Novel numerical control rolling taping machine

Abstract

The invention discloses a novel numerical control rolling taping machine which together finishes the taping process of the inner and outer plate flanges of a vehicle body covering piece through the triaxial linkage of a worktable and the shape following rotation of a rolling roller power head, comprises the basic principle and the detailed structure of a numerical control rolling machine tool and complementally explains the process characteristic and the basic process of the numerical control rolling machine tool. The invention aims at simplifying the taping process and the taping mould design of the flanges of the traditional vehicle body covering piece, improving the taping efficiency and lowering the taping cost. The machine tool only needs to carry out numerical control programming for different taping paths, can carry out taping for the inner and outer plates of various vehicle body covering pieces in multiple vehicle types without needing a special tool except for matching with a taping mould with a corresponding structure according to the shapes of different vehicle body covering pieces and can simultaneously finish a plurality of technical processes of loading and unloading, seal coating, taping, welding and the like by adopting one numerical control rolling machine tool, the automation of equipment and the flexibility degree of the taping process are improved, and the equipment can be very convenient to popularize and apply due to the universality of a numerical control system.

Description

technical field [0001] The invention relates to a structural design of a novel numerically controlled rolling edge wrapping machine and a characteristic description of a process method thereof. Background technique [0002] Hemming is a common processing method for connecting the outer panel and inner panel of automobile body parts, and is an important assembly process for door assemblies (such as doors, covers, etc.). Traditional hemming methods mainly include manual hemming, hydraulic special hemming machine hemming and molded hemming. Manual hemming has low production efficiency, poor product appearance quality, high labor intensity and high noise, and has been eliminated. For the edge wrapping of the hydraulic special edge wrapping machine, the pre-flanging and flanging pressing are performed in sections, resulting in poor pressing quality of the segmented joints. Now large automobile factories and car factories with high appearance quality requirements do not use this ...

AI Technical Summary

Problems solved by technology

Tandem robots move flexibly, and it is relatively easy to realize hemming movement. So far, most of the robot hemming technology adopts tandem robots, but its cantilever beam structure reduces the rigidity of the equipment, thereby affecting the quality of the pressing and forming of the panel, such as The periphery is not smooth, wrinkled, etc.

On the other hand, the articulated structure of the series robot causes the transmission and accumulation of errors, so the trajectory accuracy is low. At present, a few researchers have proposed the idea of ​​using parallel robots as the hemming workbench to realize the robot hemming process, but The working space of parallel robots is small, and it is expected that there may be certain restrictions in actual work
