Self-adaptive binding tool

Abstract

The invention discloses a self-adaptive binding tool. The self-adaptive binding tool comprises a connecting base plate, a group of edge covering cylindrical wheels, a group of auxiliary cylindrical wheels, an auxiliary wheel sliding table and an edge covering wheel sliding table, and the auxiliary wheel sliding table and the edge covering wheel sliding table are arranged at the lower end of the connecting base plate; and the auxiliary cylindrical wheels are connected with a first sliding block on the auxiliary wheel sliding table through a first connecting assembly, and the edge covering cylindrical wheels are connected with a second sliding block on the edge covering wheel sliding table through a second connecting assembly, so that the gaps between the auxiliary cylindrical wheels and the edge covering cylindrical wheels can be adjusted to adapt to forming dies and plates of different thicknesses. According to the self-adaptive binding tool, two groups of roller sets are connected to a connecting disc, the two groups of roller sets can axially move by means of sliding rails and sliding blocks, a gap between the two groups of roller sets can be conveniently changed, edge covering of the forming dies and the plates between the two groups of roller sets can be conveniently completed in three steps after the two groups of roller sets are oppositely clamped, and the edge covering quality is improved; and meanwhile, a proportional valve capable of controlling output pressure of an air cylinder is additionally arranged, the proportional valve is operated, different edge covering forces for pre-edge covering and final edge covering can be provided, and the edge covering effect is improved.

Description

technical field [0001] The invention relates to the technical field of automobile sheet metal hemming equipment, in particular to an adaptive hemming tool. Background technique [0002] Hemming tools, combined with robotic hemming and pressing technology, have been applied to the hemming of key components of car body-in-white, such as roof sunroofs, engine hoods, luggage compartment covers, doors, fenders and wheel covers, etc. [0003] At present, the development of hemming technology is relatively mature, but limited by specific projects, when hemming tools are applied to specific projects, the gap between the two roller sets is not easy to adjust, and the error tolerance rate for the hemming of the membrane plate after positioning is low. Quality problems are prone to occur, and the output pressure of the cylinder cannot be adjusted during hemming, making the hemming force of pre-hemming and final hemming uncontrollable, affecting the hemming effect, and there is room for...

Problems solved by technology

[0003] At present, the development of hemming technology is relatively mature, but limited by specific projects, when hemming tools are applied to specific projects, the gap between the two roller sets is not easy to adjust, and the error tolerance rate for the hemming of the membrane plate after positioning is low. Quality problems are prone to occur, and the output pressure of the cylinder cannot be adjusted during hemming, making the hemming force of pre-hemming and final hemming uncontrollable, affecting the hemming effect, and there is room for further improvement and optimization

[0004] In the prior art, when the hemming tool is applied to a specific project, the gap between the two sets of rollers is not easy to adjust because the two sets of rollers are not on the same connecting plate. , affecting the quality of hemming; and the output pressure of the cylinder cannot be adjusted during hemming, resulting in the uncontrollable hemming force of pre-hemming and final hemming, which directly affects the hemming effect
