Abstract
One kind positioning aligner, it is characterized in that including frame, being arranged on the beam emissions unit along equally distributed more than three of surrounding in frame, the camera above the middle part of the circle impaled positioned at each beam emissions unit being arranged in frame, beam emissions unit includes the downward concave mirror of support, the concave surface being arranged on support, is arranged on the shadow shield of the light source of concave mirror focal point, the middle part being arranged on concave mirror underlying holder with thang-kng passage.The utility model compared with the prior art, with positioning alignment efficiency high, will not defective work piece or instrument advantage.
Description
Technical field
The utility model is related to a kind of e measurement technology.
Background technology
Digit Control Machine Tool（Including lathe, milling machine, vertical machining centre etc.）, the numerical control equipment such as industrial robot generally using
Need to set up workpiece coordinate before, the quality that workpiece coordinate is set up directly influences the machining accuracy to workpiece.Digit Control Machine Tool is built
Founding the common method of workpiece is：By cutter clamping on lathe, then the machine tool running is controlled to make the top slowly near workpiece of cutter,
When cutter soon with absorption surface when, it is necessary to slow down cutter close to the speed of workpiece, when cutter marks a sleek in workpiece surface
Mark then illustrates that the current location of cutter is the point position that we need to find, and workpiece surface finds two properly again in the same way
Point, then by relevant parameter input lathe can just set up corresponding workpiece coordinate.Industrial robot is operated to workpiece
Before need to set up tool coordinates, user coordinates etc., by taking the industrial robot for carrying vision as an example, robot needs before the use
Demarcated, it is general during demarcation to clamp a relatively fine workpiece in robot end, gone to contact scaling board with workpiece end
On circle center, obtaining the location of this central point, set up right by finding other two points again with same method
The user coordinates answered.These positioning alignment methods all have one disadvantage in that at present：Need to clamp an object in executing agency end
Go to be close to another object for needing to be aligned again, two objects are in contact the need for this alignment methods are inevitable, Er Qie
Fast being close to when being aligned object needs slow-down, is otherwise easy to and is aligned object collision；Not only efficiency is low for this method
Under, and be easy to make cutter and workpiece impaired.
Utility model content
Goal of the invention of the present utility model is to provide a kind of positioning alignment efficiency high, will not defective work piece or instrument
Optical alignment aligner.
The utility model be achieved in that including frame, be arranged in frame along equally distributed three of surrounding with
On beam emissions unit, the shooting above the middle part of the circle impaled positioned at each beam emissions unit being arranged in frame
Head, beam emissions unit includes the downward concave mirror of support, the concave surface being arranged on support, is arranged on the light of concave mirror focal point
The shadow shield of source, the middle part being arranged on concave mirror underlying holder with thang-kng passage.
During work：The light of the light source of beam emissions unit is by concave mirror into light vertically downward and logical through thang-kng
Road forms the light beam of minor diameter, and skew back simultaneously above intersects the downward light of each beam emissions unit on one point below inside, moves
Dynamic the utility model, as long as the crosspoint of light more than three beams is located on the current location of article, camera is just observed only
One reflective spot, so that the reflective spot on article and the distance between optical alignment aligner are just can determine that, and then it is right to complete positioning
It is accurate.
Here, frame by bar be formed by connecting in prism-frustum-shaped thing, the pedestal upper end of beam emissions unit is provided with perforation, wears
The side wall in hole is worn and is connected to screw rod, and wearing for support is on the corresponding side rod being connected on below prism-frustum-shaped thing frame and solid by screw rod
It is fixed.When using, by along perforation swinging mounting, can just adjust the angle of the downward light of beam emissions unit skew back inside, enter
And the position in the crosspoint of more than three beams light is adjusted, the attitude of beam emissions unit is consolidated by screw rod after regulation good position
It is fixed.
The utility model compared with the prior art, during due to positioning alignment, without needing light-seeking aligner and absorption surface,
And positioning alignment can be just only completed by observing formation of the crosspoint on workpiece, therefore, efficiency high is directed at positioning, no
The advantage of meeting defective work piece or instrument.

Specific embodiment
The utility model is described in further detail in conjunction with drawings and Examples：
As shown in Figure 1, 2, 3, the utility model include frame 8, be arranged in frame 8 equally distributed three along surrounding
Taking the photograph above beam emissions unit 6 above, the middle part of the circle impaled positioned at each beam emissions unit being arranged in frame 8
As head（It is fixed on the camera bracket 9 of frame 8）, as shown in FIG. 4,5,6, 7, beam emissions unit 6 includes upper end with company
The downward concave mirror 3 in the support 12 cylindrical in shape of joint a, the concave surface being fixed on the inner concave mirror pole 7 of support 12 cylindrical in shape,
It is fixed on the inner light source pole 11 of support 12 cylindrical in shape and the light source 4 positioned at the focal point of concave mirror 3, is fixed under concave mirror 3
Shadow shield 13 of the middle part with thang-kng passage 5 in side's support 12 cylindrical in shape.
The light of the light source 4 of beam emissions unit 6 is reflected into light vertically downward by concave mirror 3, and through the shape of thang-kng passage 5
Into the light beam of minor diameter, skew back simultaneously above intersects the downward light of each beam emissions unit on one point below inside.
As shown in Figure 1, 2, 3, frame 8 by bar be formed by connecting in prism-frustum-shaped thing, the upper end of support 12 of beam emissions unit 6
Connector a on be provided with perforation 1, the side wall of perforation 1 is worn and is connected to screw rod 2, and the perforation 1 on the connector a of the upper end of support 12 is worn
It is connected on the corresponding side rod 10 below prism-frustum-shaped thing frame 8 and is fixed by screw rod 2.When using, branch is rotated by along perforation 1
Frame 12, can just adjust the angle of the downward light of beam emissions unit 6 skew back inside, and then adjust the intersection of light more than three beams
The position of point, is fixed the attitude of beam emissions unit 6 by screw rod 2 after regulation good position.
