[0026] The preferred specific embodiments for implementing the present utility model are described in detail below, and a clear and complete description is made in conjunction with the accompanying drawings.

[0027] Please refer to Figures 1-6 , the present utility model provides a lifting fixture device for piezoelectric ceramic specimens.

[0028] Piezoelectric ceramics are a kind of functional ceramic materials that can convert mechanical energy and electrical energy into each other, and are widely used in high-tech fields such as mobile communication, satellite broadcasting, electronic devices, instruments, biology, and aerospace, becoming an indispensable key modern material and component. A number of steel sheets with piezoelectric ceramic sheets pasted thereon are positioned on a backing plate, and a flat pressing plate is used to apply overall pressure to each piezoelectric ceramic microporous atomization sheet until the adhesive is cured. Although this method is relatively simple, since the steel sheets will undergo varying degrees of deformation during the process of machining micropores, and the thicknesses of the formed piezoelectric ceramic microporous atomization sheets are different after pasting, it is difficult to ensure that each product has good bonding and fitting performance during the curing process. Therefore, it needs to be improved, including a base 100 and a support frame 200 fixed to the top end of the base 100. A clamping device 300 for pressing the piezoelectric ceramic specimen is provided below the frame body of the support frame 200. A lifting device 400 for driving the clamping device 300 to move up and down is provided at the bottom end of the frame body of the support frame 200. A support device 500 for cooperating with the clamping device 300 to press and bond the piezoelectric ceramic specimen is provided at the top end of the base 100;

[0029] The clamping device 300 includes a connection component 350 for moving up and down. A top pressure rod 360 for cooperating with the clamping device 300 to press and bond the piezoelectric ceramic specimen penetrates through the plate body of the connection component 350, and the top pressure rods 360 are linearly arrayed on the plate body of the connection component 350, so as to quickly bond a number of steel sheets of multiple piezoelectric ceramic sheets; a fixing plate 310 for adjusting the height of the multiple top pressure rods 360 is welded to the top ends of the multiple top pressure rods 360. A support column 320 for supporting the fixing plate 310 is provided at the bottom end of the fixing plate 310, and the support column 320 can be replaced accordingly according to the height of the multiple top pressure rods 360; a screw rod one 330 for penetrating through the fixing plate 310 and adjusting the top pressure rods 360 is provided at the top end of the connection component 350. An adjusting nut 340 for fixing the fixing plate 310 is threadedly connected to the rod body of the screw rod one 330. Thus, when it is necessary to adjust the height of the multiple top pressure rods 360, the corresponding adjustment of the multiple top pressure rods 360 can be realized by the threaded connection of the adjusting nut 340 on the rod body of the screw rod one 330;

[0030] The connecting component 350 includes a connecting plate 351 for supporting the pressing rod 360. At the left and right ends of the connecting plate 351, moving plates 352 for driving the connecting plate 351 to move up and down are fixedly installed. And the moving plate 352 on the right side of the connecting plate 351 is threadedly connected to the second screw rod 450. Thus, when the second screw rod 450 rotates, the connecting plate 351 can be controlled to be adjusted up and down, and then a plurality of pressing rods 360 can be driven to bond several steel sheets of a plurality of piezoelectric ceramic sheets on the supporting device.

[0031] The lifting device 400 includes a second screw rod 450 that is threadedly connected to the moving plate 352. And the top end of the second screw rod 450 is connected to the frame body of the support frame 200 through a bearing, and the bottom end of the second screw rod 450 is connected to the seat body of the base 100 through a bearing, which facilitates the rotation of the second screw rod 450. A second bevel gear 440 for driving the second screw rod 450 to rotate is arranged on the rod body of the second screw rod 450. And the second bevel gear 440 is installed on the rod body of the second screw rod 450 through a key connection. Moreover, the second bevel gear 440 is located at the bottom of the rod body of the second screw rod 450. In front of the second bevel gear 440, a first bevel gear 430 for meshing with the second screw rod 450 is arranged.

[0032] In the middle of the front side of the wheel body of the first bevel gear 430, a rotating shaft 420 for driving the first bevel gear 430 to rotate is inserted. And the first bevel gear 430 is installed on the shaft body of the rotating shaft 420 through a key connection. Thus, when the rotating shaft 420 rotates, under the meshing connection of the first bevel gear 430 and the second bevel gear 440, the second screw rod 450 can be synchronously driven to rotate, so that the moving plate 352 can be controlled to drive the pressing rod 360 to move up and down. Furthermore, several steel sheets of a plurality of piezoelectric ceramic sheets can be bonded. A hand wheel 410 for driving the rotating shaft 420 to rotate is fixedly installed on the front side of the rotating shaft 420. A guide rod 460 for guiding the moving plate 352 on the left side of the connecting plate 325 is fixedly installed at the top end of the base 100. Thus, when the operator drives the rotating shaft 420 to rotate through the hand wheel 410, under the meshing connection of the first bevel gear 430 and the second bevel gear 440, the second screw rod 450 can be synchronously driven to rotate following the rotating shaft 420. Furthermore, a plurality of pressing rods 360 on the moving plate 352 can be driven to move down, and several piezoelectric ceramic sheets and several steel sheets can be bonded.

[0033] The support device 500 includes a support plate 510 welded to the top end of the base 100. Positioning counterbores 520 for placing piezoelectric ceramic specimens are formed in the plate body of the support plate 510, and there are several positioning counterbores 520. The several positioning counterbores 520 are linearly arrayed on the plate body of the support plate 510. A bottom plate 530 for quickly removing the pressed piezoelectric ceramic specimens is arranged in the plate body of the support plate 510, and the bottom plate 530 can move back and forth in the support plate 510. A sliding groove 511 for restricting the bottom plate 530 is formed in the plate body of the support plate 510. Limiting blocks 531 for sliding in the groove of the sliding groove 511 are fixedly installed on the left and right sides of the plate body of the bottom plate 530. Thus, when it is necessary to bond multiple piezoelectric ceramic sheets and several steel sheets, when the handwheel 410 drives the rotation of the rotating shaft 420, under the meshing connection of the first bevel gear 430 and the second bevel gear 440, the second screw rod 450 can be synchronously driven to rotate following the rotating shaft 420, and the moving plate 352 can be driven to move downward, and then multiple pressing rods 360 can be driven to press the multiple positioning counterbores 520 for placing multiple piezoelectric ceramic sheets and several steel sheets. After pressing the piezoelectric ceramic sheets, the moving plate 352 can be synchronously driven to move upward, and then by pulling out the driving bottom plate 530 through the handle welded to the front end of the bottom plate 530, multiple piezoelectric ceramic sheets can be quickly removed.
