Description

Technical Field

[0001] The utility model relates to the technical field of friction welding machine manufacturing, in particular to a jaw clamp synchronization mechanism for a friction welding machine. Background Art

[0002] In modern industrial production, friction welding technology is widely used due to its advantages such as high efficiency and reliability. During the operation of the friction welding machine, the jaw clamp is responsible for the high-precision clamping of the workpiece to be welded. When the jaw clamp is working, its left and right moving bodies need to move synchronously toward the center to clamp the workpiece. Therefore, the stability of the synchronization mechanism and the repeatability of the positioning accuracy are directly related to the stability of the jaws. For this reason, we have developed a jaw clamp synchronization mechanism for friction welding machines.

[0003] At present, during the operation of some friction welding machines, if the jaw clamp has difficulty in clamping the welding workpiece with high precision, it is likely to reduce the working accuracy and repeatability of the jaw clamp, thereby causing problems such as precision deviation during the welding process.

The other ends of the long connecting rods are hinged on the top surface of the short connecting rods and are arranged on the outside of the first connecting shafts that pass through the bottom surface.

The other end of the long connecting rod is hinged on the top surface of the short connecting rod and is arranged on the outside of the first connecting shaft that passes through the bottom surface. Under the synchronous movement, the short connecting rod connected to the outside of the central axis rotates. This combination realizes a simple structure and high operating precision, greatly improves the working precision and repeat positioning precision of the jaw clamp, and solves the problem that if the jaw clamp is difficult to clamp the welding workpiece with high precision, then the working precision and repeat positioning precision of the jaw clamp will be reduced, thereby causing precision deviation and other problems during the welding process.
