Abstract

The invention discloses a welding tool for increasing the qualification rate of chain wheel welding and a welding technology using the same. Based on the characteristics of welding deformation and thereverse deformation principle, two end faces are machined into a certain taper in the reverse direction of deformation during chain piece finish turning, the end faces are restored after welding deformation, end face runout is controlled, and the qualification rate of the welding technology is increased. Besides, the welding tool is redesigned; an anti-splashing plate and a locking pressing plateare used for pressing 90% of the two end faces of a chain piece completely with only 10% exposed, a sufficient welding space is reserved, and a hub is pressed by the end faces; then, automatic girthwelding is performed; and the welding tool is detached after cooling, and welding is completed. Thus, the welding process is stable, the end face runout and variation of the chain piece can be effectively controlled, and the qualification rate of the welding technology is increased.

Description

technical field [0001] The invention relates to the production and processing field of sprockets, in particular to a welding tool for improving the welding pass rate of sprockets and a welding process using the same. Background technique [0002] A sprocket is a wheel with cog-type sprockets designed to engage precisely pitched blocks on a chain link or cable. Sprockets are widely used in chemical, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries for mechanical transmission. In daily production, the qualified rate of one-time delivery of sprocket products cannot meet the production requirements. After analysis, it is found that the main reason is the unqualified welding process and the unqualified fine boring process, among which the unqualified welding process is the most important reason. [0003] In view of the reasons for the low qualification rate ...
