Description
Technical field
The utility model relates to a kind of corrugated tube life test machine, is applicable to the life-span of all kinds of corrugated tubes of test.
Background technology
Prior art adopts the mechanical reciprocation cycle bellows of motor-driven to reach the purpose of test life.Its shortcoming is that control corrugated tube expanding-contracting action has pause; The length and the speed of elongation and compression are disproportionate in the telescopic process; That is to say and be not evenly to carry out stretching motion; This produces adverse factors to the effect of corrugated tube test life and the reliability of test life, causes the test life data inaccurate or imperfect.
The utility model content
The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of reasonable in design is provided, and can carry out the corrugated tube life test machine of stretching motion evenly.
The utility model addresses the above problem the technical scheme that is adopted: a kind of corrugated tube life test machine comprises column, hold-down nut, top board, adjuster bar, upper chuck, lower chuck, base plate, underframe, tension-compression sensor, supporting plate, travel switch, counter, limited block, control system; Column is fixed on the base plate, and base plate is fixed on the underframe, and top board is fixed on the column, and adjuster bar is installed on the top board, and hold-down nut is sleeved on the adjuster bar, and upper chuck is fixed on the adjuster bar; Tension-compression sensor one end is connected with lower chuck, and the other end is connected with supporting plate; The supporting plate slip cap is contained on the column; Travel switch is fixed on the base plate; Limited block is fixed on the supporting plate, and limited block cooperates with travel switch; Counter is fixed on the base plate, and counter cooperates with supporting plate; Tension-compression sensor, travel switch, counter all are connected with control system; It is characterized in that: also comprise the air cylinder driven system, the air cylinder driven system comprises cylinder and solenoid valve, and cylinder is connected through tracheae with solenoid valve; The piston and the supporting plate of cylinder are fixed, and solenoid valve is connected with control system.
The utility model compared with prior art has the following advantages and effect: the utility model structure fabrication is simple, and versatility is higher, lays easyly, and operation is convenient, can carry out stretching motion evenly, and the test life data are accurately with complete.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is done further to specify.
Embodiment:
Referring to Fig. 1, the utility model embodiment comprises column 1, hold-down nut 2, top board 3, adjuster bar 4, upper chuck 5, lower chuck 16, tension-compression sensor 6, supporting plate 7, base plate 8, underframe 10, control system 12, counter 13, travel switch 14, limited block 15, air cylinder driven system.
The air cylinder driven system comprises cylinder 9, solenoid valve 11, source of the gas.Cylinder 9 and solenoid valve 11 are connected through tracheae, and solenoid valve 11 controls are to the intake and exhaust of cylinder 9, make the piston motion of cylinder 9.The piston of cylinder 9 and supporting plate 7 are fixing, and solenoid valve 11 is connected with control system 12, and solenoid valve 11 is connected with source of the gas through tracheae.
The utility model principle of work: corrugated tube 20 1 ends are fixing with upper chuck 5, and the other end is fixing with lower chuck 16.Adopting the air cylinder driven system is power source, drives supporting plate 7 and moves up and down.Utilize travel switch 14 and the means for adjusting limit of movement that limited block 15 is formed that cylinder 9 piston motion positions are controlled; Limited block 15 is with after travel switch 14 contacts; Travel switch 14 sends signal controlling contactor 19 and breaks off or closure; Contactor contactor 19 control electromagnetic valve 11 realize the air inlets switching-over, thereby have controlled moving up and down that the piston of cylinder 9 do not stop.The piston of cylinder 9 ceaselessly moves up and down, and it is flexible to drive corrugated tube 20 through supporting plate 7 and tension-compression sensor 6.Power value in 6 pairs of Compression and Expansion processes of tension-compression sensor is measured in real time, is gathered and is handled by 17 pairs of data of computer system, and be depicted as curve map automatically.In addition, on counter 13 fixing on the base plate 2, a shift fork is arranged, when supporting plate 7 moves up and down; Ceaselessly break away from and press to shift fork; Whenever press to disengaging once, counter 13 will be counted once, and counting shows that once corrugated tube 20 stretches once; After being tested to certain number of times (as 5000 times), finish to stretch and compression.After experiment finishes; The data that can collect through tension-compression sensor 6 and the numerical value of the treated curve map sum counter 13 that is depicted as automatically; Observe power value in the corrugated tube Compression and Expansion process and change and reflect and be worth change procedure the fatigue lifetime of corrugated tube, thereby can draw the serviceable life of corrugated tube 20 basically.According to the numerical value on the counter 13, and reveal test and can draw corrugated tube ultimate life value through corrugated tube being carried out the helium mass spectrum.
