Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.In addition,, in each embodiment of described the present invention, involved technical characterictic just can combine mutually as long as do not form each other conflict.
Fig. 1 is the structural representation of the embodiment of the present invention, and Fig. 2, Fig. 3 are the partial enlarged drawing that is denoted as the measuring unit of a-quadrant in Fig. 1.In Fig. 1, frame 1 is cuboid framework, is mainly used in supporting role, and wherein the seamed edge on length direction is the longest.Computer system 9 is positioned at frame left part, calculates and controls for measuring process, and two seamed edges in the part of right side on frame length direction install respectively two guide rails of a pair of supporting guide pair 2.
In Fig. 1, back-up roller 3 quantity are two, back-up roller is parallel to each other and is all fixed on the guideway of two seamed edges of frame length direction and vertical with these two seamed edges, be respectively the first back-up roller, the second back-up roller in the middle of the frame rightmost side and frame, two back-up rollers are in the same plane, and back-up roller stretches out the part outside rail clamp 5 for supporting rolling linear guide.Two back-up rollers in the present embodiment in supporting guide pair 2 reciprocally slide, for changing the first back-up roller and the second distance supporting between rolling, the distance that changes both by movement ensures the rolling linear guide with damper of stable support different length, and between the rolling linear guide of applicable different length and damper, oil film thickness is measured.In the present embodiment, back-up roller quantity is two, all removable, but in the present invention, the quantity to back-up roller does not limit.
The lower surface of the rail clamp 5 with damper 10 is installed with 3 cover measuring units 7, but in the present invention, the quantity of measuring unit 7 is not limited.In Fig. 2, a measuring unit 7 includes magnet base 15 and displacement transducer 16.Displacement transducer 16 is fixedly linked by chuck and magnet base 15, and magnet base 15 is fixed on rail clamp 5 bottom surfaces by rotating switch, and displacement transducer 16 is for measuring the distance between distance and gauge block and the guide rail between damper and guide rail.On rolling linear guide 6, be positioned at damper 10 two ends and be separately installed with positioning sliding block 11 with damper place separated by a distance, in the embodiment of the present invention, positioning sliding block 11 quantity are two, but the present invention does not limit the quantity of positioning sliding block, cover described two positioning sliding blocks 11 and damper 10 with positioning cover plate 12, thereby both are fixed.Change rail clamp 5, magnet base 15 and the displacement transducer 16 of different size according to the rolling linear guide different model with damper, magnet base 15 by magnetic-adsorption in rail clamp 5 bottom surfaces, its easy accessibility, only by changing the measurement of damper oil film thickness on the linear rolling guide that rail clamp 5, magnet base 15 and displacement transducer 16 are applicable Multiple Type.
In described frame 1, fixed installation is useful on the control enclosure 8 that starts or close measurement, and in the present embodiment, control enclosure 8 is arranged on the seamed edge of length method, but the present invention does not limit the position of control enclosure 8.
In the present invention, the installation process of magnet base 15 and displacement transducer 16 is:
Before measurement, first select magnet base 15 and the displacement transducer 16 of suitable size according to the secondary model of tested guide rail, and both are linked together.
Then, displacement transducer 16 is stretched into from rail clamp bottom surface mounting hole 13, displacement transducer 16 vertically stretches into ensure that from mounting hole 13 its nozzle is vertical with working face of guide rail, adjusted position displacement sensor 16 is to regulate the distance of this sensor nozzle and rail clamp bottom surface, until ensure that magnet base 15 touches rail clamp bottom surface and this sensor nozzle and the working face of guide rail spacing of being separated by, magnet base 15 touches behind rail clamp bottom surface to be adsorbed on bottom surface, now rotate magnet base switch, magnet base is adsorbed and be fixed on rail clamp bottom surface.Now, magnet base 15 is firmly adsorbed on rail clamp bottom surface and displacement transducer 16 nozzles are vertical with working face of guide rail.
Measuring process is two steps:
The first step is his-and-hers watches: by gauge block 14, just to displacement transducer 16 and be close to guide rail upper surface, the value that now displacement transducer 16 is measured is for to tabular value A1, and A1 is shown in shown in Fig. 2 and Fig. 3, be on sensor nozzle and gauge block and guide rail binding face between vertical range.
Second step is for measuring: remove gauge block 14, shift positioning cover plate 12 onto measuring position, now, damper 10 moves to measuring position thereupon, reading the now value of sensor is measured value A2, A2 as shown in Figure 3, A2 is the internal face spacing being parallel to each other with working face of guide rail on sensor nozzle and damper, because sensor nozzle distance is certain, the binding face of gauge block and working face of guide rail are at grade, A1 equals sensor nozzle and working face of guide rail distance, gets final product to obtain damper oil film thickness=A2-A1 now.In order to measure damper total length each several part oil film thickness, 3 measurement points of operated by rotary motion, each measurement point is averaged after being added by the measured value of aforementioned measuring method again, is the oil film thickness into damper, but in the present invention not the quantity to measurement point specifically limit.
In the present invention, working face of guide rail is the stress surface on guide rail, is also the face paralleling with middle guide fixture of the present invention.
Apparatus of the present invention can be measured the oil film thickness between different model damper and rolling linear guide, and versatility is stronger.Can adopt special Survey Software to coordinate high-speed data acquisition card to measure, measuring process is simple and convenient, and accurately and reliably, measurement mechanism financial cost is low for measurement result, can be used as the measuring equipment of the batch production of the linear rolling guide with damper.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present invention; not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
