Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil storage cylinder manufacturing, and particularly relates to an oil storage cylinder bottom cover press-fitting and welding device. BACKGROUND

[0002] At present, in the production and manufacturing process of shock absorbers, the oil storage cylinder component needs to be used. The specific manufacturing process of the oil storage cylinder includes the following steps. First, the oil storage cylinder is positioned on the first tool. Then, the bottom cover is placed at the opening end of the oil storage cylinder. Then, the bottom cover is pressed into the inside of the oil storage cylinder by a pneumatic cylinder. Then, the oil storage cylinder with the pressed-in bottom cover is taken off from the tool and placed on the second tool. The seam welding machine moves to make the welding wheel disc contact the outside of the oil storage cylinder and apply a certain pressure to the outside of the oil storage cylinder. Then, the welding wheel disc rotates to drive the oil storage cylinder to rotate. In the process of rotating the oil storage cylinder, the welding wheel disc welds the side wall of the oil storage cylinder and the bottom cover to form a continuous weld. In the existing manufacturing process of the oil storage cylinder, multiple processing steps are needed, and the oil storage cylinder needs to be switched and transported between different manufacturing equipment, which is high in production cost and low in production efficiency.

[0003] For example, in the Chinese invention patent with the application number CN202411413266.9 and the application date October 11, 2024, a cylinder bottom cover press-fitting device is recorded. The device includes a press, a turnover seat, a support column, an annular support, a top rod, and a spring. The turnover seat is hingedly connected to the surface of the workbench of the press near the side of the operator's work station. The lower part of the support column is fixedly connected to the turnover seat. The upper part of the annular support is provided with a positioning sleeve matched with the inner diameter of the cylinder. The middle part of the top rod is provided with an outwardly extending support ring, and the lower part of the top rod is movably inserted into the inner hole of the upper end of the support column. The spring is located between the lower end of the top rod and the bottom of the inner hole of the support column. The upper end of the top rod is fixedly provided with a lower pressing head matched with the inner wall of the cylinder bottom cover. The lower pressing head and the upper pressing head of the press are coaxial in the vertical direction. The upper pressing head of the press presses the bottom cover placed on the lower pressing head into the cylinder provided with the support column and the positioning sleeve to complete the bottom cover press-fitting. In the comparative document, only the bottom cover press-fitting step for the cylinder can be implemented. If the bottom cover welding operation needs to be continued, the cylinder needs to be disassembled and transported to the welding equipment for welding, which causes high production cost and low production efficiency.
