Abstract
The invention discloses a large workpiece coaxiality measuring device which is structurally characterized in that a support is arranged on a horizontal bottom plate, two rotating shafts provided with rotating wheels are arranged on the support, the outer diameters of the rotating wheels are equal, the two rotating shafts are parallel to each other and are as high as the upper plane of the bottom plate, and a movable meter frame provided with a dial indicator is arranged 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 invention has simple structure, easy manufacture, convenient operation, flexible rotation, high working efficiency, reliable measurement and small error, is used for measuring the coaxiality of large workpieces and can ensure the measurement precision.
Description
Technical field
The present invention 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.
Summary of the invention
The measuring apparatus for coaxiality of large workpiece that the object of the present invention is to provide a kind of easy to operate, high efficiency, measuring accuracy to guarantee.
Technical scheme of the present invention 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 a structural representation of the present invention.
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.
