Edge covering and pressing automation system for vehicle door water trimming of vehicle Body in White

Abstract

The invention provides an edge covering and pressing automation system for vehicle door water trimming of the vehicle Body in White. The edge covering and pressing automation system comprises two HZ-type special hydraulic cylinders, the HZ-type special hydraulic cylinders are hinged to a supporting piece and hinged to turnover plate connecting pieces through bulb matchers, and the turnover plate connecting pieces are hinged to the supporting piece and fixedly connected with a turnover plate; the two HZ-type special hydraulic cylinders are connected with a gas-liquid reinforcement cylinder, thegas-liquid reinforcement cylinder is connected with an outer high-pressure gas source, the gas-liquid reinforcement cylinder and the HZ-type special hydraulic cylinders are connected with a control unit in a main control system, and two position sensors are connected with a detection unit in the main control system. According to the edge covering and pressing automation system, signals are sent through the main control system, the HZ-type special hydraulic cylinders drive the turnover plate to rotate, and after edge covering work is finished, the edge covering and pressing automation system is restored to enter next-time circulation. The edge covering and pressing automation system has the advantages that the debugging period is short, the production speed is high, the edge covering effect is good, and less maintenance is needed in the later period.

Description

technical field [0001] The invention belongs to the field of automobile body-in-white manufacturing equipment, and relates to an automatic system for water-cut edge wrapping and pressing of a door of an automobile body-in-white, which is applied to the edge wrapping and pressing work of the water-cut edge area of ​​a car door during the manufacturing process of a body-in-white. Background technique [0002] In the traditional robot hemming production mode, the hemming and pressing work of the water trimming area of ​​the door is generally completed by the robot holding the tool end according to the established procedure. However, due to the inherent defects of the robot hemming process, during the rolling process, parts The rolling edge pressure will not be exactly the same, and the thickness of the water-cut edge of the panels after pressing will be inconsistent, resulting in difficulties in the subsequent installation and adjustment of the door water-cut edge trim, and prob...

[0002] In the traditional robot hemming production mode, the hemming and pressing work of the water trimming area of ​​the door is generally completed by the robot holding the tool end according to the established procedure. However, due to the inherent defects of the robot hemming process, during the rolling process, parts The rolling edge pressure will not be exactly the same, and the thickness of the water-cut edge of the panels after pressing will be inconsistent, resulting in difficulties in the subsequent installation and adjustment of the door water-cut edge trim, and problems such as abnormal door noises; due to the different door designs of different models, there will be operating space in the door water-cut edge area Changes increase the difficulty of robot trajectory debugging; some areas cannot meet the minimum operating space requirements of the robot tool end, and quality defects such as edge defects and flash edges will occur
