Abstract
The utility model relates to mechanical workpiece tolerances measuring devices, in particular to a workpiece coaxiality measuring device. Two rotating wheels are abreast arranged at upper ends of vertical supports respectively, and two rotating wheels of one of the vertical supports are coaxial with two rotating wheels of the other vertical support. A movable dial indicator support is fixedly connected to a horizontal bottom plate and is provided with a dial indicator. A head of the dial indicator is exactly contacted with an external surface of the workpiece. Working process includes placing the cylindric workpiece horizontally on the rotating wheels, and moving the movable dial indicator support and adjusting the dial indicator to contact the head of the dial indicator to the external surface of the workpiece; turning the workpiece by hands, observing changes of a pointer of the dial indicator after the workpiece rotates a circle, and finally obtaining a coaxiality deviation of the workpiece. The workpiece coaxiality measuring device has the advantages of simple structure, flexible rotating, and convenience in operation, high working efficiency, reliable measurement, small error and measurement accuracy guarantee.
Description
Technical field
The utility model relates to mechanical workpieces tolerance measurement device, particularly a kind of device of workpiece coaxality measurement.
Background technology
Many workpiece are because volume is large, Heavy Weight, be difficult to as general part clamping and measure the right alignment of its endoporus and outer ring as System of Rotating about Fixed Axis on chuck, 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 purpose of this utility model is for above-mentioned shortcomings and deficiencies of the prior art, the workpiece coaxality measuring mechanism that provides a kind of easy to operate, high efficiency, measuring accuracy to guarantee.
The purpose of this utility model is realized by following technical scheme.
A kind of workpiece coaxality measuring mechanism comprises a horizontal base plate, two vertical supports; Two vertical supports vertically are fixed in respectively the horizontal base plate, and both are over against placement; It is characterized in that: the upper end at each vertical support is provided with respectively two rotor wheels side by side, and two rotor wheels of a vertical support are coaxial with two rotor wheels of another vertical support respectively, and described rotor wheel is movably connected on the vertical support by rolling bearing; During work, two of workpiece corrects and is placed on respectively on two groups of rotor wheels placed side by side; Also be fixedly connected with a movable dial framework on described horizontal base plate, be provided with a dial gauge on movable dial framework, the gauge outfit of dial gauge is just in time touched on the outside surface of workpiece.
Further, be respectively equipped with a deep floor between described horizontal base plate and two vertical supports.
Further, be provided with set screw in the bottom of described horizontal base plate.
Compared with prior art, workpiece coaxality measuring mechanism described in the utility model has following advantage: during work, cylindric workpiece level is placed on rotor wheel, mobile movable dial framework is also adjusted dial gauge, make the gauge outfit contact outer surface of workpiece of dial gauge, use the hand turning of work piece, like this along with one week of workpiece rotating, the pointer of observing on dial gauge changes, and just can measure the workpiece coaxiality deviation.Regulate the gauge outfit diverse location on the outer surface of dial gauge, 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.

Embodiment
Further describe structure of the present utility model below in conjunction with accompanying drawing.
A kind of workpiece coaxality measuring mechanism comprises a horizontal base plate 1, two vertical supports 2; Two vertical supports 2 vertically are fixed in respectively horizontal base plate 1, and both are over against placement; Upper end at each vertical support 2 is provided with respectively two rotor wheels 3 side by side, and two rotor wheels 3 of a vertical support 2 are coaxial with two rotor wheels 3 of another vertical support 2 respectively, and described rotor wheel 3 is movably connected on vertical support 2 by rolling bearing 4; During work, two of workpiece 5 corrects and is placed on respectively on two groups of rotor wheels placed side by side 3; Also be fixedly connected with a movable dial framework 7 on described horizontal base plate 1, be provided with a dial gauge 6 on movable dial framework 7, the gauge outfit of dial gauge 6 is just in time touched on the outside surface of workpiece 5.
During work, cylindric workpiece level is placed on two groups of rotor wheels placed side by side 3, mobile movable dial framework 7 is also adjusted dial gauge 6, make gauge outfit contact workpiece 5 outside surfaces of dial gauge 6, with hand turning of work piece 5, along with workpiece 5 rotates a circle, the pointer of observing on dial gauge 6 changes, and just can measure workpiece 5 coaxiality deviations like this.Regulate the gauge outfit diverse location on the outer surface of dial gauge 6, 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.
Be respectively equipped with a deep floor 8 between described horizontal base plate 1 and two vertical supports 2, strengthened the structural strength of device.
Bottom at described horizontal base plate 1 is provided with set screw.During measuring workpieces, can reconcile the height of horizontal base plate 1 according to the size of workpiece, measurement range is extensive.
Above demonstration and described ultimate principle of the present utility model and principal character and advantage thereof.The technology personage of the industry should understand; the utility model is not subjected to the restriction of above-mentioned implementing regulations; what describe in above-mentioned implementing regulations and instructions is to be used for illustrating principle of the present utility model; under the prerequisite that does not break away from the utility model principle and scope; the utility model also can have various changes and modifications, and these changes and improvements all belong in claimed the utility model scope.
The claimed scope of the utility model defines with appending claims and other equivalent.
