Abstract
The utility model discloses a big work piece axiality measuring device, its structure is equipped with the support on the horizontal bottom plate, sets up two axis of rotation that are equipped with the rotation wheel on the support, rotate the wheel external diameter and equal, two axis of rotation are parallel to each other and with the bottom plate on the plane height, place the activity table frame that is equipped with the percentage table on the bottom plate. Preferably, a rolling bearing is arranged at the matching part of the rotating shaft and the bracket, and one end of one rotating shaft is provided with a rotating handle. The utility model discloses simple structure, preparation are easy for big work piece axiality is measured, convenient operation rotates in a flexible way, and work efficiency is high, measures reliably, the error is little, can guarantee measurement accuracy.
Description
Technical field
The utility model relates to mechanical component form and position tolerance measurement mechanism, especially for the device of coaxiality of large workpiece measurement.
Background technology
Large-scale workpiece is because volume is big, Heavy Weight, be difficult on chuck, rotate the right alignment of measuring its endoporus and cylindrical as dead axle as the such clamping of part, usually adopt degree of depth caliper measurements workpiece opposite side wall thickness to compare, could roughly understand coaxiality deviation after taking multiple measurements conversion.Obviously use degree of depth caliper measurements, not only troublesome poeration, efficient are low, and measuring accuracy is difficult to assurance.
The utility model content
The measuring apparatus for coaxiality of large workpiece that the purpose of this utility model is to provide a kind of easy to operate, high efficiency, measuring accuracy to guarantee.
The technical solution of the utility model is: the horizontal base plate is provided with support, two rotation axiss that rotor wheel is housed are set on the support, two rotation axiss be parallel to each other and with base plate on the plane contour, described rotor wheel external diameter equates, places the movable dial framework that dial gauge is housed on the base plate.
Further scheme is: one of described rotation axis is minor axis, and one is major axis, and an end of major axis is provided with swing handle; There is rolling bearing the cooperation place of described rotation axis and support; Respectively adorn two rotor wheels on the described rotation axis; The bottom of described base plate is provided with set screw.
During work, cylindric big work piece hoisting is got up to lie in a horizontal plane on the rotor wheel, and axis of workpiece is parallel with rotation axis, moves movable dial framework and adjusts dial gauge, make dial gauge gauge head contact workpiece bore area, swing handle drives Workpiece Rotating by rotor wheel, as not establishing handle then, also can directly use the hand turning of work piece, along with one week of Workpiece Rotating, the pointer of observing on the dial gauge changes, and just can measure the workpiece coaxiality deviation like this.Regulate the diverse location of dial gauge gauge head in endoporus, just can measure the right alignment at diverse location place.This apparatus structure is simple, rotation is flexible, easy to operate, and high efficiency is measured reliably, and error is little, can guarantee measuring accuracy.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Referring to accompanying drawing, base plate 1 is provided with support 2, and two rotation axiss that rotor wheel 3 is housed are set on the support 2, and wherein one is minor axis, one is major axis, one end of major axis 4 is provided with swing handle 9, and rotation axis and support cooperation place have 5, two rotation axiss of rolling bearing to be parallel to each other, and with base plate on the plane contour, adorn two rotor wheels on the every rotation axis, all rotor wheel external diameters equate that there is set screw 10 bottom of base plate 1 for four jiaos.During work, workpiece 6 is bearing on the rotor wheel, and the gauge head that is contained in the dial gauge 7 on the movable dial framework 8 contacts with the workpiece bore area.
