Butt-joint installation positioning device for electrical wheel automobile engine and main motor and using method thereof

Abstract

The invention relates to the technical field of mechanical equipment assembly, in particular to a butt-joint installation positioning device for an electrical wheel automobile engine and a main motor and a using method thereof. The butt-joint installation positioning device consists of a strip plate of which the center is provided with a threaded hole and both ends are respectively and symmetrically provided with circular holes, two positioning pin shafts which have the same size and are respectively connected with the circular holes of the strip plate, a bolt connected with the threaded holeof the strip plate, an oscillating bar which is slidably connected with the bolt and an adjusting shaft arranged on the oscillating bar. During use, the positioning pin shafts are inserted into an installation hole on an outer ring of the main motor, and an oscillating needle is rotated to determine the position of a pin hole on an inner ring of the main motor; the positioning pin shafts are inserted into an installation hole on an outer ring of the engine, and an inner ring of the engine is rotated according to the position of the adjusting shaft on the oscillating needle to determine the position of the pin shafts on the inner ring of the engine; and the butt-joint installation is performed. The butt-joint installation positioning device has the advantages of simple structure, good adjusting effect and time and labor saving, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment assembly, in particular to a docking installation positioning device and a use method of an electric wheel vehicle engine and a main motor. Background technique [0002] When the electric wheel vehicle engine and the main motor are connected and installed, if the attached image 3 As shown, the outer ring 6 and the inner ring 7 of the engine of the electric wheel vehicle are fixedly connected with the outer ring 10 and the inner ring 11 of the main motor respectively through the bolt I8 and the bolt II9, and are arranged on the inner ring of the engine of the electric wheel vehicle before the fixed connection. The pin shaft 12 and the pin hole 13 that is located on the main motor must be aligned and connected. The connection of the outer ring is relatively easy, but the connection of the inner ring is difficult due to structural limitations and the lack of special positioning and alig...

AI Technical Summary

Problems solved by technology

The connection of the outer ring is relatively easy, but the connection of the inner ring is difficult due to structural limitations and no special positioning and alignment tools. The maintenance personnel can only adjust the relative positions of the positioning pins and holes of the two assembly parts intuitively To be accurate, once a deviation occurs during assembly, it is difficult to correct, and the equipment has to be readjusted on the ground

Each installation of this equipment requires the cooperation of the crane and the workers. In this case, the labor intensity of the workers is high, and at least 4 people are required to cooperate for about 1 hour, or even longer, and the crane is also added. The occupied time reduces the safety factor, making other operations that require the assistance of cranes in the operation area unable to proceed normally, resulting in a decrease in overall work efficiency and a corresponding increase in labor costs and equipment use costs
