Problems solved by technology
In the entire railway freight car manufacturing industry, the welding of the two elevation welds of the end wall and end beam of the C70A open car has always been completed by electric welding operators in the form of manual overhead welding. The requirements are very high, and the welding efficiency is low and the labor intensity is high
Therefore, the welding quality of this weld is extremely unstable and affects the appearance quality of the vehicle

Embodiment Construction
[0011] see figure 1 , The seam tracking device of the present invention adopts a mechanical tracking device, which is connected to the mounting bracket 21 through a rotating shaft 20 and can rotate around the rotating shaft 20 . When the angle adjustment plate 22 is slid upward, the initial angle between the mechanical tracking device and the horizontal plane increases; when the angle adjustment plate 22 is slid downward, the initial angle between the mechanical tracking device and the horizontal plane decreases. The initial height and initial extension distance of the tracking wheel 27 can be controlled by adjusting the size of the initial angle between the mechanical tracking device and the horizontal plane. Tracking cylinder 23 links to each other with tracking head carriage 24, can drive tracking head carriage 24 and the linear guide rail slide block 25 that is installed on it and tracking head 26 stretches out together when tracking cylinder 23 stretches out. Tracking he...

Abstract
The invention discloses a weld tracking device which comprises a mounting bracket, an angle adjustment plate, a tracking cylinder, a tracking head, a tracking wheel, a tracking-head carriage, a first spring and a second spring, wherein the first spring is arranged between the tracking head and the tracking-head carriage, and the second spring is arranged between the mounting bracket and the tracking cylinder; and the tracking cylinder is connected with the tracking head, the tracking head drives the tracking wheel, and the angle adjustment plate is connected with the tracking cylinder and the mounting bracket. The weld tracking device disclosed by the invention has the advantages that because of replacing artificial welding with automatic welding, the parameters of the angles of welding torches, the distances between the front ends and centers of welds, and the like can always keep correct, thereby ensuring the formation on overhead fillet welds is good.
Description
technical field [0001] The invention relates to a tracking device, in particular to a tracking device for elevation angle straight welding seams. Background technique [0002] For a long time, in the manufacturing technology of the C70A open car in the entire railway wagon manufacturing industry, the welding of the 2700mm-long elevation weld formed after the end wall and end beam are assembled has always been done by manual overhead welding. The specific method is as follows; firstly, the paired gondola car body is placed horizontally on the bench of the welding station, and then the welding operator uses CO2 gas shielded welding to carry out manual welding in the form of overhead welding. In order to ensure the good formation of the angled weld, the welding operator should first adjust the welding current and voltage according to the process requirements. Then make the welding torch form an angle of 40°-50° with the vertical plane where the welding seam is located, and alw...
