Pressure cap 4 is connected with pedestal 1 by standard screws by the screw hole of both sides.The rigidity of pressure cap and stability thereof are one of key factors realizing for laying mechanism its function, and for guaranteeing the rigidity of pressure cap, design adopts No. 45 Steel materials to process, and before processing, adopts rational heat treatment mode, promotes the mechanical property of pressure cap.
Pre-pressure ring 31: being arranged on respectively in the described seat hole under pressure sensor 3, adopting 1Cr18Ni9Ti materials processing to form, is the adjustment member of pressure sensor precompression size.
Force transmission mechanism 2, for guaranteeing that force transmission mechanism transmits the accuracy of power, between force transmission mechanism 2 and slip pre-tightening sleeve 13, apply certain pretightning force, eliminate the gap of radial direction, and guarantee that the present invention is after assembling, under self gravitation effect, the entirety that force transmission mechanism 2 and below attaching parts thereof form can slip, guarantees that the frictional force that pretightning force produces equates with its gravity.
13 designs of slip pre-tightening sleeve adopt ball bearing nested structure, are placed in pedestal 1, form the raceway of upper and lower fine motion.In composite automatic placement process, because pressure roller 61 is subject to radial and axial pressure, by the transmission successively of drawn cup needle roller bearing 623 and needle roller thrust bearing 622, roller mount pad 62, float base 5, force transmission mechanism 2, finally pass to pressure sensor 3, thereby cause the distortion of pressure sensor 3, drive upper and lower fine motion.
The base 5 that floats is force transmission element, and design adopts No. 45 Steel materials to process, and one 1～2mm shallow slot is arranged at bottom, the installation direction of restrict rollers mount pad 62.
Stop pin 53 is for limiting base 5 the rotatablely moving using force transmission mechanism 2 as rotating shaft of floating, and design adopts interference fits, is installed in the bottom blind hole 12 of pedestal 1, with the matched in clearance that is connected to of the respective through hole 52 of unsteady base 5.
Magnetic force piece 55 adopts magnet, in the vertical direction pair roller mount pad 62 is fixed, prevent that roller mount pad and pressure roller 61 from rolling under state because gravity drops non-, this kind is fixedly connected with mode and is highly susceptible to installation and the replacing of roller mount pad and pressure roller, thereby adapts to the lay of the composite material prepreg of different in width specification.
Needle roller thrust bearing 622 and drawn cup needle roller bearing 623 are arranged in roller mount pad 62 side installing holes 621, realization axially and is radially accurately located pressure roller 61, in composite automatic placement process, while making pressure roller be subject to axial and radial effect power, can not be subjected to displacement, and can rotate freely without catching phenomenon.
Inner side guide positioning plate 71 and outside guide positioning plate 72 adopt aluminum alloy materials to process, the medial surface of pedestal 1 is close in guide positioning plate 71 1 sides, inner side, the lateral surface of the base 5 that floats is close in guide positioning plate 72 1 sides, outside, inner side guide positioning plate 71 and outside guide positioning plate 72 form a upper and lower passage, and the base 5 that makes to float can only do upper and lower fine motion within the scope of it.In addition, inner side guide positioning plate 71 has two magnetic force piece installing holes, and described magnetic force piece 55 is arranged in fact in this magnetic force piece installing hole.
Hexagonal tack holding screw in holding screw 15 employing standards, is assemblied in the set screw hole 14 of pedestal (set screw hole 14 is standard thread pilot hole), and effect is the rotation that prevents force transmission mechanism 2 when assembling.In the situation that not affecting force transmission mechanism 2 and being connected with pressure sensor 3, to force transmission mechanism 2 and being connected of unsteady base 5 applying screw-down torque, rear holding screw 15 inner faces have been assembled separation with force transmission mechanism 2.
Signal connects: each pressure sensor 3 is connected with outside signal acquisition process module by its signaling interface and connecting line, realizes acceptance, processing and feedback to lay pressure detecting signal.
The present invention that above embodiment forms, its operation principle is as follows:
In composite material prepreg automatic placement process, the axis of pressure roller should keep vertical with the normal for the treatment of lay face all the time, if composite material prepreg lay pressure is F, the reaction force of lay pressure passes to respectively the pressure sensor of both sides power by pressure roller is F/2, according to varying in size of F, pressure sensor can feed back the different signals of telecommunication, by signal collection treatment system, pressure sensor is fed back to the signal going out and converts the outside readable data signal of laying control system to.The size that the selection of pressure sensor measurement range S is is F according to lay pressure is determined, because pressure sensor is in it measures 40%～80% interval of range S, certainty of measurement is the highest, the selection of the range S that therefore pressure sensor is selected, meet S × 60%=F/2, i.e. S=5F/6.Before assembling and setting, according to the size of composite material laying technological requirement lay pressure F, by demarcating the data signal that counterweight changes out the signal of telecommunication of pressure sensor feedback and pressure sensor signal collection processing system implementing, demarcate; label taking fixed-point number is n(n=1 2,3; ...); and the corresponding change curve between the signal of telecommunication that goes out pressure sensor according to the numerical fitting of n calibration point and power, the demarcation of the getting n that counts is larger, and the change curve simulating is got over close to actual theoretical curve.In composite automatic placement process, when lay surface occurs that inclination or curved surface change, the power that pressure roller two ends pass to pressure sensor also there will be corresponding variation, outside laying control system can be according to the unlike signal of pressure sensor feedback, do comparative analysis with the change curve simulating in pressure sensor calibrating, and control laying head and make corresponding adjustment, adjust the attitude of composite material prepreg laying mechanism, make the axis of pressure roller keep vertical with the normal for the treatment of lay face all the time, thereby keep the uniformity of lay pressure, reach the object of conformal lay.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, the common variation that those skilled in the art carries out within the scope of technical solution of the present invention and replacement all should be included in protection scope of the present invention.
