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...

Problems solved by technology

Since the water inlet pipe 100 and the water inlet pipe bracket 200 are special-shaped parts, and during production and processing, the angle between the left end pipe 110, the right end pipe 150 and the branch pipe 120 on the water inlet pipe 100 is determined, so the water inlet pipe 100 and the water inlet pipe bracket 200 During welding, the alignment accuracy between the arc-shaped welding part 210 and the right end pipe 150 is particularly important. Once there is a slight deviation, the left end pipe 110, right end pipe 150 and branch pipe 120 in the water inlet pipe 100 cannot be installed accurately at the same time. , the produced part will be scrapped

At present, when the factory is welding the water inlet pipe 100 and the water inlet pipe bracket 200, manual welding is generally used. When welding, it is first necessary to draw a line on the right end pipe 150 of the water inlet pipe 100 to mark the welding position, and then at the same time need to draw a line on the arc of the water inlet pipe bracket 200. The marking on the welding part 210 requires at least two workers during welding, one of them will accurately align and fix the marking on the right end pipe 150 and the marking on the arc welding part 210, and the other will weld. The method mainly has the following defects: 1) the alignment steps between the right end pipe 150 of the water inlet pipe 100 and the arc-shaped welding part 210 of the water inlet pipe bracket 200 are cumbersome, time-consuming and laborious, and the situation of inaccurate alignment is prone to occur; The water pipe 100 is a curved round pipe with a certain angle, which is prone to deflection and rolling during welding. The welding quality cannot be guaranteed, the error rate is high, and the welding efficiency is low. It has become increasingly difficult to meet the requirements of modern high-speed and high-quality production; 3) The water inlet pipe bracket 200 is a special-shaped piece, and the position is easy to be fixed during welding, and position deviation is prone to occur, resulting in unqualified products
