Abstract
The invented pretension mechanism includes the body with the flute, the tight screw, the movable wedge, the static wedge and the piezodielectric ceramics. The tight screw is in the bolthole located at the lower left part of the body. The movable wedge is positioned at the left side of the flute and adjacent to the tight screw. The piezodielectric ceramics is positioned at the right side of the flute. The static wedge is located between the movable wedge and the piezodielectric ceramics. In the rear part of the tight screw, there is the fixed flat rounded wing, which is matched to the flat groove on the side of the movable wedge. In the invention, twisting the tight screw can replace the piezodielectric ceramics so the maintaining work is easy. In the prior art, the pin and the glue are used to lock the piezodielectric ceramics so it is cumbersome to do the 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 arranged on left end in the groove 6 and adjacent with holding screw 2, 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, 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 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 arranged on left end in the groove 6 and adjacent with holding screw 2, 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, 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.
