Description

Technical Field

[0001] The utility model relates to the technical field of fault detection devices, and more specifically to a servo drive fault detection device. Background Art

[0002] A fault detection device is a device that monitors, diagnoses and analyzes the operating conditions of equipment or systems, promptly detects possible faults, and takes appropriate measures to repair or adjust them. A servo drive is a controller used to control a servo motor. It is mainly used in high-precision positioning systems. Generally, a fault detection device is needed to detect faults after the servo drive is produced.

[0003] For example, a servo drive fault detection device proposed in the announcement number CN220019765U includes a T-shaped table, a guide groove, a photoelectric switch, a side clamp, a screw hole slide, a lead screw, a push-in plate, a terminal plug detection head, a data cable, a detection display screen, a loading plate, a cylinder, an L-shaped plate and a motor. The beneficial effect is that the utility model has a reasonable design, and multiple terminal plug detection heads matching the terminal interface on the servo drive are installed on the push-in plate in the same distribution position, and the position operation is consistent. The push-in plate and the terminal plug detection head thereon can be pushed by the cylinder to be inserted into the corresponding terminal interface on the servo drive, solving the problem of cumbersome plug-in detection operation one by one and improving the efficiency of fault detection.

[0004] The above solution has the following defects during use:

[0005] The positions of multiple terminal plug-in detection heads on the push-in plate remain fixed, and the servo drives are of different sizes and models, and the positions of the terminal interfaces on the corresponding servo drives are also different, making it difficult for the terminal plug-in detection heads to accurately adapt to the terminal interfaces of servo drives of different sizes and models. They can only be used for a certain model of servo drive, with a small scope of application and low practicality. Therefore, it is urgent to improve the technology of the fault detection device to improve this equipment.

[0006] To this end, the utility model proposes a servo drive fault detection device. Utility Model Content

Then, under the push of the push-pull cylinder 4, the detection terminal 5 and the double-slot connecting wire board 7 are driven to move toward the servo driver, so that multiple terminal docking detection heads 9 are close to the terminal interface of the servo driver until they are plugged together. If the terminal docking detection head 9 does not match the terminal interface position of the servo driver, the plug-in board 1101 in the flexible clamping mechanism 11 is pulled to move away, so that it drives the plug rod 1102 to move outward and separate from the slot 1104 in the initial position. , and drive the elastic double-sided drum block 1105 to separate from the double-concave slot 1106 at the initial position, cancel the fixation between the movable sleeve 10 and the pair of guide plates 8, and then move the movable sleeve 10 and the terminal docking detection head 9 along the double-slot connecting wire plate 7 and the pair of guide plates 8 to move horizontally, and make corresponding position adjustments according to the terminal interface position of the servo drive, so that the terminal docking detection head 9 matches the terminal interface position of the servo drive.
