Further details are as follows:
The a whole set of experimental rig of the utility model is as shown in Figure 1, and it mainly comprises: inside casing, Z are to foot (4) and the end effector of going up and down.
Inside casing is as shown in Figure 2, and X links to each other to sliding beam with Y through the guide rail slide block to two body side frame installed inside guide rails.On framework one side, ball-screw is installed at framework X, is responsible for sliding beam X to moving.To sliding beam upper mounting rail and leading screw, end effector links to each other with this sliding beam through the guide rail slide block at Y, and realization end effector Y is to slip under leading screw drives.
Like Fig. 3, shown in 4, the foot that goes up and down comprises Z: ball-screw, rolling guide, handwheel, protective cover, installing plate, spherical linkage to the sufficient structure of going up and down.The protective cover of four foots that go up and down links to each other with framework through bindiny mechanism respectively, and up-down vola portion is fixed on the workbench of workpiece, and handwheel is placed in sufficient top, links together with ball-screw, can come the swing roller leading screw to realize feeding through rotating handwheel.The two end supports bearing block of ball-screw is fixed together with the protective cover of the foot that goes up and down; Nut and protective cover upper end are fixed together; Can realize the relative motion of protective cover and installing plate through the driving of ball-screw; Thereby the height of realizing foot changes, and then the luffing angle of drive inside casing changes.Side at installing plate is equipped with guide rail 22, be responsible for Z to guiding.A sphere oscillating bearing 10 is arranged at the go up and down bottom of foot, and the foot that goes up and down links to each other with platen through this bearing, can tolerate the angle scalable within the specific limits between up-down foot and the workbench.The sufficient top of going up and down is equipped with handwheel, is responsible for the posture adjustment of entire mechanism, and when guaranteeing the end effector processing work, machine direction is that the normal direction of surface of the work is consistent.
End effector 13 is machining cells of package unit, and like Fig. 8, shown in 9, end effector is made up of motor, ball-screw, electric main shaft, normal direction sensor, hold down gag, rolling guide, cylinder, installing plate etc.Adding man-hour, must guarantee the normal direction of hold down gag direction of exerting pressure along surface of the work, electric main shaft also is along the normal direction feeding simultaneously.The detection of normal direction realizes that through normal direction sensor 23 normal direction sensor 23 is attached to hold-down head 7 one sides, accurately the normal direction on measuring workpieces surface.
Inside casing links to each other with the foot that goes up and down through bindiny mechanism 17, and bindiny mechanism 17 is a cross sliding track mechanism like Fig. 5, shown in 6, can bear the moment of flexure and the slip of X, Y both direction.In the utility model, have four bindiny mechanisms 17, one of them bindiny mechanism is fixed, and the unidirectional compensation of two other bindiny mechanism remains bindiny mechanism's bidirectional compensating, and is as shown in Figure 7.
The adjusting of hold down gag direction realizes that by the handwheel that is installed in four sufficient tops of going up and down adjustment process is shown in figure 10.
Observation is to the direction of measurement of sensor in the process of regulating; Handwheel stops operating when direction of measurement has been aimed at Working position; Show that this moment hold-down head on the normal direction of surface of the work, can guarantee that like this hold-down head can apply thrust along the normal direction of surface of the work.Hold-down head links to each other to slide rail with Z in the end effector, can realize Z to feeding.Hold-down head is with cylinder, and thrust realizes through the pressure of cylinder, can apply thrust accurately.The feeding of electricity main shaft realizes through two parts: the first, in the process of adjusting handle, the height of the foot that goes up and down reduces, cause at last end effector to surface of the work near, promptly electric main shaft has been realized first step feeding; Second stepping realizes through the ball-screw on the end effector, when hold-down head along normal direction during with Work-sheet pressing, ball-screw drive electric main shaft along Z to feeding, processing work.
Concrete method for using is:
(1) the whole test device is fixed on the workbench, relies on four Z to be connected with the workbench bolt to the base (parts 7 among Fig. 3,4) of the foot that goes up and down.
(2) when needs when the surface of the work assigned address is holed; Regulate the Y of X on leading screw 19 and end effector mobile platform 12 on the inside casing 1 simultaneously to leading screw 18; Can move to position to be processed to end effector 13, can be implemented in thus on the optional position on the surface of the work and hover.
(3) be on the normal direction of surface of the work adding the electric main shaft (parts 9 among Fig. 8) and the hold-down head (parts 7 among Fig. 8,9) that must guarantee man-hour on the end effector.Detect the normal direction of surface of the work through the normal direction sensor on the hold-down head (parts 23 among Fig. 8,9); If electric main shaft and hold-down head are not on the normal direction; Regulate the handwheel (in Fig. 3 parts 15) of four Z respectively to the sufficient top of going up and down; The height of the every foot that goes up and down is changed; The luffing angle of the framework that links to each other with the foot that goes up and down also can change, so drive hold-down head 7 and electric main shaft 9 on the end effector right direction also change, be adjusted to always and align till the normal direction.
(4) Z is to going up and down foot in adjustment process, and at this moment meeting and workbench generation opposing inclined can provide sufficient activity in a taper scope by the sphere oscillating bearing (parts 10 among Fig. 3) of the foot end that goes up and down.
(5) bindiny mechanism is a cross sliding track mechanism, and in adjustment process, the relative position of go up and down foot and inside casing changes, and the displacement that this change in location causes mainly leans on this bindiny mechanism to compensate.
(6) when regulating end; Begin workpiece is processed; Hold-down head on the end effector (parts 7 among Fig. 8) under the thrust of cylinder (parts 29 among Fig. 8) along the guide rail direction Z of single unit system (be to) feeding, workpiece pressing, thrust can be regulated by air pressure.Ball-screw promotes electric main shaft (parts 9 among Fig. 8) feeding under the driving of motor then, accomplishes the processing of workpiece.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
