Ultrasound electric machine is the inverse piezoelectric effect of utilizing piezoelectric, excites the micro breadth oscillation of stator, and converts vibration to rotor rotatablely move by the rubbing action between stator and rotor, and in ultrasound electric machine, piezoelectric is generally laminar, sticks on stator.In order to guarantee to paste reliably, need under the environment of HTHP, carry out the solidification by cement of a period of time.High pressure refers to very large pressure stator and piezoelectric ceramic piece is fully fitted, this pressure often has 3000N, and the diameter of stator or pressure ceramic sheet only has tens millimeters, if acted directly on above them with weight, pressing steel calculates, the length of weight approximately needs 0.6 meter, and this just proposes extra requirement to the space of high temperature furnace.In actual production process, in order effectively to improve the service efficiency in high temperature furnace space, often adopt the mode of screw press to apply very large active force.Screw press mode is the size on reduced height greatly, but is difficult to accurately hold the size of the power on stator and piezoelectric ceramic piece that acts directly on.If firmly not, cannot guarantee that piezoelectric sticks on stator securely, but exert oneself excessively can cause damage to piezoelectric again.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of piezoelectric ceramic piece and ultrasound electric machine stator solidification by cement pressure is confirmed device, provide accurate pressure that stator and piezoelectric ceramic piece are fully fitted, avoid that amount of force because applying is improper to be damaged piezoelectric ceramic piece or do not reach qualified solidification by cement effect.
A kind of piezoelectric ceramic piece described in the utility model and ultrasound electric machine stator solidification by cement pressure are confirmed device, comprise the balancing weight and the cushion block that are clipped in respectively the upper and lower both sides of workpiece to be machined, there is plug to run through balancing weight and cushion block, one end of plug has a boss, this boss is stuck on cushion block, and clamp nut is spun on the other end of plug.Also have the raised head face laminating of rebound and described plug, power transducer is close to rebound opposite side, and described power sensor setting is on lower shoe, and upper plate is connected to form a frame structure by two root posts and described lower shoe.There is depression bar to be vertically mounted on described upper plate, handle is installed on depression bar.Between described depression bar and balancing weight, be provided with pressure ring, described pressure ring is pressed on balancing weight.Turning handle, the downward traveling priority of depression bar, directly be pressed on pressure ring, the active force producing acts on power transducer by pressure ring, balancing weight, stator, piezoelectric ceramic piece, cushion block, rebound, power transducer can directly be measured the size of this active force, and this active force is identical with the amount of force between stator and piezoelectric ceramic piece.
As the further improvement of technique scheme, the side contacting with plug on described cushion block is provided with groove, and the boss of plug is stuck in the groove of cushion block.
As further improving again of technique scheme, described depression bar is arranged on upper plate centre position.The position contacting with power transducer on described lower shoe is positioned at lower shoe centre position.Can make like this solidification by cement device of the present utility model more stable, measured active force is more accurate.
As the further improvement of technique scheme, the position contacting with power transducer on described lower shoe is provided with groove, and power transducer is positioned at this groove.Power transducer is positioned at groove, can prevent that it from occurring to slide or other change in location in the course of the work, guarantees that the active force recording is more accurate.
A kind of piezoelectric ceramic piece described in the utility model and ultrasound electric machine stator solidification by cement pressure confirm that apparatus structure is simple, the feature that has retained screw press mode compact dimensions, power transducer can record the size of applied active force accurately and fast, the amount of force that assurance applies is suitable, when stator and piezoelectric ceramic piece are fully fitted, can not damage piezoelectric ceramic piece again.
