Abstract

The invention discloses a processing method and an auxiliary device of a combined assembly of a curved-beam motorcycle frame front part. The auxiliary device comprises a baseboard, a head tube assembly positioning mechanism arranged on the baseboard, a front suspension positioning mechanism of an engine and a main suspension assembly positioning mechanism of the engine. The positioning point of the front suspension positioning mechanism of the engine is an engine mounting hole on the engine front suspension; and the positioning point of the main suspension assembly positioning mechanism are a rear fork sleeve end hole and engine mounting hole of the main suspension of the engine. The method includes processing components individually, then positioning the components, welding the components by the auxiliary device, and finally welding other components of a frame. The auxiliary device has the advantages of simple structure, low cost, positioning reliability and convenience in operation; with two engine mounting holes and the rear fork sleeve as positioning reference, accuracy of engine mounting can be guaranteed by the processing method, and effects of mounting quality of the bending-beam motorcycle frame engine are achieved.

Description
