A snap-off assembly that separates accessories from workpieces

Abstract

The invention discloses a breaking assembly for separating auxiliary materials from workpieces, comprising: a breaking mounting plate; a push driver installed on the breaking mounting plate; a rod-shaped fixing finger connected to the breaking mounting plate affixed and hang downward from the broken mounting plate; and a rod-shaped sliding finger, which is connected to the power output end of the push drive and hangs downward from the push drive; the fixed finger The bottom of the bottom is open to form a break-off accommodation chamber; the sliding finger is set opposite to the fixed finger, and the side of the sliding finger opposite to the fixed finger is fixedly connected with a break-through threading rod; the sliding finger is on the top Driven by the push driver, the fixing finger is moved closer to or farther away from, so that the break-off threading rod is inserted into the break-off accommodation chamber or withdrawn from the break-off accommodation chamber. According to the present invention, it is possible to prevent problems such as falling off of welding spots, cracking of welding seams, and deformation of workpieces due to excessive bending force applied to the folding lugs.

Description

technical field [0001] The invention relates to the field of welding, in particular to a break assembly for separating auxiliary materials from workpieces. Background technique [0002] In the field of welding, it is well known to use different structural forms of snap-off components to separate the auxiliary material from the workpiece after the workpiece has been welded. In the process of researching and realizing the separation of auxiliary materials and workpieces, the inventors found that there are at least the following problems in the broken components in the prior art: [0003] Most of the existing breaking components adopt a clamping structure, that is, after clamping the folding ears on the auxiliary material, the auxiliary material is bent up and down to realize the separation of the auxiliary material and the workpiece. With this structure, the workpiece is not cooled or cooled after welding. Incomplete, it is very easy to cause problems such as solder joint dro...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the main purpose of the present invention is to provide a snap-off assembly that separates the auxiliary material from the workpiece, which allows the ear to be snapped off by putting the ear on the snap-off rod. During the process, the folding lug weakens or disappears the transverse shear force generated during the breaking process by sliding back and forth along the broken sleeve rod, thereby preventing the solder joints from falling off and soldering due to excessive bending force applied to the folding lug. Seam cracking, workpiece deformation and other problems, improving the welding yield and reducing production costs
