The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] A punching machine, such as Figure 1-5As shown, it includes a mounting platform 1, a mounting plate 15 is fixed to the top outer wall of the mounting platform 1, a group of guide rails 11 are fixed to the outer wall of one side of the mounting plate 15, a movable plate 13 is slidably connected to the outer wall of the guide rail 11, a connecting block 16 is fixed to the outer wall of the movable plate 13, a drilling machine 14 is fixed to the inner wall of the connecting block 16, and the output shaft of the drilling machine 14 is connected to the drill bit 2;

[0030] A set of electric lead screw guide rails 22 are fixed to the outer wall of one side of the mounting plate 15, and a slider 23 is connected to the outer wall of the electric lead screw guide rail 22 through a lead screw. An L-shaped connecting plate 12 is fixed to the top outer wall of the slider 23, and the bottom outer wall of the L-shaped connecting plate 12 is fixed to the top outer wall of the connecting block 16;

[0031] The inner wall of the mounting plate 15 is fixed with a pneumatic clamp 19, the output ends of the pneumatic clamp 19 are respectively connected with clamp rods 27, the inner wall of the clamp rod 27 is fixed with a chuck 28, and the outer wall of one side of the clamp rod 27 is provided with a drill rod guide 26, and the drill rod guide 26 penetrates the outer wall of one side of the chuck 28;

[0032] The inner wall of the mounting plate 15 is fixed with a cylinder 24, the output shaft of the cylinder 24 is fixed with a support plate 25, the outer wall of the pneumatic clamp 19 is fixed with an adjustment bracket 9, the outer wall of the adjustment bracket 9 is connected with an adapter 6, the outer wall of the bottom of the adapter 6 is plugged with a feed pipe 10, the outer walls of both sides of the feed pipe 10 are respectively provided with reserved holes 29, and the support plate 25 is slidably connected to the bottom outer wall of the feed pipe 10;

[0033] The outer wall of the mounting platform 1 is fixed with an air source processor 18 and a pneumatic solenoid valve 20. The air source processor 18 is connected to the input end of the pneumatic solenoid valve 20 through an air pipeline. The pneumatic solenoid valve 20 is connected to the pneumatic gripper 19 and the cylinder 24 through an air pipeline.

[0034] A numerical control PLC panel 7 is fixed to the outer wall of the installation platform 1, and the pneumatic solenoid valve 20, the electric lead screw slide 22 and the drilling machine 14 are electrically connected to the numerical control PLC panel 7 respectively;

[0035] A lower hopper 8 is inserted into the outer wall of the top of the adapter 6;

[0036] The staff first pours the balls to be drilled into the feeding tube 10 through the feeding hopper 8. At this time, the support plate 25 at the bottom of the feeding tube 10 will cover the bottom opening of the feeding tube 10 to prevent the balls from rolling out from the bottom of the feeding tube 10. Then the CNC PLC panel 7 controls the operation of the drilling rig 14 and the electric lead screw guide rail 22. When the electric lead screw guide rail 22 drives the movable plate 13 to move forward as a whole, the pneumatic solenoid valve 20 supplies air to the pneumatic clamp 19, so that the clamp rod 27 drives the clamp 28 on one side to move forward, and passes through the reserved hole 29 to clamp the balls inside the feeding tube 10. Then the drilling rig 14 and the electric lead screw guide rail 22 are controlled to operate. The drill rod installed on one side of the head 2 passes through the drill rod guide 26 and enters the interior of the feeding tube 10 to drill the clamped round balls. At the same time, the pneumatic solenoid valve 20 stops supplying air to the cylinder 24, so that the output shaft of the cylinder 24 drives the support plate 25 to be recovered, and the support plate 25 is released from blocking the bottom of the feeding tube 10, so that the round balls that have been drilled by the drill rod roll down from the feeding tube 10. Since the round balls at the top of the round balls are being clamped by the chuck 28 at this time, during the period when the support plate 25 leaves the bottom of the feeding tube 10, only the round balls that have been drilled and are located at the bottom of the support plate 25 will roll out from the bottom of the feeding tube 10.

[0037] When the drilling is completed, the electric lead screw slide 22 drives the movable plate 13 to move back and reset, the CNC PLC panel 7 will control the pneumatic solenoid valve 20 to supply air to the cylinder 24 again, so that the cylinder 24 pushes the support plate 25 forward again, and the bottom of the feeding pipe 10 is re-blocked. At the same time, the pneumatic solenoid valve 20 stops supplying air to the pneumatic clamp 19, and releases the clamping of the chuck 28 on the ball after the drilling on one side, so that the ball after drilling can roll to the top of the support plate 25, and the ball waiting for drilling can continue to fall to the side of the reserved hole 29, and then repeat the above steps to continuously drill the ball.

[0038] like Figure 1 As shown, a guide plate 3 is fixed to the outer wall of one side of the mounting plate 15; the guide plate 3 can guide the balls dropped from the bottom of the feed pipe 10, so that the staff can collect the balls after drilling.

[0039] like Figure 3-4 As shown, the outer wall of the pneumatic clamping jaw 19 is sleeved with an elastic rubber sleeve 17, and the clamping rod 27 penetrates the outer wall of one side of the elastic rubber sleeve 17; the elastic rubber sleeve 17 can shield and seal the connection between the pneumatic clamping jaw 19 and the clamping rod 27.

[0040] like Figure 2As shown, a group of proximity switches 21 are arranged on the outer wall of one side of the mounting plate 15, and the proximity switches 21 are electrically connected to the CNC PLC panel 7; the proximity switches 21 can sense the position of the slider 23 moving forward and backward, so that the CNC PLC panel 7 can accurately control the pneumatic clamp 19 and the cylinder 24 to operate appropriately through the pneumatic solenoid valve 20 according to the sensing signal of the proximity switch 21, thereby improving the stability of the punching machine during operation.

[0041] like Figure 1 As shown, a connecting piece 5 is fixed to the outer wall of one side of the adapter 6, and a dust suction pipe 4 is fixed to the outer wall of the connecting piece 5; the staff connects the dust suction pipe 4 to an external dust suction device, so that the dust suction pipe 4 absorbs the debris generated during the drilling process.

[0042] Working principle: The staff first pours the balls to be drilled into the feed tube 10 through the feed hopper 8. At this time, the support plate 25 at the bottom of the feed tube 10 will cover the bottom opening of the feed tube 10. Then the CNC PLC panel 7 controls the operation of the drilling machine 14 and the electric lead screw guide rail 22. When the electric lead screw guide rail 22 drives the movable plate 13 to move forward as a whole, the pneumatic solenoid valve 20 supplies air to the pneumatic clamp 19, so that the clamp rod 27 drives the clamp on one side. 28 moves forward, passes through the reserved hole 29 to clamp the ball inside the feeding tube 10, and then the drill rod installed on one side of the drill bit 2 passes through the drill rod guide 26 to enter the feeding tube 10 to drill the clamped ball. At the same time, the pneumatic solenoid valve 20 stops supplying air to the cylinder 24, so that the output shaft of the cylinder 24 drives the support plate 25 to retract, and the support plate 25 is released from covering the bottom of the feeding tube 10, so that the ball that has been drilled by the drill rod rolls out of the feeding tube 10;

[0043] When the drilling is completed, the electric lead screw slide 22 drives the movable plate 13 to move back and reset, the CNC PLC panel 7 will control the pneumatic solenoid valve 20 to supply air to the cylinder 24 again, so that the cylinder 24 pushes the support plate 25 forward again, and the bottom of the feeding pipe 10 is re-blocked. At the same time, the pneumatic solenoid valve 20 stops supplying air to the pneumatic clamp 19, and releases the clamping of the chuck 28 on the ball after the drilling on one side, so that the ball after drilling can roll to the top of the support plate 25, and the ball waiting for drilling can continue to fall to the side of the reserved hole 29, and then repeat the above steps to continuously drill the ball.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
