Automobile door assembly fixture

Abstract

The invention provides an automobile door assembly fixture. The automobile door assembly fixture comprises a fixture machine body module, driving modules, a positioning clamping module and a controller, wherein the fixture machine body module comprises a rack module and a frame module, an indexing mechanism in the rack module can realize revolving movement of the frame module, one main body of therack module adopts an inverted 'T' shaped structure, one main body of the frame module adopts a structure shaped like a Chinese character 'zhong', and the assembly fixture operation process stabilityis improved; the driving modules are controlled by servo motors and can precisely control the movement amount of an automobile door in the horizontal and vertical directions, meanwhile, the installation angle between the first driving module and the second driving module inside the driving modules is adjusted, any two-dimensional direction reciprocating movement of the automobile door is realized, the debugging cycle is shortened, and the assembly consistency is guaranteed; and the positioning clamping module adopts a flexible development design, an automobile door positioning component, an automobile body positioning component and a vacuum suction cup component can be moved and replaced inside a positioning clamping frame or respective sliding rails, and the universality of the automobile door assembly fixture is enhanced.

Description

technical field [0001] The invention relates to the field of automobile assembly fixtures, in particular to an automobile door assembly fixture. Background technique [0002] The car body is usually made of complex thin-plate parts, which are spliced ​​by welding, screwing, gluing and other processes. The thin-plate parts are affected by the material, thickness, stamping process, and stamping die during the stamping process, making it difficult to accurately control the quality of the parts. At the same time, in the production welding process, there are many welding spots, welding positioning points, welding stations and welding deformation of parts, which makes it difficult to control the assembly accuracy of the whole vehicle. It not only affects the overall vehicle performance of the car, such as NVH, handling stability, braking, ride comfort, etc., but also brings bad driving experience to users. [0003] The car door is a key part of the car body. The quality of its as...
