Be described in further detail as follows:
A whole set of experimental rig of the present invention as shown in Figure 1, it mainly comprises: inside casing, Z-direction lifting foot (4) and end effector.
Inside casing as shown in Figure 2, X-direction two body side frame installed inside guide rails are connected with the Y-direction sliding beam by guide rail slide block.On framework X-direction framework one side, ball-screw is installed, is responsible for the sliding beam X-direction and moves.At Y-direction sliding beam upper mounting rail and leading screw, end effector is connected with this sliding beam by guide rail slide block, realizes the slip of end effector Y-direction under leading screw drives.
The structure of Z-direction lifting foot is as shown in Fig. 3,4, and the lifting foot comprises: ball-screw, rolling guide, handwheel, protective cover, installing plate, spherical linkage.The protective cover of four lifting foots is connected with framework by bindiny mechanism respectively, and lifting vola section is fixed on the workbench of workpiece, and handwheel is placed in lifting foot top, links together with ball-screw, can come the swing roller leading screw to realize feeding by rotating handwheel.The two end supports bearing block of ball-screw and the protective cover of lifting foot are fixed together; nut and protective cover upper end are fixed together; can realize the relative motion of protective cover and installing plate by the driving of ball-screw; thereby the height of realizing the lifting foot changes, and then the luffing angle of drive inside casing changes.A side at installing plate is equipped with guide rail 22, is responsible for the guiding of Z-direction.A spherical joint bearing 10 is arranged at the bottom of lifting foot, and the lifting foot is connected with platen by this bearing, can tolerate that the angle between lifting foot and workbench can be regulated within the specific limits.Lifting foot top is equipped with handwheel, is responsible for the posture adjustment of whole 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 as shown in Fig. 8,9, end effector is comprised 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 hold down gag direction of exerting pressure along the normal direction of surface of the work, electric main shaft is also along the normal direction feeding simultaneously.The detection of normal direction realizes by normal direction sensor 23, and normal direction sensor 23 is attached to hold-down head 7 one sides, the normal direction on measuring workpieces surface accurately.
Inside casing is connected with the lifting foot by bindiny mechanism 17, and bindiny mechanism 17 as shown in Fig. 5,6, is a cross sliding track mechanism, can bear moment of flexure and the slip of X, Y both direction.Have in the present invention four bindiny mechanisms 17, one of them bindiny mechanism is fixed, and two other bindiny mechanism's Pipelines with Single Direction Compensation remains bindiny mechanism's bidirectional compensating, as shown in Figure 7.
The adjusting of hold down gag direction realizes by the handwheel that is arranged on four liftings foot top, and adjustment process as 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 is connected with Z-direction slide rail in end effector, can realize the feeding of Z-direction.Hold-down head is with cylinder, and thrust realizes by the pressure of cylinder, can apply accurately thrust.The feeding of electricity main shaft realizes by two parts: the first, and in the process of adjusting handle, the height of lifting foot reduces, and causes at last end effector close to surface of the work, and namely electric main shaft has been realized first step feeding; The second step feeding realizes by the ball-screw on end effector, and along normal direction during with Work-sheet pressing, ball-screw drives electric main shaft along Z-direction feeding, processing work when hold-down head.
Concrete using method is:
(1) whole experimental rig is fixed on workbench, relies on the base (in Fig. 3,4, parts 7) of four Z-direction lifting foots to be connected with the workbench bolt.
(2) when needs when the surface of the work assigned address is holed, regulate simultaneously X-direction leading screw 19 on inside casing 1 and the Y-direction leading screw 18 on end effector mobile platform 12, can move to position to be processed to end effector 13, can realize thus hovering on the optional position on surface of the work.
(3) be on the normal direction of surface of the work adding electric main shaft (in Fig. 8, parts 9) and the hold-down head (in Fig. 8,9, parts 7) that must guarantee man-hour on end effector.Detect the normal direction of surface of the work by the normal direction sensor on hold-down head (in Fig. 8,9, parts 23), if electric main shaft and hold-down head are not on normal direction, regulate respectively the handwheel (in Fig. 3, parts 15) on the sufficient top of four Z-direction liftings, the height of every lifting foot is changed, the luffing angle of the framework that is connected with the lifting foot also can change, and then the hold-down head on the drive end effector 7 and the right direction of electric main shaft 9 also change, be adjusted to always align normal direction till.
(4) relative inclination in adjustment process, can occur with workbench in Z-direction lifting foot, at this moment can be provided by the spherical joint bearing (in Fig. 3, parts 10) of lifting foot end the activity of lifting foot in a taper scope.
(5) bindiny mechanism is a cross sliding track mechanism, and in adjustment process, the lifting foot changes with the relative position of inside casing, and the displacement that this change in location causes mainly compensates by this bindiny mechanism.
(6) when regulating end, begin workpiece is processed, hold-down head on end effector (in Fig. 8, parts 7) under the thrust of cylinder (in Fig. 8, parts 29) along guide rail direction (being the Z-direction of single unit system) feeding, workpiece pressing, thrust can be regulated by air pressure.Then ball-screw promotes electric main shaft (in Fig. 8, parts 9) feeding under the driving of motor, completes the processing of workpiece.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
