[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1-4 As shown, a heavy workpiece loading and unloading handling device includes a frame 1 and a mounting assembly 2. The mounting assembly 2 is slidably connected inside the frame 1. A slidable and retractable bearing plate 3 is provided inside the mounting assembly 2. A U-shaped groove 31 is provided in the middle of the bearing plate 3. Sliding grooves 32 are symmetrically arranged inside the bearing plate 3. One end of the sliding groove 32 is connected to the U-shaped groove 31. A workpiece unloading assembly 4 for supporting the workpiece is slidably connected inside the sliding groove 32.

[0021] According to the above structure, when in use, the workpiece is placed inside the U-shaped groove 31, the feeding assembly 4 supports the workpiece, and after the workpiece is placed, the mounting assembly 2 is lifted upward, thereby lifting the bearing plate 3, the feeding assembly 4 and the workpiece together. After being lifted to the corresponding height, the bearing plate 3 is pushed forward to the top of the workpiece seat of the machine tool, and then the workpiece is lowered onto the workpiece seat through the feeding assembly 4.

[0022] like Figure 2 and 3 As shown, the frame 1 includes a square frame 11, inside which are arranged four sliding guide rollers 12 arranged in a rectangular array, and at the top of the square frame 11 are four first electro-hydraulic columns 13 arranged in a rectangular array.

[0023] According to the above structure, when the mounting component 2 is lifted, the mounting component 2 moves up and down along the sliding guide roller 12, which improves the stability of the mounting component 2 during lifting.

[0024] like Figure 4As shown, the mounting assembly 2 includes a U-shaped plate 21 slidably connected inside the frame 11. The surface of the U-shaped plate 21 is provided with four through holes 22 arranged in a rectangular array, which penetrate the U-shaped plate 21. Four sliding guide rollers 12 are slidably connected inside the four through holes 22. A second electro-hydraulic column 23 is provided in the middle of one end of the U-shaped plate 21. One end of the second electro-hydraulic column 23 is fixedly connected to one end of the bearing plate 3. The top and bottom ends of the inner wall of the U-shaped plate 21 are symmetrically provided with mounting grooves 24. Rotary rollers 25 are rotatably connected inside the mounting grooves 24. The top and bottom ends of the mounting assembly 2 are symmetrically provided with guide grooves 35, and the four guide grooves 35 are respectively provided with the four mounting grooves 24.

[0025] According to the above structure, when lifting the U-shaped plate 21, the U-shaped plate 21 is lifted by retracting the first electro-hydraulic column 13. When the U-shaped plate 21 is raised to the corresponding height, the bearing plate 3 is pushed outward by extending the second electro-hydraulic column 23, thereby driving the workpiece to move. When the bearing plate 3 moves, the roller 25 rotates, reducing the friction between the bearing plate 3 and the inner wall of the U-shaped plate 21, and improving the smoothness of the extension and retraction of the bearing plate 3.

[0026] like Figure 4 As shown, the feeding assembly 4 includes a semi-circular plate 41 slidably connected inside the chute 32. One side of the top of the semi-circular plate 41 has a sloping structure. A stop block 42 is fixedly connected to one end of the semi-circular plate 41. Push-pull rods 44 are symmetrically arranged on the side wall of the semi-circular plate 41. A connecting plate 45 is fixedly connected between one end of the two push-pull rods 44. A third electro-hydraulic column 34 is provided on both sides of the bearing plate 3. One end of the third electro-hydraulic column 34 is fixedly connected to one end of the corresponding connecting plate 45.

[0027] According to the above structure, when the workpiece moves to the top of the machine tool base, the connecting plate 45 is pushed to move by extending the third electric hydraulic column 34, which in turn drives the semi-circular plate 41 to move outward, so that the bottom end of the U-shaped groove 31 opens, and the workpiece is lowered onto the machine tool base. The stop block 42 can block the workpiece when it moves up and down, improving the stability of the workpiece. One side of the top of the semi-circular plate 41 is sloping, which can make the workpiece descend slowly.

[0028] like Figure 4 As shown, in order to improve the stability of the semicircular plate 41 during movement and the load-bearing capacity of the semicircular plate 41, the bottom end of the inner wall of the slide groove 32 is provided with equally spaced trapezoidal rails 33, and the bottom end of the semicircular plate 41 is provided with equally spaced trapezoidal grooves 43, with the trapezoidal rails 33 slidably connected inside the corresponding trapezoidal grooves 43.

[0029] The working principle of this utility model is as follows: During use, the workpiece is placed inside the U-shaped groove 31. The feeding assembly 4 supports the workpiece. After the workpiece is placed, the mounting assembly 2 is lifted upwards, thereby lifting the bearing plate 3, the feeding assembly 4, and the workpiece together. After being lifted to the corresponding height, the bearing plate 3 is pushed forward to above the workpiece seat of the machine tool. Then, the workpiece is lowered onto the workpiece seat via the feeding assembly 4. When lifting the mounting assembly 2, the mounting assembly 2 moves up and down along the sliding guide roller 12, improving the stability of the mounting assembly 2 during lifting. When lifting the U-shaped plate 21, the first electro-hydraulic column 13 is retracted to lift the U-shaped plate 21 upwards. When the U-shaped plate 21 rises to the corresponding height... After reaching the desired height, the second electro-hydraulic column 23 extends to push the bearing plate 3 outward, thereby moving the workpiece. When the bearing plate 3 moves, the roller 25 rotates, reducing the friction between the bearing plate 3 and the inner wall of the U-shaped plate 21, and improving the smoothness of the bearing plate 3's extension and retraction. When the workpiece moves above the machine tool base, the third electro-hydraulic column 34 extends to push the connecting plate 45 to move, thereby moving the semi-circular plate 41 outward, opening the bottom end of the U-shaped groove 31, and allowing the workpiece to descend onto the machine tool base. The stop block 42 can block the workpiece when it moves up and down, improving the stability of the workpiece. One side of the top of the semi-circular plate 41 is sloped, which allows the workpiece to descend slowly.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
