It is widely known that reducing downtime for tool changes is crucial for increasing productivity and maximizing production capacity. Therefore, precise positioning and repeatable accuracy in the clamping process during machining are key to enhancing efficiency and quality.

In high-precision workpiece processing, conventional mandrels are difficult to meet process requirements due to their tendency to produce significant jumps. Currently, in the support of fixture technology, liquid expansion fixtures are one of the best choices for solving high-precision operations such as thin-walled processing, gear hobbing/insert hobbing, and the like.

The Liquid Expansion Clamp is a tool for automatic positioning, clamping, and support of product workpieces. Unlike conventional hydraulic clamps, the Liquid Expansion Clamp utilizes static pressure expansion technology. After applying pressure to the clamp, the hydraulic medium generates tremendous pressure under the action of the pressure mechanism, forcing the deforming element to uniformly deform elastically in all 360° circumferences of the clamping range, achieving tightness on the workpiece's locating holes.

The liquid clamp has the following major advantages in use:

Ensure precision in processing

Hydraulic clamping fixtures are utilized for installation and positioning, enabling rapid and precise determination of the mutual positions between workpieces, machine tools, and cutting tools, as well as the positional accuracy of the workpiece. This process is unaffected by the worker's skill level, ensuring machining precision and continuous stability.

(2) Enhance production, reduce costs

Using liquid expansion clamps to fixture workpieces allows for quick positioning and clamping, significantly reducing the time for loading and unloading. Fixing workpieces with liquid expansion clamps enhances their rigidity, enabling increased cutting allowances. This, combined with multi-piece, multi-station fixtures and effective clamping mechanisms, all contribute to improved labor productivity and safety. The stable product quality and reduced scrap rate effectively lower production costs.

(3) Machining of various size specifications of workpieces

Utilizing attachments like diameter springs and spline springs, a variety of size specifications for workpieces can be processed, no longer restricted to traditional single workpiece manufacturing. This effectively enhances production efficiency and reduces loading and unloading time.

(4) Expand the process range of machine tools

Utilizing liquid expansion clamps can alter the purpose of the original machine tool and expand its application range, achieving multi-functional capabilities with a single machine, effectively reducing production costs.

(5) Reduce the labor intensity for workers

The use of liquid pressure clamping fixtures for workpiece holding is convenient, safe, quick, and can alleviate the labor intensity for workers.

The liquid涨clamp finds nearly universal application across various scenarios, including gear processing for hobbing, grinding, rolling, shaving, and gear inspection, as well as for holding thin-walled parts in lathe and outer diameter grinding operations.
