Description
Technical field
The present invention relates to the optical coordinate measuring apparatus device, is the inspection machine of workpiece in the production run, belongs to the detecting instrument technical field, is a kind of moving gantry type optical coordinate measuring instrument specifically.
Background technology
Coordinate measuring apparatus is mainly used to measure the physical dimension of testee, be particularly useful for measuring the physical dimension of irregularly shaped object, usually divide two dimension, three-dimensional coordinate measuring instrument, divide contact and contactless two classes again, the said optical coordinate measuring apparatus of the present invention belongs to three-dimensional coordinate, contactless.Optical coordinate measuring apparatus has been one of measurement of coordinates technology with fastest developing speed since nearest 15 years, and along with the high speed development of digital vedio recording technology and computer software technology, the measuring accuracy of optical coordinate measuring apparatus is also more and more higher.Since its coordinate measuring apparatus with respect to routine have simple to operate, measure advantage fast, in production practices, be applied more and more, and progressively get and replaced conventional coordinate measuring apparatus.
The ultimate principle of optical coordinate measuring apparatus is: projection source is positioned at the testee below, the image of testee is projected on the sensitive surface of panadaptor, panadaptor changes the image that receives into the image of digital form again, by computer software to the identification of digital picture profile with calculate the physical size of trying to achieve testee.Therefore the optical coordinate measuring technology is the product that optical measuring technique and computer image processing technology are combined closely.Its key problem in technology is that the image that must guarantee testee correctly is projected on the panadaptor (undistorted), therefore, must guarantee gauge head or measured piece easy motion on X, Y and Z direction, simultaneously, transmitted light source must use burnt light path light source far away, and light source must be in the same optical axis with enlarging objective.In order to realize this purpose, present normally used method has following three kinds:
First kind is to adopt cantilever design, and in this structure, the Z axle of instrument is installed on the motionless cantilever.And scaffold tower is made X in surface level, and the motion on the Y direction is with the synchronism of the motion that guarantees transmitted light source and enlarging objective.But this class cantilever design is often thiner, and cantilever usually produces vibration during the scaffold tower motion, thereby influences the right alignment of light source, the measurement result that finally leads to errors.In large-scale optical measuring instrument, this class phenomenon is especially outstanding.
Second kind of structure is fixing planer type structure, and in this structure, the crossbeam that X axis is housed is fixed on the base by the two ends pillar, maintenance transfixion state.And scaffold tower is done the motion on the Y direction.The Z axle is done moving on the directions X along the guide rail of crossbeam.
More than two kinds of structures because the scope of scaffold tower motion must be double in the stroke of measurement range, therefore make type bigger than normal, weight is bigger than normal.
The third structure belongs to the travelling gantry structure, is usually used in the contact three-coordinates measuring machine, can reach the purpose that reduces volume and weight.In this structure, two gantry upright post and crossbeam all are positioned on the scaffold tower face, and wherein, an end column is installed on the guide rail, directly drives with drive motor, and another column and crossbeam are then dragged by this column passively.Therefore, except the system deviation of routine, instrument has also increased a torsional deflection on the X-Y plane that drives column.Because crossbeam adds the effect of the caused inertial force of deadweight of Z axle, whole frame has produced a torsional deflection on a Y-Z plane that drives the column guide rail again.Because constantly the position of movable Z axle constantly changes on crossbeam, and the centre of gravity place of whole frame is constantly changed, therefore, these two torsional deflection have randomness, are not easy very much to revise, and make this moving gantry type coordinate measuring apparatus precision low.In addition, this structure is not suitable for optical coordinate measuring apparatus because can't the fixed transmittance light source.
Summary of the invention
The objective of the invention is the deficiency that exists at prior art and a kind of moving gantry type optical coordinate measuring instrument is provided, guarantee that panadaptor and the relative motion of measured piece on X, Y and Z direction are steady, do not have and reverse, and the enlarging objective of light source and panadaptor is in the same optical axis.In addition, the moving-member stroke is little, makes that the instrument volume is little, measuring accuracy is high, working service is convenient.
