AI Technical Summary

Technical Problem

Existing flute-shaped tube welding fixtures cannot achieve the rotation of the flute-shaped tube, which affects welding efficiency, and the spattering of welding slag endangers the safety of operators.

Method used

A welding fixture for flute-shaped tubes was designed, comprising a support base plate, a rotating mechanism, an absorption and filtration mechanism, and a fixing mechanism. The support base plate is provided with an air intake hole and a filter box. The rotating mechanism enables the flute-shaped tubes to rotate 360°. The absorption and filtration mechanism absorbs welding slag and gas during welding. The fixing mechanism securely clamps two sets of flute-shaped tubes.

Benefits of technology

It improves the efficiency and precision of flute tube welding, ensures the safety of the processing environment and the health of workers, and effectively filters welding slag and gas, avoiding the harm to workers caused by welding slag splashing.

Abstract

This utility model discloses a welding fixture for flute-shaped tubes, specifically a support base plate. A C-shaped support frame is fixedly mounted on the upper end of the support base plate. Suction holes are symmetrically arranged on the inner sidewall of the support frame near the top. An absorption and filtration mechanism is fixedly connected to the lower rear side of the suction holes via a pipe. The absorption and filtration mechanism includes a filter box connected to the suction holes via a pipe. This utility model, through its rotating mechanism, allows the fixed flute-shaped tubes to rotate 360°, greatly improving welding efficiency. Simultaneously, the absorption and filtration mechanism effectively filters the gases and slag generated during welding, ensuring a good working environment and worker safety. Furthermore, the fixing mechanism can clamp and fix two sets of flute-shaped tubes at once, improving both the precision and efficiency of flute-shaped tube processing.
