Abstract

The invention provides an automobile trimming device, and belongs to the technical field of machinery. The problem that an existing automobile trimming device cannot guarantee the stability of a driving part while guaranteeing the trimming precision is solved. The automobile trimming device comprises a shell and a trimming head used for metal plate trimming, the trimming head is slidably connected into the shell through a guide rail assembly, a driving part capable of driving the trimming head to slide is further fixed into the shell, a supporting air cylinder is further fixed into the shell, a piston rod of the supporting air cylinder is arranged in the length direction of the guide rail assembly and connected with the trimming head, and the guide rail assembly is located on the side of the driving part and close to the driving part. The supporting air cylinder counteracts gravity component force generated when the trimming head is in an inclined state, the guide rail assembly and the supporting air cylinder are matched to support the trimming head, the inclination angle of the trimming head in trimming work is limited, the driving part is stably stressed, and the stability of the driving part is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an automobile hemming device. Background technique [0002] The side door opening area of ​​a car is an important part of the car body. Generally, the outer sheet metal wraps the inner sheet metal structure, wherein the outer sheet metal is made of aluminum material, and the inner sheet metal is made of steel material. In the prior art, the spot welding connection or SPR self-piercing riveting connection is most commonly used for the assembly of the side wall door opening area, but the spot welding connection method cannot be applied to the structure of the aluminum outer plate wrapping the inner plate, and the SPR self-piercing riveting The connection is limited by the width and thickness of the overlap in the door opening area and will not work well. [0003] In this regard, it can be considered to use the hemming process for hemming. As one of the hemming processes, hemming i...
