Description
Technical field
The present invention relates to drilling tool technical field, particularly relate to a kind of deep hole internal diameter R groove and measure measurer.
Background technology
The tooth-wheel bit great majority used in oil, gas drilled hole and other mining drill spies are seal form.Sealed roller cone drill bit is formed primarily of bit leg, bit leg axle, gear wheel, gear wheel hole, locking element and seal.The key factor affecting the serviceable life of tooth-wheel bit in oil, gas drilled hole is life-span of bearing arrangement and bearing life and sealing life.By dissect and analyze tooth-wheel bit failure mode we find that sealing life is again the most direct restraining factors in its tooth-wheel bit life-span.Along with the development of tooth-wheel bit technology has produced dual seal tooth-wheel bit, the ability that this kind of drill bit adapts to high rotating speed high temperature is strong.Dual seal tooth-wheel bit has two seals circle than list sealing tooth-wheel bit in the past, and outer O-ring seal is sand retaining ring, and inner O-ring seal is primary seal circle, sand retaining ring protection primary seal circle, primary seal circle protection bearing.Dual seal tooth-wheel bit improves the serviceable life of tooth-wheel bit.Along with dual seal tooth-wheel bit use we find to improve the key that life-span of sand retaining ring is again dual seal drill bit.Because it is faster that the faster mud that sand retaining ring damages and landwaste contact primary seal, primary seal circle is shorter for service time, and final bit life is shorter.For tooth-wheel bit, the quality of its bearing seal and lubrication directly affects the life-span of tooth-wheel bit.
The tooth-wheel bit that petroleum drilling and other mining drill spy aspect use, as gear wheel and the bit leg axle lock shaft steel ball to position location, the runway of its similar common rolling bearing of runway, be commonly referred to as R groove, the degree of accuracy of its axial location is an important parameter of cone bit bearing part, its levels of precision, be directly connected to the sealing effectiveness of cone bit bearing, should be the axial location apart from thrust surface strictly speaking, which determine thrust surface whether can be adjacent to, and have the bearing pin meeting performance requirement to collecting together momentum.The sealing effectiveness of bearing plays conclusive effect the service time to bearing.Sealing effectiveness is not good or lost efficacy, and the impurity such as Transport of Drilling Cutting In A immerse bearing bore, and bearing very quick-wearing, tooth-wheel bit is scrapped, and even occurs down-hole accident.The measurement instrument of current routine, accurately can not measure the axial location of palm axis R groove, in industry, and need with a kind of measurement instrument solving this problem.
Summary of the invention
The object of the invention is to the deficiency overcoming above-mentioned technology, and provide a kind of deep hole internal diameter R groove to measure measurer, pinch roller groove can be tested, improve the qualification rate of product.
The present invention for achieving the above object, by the following technical solutions: a kind of deep hole internal diameter R groove measures measurer, comprise dial gauge, operating parts, slide block, connector and Connection Block, described dial gauge is fixed on gauge stand, described gauge stand is fixed on described operating parts, the sounding rod of described dial gauge is deep into described gauge stand inside, the sounding rod of described dial gauge coordinates with the micrometer adjusting screw of described operating parts inside, described micrometer adjusting screw has been threaded trimming hand wheel, described operating parts is inserted in described connector and is fixed by dog screw with it, described connector has reseted cone, in described cone, cover has spring, described Connection Block is provided with bottom described connector, described slide block is provided with in described Connection Block, described slide block and described taper fit.The present invention is simple and practical, can be tested to the internal channel in gear wheel hole by the present invention, slide block is around thimble, it is all wedge shape, the stroke of slide block passes to cone, cone passes to dial gauge by micrometer adjusting screw again, whether can judge that whether product is qualified, rapid and convenient in the error range allowed by observing numerical value.First this device is corrected before use, after this device being measured by each a product, correct the numerical value of dial gauge, zero degree can be transferred to, re-use this device when other workpiece are measured, only need to judge measuring workpieces whether about zero degree, simple and practical.Operating parts first carries out coarse adjustment, can finely tune by measuring handwheel to this device.
Preferably, described slide block is at least three pieces, is distributed in the ring week of described thimble, is linked together by extension spring.The ring week of gear wheel endoporus can be withstood on so uniformly, improve measurement precision.
Preferably, affixed by locking member between described dial gauge and gauge stand.
Preferably, described gauge stand is provided with handle.
The invention has the beneficial effects as follows: the present invention is simple and practical, can be tested to the internal channel in gear wheel hole by the present invention, slide block is around thimble, it is all wedge shape, the stroke of slide block passes to cone, cone passes to dial gauge by micrometer adjusting screw again, whether can judge that whether product is qualified, rapid and convenient in the error range allowed by observing numerical value.First this device is corrected before use, after this device being measured by each a product, correct the numerical value of dial gauge, zero degree can be transferred to, re-use this device when other workpiece are measured, only need to judge measuring workpieces whether about zero degree, simple and practical.Operating parts first carries out coarse adjustment, can finely tune by measuring handwheel to this device.
