Description

Technical Field

[0001] The utility model relates to the technical field of fixing devices, in particular to a servo driver fixing device with a buffering function. Background Art

[0002] A servo drive, also known as a servo controller or servo amplifier, is an electronic controller used to control servo motors. Its primary function is to receive control signals and convert them into rotational control for the motor, thereby achieving precise positioning and speed control. The servo drive, connected to the motor, can accelerate, decelerate, stop, or reverse rotation. This controller is primarily used in industrial automation systems that require high-precision and high-speed control. The servo drive's mounting mechanism is a crucial component in ensuring stable and safe operation. In mechanical equipment, vibration can reduce the servo drive's control accuracy, affecting the motor's response speed and positioning accuracy. Long-term vibration can accelerate wear of the servo drive's internal components, shortening its service life.

[0003] Among many existing technologies, Chinese patent application CN218473585U discloses a fixing mechanism based on a servo drive, including a pair of parallel support bars, each end of which is provided with a U-shaped groove opening outward, and a plurality of screw holes are provided between the two U-shaped grooves. The screws pass through the screw holes and are connected to the servo drive housing, and are connected to the external support surface after passing through the U-shaped groove by a locking screw.

[0004] However, this patent application first connects the support bar to the servo drive housing with screws, then vertically positions the entire structure close to the support surface, and secures the support bar to the support surface with locking screws. This does not provide any buffering, and long-term vibrations can damage the servo drive. Furthermore, the system uses multiple locking screws for fixing, making disassembly and assembly cumbersome during maintenance.

[0005] Based on this, the utility model designs a servo driver fixing device with a buffering function to solve the above problems. Utility Model Content
