Abstract
The utility model devises a kind of PSTM damping device, is mainly used in PSTM experimental facilities under normal temperature.This damping device comprises framework, crossbeam, steel wire extension spring, regulates platform, object table, rubber pad.Under this device, steel wire extension spring one end is suspended on crossbeam, and the other end suspention regulates platform.Object table is fixed together with regulating platform by bolt, can by object table leveling by knob bolt; Rubber pad is placed on four angles of shock frame, and whole framework is rectified steadily.The utility model compact structure, simple, convenient to load and transport, cost of production is low, and the damping leveling requirement of PSTM experiment under can meeting normal temperature.
Description
Technical field
The utility model relates to scanning type probe microscope field, is specifically related to PSTM damping device field.
Background information
When carrying out scanning imagery with PSTM to sample surfaces, the superfine probe that flying-spot tube front end is fixed and the desired pitch of sample are close to Nano grade.In scanning process, if do not have damping device, the data that extraneous vibration is easy to cause collecting on the one hand are untrue, cause imaging errors, the failure of an experiment; Also easily cause probe and sample to bump against on the other hand, damage probe, cause economic loss.
Existing PSTM damping device directly adopts steel wire extension spring to carry out damping leveling, and steel wire extension spring upper end is fixed on framework, and lower end directly suspends object table in midair.Leveling object table is carried out by regulating the upper end of each steel wire extension spring.Shortcoming is: the structural symmetry changing steel wire extension spring, affects damping effect.The utility model regulates object table by direct knob bolt and regulates the spacing of platform to carry out leveling object table, and under this device, steel wire extension spring one end is suspended on crossbeam, and the other end suspention regulates platform.Object table is fixed together with regulating platform by bolt, by object table leveling, can not change steel wire extension spring structure symmetry properties, good damping effect by knob bolt.
Summary of the invention:
Goal of the invention: cause the data of collection untrue to solve extraneous vibration, probe and sample bump against problem.
Technological scheme: the utility model provides a kind of compact overall structure, lightweight, convenient to load and transport, cost of production are low, easy leveling, and the damping device that under can meeting normal temperature, the damping leveling of PSTM experiment requires.
A kind of PSTM damping device that the utility model provides comprises framework, crossbeam, steel wire extension spring, object table, bolt, adjustment platform, rubber pad, by steel wire extension spring, adjustment platform is suspended on crossbeam, being placed in by object table by bolt regulates on platform, by knob bolt the two spacing adjustable.Described steel wire extension spring, is characterized in that being suspended on crossbeam, keeps vertically, and lower end hangs and regulates platform; Regulate planform shape to be square or circular, its smooth surface is smooth, is provided with the hole of more than three or three, and bolt passing hole is connected with object table; Object table is provided with the hole of number identical with regulating platform, and passing hole is connected with adjustment platform; Rubber pad is distributed in framework 1 four angles.
Framework material described in the utility model device is stainless steel with holes, for convenience detach and assembling.
Object table described in the utility model device carrys out spacing with the bolt regulating platform by more than three or three, and on bolt, cover has spring.
Rubber pad number described in the utility model device is four, is distributed in four angles of framework respectively, makes whole device reach stable effect.
Beneficial effect: adopt crossbeam to facilitate the extension spring of vertical hanging steel wire, reduces external vibration effectively on the impact of instrument; Adopt and regulate platform and object table, the two spacing can be changed by knob more than three or three bolts, effectively can carry out Levelling operation, avoid directly regulating steel wire extension spring and change steel wire extension spring structure to becoming second nature, affect damping effect.Meet the damping leveling requirement of PSTM experiment under normal temperature completely, there is practicability and creativeness.

Embodiment
Elaborate below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4 pairs of the utility model.
As shown in Fig. 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, a kind of PSTM damping device comprises framework 1, crossbeam 2, steel wire extension spring 3, object table 4, bolt 5, regulates platform 6, rubber pad 7.
Described framework 1 is square, and upper end is provided with two crossbeams 2, by be suspended on crossbeam 2 and four the steel wire extension springs 3 keeping vertical connect and regulate platforms 6.Adjustment platform 6 connects object table 4 by the bolt 5 of more than three and three.
Described object table 4 and adjustment platform 6 are surface plates, PSTM placed by object table 4, by bolt 5, object table 4 is connected as shown in Figure 2 with adjustment platform 6, and regulate object table 4 by knob bolt 5 and regulate the spacing of platform 6 as shown in Figure 4, thus object table 4 is up to the standard.Rubber pad 7 is placed on the bottom of whole device, makes whole device steady.
Working principle of the present utility model is: be placed on by PSTM on the object table 4 of damping device, regulates platform 6 position to fix, and regulates object table 4 and regulates the distance between platform 6, object table 4 is up to the standard by bolt 5.Object table 4, adjustment platform 6 are connected with steel wire extension spring 3, completely cut off the impact of external vibration on PSTM by steel wire extension spring 3.
A kind of PSTM damping device that the utility model device provides has the following advantages: adopt crossbeam to facilitate the extension spring of vertical hanging steel wire, effectively reduces external vibration to the impact of instrument; Adopt and regulate platform and object table, the two spacing can be changed by knob more than three or three bolts, effectively can carry out Levelling operation, avoid directly regulating steel wire extension spring and change steel wire extension spring structure to becoming second nature, affect damping effect.Meet the damping leveling requirement of PSTM experiment under normal temperature completely, there is practicability and creativeness.
The utility model is not only confined to above-mentioned embodiment, and only otherwise under departing from flesh and blood situation of the present utility model, the relevant improvement that the professional workforce being engaged in this field carries out, distortion or replace all will be included within the scope of the utility model.
