Abstract
The invention relates to a calibration measuring rod sleeve for an outside micrometer. A sleeve body, a spring, a locating ring, a locking ring and a nut are sequentially installed on a calibration measuring rod. When the calibration measuring rod sleeve is in use, the sleeve body is pulled back to be aligned with a measuring anvil or a micrometric screw of the outside micrometer and then is loosened, and the head portion of the calibration measuring rod and the measuring anvil or the micrometric screw are connected in a butt joint mode and fixed together through the sleeve body. In the process of calibrating the outside micrometer, it is not needed to hold the calibration measuring rod to carry out calibration.
Description
Technical field
The present invention relates to a kind of aid of measurer.
Background technology
Before use outside micrometer is measured, calibrator quantity pole pair outside micrometer is used to calibrate, calibration gauge rod is needed to be placed between the gage button of outside micrometer and micrometering screw rod, general outside micrometer can attach a plastic jacket, be used for temporarily docking calibration gauge rod and gage button (as Fig. 1), but this plastic jacket is easy to lose, and easily comes off in use, calibration gauge rod is caused to drop damage.Therefore need during operation, hand steered a gage button one end, another hand completes calibration operation.If large-scale outside micrometer, need two people to operate, people hand steered gage button one end, another person completes calibration operation, check and correction is operated very inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of measurer aid, can be arranged on calibration gauge rod, is fixed on outside micrometer by calibration gauge rod during convenient calibration outside micrometer.
The technical scheme that the present invention solves this technical problem employing is: a kind of outside micrometer calibration gauge rod cover, comprises sleeve, spring, locating ring, retaining ring and nut.Locating ring is processed with external thread, open slot, retaining ring is processed with female cone threaded hole, the female cone threaded hole screwing into retaining ring of locating ring, makes locating ring tighten gradually, locating ring is fixed on the bar head of calibration gauge rod by retaining ring, is used for fixing position of the present invention; Sleeve is contained on the bar head of calibration gauge rod, and mounting spring between locating ring, and sleeve can slide along bar head, is used for docking to calibrate gauge rod and gage button or micrometric screw; Spring controls the flexible of sleeve; Spring, locating ring, retaining ring are enclosed in sleeve by nut.
Sleeve stretches out by the elastic force effect of spring in a relaxed state and the bar head of calibration gauge rod is wrapped in the inside, during use, sleeve is retracted, expose the bar head of calibration gauge rod, and aim at gage button or the micrometric screw of outside micrometer, then unclamp sleeve, sleeve stretches out under the elastic force effect of spring, the calibration bar head of gauge rod and gage button or micrometric screw is together encased, be docking together, can by outside micrometer and stable being secured together of calibration gauge rod.
Locating ring is processed with open slot, makes open slot place produce distortion when retaining ring screws in, what locating ring was fixed on calibration gauge rod is more firm.The oral area of sleeve is taper hole, for the guiding of gage button or micrometric screw, is convenient in access aperture.
After being fixed on outside micrometer by the present invention by calibration gauge rod, operator a people can complete calibration, does not need to hold up calibration gauge rod again.Calibrate gauge rod without time, the bar head of calibration gauge rod is wrapped in the inside by sleeve, plays the effect of protection to the bar head of calibration gauge rod.
Accompanying drawing explanation
Fig. 1 is original outside diameter milscale calibration schematic diagram.
Fig. 2 uses schematic diagram of the present invention.
Fig. 3 is cut-open view under sleeve relaxation state of the present invention.
Fig. 4 is that sleeve of the present invention retracts cut-open view under state.
Fig. 5 is that the present invention breaks up figure.
In Fig. 1 ~ 5: 1. gage button, 2. sleeve, 3. spring, 4. locating ring, 5. retaining ring, 6. nut, 7. calibration gauge rod, 8. micrometric screw, 9. outside micrometer.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Fig. 2 ~ 5, nut (6), retaining ring (5), locating ring (4), spring (3), sleeve (2) are installed in calibration gauge rod (7) successively, locating ring (4) is placed into correct position, set nut (5) is screwed in, because its endoporus is tapered tread, locating ring (4) is locked on calibration gauge rod.Spring (3) is put in the endoporus of sleeve (2), is pressed onto on locating ring (4), is screwed in nut (6) by sleeve (2), completes installation.
During calibration outside micrometer, pull sleeve (2) inwards, expose the bar head of calibration gauge rod (7), aim at the gage button (1) of outside micrometer, unclamp rear sleeve (2) to pop into position by the elastic force of spring (3), be docking together by the bar head of gage button (1) with calibration gauge rod (7), now sleeve (2) can not be retracted by spring (3) elastic force, and operator can arrive another side operation.
Also be provided with the present invention at the other end of calibration gauge rod (7), method of operating is identical, together with the bar head calibrating gauge rod (7) is docked to micrometric screw (8) by sleeve (2).To calibrate after gauge rod (7) and outside micrometer (9) be fixed together, operator can start to calibrate outside micrometer (9), does not need hand steered calibration gauge rod (7) again.
Under sleeve relaxation state, the bar head calibrating gauge rod (7) is wrapped in the inside by sleeve (2), can play the effect of guard bar head.
Claims (2)
1. an outside micrometer calibration gauge rod cover, main body is sleeve, locating ring and retaining ring, it is characterized in that: on calibration gauge rod, sleeve, spring, locating ring, retaining ring and nut are installed successively, locating ring there are external thread, open slot, retaining ring there is female cone threaded hole, locating ring screws in retaining ring female cone threaded hole, is provided with spring, locating ring and retaining ring, is enclosed in sleeve by nut in sleeve.
2. outside micrometer calibration gauge rod cover according to claim 1, is characterized in that: the oral area of sleeve is taper hole.
