[0017] As Figure 1 shown, a fully automatic clamping mechanism for a part provided by the present utility model includes a bottom plate 1, two placing tables 2 are connected to the bottom plate 1, and parts are placed on the placing tables 2.

[0018] On one side of each placing table 2, a rotating pressing member 3 is connected. The rotating pressing member 3 includes a first cylinder 3.1. A first installation through groove is provided on the bottom plate 1, and the first cylinder 3.1 is connected in the first installation through groove. A rotating plate 3.2 is hinged to the piston rod of the first cylinder 3.1. One side below the rotating plate 3.2 is hinged to the upper side of the outer shell of the first cylinder 3.1, that is, a fixing block is connected to the upper side of the outer shell of the cylinder 3.1. A first rotating hole is provided on the fixing block, and a first shaft is inserted into the first rotating hole. Vertical plates are connected to both sides of the first shaft. A second shaft is connected to the upper side between the two vertical plates. A second rotating hole is provided on the rotating plate 3.2, and the second shaft is inserted into the second rotating hole. A second pressing plate 3.3 is connected to one side of the rotating plate 3.2. The first cylinder 3.1 drives the rotating plate 3.2 to rotate, so that the rotating plate 3.2 drives the second pressing plate 3.3 to press or loosen the parts.

[0019] A rotating pressing member 4 is provided between the two placing tables 2. The rotating pressing member 4 includes a first rotating cylinder 4.1. A second installation through groove is provided on the bottom plate 1, and the first rotating cylinder 4.1 is fixed in the second installation through groove. A T-shaped plate 4.2 is connected to the piston rod of the first rotating cylinder 4.1. First pressing plates 4.3 are connected to both sides of the T-shaped plate 4.2. When the first rotating cylinder 4.1 drives the two first pressing plates 4.3 to descend, it will drive the two first pressing plates 4.3 to rotate at the same time, so that the first pressing plates 4.3 are located above the corresponding placing tables 2, enabling the first pressing plates 4.3 to press the parts on the placing tables 2. When the first rotating cylinder 4.1 drives the first pressing plates 4.3 to rise, it will drive the first pressing plates 4.3 away from the corresponding placing tables 2, facilitating the operator to place the parts on the placing tables 2.

[0020] Moreover, by driving the two first pressing plates 4.3 to move downward while rotating through the first rotating cylinder 4.1, two parts can be pressed simultaneously.

[0021] On the periphery of each placing table 2, first positioning members 5 and second positioning members 6 are respectively connected in a pairwise opposite manner. First placing grooves are provided on both sides of the placing table 2, and the two first placing grooves are arranged oppositely. Each first positioning member 5 is connected in each first placing groove. The first positioning member 5 is a second rotating cylinder. A first positioning plate 5.1 is connected to the piston rod of the second rotating cylinder. The two first positioning plates 5.1 are arranged oppositely. When placing the parts on the placing table 2, the two second rotating cylinders drive the two first positioning plates 5.1 to move towards the middle and rotate upward at the same time, enabling the two first positioning plates 5.1 to clamp and position the parts. When discharging, the two second rotating cylinders drive the two first positioning plates 5.1 to move outward and rotate downward at the same time, enabling the two first positioning plates 5.1 to release the parts, facilitating the employees to take down the parts.

[0022] The second positioning member 6 includes two second cylinders 6.1, such asFigure 2 As shown, two cavities are provided in the placement table 2. Two through holes are provided on one side wall of each cavity. Two of the second cylinders 6.1 are arranged in the cavities. The piston rods of the second cylinders pass through the corresponding through holes. A second positioning plate 6.2 is connected to the piston rods of the second cylinders 6.1. The second positioning plate 6.2 is driven to move by the second cylinders 6.1. The two rows of second positioning plates 6.2 move towards the middle to position the parts.

[0023] When clamping the parts, the two parts are respectively placed on the placement table 2. The parts are positioned and clamped by the first positioning member 5 and the second positioning member 6. Then, the first rotating cylinder 4.1 drives the two first pressing plates 4.3 to move downward while rotating, which can press the two parts simultaneously. In addition, while the first pressing plates 4.3 press the parts, the first cylinder 3.1 drives the rotating plate 3.2 to rotate, so that the rotating plate 3.2 drives the second pressing plate 3.3 to press the parts, thus completing the full-automatic clamping and fixing of the parts, which is convenient for subsequent processing.
