Description
Technical field
The utility model is related to a kind of two devices of Different Plane axis hole hole heart axes perpendicularity of detection.
Background technology
In machine-building, the distance (Perpendicularity) for being vertically point to straight line is position of related features, uses symbol
⊥ is represented.When theoretical correct angle is relative to 90 degree of tolerance percentages of generation of datum level, referred to as squareness tolerance.When with plane
On the basis of when, if element to be measured is plane, the distance of its squareness tolerance band is referred to as tolerance range for the tolerance value of perpendicularity.Hang down
Straight measurement survey protractor or perpendicularity measurement instrument.When element to be measured is linear axis, the tolerance value of perpendicularity represents axle and puts down
Angle alleged by face makes the difference with 90 degree, the tolerance percentage of generation.Different two straight lines in any one plane are called antarafacial
Straight line (skew lines).A little and in plane in any straight line and plane without the straight line of the point it is different by outside plane
Face straight line, feature be it is both not parallel, it is also non-intersect.Angle formed by two different surface beelines is arbitrarily taken a bit in space, then
This point is crossed to do two straight lines respectively and obtain parallel lines, now this two parallel lines institutes into angle is " two different surface beeline institutes
Into angle ".Two different surface beeline institute angulations are that the parallel lines a, b, a, b for making two different surface beelines respectively by space any point O are vertical
O is met at, but two different surface beelines have no common point, at 90 degree, claim two straight lines vertical.This two straight line a, b institutes angulation [0 degree, 90 degree]
Cry different surface beeline into angle.Axial workpiece belongs to rotating body parts, mainly by the surface such as the face of cylinder, circular conical surface, screw thread and keyway structure
Into its length is more than diameter.Optical axis, hollow shaft, semiaxis, multi-diameter shaft, special-shaped axle (cross can be divided into again according to its planform
Axle, eccentric shaft, bent axle, cam).There is wanting for the aspects such as circularity, cylindricity, axiality, perpendicularity in addition to diameter accuracy requirement
Ask.The design basis of axial workpiece is the axial connecting line of its bearing journal, and by " unifying datum " principle, often the both ends of the surface in axle add
Work goes out centre bore and processes each section of external cylindrical surface as unified positioning reference plane;Or positioned with cylinder and center complex;Shorter
Axle then directly uses excircle orientation.The axis of rotation of two neighboring shafting should keep vertical and intersect in same plane in space,
But due to equipment manufacture, assembling, control and thermal deformation, friction in motion process, vibrate and the factor such as inertia influence so that
Two axial lines are definitely coplanar not to be reached, and is two different surface beelines, the Intersection of two orthogonal shaftings in real work space
Error is the length of space two axial lines line segment common vertical line section.It is generally acknowledged that axis intersection also regard as between average axis of rotation,
The error project not influenceed by Shaft angle position and shaking volume.The error of perpendicularity of axis be two orthogonal shaftings axis it
Between deviation of the angle with 90, the error of perpendicularity can change according to the rotational angle of rotation axis system and position in itself, axis
Perpendicularity is very big to the comprehensive influence pointed to.It is generally acknowledged that the error of perpendicularity is fixed value, not by turn error and average axis
Between error influence.Axis of rotation is the line of the centre of gyration, and under without any error condition, the point of contact in rotating shaft is all enclosed
Circled around axis of rotation, the center of circle of the circular motion is the centre of gyration of rotating shaft.As can be seen here, two axles of direct detection
It is that two hole perpendicularities are relatively difficult.Currently manufactured Intersection, two axis hole part common practices of perpendicularity are by two
Secondary clamping parts, then process holes respectively, due to fixture error and lathe error factors in itself, can not finally reach
Key on to drawing such issues that two requirements of shafting holes axis verticality, solution is that transition lines line is vertical, line face is hung down
Directly, face face is vertical.Measurement in current production scene to two axis hole heart line perpendicularity of Different Plane there is no complete measurement
Method means, even if the use of three coordinate measuring machine in recent years, the axis hole heart line squareness measurement to two Different Planes also shows
Obtain helpless, and be not practical.Traditional motive Axle mould intends the method for playing table, and the simple mechanical precision by device ensures
Certainty of measurement, it is difficult to truly reflect the error state of part, credible rate is very low,
In the product or parts of profile and structure very irregular, two mutually perpendicular different surface beeline key elements have given
The design requirement of orthogonal both direction and given any direction squareness tolerance, and design requirement can not use line pair
Face squareness tolerance is solved, in design, manufacture and when checking, such issues that with regard to no national standard according to can look into,
And be largely exist such issues that in enterprise.In order to solve the problem of detection perpendicularity, the utility model provides one
Antarafacial central axis degree testing agency is planted, the size that the mechanism is applied to design of part in Fig. 1 such as is Ф 18+ 0 0.019The water of mm
It is flat to treat that the relative size of gaging hole 4 vertically treats the detection of the perpendicularity of gaging hole 3 for Ф 6+0.013 0mm.
