Embodiment
Gear depth gauge such as Fig. 1 in the oil country tubular goods taper thread of the present utility model-shown in Figure 4, it comprises the stainless steel body 1 of a hollow, be provided with a lever 2 in the body 1, this lever 2 is the fine motion lever, realize along register pin 4 swings by lining 3 and register pin 4 that middle part in managing arranges, body 1 one ends are provided with chaining pin mechanism 5, body 1 other end is provided with indicating gauge 6, this indicating gauge 6 can be selected instrument such as corresponding dial gauge according to the measurement demand, the lower end of chaining pin mechanism 5 contacts with lever 2 two ends upper surfaces respectively with the motion bar 7 of indicating gauge 6 lower ends, also be provided with finger plate mechanism on the body 1, described finger plate mechanism comprises shaft seat 8, stage clip 9, but the finger plate 10 of horizontal hunting and lower platen 11, shaft seat 8 is fixedly arranged on the body 1, finger plate 10 1 ends are provided with compression leg 12 and place chaining pin mechanism 5 tops, finger plate 10 other ends are located at shaft seat 8 upper ends by screw 13a, lower platen 11 1 ends are provided with platen 19, the other end of lower platen 11 is connected on the shaft seat 8 by screw 13b and stage clip 9, and is connected with finger plate 10 by Change-over frame 14.So, when unclamping screw 13a, can realize finger plate 10 about 30 degree swings, calibrate thereby the tooth depth calibrated bolck conveniently is set.After tightening screw 13a, by pressing down platen 19, and the transmission by parts such as lower platen 11, Change-over frames 14, thereby can drive upwarping, unclamping of finger plate 10, in order to screw thread to be measured is measured.
And described chaining pin mechanism 5 comprises chaining pin seat 15, chaining pin spring 16 and chaining pin 17, chaining pin seat 15 is fixed on body 1 one end upper surfaces, chaining pin 17 is located in the chaining pin seat 15, and the lower end is stretched in the body 1, and chaining pin spring 16 is sheathed on the chaining pin 17 and offsets with the pin cap 18 of chaining pin 17.Described body 1 other end upper surface also is installed with for the gauge stand 20 that indicating gauge 6 is installed, and the motion bar 7 of indicating gauge 6 passes gauge stand 20 and stretches in the body 1.After the motion bar 7 of lever 2 right-hand member indicating gauges 6 compresses, lift on the left end of lever 2, make pin cap 18 compression chaining pin springs 16, make chaining pin 17 rise or descending motion inside.In like manner, when chaining pin 17 liftings, the motion bar 7 that drives indicating gauge 6 by lever 2 meetings is flexible, thereby the pointer that drives indicating gauge 6 changes, with the reflected measurement result, and direct reading.
Described body 1 two ends are uncovered, and an end end that is provided with chaining pin mechanism 5 seals by plug 21 is set, and an end end that is provided with indicating gauge 6 is connected with handle 22.Handled easily so not only, and by to the sealing in managing, can prevent that foreign material from entering is with the accuracy that guarantees measuring mechanism and the degree of accuracy of measurement.
The principle of work of gear depth gauge is as follows in the oil country tubular goods taper thread of the present utility model:
At first, need to come this measuring instrument is calibrated by the tooth depth calibrated bolck.Before the calibration, unclamp screw 13a earlier, level is rotated finger plate 10 to the left or to the right to hands-off position, the U-shaped of tooth depth calibrated bolck or V-type groove are placed on the chaining pin 17, make it be in the peak of groove just, compress the reference field of calibrated bolck then to chaining pin seat 15, swing a little, and the pointer of indicating gauge 6 is transferred to zero-bit.
Then, finger plate 10 is rotated back into the origin-location, and tighten screw 13a, with the handle 22 of holding with a firm grip on the other hand, thumb presses down platen 19, and lower platen 11 can be lifted under the effect of stage clip 9, drives finger plate 10 perks by Change-over frame 14 and opens certain angle.
At last, chaining pin 17 is inserted the bottom of tested oil country tubular goods taper thread internal tooth, unclamp the thumb that is pressed on the platen 19, the compression leg 12 of finger plate 10 ends is close on the tested internal taper threaded line pipe outer wall, there are differences between U-shaped (or V-type) groove depth because of tooth depth and tooth depth calibrated bolck in the tested oil country tubular goods taper thread, can cause that chaining pin 17 moves up and down, and then drive lever 2 revolutions, the motion bar 7 of the indicating gauge 6 that is pressed in lever 2 opposite sides is moved, as long as read the variation lattice number of pointer on the indicating gauge 6, just can judge that whether qualified tested oil country tubular goods taper thread internal tooth high measurement deviate is thus, thereby realize accurately measuring.
But, those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
