Welding tool for rear installation supporting base of truck body

Abstract

The invention relates to the technical field of automobile manufacturing, in particular to a welding tool for a rear installation supporting base of a truck body. The welding tool for the rear installation supporting base of the truck body comprises the base, a first air cylinder, a compressing arm, a connection board, a locating base, a second air cylinder, a rotary shaft and a locating pin, wherein the first air cylinder is fixed to the connection board; one end of the compressing arm is in rotary connection with the telescopic end of the first air cylinder; the other end of the compressing arm is fixedly connected with the locating base; the compressing arm is further in rotary connection with the connection board; the second air cylinder is fixed to the base; the telescopic end of the second air cylinder is in rotary connection with the connection board; the connection board is connected with the base through the rotary shaft; the locating pin is located on the connection board. As certain compressing force is exerted on the rear installation supporting base of the single-row truck body, the welding deformation of the rear installation supporting base of the single-row truck body is reduced, the assembly of an assembly shop is improved, and meanwhile through simple and rapid switching, accurate locating and space receding are carried out on third-section longitudinal beams of row-and-a-half truck bodies and double-row truck bodies, and welding is convenient.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a welding tool for mounting a supporting seat behind a truck body. Background technique [0002] Truck bodies are generally divided into single-row, semi-row and double-row bodies according to their length. The rear installation support seat is the connection part between the vehicle body and the vehicle frame, and the rear installation support seat of the single-row body is close to the third section of the longitudinal beam of the row and a half row and the double row body. In the prior art, when welding, the single-row rear mounting support seat only has simple positioning without applying a pressing force, while the third section of the longitudinal beam of the half-row and double-row body is positioned by the side, the positioning is not accurate, and the operation The space is narrow, the welding is difficult, and the operation is inconvenient.
