Electrode coping and replacing all-in-one machine

Abstract

The invention discloses an electrode coping and replacing all-in-one machine which is used in the field of electrode coping and replacement in an automobile automatic welding production line. The electrode coping and replacing all-in-one machine comprises a machine frame, a drive machine head arranged on the machine frame, an electrode coping unit and an electrode cap replacing unit, wherein the electrode coping unit and the electrode cap replacing unit are arranged on the drive machine head. The drive machine head is provided with a servo motor used for driving the electrode coping unit and the electrode cap replacing unit. According to the electrode coping and replacing all-in-one machine, the electrode coping unit and the electrode cap replacing unit on the drive machine head are driven through the servo motor, coping of an electrode and replacement of an electrode cap can be completed and automation and integration of the coping and the replacement of the electrode cap can be achieved. Meanwhile, due to integration of device functions, the technical problem that the automobile automatic welding production line is stopped for electrode cap replacement is solved and automatic degree of the automobile automatic welding production line and production capacity of automobiles are improved.

Description

technical field [0001] The invention is used in the field of electrode grinding and replacement for automatic welding production lines of automobiles, and in particular relates to an electrode grinding device which integrates two functions of collector automatic grinding and automatic replacement. Background technique [0002] At present, modern automobile production lines generally use robots for spot welding of automobile body-in-white. The intelligent high-speed movements of robots can meet the high production capacity requirements of automobile production, but the electrodes used for welding are frequently switched on and off and pressure is applied during robot welding. The electrode wears quickly, and the surface of the electrode is easy to form an oxide layer, which will damage the electrode. The damaged electrode will seriously affect the welding quality of the body in white. In order to eliminate the electrode wear and the adverse effect of the electrode oxide layer ...

AI Technical Summary

Problems solved by technology

[0004] Although the existing electrode grinding adopts the automatic grinding controlled by the robot, its function is single, the replacement of the electrode cap needs to be done manually, and the replacement of the electrode cap takes a long time

During the replacement of the electrode caps, the automobile welding production line needs to stop for several minutes. Since the electrode caps of each welding machine are replaced at different time periods, this will prevent the welding production line from being fully continuous, and the production capacity of the automobile will be affected to a certain extent.

[0005] At present, regarding the replacement management of electrode caps, although there are some scientific methods, such as flexible grouping of electrodes and centralized replacement of electrode caps of the same group of welders, this method can reduce the stoppage of automobile production caused by electrode cap replacement. The number of lines can reduce the total time of car production stoppages, but it cannot completely avoid the phenomenon of car production stoppages caused by the replacement of electrode caps
