[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0018] like Figure 1As shown, a pneumatic gripper for component testing includes a fixed base 1 and an adjusting assembly 3. Hydraulic rods 2 are mounted on both sides of the fixed base 1. The hydraulic rods 2 control the movement of movable blocks 301 on both sides and clamping plates of different shapes to clamp and limit the components. The adjusting assembly 3, used for quick replacement of the clamping blocks, is located at the output end of the hydraulic rods 2. The adjusting assembly 3 includes movable blocks 301, a rotating rod 302, a mounting rod 303, an arc-shaped clamping plate 304, and a straight clamping plate 305. The rotating rod 302 is mounted in the center of the movable block 301 and is driven and controlled by a motor. The mounting rod 303 and the clamping plate are rotated to adjust their positions. The lower end of the rotating rod 302 is connected to the mounting rod 303. The rotating rod 302 and the mounting rod 303 are fixedly connected. The arc-shaped clamping plate 304 and the straight clamping plate 305 are symmetrically distributed about the center point of the mounting rod 303. The arc-shaped clamping plate 304 is installed on the left and right sides of the mounting rod 303. The arc-shaped clamping plate 304 and the straight clamping plate 305 adjust the corresponding clamping plates according to the clamping surface of the parts as the mounting rod 303 rotates. The replacement speed is fast, the operation is simple, and the clamping effect can be guaranteed. The straight clamping plate 305 is installed on the front and rear sides of the mounting rod 303.

[0019] like Figure 2 As shown, a connecting rod 4 is installed on the upper end of the fixed base 1, and a rotating plate 5 is installed inside the connecting rod 4 via a rotating shaft. The rotating plate 5 is driven by the control component 9 to adjust the angle of the adjustment component 3, etc., inside the mounting frame 6. The mounting frame 6 is installed on the outer side of the rotating plate 5. The fixing plate 7 and fixing hole 8 on the top of the mounting frame 6 assemble and connect the gripper and the tooling under the fixing of bolts. Fixing plates 7 are installed on both sides of the mounting frame 6. The mounting frame 6 and the fixing plate 7 are fixedly connected, and the surface of the fixing plate 7 is provided with fixing holes 8.

[0020] like Figure 3 As shown, the lower surface of the mounting bracket 6 is equipped with an auxiliary angle adjustment control component 9, and the mounting bracket 6 is U-shaped. The control component 9 includes a hydraulic rod 901 and a fixed inclined block 902. The fixed end of the hydraulic rod 901 is equipped with the fixed inclined block 902. The hydraulic rod 901 pushes the rotating plate 5 to adjust the angle by telescopic movement. The control component 9 also includes an adapter plate 903 and a connecting frame 904. The output end of the hydraulic rod 901 is equipped with the adapter plate 903. The adapter plate 903 enables the hydraulic rod 901 to rotate and adjust accordingly with the rotating plate 5 during telescopic adjustment, ensuring the normal angle adjustment of the rotating plate 5. The side of the adapter plate 903 is equipped with a connecting frame 904 through a rotating rod.

[0021] In summary, the pneumatic gripper of this component testing fixture is first based on... Figures 1-3The structure shown in the diagram involves assembling the mounting bracket 6 and the tooling by placing their mounting surfaces in contact. Bolts are then used to connect the grippers and tooling through the fixing plate 7 and fixing holes 8. When clamping parts, the hydraulic rod 2 extends, causing the moving blocks 301 and the arc-shaped clamping plate 304 or straight clamping plate 305 on both sides to move away from each other. When the parts are positioned inside the clamping plates, the hydraulic rod 2 retracts, clamping and fixing the parts. When the outer surface of the parts has different shapes (arc or flat), the control rotating rod 302, driven by a motor, controls the mounting rod 303 and the clamping plates to rotate and adjust their positions. The arc-shaped clamping plate 304 and the straight clamping plate 305 adjust their corresponding clamping plates according to the clamping surface of the parts as the mounting rod 303 rotates. This allows for fast replacement, simple operation, and ensures effective clamping. When angle adjustment is required, the hydraulic rod 901 extends and retracts to push the rotating plate 5 for angle adjustment. The adapter plate 903 allows the hydraulic rod 901 to rotate and adjust accordingly with the rotating plate 5 during extension and retraction. At this time, the rotating plate 5 drives the adjustment components 3, etc., to adjust the angle.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
