown, a pressure plate 5 is provided directly above the mold 2 and at the position corresponding to the slot 21. The pressure plate 5 extends along the length direction of the slot 21 and moves toward or away from the mold 2. The base 1 is equipped with a second driving component 15 for driving the pressure plate 5 to move. The second driving component 15 is a second hydraulic cylinder, which is fixedly installed on the base 1. The piston rod of the second hydraulic cylinder is connected to the pressure plate 5. The pressure plate 5 is provided with a clearance hole 51 corresponding to the position of the drill bit of each drill 4. Before drilling, the pressure plate 5 is pressed down to stabilize the rod-shaped workpiece to be processed in the slot 21, thereby improving the accuracy of subsequent drilling.

[0031] The movable frame 3 is fixedly installed with a sliding rail 33 on the side facing the drilling machine 4. The sliding rail 33 extends in the direction of the arrangement of several drilling machines 4. Each drilling machine 4 is fixedly installed with a sliding frame 41, which is slidably installed on the sliding rail 33. The movable frame 3 is equipped with limiting parts to restrict the sliding position of each sliding frame 41. The clearance holes 51 are all elongated holes that extend in the sliding direction of the sliding frame 41. Thus, the position between each drilling machine 4 can be finely adjusted according to the hole positions of different rod-shaped workpieces to be processed, thereby improving applicability.

[0032] The limiting component includes a fixed frame 34 and several limiting screws 35. The fixed frame 34 extends along the length of the sliding track 33 and is fixedly installed on the movable frame 3 and located directly above each sliding frame 41. Several limiting screws 35 are respectively threaded onto the fixed frame 34 at the positions corresponding to each sliding frame 41. The limiting screws 35 pass through the fixed frame 34 and abut against the sliding frame 41. The adjustment position of each drilling rig 4 is limited by the friction between the limiting screws 35 and the sliding frame 41.

[0033] like Figure 1 and Figure 4As shown, a cutting blade 6 is provided at the position of the mold 2 corresponding to the feed port 22. The cutting blade 6 moves horizontally in the direction of extension perpendicular to the slot 21. A third driving component 16 for driving the cutting blade 6 is installed on the base 1. The third driving component 16 is a cylinder, which is fixedly installed on the base 1. The piston rod of the cylinder is fixedly connected to the cutting blade 6. Thus, after drilling is completed, the third driving component 16 can be activated to cut the long strip of raw material, which increases the function of the CNC drilling center and improves its practicality.

[0034] like Figure 1 As shown, handles 17 are fixedly installed at both ends of the base 1 to facilitate the transfer of the CNC drilling center.

[0035] The implementation principle of a CNC drilling center according to an embodiment of this application is as follows: During processing, the rod-shaped workpiece to be processed is first inserted into the slot 21 from the feed port 22. Then, the second drive component 15 is activated to drive the pressure plate 5 to press down and stabilize the rod-shaped workpiece to be processed in the slot 21. Then, the first drive component 12 is activated to drive the moving frame 3 to move towards the base 1, thereby driving each drilling machine 4 to move synchronously towards the mold 2 until drilling is performed on each hole of the rod-shaped workpiece to be processed.
