Description
Technical field
The present invention relates to optical coordinate measuring technical fields, more specifically to a kind of optical coordinate measuring system
Positioning tool.
Background technique
When being measured using optical coordinate measuring system to sample, sample is placed on objective table first, and is made
The first side and second side of sample respectively with X-axis and Y-axis general parallel orientation.X-axis driving wheel is driven later, makes objective table in X
It is moved in axis direction.If it is observed that first side is deviateed relative to X-axis, i.e., first side has occurred relative to X-axis along Y
The displacement of axis direction, then illustrate the first side of sample and the depth of parallelism of X-axis, it is unqualified with the verticality of Y-axis.So
It needs to rotate sample, so that the first side of sample is parallel with X-axis, keeps the second side of sample parallel with Y-axis.But it rotates
Rotational angle when sample is not easy control, and operating personnel needs repeatedly the angle of adjusting sample, low so as to cause measurement efficiency.
Therefore, how sample is quickly located, to reduce manual labor amount, improves measurement efficiency, be art technology
Personnel's critical problem urgently to be resolved.
Summary of the invention

Specific embodiment
The invention discloses a kind of positioning tools, are specifically applied to optical coordinate measuring system, which can be real
Now to the quick positioning of sample.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Base
In the embodiment of the present invention, those of ordinary skill in the art without making creative work it is obtained it is all its
Its embodiment, shall fall within the protection scope of the present invention.
In a specific embodiment of the invention, the positioning tool of optical coordinate measuring system includes: positioning screw 3, adjusts
Axis 1, vertical axis 2, the first adjusting nut 41, the second adjusting nut 42, third adjusting nut 43 and the 4th adjusting nut 44.
Wherein, the both ends of adjustment axis 1 are equipped with positioning screw 3.First adjusting nut 41 and the rotation of the second adjusting nut 42
It is screwed on a positioning screw 3.First adjusting nut 41 and the second adjusting nut 42 lock adjustment axis 1 from the two sides of adjustment axis 1
Tightly on positioning screw 3.Third adjusting nut 43 and the 4th adjusting nut 44 are screwed on another positioning screw 3.Third tune
Adjustment axis 1 is locked on positioning screw 3 by section nut 43 and the 4th adjusting nut 44 from the two sides of adjustment axis 1.It is adjusted at four
In nut, the first adjusting nut 41 and the pairs of linea angulata of third adjusting nut 43 arrangement.Second adjusting nut 42 and the 4th adjusts spiral shell
The pairs of linea angulata arrangement of mother 44.Vertical axis 2 is connect with adjustment axis 1, and the two is mutually perpendicular to.
Before being positioned to sample, positioning tool is placed on objective table first, and makes adjustment axis 1 and vertical axis
2, respectively with Y-axis and X-axis general parallel orientation, move objective table along X-direction later, if it is observed that vertical axis 2 deviates X-axis,
I.e. displacement along the y axis has occurred relative to X-axis in vertical axis 2, then illustrating the depth of parallelism of vertical axis 2 Yu X-axis, and adjusts
Axis 1 and the depth of parallelism of Y-axis are undesirable.It will so be made by screwing the first adjusting nut 41 and third adjusting nut 43
Adjustment axis 1 rotates certain angle in one direction, or by screwing the second adjusting nut 42 and the 4th adjusting nut 44, makes
Adjustment axis 1 turns an angle to another way, the position to be seen that will not occur to vertical axis 2 relative to X-axis along the y axis
When shifting, illustrate that the depth of parallelism of vertical axis 2 and X-axis and adjustment axis 1 and the depth of parallelism of Y-axis are met the requirements.
Please refer to attached drawing 4, after objective table moves along the x axis, the first situation is: vertical axis 2 occurs relative to X-axis
Along the displacement of Y-axis forward direction, then the second adjusting nut 42 and the 4th adjusting nut 44 will be screwed, to make 1 edge of adjustment axis
It rotates in an anti-clockwise direction, the vertical axis 2 observed finally is made displacement along the y axis will not to occur relative to X again.Second
Situation is: the displacement along Y-axis negative sense has occurred relative to X-axis in vertical axis 2, then the first adjusting nut 41 and third will be screwed
Adjusting nut 43 finally makes the vertical axis 2 observed will not be again relative to X so that adjustment axis 1 be made to be rotated in the clockwise direction
Displacement along the y axis occurs.
In addition, the movement of objective table generation along the y axis can also be made after it will position tool and be placed on objective table,
Whether observation adjustment axis 1 can occur displacement along the x axis relative to Y-axis later.Its Principles of Regulation and above-mentioned Principles of Regulation
Identical, therefore, this article will not repeat them here.
In the present embodiment, by screwing the first adjusting nut 41 and third adjusting nut 43, or the second adjusting is screwed
Nut 42 and third adjusting nut 43, to adjust the angle of adjustment axis 1.Manual adjustment in compared to the prior art, the present invention
In adjusting angle be easy to control, and degree of regulation is high, can rapidly adjust in place adjustment axis 1 and vertical axis 2, finally will
Sample is placed on objective table, and two sides of sample is made to be bonded adjustment axis 1 and vertical axis 2 respectively.In the present embodiment
Positioning tool can be realized the quick positioning to sample.
Further, the hole of adjustment axis 1 and the cooperation of positioning screw 3 is limited as strip hole 11, and the strip hole 11 is along tune
The length direction of nodal axisn 1 extends, then positioning screw 3 can be located at position different in strip hole 11.It so can basis
It is specific to require to arrange two positioning screws 3.
Further, the one end of strip hole 11 far from 1 middle part of adjustment axis is limited as open architecture.Strip hole 11 in other words
One end far from 1 middle part of adjustment axis extends to the end of adjustment axis 1, and is formed and be open in the end of adjustment axis 1.It is installing
When adjustment axis 1, positioning screw 3 can be directly set to enter in strip hole 11 from the opening of adjustment axis 1.In disassembly adjustment axis 1
When, positioning screw 3 can be made to be detached from adjustment axis 1 from the opening of adjustment axis 1.The setting of 1 upper opening of adjustment axis greatly simplifies
The assembly of adjustment axis 1.
Further, the first adjusting nut 41 and/or the second adjusting nut 42 and/or third adjusting nut 43 are limited,
And/or the 4th adjusting nut 44, it is provided with spring washer between the adjustment axis 1, to prevent screwing the first adjusting nut 41,
Or second adjusting nut 42 or third adjusting nut 43 or when four adjusting nuts 44, weigh adjustment axis 1 wounded.
Further, for the ease of the fixation of positioning screw 3, it is additionally arranged pedestal in one embodiment, makes to position spiral shell
Bar 3 is fixed on the base.
Further, pedestal includes pedestal 5 and support 6.Support 6 is arranged on pedestal 5.Hole is offered on support 6, is positioned
Screw rod 3 is threaded through in the hole.Locking nut 7 is screwed on positioning screw 3, and positioning screw 3 is locked on support 6.More into
One step, two are set by support 6.Two supports 6 are distributed in the two sides of adjustment axis 1.Two locking nuts 7 are by positioning screw
3 are locked on two supports 6, form firm locking to positioning screw 3.
It is possible to further which pedestal 5 is fixed on objective table by way of magnetic.
Further, pedestal 5 can also be locked on objective table by screw.It is provided on pedestal 5 and cooperates with screw
Screw hole 8.Further, limiting the screw hole 8 is waist-shaped hole, which extends along the direction of positioning screw 3.Root
According to the specific location of objective table upper screwed hole, to select for screw to be screwed in suitable position in waist-shaped hole.
