The Helical Gear Cutting Tool Holder (Manual Drive) is a high-precision tool holding device specifically designed for helical gear cutting. Below is a detailed description of the device:
Structural Features
Gear hobbing fluid-actuated tool holder (manual drive) mainly consists of the tool holder body, fluid-actuated shaft, manual drive mechanism, sealing components, and connecting parts.
Razor blade shaftThe main shank of the tool holder needs to have sufficient rigidity and precision as the fundamental structure for the tool holding device, to ensure stability and accuracy during the machining process.
Liquid-filled shaftThe liquid-filled shaft is the core component of the tool holder, securing the tool through static pressure expansion technology. It can undergo elastic deformation under the action of a manual drive mechanism, thereby fitting tightly onto the handle or specific area of the tool.
Manual drive mechanismThe manual drive mechanism provides the power for the expansion or contraction of the liquid-impregnated mandrel. It typically includes a manual pump or handle, which the operator can rotate or pull to drive the movement of the liquid-impregnated mandrel.
Sealed ComponentsSealed components are used to ensure proper sealing of the hydraulic cavity within the tool bar, preventing hydraulic oil leakage. They typically consist of components such as seals and gaskets, and require regular inspection and maintenance.
Connective componentsConnective parts are used to link the tool spindle with other components of the gear cutting machine (such as the main shaft, tool holder, etc.). They must possess adequate strength and precision to ensure the stability and accuracy of the tool spindle during the machining process.
