[0020] In the present invention, when an AC servo driver is used to precisely control a servo motor, the AC power line is connected to the wiring terminals of the driver. The driver converts the AC power into the required voltage and frequency and outputs it to the servo motor to control the motor and achieve precise adjustment of position, speed and torque. However, this operation may cause the following problems: after multiple connecting wires such as the input power line and the output power line are connected to the wiring terminals on the driver, the connecting wires and the wiring terminals are exposed and lack a protective structure. If a worker touches them by mistake, a dangerous situation may occur. Impurities such as dust in the air may adhere to and corrode the wiring terminals, reducing their service life. By setting an adjustment structure When you need to wire the driver, you need to turn and open the protective cover first to prevent it from hindering the operation. Pull the limit rod in the direction away from the support frame. During this process, the limit rod moves along the support frame and gradually slides out of the limit hole. The spring is in a stretched state. Wait for the limit rod to completely slide out of the limit hole, release the limit on the protective cover, turn and open the protective cover, and after the protective cover is rotated to a certain angle, release the limit rod. The limit rod moves toward the direction close to the support frame under the action of the spring force until the limit rod slides into the limit hole at the corresponding position to fix the position of the protective cover. Then you can perform the wiring operation. After the wiring operation is completed, turn the adjusting rod, and the adjusting rod moves away from the protective cover with the help of the thread. The protective cover moves in the direction of the protective cover, and the adjusting rod drives the positioning plate to slide out of the positioning slot on the movable clamping plate to release the limit on the movable clamping plate, and then the movable clamping plate is moved along the support frame in the direction away from the adjusting rod, so that the movable clamping plate slides away from the area of the wiring terminal. Similarly, the limiting rod is operated to release the limit on the protective cover, and the protective cover is rotated to close. In this process, since the movable clamping plate is moved away, it will not be blocked by the connecting wire. The protective cover continues to be rotated until it is closed. At this time, the protective cover is located on the upper surface of several connecting wires. Similarly, the limiting rod is operated to limit the protective cover to fix the rotation angle of the protective cover, and the movable clamping plate is moved along the support frame close to the adjusting rod. In this process, the movable clamping plate is located on the connecting wire. The adjusting rod is rotated in the opposite direction, and the adjusting rod moves toward the direction close to the protective cover with the help of the thread. In this process, the adjusting rod drives the positioning plate to slide into the positioning groove, and the adjusting rod uses the positioning plate to limit the moving splint, and drives the moving splint to move toward the direction close to the protective cover, until the moving splint and the protective cover cooperate to squeeze and limit the connecting wire, thereby realizing the use of the protective cover that can be easily opened and closed to shield and protect the wiring terminals on the driver, and the use of the moving splint in conjunction with the protective cover to clamp and limit multiple connecting wires after wiring is completed, so that the contact effect between the connecting wire and the wiring terminal is more stable.

[0033] Detailed explanation of usage: When using an AC servo driver to precisely control a servo motor, the AC power line is connected to the driver's terminal 4. The driver converts the AC power into the required voltage and frequency and outputs it to the servo motor to control the motor and achieve precise adjustment of position, speed, and torque. However, this operation will cause the following problems. After multiple connecting wires such as the input power line and the output power line are connected to the terminal 4 on the driver, the connecting wires and the terminal 4 are exposed and lack a protective structure. If a worker touches them by mistake, a dangerous situation may occur. Dust and other impurities in the air may adhere to and corrode the terminal 4, reducing its service life. By setting an adjustment structure 6, when the driver needs to be wired, the protective cover 6 needs to be turned open first. 02 to prevent it from hindering the operation, pull the limit rod 603 in the direction away from the support frame 601. During this process, the limit rod 603 moves along the support frame 601 and gradually slides out of the limit hole 605, and the spring 604 is in a stretched state. When the limit rod 603 completely slides out of the limit hole 605, the limit on the protective cover 602 is released, and the protective cover 602 is rotated to open. After the protective cover 602 is rotated to a certain angle, the limit rod 603 is released. Under the action of the elastic force of the spring 604, the limit rod 603 moves towards the direction close to the support frame 601 until the limit rod 603 slides into the limit hole 605 at the corresponding position to fix the position of the protective cover 602. Then the wiring operation can be carried out. After the wiring operation is completed, the adjusting rod 614 is rotated. The adjusting rod 614 is adjusted by The auxiliary thread moves in the direction away from the protective cover 602, and the adjusting rod 614 drives the positioning plate 615 to slide out of the positioning groove 616 on the movable clamping plate 610, releasing the limit on the movable clamping plate 610, and then the movable clamping plate 610 is moved along the support frame 609 in the direction away from the adjusting rod 614, so that the movable clamping plate 610 slides away from the area of the terminal 4, and the limiting rod 603 is operated in the same way to release the limit on the protective cover 602, and the protective cover 602 is rotated and closed. In this process, since the movable clamping plate 610 is moved away, it will not be blocked by the connecting wire, and the protective cover 602 is continued to be rotated until it is closed. At this time, the protective cover 602 is located on the upper surface of several connecting wires. Similarly, the limiting rod 603 is operated to limit the protective cover 602 so that the protective cover 602 is rotated at an angle of 1. The movable splint 610 is fixed, and is moved along the support frame 609 to be close to the adjusting rod 614. During this process, the movable splint 610 is located below the connecting line until the adjusting rod 614 slides into one end of the movable splint 610, and the positioning plate 615 is opposite to the positioning groove 616. The adjusting rod 614 is rotated in the opposite direction, and the adjusting rod 614 moves toward the direction close to the protective cover 602 with the help of the thread. During this process, the adjusting rod 614 drives the positioning plate 615 to slide into the positioning groove 616. The adjusting rod 614 uses the positioning plate 615 to limit the movable splint 610, and drives the movable splint 610 to move toward the direction close to the protective cover 602, until the movable splint 610 cooperates with the protective cover 602 to squeeze and limit the connecting line. When the protective cover 602 rotates,The coil spring 606 always gives a torsional force to the protective cover 602, so that the protective cover 602 is more stable when rotating. The protective cover 602 is driven to rotate by operating the handle 607, which is convenient for the user to rotate the protective cover 602. The auxiliary groove 611 improves the limiting effect of the movable clamping plate 610 and the protective cover 602 on the connecting line. The pulley 612 reduces the friction between the movable clamping plate 610 and the inner wall of the support frame 609, so that the movable clamping plate 610 moves along the support frame 609 more smoothly. The movable clamping plate 610 is further limited, so that the movable clamping plate 610 is more stable when moving along the support frame 609. The friction of the operating end of the adjustment rod 614 is increased by the anti-slip pad 617, which is convenient for the user to rotate the adjustment rod 614, and the connection terminal 4 on the driver is shielded and protected by the protective cover 602 that can be easily opened and closed. The movable clamping plate 610 is used in conjunction with the protective cover 602 to clamp and limit the multiple connection wires after the wiring is completed, so that the contact effect between the connection wire and the connection terminal 4 is more stable.
