Detailed description of the invention
For making those skilled in the art understand better the technical solution of the utility model, underFace is described in further detail the utility model with detailed description of the invention by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1 to Figure 3, the present embodiment provides a kind of oscillating table.
This oscillating table is used in semiconductor machining, workpiece sensing, Aero-Space device attitudeSupporting workpiece in the occasions such as adjustment, lathe calibration, it is preferably small angle oscillation platform.
Concrete, above oscillating table comprises:
Substrate 1, it comprises the first arc-shaped guide rail 11;
Table top 2, it comprises the second arc-shaped guide rail 21 mating with the first arc-shaped guide rail 11,And be supported in substrate 1 by the second arc-shaped guide rail 21;
Rotate export structure 3, it is for exporting rotational motion;
Screw rod 4, its one end is connected with rotation export structure 3;
Nut 5, it is sheathed on screw rod 4 and with screw rod 4 and mates;
Shell fragment 6, on the axial direction of screw rod 4, one end of shell fragment 6 is connected with nut 5,The other end is connected with table top 2, and shell fragment 6 can be compressed on the axial direction of screw rod 4Or stretch.
That is to say, similar with conventional oscillating table, the oscillating table of the present embodiment also comprisesSubstrate 1 and table top 2, table top 2 has the supporting surface 29 for supporting workpiece, and substrate 1It is the basis of table top 2. Table top 2 is supported on base by the arc-shaped guide rail cooperatively interactingAt at the end 1, thereby in the time of arc-shaped guide rail relative sliding in table top 2 and substrate 1, table top 2In substrate 1, swing, and drive the workpiece on supporting surface 29 to swing.
Preferably, the arc of above the first arc-shaped guide rail 11 and the second arc-shaped guide rail 21Protuberance points to below.
That is to say preferably with respect to the horizontal plane " recessed " of above arc-shaped guide railArcs of recesses, thus be conducive to the stability that ensures that table top 2 moves.
Wherein, as a kind of mode of the present embodiment, as shown in Figure 3, above two arcsShape guide rail can comprise the arc groove on the opposite flank that is located at substrate 1 and table top 2, andIn arc groove, be provided with ball 9, therefore two arc grooves are (in other words under ball 9 effectArc-shaped guide rail) can relative sliding, thus drive table top 2 to move in substrate 1.
Certainly, the concrete form of arc-shaped guide rail is various, and those skilled in the art also canIt adopts many other forms of arc-shaped guide rails, as long as can make table top 2 put in substrate 1Moving. For example, the upper surface of the first arc-shaped guide rail 11 also can be cancave cambered surface, and secondThe lower surface of arc-shaped guide rail 21 for be located at convex globoidal on this cancave cambered surface (certainly the twoBall 9, slide rail etc. also can be set), thus convex globoidal can slide on cancave cambered surface.
The oscillating table of the present embodiment also comprises rotation export structure 3, its connecting screw rod 4 (silkThick stick) one end, for driving screw rod 4 to rotate.
Preferably, this rotation export structure 3 is motor, or is for hand handle.
Preferably, substrate 1 also comprises support portion 19, and screw rod 4 is away from rotating export structure3 the supported portion 19 in one end supports.
That is to say, as shown in Figure 2, the other end of above screw rod 4 can be erected at substrateOn 1, thereby ensure the stable of screw rod 4.
Screw rod 4 is provided with nut 5, and nut 5 is connected with one end of shell fragment 6, shell fragment 6The other end connect table top 2. Wherein, shell fragment 6 also claims resilient pivot, is by having bulletProperty material (as metal) form bending laminated structure, therefore bending in the time that its two ends are stressedDegree can change (corresponding entire length also changes), produces the reply of resistance to deformation simultaneouslyPower.
As shown in Figure 2, nut 5 is connected with shell fragment 6 and cannot rotates, therefore when screw rod 4When rotation, nut 5 is understood the axially-movable (i.e. left and right horizontal motion in Fig. 2) along screw rod 4,Thereby in the axial direction of screw rod 4, shell fragment 6 is compressed or stretched, shell fragment 6 is deformed to necessarilyAfter degree, can produce enough restoring forces, drive table top 2 to move, and table top 2 be subject to arcThe restriction of shape guide rail, therefore can produce swing.
Preferably, screw rod 4 and shell fragment 6 are all located at table top 2 belows. It is further preferred,One end of shell fragment 6 is connected with the upside of nut 5, and the other end is connected with the downside of table top 2.
That is to say, as shown in Figure 1 and Figure 2, screw rod 4 and shell fragment 6 can be located to platformFace 2 belows, and more preferably shell fragment 6 is located between table top 2 downsides and nut 5 upsides.Obviously, such structure can make full use of the space of table top 2 belows, thereby reduces to swingThe overall volume of platform.
Preferably, screw rod 4 and the first arc-shaped guide rail 11 projection are in the horizontal direction mutualParallel.
That is to say, as shown in Figure 1, screw rod 4 and the first arc-shaped guide rail 11 (also wrap certainlyDraw together the second arc-shaped guide rail 21) overall bearing of trend be parallel to each other, thereby screw rod 4 canDrive oscillating table motion from the direction of " just ", efficiency is high and avoid unnecessary changeShape.
Visible, because the oscillating table of the present embodiment adopts " screw rod 4 (nut 5)+shell fragment 6 "The kind of drive, between its screw rod 4 and nut 5, closely cooperate thus, between not existing oppositelyGap, wobble accuracy is high; And wherein do not need to use large worm gear etc., thus be easy to processing,Cost is low; Meanwhile, screw rod 4 does not exist and is slidably matched with nut 5, therefore it is little to wear and tear, makesLong with the life-span; In addition, screw rod 4 can be continuously applied very large active force by shell fragment 6,Therefore make large-scale oscillating table become possibility.
Embodiment 2:
