Embodiment Construction
[0010] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation of the protection scope of the present invention.
[0011] like figure 1 Shown: a kind of hand-held EPC electric drilling device of the present invention, comprises electric hand drill 1, clamps drill handle 2 on the described electric hand drill 1, and the surface of drill handle 2 is engraved with the scale mark 3 that represents length, in The drill shank 2 is covered with a positioning plate 4, and the drill shank 2 and the positioning plate 4 are a dynamic fit. The front end of the drill shank 2 is a top 9, and the rear part of the top 9 is a cross milling cutter 8 fixedly connected with the drill shank 2. The positioning plate 4 is disc-shaped, and four bosses 6 are evenly distributed around...

The invention discloses a hand-held electric drilling device for an evanescent mode. The hand-held electric drilling device comprises an electric hand drill; a drill handle is clamped on the electric hand drill; a scale for representing length is carved on the surface of the drill handle; a locating plate is further sleeved on the drill handle; the drill handle is dynamically matched with the locating plate; the front end of the drill handle is a tip; a crossed milling cutter which is fixedly connected with the drill handle is arranged at the rear part of the tip; the locating plate is in a circular plate shape; four bosses are uniformly distributed around the locating plate; each boss is provided with a locating pin; and four circular holes for observing drill cuttings are uniformly distributed at the middle part of the locating plate. According to the embodiment of the hand-held electric drilling device, the positions of the drilled holes on the evanescent mode are accurate; in addition, the vertical degree between the holes and the surface of the evanescent mode can be guaranteed; and the depth of blind holes can be effectively controlled.
Description
technical field [0001] The invention relates to the field of electric tools, in particular to a hand-held lost foam electric drilling device. Background technique [0002] After lost foam molding, it is often necessary to drill lightening holes and / or bushing holes, overcast nut holes, etc. The existing technology is to use hand electric drilling, which often leads to drilling deviation, inaccurate hole positions, and inaccurate depth of drilled blind holes. accurate phenomenon. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a hand-held EPC electric drilling device, so as to avoid the phenomenon of drilling deviation, inaccurate hole position and inaccurate depth of drilling blind holes when drilling on EPC. [0004] In order to achieve the above object, the technical solution of the present invention is: a hand-held lost foam electric drilling device, including a hand electric drill, the drill handle is c...
