Definitions
- the present invention relates to a device for fixing and adjusting a member to be supported, such as a precision optical element.
- the latter consist of six spacers of adjustable length connecting the member to be positioned and oriented at the base. These six adjustable lengths provide six degrees of freedom corresponding to three position coordinates and three orientation angles.
- the essential properties of these devices are the precision of the adjustment that can be obtained, the amplitude of the adjustment range, as well as their stiffness.
- the present invention aims to provide a fixing and adjustment device with two degrees of freedom which, assembled in groups of three, gives a fixing and adjustment assembly with six degrees of freedom of the above type.
- the invention aims to provide such a device giving a high adjustment precision.
- the invention firstly relates to a device for fixing and adjusting a member to be supported, such as a precision optical element, characterized in that it comprises:
- each of said levers comprising two arms arranged in a triangle and connected together to one of the vertices of the triangle, each of said levers being articulated on said base at its respective vertex, a first of the two arms of each lever being extensible and connected at its free end to means for fixing to said member;
- each of said levers is articulated on the base around an axis substantially perpendicular to the plane of said lever.
- each of said levers can be articulated on the base by means of a blade substantially perpendicular to the plane of the respective lever.
- the two levers are substantially in the same plane.
- first arm of each lever is articulated on the second arm at the respective apex of the lever.
- the first arm of each lever is articulated on said fixing means.
- each of the articulations can comprise at least two blades, one of which is substantially in the plane of the respective lever and the other is substantially perpendicular to this plane.
- said other blade may be in a plane substantially parallel to the first arm of the respective lever.
- the hinge blade of the lever on the base may in particular be in a plane substantially parallel to that of the lad ite other blade.
- said blades can be made in one piece with the respective lever.
- the joints are therefore free of play.
- the blades provide opto-mechanical filtering of the adjustment and of the disturbances.
- said adjustment means are adjustment means without play. More particularly, said adjustment means may comprise a thrust finger actuated by a motor and acting on said second arm of the respective lever against the action of elastic means.
- said motor can be a piezoelectric actuator.
- Said motor can be removable.
- the invention also relates to a set for fixing and adjusting a member to be supported, such as a precision optical element, characterized in that it comprises three devices as described above, of which the respective fixing means are arranged to be fixed to said member at three separate points.
- the three devices can be arranged around a central axis in rotation symmetry of substantially 120 °.
- FIG. 1 is an elevational view of a fixing and adjusting device according to the invention
- FIG. 1 is an enlarged view of the detail I I of Figure 1;
- FIG. 3 is a view along arrow I I I of Figure 2;
- Figure 4 is a view similar to Figure 2 illustrating the operation of the device.
- FIG. 5 is a diagram of a fastening and adjustment assembly according to the invention.
- the device of Figure 1 first comprises a support base 1 rigidly fixed by any suitable means to a mounting platform 2.
- the base 1 supports two piezoelectric actuators 3 supplied by electrical conductors 4 and arranged each to move a pushing finger 5. After adjustment, the fingers 5 can be blocked by means not shown and the actuators can optionally be removed. It will be observed that this blocking does not disturb the device.
- Two substantially symmetrical triangular levers 6 are each mounted at one of the ends of the base 1, substantially in the same plane.
- Each lever 6 is formed of two arms 7 and 8 of generally square section connected together at one of the vertices 9 of the triangle which they delimit.
- the end of each arm 8 adjacent to the arm 7 is articulated on the base 1 about an axis substantially perpendicular to the plane of the levers 6.
- this end of the arm 8 is connected to the base 1 by a blade 1 0 substantially perpendicular to the plane of the levers 6 and substantially parallel to the axis 11 of the arm 7.
- the curvature of this blade ensures the degree of freedom of rotation of the arm 8 in the plane of the lever 6.
- a similar arrangement connects the arm 7 to the arm 8.
- a blade 12 is disposed between these two arms in a plane parallel to the plane of the blade 10 and located at a certain distance from the latter plane.
- Another similar arrangement is formed at the end of the arm
- the blade 1 3 therefore gives the arm 7 a degree of freedom of rotation in a plane perpendicular to the plane of the levers 6.
- each arm 7 opposite the arm 8 is connected to a fixing piece 14 by an arrangement similar to two perpendicular blades.
- a first blade 1 5 is interposed on the end of the arm 7 in the plane of the levers 6 and a second blade 16 connects this end to the part 14.
- the blade 1 6 is perpendicular to the plane of the levers 6 and passes through the axis 1 1.
- the end of each arm 8 opposite the apex 9 of the respective lever 6 is urged by one of the fingers 5 against the action of a spring 1 7.
- the finger 5 is arranged to push the end of the arm 8 so as to l drive in rotation around the articulation formed by the blade 10. It can be seen in FIG.
- the adjustment is therefore multiplied in the quantity desired at design.
- this adjustment does not degrade the element to be adjusted, the blades 10, 12, 13, 15 and 16 ensuring both the kinematics of the device and the mechanical filtering of the forces and movements applied at the level of the fixing part 14 .
- FIG. 5 shows three devices such as the one just described.
- the three bases 1, 1 a and 1 b are mounted in the same plane on a platform 17, at 120 ° from each other around an axis 18.
- Each pair of arms 7, 7a and 7b provides two degrees of freedom, so that the assembly is at six degrees of freedom.
- the position and orientation of the object 19 are adjusted using the six actuators.
- the six adjustments are not independent, each adjustment of an arm 7 generally leading to a modification of the length and / or the orientation of the other arms.
- Those skilled in the art will be able to adopt the most appropriate global adjustment algorithm.
- the device therefore provides the isostatic, conventional (hexapod configuration) and adjustment functions.
- the base 1, the levers 6 and the fixing part 16 are here made in one piece.
