Scheme of installation.
Specific embodiment
As shown in figure 1, column 1 is uprightly placed, the guide rail 2 being arranged on column 1 is in edge-on state.The magnetic of the present invention
Absorption linearity measurer includes fixing end 3 and mobile terminal 4.Fixing end 3 is fixedly installed on column 1, and mobile terminal 4 is arranged
Move can on guide rail 2 and along guide rail 2.
As shown in Fig. 2 fixing end 3 includes fixing end connecting plate 31, optical-autocollimator 32, autocollimator bearing 33.Gu
Fixed end connecting plate 31 is fixedly connected by multiple soket head cap screws 35 with column 1.Autocollimator bearing 33 is in inverted "L" shaped, and it erects
Front is fixedly connected by soket head cap screw 34 with fixing end connecting plate 31, and its horizontal side arranges optical-autocollimator 32,
In present embodiment, optical-autocollimator 32 adopts upper machine HYQ03-84070 type autocollimator.
As shown in figure 3, mobile terminal 4 include magnetic base 41, bridge plate 42, mobile terminal connecting plate 43, mirror mount 44 with
And speculum 45 (supporting with autocollimator).Bridge plate 42 is in " recessed " shape.Magnetic base 41 is rectangle, and its one end is arranged on bridge plate 42
Depression in, with bridge plate 42 grafting naturally it is also possible to make it fixing more firm using modes such as interference fit, pass through afterwards
Soket head cap screw 46 is fixing.The other end of magnetic base 41 respectively with the A face (vertical plane) of guide rail 2 and B face (horizontal plane) strong
Fit tightly under magneticaction.Soket head cap screw 46 will be fixing with magnetic base 41 for bridge plate 42, and connecing with bridge plate 42 at it
Spring washer for reducing abrasion and packing ring are disposed with contacting surface.Mobile terminal connecting plate 43 is vertically arranged, and uses countersunk head
Screw 47 is fixing with bridge plate 42.Mirror mount 44 is in equally inverted "L" shaped, and soket head cap screw is passed through with mobile terminal even in its vertical side
Fishplate bar 43 is fixedly connected, and its horizontal side arranges speculum 45.
It will be recognized by those skilled in the art that in the present embodiment using fixing end connecting plate 31 and mobile terminal connecting plate 43 being
In order to coordinate autocollimator bearing 33 and mirror mount 44 so as to can more structurally sound fixation above.Work as autocollimator
When the structure of bearing 33 and mirror mount 44 is easy to them and can directly be assembled, fixing end connecting plate 31 and mobile terminal are even
Fishplate bar 43 can be omitted.
During use, first fixing end connecting plate 31 is fastenedly connected with screw with column 1, and optical-autocollimator 32 is placed in
On autocollimator bearing 33.Afterwards, the control element of the magnetic base 41 of mobile terminal 4 is rotated and (eliminate magnetic to " OFF " state
Power), after its end face is fitted tightly with the A face of guide rail matrix and B face respectively, rotary control member (recovers magnetic to " ON " state
Power), magnetic base 41 passes through magnetic attraction with guide rail 2, and can move along guide rail 2.When heat be not exclusively by pressing or
Other activation manners carry out operational control element and operate the regulation to realize magnetic force.Magnetic base 41 can have multiple gears, gradually
Become the magnetic that ground adjusts magnetic base.By speculum 45 and mirror mount 44 screw pretension.Adjust optical-autocollimator 32,
So that the parallel light tube of optical-autocollimator 32 and speculum 45 is aligned, then fasten the screw of pretension on speculum 45.
After optical-autocollimator 32 energising, see whether there are two cross hairs by its eyepiece.If not observing two
Cross hairs, needs to make mobile terminal 4 near fixing end 3, then adjusts height and the horizontal level of optical-autocollimator 32, make mesh
The center in the mirror visual field assumes two cross hairs.Far-end is shifted to along guide rail in mobile terminal 4, check two cross hairs whether still in
In the eyepiece visual field, and it is located at the center in the eyepiece visual field.If two cross hairs is superimposed completely, optical autocollimating is described
The light pipe of instrument 32 and speculum 45 are completely in same horizontal line.If two cross hairs is not superimposed, and position deviation is very
Greatly, then can be according to above-mentioned steps, left-right rotation speculum 45 or the horizontal level readjusting optical-autocollimator 32, directly
Be completely superposed to two cross hairs or make deviation therebetween in the range of measure error allows.Finally, pass through
Screw is fixing with autocollimator bearing 33 by optical-autocollimator 32.
In units of the length of bridge plate 42, mobile terminal 4 is moved away from the direction of fixing end 3, guide rail 2 is made
Mark, and reading from the eyepiece of optical-autocollimator 32, the data that record reads.Will rotation magnetic force base when moving every time
, to " OFF " state, during stopping, the control element of rotation magnetic force gauge stand is to " ON " state for 41 control element.During this,
Ensure that magnetic base 41 is fitted with the A face of guide rail and B face all the time.Mobile terminal 4 is mobile to be returned to the end of guide rail 2, according to
The length of bridge plate is that the mark of unit measures the linearity of each section of guide rail 2 again, until returning to fixing end 3 side.If twice
The reading observed in the same section of eyepiece in optical-autocollimator 32 of measurement guide rail differs 1～2 lattice, then illustrate measuring
Cheng Zhong, speculum 45 or optical-autocollimator 32 occur in that slight movement, need to measure again after recalibration is fixing.
The numerical value of round rereading record is averaged, you can with graphing method or calculating method or the professional linearity of input
Software for calculation tries to achieve deviation and figure.In addition, it is necessary to explanation, the magnetic absorption linearity measurer of the present invention is not only
Its linearity can be measured in guide rail 2 horizontal direction, its linearity can also be measured in guide rail 2 vertical direction.Only need by
Eyepiece rotates 90 ° to position as shown in Figure 4, and its measurement process is identical with said process, repeats no more.
Above various embodiments of the present invention are described in detail.It will be understood by those skilled in the art that can be not inclined
In the case of the scope of the invention (being limited by the accompanying claims), various modifications, change and change are carried out to embodiment
Change.To the explanation of right should from overall explain and meet the widest range consistent with explanation however it is not limited to example or
Enforcement example in detailed description.
