[0024] A lifting slot 502 is symmetrically provided on one side of the two sets of machine body support plates 2 close to each other, a lifting push block 503 is fixedly installed on the top of the hydraulic rod 501, the top of the lifting push block 503 is fixed at the bottom center of the top plate 7, and lifting sliders 504 slidably connected to the lifting slot 502 are symmetrically fixedly connected on both sides of the lifting push block 503;

[0025] Limiting mechanisms 6 are symmetrically provided inside the two sets of machine body support plates 2 , and the limiting mechanisms 6 are used to clamp and position the workpieces to be assembled inside the tray 8 .

[0026] In this embodiment: when in use, after the tray 8 reaches the blocking position, the lifting mechanism 5 lifts the top plate 7, and the specific steps are as follows: first, the hydraulic rod 501 is controlled to rise, and the hydraulic rod 501 rises to drive the lifting push block 503 to move up, and the lifting push block 503 rises to push the top plate 7 up and drive the lifting slider 504 to move up, pushing the top plate 7 up and driving the tray 8 to rise, and at the same time, the four groups of support push rods 3 move up along the support push cylinder 4 in the vertical direction to assist in the lifting of the top plate 7, and the lifting slider 504 rises to provide a power source for the limiting mechanism 6, and then the workpiece inside the tray 8 is positioned and clamped under the action of the limiting mechanism 6;

[0027] In this way, by setting the body bottom plate 1, the body support plate 2, the support push rod 3, the support push cylinder 4, the lifting mechanism 5, the limit mechanism 6, the top plate 7 and the like to operate in connection, the pallet 8 can be lifted and positioned at the same time with only one power source, which not only saves energy but also reduces the number of operating steps.

[0028] Please refer to Figure 1 to Figure 4 The limiting mechanism 6 includes a receiving groove 607 and a push rod 606. The receiving groove 607 is arranged inside the machine body support plate 2 and above the lifting slide groove 502. An inclined block 605 is arranged inside the receiving groove 607. A push rod 606 is arranged below the inclined block 605. The lower end of the push rod 606 penetrates the inner wall of the receiving groove 607 and fits with the top of the lifting slide block 504, and the upper end of the push rod 606 is fixedly connected to the bottom end of the inclined block 605.

[0029] A movable push rod 601 is provided on one side of the inclined surface of the inclined block 605, and a rotating pressure block 602 and a limiting push cylinder 603 are provided on the side where the body support plates 2 are close to each other. A movable slide groove 608 is opened inside the limiting push cylinder 603.

[0030] In this embodiment: through this structural setting, each part cooperates to realize the positioning and clamping of the workpiece inside the tray 8, and the specific steps are as follows: first, the distance between the moving push rod 601 and the limiting push cylinder 603 is adjusted according to the specifications of the workpiece inside the tray 8, that is, the rotating pressing block 602 is rotated to move and squeeze the limiting push cylinder 603 to a distance that matches the tray 8;

[0031] Afterwards, the lifting mechanism 5 is controlled to operate. During the operation of the lifting mechanism 5, the lifting slider 504 rises and pushes the push rod 606 to move upward. The upward movement of the push rod 606 pushes the inclined block 605 to move upward. The upward movement of the inclined block 605 squeezes the moving push rod 601 to move. The movement of the moving push rod 601 drives the synchronous movement of the limiting push cylinder 603. The movement of the limiting push cylinder 603 realizes the synchronous clamping and positioning of the workpiece inside the tray 8. Afterwards, the lifting mechanism 5 operates, the lifting slider 504 moves downward, the push rod 606 and the inclined block 605 are reset under the action of gravity, and the moving push rod 601 is reset under the action of the reset force of the spring 604. This can be repeated to achieve assembly line operation.

[0032] Please refer to Figure 2-Figure 3 The moving push rod 601 is slidably connected with the limiting push cylinder 603 through the moving slide groove 608. Circular protrusions are connected at both ends of the moving push rod 601, and the diameter of the circular protrusion at one end of the sliding connection between the moving push rod 601 and the limiting push cylinder 603 is slightly larger than the diameter of the limiting push cylinder 603.

[0033] In this embodiment: through this structural setting, the distance between the moving push rod 601 and the limiting push cylinder 603 can be adjusted, which is convenient for the subsequent positioning of trays 8 of different specifications, and the provision of a circular protrusion can prevent the moving push rod 601 and the limiting push cylinder 603 from sliding off and affecting the working operation.

[0034] Please refer to Figure 2 The body support plate 2 is provided with a through hole for the moving push rod 601 to pass through, and a spring 604 is sleeved on the outside of the moving push rod 601. The two ends of the spring 604 are respectively fitted with a circular protrusion at one end of the moving push rod 601 and the inner wall of the body support plate 2. The diameter of the spring 604 is larger than the diameter of the through hole, and the diameter of the circular protrusion at one end of the moving push rod 601 that fits the spring 604 is larger than the diameter of the spring 604.

[0035] In this embodiment: through this structural setting, the size is limited, the parts are prevented from being disjointed, and the normal operation of the structure is ensured, and the spring 604 is provided to provide a reset force for the movable push rod 601, which is convenient for subsequent assembly line operations.

[0036] Please refer to Figure 1 to Figure 5 The outer side of the movable push rod 601 is formed with an external thread, and the inner side of the rotating pressure block 602 is formed with an internal thread threadedly connected to the movable push rod 601. The inner diameter of the rotating pressure block 602 is smaller than the outer diameter of the limiting push cylinder 603, and the rotating pressure block 602 and the limiting push cylinder 603 are in a rotationally connected state.

[0037] In this embodiment: through this structural setting, the rotating pressure block 602 can rotate and move horizontally along the moving push rod 601 to squeeze the limiting push cylinder 603, thereby controlling the distance between the limiting push cylinder 603 and the moving push rod 601, and further realizing the positioning of pallets 8 of different specifications.

[0038] Please refer to Figure 1 A square protrusion is formed on one side of the limiting push cylinder 603 close to each other, and a groove for the square protrusion to pass through is formed on the end surface of the tray 8.

[0039] In this embodiment: through this structural setting, when the limiting push cylinders 603 are close to each other, the square protrusions thereof can pass through the tray 8 and enter into the interior of the tray 8 to clamp the workpieces placed therein.
