Abstract
The present invention discloses a pretension mechanism of a graded wedge for piezoelectric ceramics, which relates to the improvement of a pretension mechanism of piezoelectric ceramics. After adjusted, the existing pretension mechanisms of the piezoelectric ceramics are fixed on a machine body through pins and screws and are reinforced by anti-loose glue, both adjustment and maintenance are inconvenient, and special fixtures are needed at adjustment. The present invention has the technical scheme that a machine body (1) is composed of a platform with a groove (6) at the lower part; a set screw (2) is arranged in a screw hole at the left lower part of the machine body (1); a movable wedge (3) is arranged at the left side in the groove (6) and is adjacent to the set screw (2); piezoelectric ceramic (5) is arranged at the right end in the groove (6); a static wedge (4) is arranged between the movable wedge (3) and the piezoelectric ceramic (5) in the groove (6); the rear part of the set screw (2) is fixedly provided with a flat rounded wing (7); the flat rounded wing (7) at the rear part of the set screw (2) is engaged with a flat groove (8) at the left side edge of the movable wedge (3); the flat rounded wing (7) can be moved in the flat groove (8). When the present invention is adjusted and repaired, or the piezoelectric ceramic is changed, only the set screw needs to be screwed; the present invention has the characteristics of convenient adjustment and maintenance.
Description
Technical field:
The present invention relates to the fine operating means in the precision optics location instrument, particularly the pre-tightening mechanism of piezoelectric ceramic.
Background technology:
After existing piezoelectric ceramic pre-tightening mechanism is adjusted, be connected on the body and reinforced with locking glue again with pin or screw then, prevent the loosening of pre-tightening mechanism, make that so later adjustment maintenance is all very inconvenient, and need special fixture when adjusting, when changing piezoelectric ceramic, also need on body pin hole processing or screw hole again.
Summary of the invention:
The objective of the invention is to develop a kind of piezoelectric ceramic wedge pre-tightening mechanism, it is easy to maintenance that this piezoelectric ceramic wedge pre-tightening mechanism should have adjustment, and do not need the characteristics by any auxiliary tools.The present invention comprises body 1, holding screw 2, piezoelectric ceramic 5, and it also comprises moving wedge 3, quiet wedge 4; Body 1 is made of the platform that a bottom has groove 6, holding screw 2 is arranged in the screw of bottom, body 1 left side, moving wedge 3 is adjacent with the left side wall of groove 6, piezoelectric ceramic 5 is arranged on the right-hand member in the groove 6, quiet wedge 4 is arranged between the moving wedge 3 and piezoelectric ceramic 5 in the groove 6, the rear portion of holding screw 2 is fixed with the flat circle wing 7, and the flat circle wing 7 at holding screw 2 rear portions matches with the sector 8 on the limit, moving wedge 3 left side, and the flat circle wing 7 can be movable in sector 8.The present invention adjust, maintenance or when changing piezoelectric ceramic, only need turn holding screw can finish, have and adjust easy to maintenancely, do not need by any auxiliary tools time saving and energy saving advantage.
Description of drawings:
Fig. 1 is an overall structure schematic diagram of the present invention.
Embodiment:
Embodiment one: present embodiment is made up of body 1, holding screw 2, piezoelectric ceramic 5, moving wedge 3, quiet wedge 4; Body 1 is made of the platform that a bottom has groove 6, holding screw 2 is arranged in the screw of bottom, body 1 left side, moving wedge 3 is adjacent with the left side wall of groove 6, piezoelectric ceramic 5 is arranged on the right-hand member in the groove 6, quiet wedge 4 is arranged between the moving wedge 3 and piezoelectric ceramic 5 in the groove 6, the rear portion of holding screw 2 is fixed with the flat circle wing 7, and the flat circle wing 7 at holding screw 2 rear portions matches with the sector 8 on the limit, moving wedge 3 left side, and the flat circle wing 7 can be movable in sector 8.The width of moving wedge 3 lower ends is greater than the width of upper end, and the width of quiet wedge 4 lower ends is less than the width of upper end.Moving wedge 3 is identical with the angle of inclination on quiet wedge 4 inclined-planes.The width that transverse width in the groove 6 adds quiet wedge 4 upper ends less than the width of moving wedge 3 upper ends add piezoelectric ceramic 5 length and.The up and down distance of moving wedge 3 is less than the up and down distance of holding screw 2 in screw.
The flat circle wing 7 of holding screw 2 drives moving wedge 3 and moves in the vertical direction, and under the effect on inclined-plane, promote quiet wedge 4 along continuous straight runs and move, thus the pretightning force of adjustment piezoelectric ceramic.
