Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a protective structure for drilling with a laser generator. Background Art

[0002] Using a drill to make a hole in a solid material is called drilling. The hole processing of various parts, except for a part that is completed by lathes, boring machines, milling machines, etc., a large part is completed by fitters using drilling machines and drilling tools (drills, reamer drills, reamers, etc.). When drilling on a drilling machine, the drill should generally complete two movements at the same time: the main movement, that is, the rotation of the drill around the axis (cutting movement); the auxiliary movement, that is, the linear movement of the drill along the axis toward the workpiece (feed movement). When drilling, the processing quality is affected mainly due to the shortcomings of the drill structure, and the processing accuracy is generally below IT10 level.

[0003] Chinese patent CN 216178708 U discloses a laser generator housing drilling fixture. The utility model discloses a laser generator housing drilling fixture. One end of a connecting column away from a fixed plate is movably inserted into the top of the fixture. A groove is provided inside the fixture on the outer side of the connecting column. Slide grooves are provided on both sides of the groove. One end of the connecting column is fixedly connected with two sliders slidably connected to the inside of the slide groove. A telescopic spring is fixedly connected between the bottom of the connecting column and the groove. The fixed plate is driven to move downward by controlling the extension of the piston rod of the hydraulic cylinder so that the fixture contacts the top of the housing plate, and the housing plate is pre-fixed to avoid direct use of the fixture for fixing, so that the position of the housing plate is offset. After the drilling is completed, the piston rod of the hydraulic cylinder is controlled to be reset so that the drill bit is separated from the housing plate, and the fixture still contacts the outer side of the housing plate to avoid the housing plate position offset during the reset of the drill bit, causing the housing plate to deform.

The above patent can only process the debris but cannot process the dust. If the dust is allowed to float in the air, it will not only pollute the environment but also endanger the health of people.
