Description
Technical Field
The utility model relates to a flatness detection device, in particular to a circular ring type reference flatness detection device.
Background
The existing detection device is single in comparison, not strong in adaptability and relatively low in detection precision.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the defects in the prior art, and provides the circular ring type reference flatness detection device which is compact in structure, can be widely applied to various circular ring type parts needing to measure the flatness of the reference surface, and is simple in shape change and low in shape change cost only by replacing a limiting plate during shape change.
The technical problem of the utility model is mainly solved by the following technical scheme:
the utility model provides a ring class datum plane degree detection device, includes datum plate and detection work piece, the upper portion of datum plate be equipped with the detachable limiting plate, the limiting plate will detect the work piece location on the datum plate, the bottom of detecting the work piece be equipped with the amesdial that is used for detecting the work piece.
Preferably, the limiting plate is arranged in the detection workpiece, the outer edge of the limiting plate is fixed to the inner end of the detection workpiece, and the limiting plate and the reference plate are fixed through fastening bolts.
Preferably, the reference plate is arranged at the upper part of the bottom plate, and four corners of the bottom plate are respectively provided with supporting legs.
Preferably, the contact end of the dial indicator sequentially penetrates through the bottom plate and the reference plate to be in contact with the bottom of the detection workpiece, and the dial indicator is fixed with the bottom plate through the locking screw rod.
The workpiece is positioned by the limiting plate to rotate uniformly and manually, so that the workpiece reference surface is in continuous contact with a gauge needle measuring head of the dial indicator, and the flatness of the workpiece reference surface is accurately obtained.
The assembling method comprises the following steps:
the four supporting legs are correspondingly fastened in screw holes on the four sides of the bottom plate respectively, whether height differences of the fastened four supporting legs generate shaking or not is checked, and the height differences are adjusted to ensure that the four supporting legs are consistent in height and stable in placement. Blow the bottom plate out with the air gun, the dust greasy dirt of datum plate contact surface etc. lightly put the datum plate and fix it firmly with two M6 hexagon socket head cap screws on the bottom plate plane, pass the bottom plate with the amesdial measuring bar afterwards, datum plate adjusting position makes the gauge head of amesdial surpass datum plate 1mm, and with locking screw with amesdial rigidity, blow out stop device with the air gun, according to the corresponding position of adjusting stop device of work piece size, the plane center that makes the part can contact the amesdial gauge head, lock the limiting plate.
The measuring method comprises the following steps:
the surface is measured to the part that will need the measurement and is wiped clean, measures on the surface puts into the limiting plate downwards, and the hand is slightly with strength to press the part and carry out clockwise or 360 rotations anticlockwise, and is undulant through the numerical value of observing the amesdial, comes the accurate plane degree of judging this part reference surface.
The device for detecting the ring-type reference flatness further improves the detection speed and precision and enlarges the adaptability.
