The Gear Hobbing Liquid胀Clamping Fixture (actuated by a push rod) is a high-precision fixture specifically designed for gear hobbing operations. Below is a detailed description of the fixture:

Structural Features

The gear hobbing胀clamp（actuated by a push rod）is primarily composed of the clamp body, push rod, expansion sleeve, sealing assembly, drive unit, and positioning elements.

• Clamping Assembly BodyThe base structure of the fixture, used for installing and supporting other components, and ensuring the precise positioning of the workpiece.

• Trolley rodThrough the action of the drive mechanism, the push rod moves within the fixture body, thereby pushing the expanding sleeve to expand or contract.

• Expansion sleeveThe胀套 is a critical component of the fixture, closely fitting the outer surface of the workpiece and securing it through expansion. The material and structural design of the胀套 must meet high precision and rigidity requirements.

• Sealed ComponentsTo ensure the hydraulic cavity within the fixture is sealed properly, preventing hydraulic oil leakage and ensuring the normal operation of the fixture.

• Drive unitPower the rod movement, usually utilizing hydraulic or pneumatic drive methods. The design of the drive unit must consider the clamping force of the fixture and its response speed.

• Positioning componentsUsed to ensure accurate positioning of workpieces in fixtures, enhancing processing precision. The accuracy and stability of the locating elements are crucial for the performance of the fixture.
