Description
Technical field
The present invention relates to a kind of depth detection apparatus, relate in particular to a kind of degree of depth that engine or wheel box oil sealing be pressed into and pick-up unit of unevenness of being used for.
Background technology
At present, in engine and wheel box assembling field, the degree of depth that is pressed into for its oil sealing and the detection of unevenness generally adopt two kinds of modes to detect.A kind of mode is to adopt pit gauge, and it will select three points to measure in a circumference in measuring process at least, and the overlong time of operation and inconvenience cause the numerical error rate measured too high, and numerical value is also not accurate enough reliable; Another mode is to adopt height gauge, and is though its numerical error of measuring can be a little bit smaller, inconvenient equally in the time of operation.More than the mode of two kinds of measurements, when measuring, also be difficult to find accurately the reference field of the article of surveying.China Patent No. 01239740.7 discloses a kind of O RunddichtringO cavity depth measuring instrument, it comprises the measuring head on the dial gauge, threaded engagement between the three joint cavity connecting links, first segment cavity connecting link docks with measuring head on the clock gauge by its center pit, in the second joint cavity connecting link adjusting screw plug is arranged, chaining pin stretches out in the 3rd joint cavity connecting link and spring pressure adjusting screw plug back warp end aperture, stage clip is regulated between the screw plug at chaining pin and spring pressure, regulate screw plug and be coniform, have expansion slot on the wall, it is characterized in that the terminal end shape of the 3rd joint cavity connecting link is semicircle R face.
Therefore, be necessary to provide a kind of convenient and practical depth detection apparatus, so that overcome the shortcoming and deficiency of prior art.
Summary of the invention
The purpose of this invention is to provide a kind of depth detection apparatus, it not only easily finds the reference field of the article of surveying accurately, and, by the precision of parts clock gauge self wherein, make the numerical value measured more accurately and reliably, do not need to remove to calculate numerical value again, easy to operate.
To achieve these goals, the technical solution adopted for the present invention to solve the technical problems is: a kind of depth detection apparatus, comprise clock gauge or dial gauge, this depth detection apparatus also comprises a sleeve, center pit and diameter upper end hole and the following stomidium greater than center pit arranged in the sleeve, sleeve one end connects a hollow top cover, in the hollow top cover by the fixing clock gauge of set screw, gauge head roof pressure one sounding rod of clock gauge; Sounding rod is free to slide at the sleeve center pit, is with a spring on the sounding rod; One end of spring and hollow top cover bottom be roof pressure mutually, the other end be fixed on sounding rod on link stopper roof pressure mutually; The lower end of sounding rod connects a survey dish; Under non-measurement state, survey dish end face stretches out sleeve lower end hole end surface.
In order to protect and the reliable clock gauge of installing, clock gauge inserts hollow top cover appearance partly and is with an elastic jacket.Clock gauge can also be the digital display type clock gauge.
Preferred as such scheme, described link stopper is the ring washer that is actively connected on the sounding rod.
Its principle of work is exactly to utilize the flexible promotion of sounding rod upper spring to make moving up and down of dial gauge gauge head, its medi-spring is in compressive state when not measuring, the survey dish is the measuring basis bottom surface that exceeds sleeve, when measuring like this survey dish when touching workpiece can on move, simultaneously sounding rod will on move, the gauge head of promotion table moves on also, and table will show corresponding numerical value.
Good effect of the present invention is owing to only adopt a sleeve, and with a sleeve bottom faces as the measuring basis face, adopt the directly clock gauge of demonstration reading simultaneously.Therefore, this depth detection apparatus is simple in structure, and it is cheap to manufacture this installation cost, the cost of economizing on the use of funds.In the process of operation, pick-up unit need only be put into the workpiece of being surveyed, just can draw accurate values, simple and practical, need repeated measurement in order to obtain accurate values, saved the time, improved work efficiency.In addition, this device versatility is good, can carry out depth detection to different types of workpiece, and the error of workpiece processing is very little to its influence.
Description of drawings
Fig. 1 is the organigram of analysing and observe of depth detection apparatus of the present invention.
Fig. 2 is the enlarged diagram of B part among Fig. 1.
Embodiment
As shown in Figure 1, the structure of this depth detection apparatus comprises clock gauge 1, sleeve 8; Be provided with center pit in the sleeve 8, its diameter is greater than the upper end hole 7 and the following stomidium 12 of center pit; One end of sleeve 8 connects hollow top cover 5, and by the fixing clock gauge 1 of set screw 3, wherein, the appearance of clock gauge 1 insertion hollow top cover 5 parts is with elastic jacket 2 in the hollow top cover 5, makes being fixed in the hollow top cover 5 that it can be more firm; Gauge head 4 roof pressures one sounding rod 11 of clock gauge 1, sounding rod 11 is free to slide in sleeve 8 center pits; Be with spring 6 on the sounding rod 11, an end of spring 6 and hollow top cover 5 bottoms are roof pressure mutually, the other end be fixed on sounding rod 11 on link stopper 9 roof pressure mutually; Wherein, link stopper 9 can be a ring washer that is movably connected on the sounding rod 11, keeps spring 6 to be in compressive state; The lower end of sounding rod 11 connects a survey dish 14, and under non-measurement state, survey is coiled 14 end faces and stretched out 8 times stomidium 12 end faces of sleeve.
Clock gauge 1 can be dial gauge, more can be digital display meter, makes the numerical value quicklook more of measuring.
Its course of work is exactly to carry out dial gauge with correcting block earlier to proofread and correct zero clearing, and just bottom surface and the survey face of trying to get to the heart of a matter with sleeve is placed on the correcting block, and they are on the plane.Then the measuring basis bottom surface of sleeve is placed on the basal plane that workpiece need measure, the survey dish is because the tension force of spring can touch the oil sealing outer face, basal plane is exactly frock overcoat bottom surface and the difference in height of surveying the face of trying to get to the heart of a matter to the difference in height of the outer face of oil sealing like this, and just table is gone up the value that shows.Its operation is very simple, and is fast and directly perceived.
As shown in Figures 1 and 2, in use, earlier the bottom surface of sleeve 8 and the bottom surface of survey dish 14 are positioned on the correcting block 16, it is on the surface level, dial gauge is carried out school zero (the direct zero clearing of digital display meter).Then this depth detection apparatus is put into oil sealing 15 outer faces of the workpiece of surveying 13, survey dish 14 is because the tension force of spring 6 touches the outer face of the oil sealing of surveying 15, drive gauge head 4 displacements of sounding rod 11 and institute's roof pressure thereof simultaneously, the shown numerical value that comes out of final clock gauge 1 is exactly the degree of depth that oil sealing 15 is pressed into, in other words, its degree of depth is exactly 14 bottom surfaces are coiled in sleeve 8 measuring basis bottom surfaces to survey a difference in height.
