Each pneumatic drive device is connected to a corresponding swing arm to drive the swing arm to rotate and control the clamping plate to clamp and fix the inclined side of the aluminum ingot.

[0006] As a preferred embodiment of this utility model, the pneumatic drive device is a cylinder, the fixed end of the cylinder is mounted on the support frame, and the telescopic end of the cylinder is connected to the upper end of the swing arm.

[0007] As a preferred embodiment of this utility model, a safety positioning device is provided at the lower end of the support frame. The safety positioning device includes a positioning rod, a spring, and a positioning plate.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 1 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] Please see Figure 1-2 This utility model provides a technical solution: a pneumatic stacking fixture for aluminum ingots, including a support frame 1, a clamping mechanism 2 and a pneumatic drive device 3; The support frame 1, as the carrier of the entire fixture, is made of high-strength alloy plate, which has the characteristics of good rigidity and high strength. The upper end of the support frame 1 is connected to the robotic arm or robotic hand through the connector 4. The connector 4 and the robotic arm or robotic hand are connected by bolts. The robotic arm or robotic hand drives the entire fixture to move above the aluminum ingot to be clamped. There are three clamping mechanisms 2, which are arranged side by side on the support frame 1. Each clamping mechanism 2 includes a swing arm 21 and a clamping plate 22. There are two swing arms 21, which are symmetrically arranged at both ends of the upper surface of the support frame 1. The middle position of the swing arm 21 is rotatably connected to the support frame 1. The clamping plate 22 is fixed to the lower end of the swing arm 21. The clamping plate 22 is made of heat-resistant material and can adapt to aluminum ingots of different sizes to ensure stable and reliable clamping. The pneumatic drive device 3 is installed on the upper end of the support frame 1. Each pneumatic drive device 3 is connected to a corresponding swing arm 21 to drive the swing arm 21 to rotate and control the clamping plate 22 to clamp and fix the inclined side of the aluminum ingot. The installed cylinder is a synchronous cylinder, which ensures that the three clamping mechanisms 2 move synchronously through a precise air circuit. At the same time, it is equipped with an air pressure adjustment component to suit aluminum ingots of different weights.

[0014] Furthermore, the pneumatic drive device 3 is a cylinder, with the fixed end of the cylinder mounted on the support frame 1, and the telescopic end of the cylinder hinged to the upper end of the swing arm 21.

[0015] Furthermore, to prevent the high-temperature aluminum ingot from damaging the support frame 1, a safety positioning device 6 is provided at the lower end of the support frame 1. The safety positioning device 6 includes a positioning rod 61, a spring 62, and a positioning plate 63. The positioning plate 63 is fixed at the lower end of the positioning rod 61, and the upper end of the positioning rod 61 passes through the support frame 1. A spring 62 is provided between the positioning plate 63 and the lower surface of the support frame 1. The spring 62 is sleeved on the outer side of the positioning rod 61. The positioning plate 63, the positioning rod 61, and the spring 62 are all made of heat-resistant material. When the robotic arm drives the fixture to contact the upper surface of the aluminum ingot, the positioning rod 61 is lifted up under the action of the spring 62. After setting the absolute coordinates of the robotic arm, the downward pressing position of the robotic arm is fixed, thereby maintaining a safe distance between the aluminum ingot and the support frame 1, protecting the support frame 1, and at the same time playing a positioning role for the aluminum ingot.

[0016] Furthermore, in order to ensure the linearity of the movement of the positioning rod 61, a guide sleeve 5 is provided on the support frame 1. The positioning rod 61 passes through the guide sleeve 5 to ensure the rapid and accurate alignment of the aluminum ingot and the stacking station.

[0017] In use: The support frame 1 is connected to the robot or gantry robot arm via the connector 4. When the fixture moves above the aluminum ingot, the positioning plate 63 first engages with the positioning hole of the aluminum ingot for coarse positioning. The pneumatic drive device 3 simultaneously drives the clamping mechanism 2 of the three workstations to move. Under the positioning of the spring 62 of the safety positioning device 6, the three clamping plates 22 accurately clamp the three aluminum ingots, lift them and move them to the stacking position. The pneumatic system is released, and the aluminum ingots are accurately placed in the designated position. Throughout the process, the clamping and release of the three aluminum ingots are completely synchronized.
