Three-dimensional circulating type frame riveting production line and operation method thereof

Abstract

The invention discloses a three-dimensional circulating type frame riveting production line and an operation method thereof, and belongs to the technical field of frame assembly.The three-dimensional circulating type frame riveting production line comprises a riveting moving platform, a riveting assembly rail device, a transfer rail device, a logic switch controller and a lifting transfer device; the lifting transfer device comprises an on-line lifting device and an off-line lifting device; the riveting assembly rail device, the off-line lifting device, the transfer rail device and the on-line lifting device are sequentially arranged and form a vertical quadrilateral structure. The riveting assembly rail device assembles the frame on line, the off-line lifting device lifts the riveting moving platform, the transfer rail device transfers the riveting moving platform, and the on-line lifting device descends the riveting moving platform, so that recycling of the riveting moving platform is achieved, the frame riveting assembly production efficiency is improved, the labor intensity is reduced, and the production efficiency is improved. The production environment is improved, the production cost is saved, and the production takt is stabilized; a vertical quadrilateral structure is adopted, the occupied area is small, and the occupied workshop space is effectively saved; the structure is simple and practicability is good.

Description

technical field [0001] The invention belongs to the technical field of vehicle frame assembly, in particular to a three-dimensional circulation type vehicle frame riveting production line and its operating method. Background technique [0002] The frame is a frame structure spanning the front and rear axles of the car, commonly known as the girder, and is the base of the car. It is generally composed of two longitudinal beams and several beams, and is supported on the wheels through the suspension device, front axle, and rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. The function of the frame is to support and connect the various assemblies of the car, so that each assembly maintains a relatively correct position, and bears various loads inside and outside the car. [0003] In the actual production and assembly process of the frame, the riveting trolley is usually used to support and assemble...

AI Technical Summary

Problems solved by technology

[0004] Manually pushing the riveting trolley will consume a lot of labor and increase the labor intensity of the operation; and the use of forklifts in the workshop has great safety hazards and also causes environmental pollution in the workshop; it will also lead to unstable production rhythms and low work efficiency; and today's In the production of frame assembly, a large workshop area will be occupied, and the effective use of workshop space cannot be realized
