Abstract

The invention discloses welding and shape-correcting tooling equipment for vehicle frames of passenger vehicles and a use method of the welding and shape-correcting tooling equipment. The welding and shape-correcting tooling equipment comprises a base platform, locating pin units, workpiece clamping units, shape-correcting units, lifting units, a vehicle frame subjected to shape-correcting, an oil cylinder, a fixing plate, connection rods, pressing blocks, a clamping arm, positioning blocks and a stop block, and is characterized in that the locating pin units, the workpiece clamping units, the shape-correcting units, the lifting units and the vehicle frame subjected to shape-correcting are arranged on the base platform; the welding and shape-correcting tooling equipment has the characteristics of being simple in structure, low in cost, convenient for operation and good in correcting effect; the oil cylinder is utilized to output strong power, and a four-bar linkage locking principle is utilized, so that good compressing, locking and shape-correcting effects on the vehicle frame are ensured; the whole shape-correcting process can be finished automatically by machinery; the efficiency is high; the safety is high; the qualification rate of the vehicle frames subjected to shape-correcting can be above 90%; and the yield is greatly improved.

Description

technical field [0001] The invention relates to the field of passenger car welding process equipment, in particular to a passenger car frame welding calibration tooling equipment and a method for using the same. Background technique [0002] The frame of a passenger car is the main structure that bears the body, and is also the main part that resists the impact force during a collision, so it is an important part related to the quality and safety of the body of a passenger car. In order to ensure the strength of the frame, plates with a thickness of more than 4mm are generally used, and the high-strength welding method of argon arc welding is used to weld them into a frame structure to ensure the firmness and stability of the frame. However, due to the use of thick plates and argon arc welding process, the frame during welding is subject to high heat and concentrated stress, resulting in large deformation of the frame after welding, and poor quality stability of the welded f...
