A universal engine assembly trolley

Abstract

The invention relates to a universal engine assembly trolley. The universal engine assembly trolley comprises a trolley frame, a quadrangular stand column, an oil receiving tray, universal wheels and braking wheels, wherein the oil receiving tray is arranged in the trolley frame. A connecting shaft component comprises a connecting shaft and a flange connected at the front end of the connecting shaft, the rear end of the connecting shaft is matched with a shaft hole formed at the upper end of the front side face of the quadrangular stand column and extends into the quadrangular stand column to be in matched connection with a worm wheel, a hand wheel component comprises a hand wheel and a worm, one end of the worm is in matched connection with the hand wheel, the worm inserted into the upper end of the left side face of the quadrangular stand column is meshed with the worm wheel, a mounting plate is fixedly connected with the flange, the upper portion of the mounting plate is provided with two flat and straight limiting slots in bilateral symmetry, two mounting sliding plates in bilateral symmetry are arranged on the lower portion of the mounting plate and are respectively provided with an oblique limiting slot, and the two oblique limiting slots are in bilateral symmetry. The universal engine assembly trolley is simple in structure and capable of meeting assembly requirements of engines of various vehicle models, and assembly efficiency can be improved.

Description

technical field [0001] The invention relates to an engine assembly tool, in particular to a universal engine assembly trolley. Background technique [0002] At present, engine assembly is divided into design stage and production stage assembly, and different tooling needs to be designed and designed. [0003] In addition, the engine itself is a combination of precision and high-speed components, which has high requirements for assembly quality. With the deepening of engine research and development, each engine company needs to assemble a large number of engine prototypes in the initial stage of research and development and mass production. In the original assembly process, there is no special assembly device for the engine prototype, and the existing assembly technology cannot adapt to the assembly of multiple models, because the positions of the four transmission mounting holes on the engine block of each model are different. The center line of the four transmission mount...

AI Technical Summary

Problems solved by technology

[0004] (1) The structure is complex and the strength is not enough; the rotating disc is connected with one end of the output shaft, one end of the four universal adjustment rods is respectively connected with the rotating disc, and the four transmission mounting holes on the engine block are connected through four connecting screws. The column is connected to four universal adjustment rods, which not only has insufficient strength, but also affects the operation; in addition, the positioning of the engine cylinder is through the limit rod of the limit device on the pillar of the car body and the limit on the rotating disk. Hole fit to achieve, the structure is more complex;

[0005] (2) The operation is cumbersome and the reliability is poor; the distribution of the four transmission mounting holes on the engine block of different models is different. To replace an engine block, it is necessary to adjust the directions of the four universal adjustment rods; For the engine cylinder block, you need to take out the limit rod, and then insert the limit rod to limit

Not only cumbersome to operate, but also poor reliability

[0006] Due to the existence of the above deficiencies, it has affected the promotion and use of
