Generally speaking, can utilize flexible member list station tester to carry out the detection of precise corrugated pipe, but because current precise corrugated pipe range of application is more and more widely, the enhancing of production unit productive capacity, general tester can not satisfy the high-level efficiency requirement of production line.Multistation precise corrugated pipe tester has solved this contradiction, and multistation horizontal displacement test platform and automatic control test macro can satisfy the requirement of this respect, and the enhancing of production line detectability, efficient are improved.Simultaneously, this equipment also can carry out the online detection of other element (diaphragm, bellows, spring etc.).
Summary of the invention
The purpose of this utility model provides a kind of multistation precise corrugated pipe tester that corrugated tube is carried out the characterisitic parameter precision measurement.
The purpose of this utility model is achieved in that it includes base, column, motor, it is characterized in that: base is provided with the horizontal displacement test platform of band turn-screw, on the horizontal displacement test platform, be evenly equipped with the measured workpiece positioning seat, be connected with one in the bottom of horizontal displacement test platform by motor-driven turn-screw; Be provided with by another motor-driven gear train on the top of column, this gear train is connected with force cell downwards by driven shaft, is set with an afterburning testing pressure head at force cell pressurized position; Also be provided with a displacement transducer on the relative position on afterburning testing pressure head top, this displacement transducer is fixedlyed connected with main shaft by adjusting lever and connecting rod.
Above-mentioned force cell is connected with driven shaft by the frame that is rigidly connected.
Principle of work (as shown in Figure 3): by the computer control driver, drive stepper motor, control force application mechanism, horizontal displacement test platform respectively, tested precise corrugated pipe is positioned and loads.Gather the moving displacement signal with the photoelectricity length measurement system that force application mechanism is synchronized with the movement, and feed back to computing machine constantly.After compression displacement reaches setting value, the force application mechanism stop motion, the displacement signal of photoelectricity length measurement system collection and the test specimen of force measuring system collection bear the concentrated force signal, feed back to computing machine simultaneously, computing machine goes out the corresponding performance parameter of test specimen by computed in software, and storage is in order to printing and statistical study.This equipment has continuous coverage and two kinds of test modes of independent measurement.The continuous coverage function can realize many automatic continuous coverages of product, can satisfy the terminal online detection of production line; The independent measurement function can be carried out automatic independent measurement to single product, can be applicable to checking and detects and technical research.The user can select as required by man-machine interface.
Force application apparatus displacement by computer controlled automatic can reach 0.001mm, the accurate positioning of horizontal displacement test platform, and moving displacement can be controlled in 0.01mm, thereby can realize the test of one displacement of precise corrugated pipe concentrated force, concentrated force rigidity.Operation interface adopts the VB software programming in line with the principle of intuitive and convenient, and all operations only needs can finish by click, and nominal pressure value and nominal shift value all can be set arbitrarily in different range, also can carry out the measurement point of same measured piece and measure.When the production line end carried out continuous coverage, corresponding options can be finished many product performance parameter testings in the click menu; When independent measurement was carried out in checking detection and technical research, corresponding options can be carried out single product performance parameter testing in the click menu.Test raw data, family curve and result of calculation can be simultaneously displayed on the computer screen.Software also has functions such as data acquisition, data processing, error correction, curve fitting, deposit printing.
The utility model has the advantages that:
1. realized that micro-displacement moves control and high-acruracy survey, satisfied precise corrugated pipe and measure demand.
2. designed the multistation test suite, an equipment can satisfy the multiple precise corrugated pipe measurement of φ 2～φ 50mm, avoids producing the unbalanced defective of the application of force simultaneously, has improved measuring accuracy.
3. design the horizontal displacement test platform, can realize many product continuous and automatic testings, improved efficiency of measurement, be fit to the terminal online detection of production line.
4. the electronics localization method is taked in design, has optimized the displacement measurement system design, makes mechanical movement more reasonable.
5. report to the police and the program of protecting of trying hard to keep in the design room, guarantees the operation of test macro high efficient and reliable.
The utility model also has rational in infrastructure, easy and simple to handle, applied range, and this equipment also can carry out the online detection of other element (diaphragm, bellows, spring etc.), and long service life, steady performance.
