Description

Technical Field

[0001] This utility model relates to the field of encoder installation technology, and specifically to an encoder mounting bracket. Background Technology

[0002] In motor systems, encoders are crucial position and speed feedback devices used to monitor the angle, speed, and direction of the motor rotor in real time. They convert mechanical motion into electrical signals using photoelectric, magnetic, or inductive principles, providing precise feedback to the closed-loop control system and ensuring efficient and stable motor operation. Encoders are typically mounted on the motor shaft end or side, rigidly connected to the motor via couplings or flange structures to guarantee measurement accuracy. High-resolution encoders can detect minute angular changes and are suitable for high-precision applications such as servo control, robot joints, and CNC machine tools. Furthermore, encoders enhance the motor's dynamic response, suppress vibration and errors, and improve system reliability. Protective designs (such as IP67) make them adaptable to dust, oil, and electromagnetic interference in industrial environments, making them an indispensable core component of modern automation equipment.

[0003] In existing technologies, encoder mounting brackets have complex structures, typically assembled from multiple parts (such as bases, adjusting blocks, shims, and elongated mounting plates). The installation process requires sequentially fixing multiple components, involving numerous steps, consuming significant time and effort, and incurring high costs. To achieve the required coaxiality and perpendicularity, installers must use precision measuring tools such as dial indicators and feeler gauges for repeated manual adjustments. This process is highly dependent on the operator's experience and skill level, resulting in inconsistent measurement accuracy. Different operators, or even the same operator operating under different conditions, may achieve significantly different installation accuracy. After disassembling and replacing the encoder or performing maintenance and reinstallation, readjustment is almost always necessary, making it difficult to guarantee that the installation position is completely consistent with the pre-disassembly position, thus affecting the reliability and consistency of the equipment. Summary of the Invention

This invention includes a fixing frame, a mounting plate, and a concentric mount as an auxiliary mounting component. The device has a simple structural design, facilitating installation. By improving the structural design of the fixing frame and applying the concentric mount during installation, the coaxiality and perpendicularity of the motor and encoder meet the technical specifications. Even after disassembling and replacing the encoder or performing maintenance and reinstallation, the original coaxiality and perpendicularity can be maintained, thereby improving the stability and consistency of the device and enhancing measurement accuracy.
