A car engine assembly line and its circulation device

Abstract

The invention discloses an assembly line used for an automobile engine and a transferring device thereof. The transferring device comprises a rail which extends in parallel to the assembly line of the automobile engine, the start end and the tail end of the rail are provided with lifting and dropping mechanisms respectively, the rail comprises an upper rail and a lower rail, preset vertical distance is obtained between the upper rail and the lower rail, a to-be-transferred engine is installed on a support of a trolley, walking wheels of the trolley are supported on the rail and switched between the upper rail and the lower rail under the action of the two lifting and dropping mechanisms; accordingly, by means of a supporting form of the trolley, supporting and transferring of engines with a plurality of types are achieved, smooth switching of the plurality of types of the engines in transferring is convenient, the universality of the transferring device is improved, the improvement cost of equipment is lowered, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile assembly, in particular to a circulation device used in an automobile engine assembly line. The invention also relates to an assembly line comprising the above-mentioned circulation device. Background technique [0002] In the modern automobile manufacturing industry, every automobile is born by the assembly of several units. In the automobile assembly process, a pre-installation line is usually set up for the engine and some related parts, which is used to complete the installation of the engine suspension, gearbox, compressor and some wiring harness pipes before being installed on the body. In the assembly process, in order to realize the fixing of the engine and ensure the space required for the installation process, a circulation device is usually used to realize the transfer of related parts. [0003] Such as figure 1 As shown, most of the existing circulation devices are in the form of...

Problems solved by technology

[0004] However, the tray-type circulation device is a rigid structure, and the positioning pins and support rods on it are fixedly connected to the tray, so that its positioning and supporting positions cannot be adjusted; and for engines of different sizes and specifications, the position of the supporting point and the positioning position cannot be adjusted. There are differences. The push plate circulation device is not universal. The circulation device of each specification can only correspond to the corresponding type of engine. When matching with other types of engines, the pallet circulation device needs to be modified, which is difficult to operate and costly; At the same time, operating errors are prone to occur during the refitting process, resulting in improper support of the engine and affecting the stability of the support
