Automobile door taping machine

Abstract

The invention discloses an automobile door taping machine. A pre-taping module and a taping module of the automobile door taping machine are provided with working faces which are matched with automobile door pre-taping molded surfaces. Two ends of the pre-taping module and two ends of the taping module are provided with rotary shafts respectively. The rotary shafts are arranged on bearing blocks which are arranged at two ends of each edge of a die block. The pre-taping module and the taping module are respectively driven by a first actuating device and a second actuating device and rotate around the rotary shafts of the pre-taping module and the taping module. The pre-taping module and the taping module are arranged in a separating mode and are controlled by independent actuating devices, so that the whole structure is reasonable, dismantling becomes convenient, and mold repairing quantity of the pre-taping module and the taping module is greatly reduced. Due to the fact that a rolling mechanism which guides a clamping device to move up and down and can adjust gaps automatically is arranged on the clamping device, work of the clamping device is stable and reliable, a chattering phenomenon generated when the clamping device works is restrained effectively, and positioning error is reduced.

Description

technical field [0001] The invention relates to workpiece processing equipment, in particular to an edge wrapping machine for automobile doors. Background technique [0002] The existing car door hemming machine was successfully developed by us in China in 1989, and it is widely used by many domestic car factories. It has made outstanding contributions to the development of China's automobile industry; however, the positioning and clamping device of the hemming machine is to position and clamp the door to be hemmed from the side, so that the door to be hemmed will be unevenly stressed and positioned during the working process. Accurate; the existing hemming machine uses many pre-hemming modules and hemming modules to hem one side of the car door at the same time when hemming, and presses the bending part of the door to be packaged inwards to complete the hemming. This hemming method makes the inner surface of the hemming part uneven, especially at the joints of the two modu...

[0002] The existing car door hemming machine was successfully developed by us in China in 1989, and it is widely used by many domestic car factories. It has made outstanding contributions to the development of China's automobile industry; however, the positioning and clamping device of the hemming machine is to position and clamp the door to be hemmed from the side, so that the door to be hemmed will be unevenly stressed and positioned during the working process. Accurate; the existing hemming machine uses many pre-hemming modules and hemming modules to hem one side of the car door at the same time when hemming, and presses the bending part of the door to be packaged inwards to complete the hemming. This hemming method makes the inner surface of the hemming part uneven, especially at the joints of the two modules, which are prone to wrinkles, the corners are neither smooth nor tight, and the periphery of the workpiece is not smooth. At the same time, the structure of the original hemming machine is complex. , the installation is difficult, the installation positions of the pre-wrapping module and the hemming module are mutually restrained, especially the workload of assembly, debugging, and mold repair is too large, and it is difficult to repair to the ideal state. The workpiece ejection device of the original hemming machine is The separated type is difficult to install and debug, and the workpiece is not smooth up and down, often stuck and shaken
