Abstract
The utility model adopts a special optical path system which is characterized in that a laser light source, a color filter, a small hole, a convex lens, a cylindrical mirror and a convex lens are arranged in a cassette from top to bottom. The processing of filtering color of the light source is conducted by the small hole and the colour filter device, and then the lens is used for focusing. Next, the point light source is stretched to a smoothing tool by the cylindrical mirror, and finally the lens is used for secondary focusing. The laser light smoothing tool with high luminance can be obtained. The laser light smoothing tool is used for scanning and measuring the configuration of an object, manual participation quantity is reduced, work efficiency is enhanced, and simultaneously the complete data of the surface of the object to be measured can be easily obtained.
Description
The utility model is to the anti-measuring equipment of asking of the three-dimensional surface of testee, is the improvement to existing measuring machine.
At present, modal measuring equipment is mechanical three-coordinates measuring machine, because it adopts the pointwise contact measurement, artificial participation amount is big when causing measuring, speed slow, the data imperfection.And the laser spots scanner is to adopt laser noncontact point-to-point measurement, still exists measuring speed slow, the incomplete shortcoming of data.People are expecting high efficiency, and the data integrity accurate technique scheme that obtains the testee surface produces as early as possible.
The utility model is to realize reducing artificial participation amount, increasing work efficiency, and the data integrity of acquisition measured object surface is purpose accurately.
In order to achieve the above object, the utility model comprises optical system, it is characterized in that: the optical system formation is: be provided with laser lamp source, color filter, aperture, convex lens, cylindrical mirror and convex lens in the magazine from top to bottom.
Optical system and videotape plate and be rigidly fixed on the fixed mount.
Adopt two plates that videotape, they are fixed on both sides, fixed mount top.
The utlity model has following advantage and good effect: 1, adopted special light path system, at first adopted aperture to add the color filter device, the light source look that filters is handled, used lens focus then; Secondly, adopt cylindrical mirror to realize pointolite is stretched as finishing tool, use the lens secondary focusing at last, obtain the high brightness laser finishing tool.Adopt laser light knife to come scanning survey object profile, significantly reduced artificial participation amount, improved work efficiency, be easy to obtain the partial data on measured object surface simultaneously.2, adopt two plates that videotape to adopt and resemble, improved measuring accuracy.3, optical system rigidly fixes with pickup system and is in the same place, and reduces vibration influence, has improved measuring accuracy.
Fig. 1 is the system block diagram of the utility model measuring machine;
Fig. 2 is the utility model optical system configuration composition.
1, laser lamp source; 2, color filter; 3, aperture; 4, convex lens; 5, cylindrical mirror; 6, convex lens; 7, magazine; 8, videotape plate; 9, testee; 10, fixed mount; 11, axle; 12, optical system.
Referring to Fig. 2, in order to realize laser line scanning, set gradually laser lamp source 1 in the magazine 7 from top to bottom, color filter 2, convex lens 4, cylindrical mirror 5 and convex lens 6.Two videotape plate 8 and are arranged on both sides, fixed mount 10 top.In order to reduce vibration influence, optical system 12 and videotape plate 8 and be rigidly fixed on the fixed mount 10.When testee 11 is measured, at first adopt aperture 3 to add color filter 2 devices, the colour filter that filters is handled to light source 1, and focus on convex lens 4, then, adopt cylindrical mirror 5 to realize pointolite is stretched as finishing tool, adopt the convex lens secondary focusing at last, obtain high brightness laser finishing tool (40mm).Said structure has guaranteed to come scanning survey object profile with laser rays, has significantly reduced artificial participation amount, has improved work efficiency, is easy to obtain the partial data on testee surface simultaneously.
Referring to Fig. 1, the utility model is made up of computer control system, digital control system, optical system and data processing and three-dimension curved surface reconstruct four parts.Wherein,
A, computer control system coordinated operation;
B, high-accuracy digital control system are that the machinery of measuring process is realized part;
C, optical system produce high precision, the big depth of field (40mm) laser light knife, and the testee surface is measured, and the gained data store in a cloud mode;
D, data processing and surface reconstruction are handled reconstruct to institute's invocation point cloud, obtain the required STL formatted file of curved surface data, CAD entity and quick type of standard format.
