High-Precision Hydraulic Fixtures 高精密液压夹具

Overview 产品概述

Patented Hydraulic-Expansion Technology — Leading in China 专利液胀技术——国内领先

Really Reliable's hydraulic expansion fixtures are designed specifically for gear honing and gear grinding applications. At the core is a patented liquid-expansion mechanism that delivers precise, damage-free clamping of hardened gear blanks while enabling rapid workpiece changeover — critical for high-volume automotive gear production.

瑞利来液压夹具专为珩齿和磨齿应用设计。核心是一套专利液胀机构，可对淬硬齿坯实现精确、无损伤的夹持，同时实现工件快速更换——这对汽车齿轮大批量生产至关重要。

Multiple patents have been granted across the fixture design, covering the liquid-expansion sleeve, modular mounting interface, and quick-change mechanism. The technology is domestically leading and can be readily extended to new application areas beyond gear machining.

多项专利覆盖夹具设计的液胀涨套、模块化安装接口和快换机构等方面。该技术国内领先，且可轻松扩展至齿轮加工以外的新应用领域。

Core Features 核心特性

• 1
  High-efficiency fixture — high strength, precision, long service life 高效夹具——高强度、高精度、高寿命
  The hydraulic expansion design evenly distributes clamping force, eliminating point contact stress concentrations that cause premature wear in conventional clamping systems. 液胀设计均匀分布夹紧力，消除传统夹持系统因点接触应力集中导致的过早磨损。
• 2
  Unique liquid-expansion interchangeable sleeve 独特液胀式可换涨套
  The interchangeable sleeve concept allows the same base fixture body to be adapted for different workpiece bores with a quick sleeve swap — reducing tooling inventory and changeover time. 可换涨套设计允许同一夹具本体通过快速更换涨套适应不同工件孔径——降低工装库存，缩短换型时间。
• 3
  Large expansion range → automatic clamping, no workpiece damage 大膨胀量 → 自动装夹，无夹伤
  The large hydraulic expansion range accommodates workpiece bore tolerances and enables self-centering automatic clamping without any risk of surface damage to finished gear bores. 大液胀量可适应工件孔径公差，实现自定心自动装夹，不会对已加工齿轮孔面造成任何表面损伤。
• 4
  Modular quick-change design — one-touch quick-mount 模块化快换设计——一键快装
  The modular interface enables tool changes in seconds rather than minutes, making the fixture suitable for mixed-model production lines and short-run batch schedules. 模块化接口使工装更换时间从分钟级缩短至秒级，使夹具适合混线生产和小批量生产计划。
• 5
  Multiple patents — leading in China; expandable to new applications 多项专利——国内领先；可扩展至新应用领域
  Patented across five design areas. The core hydraulic expansion platform can be adapted to non-gear applications including turning, boring, and broaching fixtures for similar workpiece configurations. 五项设计领域获得专利授权。核心液胀平台可适用于车削、镗削和拉削等非齿轮应用的类似工件夹持场景。
