[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0029] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0030] A high-strength lifting device for a metal pressing equipment, as Figure 1-7As shown in the figure, it includes a bottom plate 100. A lifting assembly 200 is provided at the top end of the bottom plate 100. And a lifting seat 110 is provided directly above the bottom plate 100. A clamping assembly 300 is provided at the top end of the lifting seat 110. And a conveying assembly 400 is slidably connected inside the lifting seat 110;

[0031] The lifting assembly 200 includes a biaxial motor 210 fixed to the top end of the bottom plate 100. The output ends of the biaxial motor 210 are fixedly connected with threaded lead screws 220. A moving plate 230 is rotatably connected to the surface of the threaded lead screws 220. A piston rod 240 is welded to the upper side of one side of the moving plate 230. A piston cylinder 250 is slidably connected to the surface of the piston rod 240. Two groups of connecting pipes 260 are fixed to one side of the piston cylinder 250. A hydraulic cylinder 270 is provided at the end of the connecting pipe 260 away from the piston cylinder 250. The clamping assembly 300 includes a corrugated pipe 310 connected to one side of the hydraulic cylinder 270. A fixed pipe 320 is connected to the side of the corrugated pipe 310 away from the hydraulic cylinder 270. A fixed seat 330 is connected to the end of the fixed pipe 320 away from the corrugated pipe 310. A moving block 340 is slidably connected inside the fixed seat 330. A square plate 350 is welded to the end of the moving block 340 away from the fixed seat 330. A number of grooves 351 are formed inside the square plate 350. Springs 360 are provided inside the grooves 351. A limiting plate 370 is provided on one side of the spring 360. A ball head rod 380 is welded to the side of the limiting plate 370 away from the spring 360.

[0032] The staff places the metal part 120 on the lifting seat 110. Then the biaxial motor 210 is started to drive the threaded lead screws 220 on both sides to rotate, so that the threaded lead screws 220 drive the moving plate 230 to move, and the moving plate 230 drives the piston rod 240 to squeeze the hydraulic oil inside the piston cylinder 250, so that the hydraulic oil enters the hydraulic cylinder 270 through the connecting pipe 260 under the action of pressure. Furthermore, the hydraulic cylinder 270 drives the lifting seat 110 to rise, which is convenient for subsequent press-fitting of metal parts 120 of different sizes, effectively improving the applicability of the device. When it rises to the required height, the hydraulic oil enters the fixed pipe 320 through the corrugated pipe 310 through the one-way valve, and then enters the fixed seat 330 from the fixed pipe 320. Furthermore, the moving block 340 drives the square plate 350 to move, and the square plate 350 drives the ball head rod 380 to move towards the side of the metal part 120 until the ball head rod 380 fits on the surface of the metal part 120. The continuous movement of the square plate 350 causes the ball head rod 380 to be squeezed and compress the spring 360, thereby realizing the clamping and fixing of the metal part 120. The multi-group ball head rods 380 can contact and fix the metal part 120 in multiple directions. Therefore, it can effectively prevent the metal part 120 from shaking or displacing during the processing, thus ensuring the smooth progress of the processing. At the same time, it can also adapt to metal parts 120 of different shapes and sizes, thereby improving the processing efficiency and adaptability.

[0033] Please refer particularly to Figures 3 to 5 , the top end of the hydraulic cylinder 270 is fixedly connected to the bottom end of the lifting seat 110. A metal part 120 is placed on the top end of the lifting seat 110. A connecting plate 221 is rotated at one end of the threaded lead screw 220 away from the dual-shaft motor 210. The bottom end of the connecting plate 221 is fixedly connected to the bottom plate 100.

[0034] The lifting seat 110 can be lifted by the hydraulic cylinder 270, which is convenient for press-fitting the metal part 120. The connecting plate 221 can better enhance the stability of the threaded lead screw 220 during rotation.

[0035] Please refer particularly to Figure 2 and Figure 3 , one-way valves are provided at the connections of the connecting pipe 260, the bellows 310 and the hydraulic cylinder 270. One end of the fixed pipe 320 penetrates through the lifting seat 110. Four groups of fixed seats 330 are provided, and the four groups of fixed seats 330 are circumferentially arrayed on the top end of the lifting seat 110.

[0036] The metal part 120 can be effectively clamped and fixed by setting the one-way valve. The clamping effect can be further enhanced by setting the four groups of fixed seats 330.

[0037] Please refer particularly to Figure 1 , Figure 6 and Figure 7 , the conveying assembly 400 includes a rack 410 fixedly connected to the top end of the bottom plate 100. A ratchet gear 420 meshing with the rack 410 is provided on one side of the rack 410. A first long shaft 430 is fixedly connected to the center of the ratchet gear 420. A first pulley 440 is fixedly connected to the surface of the first long shaft 430. A belt 450 is rotatably connected to the surface of the first pulley 440. A second pulley 460 is rotatably connected to the inner wall of the belt 450 on the side away from the first pulley 440. A second long shaft 470 is fixedly connected to the center of the second pulley 460. Rotating plates 480 are welded to the ends of the first long shaft 430 and the second long shaft 470 away from the ratchet gear 420. A round shaft 490 is fixedly connected to the lower end of the side of the rotating plate 480 away from the first long shaft 430. One end of the round shaft 490 away from the rotating plate 480 is rotatably connected to a vertical plate 4910. A horizontal plate 4920 is welded to the top end of the vertical plate 4910. The horizontal plate 4920 is slidably connected to the lifting seat 110. The horizontal plate 4920 and the lifting seat 110 are on the same horizontal plane, and the top end of the horizontal plate 4920 is in contact with the metal part 120.

[0038] After the metal part 120 is press-fitted, lower the lifting seat 110. The lifting seat 110 drives the cross plate 4920 and the vertical plate 4910 to descend synchronously. At the same time, the clamping assembly 300 releases the fixation of the metal part 120. When it descends a certain distance, the ratchet gear 420 meshes with the rack 410, thereby driving the ratchet gear 420 to rotate. The ratchet gear 420 drives the first long shaft 430 to rotate. The first long shaft 430 drives the second long shaft 470 to rotate synchronously through the first pulley 440, the belt 450 and the second pulley 460. The first long shaft 430 and the second long shaft 470 drive the rotating plate 480 to rotate synchronously. The rotating plate 480 drives the vertical plate 4910 and the cross plate 4920 to make a reciprocating circular motion with the first long shaft 430 and the second long shaft 470 as the centers, thereby driving the press-fitted metal part 120 to move to one side, realizing the conveyance of the press-fitted metal part 120. At the same time, it can also convey the unpress-fitted metal part 120 to the central position of the lifting seat 110, effectively improving the work efficiency of the staff. At the same time, it also avoids the staff from taking it in the center of the device, and better improves the work safety.

[0039] During use, start the double-shaft motor 210 to drive the threaded lead screws 220 on both sides to rotate, so that the hydraulic oil enters the hydraulic cylinder 270 through the connecting pipe 260 under the action of pressure. Then the hydraulic cylinder 270 drives the lifting seat 110 to rise, facilitating the subsequent press-fitting of metal parts 120 of different sizes, effectively improving the applicability of the device. When it rises to the required height, the hydraulic oil enters the fixed seat 330 through the one-way valve, so that the ball head rod 380 fits on the surface of the metal part 120. The continuous movement of the square plate 350 causes the ball head rod 380 to be squeezed and compress the spring 360, thereby realizing the clamping and fixation of the metal part 120. Through multiple groups of ball head rods 380, the metal part 120 can be contacted and fixed in multiple directions. Therefore, it can effectively prevent the metal part 120 from shaking or displacing during the processing process, thus ensuring the smooth progress of the processing process. At the same time, it can also adapt to metal parts 120 of different shapes and sizes, thereby improving the processing efficiency and adaptability. After the metal part 120 is press-fitted, lower the lifting seat 110 to release the fixation of the metal part 120. The ratchet gear 420 rotates, and the rotating plate 480 drives the vertical plate 4910 and the cross plate 4920 to make a reciprocating circular motion with the first long shaft 430 and the second long shaft 470 as the centers, thereby driving the press-fitted metal part 120 to move to one side, realizing the conveyance of the press-fitted metal part 120. At the same time, it can also convey the unpress-fitted metal part 120 to the central position of the lifting seat 110, effectively improving the work efficiency of the staff. At the same time, it also avoids the staff from taking it in the center of the device, and better improves the work safety. The parts not involved in this device are the same as or can adopt the existing technology to implement.
