Abstract

The invention relates to a modularizing self-adaptation adjusting clamp used in the automobile welding, comprising a based station(1), a clamping mechanism(100) fixed on the based station(1) , an independent principal positioning mechanism(200), and an online real-time detecting and self-adaptation adjusting device(300). The online real-time detecting and self-adaptation adjusting device (300) is composed of a stepping motor (305), a slider (308), a straight-line guiding rail (309) and a transmission device. The transmission device, which is driven by the stepping motor (305), pushes a pushing rod (301) and the slider to slide along the straight-line guiding rail (309). The invention is more flexible and is convenient for the connection and combination of every component by means of modularized, standardized and serialized clamp elements, can be adapted to various work within a certain range and type, can effectively reduce the manufacturing cost, effectively controls the precision of the key points of workpieces and improves the welding quality and efficiency.

Description

technical field [0001] The invention belongs to the field of automobile welding, in particular to a modular self-adaptive adjustment component and an adjustment method thereof. Background technique [0002] The competition among automobile manufacturers in the 21st century has evolved into a competition based on time. In order to meet the requirements of the market on product diversity, quality, and delivery time, it is necessary to study and analyze the body manufacturing system from the perspective of improving quality and flexibility, and to find effective solutions. control method. Statistics show that 67%-70% of all design changes made by automobile manufacturers are caused by product size deviations. The lack of effective control of production process performance and deviations during product process design is the basic cause of the problem. Due to the easy deformation of thin plate stamping parts, the part dimensional deviations caused by the stamping quality of part...
