[0033] Example 1

[0034] See also Figure 1-3 The present invention provides a technical solution: a fastener drilling device, including a platform 1, an electric control cabinet 2, and a feed bracket 3. The interior of the platform 1 is a hollow structure, and a circular blind hole is connected to the front of the platform 1. Two blowers are rotatably connected to the top of the platform 1 to blow away dust falling on the surface of the device from the outside. The blower of the platform 1 is electrically connected to the electric control cabinet 2 through a wire. The feed bracket 3 includes a slide platform 31, the slide platform 31 is fixedly connected to the top of the platform 1, and the electric control cabinet 2 is fixedly connected to the left side of the slide platform 31. A slide frame 32 is slidably connected to the top of the slide platform 31, and a vibration sensor is embedded in the slide frame 32. The slide frame 32 is slidably connected to the top of the platform 1 through a screw rod and a servo motor. A drill assembly 33 is fixedly connected to the bottom of the slide frame 32. The drill assembly 33 includes a drill rod, and the drill assembly 33 is electrically connected to the electric control cabinet 2 through a wire.

[0035] The top of the platform 1 is slidably connected to a magnetic slide 4, which includes a sliding base 41. The sliding base 41 is made of cast iron. Circular blind holes are provided on the front, back, left and right sides of the sliding base 41. The front and back of the sliding base 41 are fixedly connected to elastic shielding plates 45. The elastic shielding plates 45 are made of fluororubber. A circular blind hole is provided on the top of the sliding base 41. A circular through hole is provided at the bottom of the circular blind hole of the sliding base 41. The inner surface of the circular through hole at the bottom of the sliding base 41 is connected to a cylindrical tube, and the cylindrical tube is connected to the circular blind hole on the front of the platform 1. A magnetic solid component 42 is fixedly connected to the bottom of the circular blind hole at the top of the sliding base 41. The magnetic solid component 42 includes an electric The magnet assembly 421, the electromagnet assembly 421 is fixedly connected to the bottom of the circular blind hole on the top of the sliding base 41, the electromagnet assembly 421 is electrically connected to the electric control cabinet 2 through a wire, the top of the electromagnet assembly 421 is fixedly connected to an insulating isolation shell 422, the insulating isolation shell 422 is made of POM plastic, and the bottom of the insulating isolation shell 422 is fixedly connected to the bottom of the circular blind hole on the top of the sliding base 41. The front of the platform 1 is fixedly connected to a transmission assembly 43, the transmission assembly 43 includes a servo motor and a threaded rod, and the transmission assembly 43 is slidably connected to the cylindrical tube of the sliding base 41 through the threaded rod. The bottom of the sliding base 41 is connected to a guide tube 44, and the guide tube 44 is located inside the platform 1;

[0036] The sliding base 41 is slidably connected to the flexible splint 5 through a circular blind hole, and the bottom of the sliding frame 32 is fixedly connected to the extrusion stabilizing frame 6.

[0037] During use, before starting the device, the nut stock is placed on the top of the sliding base 41. After it is placed securely, the device is started through the electric control cabinet 2. After the device is started, the electric control cabinet 2 controls the electromagnet assembly 421 to be energized. When the electromagnet assembly 421 is energized, an electromagnetic force is generated. The electromagnetic force attracts the nut stock and promotes the nut stock to adhere to the top of the sliding base 41, thereby increasing the contact area and contact pressure between the top surface of the sliding base 41 and the bottom of the nut stock, thereby increasing the friction between the bottom of the nut stock and the top of the sliding base 41, thereby preventing the nut from slightly displacing during the drilling process. Then, the drill head assembly 33 slides downward under the control of the electric control cabinet 2 and driven by the sliding frame 32 to rotate the hole. During the drilling process, the vibration generated by the drill head assembly 33 during drilling is transmitted to the vibration sensor inside the sliding frame 32 through the drill head assembly 33. The vibration sensor feeds back the detected vibration data to the electric control cabinet 2. The electric control cabinet 2 controls the working state of the servo motor of the transmission assembly 43 based on the feedback data, and then fine-tunes the position of the sliding base 41 forward and backward through the screw to maintain the drilling accuracy of the drill head assembly 33.

[0038] Example 2

[0039] See also Figure 1-6, based on the first embodiment, the present invention provides a technical solution: the number of flexible splints 5 is four and they are evenly distributed on the surface of the sliding base 41, the flexible splint 5 includes an L-shaped slide 51, the L-shaped slide 51 includes a frame 511, the back of the frame 511 is slidably connected to the circular blind hole on the front of the sliding base 41 through a round rod, the back of the round rod of the frame 511 is fixedly connected with a protrusion for limiting the sliding stroke of the frame 511, the cross section of one side of the frame 511 is L-shaped, the top of the frame 511 is provided with two circular through holes, and the circular through holes are symmetrically distributed about the top of the frame 511, the back of the frame 511 is fixedly connected to the back of the circular blind hole of the sliding base 41 through a spring, the bottom of the frame 511 is connected to an electromagnetic coil 512, the bottom of the electromagnetic coil 512 is connected to a Hall sensor 513, the electromagnetic coil 512 and the Hall sensor 513 are both electrically connected to the electric control cabinet 2 through wires;

[0040] An air pump 52 is fixedly connected to the top of the frame 511, and the air pump 52 is electrically connected to the electric control cabinet 2 through a wire. A concave jacket 53 is fixedly connected to the back of the frame 511, and the concave jacket 53 includes a flexible airbag 531. The material of the flexible airbag 531 is fluororubber. The front of the flexible airbag 531 is fixedly connected to the back of the flexible airbag 531. A pressure sensor is provided on the front of the flexible airbag 531. The top of the flexible airbag 531 is connected to the top of the air pump 52 through a metal tube. The back of the flexible airbag 531 is fixedly connected to an elastic extrusion plate 532. The material of the elastic extrusion plate 532 is polyurethane elastomer. A trapezoidal protrusion is fixedly connected to the back of the elastic extrusion plate 532, and the back surface of the elastic extrusion plate 532 is arc-shaped.

[0041] When in use, after the nut raw material is prevented from being on the top of the sliding base 41 in Example 1, the entire device is started by the electric control cabinet 2. While the electromagnet assembly 421 attracts and fixes the nut raw material through electromagnetic force, the air pump 52 is started under the control of the electric control cabinet 2 to discharge air into the flexible airbag 531. As the air is discharged into the flexible airbag 531, the internal pressure of the flexible airbag 531 gradually increases. The air inside the flexible airbag 531 squeezes the flexible airbag 531, causing the flexible airbag 531 to undergo elastic deformation. At the same time, the air inside the flexible airbag 531 also pushes the elastic extrusion plate 532 to move toward the center of the sliding base 41. At this time, the elastic extrusion plate 532 gradually contacts and adheres to the surface of the nut raw material under the combined action of the push of the air inside the flexible airbag 531 and the elastic deformation. As the air is further filled, the surface of the elastic extrusion plate 532 undergoes elastic deformation, further increasing the contact area between the elastic extrusion plate 532 and the surface of the nut raw material, and at the same time, squeezing the surface of the nut raw material to complete the fixation of the nut raw material.

[0042] During the drilling process, the pressure sensor of the flexible airbag 531 transmits the pressure value of its position to the electric control cabinet 2 in real time. The electric control cabinet 2 adjusts the release of the gas inside the flexible airbag 531 at different positions in real time according to the value returned by the pressure sensor, and then adjusts the pressure on the surface of the nut raw material, thereby stabilizing the position of the nut raw material and improving the drilling accuracy. At the same time, part of the vibration generated by the drill bit assembly 33 during the drilling process will be absorbed and offset by the air inside the concave jacket 53 machine.

[0043] Example 3

[0044] See also Figure 1-8 Based on the first and second embodiments, the present invention provides a technical solution: the extrusion stabilizing frame 6 includes:

[0045] The positioning sensing frame 61 includes an octagonal frame body 611, which is fixedly connected to the bottom of the sliding frame 32. A transfer column 612 is fixedly connected to the bottom of the octagonal frame body 611. An elastic column is fixedly connected inside the transfer column 612. The elastic column is made of fluororubber and a metal column is fixedly connected to the outside of the elastic column. There are eight transfer columns 612 and they are symmetrically distributed at the bottom of the octagonal frame body 611. The transfer columns 612 are located at the top of the flexible splint 5. A transfer sleeve 613 is fixedly connected to the surface of the drill assembly 33. The interior of the transfer sleeve 613 is fixedly connected to the outer surface of the metal column of the transfer column 612. The outer diameter of the transfer column 612 is smaller than the inner diameter of the circular through hole at the top of the frame body 511.

[0046] The fixed nozzle 62 is fixedly connected to the bottom of the sliding frame 32. The fixed nozzle 62 includes an upper connecting ring 621. Four circular blind holes are provided on the top of the upper connecting ring 621. The top of the upper connecting ring 621 is connected to the external coolant supply device through the circular blind holes. The top of the upper connecting ring 621 is slidably connected to the bottom of the drill bit assembly 33. The top of the upper connecting ring 621 is fixedly connected to the bottom of the drill bit assembly 33 through a spring. The bottom of the upper connecting ring 621 is connected to the lower spray pressure ring 622. The bottom of the upper connecting ring 621 is connected to the lower spray pressure ring 622. The bottom of the lower spray pressure ring 622 is connected with circular blind holes. The bottom of the circular blind holes at the bottom of the lower spray pressure ring 622 is fixedly connected with an elastic ring. The elastic ring is made of fluororubber. The lower spray pressure ring 622 is located at the top of the sliding base 41.

[0047] During use, when the drill assembly 33 drives the sliding frame 32 to slide down, the transmission column 612 will first be inserted into the electromagnetic coil 512, and then pass through the Hall sensor 513. When the Hall sensor 513 senses the change in magnetic field strength, the Hall sensor 513 transmits the data back to the electric control cabinet 2. The electric control cabinet 2 controls the electromagnetic coil 512 to start. After the electromagnetic coil 512 is started, it generates electromagnetic force to maintain the transmission column 612 inside the circular through hole of the frame 511, and maintains a gap between the inside of the circular through hole of the frame 511 and the outer surface of the transmission column 612, thereby preventing the vibration generated by the drill assembly 33 from being directly transmitted to the L-shaped slide 51 and the concave sleeve 53. As the drill assembly 33 slides further down, the elastic ring at the bottom of the lower injection ring 622 first contacts and squeezes the top of the nut raw material. As the drill assembly 33 continues to slide down, the elastic column of the transmission column 612 contacts and elastically deforms the top of the platform 1, and the upper connecting ring 621 and the drill assembly 33 slide relative to each other. At the same time, the drill rod of the drill bit assembly 33 begins to drill a hole on the top of the nut raw material. During this process, the external coolant supply device discharges coolant into the fixed nozzle 62. When the coolant reaches the bottom, the coolant flow applies additional pressure to the top of the nut raw material. When the drilling is completed and the hole is withdrawn, the debris generated by the drill rod of the drill bit assembly 33 is attracted by the electromagnet assembly 421. However, since the insulating isolation shell 422 isolates the electromagnet assembly 421 from the outside world, some of the debris is adsorbed on the outer surface of the insulating isolation shell 422. When the drill rod leaves the nut raw material, the bottom of the lower spray pressure ring 622 is separated from the surface of the nut raw material, and the coolant is released and sprayed on the surface of the nut raw material, flushing the surface of the nut raw material and the inside of the hole drilled by the drill rod of the drill bit assembly 33. At this time, the electric control cabinet 2 controls the electromagnet assembly 421 to be powered off, the electromagnetic force disappears, and the coolant flushes the debris still on the surface of the insulating isolation shell 422. Driven by the coolant, the debris falls into the interior of the platform 1 along the guide pipe 44 to complete the flushing.

[0048] During the process of Example 1 and Example 2, the vibration generated by the drill bit assembly 33 during drilling is transmitted to the transmission column 612 through the transmission sleeve 613, and then transmitted to the surface of the table 1 through the elastic column inside the transmission column 612, loosening the dust on the surface of the table 1. The loosened dust is blown away from the surface of the table 1 by the blower on the top of the table 1. During this process, the elastic shielding plate 45 blocks the rectangular through hole portion on the top of the table 1, thereby preventing dust from adhering to the surface of the transmission assembly 43 and affecting the transmission.
