Further, the fixed briquetting is sleeve, and the upper end closed of the sleeve, the fixed electrode are located in sleeve Upper end, the lower end of sleeve are open;The movable holddown is ladder shaft-like structure, wherein the larger diameter end of movable holddown and sleeve Internal diameter is adapted;The lower end of the sleeve is fixedly connected with retainer ring, and the internal diameter of the retainer ring is less than the major diameter of movable holddown End external diameter and the smaller diameter end external diameter more than movable holddown.
Further, the retainer ring is fixedly connected by screw with the lower end of sleeve.
Further, the fixed electrode and float electrode are copper sheet.
Further, the vertical drive is any one in hydraulic cylinder, pneumatic cylinder, linear electric motors or electric cylinders Kind.
Further, it is to be detachably connected between the workbench and base.
Description of the drawings
Fig. 1 is that a kind of compression displacement amount of detection elastic component of the present embodiment is shown with the structure of the detection means of feedback force relation It is intended to;
Fig. 2 is the structural representation of zero point mechanism in the present embodiment.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is below in conjunction with drawings and Examples, right The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and It is not used in the restriction present invention.
As shown in figure 1, the compression displacement amount of the detection elastic component of the present embodiment is included with the detection means of feedback force relation Frame, vertical drive 1, workbench 7, displacement transducer 4 and zero point mechanism 2.Wherein frame includes base 5 and support 6, erects The top of support 6 is fixed on to driving means 1, the lower end of vertical drive 1 is fixed in zero point mechanism 2, filled by vertical driving Put 1 driving zero point mechanism, 2 in the vertical direction movement.Force transducer 3 is provided between zero point mechanism 2 and vertical drive 1. Displacement transducer 4 is arranged in vertical direction on base 5, is being erected by the zero point mechanism 2 that vertical drive drives for detection Nogata displacement upwards.
Preferably, vertical drive is selected from any one in hydraulic cylinder, pneumatic cylinder, linear electric motors or electric cylinders, especially The best results of electric cylinders.
Workbench 7 in the present embodiment is for carrying, fixation elastic component 8 to be measured, and the workbench 7 is located on base 5 and position In the underface of vertical drive 1.Preferably, for being detachably connected between workbench 7 and base 5, by more changing jobs Platform 7 makes the detection range of detection means wider to detect further types of elastic component.
Used as the improvement of the present embodiment, wherein zero point mechanism 2 includes fixing briquetting 21 and is relatively fixed briquetting 21 vertical The movable holddown 24 that direction is flexibly connected, on fixed briquetting 21, one end relative with movable holddown 24 is provided with fixed electrode 22, living The one end fixed with fixed briquetting 21 on dynamic pressure block 24 is provided with float electrode 23, and under original state, float electrode 23 is electric with fixed Gap is provided between pole 22.Preferably, float electrode 23 is copper sheet, float electrode 23 and fixed electrode 22 with fixed electrode 22 Conducting electric wire is connected with, under float electrode 23 and 22 contact condition of fixed electrode, circuit turn-on sends the signal of telecommunication to displacement sensing Device 4, displacement transducer 4 record displacement initial position now.
Preferably, the fixed briquetting 21 in the present embodiment is sleeve, the upper end closed of the sleeve, wherein fixed electrode 22 Upper end in sleeve, the lower end of sleeve are open.Movable holddown 24 is ladder shaft-like structure, and wherein movable holddown 24 is big straight Footpath end is adapted with the internal diameter of sleeve.The lower end of sleeve is fixedly connected with retainer ring 26, and the internal diameter of the retainer ring 26 is less than activity The larger diameter end external diameter of briquetting and the smaller diameter end external diameter more than movable holddown, by retainer ring by the larger diameter end of movable holddown It is limited in sleeve, and the smaller diameter end of movable holddown is stretched out outside sleeve by the internal diameter of retainer ring.The advantage of the structure is, Gu Determine ring and only play to prevent movable holddown effect detached with fixed briquetting, the lower end stress of movable holddown from vertically moving upwards In dynamic process, not by any resistance, it is ensured that the accuracy that the reaction sensitivity of zero point mechanism and displacement initial position judge.Make For preferred, retainer ring 24 is fixedly connected by screw 26 with the lower end of sleeve.
The compression displacement amount of the present embodiment detection elastic component is as follows with the Cleaning Principle of the detection means of feedback force relation, will Detected elastic component 8 is fixed on workbench 7, drives zero point mechanism descending by vertical drive, by displacement transducer reality When detect the displacement of zero point mechanism.Contact with elastic component to be detected when zero point mechanism comes downwards to movable holddown, movable holddown Stop descending under the stop of elastic component, now elastic component is also uncompressed, and zero point mechanism continues traveling downwardly, until fixed briquetting On fixed electrode contact with the float electrode on movable holddown, movable holddown starts the elasticity of compression in the presence of fixed briquetting Part.Now, send the signal of telecommunication after the conducting of fixed electrode and float electrode to displacement transducer, record that elastic component compressed just Beginning position.After the completion of compression, zero point mechanism is up, and movable holddown is separated with fixed briquetting in the presence of self gravitation.
The compression displacement amount of above-mentioned detection elastic component and the detection means of feedback force relation, simple structure, Cleaning Principle letter Single, cost is relatively low, while accuracy of detection is higher, can the initial position that compressed of accurate detection elastic component, and then passed by displacement Sensor detects the compression displacement of elastic component, while the feedback force of elastic component is detected by force transducer, in compression displacement and feedback force In the case of accurately, the conclusion with regard to relation between compression displacement amount and feedback force for drawing is analyzed more accurate.
In a word, presently preferred embodiments of the present invention is the foregoing is only, it is not to limit the present invention, all in the present invention Spirit and principle within any modification, equivalent and the improvement made etc., should be included in protection scope of the present invention it It is interior.
