Description
Technical field
The present invention relates to drilling tool technical field, particularly relate to a kind of deep hole R groove end surface measurement 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, gear wheel hole and bit leg axle respectively have a semicircular groove of annular, the degree of accuracy of the axial location of its door 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 there is the bearing pin meeting performance requirement to collecting together momentum.The sealing effectiveness of bearing plays conclusive effect the service time to bearing.The measurement instrument of current routine, accurately can not measure the relative position between gear wheel hole internal diameter groove and gear wheel hole bottom end face, if the spacing of internal diameter groove and end face is against regulation will cause bearing Fast Wearing, tooth-wheel bit is scrapped.Thus, in industry, 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 a kind of deep hole R groove end surface measurement measurer is provided, can the distance between gear wheel deep hole R groove and end face 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 R groove end surface measurement measurer, comprise main body, dial gauge, operating parts, thimble and slide block, described dial gauge is arranged on gauge stand, described main body is provided with left and right two cavitys, is provided with push rod in described left cavity, and on described push rod, cover has the first spring, described gauge stand is arranged on the top of described left cavity, and the sounding rod of described dial gauge coordinates with described push rod; Described thimble is provided with in described right cavity, coordinate with described slide block bottom described thimble, on described thimble, cover has the second spring, described thimble top coordinates with rotating shaft, and described rotating shaft is threaded with described operating parts, and the top of described operating parts and described right cavity is slidably matched, the sidewall of right cavity is provided with dog screw, described dog screw coordinates with described operating parts, and the top of described thimble coordinates with bottom described rotating shaft, and the top of described rotating shaft is fixed with nut.The present invention is simple and practical, slide block in right cavity first carries out positioning gear wheel endoporus, after Internal hole positioning, on dial gauge, show numerical value by push rod and can judge that whether the distance between groove to end face is qualified, rapid and convenient, first this device is corrected before use, by this device to one more regular measure after, 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.
Preferably, described slide block is at least three pieces, is distributed in the ring week of described thimble, is linked together by elastic spring.The ring week of gear wheel endoporus can be withstood on so uniformly, improve measurement precision.
Preferably, described dial gauge is fixed by locking member and described gauge stand.Quick-replaceable can be carried out to dial gauge by locking member.
Preferably, described gauge stand is provided with handle.
The invention has the beneficial effects as follows: the present invention is simple and practical, slide block in right cavity first carries out positioning gear wheel endoporus, after Internal hole positioning, on dial gauge, show numerical value by push rod and can judge that whether the distance between groove to end face is qualified, rapid and convenient, first this device is corrected before use, by this device to one more regular measure after, 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.
