Cutting tooth on first 10 works normally, and when borehole diameter is up to standard, wear-resistant ball 15, gauge teeth 5, wear-resisting arcs 3 do not work；Work as drill bit
When cutting tooth on 10 is gradually worn out so that the diminution of institute's bored borehole cannot be up to standard, it is mounted between spiral matrix 8 and matrix support 9
Wear-resistant ball 15 grinding reduce the borehole wall start its gauge work, gauge teeth 5, wear-resisting arcs 3 do not work at this time, and wear-resistant ball 15 exists
It is rolled in ball 802 while being ground the borehole wall, can reduce the friction between wear-resistant ball 15 and the borehole wall using rolling action, increased
The service life of wear-resistant ball 15 enhances gauge effect, and wear-resistant ball 15 is mounted on spiral helicine spiral matrix 8, does not influence drill bit
10 chip removal；When with wear-resistant ball 15, constantly abrasion causes borehole diameter not up to standard, gauge teeth 5 starts to carry out the borehole wall of diminution
Cutting, wear-resisting arcs 3 do not work at this time；When gauge teeth 5, which is gradually worn, causes borehole diameter not up to standard, wear-resisting arcs 3 are ground
The borehole wall for cutting diminution starts gauge work, is removed after wear-resisting 3 serious wear of arcs.When 10 frequent progress of drill bit pulls out of hole
When the operations such as reaming, it is easy to appear gauge abrasion and the outer cutting tooth on drill bit 10 the case where capable of working normally, only needs at this time
It removes spiral matrix 8 and replaces the gauge ring 4 of wear-resistant ball 15 and replacement equipped with gauge teeth 5 without more bit change, make in reduction
Drilling efficiency is improved while with cost.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
