Abstract

The invention discloses a car subframe installing and welding fixture and relates to the technical field of car subframes. The installing and welding fixture comprises a support, a front body moving positioning block, a rear body moving positioning block, a left moving pressing positioning block, a right moving pressing positioning block, an intermediate fixed positioning block, an upper positioning block and a hydraulic system. The installing and welding fixture can guarantee positioning accuracy of workpieces under coaction of the hydraulic system, multiple positioning blocks and positioning pins, is capable of clamping four workpieces at the same time and can weld the workpieces one by one, thus, production efficiency is greatly improved, and labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of the auxiliary frame of a car. Background technique [0002] As an important part of a car, the sub-frame must be accurate in size and shape when producing the sub-frame. Usually, the clamps for welding the subframe are single, and generally adopt nuts and bolts for pre-tightening and positioning. Such a structure not only has low work efficiency, but also cannot ensure that the shape error of the workpiece is within the allowable range during welding. The patent document with the application number 201020572206.9 discloses a welding mold for sub-frame assembly of a dump truck, and discloses the structure in detail: six legs are symmetrically welded on the bottom of the bottom plate, and two longitudinal beam positioning grooves are symmetrically welded on the top of the bottom plate The steel is used for the lateral positioning of the left and right longitudinal beams of the subframe. The longitudinal be...
