Roller system of a robot intelligent rolling hemming system

Abstract

The invention discloses a roller system of a robot intelligent rolling hemming system, which comprises a robot connecting flange, a main shaft is connected to the lower end of the robot connecting flange, a rolling head is installed at the end of the main shaft, and a plurality of rollers are installed on the rolling head. There are pressure sensor and driving spring, the pressure sensor checks and monitors the pressure of the driving spring, the driving spring is connected to the roller head, and directly responds to the working pressure of the roller head acting on the workpiece to ensure the quality of rolling hemming. In addition to the conventional rollers, the rolling head is also equipped with a wrapping corner knife, which can press the sharp corners of the inner and outer panels of the car. In the present invention, when the roller is pressed on the car parts, it will squeeze the compressed elastic part, and then make the compressed elastic part exert pressure on the roller head. Only by controlling the deformation of the compressed elastic part, the hemming working part can reach the actual The required rolling force ensures the quality of the hemming, and solves the problem that the traditional roller system is prone to pile up and wrinkle when the edge is pressed at the sharp corner.

Description

technical field [0001] The invention relates to a mechanical device, more specifically, to a roller system used in a robot intelligent rolling hemming system. Background technique [0002] With the increasingly fierce market competition, the continuous shortening of the automobile development cycle, and the continuous emergence of new models, the flexible and reconfigurable body production line technology is a new production mode developed for the production needs of small batches and multiple varieties in today's manufacturing industry. One of the key elements to shorten the automobile development cycle and improve product competitiveness. [0003] The robot hemming system can adapt to different characteristics of the work by making corresponding changes to the work program for different workpieces. When facing different processed parts, it can smoothly move along the contour of the workpiece to perform rolling hemming motion. It overcomes the problems that the hydraulic m...

Problems solved by technology

[0005] On the other hand, the current common roller system is composed of rollers of various shapes. ) The hemming angle caused by the hemming track of the robot has a great influence. For example, the roller system cannot be used for hemming at sharp corners, that is, 0° hemming, which needs to be completed by using a special push angle mechanism. If the hemming is forced, such piles will appear material phenomenon and cause poor quality, etc.
