Abstract
The utility model relates to a kind of outside micrometer calibration gauge rod cover, its main body is cylindrical sleeve, bushing core is step through-hole, one lateral opening be gage button mounting hole, another is lateral opening is calibration gauge rod mounting hole, two lateral opening be enclosed within outside micrometer respectively gage button (or micrometric screw) and calibration gauge rod bar head on, calibration gauge rod and outside micrometer are fixed together, operator does not need hand steered calibration gauge rod when calibrating outside micrometer, make calibration operation convenient, it also avoid the impact of staff temperature on measurer precision.
Description
Technical field
The utility model 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 the outside micrometer of large gauge, need two people to operate, people hand steered gage button one end, another person completes calibration operation, check and correction is operated very inconvenient.Hand steered calibration gauge rod, the temperature of human body can have an impact to measurer precision.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of measurer aid, is docked on outside micrometer by calibration gauge rod during convenient calibration outside micrometer.
The technical scheme that the utility model solves this technical problem employing is: a kind of outside micrometer calibration gauge rod cover, main body is a cylindrical sleeve, there is step through-hole centre, and be gage button mounting hole, its diameter is larger than gage button diameter, oral area is taper hole, another side is calibration gauge rod mounting hole, and its diameter is larger than calibrator quantity shank diameter, and sleeve is used for docking gage button and calibration gauge rod, in calibration gauge rod mounting hole, there is annular groove, and O-ring seals is installed.
The calibration gauge rod mounting hole of sleeve is enclosed within the bar head of calibration gauge rod, and gage button mounting hole is enclosed within gage button, the gage button of outside micrometer and calibrator quantity pole pair can be connect, and the micrometric screw of outside micrometer and calibrator quantity pole pair can be connect equally.After outside micrometer and one end of calibration gauge rod are secured together, operator can carry out calibration operation.
Have annular groove, the in-built O RunddichtringO of groove in calibration gauge rod mounting hole, internal diameter is less than the diameter of calibration gauge rod, can surround bar head after being inserted in the bar head of calibration gauge rod, and what sleeve was fixed on calibration gauge rod is more firm, can not in use landing.The oral area of gage button mounting hole is taper hole, leads, be convenient in gage button access aperture during suit for gage button.
After being fixed on outside micrometer by the utility model by calibration gauge rod, operator a people can complete calibration, does not need to hold up calibration gauge rod again, makes calibration operation convenient, the temperature of staff can be avoided the impact of measurer precision.

Fig. 4 is the utility model cut-open view.
In Fig. 1 ~ 4: 1. outside micrometer, 2. gage button, 3. calibration gauge rod, 4. micrometric screw, 5. sleeve, 6. O RunddichtringO, 7. gage button mounting hole, 8. calibration gauge rod mounting hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 2 ~ 4, when using calibration gauge rod (3) calibration outside micrometer (1), first the calibration gauge rod mounting hole (8) of sleeve (5) is enclosed within the bar head of calibration gauge rod (3).Again gage button mounting hole (7) is enclosed within gage button (2), the oral area of gage button mounting hole (7) is taper hole, lead when being set with for gage button (2), be convenient in access aperture, the gage button of outside micrometer (1) (2) can be docked with calibration gauge rod (3), after outside micrometer (1) and one end of calibration gauge rod (3) are secured together, operator can carry out calibration operation.O RunddichtringO (6) in calibration gauge rod mounting hole (8) can surround the bar head of calibration gauge rod (3), makes sleeve can not landing in check and correction process.
For the outside micrometer of small dimension, check and correction operation can be carried out after only gage button (2) need being docked, dock if the outside micrometer of large gauge can use the utility model will calibrate gauge rod (3) with micrometric screw (4), as shown in Figure 2, calibration gauge rod (3) and outside micrometer (1) stable being fixed together is made.
After being fixed on outside micrometer by the utility model by calibration gauge rod, operator a people can complete calibration, does not need to hold up calibration gauge rod again, makes calibration operation convenient, the temperature of staff can be avoided the impact of measurer precision.
Claims (2)
1. an outside micrometer calibration gauge rod cover, main body is sleeve (5), it is characterized in that: cylindrical sleeve (5), center is step through-hole, one lateral opening be gage button mounting hole (7), aperture is greater than gage button diameter, another lateral opening for calibration gauge rod mounting hole (8), aperture is greater than calibrator quantity shank diameter, has annular groove in calibration gauge rod mounting hole (8).
2. the outside micrometer calibration gauge rod cover according to claim 1, is characterized in that: mounting O-shaped O-ring seal (6) in annular groove, gage button mounting hole (7) oral area is bellmouth.
