Description
Technical field
The utility model relates to a kind of linear movement pick-up on-line calibration fixture, particularly relates to the simple and easy fixture of a kind of linear movement pick-up on-line calibration, and the standard gauge block combination of it and the above grades such as 4 etc. and 4, for carrying out on-line calibration detection to linear movement pick-up.
Background technology
Along with improving constantly of industrial automatization, wherein linear movement pick-up is widely applied, and in order to make displacement transducer keep good working order, is more and more subject to the attention of enterprises and institutions for the calibration test problems of linear movement pick-up.What calibration detection line displacement transducer was used at present is digital frequency meter, laser interferometer, displacement transducer marking apparatus, demarcates frame, gauge block, also can use Raster Indicator Verification Instrument to detect and calibration, but will be through three steps while detection with these equipment Alignments: first: displacement transducer is disassembled from former automation equipment, when dismounting, want marker number, handle the problems such as signal wire well; Secondly: displacement transducer is installed on checkout equipment and is calibrated, and sensor shows and generally in former automation equipment, shows; Again: displacement transducer is resetted and installed, and parameters, debug the displacement in former automation equipment, recovery completes.Calibration is carried out after detecting and all will dismantling, but in separate unit automation equipment, contains multiple displacement transducers in actual alignment detection, and Shan, automation equipment space is little, dismantlement work complexity, calibration also will be passed through positioning test is installed after detecting, consuming time longer, easily cause instrument failure, affect enterprise and produce.
There is use patent (displacement transducer on-line proving device) certain recent years, but this device project organization and size are bigger than normal, caliberating device standard displacement multi-purpose micrometer gauge carries out reading, low precision, uncertainty of measurement are excessive, the displacement transducer that is 0.1 μ m for resolution can not be calibrated, use in addition the checkout equipment volume such as laser interferometer, displacement transducer marking apparatus large, should not carry to Site Detection, giving us calibration personnel increases operational difficulties.
Summary of the invention
Fundamental purpose of the present utility model is to detect for solving linear movement pick-up energy on-line calibration, it is a kind of linear movement pick-up calibration clamp, fixture one end is fixed on displacement transducer measuring staff axle sleeve, the other end is adjustable working face, coordinate gauge block can carry out calibration testing, to solve the above-mentioned shortcoming in current calibration testing.
The utility model solves the technical scheme that its technical matters adopts: calibration clamp is symmetrical structure, two ends all adopt V-type workplace, two V-type workplace elongated surfaces overlap in theory, guarantee to measure on axis at one between two V-type workplace fixed objects, in the middle of V-type workplace, rectangular parallelepiped hole is set, is used for installing fastening kit, two V-type workplaces are fixed in cylinder connection bracket simultaneously, form calibration clamp, the fixing adjustable reference workplace of fastening kit for the V-type workplace of one end, other end V-type workplace is directly fixed on linear movement pick-up measuring staff axle sleeve with fastening kit, now can regulate adjustable reference workplace position according to the measuring staff of linear movement pick-up and probe location, make measuring staff gauge head contact suitable displacement with adjustable reference workplace center, adjustable reference workplace is made as to zero-bit, linear movement pick-up zero clearing, then coordinate the gauge block in 4 groups such as gauge block such as grade, divide 5 calibrations linear movement pick-up measurement range, such as measurement range is 15mm, choose so the 2mm having cleaned up, 5mm, 8mm, 10mm, 15mm gauge block is filled in respectively in the middle of adjustable reference workplace and measuring staff gauge head, read sensor indicating value respectively, pack up gauge block, finish writing calibration record, after calibration finishes, unclamp and be fixed on V-type workplace fastening kit on sensor measuring staff axle sleeve, take off calibration clamp, whole calibration process finishes.
The beneficial effects of the utility model are, can directly be fixed on sensor measuring staff axle sleeve the linear movement pick-up being arranged in automation equipment, make to calibrate detecting position displacement sensor without the calibration of dismounting direct-on-line; Volume is little, lightweight, and precision high (uncertainty of measurement is little) improves testing efficiency, reduces the equipment failure that calibration process human factor causes, and reduces testing cost.

Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and principle of work are made to specific description: fastening kit 1 is connected by connecting rod 11 with fastening kit spiral 4, in the time turning clockwise fastening kit spiral 4, fastening kit 1 will move down by connecting rod 11, fix the tested linear movement pick-up measuring staff axle sleeve 13 on V-type workplace 2 with this.
On V-type workplace 2, be hollow perpendicular to measuring fluted and V-type workplace metallic object 3 centers, the centre position of axis direction, groove location is placed fastening kit 1 just, V-type workplace metallic object 3 center hollow positions are through connecting rod 11, V-type workplace 2 provides the fixed datum of fixing tested linear movement pick-up, and the fastening kit 1 in intermediate groove is fixed strain effect.
V-type workplace 2 is on V-type workplace metallic object 3, the utility model agent structure is symmetrical, two ends V-type workplace 2,7, V-type workplace metallic object the 3, the 12nd, structure and size are identical, and two V-type workplaces 2,7 prolongation workplaces are same working faces.
Adjustable reference workplace right cylinder 6 can be fixed by fastening kit 8 shift positions on V-type workplace 7, reaches the object that regulates adjustable reference workplace 5.Specific works principle of the present utility model is such: when we carry out on-line calibration while detecting to being arranged on linear movement pick-up in automation equipment, find displacement transducer, determine the position of linear movement pick-up measuring staff axle sleeve 13, tested linear movement pick-up measuring staff axle sleeve 13 is inserted in the utility model fastening kit 1 from left to right, measuring staff axle sleeve is fully contacted with V-type workplace 2, screwing fastening kit spiral 4 is fixed on the utility model measured position displacement sensor, gauge head on sensor measuring staff 14 points to adjustable reference workplace 5 centers simultaneously, regulate the position of adjustable reference workplace right cylinder 6 according to probe location, after making adjustable reference workplace 5 contact gauge head, observe displacement transducer display, continue to regulate adjustable reference workplace 5 that linear movement pick-up gauge head is arrived in measurement range, with the fixing adjustable reference workplace right cylinder 6 of fastening kit spiral 10, the zero setting of measured position displacement sensor indicating value, then coordinate the gauge block 15 in 4 groups such as gauge block such as grade, divide 5 calibrations displacement sensor scope, such as measurement range is 15mm, choose so the 2mm having cleaned up, 5mm, 8mm, 10mm, 15mm gauge block 15 is filled in respectively in the middle of adjustable reference workplace 5 and tested linear movement pick-up gauge head, the read sensor error of indication respectively, finish writing calibration record, after finishing, calibration unscrews fastening kit spiral 4, take off calibration clamp, whole calibration process finishes.
