Heavy-load RGV system for flexible production line

Abstract

The invention discloses a heavy-load RGV trolley system for a flexible production line. A trolley base body assembly is connected to a ground rail through a linear guide rail and a sliding block and is driven by a motor and driven by a gear and a rack to walk in the direction of the ground rail; the extending assembly is connected to the trolley base body through a linear guide rail and a sliding block, horizontally extends out in the direction perpendicular to a ground rail through motor driving and gear and rack transmission, and is in lap joint with a machine tool workbench. The chain transmission assembly achieves rotation of a dragging pin on a chain through transmission of a motor and a chain wheel fixed to the extending assembly. A tool and a workpiece are arranged on the upper portion of the tray assembly, and a guide mechanism is arranged at the bottom of the tray assembly. The machine tool workbench is provided with a zero point positioning unit, a hydraulic lifting assembly and a lifting guide limiting assembly. Hydraulic cylinders of the hydraulic lifting assemblies operate synchronously to enable blind rivets at the bottom of the tray to be stably disengaged from the zero point or fall into zero point positioning holes. According to the automatic feeding and discharging device, automatic feeding and discharging can be achieved for parts large in appearance size and heavy in weight.

Description

technical field [0001] The invention belongs to the field of industrial automatic processing and manufacturing, and relates to a heavy-duty RGV trolley system used for loading and unloading on a flexible production line. Background technique [0002] With the rapid development of intelligent manufacturing, automated production lines are widely used in manufacturing and assembly processes, especially in recent years, flexible automated production lines for multiple varieties and small batches have been favored by many companies. The use of flexible automatic lines can achieve 24-hour non-stop production, can be compatible with more products, can flexibly schedule production, trace processing information, and perform information statistics. [0003] For most products with small dimensions and light weight, the loading and unloading methods are generally more flexible, and six-axis robots, RGV trolleys, trusses, etc. can be used for loading and unloading; but for parts with lar...

Problems solved by technology

[0003] For most products with small dimensions and light weight, the loading and unloading methods are generally more flexible, and six-axis robots, RGV trolleys, trusses, etc. can be used for loading and unloading; but for parts with large dimensions and heavy weight, the It is extremely limited. The load of a general industrial robot is about 1 ton. Even for a robot with a specific large load, the arm span is difficult to meet the production needs. As a result, many companies with large product specifications want to try automatic processing but cannot achieve it.
