Abstract
In the three-coordinate measurement, flat plate with planeness and cube with high verticality are used as measurement reference; and after the measured body is fixed onto the cube and with the 3D rolling of the cube and the measured body, one 3D coordinate system is established. By means of 1D height measuring tool and planar shift, the 3D size and geometrical shape measurement is converted into the measurement of height and degree of parallelization. The present invention is one smart and simple measurement with high precision and low cost, and is suitable for especially for small factory, mechanical workshop and laboratory.
Description
One, technical field
The present invention relates to the measuring method and the measurement mechanism of Measuring Object three dimensions size and dimension, be specifically related to a kind of three-coordinate measuring method and measurement mechanism thereof.
Two, background technology
Accurate measurement means is to guarantee the essential condition of product quality in batch.Three dimensional coordinate measuring machine is the equipment that present function is maximum, precision is higher, because the non-general medium or small factory enterprise that costs an arm and a leg can purchase.Chinese patent 92112843.6 disclosed " simple three-eimensional measuring " is made up of parts such as the slip X slide plate on X, Y, Z shaft component, Y slide plate, Z slide plates; Chinese patent 92242005 disclosed " both arms separate type 3-dimensional marking and measuring machine " is made up of parts such as worktable, guide rail, slide plate, columns, and they all adopt skateboard, have shortcomings such as complex structure, accessory is many, use is limited.
Three, summary of the invention
The objective of the invention is to overcome and state deficiency on the prior art, a kind of simple in structure, low cost of manufacture is provided, measurement function is many, novel three-coordinate measuring method and device easy to use.Its technical scheme is as follows:
A kind of three-coordinate measuring method, the regular cube that utilizes the flat board of a high flatness and high verticality is as measuring basis, testee is fixed on the regular cube, testee rolls with regular cube three-dimensional on flat board, set up a mutually perpendicular coordinate-system of three-dimensional, survey under the cooperation that high measurer peace face moves at one dimension, the three-dimensional dimension of measurand and geometric configuration metering are become be one and survey high and measure the problem of the depth of parallelism.Described plane planeness is at least 0.001mm; Described regular cube verticality is at least 0.001mm.
The three-dimensional coordinates measurement device comprises workbench, altimeter, gauge head and slip gauge, has fixedly that the regular cube of testee places on the workbench, and a cubical plane is provided with the screw hole that is used for fixing testee; By altimeter, gauge head and slip gauge and to cubical Three dimensional rotation, the testee on the cube is measured.
The present invention adopts flat board, cube and one dimension length metering means combined, realizes the metering of object dimensional size and geometric accuracy.The function that possesses general length measuring tool, ruler, tool microscope and three coordinate measuring machine multi-section measurer and equipment.Compared with prior art have following major advantage:
1 compares with general length measurer, is increased to from one-dimensional measurement and three-dimensionally surveys long and ruler can directly be measured out of plumb pin-point accuracy data rather than estimation numerical value mutually.
2 compare with tool microscope, measure three-dimensional dimension and geometric configuration under the measurand one-step installation condition.
3 compare with three coordinate measuring machine, have characteristics simple in structure, easy to manufacture.
4, this device has exhausted most function of three coordinate measuring machine, and its measuring accuracy also reaches identical grade, is particularly suitable for medium-sized and small enterprises and the laboratory is selected for use.
It is low to use the present invention to remove speed, and outside energy measurement curve, space curved surface and the large-sized object, function is not identical with three coordinate measuring machine.
Three, description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present invention.
Five, embodiment
The present invention utilizes the regular cube of the flat board of a high flatness and high verticality as measuring basis, and measurand is fixed on the regular cube.Measurand is rolled with regular cube three-dimensional on flat board, set up a mutually perpendicular coordinate-system of three-dimensional, survey under the cooperation that high measurer peace face moves at one dimension, just can become the three-dimensional dimension of measurand and geometric configuration metering and be one and survey high and measure the problem of the depth of parallelism.Described plane planeness is 0.001mm; Described regular cube verticality is 0.001mm.
Referring to Fig. 1, the three-dimensional coordinates measurement device comprises workbench 1, altimeter 2 and slip gauge 3, has fixedly that the regular cube 4 of testee 5 places on the workbench 1, and near near the altimeter gauge head 6; Cube 4 is provided with the fixing threaded hole 7 that is used for fixing testee 5.Flat board 1 of this device and regular cube 4 all are to use natural granite to make through Precision Machining, made full use of the natural stone stable in properties, non-corrosive, wear-resisting, proportion is little than iron and steel, temperature-resistant characteristics have guaranteed this device constant characteristics of precision under long preservation and service condition.Use the present invention only to need testee is fixed on the cubical screw 7 by locator card and setscrew nut, gauge head by altimeter 2 and slip gauge 3 and to the Three dimensional rotation of cube 4 are measured the testee on the cube 45.
This device uses one dimension to survey high measurer and directly measures when hanging down precision measure; High-acruracy survey adopts and slip gauge measuring method relatively.
This device is because of simple in structure, low cost of manufacture, and measurement function is many, precision is high, and is easy to use, and is less demanding to operator's technical ability, and low price is particularly suitable for middle-size and small-size millwork job shop and laboratory and selects for use.This measurement device principle simply, intuitively has junior middle school's cultural knowledge, just can operate through short time study.
