Curved pipe press-fitting welding auxiliary device and curved pipe press-fitting welding method

Abstract

The invention relates to a curved pipe press-fitting welding auxiliary device. The curved pipe press-fitting welding auxiliary device comprises a curved pipe auxiliary fixing device installing plate,a left curved pipe auxiliary fixing device, a right curved pipe auxiliary fixing device and a swing rod installing seat, wherein the left curved pipe auxiliary fixing device and the right curved pipeauxiliary fixing device are symmetrically installed on the left side and the right side of the curved pipe auxiliary fixing device installing plate, and the swing rod installing seat is installed at the middle section of the upper portion of the front side face of the curved pipe auxiliary fixing device installing plate. The invention further discloses a method for conducting press-fitting weldingof curved pipes through the curved pipe press-fitting welding auxiliary device. The curved pipe press-fitting welding auxiliary device and the curved pipe press-fitting welding auxiliary method havethe beneficial effects that the output force of the curved pipe press-fitting welding auxiliary device is large, maintenance is simple, the performance cost ratio is high, and the curved pipe press-fitting welding auxiliary device is suitable for short-distance press-fitting work with a short press-fitting force stroke, replaces workers to conduct the work of press-fitting of two curved pipes located on the same circle, is high in efficiency, good in installation parallelism, and high in assembling accuracy.

Description

technical field [0001] The invention relates to an arc-shaped tube press-fit welding auxiliary device and an arc-shaped tube press-fit welding method, belonging to the technical field of mechanical semi-automation. Background technique [0002] Press-fitting refers to the assembly process of pressing two parts with an interference fit into a mating position. In the actual production process, not only two straight pipes need to be pressed together, but sometimes two curved pipes on the same circle need to be pressed together, and the distance from the central axis of the two curved curved pipes to the same circle is equal , there is a lack of a semi-automatic equipment that presses two elbows on the same circle together, so the previous production process is done manually by workers, but the mass production line is done manually by workers. Assembly problems are prone to occur, and the production process has relatively high assembly technical requirements for workers. Once t...

Problems solved by technology

[0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is: to provide an arc-shaped tube press-fit welding auxiliary device and an arc-shaped tube press-fit welding method to solve the lack of a two-way joint that will be on the same circle It is a semi-automatic equipment that presses and fits two bent pipes together, so the previous production process is done manually by workers, but the mass production line is done manually by workers, which is prone to assembly problems, and the production process has a great influence on the assembly of workers. The technical requirements are also relatively high. Once there is worker turnover and replacement, it will affect the production efficiency and cause the problem of product quality decline.
