Description
Technical Field
The utility model relates to an instrument and equipment detects technical field, especially relates to a smooth limit tester calibrating installation.
Background
The smooth limit tester (measuring gauge) is a special structure which is arranged according to different shapes of products, when in measurement, a gauge and a workpiece measuring cylindrical surface are cleaned, and the gauge and the workpiece measuring cylindrical surface are inserted slightly after being oiled, so that the workpiece can not be forced to observe whether the workpiece is qualified, so the gauge must be verified at intervals, and the current verification mode can only verify whether the peripheral surface of the measuring gauge is deformed, but can not know whether the top of the gauge is flush.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of above-mentioned technique, and provide a smooth limit tester calibrating installation.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: the utility model provides a smooth limit tester calibrating installation which characterized in that: the device comprises a digital dial indicator, a connecting plate, a rotating shaft, a supporting column, a bottom plate, a cushion block and a clamping block; the support column is fixed in the middle of the bottom plate, the cushion blocks and the clamping blocks are arranged on the bottom plate in a staggered mode at intervals around the support column, the lower end of the rotating shaft is connected with the top of the support column through a bearing, a hand wheel is fixed to the top of the rotating shaft, one end of the connecting plate is fixed to the rotating shaft, and the digital dial indicator is installed at the other end of the connecting plate.
Preferably, the bottom plate is provided with a positioning column.
Preferably, the number of the cushion blocks and the number of the clamping blocks are three respectively, and the cushion blocks and the clamping blocks are fixed on the bottom plate in a staggered mode at intervals.

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. 1-2, a calibrating apparatus for a smoothness limit tester comprises a digital dial indicator 1, a connecting plate 2, a rotating shaft 3, a supporting column 4, a bottom plate 5, a cushion block 6 and a clamping block 7; the support column is fixed in the middle of the bottom plate, the cushion blocks and the clamping blocks are arranged on the bottom plate in a staggered mode at intervals around the support column as the center. The lower end of the rotating shaft is connected with the top of the supporting column through a bearing, a hand wheel 8 is fixed at the top of the rotating shaft, one end of the connecting plate is fixed with the rotating shaft, and the digital dial indicator is installed at the other end of the connecting plate. The reading of the digital dial indicator is more intuitive.
The bottom of some smooth gauges is provided with a positioning hole, and a positioning column 9 is arranged on the bottom plate according to the position of the positioning hole.
As shown in fig. 3, use smooth gauge 10 of hollow cone shape as an example, place the gage block on the cushion now, adjust the clamp splice position according to its bottom diameter, reuse bolt fastening, adjust the connecting plate in the height of rotation axis, make the measuring head of digital amesdial contact the top of smooth gauge, later fasten the connecting plate on the rotation axis, finally, the manual hand wheel that rotates, make digital amesdial revolve round smooth gauge top rotation a week, observe the reading of digital amesdial, if the upper portion surface is uneven, the reading can appear beating, reciprocal several times just can the accurate position of explaining, supply later stage to examine and repair, this calibrating installation can measure the upper surface or the lower surface of gauge, and is fast, moreover, the steam generator is simple in structure, it is convenient to detect, and is with low costs.
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.
