[description of drawings]
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is the diagrammatic cross-section of Fig. 1.
[embodiment]
Specific embodiment one, as shown in Figure 1, 2 adopts stepper motor 2 as power source, and stepper motor 2 connects by shaft coupling 22 with screw mandrel 9, drives screw mandrels 9 by stepper motor 2 and rotates; Moving seat 5 interstitial holes is threaded hole, cooperates with screw mandrel 9; Two stomidiums are straight hole, cooperate with guide rod 10; When screw mandrel 9 rotates under the drive of stepper motor 2, move seat 5 and be driven, do seesawing along guide rod 10; Guide rod 10 and screw mandrel 9 are fixed on screw mandrel holder 11 and the bearing seat 23, and guide rod 10 plays the effect of guiding.
Detect pin 5 and be enclosed within on the probe of thrust meter 3, tight by screw retention.Thrust meter 3 by screw retention on holder 1.
The exchange membrane stationary installation is fixed on and moves on the seat 5, and the exchange membrane stationary installation comprises chassis, rubber blanket 12 and platen 6, and the chassis comprises rotating disk 7, rotary disk basement 8 and bearing 19.The center of rotating disk 7 is rotatable to be fixed on the rotary disk basement 8, and platen 6, rubber blanket and rotating disk are provided with at least two and detect hole 25, passes for detecting pin 4.Four of designs detect holes in the present embodiment, have both realized that clamping primary ions exchange membrane can finish the repeated detection test, can not cause detecting hole contraposition difficulty again.The hole of platen 6 and rotating disk 7 is to after good, and on rotating disk 7, the centre is lined with rubber blanket 12 by screw retention, fixing lithium proton-exchange-membrane between rubber blanket 12 and the rotating disk 7.Because amberplex is extremely thin, and very soft, if directly pressing amberplex to have the part, cannot keeps under control platen 6, so adopt rubber blanket 12 to press, utilize flexible these characteristics of rubber blanket to push down amberplex fully.Have on rotating disk 7 and the surface that rotary disk basement contacts four along the center of circle equally distributed pilot hole, on the pilot hole swing-around trajectory, be provided with groove on the rotary disk basement 8, be provided with resilient clamp member in the groove, resilient clamp member comprises spring 15 and steel ball 13, spring 15 1 ends are fixed on the rotary disk basement 8, and the other end is steel ball 13 fixedly.When rotating disk 7 rotation, by spring 15 steel ball 13 is compressed into pilot hole on the rotating disk 7, rotating disk 7 is stopped the rotation, thereby will detect 25 location, hole, make the position of detecting hole 25 just in time relative with detection pin 4.Present embodiment can carry out four stations to be fixed.Bearing 19 is fixed on and moves on the seat 5, rotary disk basement 8 is fixed on the bearing 19 by rotating shaft 14, can rotate along rotating shaft 14, it is for convenience of the clamping amberplex that rotary disk basement 8 rotates along axle 14, just more convenient when rotary disk basement 8 is changed into horizontality clamping amberplex.Bearing 19 is provided with the fixedly pin 18 of rotary disk basement 8, because rotary disk basement 8 is movable, needs to add a location and could keep motionless under vertical state in testing process.
Earlier platen 6 and rubber blanket 12 are removed during use, amberplex is clipped in rubber blanket 12 and walks around and coil between 7, again platen 6 is fixed.Detecting pin 4 is installed on the thrust meter 3; Hole aim detecting pin 4 on the platen 6; The speed setting that will puncture is good, starts stepper motor 2, and stepper motor 2 drives and moves seat 5 and be moved to the left, and according to the distance of setting, confirms to detect acupuncture and crosses amberplex, reads the numerical value of thrust meter 3, can draw the intensity that pierces through of under setting speed amberplex; Stepper motor 2 counter-rotatings make mobile seat 5 get back to reference position.Rotate rotating disk 7 with hand, rotate 90 degree, sensation steel ball 13 is compressed into pilot hole, and can carry out the test second time this moment to amberplex.By that analogy, can carry out testing with the 4th time for the third time.
Stepper motor can require to set friction speed according to difference by PLC (programmable controller) control.
Specific embodiment two, different with specific embodiment one be that thrust meter 3 is fixed on and moves on the seat 5, the exchange membrane stationary installation is fixed on the holder 1.
Propulsion system in the foregoing description can also be cylinders.
In sum, the utility model is simple in structure, the accuracy of detection height, and the detection efficiency height can be realized the detection of multiple simulated conditions.
