Abstract

The invention belongs to the technical field of automobile equipment manufacturing, and particularly relates to tightening equipment. The automatic tightening equipment comprises a main body base frame, a tightening gun, a movable assembly and a quick-change disc, wherein the tightening gun is used for tightening a bolt; the movable assembly drives the tightening gun to do linear motion; the quick-change disc is used for being detachably connected with a robot; the movable assembly and the quick-change disc are both fixed on the main body base frame; the tightening gun is fixed on the movable assembly; and after the robot connected with the quick-change disc drives the tightening gun to move to a preset body-in-white tightening hole position, the movable assembly is driven to do linear motion through a preset tightening stroke, then the tightening gun is driven to rotate, and the tightening gun is driven to automatically tighten the bolt on a tightening station. According to the automatic tightening equipment, the tightening gun can be firmly fixed, not only can the strength of the tightening gun be guaranteed, but also the precision of the tightening gun can be guaranteed, and the purpose of automatic nailing of the robot is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile equipment manufacturing, and in particular relates to a tightening device. Background technique [0002] The connection process of tightening bolts is a new connection method in the body shop. Under certain conditions, it can replace the connection that cannot be completed by spot welding. For example, the connection of four-layer board and above, the connection under the cavity, etc., cannot be completed by spot welding, but the connection can be realized by tightening bolts. [0003] The existing tightening guns can only be manually operated and cannot be fixed on the robot, that is, the automatic tightening of the robot cannot be realized in the automobile welding workshop. Contents of the invention [0004] The invention aims at providing an automatic tightening device aiming at the technical problem that the connection can only be realized by manual operation when using a tightening gun...
