The laser detection guiding device
Technical field
The utility model relates to a kind of laser detection guiding device, belongs to coating checkout equipment technical field.
Background technology
Along with the develop rapidly of modern industry robotization, the various quality of fits of plant equipment are also more and more higher, and this accuracy requirement with regard to the effects on surface soverlay technique is more and more higher, therefore also with regard to the more accurate detection means of needs, its thickness controlled.When adopting sufacing that component surface is processed, if coating is too thin, may can not meet the requirement of component surface performance, do not reach the surface-treated purpose; If coating is too thick, not only cause the waste of material, also can cause the coating internal stress excessive, reduced the bond strength of coating, particularly to the surface treatment of parts mating surface, guarantee that size and new product element size after component surface is processed are consistent, the tolerance on fit when satisfying product design; If the coating became uneven also can produce harmful effect to the multiple mechanical and physical character of coating; Therefore, the detection of piece surface coating thickness seems particularly important.The mode of domestic main employing manual detection detects coat thickness at present, its work efficiency is low, artificial subjective judgement and error easily occur, and the error of perpendicularity between detected face and film thickness detecting instrument is larger, the precision of detection is relatively poor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of laser detection guiding device is provided, it can effectively guarantee the verticality between detected face and coating thickness measuring device, improved the accuracy that detects, improve production efficiency, had higher dirigibility and stronger production adaptative ability.
The purpose of this utility model is achieved in that a kind of laser detection guiding device, it comprises the six degree of freedom mechanical arm, described six degree of freedom robot end is provided with fixed support, be provided with film thickness detector and laser side on described fixed support apart from instrument, described laser range finder has three, and the plane of described film thickness detector and three laser range finder formations is perpendicular.
Described three laser range finders are uniformly distributed in around film thickness detector.
Compared with prior art, the utlity model has following beneficial effect:
A kind of laser detection guiding device of the utility model, it can effectively guarantee the verticality between detected face and coating thickness measuring device, improved the accuracy that detects, be conducive to improve efficient and the quality of coating preparation, reduce the waste of coating material, had higher dirigibility and stronger production adaptative ability.

Embodiment
Referring to Fig. 1 ~ Fig. 3, a kind of laser detection guiding device of the utility model, it comprises roller-way 1 and six degree of freedom mechanical arm 2, described six degree of freedom mechanical arm 2 is arranged at roller-way 1 one sides, described six degree of freedom mechanical arm 2 ends are provided with fixed support 3, be provided with film thickness detector 4 and laser side on described fixed support 3 apart from instrument 5, described laser range finder 5 has three, described three laser range finders 5 are uniformly distributed in around film thickness detector 4, and the plane of described film thickness detector 4 and three laser range finder 5 formations is perpendicular.
When detecting the workpiece thickness, three laser range finders 5 send laser measurement separately with the distance on measured workpiece surface, then with the internal control system of this data information transfer to six degree of freedom mechanical arm 2, the control system of six degree of freedom mechanical arm 2 is controlled the relative position that six degree of freedom mechanical arm 2 is adjusted itself and workpiece, make three laser range finders 5 identical with the distance on measured workpiece surface, namely three laser range finders 5 are parallel with the measured workpiece surface, thereby guarantee the verticality on film thickness measuring instrument 4 and measured workpiece surface.
