Description
Technical Field
The invention relates to the technical field of automobile part machining, in particular to a welding slag prevention process for a bumper towing hook.
Background
The trailer hook is an important emergency rescue device on the automobile and is generally installed on a bumper of the automobile; when an automobile falls into a dilemma, a towing operation is often required to be carried out by towing a towing hook by means of other vehicles.
There are two mounting modes of the trailer hook and the bumper: a welded structure and a screwed structure; the welded structure refers to welding the towing hook directly to the bumper, and the screwed structure refers to welding the towing hook sleeve with internal threads to the bumper, and the towing hook is provided with external threads to be connected to the towing hook sleeve.
Fig. 10 shows a general bumper, which includes a bumper body frame 410 and a decorative cover 420, wherein the bumper body frame 410 and the decorative cover 420 are welded and fixed; in general, when the bumper frame 410 and the decorative cover 420 are welded, the bumper positioning jig is used to perform positioning operation and then welding operation.
When the welding operation of the parts of the bumper is performed, the welding operation of the towing hook or the towing hook sleeve is performed simultaneously; for the welding operation of the towing hook sleeve, the process requirement is relatively high: the circumferential weld at the contact position of the towing hook sleeve 430 and the bar body skeleton 410 does not allow a weld joint, and welding slag cannot be contained in the towing hook sleeve 430, which is required to improve the connection strength of the towing hook sleeve and the bar body skeleton and satisfy the convenience of the towing hook sleeve in later use.
At present, when the towing hook sleeve is welded with the bar body framework, a magnet type plug is generally placed in the towing hook sleeve to prevent welding slag from falling into the towing hook sleeve and ensure the continuous integrity of welding operation; if the magnet type plug falls off from the towing hook sleeve, the welding operation needs to be stopped immediately, and welding slag is prevented from entering the towing hook sleeve.
Because the magnet material of magnet formula end cap receives high temperature magnetism for a long time and can decay, the adsorption affinity weakens, and when bumper positioning fixture carries out whole upset operation, magnet formula end cap drops easily, causes the protection inefficacy, makes welding operation interrupt.
Therefore, how to solve the above technical problems is a technical problem that a person skilled in the art needs to solve.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.
