Description
Technical field
The utility model belongs to the metallic bellows detection range, specifically relates to a kind of metallic bellows antifatigue examination pick-up unit.
Background technology
China discloses the laborsaving fatigue test device of a kind of metallic bellows CN201600295U number, and its background technology part has been done simple description to the attribute of metallic bellows and the basic structure of current corrugated tube fatigue tester.Known, the corrugated tube fatigue tester comprises a pair of anchor clamps that are used for clamping corrugated tube two ends, a clamps setting, and another anchor clamps can axially be driven along corrugated tube by drive unit, realize that the compression/stretching of corrugated tube is done.
The fatigue behaviour that known corrugated tube fatigue tester is used for large-scale corrugated tube more detects, the corrugated tube of using like the rocket internal weapon bays.For less corrugated tube, less than the 100mm corrugated tube, fatigue lifetime is longer like caliber, and large-scale experimental facilities is difficult to the laboratory facilities that provide frequency higher.And existing corrugated tube fatigue tester does not generally have the counting assembly of the tired stretching/compression test number of times of corrugated tube.
Need to prove; Current corrugated tube fatigue tester realize to-and-fro movement with the more employing of the drive unit of coupling compression/extensional motion slider-crank mechanism; This mechanism has effect preferably in the corrugated tube experiment of single model; But because its stroke is adjusted cumbersomely, applicability receives very big restriction.
Summary of the invention
The utility model is directed against the defective that present corrugated tube testing machine can not provide effective counting, and a kind of corrugated tube torture test apparatus test device that effective counting can be provided is provided.
The technical scheme that the utility model adopts is:
A kind of corrugated tube torture test apparatus test device; Comprise the corrugated pipe clamp that is used for spacer dimple pipe two ends; Drive an end corrugated pipe clamp and to corrugated tube at the drive unit that radially moves reciprocatingly, also comprise the harvester of gathering said drive unit to-and-fro movement number of times, input connects the control device and the display device that is used to show the to-and-fro movement number of times of this harvester; Wherein, control device is also exported and is connected said motor.
According to above-mentioned corrugated tube torture test apparatus test device; Reciprocating number of times is gathered; Say from the realization angle that at first the reciprocal collection of linear-motion object is the simplest acquisition mode, those skilled in the art is very easy to realize according to the disclosed content of the application.And for counting; Then be controller/the most original functions of intelligent device such as CPU/ single-chip microcomputer; General all is to count through the collection realization of switching value; Especially present a lot of industrial control unit (ICU)s all are integrated with special high-speed counter interface, satisfy than the counting under the higher frequency condition, and it is also relatively easy to implement.Simultaneously,, can satisfy the control of rotating, displacement and frequency through the control of control device to motor, convenient to different corrugated tube selection Different control modes.
Above-mentioned corrugated tube torture test apparatus test device, said control device and display device are integrated in screen and show I.
Above-mentioned corrugated tube torture test apparatus test device, it is touch-screen that said screen shows I.
Above-mentioned corrugated tube torture test apparatus test device, said harvester is the sensor that is used to see off switching value.
Above-mentioned corrugated tube torture test apparatus test device, said drive unit are screw screw mechanism and the motor that connects this screw screw mechanism, and its reciprocating screw that has is equipped with movable corrugated pipe clamp.
Above-mentioned corrugated tube torture test apparatus test device, said drive unit is furnished with guide frame.
Above-mentioned corrugated tube torture test apparatus test device, said guide frame is the guide rail that is fixed on the proving installation frame.
Above-mentioned corrugated tube torture test apparatus test device, said motor connects said control device.
Description of drawings
Fig. 1 is a kind of corrugated tube torture test apparatus test device left side TV structure synoptic diagram according to the utility model.
Fig. 2 is the front view corresponding to Fig. 1.
Among the figure: 1, frame, 2, motor, 3, guide rail 4, corrugated tube clamp device, 5, display system, 6, leading screw.
Embodiment
Attaches Fig. 1 and 2 with reference to explanation; To existing corrugated tube fatigue tester; Can keep most realization, have the corrugated pipe clamp that is used for spacer dimple pipe two ends, drive an end corrugated pipe clamp and drive unit that corrugated tube is radially being moved reciprocatingly; Also comprise the harvester of gathering said drive unit to-and-fro movement number of times, input connects the control device and the display device that is used to show the to-and-fro movement number of times of this harvester.
Referring to Fig. 1, what corrugated pipe clamp device 4 was represented is movable anchor clamps, realizes being connected on the screw of rigidity through tripod, guarantees the verticality of corrugated tube in Fig. 1, avoids occurring bigger additional load.In Fig. 1 corrugated pipe clamp device 4 under, be exactly another anchor clamps, be fixed on the frame 1, two anchor clamps have relative kinematic relation.
For realizing the collection of stretching/compression, at first should be collecting part, gathering has various ways, especially in the face of straight-line object the time.In another instance, collection can show as feedforward, like the output of controller, counts through the number of times that controller control motor 2 changes counter-rotating.Then be to use feedback to realize in another example, feedback is main through sensor, and what sensor a kind of saw off is switching value, like travel switch, near switch, satisfies the counting of counter or the built-in counter of controller.
For another example, correlation type photoelectric sensor is gathered through out-of-date at screw, sees a switching value off, and certainly, making a round trip has twice and gathered, and just can obtain reciprocal number of times through a simple logical operation.
A kind of preferable selection is that said control device and display device are integrated in the apparent I of screen, and this structure has the reasonable characteristics of structural compactness, in Fig. 1, shows as reality system.
An instance then is to select said screen to show I to be touch-screen, can to set some operational factor of motor intuitively.
Be that drive unit described in the instance is screw screw mechanism and the motor that connects this screw screw mechanism again, and its reciprocating screw that has is equipped with movable corrugated pipe clamp.The screw screw mechanism has displacement control ratio characteristics preferably, can realize rotating through the control to its motor, in addition, if motor 1 adopts stepping or servocontrol, then can realize the displacement control of screw accurately.
In other instance, can adopt hydraulic cylinder to realize the compression and the stretching of corrugated tube, the actuating speed of hydraulic cylinder becomes strict proportional relation with flow, and through flow control, then can control displacement effectively, also satisfies corrugated tube and compresses accurately/stretch.
In preferred embodiment, said drive unit is furnished with guide frame, avoids corrugated tube is produced additional shearing force, influences the detection of corrugated tube.
In some were realized, said guide frame was the guide rail that is fixed on the proving installation frame.
In other are realized, can adopt guide pillar, structure is simpler.
