Tail sliding rail, supporting block bottom end open up and the matched dovetail groove of dovetail sliding rail.
According to the length of axis, the supporting block that movement can be slided tightens fixing bolt, armature spindle is placed to suitable position
It is fixed in the V-groove of two supporting blocks, in digital display dial gauge setting to the supporting block that can be slided, regulates digital display thousand and divide
The position of table and armature spindle, manual jiggering, i.e. hand take spanner to rotate armature spindle, measure record data, determine if to meet same
The requirement of axis degree.
It is further preferred that the dovetail groove top of supporting block bottom end opens up ventilating groove.It is slided more between supporting block and sliding rail
It is unobstructed.
It is further preferred that corresponding ventilating groove, dovetail rail tips open up sliding slot.It is slided between supporting block and sliding rail more logical
Freely.
It is further preferred that supporting block two bottom sides are equipped with auxiliary positioning plate.Reinforce support bulk strength, it can be ensured that turning
Sub- axis is supported well, it is ensured that it is accurate to measure.
It is further preferred that auxiliary positioning board bottom portion is adapted setting with bottom plate.
It is further preferred that corresponding fixing bolt, auxiliary positioning plate are equipped with mounting hole.When tightening bolt, bolt enters
Into mounting hole, clamping supporting block.
It is further preferred that mounting hole is threaded hole.For bolt with threaded hole by screw-thread fit, fastening effect is more preferable.
The art of this patent technical problem to be solved is to provide a kind of simple in structure, and easy to use, duty is small, environment
It is of less demanding, it is small using limitation, have the concentricity test measuring device of nonexpondable function.In order to achieve the goal above,
The position for placing axis uses v block, and entirety uses stainless steel, and material is hard, and non-corrosive is unlikely to deform, it is only necessary to one
A chain-wales can be installed；Digital display dial gauge is adsorbed on by magnetic base on sliding v block, is satisfied with to each position of axis
It measures；
Compared with prior art, the utility model has the beneficial effects that：
1, the utility model can accurately measure armature spindle concentricity, simplify repair by the way that bottom plate and supporting block is arranged
Work, simple in structure, duty is small, and environmental requirement is not high, small using limitation, has a wide range of application, and can be applied to add without machinery
The factory of work；
2, by the way that V-groove is arranged in supporting block, contact surface is small, and frictional force is small, places left-hand seat turn and moves laborsaving, and error is small,
It is not easy to wear；
3, by the way that V-groove is arranged in supporting block, it can facilitate and simply detect the different diameters of axle and on a long axis
The concentricity of different location greatly reduces human cost, time cost, manufacturing cost.
