Abstract
The utility model relates to an optical coded shift sensor, which belongs to the field of shift sensors, comprising a housing, a body and a scale, wherein, the scale is engraved with light-passing slots with equal distance; the side of the body is punched with two light-passing holes; one side of each light-passing hole is provided with an infrared luminous tube, while the other side of each light-passing hole is provided with an infrared photoelectric tube. When the scale moves up and down, light coding can be generated. A plurality of scales can be interconnected and move in the hollow of the body. The utility model has the advantages of wide measuring range, high precision, good reliability, shock resistance, vibration resistance, simple structure and convenient operation. The utility model can be widely used for measuring shift, speed, acceleration, etc.
Description
The utility model belongs to the displacement transducer field.
At present, displacement transducer is of a great variety both at home and abroad, and comprising piezoelectric ceramics displacement transducer, magnetic induction displacement transducer, light transmitting fiber displacement transducer etc., each is different for their technical conditions and use occasion.In high-intensity magnetic field, the displacement transducer of the mechanical motion test of can satisfy that acceleration is big, impulsive force is strong, stroke is long seldom, generally speaking, the light coding displacement sensor relatively is fit to above-mentioned condition.Present light code sensor is because there are many problems in reasons in structure, and low as measuring accuracy, volume is big, and is not easy to operate, fragile, and shock resistance, anti-vibration performance are poor.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of shock resistance, anti-vibration and precision height are provided, easy to use, non-damageable smooth coding displacement sensor.
The utility model is made up of overcoat, main body, rule.Rule is a pole, at its top car bolt is arranged, and at its lower end car inner nut is arranged, and every rule can be interconnected, thereby increases measurement range; (except the bolt part) is carved with several equidistant light tanks on rule.Main body is the right cylinder of a hollow, vertically squeezes into two light holes that differ the certain level distance respectively in its side, and this two light hole is a through hole; Simultaneously, in light hole one side the infraluminescence pipe is installed, as optical transmitting set, opposite side is installed infrared photocell, as optical receiver.Rule is installed in the hollow of main body, entangles main body by overcoat then.When rule moves up and down in the main body hollow, can produce relative position light light and shade alternately, thereby produce the light coding, when rule whenever moves between one two light hole horizontal range, light coding changes once, and horizontal range has determined the measuring accuracy of its sensor between two light holes.
Description of drawings of the present utility model is as follows:
Fig. 1 is the utility model structural drawing.
Fig. 2 is the structural drawing of the utility model main body (2).
Fig. 3 is the A-A view of the utility model main body (2).
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model structural drawing; Fig. 2 is the utility model main structure chart.The utility model is made up of overcoat 1, main body 2, rule 3.Rule 3 upper end cars have bolt 4, and the lower end car has inner nut 5, and purpose is for several rules can interconnect, and enlarge measurement range.Rule 3 is a cylindrical bar, is carved with several equidistant light tanks 6 on it.Main body 2 is hollow right cylinders, squeezes into two light holes 7,8 in its side, and light hole 7,8 is a through hole, and light hole 7 is L with light hole 8 horizontal ranges; Side at light hole 7,8 is installed the infraluminescence pipe, as optical transmitting set; Opposite side is installed infrared photocell, as optical receiver.Rule 3 is installed in the hollow of main body 2, and overcoat 1 entangles main body 2.When rule 3 moved up and down in main body 2 hollows, the light and shade that just can produce the light of relative position replaced, thereby produced the light coding, when rule 3 whenever moves 7,8 horizontal range L of a light hole, the light coding changes once, therefore, and the horizontal range L determining measuring accuracy that light hole is 7,8.Material of the present utility model can must guarantee during manufacturing that the size of main body 2 hollows and rule 3 external diameters are consistent with steel or brass.
The utility model has the advantages that:
1, measurement category is big, the precision height, and reliability is strong.
2, shock resistance, vibration resistance, long service life.
3, simple in structure, easy to use.
Claims (2)
