Roller can lug base earring assembly spot welding group to fixture

Abstract

The invention belongs to the technical field of mining machinery manufacturing equipment, and relates to a pairing jig for a spot welding assembly of a roller jar ear base earring assembly. The three hydraulic cylinders on the positioning pin assembly in the sleeve, the rear positioning pin assembly of the sleeve and the front positioning pin assembly of the sleeve accurately position the rear single ring of the clevis and the front single ring of the clevis. Clamps, right side plate oblique pressure quick clamps, left side plate oblique quick clamps and rear side plate rear hook quick clamps use the dead point of the plane four-bar mechanism or guide rod mechanism to press and position each side plate, and turn the disc Make a half turn to weld the inside weld. Compared with the human-powered hydraulic pressure, the present invention can ensure the precise positioning of the single ring behind the earring and the single ring in front of the earring, and can remove the mold conveniently; using tooling to determine the relative size of each workpiece is more accurate than determining the size by marking the marking line, and the produced The size of the parts can be more uniform; reduce the labor force and improve work efficiency; use the working principle of the dead point of the quick clamp clamp, which is easy to use, can increase the pressing force, and improve work efficiency.

Description

technical field [0001] The invention belongs to the technical field of mining machinery manufacturing equipment, and relates to manufacturing equipment for roller can ears, in particular to a pairing jig for a spot welding group of earring components of a roller can ear base. Background technique [0002] The Roller Can Ear Base Earring Assembly includes the Earring Right Panel, Earring Back Side Panel, Earring Front Side Panel, Earring Back Single, Earring Front Single, and Earring Left Panel. Among them, the axis line of the inner hole of the rear single ring of the earring and the axis line of the inner hole of the front single ring of the earring are located on the same straight line, and the same straightness tolerance requirements are relatively high. The axis line of the rear single ring of the earring or the front single ring of the earring The axial center line of the earring is set in the front and back horizontal direction, and there is a certain distance between ...

AI Technical Summary

Problems solved by technology

Manual spot welding groups often have to draw marking lines on each workpiece, and rely on the drawn lines to position each other. This will inevitably lead to large errors in the processing process. The outer dimensions of the welded earring components are different from those expected. big difference

Another important point is that after the full welding is completed, due to the existence of welding deformation, it is very difficult to extract the pin shaft from the rear single ring of the earring, the spacer sleeve and the single front ring of the earring. Using tools such as hammers will cause The workpiece produces new deformations
