Passive trolley platform suitable for multiple models

Abstract

The invention discloses a passive trolley platform suitable for multiple vehicle types. The passive trolley platform is used for carrying a supporting component which is used for fixing a vehicle type workpiece to be machined. The passive trolley platform comprises a platform base plane, first angle iron used for locating and fixing the passive trolley platform is arranged at the bottom of the platform, first through holes are formed in the first angle iron, and the axis of each first through hole is perpendicular to the walking direction of a passive trolley. The quantity of the first angle iron is two, and the two pieces of first angle iron are arranged on the left side and the right side of the passive trolley respectively. A locking device is arranged on a rail where the passive trolley walks. The locking device comprises a controller, a cylinder and a first touch switch, wherein the cylinder and the first touch switch are connected with the controller. The passive trolley platform is light and simple in structure; a walking power source and a power source of a switching mechanism of the passive trolley are both independently arranged outside the passive trolley, so that the weight of the trolley is reduced, and the trolley is lighter and simpler.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for automobile manufacturing, in particular to a passive trolley platform applicable to 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 producti...

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.
