Description
Technical field
The utility model relates to a kind of flatness checking device, specifically a kind of simple combination formula well lid flatness detection
Device is mainly used to carry out well lid product the detection of flatness, is also applicable to other similar have flatness testing requirements
Product, such as casting, weldment, machined piece.
Background technique
Flatness is the deviation for macroscopical height of concave convex relative ideal plane that product surface has, and measurement refers to tested real
Border plane is to the variation of its ideal plane, as flatness error.
In casting and mechanical processing industry, the piece surface after blank surface or machining through casting, flatness
There are technical requirements, it is necessary to judge whether it is qualified after measuring.In addition, if the casting of casting further will be machined,
Also it should first determine whether its flatness meets the requirement of machine-finish allowance, it, may if without inspection and if directly processing
Cause to process unqualified, causes the waste of cost.
Flatness error is measured, common method has: clearance gauge gap method, optical interference method, indicator mensuration etc..
Optical interference method: principle of optical interference is utilized, flatness error value is determined according to shape of interference fringe, item number
Method.When measurement, ideal plane is embodied using the working face of optical parallel, is directly determined with the bending degree of interference fringe tested
The flatness error value on surface.It can be used for measuring facet, such as the working face of gauge and putting down for micrometer gauge head measuring surface
Face degree error etc. can be used for 0-30 meters of measurement range of product.
Facet measuring device precision is high, is mostly whole complete set of equipments, and inconvenience is mobile, and measurement range is limited.Large laser
Measuring device cost is very high, long using time, and when same type typical products in mass production is tested, there are many preparation non-cutting time,
And precision instrument service life and precision in plant site working environment are easily reduced, therefore optical interference method discomfort alloying
The measurement of the medium-and-large-sized size, aximal deformation value product in places such as make, machine, welding.
Indicator mensuration: indicator mensuration is the flatness error using the measuring device equipped with indicator to workpiece
It measures.When measurement, tested part is placed on dressing plate, using dressing plate as measurement datum, along workpiece reality
Surface is measured by the point-by-point traverse measuring device of certain arrangement form (or travelling workpiece).Indicator is in entire actual surface
The maximum variation measured is the flatness error of the actual surface.Indicator mensuration is divided into line-of-sight course by evaluation datum level
And diagonal method.Line-of-sight course is to use 3 points of ideal planes determined of lie farthest away in tested actual surface as evaluation benchmark
Face, when actual measurement, are first adjusted to contour with dressing plate for 3 points of lie farthest away in tested actual surface；When diagonal method is surveyed
Four angle points in actual surface are first adjusted to contour two-by-two by diagonal line, are then measured with indicator.
Above method needs when measuring by 3 points or two cornerwise angle point tune of lie farthest away on test product surface
It is whole to contour with dressing plate, adjustment process is more time-consuming, moreover, it is point-by-point to need continuous movement indicator to carry out when measurement
Measurement, measurement are unsuitable for batch quickly detection than relatively time-consuming.In addition, this method is also unsuitable for the measurement of planeness of larger workpiece.
