Abstract
The utility model relates to an optical rotation device of the microhardness tester for the indentation, which consists of a shell, a step motor, a gear, a composite shaft housing group, a prism and a mirror reflector. The utility model is characterized in that: the motor is arranged in the shell, and provided with a pinion-gear at the output shaft end; the composite shaft housing group is positioned in the shell; the prism is fixed on a moving axis of the composite shaft housing group through a clamping bar and a bolt; a big gear is matched with and fixedly connected with a bearing cap of the composite shaft housing group; a middle gear is arranged between the big and the pinion gear; the mirror reflector is positioned at the side of the composite shaft housing group. The utility model, adopting the principles of electronic control and optical imaging, has the advantages of 90 degrees automatically rotating indentation, the realization of diagonal lines measuring without the rotation of the measuring eyepiece, and high accuracy.
Description
The utility model relates to microhardness testers, refers to make with Electronic Control and optical imagery the impression optics whirligig of the automatic half-twist of impression especially.
According to the principle of micro-vickers hardness, the test of metal material hardness is summed up as measurement to adamas impression catercorner length.Present used micro Vickers, after finishing a diagonal line linear measure longimetry, manually measuring eyepiece is rotated 90 °, again to the measurement of another catercorner length, operation was both time-consuming like this, brought artificial error again, influenced measuring accuracy, because when measuring at every turn, the slotted line that must adjust eyepiece is cornerwise parallel with impression.
The purpose of this utility model is: the impression optics whirligig that a kind of microhardness testers are provided, do not need manually to rotate measuring eyepiece, press the knob on the control panel, make 45 ° of prism rotations and optical imagery, can reach precision measurement the automatic half-twist of impression.
For reaching above-mentioned purpose, the impression optics whirligig of a kind of microhardness testers of the utility model, be installed in the measuring eyepiece back, form by housing, step motor, gear, combination axle sleeve group, prism and two reflective mirrors, be characterized in: a step motor is installed in the housing, and its output axle head is equipped with a pinion wheel; One combination axle sleeve group is installed on the housing, and on the moving axis of combination axle sleeve group, a gear wheel is affixed with the bearing cap coupling of combination axle sleeve group with pressing plate, screw retention for a prism; Between gear wheel and pinion wheel, neutral gear is housed, be connected with housing with support; Two reflective mirrors are contained in combined the side of shaft sleeve group.
The described combination axle sleeve of technique scheme group is made up of axle sleeve, moving axis, bearing seat, bearing cap and steel ball.Between bearing seat, bearing cap and moving axis, steel ball is housed, play the rolling bearing effect, when bearing cap is installed, can adjusts and eliminate the gap.
Superiority of the present utility model is: as long as press READ key on the guidance panel, CD-ROM drive motor makes 45 ° of prism rotations, and the applied optics principle the automatic half-twist of impression, need not rotated measuring eyepiece and just can finish diagonal line measurement, accuracy height.
Below in conjunction with accompanying drawing the utility model and structure, technical characterictic are described further.
Accompanying drawing is a section of structure of the present utility model.
Description of drawings:
