Description
Technical field
The utility model relates to rail technical field, particularly a kind of rail bolt hole chamfered edge drilling tool.
Background technology
The bolt hole of hole rail is not when there is no chamfered edge, the concentrated stress producing can cause rail fracture, waste for fear of rail, need to carry out chamfered edge to the bolt hole of rail, existing rail bolt hole chamfered edge electric drill only utilizes a blade to carry out chamfered edge, has following two problems: the one, and the chamfered edge degree of depth is inhomogeneous; The 2nd, chamfered edge blade is short service life, affects chamfered edge quality.
Summary of the invention
The purpose of this utility model is to provide a kind of rail bolt hole chamfered edge drilling tool simple in structure, easy to use.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of rail bolt hole chamfered edge drilling tool, comprise blade, chamfered edge head and drill body, described blade one end is provided with installing hole, the other end is provided with cutter head, blade one end is passed in the mounting groove that installing hole is fixed on chamfered edge head inside by set bolt, the cutter head of the blade other end is exposed at the outside of the first end of chamfered edge, and the chamfered edge head other end is connected with drill body by electric drill main shaft.
Described blade has two.
Described cutter head is triangular structure.
Described chamfered edge head and electric drill spindle thread link together.
Compared with prior art, the beneficial effects of the utility model are:
A rail bolt hole chamfered edge drilling tool, has little, simple in structure, easy to use, the practical feature of volume, has accomplished that the chamfered edge degree of depth is even, effectively improves chamfered edge quality and blade service life.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further illustrated:
As shown in FIG. 1 to 3, a kind of rail bolt hole chamfered edge of the utility model drilling tool, comprise blade 1, chamfered edge head 2 and drill body 3, described blade 1 one end is provided with installing hole 4, the other end is provided with cutter head 5, blade 1 one end is fixed in the mounting groove 7 of chamfered edge head 2 inside through installing hole 4 by set bolt 6, and the cutter head 5 of blade 1 other end is exposed at the outside of chamfered edge head 2 one end, and chamfered edge head 2 other ends are connected with drill body 3 by electric drill main shaft 8; Described blade 1 has two; Described cutter head 5 is triangular structure; Described chamfered edge head 2 is threaded togather with electric drill main shaft 8.
While using the utility model, start drill body 3, drill body 3 drives chamfered edge head 2 to rotate by electric drill main shaft 8, and 1 pair of rail bolt hole of chamfered edge head 2 band cutting blades carries out chamfered edge; According to hole rail diameter of bolt hole size, can change chamfered edge head 2, meet the production of different cultivars.
Above described in be only basic principle of the present utility model, not the utility model is imposed any restrictions, everyly according to the utility model, it is carried out to equivalent variations and modification, all within the category of the art of this patent protection scheme.
