Description

Technical Field

[0001] This utility model relates to the field of five-axis turntable manufacturing technology, and more specifically, to an actively waterproof five-axis turntable. Background Technology

[0002] Traditional five-axis rotary tables have the following drawbacks: braking components (such as friction pads) typically rely on a single-layer rubber seal or labyrinth seal, but under high-speed rotation and frequent start-stop conditions, the sealing interface is prone to wear and micro-gaps. For example, external impurities can seep in, causing an electrolyte film to form between the moving and stationary friction pads, leading to brake slippage; long-term water accumulation accelerates the corrosion of braking components; traditional solutions rely on periodic manual disassembly and inspection, but water accumulation inside the braking components is often only discovered after functional failures (such as motor short circuits or a sudden drop in the coefficient of friction) occur. Statistics show that 60% of sudden rotary table failures are directly related to hidden water seepage, and existing liquid level sensors are mostly externally mounted on the housing surface, making it impossible to monitor the accumulation of liquid inside the braking zone in real time.
