Abstract

The invention relates to a welding and positioning device for a flywheel assembly in the technical field of motorcar part manufacture, comprising air cylinder connecting pieces, a limit piece, a clamp base, an inner gripping sleeve, an outer gripping sleeve and a positioning ring, wherein the inner gripping sleeve and the outer gripping sleeve are respectively arranged on the upper brim of the positioning ring, the limit piece is sheathed on the inner brim of the clamp base, and a plurality of the air cylinder connecting pieces respectively run through the outer gripping sleeve, the positioning ring and the clamp base in order; and the upper and the lower ends of the air cylinder connecting pieces are respectively fixedly connected with the limit piece and a welding air cylinder, and the outer brim of the inner gripping sleeve is matched with the inner brim of the outer gripping sleeve. Aiming at solving the disadvantages of the prior art, the device changes the mode of clamping positioning to greatly eliminate the thermal distortion of a gear ring and effectively reduce the outside diameter jumpiness height and the end face jumpiness height of the flywheel assembly which needs to be welded, thus compared with the prior art, the welding efficiency is increased by 11 percent.

Description

technical field [0001] The invention relates to a device in the technical field of auto parts manufacturing, in particular to a welding positioning device for a flywheel assembly. Background technique [0002] Generally, the flywheel welding fixture adopts the method of compressing the ring gear and the flywheel disc, and processes it with the method of plane positioning. This is a mature processing method for welding flywheel assemblies that has been used for many years. However, due to the large amount of heat generated by welding, thermal deformation of the ring gear occurs during welding, which seriously affects the runout of the outer diameter of the ring gear. In order to improve the welding quality, it is necessary to eliminate the thermal deformation of the ring gear during welding. [0003] After searching the literature of the prior art, it is found that the Chinese patent application number 200420061514.X and the authorized announcement number CN2726789Y record a...
