Description
Technical Field
The utility model relates to an instrument and equipment detects technical field, especially relates to a ring gauge calibrating installation.
Background
The ring gauge is also called a correction ring gauge, and is a circular ring with specific size and attribute for correcting the defects of a measuring tool. At present, the ring gauge is generally calibrated by adopting an inner diameter instrument, the width of the inner diameter of some large ring gauges is wide, the ring gauge cannot be used for measurement, and even if the ring gauge can be used for measurement, the numerical value is not accurate enough.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of above-mentioned technique, and provide a ring gauge calibrating installation.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: the utility model provides a ring gauge calibrating installation which characterized in that: comprises a base, a pneumatic three-jaw chuck, an L-shaped fixing plate, a connecting plate and a lever type dial indicator; the L-shaped fixing plate is fixed on the base, the pneumatic three-jaw chuck is fixed on one side of the L-shaped fixing plate, measuring jaws are respectively fixed at three moving ends of the pneumatic three-jaw chuck, the cross section of each measuring jaw is L-shaped, the cross section of each measuring jaw is circular after being closed, the measuring jaws moving horizontally in the pneumatic three-jaw chuck are in threaded connection with measuring rods of the lever-type dial indicator, and the lever-type dial indicator is fixed on the side portion of the L-shaped fixing plate through the connecting plate.
Preferably, the bottom of the base is provided with four legs.
Preferably, a connecting block is integrally formed at the lower part of the horizontally moving measuring jaw in the pneumatic three-jaw chuck and is connected with the measuring rod through a nut.
The utility model has the advantages that the device combines the dial indicator and the pneumatic three-jaw chuck in the prior art, can be suitable for a large-size ring gauge, has very high verification speed, is suitable for large-batch verification in a laboratory, and improves the verification efficiency.

Detailed Description
Spatially relative terms such as "above … …", "above … …", "above … …", "above", and the like, may be used herein for ease of description to describe the spatial relationship of one feature or characteristic to another feature or characteristic as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
As shown in fig. 1, the ring gauge calibrating device comprises a base 1, a pneumatic three-jaw chuck 2, an L-shaped fixing plate 3, a connecting plate 4 and a lever type dial indicator 5; the L-shaped fixing plate is fixed on the base, the pneumatic three-jaw chuck is fixed on one side of the L-shaped fixing plate, three moving ends of the pneumatic three-jaw chuck are respectively fixed with a measuring jaw, the cross section of the measuring jaw is L-shaped, the cross section of the measuring jaw is circular after being closed, the pneumatic three-jaw chuck is a purchased finished product, and can be selected from four jaws. The lever type dial indicator is fixed on the side part of the L-shaped fixing plate through the connecting plate. The lever type dial indicator is also an outsourcing product and can display measured numerical values.
To facilitate the use of the device, the base is provided with four legs 9 at its bottom.
During the use, the middle is regained to pneumatic three claw chuck's three claw, and the lever percentage table is the state of zero, puts into the ring gauge on measuring the claw, starts three claw chuck, contacts ring gauge inner wall after three measuring the claw, reads the reading of lever percentage table, can judge whether qualified ring gauge is, and this device combines percentage table and pneumatic three claw chuck among the prior art, can be applicable to bulky ring gauge, and examination speed is very fast, is applicable to the big batch examination in laboratory, has improved examination efficiency.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
