AI Technical Summary
Existing hydraulic cylinder assemblies with built-in displacement sensors are difficult to adjust the detection starting point quickly in CNC machine tools, and the sensors are easily affected by hydraulic oil and vibration environment, making the maintenance process complicated and resulting in low production efficiency.
A hydraulic cylinder assembly with a built-in displacement sensor was designed. The sensor detection starting point can be flexibly adjusted and quickly disassembled through adjusting and fixing components. A servo motor drives the threaded rod to move the slide plate. Combined with a fixing ring and a fixing chamber, the installation and disassembly process of the sensor is simplified.
It enables precise adjustment and rapid maintenance of the sensor detection starting point, improves the versatility of components and equipment maintenance efficiency, reduces equipment replacement and maintenance costs, and minimizes equipment downtime.
