Technical field
The present invention relates to a kind of pick-up unit mainly for detection of displacement transducer error.
Background technology
Displacement transducer is also called linear transducer, and be a kind of linear unit belonging to metal induction, the effect of sensor is that various measurand is converted to electricity.Displacement is the amount relevant with the movement of the position of object in motion process, and the scope involved by the metering system of displacement is quite widely.Thin tail sheep detects with strain-type, inductance type, differential transformer type, eddy current type, Hall element usually, and large displacement is commonly used the sensing technologies such as inductosyn, grating, appearance grid, magnetic grid and measured.Wherein grating sensor because of have easily realize digitizing, precision high (the reached nanoscale that current resolution is the highest), antijamming capability strong, do not have artificial reading error, easy for installation, use the advantages such as reliable, in the industry such as machine tooling, measuring instrument, obtain increasingly extensive application.Current displacement transducer error-detecting still adopts slide block draw ring hook mode to carry out error-detecting, the weak point of this error-detecting is: due to different products, mounting means is different, measuring accuracy is different with scope, and this error-detecting can cause often produces a kind of displacement transducer, just needs configuration corresponding checkout equipment, this not only greatly increases cost and drops into, and this kind equipment footprints is large, very heavy, be unfavorable for very much carrying out of erecting yard debugging efforts.Next is that slide block is connected with sensor for being flexible coupling, and zero-bit is difficult to accurately judge and adjustment, and particularly connected mode is the displacement transducer of bayonet type, and existing error detecting apparatus is inapplicable.In addition, this more old-fashioned error-detecting slide rail, manufacturing process is complicated, and the time grow, sliding mode instability, can not fine adjustment displacement, causes read untrue.How can detect by compatible all types of displacement transducer, thus reduce manufacturing cost, and energy accurate adjustment, adjustment zero-bit and displacement scale fast, reliability is higher, becomes the problem that the error-detecting of present bit displacement sensor is anxious to be resolved.
Summary of the invention
The object of the invention is the weak point existed for above-mentioned prior art, provide a kind of precision accurately and reliably, highly versatile, detection efficiency are high, can realize the detection of compatible all types of displacement transducer, and the pick-up unit of the quick accurate adjustment of energy.
The technical solution adopted for the present invention to solve the technical problems is: a kind of displacement transducer error versatility pick-up unit, comprise the support of set-up scale and regulate displacement transducer to be measured laterally, the direction regulator of length travel amount, it is characterized in that: be shaped with the line slideway 1 of set-up scale 2 and the displacement transducer to be measured 7 be fixed on support 6 one end mounting plane plate 12 and stay cord connector 8 thereof on the frame 6, the slide block 4 along the movement of described line slideway 1 is provided with below described scale 2, be provided with on the slide block 4 of tuning drive gear at this, be fixedly connected with the jockey 3 of parallel staff 2, this jockey 3 termination is provided with the stay cord connector that can rotate around positioning screw rod axle center, and coaxially connect positioning screw rod 5 by the handle cylinder connected firmly on slide block 4, central axis is positioned on the line of stay cord connector 8.
The present invention has following beneficial effect compared to prior art:
Precision is accurate.The present invention is by being arranged on the tuning drive gear of slide block 4, according to the stay cord export center position of different model displacement transducer, adjusting slider level longitudinal direction and vertical height direction regulator, can the concentricity of the sensing range of compatible all types of displacement transducer and the stay cord export center position of all types of displacement transducer and jockey, ensure that the concentricity that jockey on stay cord export center position and positioning screw rod is good, accuracy of reading, ensure that the accuracy checking precision, reliability is higher than prior art.The error-detecting of reliable completion bit displacement sensor.
Detection efficiency is high.The present invention adopts hard connecting mode between positioning screw rod and jockey, and the connection of stay cord and positioning screw rod is reliable.By jockey and stay cord connector or bayonet socket is spacing is connected, facilitate and regulate positioning screw rod docked by jockey and stay cord connector and be reliably connected, moved by the tuning drive gear on positioning screw rod adjusting slider, alignment scale " 0 " scale is fast, can realize fast accurate adjustment, adjustment zero-bit.The unique texture that effective coupling part of jockey and stay cord connector can rotate around positioning screw rod axle center, by any rotation adjustment of positioning screw rod, be convenient to very much jockey and stay cord connector quick, reliably dock.Positioning screw rod and jockey, jockey and stay cord connector, all adopt Hard link or the spacing connected mode of bayonet socket between three, can realize adjusting quickly and accurately, zero-bit of harmonizing.
Highly versatile.The present invention can according to existing displacement transducer or Future Development trend, the line slide rail of customization suitable length, and its length can install the scale being greater than the existing or presumable maximum displacement value of product, and scale specification is 0.5mm.And according to the installation dimension requirement of different model displacement transducer, and the stay cord connected mode of different model displacement transducer, change corresponding mounting plane plate and jockey, all types of displacement transducer stay cord can be realized and be connected with the reliable of positioning screw rod.Wherein, the jockey that can rotate around positioning screw rod axle center is connected with the effective of stay cord connector, by being provided with the slide block 4 along the movement of described line slideway 1 below chi 2, realizes a hardware compatibility to the error-detecting of all types of displacement transducer.By changing corresponding special stay cord connector, realize the installation of an all types of displacement transducer of hardware compatibility.
