[0027] Reference Figure 1-Figure 4 The utility model provides a technical solution: a drilling and tapping device, comprising a main box 1, a top plate 2 is fixedly installed on the top surface of the main box 1, a placement plate 3 is fixedly installed in the middle of the top surface of the top plate 2, a fixing frame 4 is fixedly connected to the top surface of the top plate 2, a cylinder 5 is fixedly installed on the top surface of the fixing frame 4, an output end of the cylinder 5 is fixedly connected to a mounting plate 6, and a servo drilling machine 7 and a servo tapping machine 8 are fixedly installed inside the mounting plate 6;

[0028] Specifically, the cleaning assembly includes two boxes 11, which are fixedly mounted on the two ends of the top surface of the fixing frame 4, and are symmetrically arranged. An air bag 13 is fixedly mounted inside the box 11, and a clamping plate 14 is movably clamped inside the box 11. The top surface of the clamping plate 14 is bonded to the bottom surface of the air bag 13, and the bottom surface of the clamping plate 14 is fixedly connected to a connecting rod 10. One end of the connecting rod 10 penetrates the fixing frame 4 and extends to the bottom of the fixing frame 4. The other end of the connecting rod 10 is fixedly connected to an extension plate 9. One side surface of the extension plate 9 is fixedly connected to one side surface of the mounting plate 6. An air inlet pipe 16 is fixedly connected to the top surface of the box 11. A one-way valve 17 is fixedly mounted on the outer surface of the air inlet pipe 16. One end of the air inlet pipe 16 extends to the interior of the air bag 13. An air outlet pipe 12 is fixedly connected to one side surface of the box 11. A one-way valve 15 is fixedly installed on the outer surface of the air outlet pipe 12, and a diverter frame 18 is provided at both ends of the top surface of the top plate 2. A plurality of jet pipes 19 are fixedly connected to one side surface of the diverter frame 18, and a nozzle 20 is fixedly installed at one end of each of the plurality of jet pipes 19. When the cylinder 5 drives the servo tapping machine 8 to move downward, the clamping plate 14 inside the box body 11 is driven to move downward inside the box body 11 through the extension plate 9 and the connecting rod 10, and the air enters the inside of the airbag 13 through the air inlet pipe 16. When the cylinder 5 drives the servo drilling machine 7 to move upward, the airbag 13 is squeezed, and the air inside the airbag 13 is squeezed into the inside of the air outlet pipe 12, and is blown toward the top of the placement plate 3 through the jet pipe 19 and the nozzle 20, so that the debris scattered on the top surface of the placement plate 3 during drilling is blown away from the top surface of the placement plate 3;

[0029] Specifically, the adjustment component includes a threaded sleeve 23, and there are two threaded sleeves 23. The two threaded sleeves 23 are respectively fixedly installed inside the two sides of the fixing frame 4. The internal thread of the threaded sleeve 23 is connected with a threaded rod 24, and a knob 25 is fixedly installed at one end of the threaded rod 24. The other end of the threaded rod 24 is rotatably installed on the surface of one side of the diverter frame 18. By holding the knob 25 and rotating it clockwise and counterclockwise, the threaded rod 24 rotates inside the threaded sleeve 23. Under the action of the thread, the diverter frame 18 can be driven to move back and forth on the top surface of the main box 1, which is used to adjust the distance between the diverter frame 18 and the placement plate 3. The distance between the diverter frame 18 and the placement plate 3 controls the size of the wind blown toward the placement plate 3, thereby realizing the control of the blown wind force, which is suitable for cleaning debris of different materials.

[0030] Specifically, both ends of the top surface of the top plate 2 are provided with a snap-in groove 21, and a movable block 22 is movably snap-into the inside of the snap-in groove 21. The top surface of the movable block 22 is fixedly connected to the bottom surface of the diverter rack 18. By setting the snap-in groove 21 and the movable block 22, the movable block 22 moves synchronously with the adjustment movement of the diverter rack 18, thereby ensuring the stability of the diverter rack 18 during the movement.

[0031] Specifically, the outer surface of the knob 25 is provided with a plurality of anti-skid grooves, and the plurality of anti-skid grooves are equidistantly provided on the outer surface of the knob 25. By providing the plurality of anti-skid grooves, the friction between the palm and the knob 25 can be increased during the process of holding the knob 25 and rotating it, thereby preventing the palm and the knob 25 from slipping and facilitating the rotation of the threaded rod 24.

[0032] Specifically, the working process or working principle of this drilling and tapping device is: when in use, the parts that need to be drilled and tapped are first placed on the top surface of the placement plate 3, and first located below the servo drilling machine 7, and then the servo drilling machine 7 is driven downward by the control cylinder 5 to drill the parts. After the drilling is completed, the drilled parts are fixed to the bottom of the servo tapping machine 8, and the servo tapping machine 8 is also driven downward by the cylinder 5 to tap the parts.

[0033] Among them, when the cylinder 5 drives the servo tapping machine 8 to move downward, the clamping plate 14 inside the box 11 can be driven to move downward inside the box 11 through the extension plate 9 and the connecting rod 10. During the movement, the airbag 13 can be pulled, and the air gradually enters the inside of the airbag 13 through the air inlet pipe 16, and the airbag 13 is in an expanded state. When the drilling is completed, the cylinder 5 drives the servo drilling machine 7 to move upward, driving the clamping plate 14 to move upward inside the box 11, squeezing the airbag 13, squeezing the air inside the airbag 13 into the inside of the air outlet pipe 12, and entering the inside of the diverter rack 18, and finally blowing it toward the top of the placement plate 3 through the jet pipe 19 and the nozzle 20, blowing the debris scattered on the top surface of the placement plate 3 during drilling away from the top surface of the placement plate 3, and after the tapping operation, the same principle is used, thereby achieving the purpose of automatically cleaning the debris on the top surface of the placement plate 3 during drilling and tapping.

[0034] Furthermore, before the drilling and tapping operations, the knob 25 can be held and rotated clockwise or counterclockwise to allow the threaded rod 24 to rotate inside the threaded sleeve 23. The thread can drive the diverter rack 18 to move back and forth on the top surface of the main chassis 1 to adjust the distance between the diverter rack 18 and the placement plate 3. The size of the wind force blown toward the placement plate 3 can be controlled by the distance between the diverter rack 18 and the placement plate 3, thereby achieving control of the blown wind force for cleaning debris of different materials. For example, for iron filings, the diverter rack 18 can be closer to the placement plate 3, and for wood chips, the diverter rack 18 can be adjusted farther away to prevent the wind from being too strong and blowing the debris into the air.

[0035] It should be noted that the cylinder 5, the servo drilling machine 7 and the servo tapping machine 8 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
