Description

Adjusting platform

Technical Field

The invention relates to the technical field of precision measurement, in particular to an adjusting platform.

Background

Piezoelectric ceramics are functional ceramic materials that can interconvert mechanical energy and electrical energy. When an external force is applied to the piezoelectric ceramic, the piezoelectric sheet generates electric charges, and the pressure is converted into voltage. When an electric field is applied to the piezoelectric sheet, the piezoelectric ceramic sheet is mechanically deformed, and the deformation is proportional to the strength of the electric field.

At present, most of precision instruments adopt piezoelectric ceramics to perform fine positioning and adjustment. For example, the piezoelectric scanning stage uses piezoelectric ceramics as a driving source, and can realize nanometer positioning accuracy by generating very small displacement through controlling small change of voltage.

However, the piezoelectric ceramic is manufactured by a plurality of processes, the manufacturing process is complex, and the manufacturing process is higher in requirements especially in occasions with higher use precision requirements.

Therefore, the adjusting platform cannot deviate in the horizontal direction, and the leveling precision is ensured.

Referring to fig. 2, the driving assembly 600 includes a pulling portion 610 and a power portion 620, wherein one end of the pulling portion 610 is connected to the supporting member 300, and the other end is wound on the power portion 620, and can be unwound or wound by the power portion 620.

Referring to fig. 2, the power unit 620 is disposed in a hollow area in the base body 100 and is mounted on the cylinder wall 110. The power part 620 is located below the base plate 520. The power unit 620 is provided with an output hole 621. The center line of the output hole 621 coincides with the center lines of the mounting hole 350 provided on the support member 300, the threading hole 420 provided on the elastic member 400, and the outlet hole 513 provided on the fixing member 500, so that the drawing portion 610 does not deflect in the up-down direction.

Referring to fig. 2, the fixed end 611 of the traction part 610 is disposed in the mounting hole 350 of the supporter 300 and fixed with respect to the mounting hole 350. For example, the fixed end 611 of the traction portion 610 may be fixed in the mounting hole 350 by an expansion bolt, or other connection methods may be used, which are not limited herein. The free end 612 of the traction part 610 sequentially passes through the coaxial threading hole 420, the outlet hole 513 and the output hole 621 and is wound on the power part 620.

The power parts 620 are provided in three numbers and are uniformly distributed along the center line of the cylinder wall 110. Accordingly, there are three traction portions 610 connected to the corresponding power portions 620. That is, the three sets of driving assemblies 600 are respectively connected to three different positions of the supporting member 300 to apply forces to the different positions of the supporting member 300, so that the three independent elastic members 400 respectively engaged with the supporting member 300 are respectively deformed or at least partially restored to be deformed.

In this embodiment, the power portion 620 is a stepper motor, or other power device that can provide precise movement.

The driving assembly 600 further includes a controller connected to the power unit 620 to control the power unit 620 to drive the traction unit 610 to wind or unwind, and apply different pulling forces to the traction unit 610.

Referring to fig. 2, in the present embodiment, the adjusting platform is in an assembled state, and the fixing member 500 is embedded in the base 100 and located at the first opening 111. The upper surface 521 of the base plate 520 of the fixture 500 does not protrude from the cartridge wall 110. The outer surface of the circumferential wall 510 mates with the inner surface of the cartridge wall 110, and the circumferential wall 510 is secured to the cartridge wall 110 by screws. The convex structure 414 at one end of the elastic element 400 is matched with the low concave part 511 on the fixed element 500, and the convex structure 413 at the other end is matched with the concave part 340 on the supporting element 300, namely, the elastic element 400 is clamped between the supporting element 300 and the fixed element 500. The fixed end 611 of the traction part 610 is connected to the support 300, and the free end 612 passes through the threading hole 420, the outlet hole 513 and the output hole 621 and is wound on the power part 620.

Three elastic members 400 are uniformly arranged in the circumferential direction between the supporting member 300 and the fixing member 500, and thus, a plane can be defined and leveling can be achieved simply and efficiently. In other embodiments, the number of the elastic members 400 disposed between the supporting member 300 and the fixing member 500 may be greater than three, and accordingly, the number of the recesses 340 of the supporting member 300 for engaging with the elastic members 400 may be changed, and similarly, the number of the recesses 511 of the fixing member 500 for engaging with the elastic members 400 may be changed.

The adjusting platform is simple in structure, low in process difficulty and easy to realize, and different leveling accuracies can be obtained by replacing the material of the elastic piece 400. In the case of high precision requirement, the cost is greatly reduced compared with the piezoelectric ceramic.

Before leveling work is carried out on a workpiece to be tested, the three groups of traction parts 610 are wound by a set length, when the traction parts 610 are driven by the power part 620 to wind, the traction parts 610 pull the support part 300 to move downwards and apply pressure on the elastic part 400, and the elastic part 400 is elastically deformed, which can be called as pre-deformation. Then, the upper surface 310 of the support 300 is leveled to be in a horizontal state.

In the process of leveling the workpiece to be tested, if the position of the workpiece to be tested on the supporting member 300 needs to be lifted, the power part 620 drives the traction part 610 to unreel; at this time, the pulling force applied to the supporting member 300 becomes small enough to keep the elastic member 400 in the current deformation amount, and the elastic member 400 at least partially restores to deform to push the corresponding position of the supporting member 300 to move upwards, so as to lift the workpiece to be tested. On the contrary, if the position of the workpiece to be detected needs to be lowered, the power part 629 drives the traction part 610 to perform winding operation; the support member 300 is pulled downward by the pulling portion 610, and the support member 300 compresses the elastic member 400 downward to deform it downward. By adjusting the deformation of the three independent elastic members 400, the displacement of the supporting member 300 in the vertical direction can be realized, and the leveling of the workpiece to be measured can be further realized.

In practical experiments, the material of the elastic member 400 is brass, the elastic modulus of the brass is 140GPa, the Poisson ratio of the brass is 0.34, and the length of the elastic member 400 is set to be 10 mm. The force-bearing area of the single elastic member 400 is 0.0003m²When 0.1N force is applied to the elastic member 400, the amount of deformation of the elastic member 400 is 10nm, and leveling accuracy of a nanometer level can be achieved.

The adjusting platform can be used for leveling work and can also be applied to a nanoindentation measurement technology. For example, the workpiece is placed on the adjusting platform, continuous dynamic ultralow load is applied to the workpiece, nanoscale compression depth is obtained, and mechanical properties of the workpiece can be measured on a nanoscale.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
