One cover body is provided with a pipeline mounting hole which is a single-hole cover body, and the other cover body is provided with two pipeline mounting holes which are double-hole cover bodies. In the production process, two ends of the shell need to be welded with two cover bodies manually. At present, the shell and the cover of the silencing drum are welded on a rotatable working table, and technicians can weld the shell and the cover while rotating to realize annular welding of the shell and the cover. The specific operation process is that a cover body is firstly placed on a workbench, a shell is placed at one end of the cover body, and then spot welding in four directions is carried out at the joint of the cover body and the shell, so that the cover body and the shell are fixed. Then the upper part and the lower part of the shell are reversed, another cover body is placed at the other end of the shell, and the four-direction spot welding is carried out at the joint of the two. And finally, the rotary worktable performs full-line welding on the connecting seam of the cover body and the shell.
To summarize, the welding quality of the cover and the housing must be guaranteed, and the cover and the housing must be accurately positioned in addition to the welding technician. At present, only one rotatable workbench with a plane surface is not provided with a positioning function for the shell and the cover body. At present, the welding positioning of the cover body and the shell is carried out manually, the positioning mode is easy to cause errors, and the welding quality is difficult to ensure. At present, no welding positioning tool for the shell of the silencing drum exists in the market. Therefore, the auxiliary welding tool for the shell of the automobile sound attenuation drum is specially designed by the company so as to realize the positioning of the cover body and the shell body, and the welding quality is ensured.
