For achieving the above object, the utility model provides a kind of interior cubic inserted joint pipe female fixing device for drilling, the cross section of described interior cubic inserted joint pipe female is square, and described interior cubic inserted joint pipe female fixing device for drilling is provided with fixedly block set, tetragonal body fixed leg and set bolt; Described fixedly block set is set to positive tetragonal body, be provided with cylindrical cavity in the middle part of the fixedly block set of positive tetragonal body, the fixedly block set base of the axis of cylindrical cavity and positive tetragonal body is parallel, the top right side of the fixedly block set of positive tetragonal body is apart from the front end of line of the fixedly block set of positive tetragonal body and apart from the equidistant pilot hole that an equal length respectively is set of fixed cover base rear end line of positive tetragonal body, and the length of pilot hole is the distance bottom the cylindrical cavity greater than fixing block set top; Described tetragonal body fixed leg is provided with cylinder base and tetragonal body sleeve column, the diameter of cylinder base equals the internal diameter of cylindrical cavity, the cylinder base is welded and fixed with the cylindrical cavity port in the left side of the fixedly block set of positive tetragonal body, the upper end of cylinder base and tetragonal body sleeve column bottom are welded and fixed, and the middle part of tetragonal body sleeve column is provided with internal thread; Described set bolt is provided with screw rod and pad, and screw rod is provided with the external screw thread corresponding with the internal thread at tetragonal body sleeve column middle part, and the diameter of pad is greater than the square diagonal line length of described interior cubic inserted joint pipe female cross section.
The center bottom of the fixedly block set of described positive tetragonal body is provided with the lock chamber vertical with cylindrical cavity.
The length of described pilot hole equals the height of the fixedly block set of positive tetragonal body.
The utility model beneficial effect is: interior cubic inserted joint pipe female fixing device for drilling of the present utility model is simple in structure, easy to make, with low cost; Interior cubic inserted joint pipe female can be punched along pilot hole by the drill bit of tetragonal body fixed leg and the fixing rear electric drill of set bolt, this can guarantee on the one hand that cubic inserted joint pipe female is got in each pin hole site meets product requirement, has improved yield rate; Drill bit is stressed when internal cubic inserted joint pipe female is punched in pilot hole on the other hand is more uniform, thereby greatly reduces the probability that drill bit is interrupted, and increases work efficiency, and has also reduced the production cost of enterprise.
Below in conjunction with accompanying drawing, interior cubic inserted joint pipe female fixing device for drilling of the present utility model is described further.
