Abstract
The utility model provides a reusable machine reamer. According to the technical scheme, the reusable machine reamer comprises a reamer cutting portion, a copper sheet, a countersunk bolt, a reamer neck and a reamer taper shank, wherein the reamer cutting portion, the reamer neck and the reamer taper shank are cast into a whole, the reamer cutting portion and the reamer neck are equally cut to the middle section of the neck along the shaft axis of the reamer cutting portion and the reamer neck, the copper sheet is arranged in a cut line gap of the reamer cutting portion, the cut line gap of the reamer cutting portion is close to a blade, the thickness of the copper sheet is 0.03-0.06mm, the reamer neck is provided with a thread through hole in the direction perpendicular to a cut line, and the countersunk bolt matched with the thread through hole is arranged in the thread bolt. The reusable machine reamer has the advantages that the machine reamer is reusable, service life of the machine reamer is tens of times service life of existing machine reamers, reaming production costs are greatly saved, and economic benefits are obvious.
Description
Technical field
The utility model relates to a kind of reusable chucking reamer, belongs to machining tool technical field.
Background technology
In machinery fraising process, only used the chucking reamer of 1～2 time, will not require to scrap because its dimension limit reaches fraising, so in a large amount of machinery fraising production processes, will constantly change chucking reamer, cause fraising production cost significantly to improve, meanwhile, this is also a kind of very large waste.
Summary of the invention
The purpose of this utility model is just to provide a kind of reusable chucking reamer, for addressing the above problem.
The technical solution of the utility model is: a kind of reusable chucking reamer, comprise reamer cutting portion, copper sheet, countersunk head double-screw bolt, reamer neck and reamer taper shank, reamer cutting portion, reamer neck and reamer taper shank are cast as one, described reamer cutting portion and reamer neck are divided equally and are cut to neck stage casing along its axial line, described reamer cutting portion is being provided with copper sheet by the incision linear slit of blade, described copper sheet thickness is 0.03-0.6 ㎜, on described reamer neck with cut-off lines vertical direction on be provided with a tapped through hole, described tapped through hole is provided with the countersunk head double-screw bolt matching with it.
The beneficial effects of the utility model are: reusable, be the decades of times of existing chucking reamer its service life, greatly save fraising production cost, and economic benefit is obvious.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, known with reference to accompanying drawing 1, a kind of reusable chucking reamer, comprise reamer cutting portion 1, copper sheet 2, countersunk head double-screw bolt 3, reamer neck 4 and reamer taper shank 5, reamer cutting portion 1, reamer neck 4 and reamer taper shank 5 are cast as one, described reamer cutting portion 1 and reamer neck 4 are divided equally and are cut to neck stage casing along its axial line, described reamer cutting portion 1 is being provided with copper sheet 2 by the incision linear slit of blade, described copper sheet 2 thickness are 0.03-0.6 ㎜, on described reamer neck 4 with cut-off lines vertical direction on be provided with a tapped through hole, described tapped through hole is provided with the countersunk head double-screw bolt 3 matching with it.During fraising, when reamer cutting edge blunt time, unclamp countersunk head double-screw bolt 3, according to the degree of wear of reamer cutting edge, by in the incision linear slit of blade beyond the Great Wall thickness be the copper sheet 2 of 0.03-0.6 ㎜, then tighten countersunk head double-screw bolt 3, on cutter and tool grinding machine, carry out again sharpening, thereby the original size when obtaining this reamer and using for the first time, the fraising diameter dimension of this reamer has just been adjusted like this, can ream for the second time, later whenever reamer cutting edge blunt time, all carry out as stated above the adjustment of reamer diameter size, the thickness difference of the copper sheet 2 of pad while only at every turn adjusting, adjusting range is in 0-0.6 ㎜ left and right, such once reamer being reused tens of times more than, reach the object that greatly reduces fraising production cost.
