Description
Technical field
It the utility model is related to a kind of measuring device, in particular to a kind of measuring device of the axial float of grinding machine spindle.
Background technology
Grinding machine is the lathe for carrying out grinding to workpiece surface using grinding tool, and most grinding machine passes through high-speed rotating
Main shaft drives emery wheel to carry out grinding.And main shaft in rotation process there are axial float phenomenon, axial float just refer to turn
Axis inevitable minute movement in the axial direction at work.For the higher lathe of this kind of machining accuracy of grinding machine, grinding machine master
Influence of the axial float of axis to machining accuracy is very notable, and the amount of feeding that axial float directly results in emery wheel changes,
Cannot be guaranteed the processing quality of product.
Therefore, the axial float error amount of national regulation, traditional axis to grinding machine spindle are provided with for grinding machine spindle
Mainly measured to the detection method of play using manually control amesdial, and measurement position is generally center edge.
Its reason is that the centre bit of main shaft end face is equipped with a centre bore, so the gauge head of amesdial cannot steadily be fixed on centre bit
Put, cause the center that can not measure main shaft end face, thus can only be near measuring center hole position.And traditional measurement side
Method manually reads data, the change at data moment, the reading tool for axial transmission value using worker during main axis
There are larger subjective factor and uncertain factor.
In addition, main axis is there are axial float and radial-play phenomenon, and appeals measuring method due to amesdial
The position of gauge head is not at the center of main shaft end face, therefore the stagger that the radial-play of measurement position is brought will influence main shaft
The actual value of axial float, makes measurement result produce error.
The content of the invention
In view of the deficienciess of the prior art, the purpose of this utility model is to provide in a kind of end face to grinding machine spindle
Heart position measures, so as to more accurately measure a kind of measuring device of the axial float of grinding machine spindle of axial float.
To achieve the above object, the utility model provides following technical solution：Grinding machine is provided with main shaft and drive shaft
The motor of rotation, main shaft measurement end face are provided centrally with centre bore, including amesdial and the installation for installing main shaft
Seat, the amesdial include the Measuring plate with registration and the gauge head being equipped with Measuring plate, it is characterised in that：Further include
