Conductive device

Abstract

The invention discloses a conductive device, which comprises an insulating base and a conductive connecting rod, wherein a first groove is formed in the upper end part of the insulating base; a conductive copper bar is arranged in the groove; an opening which is communicated with the groove is formed in the lower end part of the insulating base; a second groove is formed in the center position of the lower end part of the conductive copper bar along the axial direction; one end of the conductive connecting rod passes through the opening and enters the second groove to contact the conductive copper bar; and a compression spring is arranged on the conductive connecting rod between the lower end part of the conductive copper bar and the bottom part of the first groove. Acting force is applied to the conductive copper bar through the compression spring; the condition that the conductive copper bar is in contact with the lower surface of a tooling through elastic action even if the upper end surface of the conductive copper bar is abraded is ensured when the conductive copper bar is in contact with the tooling; and the service lifetime of the conductive device can be further prolonged by adjusting the penetration length of a conductive bolt under the condition of relatively large abrasion of the conductive copper bar.

Description

technical field [0001] The invention relates to a conductive device, which belongs to the technical field of robot welding. Background technique [0002] During the welding process of the robot, it is necessary to conduct electricity to the tooling. The existing conductive method usually uses a conventional conductive brush to contact the outer peripheral surface of the tooling to conduct electricity to it. However, during the welding process, the tooling needs to be continuously rotated. The conductive brush will wear the contact surface during the long-term friction process of the tooling. After a long period of wear, it will not only affect the conductive effect, but also easily cause damage to the motor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a conductive device, which applies a force to the conductive copper rod through a compression spring to ensure that the conductive copper rod is in contact with...
