Passive trolley suitable for multiple models

Abstract

The invention discloses a passive trolley suitable for multiple vehicle types. The passive trolley suitable for the multiple vehicle types comprises a passive trolley platform which walks along a track and has a lock function, the passive trolley platform is provided with a fixed primary standard structure, a three-way stepless standard support mechanism and / or a two-way stepless standard support mechanism and / or a support stepless standard mechanism. The passive trolley can be simultaneously suitable for the multiple vehicle types, and by means of multiple adjustable stepless standard support mechanisms, multiple vehicle type stepless switching of the passive trolley is achieved. A walking power source of the passive trolley and a power source of a switching mechanism are independently arranged on the exterior of the passive trolley, the weight of the trolley is reduced, and the trolley is portable and simpler. According to the passive trolley suitable for the multiple vehicle types, a support pressing mechanism and a support part which make contact with a trolley body are connected with the passive trolley through insulating parts, and welding electric leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for automobile manufacturing, in particular to a passive trolley suitable for multiple vehicle models applied on an automobile welding line. Background technique [0002] The development trend of the world's automobiles is from mass production to multi-variety and small-batch production. In order to meet the extensive and diverse needs of automobile consumers and adapt to the fierce competition in the automobile market, major automobile manufacturers in the world continue to shorten the model change cycle. To speed up the update of vehicle types, the function of modern automobile welding lines is gradually becoming more flexible. [0003] The single-model automatic production line is a welding production line designed for one model. When there are large differences in multiple models, it cannot be operated on the same production line. The multi-model automatic hybrid production line is...

AI Technical Summary

Problems solved by technology

The trolleys on the existing automobile welding line are generally single-model active trolleys. This kind of trolley has a complex structure, heavy weight, high manufacturing costs and maintenance costs, and it is impossible to switch between multiple models.
