Abstract
The indenting optical turntable for microscopic hardness meter consists of casing, stepped motor, gear, combined axle sleeve set, prism and reflector. It features that inside the casing there are one motor having output shaft with small gear at the end; one combined axle sleeve set having one clip and screw fixed prism on the moving shaft and one large gear matched with its bearing cap; one intermediate gear between the small and the large gears; and one reflector beside the combined axle sleeve set. By applying electronic control and optical imaging, the indenting is made to turn by 90 deg to accomplish diagonal measurement in high accuracy without rotating eyepiece.
Description
The present invention relates to microhardness testers, refer to make the impression optics whirligig of the automatic half-twist of impression especially with Electronic Control and optical imagery.
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 objective of the invention is to: a kind of impression optics whirligig of microhardness testers is provided, does 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 present invention, 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 invention 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 present invention and structure, technical characterictic are described further.
Accompanying drawing is a section of structure of the present invention.
Description of drawings:
The 1-step motor; The 2-pinion wheel; The 3-neutral gear;
The 4-gear wheel; 5-combination axle sleeve group; The 51-axle sleeve;
The 52-moving axis; The 53-bearing seat; The 54-bearing cap;
The 55-steel ball; The 6-prism; 7-reflective mirror (one);
8-reflective mirror (two); The 9-housing.
Embodiment: see also section of structure of the present invention, a kind of impression optics whirligig of microhardness testers, form by housing 9, step motor 1, pinion wheel 2, neutral gear 3, gear wheel 4, combination axle sleeve group 5, prism 6 and two reflective mirrors 7,8, be characterized in: a step motor 1 is installed in the housing 9, its output axle head is equipped with a pinion wheel 2, one combination axle sleeve group 5 is installed on the housing 9, one prism, 6 usefulness pressing plates, screw retention are on the moving axis 52 of combination axle sleeve group 5, and a gear wheel 4 is affixed with bearing cap 54 couplings of combination axle sleeve group 5; Between gear wheel 4 and pinion wheel 2, neutral gear 3 is housed, be fixed on (not shown) on the support, reflective mirror () 7 and reflective mirror (two) 8 are contained in combination axle sleeve group 5 sides, as shown in drawings.
Described combination axle sleeve group 5 is made up of axle sleeve 51, moving axis 52, bearing seat 53, bearing cap 54 and steel ball 55.Between bearing seat 53, bearing cap 54 and moving axis 52, steel ball 55 is housed, play the rolling bearing effect, when bearing cap 54 is installed, can adjusts and eliminate the gap.
