Abstract
The utility model discloses a cutter for removing deep hole inner edge burrs. The cutter comprises a cutter rod (1) and blades (2), and is characterized in that one end of the cutter rod (1) is provided with a partition groove (3) which splits one end of the cutter rod (1) to form two elastic rods (4), the blades (2) are fixed on the head portion of each elastic rod (4), and each blade (2) is arc-shaped. The cutter has the advantages of being simple in structure and convenient to use, and greatly improving work efficiency of burr removing.
Description
Technical field
It is interior to hole machining tool technical field that the utility model relates to machinery industry, relates in particular to a kind of cutter for removing deep hole inner lip burr.
Background technology
At mechanical processing industry, there are a lot of workpiece need to be to its processing of carrying out through hole, ganging up the hole, after this class hole processed by drilling and milling machine, the peristoma in its hole can stay a lot of burrs, must be removed, and could satisfy the product technology requirement.How to remove? for the removal of expression at the burr of the hole of surface of the work outer lip, it should be the easier thing of part, but for the hole of depths in workpiece, especially some is shaped with the workpiece of ganging up the hole, such as the removal of the burr of the inn edge of ganging up the hole on air valve, the oil cylinder class workpiece, it really not the easy thing of part.At present to the burr removing method on the inn edge mainly be according to inn towards selecting different cutters, generally adopt bar rod-type file for inn aperture burr inwardly, bar rod-type file puts in the hole, and then with file banking, file and inn edge oblique are rubbed back and forth and the circumferentially mobile friction along the aperture, to remove the burr of aperture edge; And generally adopt the triangle scraper for inn aperture burr outwardly, and this triangle scraper is comprised of the handle of a knife scraper, and scraper is triangle, is fixed on an end of handle of a knife.When removing burr, this cutter is put in the aperture that makes triangular scraper drop on this hole from the hole, rotate back and forth handle of a knife and make scraper at the burr that strikes off back and forth on the edge of aperture on the edge of aperture.This shows that existing mode and the cutter of removing deep hole inner lip burr is all relatively backward, inefficiency not only, and in operating process, slightly do not note, also hole wall can be scratched, make workpiece become substandard products or scrap.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model is, a kind of cutter for removing deep hole inner lip burr is provided, and this cutter has simple in structure, and is easy to use, can significantly improve the advantage of removing the burr operating efficiency.
(2) technical scheme
A kind of cutter for removing deep hole inner lip burr comprises knife bar and blade, it is characterized in that an end of described knife bar is provided with an interval trough, and interval trough forms two elastic rods with an end bifurcated of knife bar, and described blade is fixed on the elastic rod head.
Described blade is arranged to the arc surface shape.No matter be arranged to the arc surface shape, be to inn hole inwardly, or to inn hole outwardly, its blade part can both form close contact to the aperture edge, and reaches quick removal burr, and aperture edge surface smoothing,
(3) beneficial effect
Compared with prior art, because the utility model arranges the head of two elastic rods with blade, during use, as long as with finger two elastic rods are inwardly taken the photograph and to close, the blade part diameter is much smaller than the aperture, and the operator is attention a little diligently, cutter enters or withdraws from the position, hole, and the probability that blade scratches hole wall reduces greatly, after blade part is crossed the hand-hole position, relieving is taken the photograph and is closed, blade part is greater than the aperture, at this moment, as long as rotate knife bar by hand, blade part rotates with this, and blade just can be got rid of the burr of aperture edge soon.Operating efficiency improves greatly.And between the letter of the utility model structure, easy to operate.
Description of drawings
Fig. 1 is the structural representation of a kind of cutter for removing deep hole inner lip burr of the utility model.
Fig. 2 is a kind of a kind of use state of cutter reference view for removing deep hole inner lip burr of the utility model.
Shown in the figure, 1, knife bar, 2, blade, 3, interval trough, 4, elastic rod.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of cutter for removing deep hole inner lip burr of the present utility model, comprise knife bar 1 and blade 2, it is characterized in that, one end of described knife bar 1 is provided with an interval trough 3, interval trough 3 forms two elastic rods 4 with an end bifurcated of knife bar 1, and described blade 2 is fixed on elastic rod 4 heads.Described blade 2 is arranged to the arc surface shape.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. cutter of be used for removing deep hole inner lip burr, comprise knife bar (1) and blade (2), it is characterized in that, one end of described knife bar (1) is provided with an interval trough (3), interval trough (3) forms two elastic rods (4) with an end bifurcated of knife bar (1), and described blade (2) is fixed on elastic rod (4) head.
2. a kind of cutter for removing deep hole inner lip burr as claimed in claim 1 is characterized in that described blade (2) is arranged to the arc surface shape.
