Three-connecting-rod turnover mechanism

Abstract

The invention discloses a three-connecting-rod turnover mechanism. The three-connecting-rod turnover mechanism comprises a base, an air cylinder and an assembly thereof are rotatably arranged on one side of the base, a returning limiting device and two induction devices are arranged on the base, two induction devices are located on one side of the returning limiting device, a three-connecting-rodmechanism is arranged on the top of the base, a turnover assembly is arranged on one side of the three-connecting-rod mechanism, and a clamping limiting device is arranged on the bottom of the turnover assembly, and comprises a limiting pressing block and a limiting supporting block. The air cylinder is used for finishing the angle, required to be opened, of the two air cylinders, the heavier turnover assembly can be borne functionally, the buffer amount during unlocking and locking can be reduced, opening and locking are more smoothly achieved, through part turning welding precision, the surface measuring size can be better ensured, and meanwhile, the air cylinder and the assembly therefore can be mounted and fixed conveniently.

Description

technical field [0001] The invention relates to the technical field of sheet metal welding, in particular to a three-link turning mechanism. Background technique [0002] Sheet metal is sometimes called wrench metal. The word comes from the English platemetal. Generally, some metal sheets are plastically deformed by hand or die stamping to form the desired shape and size, and can be further processed by welding or a small amount of machining. To form more complex parts, the design of the sheet metal should ensure that the stamping process is simple, the stamping die is easy to make, the stamping quality of the sheet metal is high, and the size is stable, etc., while meeting the requirements of the product's function and appearance. The four most important aspects of the sheet metal process The steps are shearing, punching / cutting / , folding / rolling, welding, surface treatment, etc. Laser welding is mostly used for sheet metal welding, and the sheet metal parts need to be flip...

Problems solved by technology

[0003] The existing overturning mechanism has high requirements on the cylinder, and the damage rate is high. The long-term frequent use will cause a large loss to the cylinder. It needs spare parts for timely replacement and maintenance, resulting in dynamic load (inertial force), and it is not easy to balance, so it is not suitable for High speed, complex design, and difficult to achieve precise trajectory, so we proposed a three-link flip mechanism to solve the above problems
