[0002] Electric grippers, commonly used in industrial automation, are widely applied in numerous industries such as automotive manufacturing, electronic assembly, and medical device production. Driven by electricity, they open and close, precisely gripping and transporting workpieces, significantly improving production efficiency and product quality.

[0003] As disclosed in the prior art document CN202420159048.6, the adjustable anti-loosening electric gripper, although it improves the gripping stability to a certain extent by limiting the upper and lower positions of the gripped part through the pressure block and the top block, still has room for improvement in the gripping effect for some objects with complex shapes and irregular curved surfaces. During the gripping process, objects such as disc-shaped objects are prone to deflect to one side or even loosen, which not only affects production efficiency but may also lead to damage to the object or cause safety accidents.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting an elastic component between the mounting plate and the pressure plate, utilizes the elastic force of the spring to allow the pressure plate to flexibly adapt to the surface of objects with complex shapes and irregular curves, preventing objects such as discs from deflecting to one side or loosening during the clamping process; at the same time, multiple evenly distributed pressure plates can apply clamping force from multiple points, further enhancing clamping reliability and reducing the risk of decreased production efficiency, object damage, and safety accidents caused by object loosening.

[0014] 2.

[0021] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0022] Please see Figure 1 , Figure 2 As shown, the adjustable anti-loosening electric gripper of this utility model includes a slide plate 1. There are two slide plates 1. The upper end of the two slide plates 1 is provided with a drive assembly. The drive assembly includes a fixed plate 13. The fixed plate 13 is slidably disposed with the slide plate 1. A bidirectional threaded rod 15 is rotatably installed in the middle of the fixed plate 13. The two ends of the bidirectional threaded rod 15 are respectively threadedly connected to the corresponding slide plate 1. Guide rods 14 are provided on both sides of the bidirectional threaded rod 15. The guide rods 14 are installed on the fixed plate 13 and are slidably disposed with the slide plate 1.

[0023] In this embodiment, the two slide plates 1 are slidably connected to the fixed plate 13 via the guide rod 14. The guide rod 14 restricts the slide plate 1 from rotating with the bidirectional threaded rod 15 and only allows axial translation. Therefore, the rotation of the bidirectional threaded rod 15 is converted into relative motion of the two slide plates 1. One end of the bidirectional threaded rod 15 is provided with a drive source 16. For the drive source 16, such as the servo motor commonly found in the market, the specific structure and working principle are not described in detail or limited here. The output shaft is connected to one end of the bidirectional threaded rod 15. When the drive source 16 is started, it drives the bidirectional threaded rod 15 to rotate around its own axis.

[0024] See Figure 1 , Figure 3As shown, the drive source 16 is mounted on the fixed plate 13. Mounting plates 2 are provided on both slide plates 1. Multiple mounting plates 2 are provided and evenly distributed on the slide plates 1. Mounting plates 2 are provided with mounting grooves 3 and mounting holes 4. Mounting plates 2 are inserted into mounting grooves 3 and fixedly connected to mounting holes 4 by fixing bolts. A pressure plate 10 is provided on the side of the two slide plates 1 that is close to each other. A rubber pad 17 is provided on the pressure plate 10.

[0025] Combination Figure 3 , Figure 4 As shown, multiple pressure plates 10 are provided, and each pressure plate 10 is provided with an elastic component between it and the mounting plate 2. The elastic component includes a threaded cylinder 5. The mounting plate 2 at the corresponding position of the threaded cylinder 5 is provided with a threaded groove 6. The threaded cylinders 5 are threadedly connected to each other. A slide rod 7 is slidably provided on the threaded cylinder 5. The slide rod 7 and the threaded cylinder 5 are clearance fit to ensure smooth sliding. One end of the slide rod 7 passes through the mounting plate 2 and is connected to the pressure plate 10. The elastic component also includes a spring 8, which is sleeved on the slide rod 7 and is located inside the threaded cylinder 5.

[0026] In this embodiment, a threaded cap 9 is provided at the end of the threaded cylinder 5 away from the mounting plate 2. The threaded cap 9 is threadedly connected to the threaded cylinder 5. One end of the spring 8 rests on the threaded cap 9, and the other end of the spring 8 is installed on the protruding structure of the slide rod 7. When the slide rod 7 moves, it will compress the spring 8 sleeved on its outside. After the spring 8 is compressed, it generates an elastic restoring force. This force is transmitted to the pressure plate 10 through the slide rod 7, so that the pressure plate 10 continuously applies pressure to the workpiece. This achieves clamping and avoids workpiece damage caused by rigid contact through the elastic buffer of the spring 8. A sleeve 11 is provided at one end of the slide rod 7. The sleeve 11 is threadedly connected to the slide rod 7, and the sleeve 11 is hinged to the pressure plate 10 through the limiting shaft 12.

[0027] The implementation principle is as follows: Before clamping the workpiece, the threaded cylinder 5 can be rotated to rotate within the threaded groove 6 on the mounting plate 2, thereby adjusting the overall extension length of the elastic component to adapt to different clamping requirements.

[0028] When it is necessary to clamp the workpiece, the drive source 16 is started, which drives the bidirectional threaded rod 15 to rotate on the fixed plate 13. Since the two ends of the bidirectional threaded rod 15 are respectively threadedly connected to the corresponding slide plate 1, and under the guidance of the guide rod 14, the two slide plates 1 will move closer to each other. As the slide plate 1 moves, the mounting plate 2 installed on the slide plate 1 and the pressure plate 10 connected to the mounting plate 2 through the elastic component also move and gradually approach the workpiece.

[0029] When the pressure plate 10 comes into contact with the workpiece, the workpiece will generate a reaction force on the pressure plate 10, causing the slide rod 7 to slide inside the threaded cylinder 5. During the sliding process, the slide rod 7 will compress the spring 8 sleeved on it. One end of the spring 8 presses against the threaded cap 9, and the other end acts on the slide rod 7, thereby generating an elastic force. This elastic force is transmitted to the pressure plate 10 through the slide rod 7, so that the pressure plate 10 can fit tightly against the surface of the workpiece.

[0030] For workpieces with complex shapes and irregular curved surfaces, since the sleeve 11 at one end of the slide bar (7) is hinged to the pressure plate 10 through the limiting shaft 12, the pressure plate 10 can rotate at a certain angle according to the shape of the workpiece surface, ensuring that multiple pressure plates 10 can make good contact with the workpiece surface. At the same time, the elastic effect of the spring 8 can continuously apply pressure, effectively preventing objects such as discs from deflecting to one side or loosening during the clamping process.

[0031] When it is necessary to release the workpiece, the drive source 16 rotates in reverse, causing the bidirectional threaded rod 15 to rotate in the opposite direction, so that the two slide plates 1 move away from each other, the pressure plate 10 disengages from the workpiece, the spring 8 returns to its original state, and the slide rod 7 returns to its initial position, waiting for the next clamping operation.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
