Method for using welding jig of scrambling motorcycle frame back fork

Abstract

The invention discloses a method for using a welding jig of a scrambling motorcycle frame back fork, and belongs to the technical field of welding application. The method includes the steps that first, the position of a lifting lug positioning support in the welding jig of the scrambling motorcycle frame back fork is adjusted; second, all parts of the frame back fork correspond to supports on the upper end face of a tool base plate for positioning; third, fast chucks I are pushed so that back fork shaft positioning pins at the tops of the fast chucks I can be clamped into inner holes of a back fork shaft; fourth, fast chucks II are pushed so that back wheel fixing sheets can abut against back fork positioning supports, and back fork positioning pins penetrate through fixing grooves in the back wheel fixing sheets and then are clamped into back fork positioning holes of the back fork positioning supports; fifth, the position of the lifting lug positioning support is adjusted, so that shock-absorbing seat lifting lugs and shock-absorbing seat positioning spacer bushes are clamped; and sixth, the frame back fork is fixed completely, and welding is conducted. According to the technical scheme, the frame back fork is accurate in positioning in the welding process, the dimensional precision of the frame back fork after welding is guaranteed, and welding efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of welding applications, and more specifically, to a method of using a welding fixture for the rear fork of a cross-country motorcycle frame. Background technique [0002] During the processing of the existing welded frame rear forks, workers mainly rely on experience to fix the processed parts by spot welding and then add welding. This welding method requires high skills and experience of the workers, low work efficiency, and welding. The quality cannot be guaranteed. Therefore, it is necessary to design a special welding fixture for welding between the components of the rear fork of the frame, so as to improve the welding efficiency and ensure the dimensional accuracy after welding, which is of great significance. [0003] After searching, the Chinese patent number is: 2014106000132, the application date is: October 31, 2014, and the name of the invention is: a welding fixture for a movable seat frame. The applic...
