Description

Technical Field

[0001] The utility model relates to the field of servo drivers, in particular to a low-noise servo driver and a noise reduction structure thereof. Background Art

[0002] A servo drive, also known as a "servo controller" or "servo amplifier", is a controller used to control a servo motor. Its function is similar to that of a frequency converter on an ordinary AC motor. It is part of a servo system and is mainly used in high-precision positioning systems. It generally controls the servo motor in three ways: position, speed and torque to achieve high-precision transmission system positioning. It is a high-end product of transmission technology.

[0003] Now, silencer cotton is installed inside the servo drive to reduce the noise generated by the servo drive during operation. At the same time, a connecting rod is set, and a plurality of positioning cylinders are fixedly connected to the outer surface of the connecting rod. The heat sink is movably connected between the two positioning cylinders, and the heat sink is positioned on one side of the servo drive to dissipate heat. When the heat sink needs to be cleaned after long-term use, the nut on the first threaded rod is first turned out, and the positioning plate is pushed downward to make the positioning plate slide downward in the first positioning groove to move the positioning plate out of the slot. At this time, the heat sink can be rotated separately to clean the heat sink. After cleaning, the heat sink is rotated to one side of the servo drive, the positioning plate is pushed upward into the slot, and the nut is rotated to the first threaded rod to fix it. Then, the positioning plate is used to fix multiple heat sinks, so that the positioning is accurate, and there is no need to disassemble and install the heat sinks separately, which is easy to operate.

[0004] However, the heat sink cannot be removed for cleaning, so the heat sink can only be cleaned at the location where the servo drive is installed, which is inconvenient to clean the heat sink. At the same time, if the servo drive collides during transportation or handling, causing one or more heat sinks to be damaged, it is inconvenient to replace the heat sink.

[0005] Therefore, it is necessary to provide a low-noise servo drive and a noise reduction structure thereof to solve the above technical problems. Utility Model Content
