The design of the double electric drill bits 13 is suitable for workpieces that need symmetrical punching, so that the two electric drill bits 13 can work synchronously, thereby increasing the work efficiency. The inner cavities of the convex grooves on both sides of the slot plate 2 are slidably connected with sliders 3, and the tops of the two sliders 3 are fixedly provided with limit plates 4, and the internal threads of the sliders 3 are connected with bolts 5, and the threaded ends of the bolts 5 are tightly pressed against the bottom of the inner cavity of the convex groove. Through the sliding connection between the slider 3 and the slot plate 2, the positions of the two limit plates 4 can be adjusted, so that workpieces of different sizes can be positioned, and a baffle plate 6 is arranged above the slot plate 2. 6 is parallel to the rear end surface of the casing 1, so that the vertical position of the workpiece can be positioned. The inner cavity of the casing 1 is fixedly provided with two parallel sliding rods 8 along the length direction. Sliding sleeves 9 are sleeved on both sides of the outer wall of the sliding rod 8. A slide plate 10 is fixedly provided between the two corresponding slide sleeves 9. The movement of the two slide plates 10 can be limited by the cooperation between the slide sleeves 9 and the sliding rod 8. A driving component is provided between the two slide plates 10. The position of the slide plate 10 can be controlled by the operation of the driving component. A second cylinder 11 is installed inside the slide plate 10. The movable end of the second cylinder 11 is fixedly connected to the electric drill bit 13 through the mounting plate 12. After the position of the slide plate 10 is determined, the electric drill bit 13 can be driven downward by the second cylinder 11, and the workpiece can be punched under the operation of the electric drill bit 13.

[0015] Specifically, the driving assembly includes a motor 14, which is installed on the top of the casing 1. The output end of the motor 14 is movable through the top of the casing 1. A gear 15 is fixedly provided at the output end of the motor 14. The motor 14 can drive the gear 15 to rotate. Racks 16 are meshed on both sides of the outer wall of the gear 15. The two racks 16 are respectively fixed on the inner sides of the two slides 10. The meshing of the gear 15 and the rack 16 can drive the two slides 10 to move toward each other, thereby controlling the distance between the two electric drill bits 13.

[0016] Specifically, a first cylinder 7 is fixedly installed on the rear end face of the casing 1, and a movable end of the first cylinder 7 is fixedly connected to the baffle 6. The operation of the first cylinder 7 can drive the baffle 6 to adjust its position, and further the vertical position can be positioned according to workpieces of different specifications.

[0017] Specifically, two groove wheels 17 are rotatably provided at the top of the inner cavity of the casing 1, and the two groove wheels 17 are movably connected to the outer sides of the two racks 16 respectively. Through the design of the groove wheels 17, the racks 16 can be limited to make the connection between the racks 16 and the gears 15 more stable.

[0018] According to the personnel in this field, all the electrical parts and components in this case are universal standard parts or components known to the technical personnel in this field, and their structures and principles can be known to the technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All the electrical parts in this case are connected to the power supply adapted to them through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0019] Working principle: When the punching device is used, the baffle plate 6 is driven by the first cylinder 7 to adjust its front and rear position, so that the vertical position of the workpiece (generally a plate-shaped workpiece) is determined, and finally the two bolts 5 are loosened so that the two slide blocks 3 can drive the limit plate 4 to move. When the limit plate 4 is attached to the side of the workpiece, the bolts 5 are tightened to fix the position of the slide block 3. At this time, the position of the workpiece is determined (the workpiece can be supported by hand according to actual conditions), and then the motor 14 is started. Under the operation of the motor 14, the gear 15 can be driven to rotate, and the rotating gear 15 can be driven by the motor 14. The engagement with the two racks 16 drives the two slides 10 to move toward each other, and then the movement of the two electric drill bits 13 can adjust the symmetrical spacing of the punching holes in the workpiece. After the adjustment is completed, the second cylinder 11 and the electric drill bit 13 can be started. The operation of the second cylinder 11 can drive the electric drill bit 13 to impact the punching position of the workpiece, so that two symmetrical holes of the workpiece can be processed at the same time. After the processing is completed, the workpiece can be directly removed for processing the next workpiece, which can be used for mass production of workpieces, thereby making the punching device more applicable.
