Variable Angle Robot Hemming Tool

Abstract

The invention discloses a changeable-angle robot edge rolling tool. The changeable-angle robot edge rolling tool is characterized in that a robot connection framework is arranged, a first hinge is arranged at the upper part of the robot connection framework, and an upper cylinder is mounted on the first hinge by means of a rod end of a piston rod of the upper cylinder, so that the upper cylinder can swing on the first hinge in a manner of taking the hinge axis as a center; a lower cylinder is mounted through a connecting plate in a manner of being back-to-back to the upper cylinder, the lower cylinder is connected with the tail of a connecting rod through a second hinge by means of a rod end of a piston rod of the lower cylinder, the front end of the connecting rod is connected with the robot connection framework through a third hinge, and a roller wheel is fixedly arranged on the front end face of the connecting rod. According to the changeable-angle robot edge rolling tool, the angle change of the roller wheel arranged at the front end of the connecting rod is realized by using the upper cylinder and the lower cylinder which are mounted back to back, so that the posture change of a robot during edge rolling is reduced greatly, the difficulty of the design of fixtures is lowered effectively, and the movement efficiency of the robot is increased.

Description

Technical field [0001] The invention relates to a robot hemming tool, in particular to a robot hemming tool capable of changing the angle of a roller as required; it is applied to the hemming of the inner and outer panels of the front and rear doors of the car body in white, the engine compartment cover, the trunk cover or the back door . Background technique [0002] With the control of the input cost of the automobile OEMs, the press hemming process gradually fades out of the body door cover and other parts of the hemming process due to the high one-time investment and poor flexibility. Compared with the robot hemming system, the one-time investment is less. The advantages of high flexibility, low maintenance cost, etc. have gradually attracted the attention of various automobile OEMs. [0003] In the robot hemming system, the robot is used as a motion drive component, and the hemming tool is installed at the end of the robot as the execution part of the hemming; in the robot he...

Problems solved by technology

In the prior art, since the flanging of each step of 30°-50° is realized by changing the attitude of the robot, the robot needs to change its attitude many times during the entire hemming process, causing interference with the hemming fixture and the robot reduction in movement speed

Therefore, in order to avoid interference, it is necessary to carry out repeated verification during design, and sometimes it cannot be realized, resulting in changes to products or sacrificing quality to meet manufacturing requirements.
