(3) utility model content:
The purpose of this utility model, be respectively overlap objective lens when a kind of workpiece of measuring the different brackets surfaceness will be provided can be according to the different needs automatic displacement, will different objective lens do not change change, convenient to operation, light-section microscope object lens conversion equipment that automaticity is high.
The utility model mainly constitutes by objective lens, Nosepiece with by the Nosepiece mechanism for automatically switching that V-shape base, crossbeam, rotating shaft, bearing, driving gear pair, stepper motor, register pin, attachment objective are formed.
Described objective lens and prior art are basic identical, different is: objective lens is three covers, being fitted in one is on the Nosepiece of being inverted bowl-type, be shaped on the mounting hole that matches with three cover objective lens on the sphere of this Nosepiece, every cover illumination objective lens and viewing objective symmetry screw in, and illumination objective lens of every suit and viewing objective are mutually 90 °, on the Nosepiece sphere, be shaped on and the corresponding register pin awl of the register pin of mechanism for automatically switching hole, Nosepiece is fixedlyed connected with the rotating shaft of mechanism for automatically switching with key by its sphere top endoporus, on this Nosepiece three cover objective lens has replaced the former quadruplet coversion objective of existing 9J type light-section microscope group, and total measurement range is constant, and the transposition of Nosepiece is realized by mechanism for automatically switching.
Described Nosepiece mechanism for automatically switching, its V-type seat, stepper motor, driving gear pair, bearing, rotating shaft all are packed on the crossbeam, Bearing Installation is on the rotating shaft axle journal, the central authorities that the V-type seat is passed in rotating shaft expose outside the V-type seat, fixedly connected with Nosepiece in its lower end, driving gear pair is made up of driving wheel and engaged wheel, driving wheel is connected with fastening bolt with step motor shaft, engaged wheel also is connected with fastening bolt with rotating shaft, register pin is arranged on attachment objective mounting hole next door on the V-type seat, with the register pin hole coupling on the Nosepiece spherical outside surface.
When checking the surfaceness of workpiece, workpiece is placed on the below of Nosepiece, if the multiplying power of cover object lens is improper, as long as click push button, the secondary rotation of stepper motor rotating band nutating gear, driving gear pair drives the rotating shaft rotation, and rotating shaft drives the Nosepiece rotation, and the centering of position just relies on corresponding register pin hole to cooperate with a pair of register pin on the V-shape base.Because the elastic pressure of register pin is not very big, during the Nosepiece rotation, register pin skids off from the register pin hole, fall in the hole again during to next register pin hole, at this moment stepper motor stops the rotation, Nosepiece has just changed new object lens multiplying power, so can carry out repeatedly, has just realized the automatic switchover of every cover object lens.
The utility model is compared with existing 9J type light-section microscope, and the one, swift to operate simple, when measuring the surfaceness of different brackets, need not change objective lens continually, as long as rotate the objective lens that Nosepiece just can be changed different multiplying; The 2nd, the rotation of Nosepiece realizes by mechanism for automatically switching, and is easy to operate, the automaticity height
