AI Technical Summary

Technical Problem

In the copper bar welding process, the existing technology aligns the copper bar by squeezing it against the inner wall of the positioning groove. This requires the welder to use a vise for a long time, which can easily lead to misalignment of the welding position and reduce the welding accuracy.

Method used

A copper bar welding positioning fixture was designed, comprising a side clamping assembly and a top pressing assembly. It utilizes a forward and reverse motor to drive a threaded rod and a bevel gear mechanism to achieve automatic clamping and pressing of the copper bar, avoiding continuous manual clamping and improving welding accuracy and stability.

Benefits of technology

The automatic clamping and pressing mechanism ensures accurate copper bar welding position, avoids misalignment, improves welding precision and stability, and reduces the inconvenience of manual operation.

Abstract

This utility model discloses a copper bar welding positioning fixture, comprising: a base, a positioning groove on the upper surface of the base, a side clamping assembly on the base, a top pressing assembly on the side clamping assembly, the side clamping assembly including a forward and reverse motor, the forward and reverse motor being fixedly mounted on the side wall of the base, a first threaded rod being fixedly mounted on the output shaft of the forward and reverse motor, a second threaded sleeve being threadedly mounted on the outer wall of the first threaded rod, a second connecting rod being fixedly mounted on the outer wall of the second threaded sleeve, a side clamping plate being fixedly mounted on the top end of the second connecting rod, a first stroke being formed on the upper surface of the base, and the second connecting rod being slidably connected to the inner wall of the first stroke. Through the above structure, two copper bars are effectively clamped tightly, preventing misalignment and improving welding accuracy.
