Description

Technical Field

[0001] The invention relates to the technical field of magnetic base drilling equipment, in particular to a magnetic base drilling machine for small-diameter deep holes. Background Art

[0002] The magnetic drill, also known as the magnet drill or the iron-absorbing drill, generates a magnetic field when the power is turned on, and the electromagnet in the base of the magnetic drill is adsorbed on the steel part. Then the magnetic drill motor runs at high speed to drive the drill bit to drill holes or thread the steel plate. It is widely used in metal processing.

[0003] Publication No.: CN116689815A discloses a magnetic base drill for small-diameter deep holes, including a magnetic suction base, a sliding drill, a reduction drive assembly and an auxiliary telescopic bracket. The magnetic suction base is in the shape of an elongated strip as a whole, one end of which is a magnetic suction part for fixing the magnetic suction base on a metal workpiece, and a handle is provided at the other end of the magnetic suction base. The sliding drill includes a drill body and a drill bit, the drill bit is horizontally detachably connected to the drill body, the drill body is slidably connected to the top of the magnetic suction base, the reduction drive assembly is arranged on the magnetic suction base, and the reduction drive assembly is used to drive the drill body to slide slowly along the axial direction of the drill bit, and the auxiliary telescopic bracket includes a multi-section telescopic bracket, a sliding limit mechanism, a locking mechanism, an unlocking mechanism and an elastic sleeve. The device achieves that the relative position of the elbow nozzle and the end of the drill bit does not change before and after drilling, simulating a manually held spray gun, thereby greatly reducing manual labor intensity. However, in actual use, when the device and existing equipment are magnetically fixing metal surfaces, impurities such as rust exist on some metal surfaces, resulting in reduced flatness of the metal surface, which reduces the actual magnetic fixing effect of the magnetic base drill. Moreover, since most rust is ferric oxide, this substance cannot be adsorbed by the electromagnet, and rust covering the metal surface will reduce the adsorption capacity of the electromagnet on the metal surface, resulting in unstable adsorption effect of the magnetic base drill during use. The adsorption stability of the magnetic base drill has room for further improvement. Summary of the invention

[0052] Working principle: Place the drilling rig body and the equipment body 2 on the surface of the metal plate that needs to be punched. In the initial state, the second gear is at the top of the first gear, and the meshing rod 36 is at the top of the bevel gear 54. Use the control center 10 to turn on the first linear drive component 35. The first linear drive component 35 is turned on to push out and move the first output rod 350 downward. The first output rod 350 moves downward to drive the first toothed disc 351 and the meshing rod 36 to move downward until the meshing rod 36 is meshed and connected with the bevel gear 54. Then use the control center 10 to turn on the first rotary drive component 30 inside the drive device 3. The first rotary drive component 30 is turned on to drive the first rotating shaft 31 to rotate. The first rotating shaft 31 rotates to drive the first movable wheel 32 to rotate, the first movable wheel 32 rotates through the movable belt 33 and the first shaft rod 340 to drive the second movable wheel 34 to rotate, the second movable wheel 34 rotates to drive the first linear drive assembly 35 to rotate, the first linear drive assembly 35 is turned on to drive the first output rod 350, the first toothed disc 351 and the meshing rod 36 to rotate, the meshing rod 36 rotates to drive the bevel gear 54 to rotate, the bevel gear 54 rotates to drive the screw rod 540 to rotate, the screw rod 540 rotates under the rectangular restriction of the partition plate 51 and the through rod 55 to drive the through rod 55 to move toward the inner right side of the fixing device 5, The through rod 55 moves to drive the mounting part 550 and the grinding roller 552 to move. At this time, the grinding roller 552 is in the falling area of ​​the electromagnetic plate 44. The control center 10 is used to reset the first linear drive component 35, the first output rod 350, the first gear plate 351 and the meshing rod 36. At this time, the meshing rod 36 is no longer in contact with the bevel gear 54. Then the control center 10 is used to start the second rotary drive component 52. The second rotary drive component 52 is turned on to drive the second rotating shaft 520 to rotate. The second rotating shaft 520 rotates to drive the rotating arm 521 to rotate. The rotating arm 521 rotates to drive the rotating rod 522 to make a circular motion. The rotating rod 522 The circular motion drives the return groove plate 53 to perform linear reciprocating motion, and the linear reciprocating motion of the return groove plate 53 drives the fixed plate 530, the rotating column 531, the bevel gear 54, the screw 540, the through rod 55, the mounting part 550, and the grinding roller to perform linear reciprocating motion. The grinding roller 552 performs linear reciprocating motion to grind the surface of the metal plate to prevent the debris and rust on the metal surface from affecting the adsorption capacity of the electromagnet when the magnetic base drilling machine is directly turned on, thereby reducing the fixing effect of the device. In this process, the closing plate 580 always closes the electromagnetic plate 44 to prevent rust debris from adhering to the surface of the electromagnetic plate 44, thereby improving the stability of the device and facilitating user use;

[0053] When the mounting member 550 makes a linear reciprocating motion, the movement of the mounting member 550 drives the two movable rods 553 and the piston plate 554 to make a linear reciprocating motion in the gas delivery bin 56. When the two movable rods 553 and the piston plate 554 move to the right, the air pressure inside the two gas delivery bins 56 increases, and the air inside the gas delivery bins 56 is transmitted to the gas delivery plate 59 through the output pipe 560. A plurality of nozzles are fixedly connected to the gas delivery plate 59. The interior of the gas delivery plate 59 is pre-installed with an inclined guide plate, and the air inside the gas delivery plate 59 is Then, the air is sprayed into the grinding area of ​​the grinding roller 552 through the nozzle and the guide plate to prevent the rust after grinding from adhering to the surface of the electromagnetic plate 44, reducing the contact area between the electromagnetic plate 44 and the metal plate, thereby reducing the fixing effect between the electromagnetic drill and the metal plate. When the two movable rods 553 and the piston plate 554 move to the left, the internal air pressure of the two air supply bins 56 changes again, and the air is filled into the air supply bins 56 through the air supply plate 59 and the output pipe 560, thereby improving the adsorption stability of the device and facilitating the use of the user.

[0054] After the grinding roller 552 is processed, the control center 10 is used to reset it, and then the control center 10 is used to start the first linear drive component 35, and the first linear drive component 35 drives the first output rod 350, the first toothed disc 351, and the meshing rod 36 to move upward so that the first toothed disc 351 and the second toothed disc 570 are meshed with each other. At this time, similarly, when the first rotary drive component 30 rotates the first linear drive component 35 and the first toothed disc 351 through the first rotating shaft 31, the first toothed disc 351 drives the second toothed disc 570 to rotate, and the rotation of the second toothed disc 570 drives the tooth plate 571 to move toward the right end, and the movement of the tooth plate 571 drives the closing plate 580 to move toward the inner right side of the fixing device 5. After the closing plate 580 moves, it no longer blocks the electromagnetic plate 44. At this time, the second linear drive component can be normally started by the control center 10. 40 pushes out the second output rod 41, and the movement of the second output rod 41 drives the connecting piece 42, the baffle plate 43, and the electromagnetic plate 44 to move. When the electromagnetic plate 44 moves to the surface of the metal plate, the baffle plate 43 just completely blocks the gas transmission plate 59, and then the control center 10 is used to open the electromagnetic plate 44 to adsorb the surface of the metal plate, and the drilling rig body 1 performs the drilling process normally. After the processing is completed, when the electromagnetic plate 44 and the closing plate 580 are reset, since the closing plate 580 is in contact with the initial state of the electromagnetic plate 44, the closing plate 580 can clean the bottom surface of the electromagnetic plate 44 after the bottom of the electromagnetic plate 44 is reset, so as to avoid some debris from adhering to the surface of the electromagnetic plate 44 and reduce the contact area between the electromagnetic plate 44 and the metal plate, thereby reducing the fixing effect between the electromagnetic drilling rig and the metal plate, improving the stability of the device adsorption, and facilitating user use.
