Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a drilling device for plate processing. Background Art

[0002] During the sheet metal processing process, drilling is required to meet specific usage requirements. When drilling composite sheets, due to the multi-layer composite composition of the sheets, fibers that are not promptly removed from the different sheets are prone to being lost during drilling. This can cause wear on the drill hole and lead to burrs inside the hole, impacting the performance of the drill. Furthermore, during continuous drilling, delamination can occur between the different sheets due to the axial stress of the drill bit, affecting the normal use of the sheet metal. Therefore, a drilling device for sheet metal processing is proposed. Summary of the Invention

A guide rail 4 is fixed to both sides of the upper surface of the base 1, and a "T"-shaped guide groove 401 is opened in the middle part of the outer surface of the guide rail 4 on the side close to each other. The guide rail 4 is slidably inserted and installed with a guide block 5 through the inner surface of the guide groove 401. A bracket 502 is commonly fixed to the middle part of the outer surface of the guide block 5 on the side close to each other. A positioning hole 501 is opened in the middle part of the upper surface of the guide block 5, and the positioning hole 501 is sleeved on the outer surface of the positioning screw 103;

[0029] A guide ring 503 is fixedly provided on the lower surface of the bracket 502, and a slide groove is provided on the lower surface of the guide ring 503. A plurality of connecting plates 504 are movably installed on the guide ring 503 through the inner surface of the slide groove. A motor 6 is fixedly installed through the middle part of the upper surface of the bracket 502, and a drill rod 7 is fixedly installed on the output end of the motor 6. A drill bit 701 is fixedly provided on the output end of the drill rod 7. A plurality of discharge holes 702 are provided in a fan shape on one side of the output surface of the drill bit 701. A grinding cylinder 703 is fixedly provided on the outer surface of the drill rod 7 near the output end, and a plurality of diversion holes 704 are evenly provided on the outer surface of the grinding cylinder 703 away from the discharge holes 702. A diversion cylinder 705 is fixedly provided on the outer surface of the other end of the drill rod 7. A fan-shaped spacer 706 is provided on the inner surface of the grinding cylinder 703 and the diversion cylinder 705 near the diversion hole 704. The other side of the spacer 706 is connected to the outer surface of the drill rod 7.

[0030] Two groups of conduits 10 of different diameters are fixedly installed on the lower parts of both sides of the outer surface of the guide tube 705. A micro-fan 8 is fixedly installed on the other end of one group of large-diameter conduits 10, and a liquid storage chamber 9 is fixedly installed on the other end of the other group of small-diameter conduits 10. A clamping block 11 is protruded and fixed in the middle of the side close to the outer surface of the micro-fan 8 and the liquid storage chamber 9. The clamping block 11 is clamped and installed in the connecting plate 504. The micro-fan 8 and the discharge hole 702 are on the same side, and the liquid storage chamber 9 and the guide hole 704 are on the same side.

[0031] When the present invention is in use, first, according to the position where the hole is required to be drilled in the plate, the first limiting rail 2 and the second limiting rail 201 provided at both ends of the base 1 are unfolded to the side position of the plate accordingly, and engage with the side edge of the plate, and tighten the locking bolt 102 clockwise to complete the fixation of the first limiting rail 2 and the second limiting rail 201. At this time, the base 1 can be fixed correspondingly to the drilling position of the plate. In this case, the corresponding two sets of adjusting bolts 301 can be screwed clockwise at the same time to control the pressing block 302 to approach the plate and contact it. Under the continuous screwing of the adjusting bolts 301, the extrusion positioning around the drilling position of the plate is achieved to ensure the adhesion between different plates during the drilling process. At the same time, the gap between the pressing blocks 302 facilitates the dispersion of the axial stress carried by the drill bit 701, thereby avoiding the delamination problem of the plate caused by drilling.

[0032] When the pressing block 302 completes the extrusion and positioning of the plate, the motor 6 can be started to control the drill rod 7 to drive the drill bit 701 to rotate. When the drill bit 701 is in the rotating state, the guide block 5 is controlled to move up and down along the guide rail 4. During the descending process of the guide block 5, the bracket 502 is synchronously lowered to drive the drill rod 7 toward the plate. When the drill bit 701 contacts the plate, the drilling operation can be carried out. At the same time, during the drilling operation, the positioning screw ring 104 sleeved on the outer surface of the positioning screw 103 can be adjusted to a suitable position so that the distance between it and the guide block 5 is equivalent to the depth of the plate drilling. When the guide block 5 descends to contact with the positioning screw ring 104, the required drilling depth can be reached and the drilling operation is completed.

[0033] Secondly, during the drilling process, the micro-blower 8 can be started to cooperate with the conduit 10 to perform negative pressure extraction on the interior of the guide cylinder 705, so that the sheet material fibers generated by the drill bit 701 in the drilling process are sucked into the guide cylinder 705 through the discharge hole 702 opened on the drill bit 701 to complete the rapid discharge of the sheet material fibers, thereby reducing the sheet material fiber content in the drill hole. At the same time, as the drill bit 701 continues to advance, the grinding cylinder 703 will rotate and grind the inner wall of the drill hole as the drill rod 7 rotates, thereby improving the flatness of the drill hole. In the process of grinding the drill hole by the grinding cylinder 703, the liquid storage chamber 9 can store lubricating liquid inside. With the help of the conduit 10 and the guide cylinder 705, the lubricating liquid can be guided into the grinding cylinder 703 and discharged to the surface of the grinding cylinder 703 through the guide hole 704, further reducing the resistance of the grinding cylinder 703 during the drilling and grinding process, thereby improving the grinding effect.

[0034] Finally, since the micro fan 8 and the liquid storage chamber 9 are connected to the connecting plate 504 through the clamping block 11, when the micro fan 8 and the liquid storage chamber 9 rotate synchronously with the drill rod 7, the connecting plate 504 can rotate synchronously in the guide ring 503, thereby maintaining stable support for the micro fan 8 and the liquid storage chamber 9 and maintaining their operating effect.

[0035] The above are merely examples of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
