Abstract
This utility model relates to a welding fixture for assembling the rear axle seat and hydraulic pipe of an excavator boom, including a main board, a support plate, a hydraulic pipe positioning block, and a rear axle seat positioning plate. The hydraulic pipe positioning block is located on the top of the main board and is used to fix the installation position of the hydraulic pipe and the rear axle seat. The rear axle seat positioning plate is set perpendicular to the main board and fits against the side plate of the rear axle seat. Through the main board, support plate, hydraulic pipe positioning block, and rear axle seat positioning plate, the welding positioning of the rear axle seat and hydraulic pipe is realized, and the welding process of the rear axle seat and hydraulic pipe is moved forward, solving the problems of difficult welding inside the boom, inability to guarantee welding quality, and high operation difficulty, thus improving welding efficiency and accuracy. The hydraulic pipe positioning block ensures accurate spatial alignment of the hydraulic pipe and the rear axle seat, avoiding welding deviation and preventing welding offset.
