[0020] The beneficial effects of the present invention are as follows:
[0021] 1. The present invention is provided with a quick-release component and a connection reset component. Through the fixture on the workbench, the universal joint ring of the aero-engine is fixed on the workbench, and the cross shaft on the universal joint ring of the aero-engine is positioned directly below the hammer head. Then, the servo motor is started, and the output shaft of the servo motor drives the rotating disk to rotate, causing the moving plate to drive the connecting plate, damper, fixed plate, and return spring A to move upward through the elastic component. The sliding block slides upward in the sliding groove, the guiding block slides upward in the guiding groove, and the reset spring is stretched under force until the top surface of the sliding block contacts the inner top wall of the sliding groove. At this time, under the action of the elastic component, the reset spring is no longer under force and begins to contract, causing the sliding block to slide downward in the sliding groove, the guiding block to slide downward in the guiding groove, and the moving plate to drive the connecting plate, damper, fixed plate, and return spring A to move downward, enabling the hammer head to contact the cross shaft on the universal joint ring of the aero-engine and strike the cross shaft. During the striking process, the damper can provide resistance and buffering effects to adapt to the striking position of the cross shaft, and the return spring A can return the damper to its original position. Moreover, under the elastic force of the reset spring, the hammer head continuously strikes the cross shaft. Compared with the prior art, the structure of the present invention is reasonably designed. Driven by the servo motor and under the action of the connection reset component, the hammer head can continuously strike the universal joint ring of the aero-engine, with relatively high disassembly and assembly efficiency, so as to achieve rapid disassembly and assembly of the universal joint ring of the aero-engine, and moreover, the degree of automation is relatively high.
[0022] 2. The present invention is provided with an elastic component. When the rotating disk rotates, the abutting block presses against the inner wall of the movable groove. Since the elastic strength of the reset spring is less than that of the return spring B, the moving plate drives the connecting plate, damper, fixed plate, and return spring A to move upward, causing the abutting block to slide in the movable groove until the top surface of the sliding block contacts the inner top wall of the sliding groove. At this time, the circumferential surface of the abutting block presses against the inner wall of the movable groove, causing the abutting block to slide in the abutting groove, and the return spring B is compressed under force until the abutting block no longer contacts the moving plate. At this time, under the elastic force of the reset spring, the hammer head continuously strikes the cross shaft. When the abutting block no longer contacts the moving plate, under the elastic force of the return spring B, the abutting block slides back to its original position. Moreover, during the rotation of the rotating disk, the abutting block contacts the top surface of the moving plate, enabling the abutting block to gradually eliminate the elastic force of the reset spring until the bottom surface of the sliding block contacts the inner bottom wall of the sliding groove. At this time, the circumferential surface of the abutting block presses against the moving plate, causing the abutting block to slide in the abutting groove, and the return spring B is compressed under force until the abutting block rotates to the lowest end. At this time, under the elastic force of the return spring B, the abutting block contacts the inner wall of the movable groove.
[0023] 3. In the present invention, by providing a limit component, according to the size of the universal joint ring of the aero-engine to be disassembled and assembled as needed, rotate the screw rod so that the screw rod is threadedly connected to the fixed plate, causing the spherical surface of the sphere to press against the inclined surface of the wedge-shaped groove, enabling the positioning block to slide within the receiving groove and the positioning groove, causing the return spring C to contract under force until the spherical surface of the sphere contacts the inner bottom wall of the wedge-shaped groove. At this time, the positioning block moves out of the positioning groove. Then, move the hammer head so that the limiting block slides within the limiting groove until the limiting block moves out of the limiting groove. Then, select a hammer head of a suitable size, insert the limiting block into the limiting groove, and make the side surface of the limiting block contact the inner side wall of the limiting groove. Subsequently, rotate the screw rod in the reverse direction so that the screw rod is threadedly connected to the fixed plate. Under the elastic force of the return spring C, the positioning block will slide reversely within the receiving groove and the positioning groove until the side surface of the sphere contacts the inner top wall of the receiving groove. At this time, the positioning block is inserted into the positioning groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In the present invention, by providing the quick-release component 2 and the connecting and resetting component 4, the universal joint ring of the aero-engine is fixed on the workbench 101 through the fixture on the workbench 101, and the cross shaft on the universal joint ring of the aero-engine is positioned directly below the hammer head 102.

At this time, the positioning block 504 is inserted into the positioning groove 505;Next, fix the aero-engine universal joint ring on the workbench 101 through the fixture on the workbench 101, and make the cross shaft on the aero-engine universal joint ring directly below the hammer head 102. Then, start the servo motor 202, so that the output shaft of the servo motor 202 drives the rotating disk 203 to rotate, causing the abutting block 302 to squeeze the inner wall of the movable slot 304. Since the elastic strength of the return spring 403 is less than that of the return spring B 303, the moving plate 204 will drive the connecting plate 205, the damper 206, the fixing plate 207 and the return spring A 208 to move upward, causing the abutting block 302 to slide in the movable slot 304, causing the sliding block 402 to slide upward in the sliding slot 401, causing the guiding block 405 to slide upward in the guiding slot 404, and causing the return spring 403 to be stretched until the top surface of the sliding block 402 contacts the inner top wall of the sliding slot 401. At this time, the circumferential surface of the abutting block 302 will squeeze the inner wall of the movable slot 304, causing the abutting block 302 to slide in the abutting slot 301, causing the return spring B 303 to be compressed until the abutting block 302 no longer contacts the moving plate 204. At this time, the return spring 403 is no longer stressed and begins to contract, causing the sliding block 402 to slide downward in the sliding slot 401, causing the guiding block 405 to slide downward in the guiding slot 404, causing the moving plate 204 to drive the connecting plate 205, the damper 206, the fixing plate 207 and the return spring A 208 to move downward, so that the hammer head 102 can contact the cross shaft on the aero-engine universal joint ring and strike the cross shaft. During the striking process, the damper 206 can provide resistance and buffering effect to adapt to the striking position of the cross shaft, and the return spring A 208 can make the damper 206 return to its original position. And under the elastic force of the return spring 403, the hammer head 102 will continuously strike the cross shaft. When the abutting block 302 no longer contacts the moving plate 204, under the elastic force of the return spring B 303, the abutting block 302 will slide back to its original position. And during the rotation of the rotating disk 203, the abutting block 302 will contact the top surface of the moving plate 204, enabling the abutting block 302 to gradually eliminate the elastic force of the return spring 403 until the bottom surface of the sliding block 402 contacts the inner bottom wall of the sliding slot 401. At this time, the circumferential surface of the abutting block 302 will squeeze the moving plate 204, causing the abutting block 302 to slide in the abutting slot 301, causing the return spring B 303 to be compressed until the abutting block 302 rotates to the lowest end. At this time, under the elastic force of the return spring B 303, the abutting block 302 will contact the inner wall of the movable slot 304, causing the abutting block 302 to squeeze the inner wall of the movable slot 304, causing the moving plate 204 to drive the connecting plate 205, the damper 206, the fixing plate 207 and the return spring A 208 to move upward, and so on until after the disassembly and assembly of the aero-engine universal joint ring is completed, control the servo motor 202 so that the output shaft of the servo motor 202 no longer rotates, and then the disassembled and assembled aero-engine universal joint ring can be removed from the workbench 101.;
