Leveling feet 103 are provided at the bottom of the front frame 101 and the rear frame 102 .

[0020] The rod support frame is used to support and guide the processing materials to be processed. The roller 2302 can reduce the friction resistance between the processing materials and the rod support frame 23, so that the processing materials can smoothly enter the drilling mechanism 10, and at the same time keep the processing materials stable during the processing. The function of the fixed cylinder 2301 is to cooperate with the clamping rod feeding mechanism 2 to enable the processing materials to be accurately positioned to the drilling mechanism 10 to prevent the processing materials from being offset. The leveling foot 103 is used to adjust the horizontality of the base frame 1 to ensure that the equipment remains horizontal and stable during use. Even if the ground flatness of the use site is not good enough, the influence of adverse site factors can be overcome by adjusting the leveling foot 103 to improve the adaptability of the equipment. The main function of the feed module 3 is to position the processing materials to the drilling mechanism 10 according to the production parameter requirements. The upper drilling module 17 and the lower drilling module 18 are installed in a relative form of drill bits to achieve simultaneous drilling of the processing materials from top to bottom.

[0021] The feed module 3 is connected to the front frame 101 through a guide rail slider, and the guide rail slider is connected to an adjusting screw 4. There are four adjusting screws 4, which penetrate a feed base plate 5. The feed base plate 5 is provided with a clamping cylinder 6, an end detection element 7, a rod detection sensor element 8, and a support wheel group 9.

[0022] The support wheel group 9 is located on the side of the feed base plate 5 close to the rod support frame 23, the rod clamping cylinder 6 and the end detection element 7 are located on the side of the feed base plate 5 close to the rear frame 102, the number of the end detection elements 7 is two, which are respectively arranged on both sides of the rod clamping cylinder 6, and the number of the rod detection sensor elements 8 is two, which are respectively arranged on both sides of the support wheel group 9.

[0023] The supporting wheel group 9 can support the processing material extending from the rod supporting frame 23. The end detection element 7 is used to detect the end position of the material, and the rod detection sensor element 8 is used to detect whether the processing material has entered the range of the feeding module 3.

[0024] The drilling mechanism 10 is fixed on the rear frame 102 through a module mounting frame 11. The module mounting frame 11 is provided with two vertical guide rails 16. The upper drilling module 17 and the lower drilling module 18 are respectively mounted on the upper and lower ends of the guide rails 16 by slide blocks. A drilling pad 19 is provided between the upper drilling module 17 and the lower drilling module 18, and the drilling pad 19 is fixedly connected to the module mounting frame 11.

[0025] A first motor 12 and a second motor 13 are disposed on the top of the module mounting frame 11 . The first motor 12 is connected to the upper drilling module 17 via a first ball screw 14 , and the second motor 13 is connected to the lower drilling module 18 via a second ball screw 15 .

[0026] Two adjusting screws 20 are arranged on the drilling pad 19 . The adjusting screws 20 are fixedly connected with a centering cylinder 21 . The centering cylinder 21 is provided with a centering roller set 22 .

[0027] The top of the module mounting frame 11 is provided with a first motor 12 and a second motor 13. In this embodiment, the first motor 12 and the second motor 13 use servo motors to achieve efficient and accurate positioning and improve the drilling process. The first motor 12 is connected to the upper drilling module 17 through the first ball screw 14, and the second motor 13 is connected to the lower drilling module 18 through the second ball screw 15, so that the upper drilling module 17 and the lower drilling module 18 can be accurately positioned and moved in the vertical direction. The function of the centering roller group 22 is to ensure the horizontality and stability of the processed material, thereby ensuring the accuracy and consistency of the drilling.

[0028] The specific working method of the automatic punching machine is as follows: place the processing material to be drilled on the roller 2302 of the rod support frame 23. Taking the processing of metal rod material as an example, push the rod head into the detection range of the rod detection sensor element 8. When the rod detection sensor element 8 detects the metal rod, the fixed cylinder 2301 on the rod support frame 23 is controlled by an electrical signal to clamp the metal rod, and at the same time start the feeding module 3. Through the cooperation of the motor, guide rail and slider of the feeding module 3, the feeding base plate 5 is moved toward the direction of the rod support frame 23 until the end detection element 7 detects the rod head. Since the fixed cylinder 2301 fixes the metal rod and a supporting wheel group 9 is provided on the feeding base plate 5, the metal rod remains relatively stationary during the movement of the feeding module 3.

[0029] When the end detection element 7 detects the metal rod, the feed module 3 will continue to move a certain distance in the original direction according to the preset parameters until the clamping cylinder 6 can clamp the metal rod, and then control the fixed cylinder 2301 through an electrical signal to release the metal rod, so that the feed module 3 can push the metal rod into the drilling mechanism 10.

[0030] According to the preset processing requirements, the feed module 3 drives the metal rod to move toward the drilling mechanism 10, and when the metal rod enters the drilling mechanism 10, the drill bits of the upper drilling module 17 and the lower drilling module 18 are aligned with the preset drilling positions. After the metal rod is in place, the centering cylinder 21 clamps the metal rod, and the centering wheel group 22 keeps the center of the metal rod and the center of the drill bits installed on the upper drilling module 17 and the lower drilling module 18 in a straight line.

[0031] The first motor 12 and the second motor 13 are started, driving the upper drilling module 17 and the lower drilling module 18 to move vertically along the guide rail 16 to drill holes on the upper and lower surfaces of the metal rod simultaneously.

[0032] After the drilling process is completed, the first motor 12 and the second motor 13 respectively drive the upper drilling module 17 and the lower drilling module 18 to retreat. At the same time, the centering cylinder 21 releases the metal rod, and the feed module 3 moves the metal rod backward toward the rod support frame 23. After retreating into place, the clamping cylinder 6 releases the metal rod, and the entire drilling process is completed.

[0033] This embodiment: realizes simultaneous upper and lower processing without turning over the processing material, can maintain better concentricity of drilling, and improves efficiency at the same time; realizes automatic feeding without manual control, has higher drilling position accuracy, and has high stability of processing quality; can also dig long holes according to process requirements; the servo motor drives the drilling module to feed, and the feeding is more stable, which effectively prevents product edge collapse.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
