Description
Technical field
The invention belongs to the probes in mechanical gauge check field more particularly to a kind of flatness checking device.
Background technology
Flatness refers to the deviation for macroscopical height of concave convex relative ideal plane that substrate has.Tolerance range is that distance is tolerance
Region between two parallel planes of value t.Flatness belongs to the form error in Form and position error.
The measurement method generally used is：The same X-shape of several height is put on granite platform holds block, is used for
Workpiece is held.Call in a high metric, it is domestic or import can, in the probe part of high metric, there are one rectangular scribing line
Knife takes off it, then processes the square block of a root long point, then the end of the square block in this root long installs one thousand points additional
Table keeps the measuring staff direction of amesdial vertical with workpiece surface, is fabricated to an easy face measuring instrument.Rotation height advises hand
Handle makes amesdial gauge head encounter working surface, allows amesdial reading to be zeroed, gauge head is moved on to position to be detected, reads amesdial
Reading is either with or without more than preset tolerance.
Between bearing face grinds manufacturing procedure, for bearing ring, the reference plane of the plane of lasso as later process,
Its flatness is extremely important, if face is not whole for the flatness of bearing ring, later process grind ditch, grinding out, superfinishing precision by nothing
Method ensures.The precondition of milled bearing ring flatness is exactly that the flatness of grinding wheel in equipment and the flatness on chassis are wanted
It is good.Using above-mentioned simple flatness measuring instrument, error is larger, can not be adapted in production now.
Plane of grinding wheel and chassis plane are to repair to come by trimmer at present, if the movement locus and chassis axle of trimmer
Or grinding wheel spindle rotation center out of plumb when, it is just uneven to repair the plane come.The measurement flatness that production scene is commonly used
Measurer is knife-edge ruler, by knife-edge ruler and plane contact, checks the light leakage rate of knife-edge ruler and tested part.If can see apparent
Light leakage position is exactly the sunk position of plane.Check that the method precision of flatness is very low, does not meet the height of present day devices in this way
Required precision.
