Described stay-supported photoelectric displacement transducer is characterized in that: the blade of described switching wheel is the black light-proof material.
Principle of the present utility model
By diameter is that 0.3 millimeter stainless steel wire is backguy, it one hang on the testee, another cephalic disc is on the cable quadrant of sensor.When testee produces displacement pulling steel wire, cable quadrant will be done corresponding both forward and reverse directions rotation.Make the displacement transmission undistorted in order to allow steel wire tighten, be coaxially arranged with the disc spring of certain rigidity with cable quadrant.Too quickly in order to prevent the backguy pulling, adopt the automatic slipping device of ratchet to protect gear set not damaged.When cable quadrant rotates a week, by the gear set speed change, will switch wheel rotate ten thousand change more than, the displacement of measuring like this is exaggerated, reliable operation not only, and improved measurement accuracy and resolution greatly.Diameter is about energy twist circle steel wire on 50 millimeters cable quadrants again, so the displacement range can reach more than 1 meter.The blade that switches wheel is the black light-proof material, in order to switch the light of two grooved photoelectric interrupters.When the blade of black forwards in the photoelectric interrupter groove, covered light, phototriode then is in cut-off state; Produce outside the groove when switching impeller blade, then infraredly accepted and make its conducting by phototriode.Two photoelectric interrupters are installed in the relevant position of switching wheel, so just can convert the mechanical signal of forward and reverse rotation to reversible digital signal.After this digital signal is handled through the displacement display, demonstrate the data and the direction of displacement.
Effect of the present utility model
Precision height of the present utility model, range are big, the linearity and good stability, environmental requirement is low, volume is little, in light weight.The utility model is applicable to fields such as civil construction, machining, equipment installation, science and techniques of defence, scientific experiment; Especially connect with computing machine, can improve the ability of automatic control greatly.

Embodiment
Referring to Fig. 1 ~ 7.A kind of stay-supported photoelectric displacement transducer, comprise backguy 1, cable quadrant 3, disc spring 5, ratchet 10, gear set 6, switch wheel 7, grooved photoelectric interrupter 8, casing 11 and base 12, casing 11 is fixed on the base 12, be wound with driving gear 9 coaxial being placed in the casing 11 of cable quadrant 3, disc spring 5 and the gear set 6 of backguy 1, its main shaft 4 two ends are movably placed on the relative wall of casing 11; Five follower gears of gear set 6 are meshing with each other from large to small respectively and are placed in the casing, the ratchet 10 that is meshed with driving gear 9 is the maximum follower gear of gear set 6, by five angles is that the switching wheel 7 that 72 blades of spending constitute is minimum follower gears, the grooved mouth of two groups of grooved photoelectric interrupters 8 is tangent with the wheel face that switches wheel 7, and the phase mutual edge distance of two groups of grooved photoelectric interrupters 8 is more than or equal to the blade face width that switches wheel 7 blade far-ends.
Cable quadrant 3 diameters are 50mm, and backguy 1 diameter is 0.3mm, and casing 11 positions of cable quadrant 3 correspondences have backguy hole 2.The blade that switches wheel 7 is the black light-proof material.
Pull wire head 1 is to be connected with hook on the testee, to transmit the displacement between testee.The effect of cable quadrant 3 is coiling backguy steel wires.With the positive and negative displacement that the backguy steel wire transmits, cable quadrant drive main shaft and the conversion of adjustment sensing through certain diameter make the displacement that shows with reality consistent.The effect of disc spring 5 is undistorted for the displacement transmission, and tightens the backguy steel wire.To switch wheel through the speed change of gear set 6 and rotate more than ten thousand commentaries on classics, and reach the displacement enlargement amount and improve resolution and precision.By the switching wheel 7 that lighttight five blades of black are formed, effect is the light that switches two grooved photoelectric interrupters 8.Grooved photoelectric interrupter 8 is installed by certain angle, when the switching impeller blade of black forwards in the photoelectric interrupter groove, has covered light, and phototriode then is in by state; Outside blade produced groove, then infrared light was accepted triode and is made its conducting by photosensitive, and the mechanical signal with forward and reverse rotation is converted to reversible digital signal like this.Ratchet 10 is automatic slipping devices, protects gear set not damaged.
The concrete use of stay-supported photoelectric displacement transducer:
1), sensor be fixed by bolts to relatively do not produce on the member of displacement, its backguy is consistent as far as possible with the testee sense of displacement, and on same axis.2), on testee, install or the stickup hook, so that be connected with the sensor backguy.
3), hand pinches the backguy joint and pulls out steel wire lightly from sensor backguy hole, hang on the hook of testee.Be the limit when red streak appears in the steel wire of pulling out, can not pull out again.Otherwise the measurement of displacement will produce error or damage sensor.If the steel wire of pulling out falls short of, can add the connection steel wire and connect.
4), the positive and negative displacement estimated according to testee determines the backguy length of pulling out from sensor, to guarantee that its displacement is in the range ability of sensor.If a testee forward increases displacement, the backguy joint of sensor is pulled out earlier about 2cm, be connected with the hook of testee again.Along with the increase backguy meeting of positive-displacement amount is constantly pulled out, Zui Da range is 0-2000mm like this; If testee only oppositely increases displacement, the backguy joint of sensor is pulled out 2000mm be connected with the hook of testee.Along with the increase of reverse displacement, the backguy meeting constantly bounces back, and maximum range is 0-2000mm like this; If the positive and negative displacement of testee and sense of displacement precedence are unknown or changeable, the backguy joint can be pulled out 1050mm, guarantee that like this its range is-1000-1000mm.Known to last, the user can be by displacement and the sense of displacement precedence estimated, and the length of can any free backguy joint pulling out is to reach best measurement effect.
