Detailed Description
The technical solution in the examples of the present invention will be clearly and completely described below with reference to the accompanying drawings in the examples of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the embodiment of the present invention provides an accurate fixture for drilling angle steel of electric switch machine, which is fixed on an internal combustion rail drilling machine, and is characterized in that the fixture includes a fixture fixing device 8, a flexible space of a drill bit 1 of the internal combustion rail drilling machine is left in the middle, fixing screws 2 of the fixture installed on the internal combustion rail drilling machine are distributed at four corners, two upper square bumps 10 are provided on the upper portion for supporting the upper edge of the narrow airfoil of the angle steel 9, and two lower square bumps 11 are provided on the lower portion for supporting the folding angle of the narrow airfoil of the angle steel 9.
Including the long airfoil locating piece 3 of angle steel, be located 8 lower parts of anchor clamps fixing device, have a square draw-in groove, its degree of depth is slightly dark than the long airfoil width of angle steel 9, and its height is slightly higher than the long airfoil thickness of angle steel 9, just in time blocks the long airfoil of angle steel, withstands the narrow airfoil of angle steel 9 with the circular bump 12 in the lower part of the anchor clamps body 7 simultaneously, realizes spacing and fixed of angle steel 9 level and vertical direction to guarantee the stability of angle steel installation.
