[0025] Reference Figure 1 A smart drilling and tapping machine with visual recognition function includes a machine base 1, a drilling and tapping mechanism 2, and a positioning mechanism 3. The positioning mechanism 3 is fixedly connected to the machine base 1 and is used to clamp and fix the workpiece 4 to be drilled, ensuring that the workpiece 4 will not move or deform during the drilling process, thereby improving the accuracy and stability of the drilling. A moving mechanism 5 is provided on the machine base 1, and the drilling and tapping mechanism 2 is set above the positioning mechanism 3 through the moving mechanism 5. The moving mechanism 5 can drive the drilling and tapping mechanism 2 to move on the machine base 1, so that the drilling and tapping mechanism 2 can be flexibly positioned at any position of the workpiece 4 to be drilled, improving the adaptability and flexibility of the equipment. The drilling and tapping mechanism 2 includes a drill bit 6 and a visual recognition camera 7. The visual recognition camera 7 is arranged side by side with the drill bit 6. The workpiece 4 is provided with a drilling hole. During the drilling process, the drilling and tapping hole can be visually recognized by the real-time visual recognition camera 7 to ensure the accuracy of the drilling position, thereby avoiding problems such as tool breakage, tap breakage, and screw hole deformation during tapping. The intelligent drilling and tapping machine of this utility model integrates a machine base 1, a drilling and tapping mechanism 2, a positioning mechanism 3, and a moving mechanism 5, forming a complete automated drilling and tapping system. This improves the overall integrity and coordination of the equipment, reduces reliance on external equipment, and enhances work efficiency.

[0026] Reference Figure 2 , Figure 3In an embodiment of this utility model, the drilling and tapping mechanism 2 further includes a sliding plate 21 and a lifting assembly 22. Multiple lifting assemblies 22 are fixed side by side on the sliding plate 21. The drill bit 6 and the visual recognition camera 7 are both fixed on the lifting assembly 22, which realizes the height adjustability of the drill bit 6 and the visual recognition camera 7. The working height of the drill bit 6 and the visual recognition camera 7 can be precisely adjusted according to the thickness and shape of the workpiece 4 to be drilled, thereby improving the flexibility and accuracy of drilling and tapping.

[0027] Specifically, the lifting assembly 22 includes a lifting cylinder 221, a slide rail 222, a slider 223, and a fixed base 224. The slide rail 222 is fixedly connected to the sliding plate 21, the slider 223 is slidably connected to the slide rail 222, and the fixed base 224 is fixedly connected to the slider 223. The lifting cylinder 221 is fixed to the upper end of the slide rail 222, and the extended end of the lifting cylinder 221 is fixedly connected to the fixed base 224. The drill bit 6 and the visual recognition camera 7 are also included. Fixed on the fixed base 224, the lifting cylinder 221 can drive the slider 223 to move up and down along the slide rail 222, thereby causing the fixed base 224 to drive the drill bit 6 and the visual recognition camera 7 to move up and down. The lifting cylinder 221 provides power, the slide rail 222 and the slider 223 ensure the smoothness and accuracy of the lifting process, and the fixed base 224 is used to fix the drill bit 6 and the visual recognition camera 7. This not only improves the accuracy of the lifting of the drill bit 6 and the visual recognition camera 7, but also ensures the stability of the drilling process.

[0028] Specifically, the lower end of the slide rail 222 is also provided with a limit block 225, which plays a safety protection role. When the lifting cylinder 221 extends to the limit position, the limit block 225 can prevent the fixed seat 224 from continuing to descend, thereby avoiding collision between the drill bit 6 or the visual recognition camera 7 and the workpiece 4, and ensuring the safe operation of the equipment.

[0029] Specifically, a horizontal slider 23 is provided on the back of the sliding plate 21. The horizontal slider 23 is slidably connected to the moving mechanism 5, so that the drilling and tapping mechanism 2 can move laterally on the machine base 1, which further enhances the flexibility of the drilling and tapping mechanism 2, enabling it to cover a larger working area and adapt to workpieces 4 of different sizes.

[0030] Reference Figure 1In an embodiment of this utility model, the moving mechanism 5 is configured as a two-dimensional moving system, including an X-axis moving component 51 and a Y-axis moving component 52. The Y-axis moving component 52 is disposed at both ends of the machine base 1. The two ends of the X-axis moving component 51 are slidably connected to the Y-axis moving component. The transverse slider 23 is slidably connected to the X-axis moving component 51, so that the drilling and tapping mechanism 2 can perform precise two-dimensional movement on the machine base 1, further enhancing the flexibility and applicability of the equipment.

[0031] Reference Figure 2 In an embodiment of this utility model, a sheet metal bracket 8 is provided on the outside of the visual recognition camera 7. The sheet metal bracket 8 is connected to the fixing base 224. A ring light source 9 is fixedly connected to the lower end of the sheet metal bracket 8. The visual recognition camera 7 and the ring light source 9 are on the same center line. The sheet metal bracket 8 is not only used to fix the visual recognition camera 7, but also integrated with the ring light source 9 at its lower end, thereby improving the accuracy and stability of visual recognition.

[0032] In addition, the drill bit 6 is connected to a rotary motor 10, which is fixedly connected to the fixed base 224, so that the drill bit 6 can rotate to ensure that the drill bit 6 can perform drilling operations on the workpiece 4 normally, with a high degree of automation.

[0033] Reference Figure 4 In an embodiment of this utility model, the positioning mechanism 3 includes a worktable 31, a guide rail 32, and sliding jaws 33. The guide rail 32 includes an X-axis guide rail 321, two Y-axis guide rails 322, and an X-axis sliding plate 323, forming a multi-dimensional positioning frame. The X-axis guide rail 321 and the two Y-axis guide rails 322 are respectively disposed at the edge of the worktable 31. The X-axis sliding plate 323 is disposed opposite to the X-axis guide rail 321, and both ends of the X-axis sliding plate 323 are slidably connected to the two Y-axis guide rails 322, thereby achieving precise sliding adjustment in the X-axis and Y-axis directions. In addition, two sliding jaws 33 are respectively disposed on the X-axis guide rail 321 and the X-axis sliding plate 323. When positioning the workpiece, the sliding jaws 33 abut against the corner of the workpiece 4 to achieve precise positioning and ensure stability during drilling.

[0034] Specifically, the positioning mechanism 3 further includes multiple X-axis positioning blocks 34 and Y-axis positioning blocks 35. The X-axis positioning blocks 34 and Y-axis positioning blocks 35 serve as auxiliary positioning. The multiple X-axis positioning blocks 34 are spaced apart on the inner end of the X-axis guide rail 321 to further position the workpiece 4 in the X-axis direction. The multiple Y-axis positioning blocks 35 are disposed on the inner end of the Y-axis guide rail 322 to provide additional positioning support in the Y-axis direction, effectively preventing the workpiece 4 from shifting or shaking during the positioning process and enhancing the stability of the positioning.

[0035] Furthermore, the positioning mechanism 3 in this embodiment is designed to position workpieces 4 of different sizes and shapes. By adjusting the position of the sliding jaw 33 and the use of the X-axis and Y-axis positioning blocks, it can adapt to the positioning requirements of various workpieces.
