The present invention belongs to the field of photoelectric measurement technology, and aims at providing one kind of photoelectric encoder for measuring the planar tilt angle of no-rotation angle shaft. The technological scheme of the present invention includes reading system, shafting and casing. Coding disc and slit disc are mounted coaxially to the main shaft, the coding disc fixed to the main shaft rotates with the main shaft and the slit disc fixed with the casing via the reading system rack rotates with the casing. An LED mounted in the coding disc side and the receiving photodiode mounted in the slit disc side have aligned clear aperture. One balance weight is mounted onto the main shaft and always points vertically to earth core, and under the action of the balance weight, the main shaft together with the coding disc will not rotate, so that the casing with the slit disc has its angular displacement expressing the planar tilt angle of no-rotation angle shaft.
Description
One, technical field: the invention belongs to the photoelectric encoder that a kind of measurement that relates in the photoelectric measurement technical field does not have the flat inclination of corner axle.
Two, technical background: in scientific experiment, in machining or in some engineering construction, usually need to know or measure the angle that tilts between a plane that does not have a corner axle and the surface level, work again so that adjust or need obtain some useful data.For example, a scientific experimentation platform, before doing experiment, want level-off, if know the angle that test platform tilts in advance, how to adjust level and will select suitable way, perhaps just need test platform certain angle that will tilt in scientific experimentation, could carry out scientific experimentation, this just need measure the plane of test platform and the angle of inclination between the surface level.And for example, in machining, need to adjust the work top of lathe, could guarantee machining precision and quality, a universal grinding machine external is when the rounding conical surface, and the upper table face is with respect to the lower table face, be adjusted to position, certain pitch angle, just can start working, for the angle of bank measurement of upper table face with respect to the lower table face, just quite be the measurement to the flat inclination of no corner axle.In measuring equipment, can find the equipment that adopts the electromagnetic principle design to the plane camber angle of no corner axle.Because our invention is according to the photoelectric measurement principle design, therefore, we think the prior art the most approaching with the present invention, also should be the photoelectricity angle-measuring equipments that adopts the photoelectric measurement principle design.
As everyone knows, adopting the optical electric axial angle encoder of photoelectric measurement principle design is the representational photoelectric sensor of measured angular displacement, the optical electric axial angle encoder that Changchun Institute of Optics, Fine Mechanics and Physics, CAS develops, as shown in Figure 1, comprise frame of reference, axle system, housing, frame of reference comprises accepts photoelectric tube 1, frame of reference support 2, screw 3, slit plate 4, code-disc 5, luminotron 9; Axle system comprises main shaft 6, collar bush 7, bearing 8; Housing comprises flange 10, cylinder blanket 11.
This optical electric axial angle encoder is the axis of symmetry assembling with main shaft 6, code-disc 5 is fixed on the main shaft 6, rotate with main shaft 6, slit plate 4 and code-disc 5 opposing parallel, leaving certain interval installs, slit plate 4 relative main shafts 6 are motionless, when main shaft 6 drives code-disc 5 rotations, photic zone at code-disc 5 and slit plate 4, high level output is arranged, writing down the angular displacement that main shaft 6 rotates, because the main shaft coaxial cable of the axle of measured piece and scrambler rigidly fixes, therefore, the angular displacement of scrambler main shaft rotation is exactly the angular displacement that measured piece rotates.
This optical electric axial angle encoder is the angular displacement of measuring measured piece with the rotational displacement of main shaft.It not energy measurement do not have the flat inclination of corner axle, its housing is a cylinder blanket, is connected also very difficultly with the plane of no corner axle, tries every possible means also to be difficult to reach the purpose of the plane camber angle of measuring no corner axle.
Three, summary of the invention: for overcome the prior art optical electric axial angle encoder not energy measurement do not have the problem of the plane camber angle of corner axle, the objective of the invention is to adopt the photoelectric measurement principle, design a kind of new photoelectricity angle-measuring equipment, solve the plane camber angle problem of measuring no corner axle.
The technical problem to be solved in the present invention is: a kind of photoelectric encoder of measuring the plane camber angle of no corner axle is provided.The technical scheme of technical solution problem is as shown in Figures 2 and 3: comprise frame of reference, axle system, housing; Frame of reference comprises: receive photovalve 12, slit plate 13, code-disc pressure mother 16, code-disc packing ring 17, code-disc 19, luminotron 22, frame of reference support 24; Axle system comprises: bearing is pressed mother 14, bearing 15, screw 20, main shaft 21, main shaft counterweight 23; Housing comprises: square casing 18, screw 25, interface connecting hole 26.
