Description

Automobile chassis conveying device for electric automobile assembly production Technical Field The invention belongs to the technical field of manufacturing of new energy automobiles, and particularly relates to an automobile chassis conveying device for electric automobile assembly production. Background In order to meet the conveying requirements of the electric automobile chassis under the scenes of heavy load, high-pressure precision, multi-station precise connection and the like, the positioning precision, the running stability and the battery safety in the chassis conveying process are ensured, and meanwhile, the high-efficiency circulation beat of the fixed path of the assembly workshop is adapted, so that RGV (rail guided vehicle) is adopted for conveying. RGVs are composed primarily of a carriage, a conveyor track, and a conveyor mechanism. After the conveying mechanism is started, the bearing frame can move along the conveying track, and then the chassis is driven to move. However, during the conveyance, the chassis sometimes collides with other objects, for example, a rear-end collision phenomenon occurs. To cope with such a situation, a protective structure such as a bumper strip is usually mounted on the carrier. However, the prior art has the problems that on one hand, when the collision occurs, the conveying mechanism can not automatically stop conveying, the bearing frame still continuously moves, the collision degree is further increased, and the protection effect of the anti-collision strip is poor. On the other hand, the crashproof strip is generally installed on the loading ledges through bolt fastening or welded mode, lacks the buffering design, and this not only damages the crashproof strip easily, and later replacement crashproof strip still can increase staff's work load, and frequent replacement crashproof strip also can increase the cost simultaneously. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide an automobile chassis conveying device for electric automobile assembly production, so that the technical problems that when an impact occurs, a conveying mechanism cannot automatically stop conveying, the impact degree is further aggravated, the protection effect of a crashproof strip is poor, the crashproof strip is fixedly arranged on a bearing frame, the buffer design is lacked, the crashproof strip is damaged, the workload of workers is increased when the crashproof strip is replaced at the later stage, and the cost is also increased when the crashproof strip is replaced frequently are solved. In order to achieve the aim of the invention, the technical scheme adopted by the invention comprises an automobile chassis conveying device for electric automobile assembly production, comprising: The conveying rail is horizontally arranged; the bearing frame is arranged on the conveying track and can slide along the conveying track; The conveying mechanism is arranged between the conveying track and the bearing frame, and the bearing frame can move along the conveying track by starting the conveying mechanism; the anti-collision component is movably connected to the bearing frame and is positioned at the front end of the bearing frame in the moving direction; The first elastic piece is arranged between the anti-collision member and the bearing frame and is used for buffering after the anti-collision member is stressed; and the braking component is arranged between the anti-collision component and the conveying mechanism, generates displacement after the anti-collision component is stressed, and drives the braking component to operate so as to brake the conveying mechanism. Compared with the prior art, the invention has the advantages that: (1) According to the automobile chassis conveying device for the electric automobile assembly production, when an obstacle exists in front of the bearing frame or collision risks exist between the bearing frame and other objects in the moving process of the bearing frame, the anti-collision member can firstly contact the obstacle and bear collision force. The chassis on the bearing frame is effectively prevented from being directly impacted by collision, and the possibility of the chassis being damaged by collision is reduced. Meanwhile, the movable connection mode enables the anti-collision member to generate certain motion relative to the bearing frame when receiving collision force, conditions are provided for subsequent buffering and braking actions, and the protection effect is further enhanced. (2) According to the automobile chassis conveying device for electric automobile assembly production, when the anti-collision component moves towards the bearing frame due to collision force, the first elastic piece is compressed. By utilizing the elastic deformation of the first elastic piece, the first elastic piece can absorb and disperse collision energy, reduce the impact of collision force on the bearing f
