Abstract
The utility model relates to a chamfering tool. The chamfering tool comprises a chamfering tool and a pull rod, wherein a center hole is arranged in the chamfering tool, and the pull rod is inserted into the center hole from the small end of the chamfering tool and is fixedly connected with the center hole as a whole; the pull rod is also provided with an operating handle movably connected; and the chamfer angle of the chamfering tool ranges from 45 degrees to 60 degrees. The chamfering tool is simple in structure, easy to produce and convenient to operate; the pull rod of the chamfering tool penetrates through the back side of a flange mounting hole reversely, thereby avoiding limit of semi-closed space to operation; burs at a hole of the back side can be removed by rotating the handle three to five times, the burs are removed cleanly and the effect is good, and the quality of products is stable; and the chamfering tool is time-saving and effort-saving, the working efficiency is improved by more than 5 times, and the manufacturing cost of the products can be lowered.
Description
Technical field
The utility model relates to a kind of cutter, is specifically related to a kind of chamfering tool.
Background technology
For the flange mounting hole on the expansion shape part, the back side of installing hole is in hemi-closure space, adopt round file cutter, the manual burr of removing on the flange mounting hole of triangular scraper, limited by the operating space, burr is removed not thorough, and can only remove the burr at place, flange installed surface aperture, can not remove the burr at place, aperture, the flange back side, the quality of part can not be guaranteed; Use the burr on the angle scraper removal aperture, although can remove simultaneously the burr on two sides, aperture, remove large, the inefficiency of time length, labour intensity of burr, cause the manufacturing expense of part high.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, provide a kind of simple in structure, easy to manufacture, easy to use, remove effective, the fireballing chamfering tool of burr at place, aperture, the flange mounting hole back side.
Chamfering tool of the present utility model comprises rose reamer and pull bar, it is characterized in that: described rose reamer is provided with centre bore, and pull bar inserts in the centre bore and is solidly connected from the small end of rose reamer and is integral; Also be provided with the operating grip of flexible connection on the described pull bar.
In order better to realize above-mentioned purpose: the chamfering of described rose reamer is 45
o～60
o
Chamfering tool of the present utility model, simple in structure, make easily, easy to operate, the pull bar of rose reamer oppositely passes from the back side of flange mounting hole, avoid hemi-closure space to the restriction of operation, by turning handle 3～5 times, can remove the burr on the aperture, the back side, removal effect is good, the steady quality of product; Time saving and energy saving, operating efficiency improves more than 5 times, has reduced the manufacturing expense of product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is enforcement illustration of the present utility model.
Among the figure: 1, rose reamer, 2, pull bar, 3, operating grip, 4, part, a, chamfering.
The specific embodiment
Chamfering tool of the present utility model comprises rose reamer 1 and pull bar 2.Rose reamer 1 is provided with centre bore, and pull bar 2 inserts in the centre bore also integrally welded from the small end of rose reamer 1; Pull bar 2 is provided with the operating grip 3 of flexible connection; The chamfering a of rose reamer 1 is 45
o
During use, operating grip 3 on the pull bar 2 is taken off, pull bar 2 oppositely passes flange mounting hole from the flange back side of part 4, load onto operating grip 3 at pull bar 2 again, tension operating grip 3 makes the blade of rose reamer 1 be adjacent to the aperture, the back side of flange mounting hole, rotating operation handle 3, pull bar 2 drive rose reamer 1 and rotate the burr that can remove on the aperture, the flange mounting hole back side.
