Upper surface at above-mentioned back-up block is provided with axle bed, and said axle bed is the rectangle plate body.Offer the slotted eye that is used for place work piece (axle) at its end face; The cross section of said slotted eye is " V " shape; And the side of slotted eye links to each other with the both sides of axle bed; Between axle bed and back-up block, be provided with the variable valve (for example screw) that is used to adjust the axle bed height, be provided with limiting plate in a side of axle bed, the bottom supports of said limiting plate is fixed on the upper surface of back-up block through screw; And the top margin of limiting plate and the sub-maintenance level of survey, on limiting plate, be provided with the limit valve (for example screw) that is used to regulate workpiece (axle) axial location.
The present invention is work like this:
The operator is placed on workpiece (axle) on the axle bed, guarantees to survey the external diameter that son can touch workpiece, the height of adjustment axle bed and the axial location of workpiece; And according to the number in step footpath and the position (this action is through the positioning seat adjustment) of distance adjustment survey; The extension elongation sub (this action is through the adjustment of the standing valve on the locating piece) according to the size adjustment survey of workpiece external diameter, with the sub measuring position of adjusting to each footpath of workpiece of survey, and the sub-contact workpiece external diameter of the survey of both sides; Utilize micro motor to drive Workpiece Rotating; During Workpiece Rotating, survey the subband gonosome of moving and change, the distance between the inner catch of elastic body changes; Whether data are reflected on the computing machine through sensor, qualified through the computer judges measured value.
The present invention has following advantage: measure accurately, production efficiency is high, good product quality, reduction labour intensity, reduce production cost.
