The fixing protector of three-dimensional coordinate tracker target ballTechnical field
The present invention relates to field of precision measurement, and in particular to the fixing protector of three-dimensional coordinate tracker target ball.
Background technology
In field of precision measurement, laser interferometry techniques with its noncontact, high precision, can trace to the source the advantages of turn into superThe effective technology means of accurate measurement, are widely used in the static state such as gauge calibrating, lathe calibration and nano-sensor demarcationThe accurate measurement occasion of geometric sense.Measuring instrument based on laser interferometry techniques is a lot (for example：Laser interferometer, laserTracker), the cooperation of reflecting prism is required to, spherical reflection is typically used for the speculum of the tracker with following functionDevice, its centre of form is overlapped with photocentre.
Laser tracker needs the cooperation of target ball in measurement process, if the motion of real-time tracking certain point, in addition it is also necessary to willThen target ball absorption is realized target ball and measured position by the absorption of magnetic ball seat in position of interest in the detent of ball seatThe fixation put.However, with the development of modern material, increasing alloy material, meet materials application in manufacturing industry, magneticThe application of ball seat is restricted, it is impossible to is met the condition of measurement, be greatly limit the application of tracker.Simultaneously because frock formThe complexity of diversity and structure, the angle of target ball can not be adjusted, thus cause to produce between target ball and laser tracker to block,It can not normally receive and reflection laser.
The content of the invention
The technical problems to be solved by the invention are that the application of magnetic ball seat is restricted, it is impossible to meet the condition of measurement,The angle of target ball can not be adjusted, thus cause to produce between target ball and laser tracker to block, it is impossible to normally received and swashed with reflectionLight, it is therefore intended that the fixing protector of three-dimensional coordinate tracker target ball is provided, the use of magnetic ball seat is ensure that, also simultaneouslyThe angle position of target ball can be adjusted to meet different demands, the efficiency of measurement is improved.
The present invention is achieved through the following technical solutions：
The fixing protector of three-dimensional coordinate tracker target ball, including magnetic force ball seat, the magnetic force ball seat are provided with band magneticProperty groove, groove be used for fix target ball, the surrounding of magnetic force ball seat offers the tapped through hole of multiple levels, tapped through holeInterior to be provided with screw rod, one end of the tapped through hole, which is located at below groove, magnetic force ball seat, is connected with vertical rotary shaft, the rotationThe lower end of rotating shaft is connected with spill spin block, and rotary shaft rotates around own axes, is arranged with spill spin block horizontally disposedFix bar, spill spin block rotates around fixed rod axis；Firm banking is connected with below fix bar.
The fixing protector of the present invention, ensure that the use of magnetic ball seat, while target ball can also be adjustedThe efficiency of measurement is improved to meet different demands in angle position.It can be realized the good solid of ball by magnetic grooveIt is fixed, meanwhile, by screwing screw rod so that the end of screw rod and target ball exact contact, further improve its stability；Pass throughRotary shaft and spill spin block can adjust the angle of magnetic ball seat and target ball, so that target ball need not movedIn the case of realize angle position adjust.
The two ends of the fix bar are connected by vertical height regulating rod respectively, so as to adjust the height of target ballPosition is spent, the firm banking includes inverted U plate, and the bottom of height regulating rod passes through the top surface of inverted U plate, the side of inverted U plateFace is connected with standing screw respectively, by the way that the somewhere of measured workpiece to be caught in the lower end of inverted U plate, then tighten standing screw with up toTo fixed effect.
Height regulating rod is flexibly connected with the top surface of inverted U plate, so in fixed workpiece, can be adjusted by lifting heightPole is so that then its target ball tightens standing screw so that the side of inverted U plate and measured workpiece in suitable heightAnd be firmly secured to together between height regulating rod.
Magnetic force ball seat is provided with protective cover, and the shape of the protective cover and target ball matches, and protection is played to target ballEffect, it is to avoid be collided etc. and to cause economic loss.
Magnetic force ball seat bottom be provided with chute, rotary shaft and between Magnetic force ball seat basal sliding connect, Magnetic force ball can be causedSeat is moved forward and backward in the horizontal direction.
The present invention compared with prior art, has the following advantages and advantages：
1st, the fixing protector of three-dimensional coordinate tracker target ball of the present invention, ensure that the use of magnetic ball seat, simultaneouslyThe angle position of target ball can also be adjusted to meet different demands, the efficiency of measurement is improved；
2nd, the fixing protector of three-dimensional coordinate tracker target ball of the present invention, the two ends of fix bar pass through vertical height respectivelySpend adjusting rod to be connected, so as to adjust the height and position of target ball, the firm banking includes inverted U plate, and height is adjustedThe bottom of bar passes through the top surface of inverted U plate, and the side of inverted U plate is connected with standing screw respectively, by by the somewhere of measured workpieceThe lower end of inverted U plate is caught in, then tightens standing screw to reach fixed effect；
3rd, the fixing protector of three-dimensional coordinate tracker target ball of the present invention, magnetic force ball seat is provided with protective cover, the guarantorThe shape of shield and target ball matches, and target ball is played a protective role, it is to avoid is collided etc. and to cause economic loss, magnetic forceBall seat bottom be provided with chute, rotary shaft and between Magnetic force ball seat basal sliding connect, magnetic force ball seat can be caused in the horizontal directionOn move forward and backward.
