Abstract
The utility model belongs to a detecting instrument which uses the laser collimation technology in the engineering measurement. The detector comprises a laser, an optical collimation system with a collimation telescope with laser having a light spot diameter of 3-7 mm in a measurement range of 0-60 m, a receiving device of a portable photoelectric measuring ruler with a two-image silicon photocell gauge outfit and a digital display vernier caliper, and the like. The method has the advantages of low cost, high detection precision, convenient field actual measurement, capability of measuring at a medium distance (less than 60 meters) and the like. The method can be widely used for detecting machined parts and large components.
Description
The utility model belongs to the detecting instrument that uses with laser collimation technology in engineering survey.
Existing laser alignment detector has and involves great expense, and the field measurement inconvenience is difficult to shortcomings such as popularization.
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of cost low, and field measurement is convenient, measuring accuracy height, and the laser alignment detector of energy measurement moderate distance (less than 60 meters).
The utility model is introduced pick-up unit to laser collimation technology and optical detection principle, with the beam center line is datum line, by collimation compression laser beam divergent angle, make hot spot in measuring distance, keep 3～7 millimeters, utilize photoelectricity transformation principle again, establish the spot center line, last distance of directly reading spot center and tested point by digital display vernier card, each measuring point is detected value to the difference of spot center distance.
The utility model is made up of by known connecting mode laser instrument, optical alignment system, receiving trap.In the optical alignment system, adopted and to have guaranteed that laser has the collimating telescope of 3～7 millimeters spot diameters in 0～60 meter measurement range.In receiving trap, adopted two to resemble the portable light electrical measurement chi that silicon photocell gauge outfit and electronic digital indicator are formed.Two resemble the silicon photocell gauge outfit places silicon photocell cone 5, and the common tackifier of silicon photocell cone 5 usefulness is solid at vernier scale on one's body on 7.
Accompanying drawing 1 is the utility model synoptic diagram.Sequence number 1 is a laser instrument among the figure, and 2 are the optical alignment system, and 3 is receiving trap.
Accompanying drawing 2 is surveyed the chi structural representation for photoelectricity.Sequence number 4 is the iron seat among the figure, and 5 is the silicon photocell cone, and 6 is DC microammeter, and 7 is blade, and 8 is vernier, and 9 is gib screw, and 10 is the digital display window.
Accompanying drawing 3 is two to resemble photoelectric cell display device synoptic diagram.
The utility model is described in further detail below in conjunction with accompanying drawing: this detector is selected the HJ1BHe-Ne laser instrument of being produced by Nanjing laser instrument factory for use.This laser instrument is exported apparent 6328 ° of A ruddiness, 230 millimeters of laser pipe ranges, power 1-3 milliwatt.Laser beam is 6.85 collimating telescope by the enlargement factor that is adopted in the optical alignment system, guarantee that laser has 3～7 millimeters spot diameters and sets up datum line in 0～60 meter measurement range, at last by receiving trap, this device has adopted by two and has resembled the portable light electrical measurement chi that silicon photocell gauge outfit and electronic digital indicator are formed.After photoelectric receiving arrangement receives, provide measurement data and reach testing goal.
During measurement, will be close on to be measured, guarantee that the chi face is vertical with datum line with the iron seat 4 that vernier 8 is fixed together.Adjusting vernier 8 allows laser inject display device, meter pointer just demonstrates the marginal deviation of beam center and center, the silicon photocell two halves left and right sides, it is zero that fine setting survey chi vernier 8 makes DC microammeter 6 meter pointers, read corresponding data by electronic digital indicator reading window 10 then, can obtain the deviate of survey face by each measuring point measured value by known method, reach testing goal to the Basis of Laser line.
Adopt this detector to detect overhead travelling crane camber and elevator rail linearity, its precision is 0.02 millimeter; The linearity of machines workpiece and large-scale component, levelness, verticality, its precision are 0.02 millimeter.
The utility model compared with prior art has that cost is low, accuracy of detection is high, field measurement is convenient, and energy In advantages such as moderate distance (less than 60 meters) measurements. Can be widely used in the detection of machined piece and large-scale component.
