Target ball mounting seat can be divided into the target ball mounting seat that lining face is used according to the difference of measurement features, and the target ball mounting seat of measured hole position is measured the target ball mounting seat of right angle rib etc.Wherein, the target ball mounting seat of measured hole position utilize reference column target ball location and installation to the hole that needs are measured, then the target ball is placed on the target ball mounting seat.The baseline results of laser tracking measurement is the coordinate figure of the target ball centre of sphere, and the physical location of measured hole obtains by the radius of deflection of software compensation target ball and the offset distance of target ball mounting seat.The precision of measuring also comprises the manufacturing and the installation accuracy of target ball mounting seat except the measuring accuracy of laser tracker itself.
The target ball mounting seat of band reference column requires to cooperate for no gap between reference column and the measured hole.Clearance fit can make a side of reference column deflection measured hole and make measurement result have deviation, makes institute's measuring point coordinate not at the center of measured hole, and the hole axle tolerance fit between measured hole and the reference column is H7/f7 at present, and concrete gap is directly proportional with pore size.When the measured hole accuracy class is higher, can realize that no gap cooperates by improving target ball mounting seat reference column precision.But, when the precision of measured hole itself is hanged down, improve target ball mounting seat reference column precision and just can not realize that it cooperates with the no gap of measured hole.Therefore, the auto-centering target ball mounting seat of a kind of suitable low precision holes of design is very necessary.
Summary of the invention
The object of the invention provide a kind of at aperture size between 3mm-8mm, hole tolerance is less than IT12, the hole measurement that manufacturing accuracy is lower can reduce the alignment error of target ball mounting seat, is fit to the auto-centering target ball mounting seat of small-bore.
The technical solution adopted for the present invention to solve the technical problems is: a kind of auto-centering target ball mounting seat that is used for the small-bore comprises, the target ball installation head that has reference column, it is characterized in that: the spherical groove center, the axial outside of the big end step of target ball installation head, be provided with the cylindrical magnetic iron that attracts the target ball, hollow is made at the center of reference column, and hollow reference column face of cylinder total length is shaped on the cross section and is projected as cross stria.
The present invention has following beneficial effect.
The cylindrical magnetic iron of the target ball that is provided with in the heart in the target ball installation head spherical groove can attract target ball made of iron.The cross open hollow reference column in the aperture of 3mm-8mm is radially producing certain elastic deformation, the effect of the square fractal groove between cross stria and reference column and the target ball installation head is, can be to the clear angle of reference column root, make reference column insert measured hole smoothly, allow target ball installation head bottom and measured hole surface closely cooperate.Be shaped on opening cross stria on the hollow reference column, it is the open slot that is communicated with hollow hole, reference column is divided into four elasticity spacers, the elasticity spacer is made elastic deformation to the reference column axis, reference column and measured hole are closely contacted, eliminate both fit-up gaps between cooperating, can avoid the deviation that causes measurement result bigger, realize the purpose of self-centering fixed target ball.The plug of hole measurement reference column may produce certain damage of scraping to measured hole surface, and in most cases, because hole tolerance is not high less than the precision of the measured hole of IT12 itself, this influence of scraping damage can be ignored and do not remember.
