The invention discloses a high-speed trepanning drilling file and a drilling filing method, and relates to the high-speed trepanning drilling file. The traditional punching manner is slow in trepanning speed, the punching effect is poor, and the high-speed trepanning drilling file comprises a triangular pyramid body, an inner cavity of the triangular pyramid body is provided with a connection block in an inverted stair landing shape, the upper end of the connection block is fixedly connected with a bearing, the inner ring of the bearing is fixedly connected with the lower end of a thread rod,the upper end of the thread rod is provided with a key groove used for connecting with a drill machine, three connection arms corresponding to grinding blocks in position are evenly arranged on the side wall of the connection block, the connection arms and the connection block are rotatably connected through rotating shafts, ends, away from the connection block, of the connection arms are rotatably connected with the grinding blocks through rotating shafts, the width of the connection arms is matched with the width of a rectangular cavity, and a fixing device used for fixing a thread rod is arranged on a thread pipe. The file has the beneficial effects that during operation, trepanning speed is high, and the punching effect is good.
Description
technical field [0001] The invention relates to the technical field of drill files, in particular to a high-speed hole-opening drill file. Background technique [0002] The traditional drilling method is to use a drill to drill, and then use a file to grind. This method has a slow drilling speed, poor drilling effect, and the size of the drilled hole cannot be adjusted. , we propose a high-speed hole drilling file. Contents of the invention [0003] The purpose of the present invention is to solve the disadvantages of slow hole opening speed, poor drilling effect, non-adjustable size of drilled holes and limited use in the prior art, and proposes a high-speed hole drilling file. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] Design a kind of high-speed perforating drill file, comprise triangular pyramid body, the outside of described triangular pyramid body is respectively provided with first grindi...
