A combined welding positioning and clamping device for automobile special water inlet pipe workpiece and bracket

Abstract

The invention provides a special car water inlet pipe workpiece and support combined welding positioning clamping device. The special car water inlet pipe workpiece and support combined welding positioning clamping device comprises a base plate, a welding positioning base installed at the middle portion of the base plate, a right pipe end positioning base installed on the right side of the weldingpositioning base, a left pipe end positioning base installed on the left side of the welding positioning base, a pipe end compression device installed on the left side of the left pipe end positioning base, a branch pipe limiting device installed on the front side of the left pipe end positioning base, a support positioning plate installed on the right side of the branch pipe limiting device, a first quick clamp installed on the side of the support positioning plate and a second quick clamp installed on the back side of the welding positioning base. By means of the special car water inlet pipe workpiece and support combined welding positioning clamping device, quick positioning and clamping of a water inlet pipe and a water inlet pipe support can be achieved, the poor welding quality caused by movement of the water inlet pipe or the water inlet pipe support in the welding process is reduced, and the welding efficiency and quality are improved.

Description

technical field

[0001] The invention relates to the technical field of auto parts processing, in particular to a combined welding positioning and clamping device for a special water inlet pipe workpiece and a bracket for an automobile. Background technique

[0002] Most of the automotive components are precision components, and the machining accuracy requirements are extremely strict. The automotive water inlet pipe is a kind of pipeline that acts on the cooling of the automotive engine. As an important part of the engine, it plays a vital role in the cooling of the engine. Its machining accuracy and installation accuracy have strict requirements, and its shape is as figure 1 As shown, the automobile engine water inlet pipe 100 is composed of a left end pipe 110, a branch pipe connecting pipe 130, an arc bend pipe 140, a right end pipe 150 and a branch pipe 120, wherein the branch pipe connecting pipe 130 is welded on the right end of the left end pipe 110, and the branch pi...
