Description

Vacuum suction drilling device and manufacturing method thereof

The present invention relates to a drilling apparatus and a method of manufacturing the same, and more particularly to a vacuum type drilling apparatus and a method of manufacturing the same.

Referring to FIG. 1 , a conventional drill bit 1 includes a clamping portion 11 , a chip removing portion 12 extending along a longitudinal direction of the clamping portion 11 , and a coupling portion 12 opposite to the cutting portion 12 opposite to the clamping portion 11 is a drill tip 13 at one end. The chip evacuation portion 12 has a chip flute 121 in a spiral shape. When the cement structure 100 is drilled by the drill bit 1, most of the debris generated by the drill attack will be discharged along the chip flute 121, but some debris and dust remain in the drilled hole 101. Therefore, the hole 101 is still required to be cleaned after drilling.

In order to achieve the purpose of eliminating the hole cleaning step after drilling, as shown in FIG. 2, a conventional dust suction drilling device 2 includes a hollow drilling unit 21 and a surrounding chamber 220. Connected to the communication unit 22 of the drilling and attack unit 21. The drilling and attack unit 21 includes a drill bit 211 and a rod 212 extending integrally rearward from the drill bit 211. The drill bit 211 has at least one through hole 201 in a through shape, and the rod body 212 has at least one through hole 202 in a through shape. The connecting unit 22 is sleeved on the rod 212, and the chamber 220 is in communication with the through hole 202.

When drilling with the dust suction drilling device 2, the drill bit 211 of the drilling and attack unit 21 rotates with the rod body 212, and the debris generated by the drill bit 211 is powered by the suction device 23. It is sucked from the opening 201 and is removed by the suction device 23 through the through hole 202 in the rod 212, so that the drill bit 211 does not need to be designed with a chip evacuation structure. In addition, since the dust suction drilling device 2 can remove the debris at the same time when drilling, the subsequent cleaning step is not required.

However, since the drill bit 211 is directly subjected to an external force when performing a drilling attack, the drill bit 211 of the drilling and attack unit 21 may be damaged faster than other components. However, when the drill bit 211 is damaged, the dust suction drilling device 2 cannot be normally operated to perform drilling, and the entire group of the dust suction drilling device 2 must be directly replaced.
