Vehicle headlamp assembly simulation loading detection device

Abstract

The invention discloses a vehicle headlamp assembly simulation loading detection device. The device is characterized in that the device comprises a horizontal supporting base plate, a supporting guide column, a pressing pin, a pressing module, an analog block and a headlamp assembly. The position, shape, size and quantity of the analog block are determined according to the requirements of a vehicle model digital model. The space size of the headlamp assembly loading is determined. The loading size is used as the design basis. Three-dimensional design software is used for sub-module design. A detection device digital model is established. Processing data are successively extracted according to modules. Sub-module data input and processing are carried out on a numerical control machining center. One end is fixedly arranged on the horizontal supporting base plate. The analog block is fixedly arranged on the other end, and the position, height and quantity are designed according to the position, shape, size and quantity of the analog block. The device provided by the invention has the advantages that the assembly gap and surface difference of the headlamp assembly are consistent with the lamp assembly.

Description

technical field [0001] The invention relates to the field of automobile engineering, and more specifically relates to a simulated loading detection device for an automobile headlamp lamp assembly. Background technique [0002] With the development of automobile engineering technology, the manufacturing technology of automobile lamps has been transformed from the traditional stamping process to the injection molding process, which means that the main parts of the lamp, such as the lamp housing, lamp glass, BMC reflector and auxiliary dimming structural components, all lamps use It is processed by injection molding of engineering plastics. Lamps adopt injection molding process. Due to the influence of pressure, temperature, humidity and other factors, the injection molding process of the main parts of the lamp housing and lamp glass is prone to deformation. The gap and surface difference between the lamp assembly and the body sheet metal loading will change, causing the lamp ...
