Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings, but does not constitute any limitation to the present invention. Similar component numbers in the accompanying drawings represent similar components. As mentioned above, the present invention provides a flexible electrode and a welding fixture for maintaining the position of the workpiece. The present invention can be installed on an industrial assembly line to realize welding of cap nuts. The fixture can automatically adapt to the size of the cap nut. The flexible electrodes realize the opening and closing of the gripper, and generate a stable, flexible, and uniform gripping force, while reducing the requirements on the control system.

[0033] In this embodiment, the working process and principle of the flexible electrode and the welding jig for maintaining the position of the workpiece in the present invention are described by taking the grasping of a cylindr...

Abstract

The invention relates to a fixture, in particular to a flexible electrode welding fixture for keeping the position of a workpiece. The flexible electrode welding fixture for keeping the position of the workpiece is characterized by consisting of a flexible electrode and a fixture, wherein the workpiece is arranged in the fixture; the flexible electrode is positioned above the fixture and the workpiece; the fixture comprises a spring, a bracket, a first pin, a second pin, a cover plate, a first finger and a second finger; a first rotating hole of the first finger and a second rotating hole of the second finger are connected to the first pin in a movable mode; the cover plate is fixedly connected to the bracket and is arranged above the first finger and the second finger; and the flexible electrode comprises a main electrode body, an electrode contact, an electrode sleeve, a contact and a spot welding spring. The fixture can adapt to the size of a cap nut automatically, the fingers can be opened and closed flexibly, stable and uniform grabbing force can be generated, and requirements on a control system can be reduced at the same time.

Description

technical field [0001] The invention relates to a spot welding device, in particular to a workpiece positioning device for spot welding and an electrode for spot welding processing. Background technique [0002] Welding is a processing method that achieves atomic bonding and non-detachable connection of workpieces by heating and (or) pressure. Including fusion welding, pressure welding, brazing and so on. During the welding process, the workpiece and the solder melt to form a molten zone, and the molten pool cools and solidifies to form a connection between the materials. During this process, pressure is usually required. There are many sources of energy for welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. The earliest modern welding technology appeared at the end of the 19th century, first arc welding and oxygen gas welding, and later resistance welding. In the early 20th century, with the first and second world wars, there...
