AI Technical Summary

Technical Problem

Existing flange cutting fixtures can only clamp one flange at a time, resulting in low processing efficiency.

Method used

A tooling was designed that includes a fixed base, a clamping cylinder, an L-shaped sliding clamping block, a limiting slider, and a fixed clamping block. The clamping cylinder drives the L-shaped sliding clamping block to cooperate with the fixed clamping block, which can clamp multiple flanges at the same time. The clamping height can be adjusted by the limiting protrusion and the adjusting slider to accommodate flanges of different sizes.

Benefits of technology

It enables the simultaneous clamping of multiple flanges, improving processing efficiency, adapting to flanges of different specifications and sizes, and reducing frequent clamping operations.

Abstract

This utility model discloses a flange cutting fixture, including a fixed base and a flange. The fixed base has symmetrically formed limiting grooves. A clamping cylinder is fixedly connected to the fixed base, and an L-shaped sliding clamping block is fixedly connected to the output end of the clamping cylinder. Limiting sliders are symmetrically fixed below the L-shaped sliding clamping blocks, and the limiting sliders slide in cooperation with the limiting grooves. A fixing block is fixedly connected to the fixed base, and a placement step is formed on the fixing block. The placement step cooperates with the L-shaped sliding clamping block. An adjusting groove is formed behind the placement step, and an adjusting slider is slidably installed within the adjusting groove. A limiting protrusion is connected to the front of the adjusting slider. By activating the clamping cylinder, the L-shaped sliding clamping block moves backward, and the L-shaped sliding clamping block, in cooperation with the fixing block, clamps and fixes the flange inside the placement step, enabling the simultaneous clamping and fixing of multiple flanges.
