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 and 2, an internal diameter instrument calibrating device comprises a base 1, a micrometer screw 2, a support base 3, a swing rod 4, a spring 5, a guide post 6, a contact head 7 and a standard sleeve 8, wherein the support base is arranged on the upper portion of the base, the micrometer screw is mounted on one side of the support base, a measuring head of the micrometer screw extends out of the bottom of the support base to be in contact fit with one end of the swing rod, the middle portion of the swing rod is hinged to the support base, namely, distances between two sides of the swing rod are the same, the purpose is to make the micrometer screw and the internal diameter instrument symmetrical, the support base is fixed at the bottom of the support base, one end of the guide post is fixedly connected with the bottom of the support base, the other end of the guide post passes through a guide groove on the swing rod and then is limited and fixed through a bolt, the spring is sleeved on the guide post, and two ends of the bolt are, the upper portion of the other end of the swing rod is provided with a protrusion 9, the protrusion corresponds to a threaded hole formed in the supporting platform, an inside diameter instrument 10 to be measured is connected to the threaded hole in a threaded mode, the contact head is fixed to the position below the right side of the swing rod, and the contact head is matched with the inner wall of a standard sleeve fixed to the bottom of the base.
In order to facilitate carrying of the device, the support platform is provided with a handrail 11.
In order to position the standard sleeve, two positioning columns 12 are arranged on two sides of the bottom of the base, and the positioning columns are in insertion fit with positioning holes in the top of the standard sleeve.
The working principle is as follows: the device adopts a standard sleeve 8, so that the standard sleeve is detachably fixed at the bottom of a base, before measurement is started, the standard sleeve is fixed at the bottom of the base, the reading of a micrometer screw is zero, at the moment, a swinging rod is positioned at the horizontal positions at two sides, namely, a measuring head of the micrometer screw is contacted with the top of the swinging rod, meanwhile, a contact head is also contacted with the inner wall of the standard sleeve, after all adjustment is finished, the diameter gauge can be verified, the diameter gauge is screwed into a threaded hole on a supporting table, the reading can be generated when the measuring head is contacted with the top of the swinging rod, at the moment, the diameter gauge cannot be continuously screwed, after positive and negative adjustment, the reading of the diameter gauge is also zero, at last, the standard sleeve is taken down, the micrometer screw is rotated, the reading of the diameter gauge is observed, under normal conditions, due to the lever principle, the readings of the two are the same, and if the diameter gauge has, the readings may not be synchronous and the bore gauge may need to be adjusted.
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.
