Abstract
The utility model relates to a radial run-out detector used for a shaft and belongs to the field of radial run-out detection devices used for shaft type work pieces. The radial run-out detector used for the shaft is simple in structure and wide in measurement range. Two adjustable top tips are arranged. The flexible top tips can be adjusted according to the sizes of the work pieces, so that the work pieces of different sizes can be measured. A dial indicator is arranged on an indicator support. The indicator support is fixed on a cross beam and is capable of moving in a reciprocating manner and the dial indicator is capable of moving up and down on the indicator support. A radial run-out value of the shaft can be measured accurately. Therefore, a wasting phenomenon caused by discarding the work pieces by mistake since the work pieces are judged wrongly to be in bending deformation without a detection instrument when a fitter is repairing can be eliminated.
Description
Technical field
The utility model relates to a kind of radial jitter detector for shaft, and it belongs to shaft-like workpiece diameter run-out checkout equipment field.
Background technology
Along with the development of industry, lathe and grinding machine are widely used in axle, dish, cover and other have the manufacture field of the workpiece of rotary surface, particularly the bearing machining field.At present, the little shaft run-out of the main spindle box of lathe, grinding machine and other gear train, the measurement of right alignment mainly are to estimate definitely by the workman, and its error range is larger, when being operated in maintenance, the easily little bending shaft distortion of false judgment, thus the phenomenon of scrapping produced, cause the wasting of resources.Thereby the detector of a kind of little shaft run-out, right alignment is imperative.
Summary of the invention
In view of the problem that existing procucts exist, the purpose of this utility model be to provide a kind of be applicable to small axle diameter to beat, the detector of coaxality measurement.
To achieve these goals, the technical scheme that the utility model will provide is a kind of radial jitter detector for shaft, it mainly comprises: the sliding bearing guide rail, the first adjustable centre, dial gauge, dial framework and the second adjustable centre, the first adjustable centre and the second adjustable centre are tangent with guide rail respectively, the built-in spring of the first adjustable centre, the first adjustable centre and the second adjustable centre are by being fixed in set bolt on the top fixed mount, top fixed mount is fixed on the rail plate, crossbeam is fixed on the sliding bearing guide rail by screw and nut, and dial framework hangs on the crossbeam dial gauge and hangs on the crossbeam and by dial framework and fix.
Described dial framework is done transverse movement at crossbeam.
Described dial gauge moves up and down at dial framework.
Principle of work of the present utility model:
The second adjustable centre is fixed by set bolt, detected little axle is put between the first adjustable centre and the second adjustable centre, adjust the elasticity of workpiece for measurement between the first adjustable centre and the second adjustable centre by the spring in the first adjustable centre, the manual rotation workpiece for measurement, mark transverse movement on the moving beam, drive the dial gauge transverse movement, regulate dial gauge to the position to be measured of workpiece for measurement, regulate the position of dial gauge and dial framework, make the sharp detected part of beating at workpiece for measurement of dial gauge mark, carry out reading by the dial gauge pointer, the difference between maximal value and the minimum value is right alignment, the diameter run-out value.
The utility model has the advantage of: simple in structure, measurement range is extensive, is provided with two adjustable centres, can adjust rolling center according to the size of workpiece, measures the workpiece that varies in size; Dial gauge is located at dial framework, and the dial framework frame is fixed on the crossbeam, can move reciprocatingly and move up and down, and accurately measures the diameter of axle to jitter values, avoids pincers worker when maintenance, is not mistaken for flexural deformation because there being detecting instrument, and then scraps the wasting phenomenon of generation.
