Description

Automotive Fixtures for Precise Positioning of Rotary Platforms

technical field

The utility model relates to a rotating platform, in particular to an automobile fixture for precise positioning of the rotating platform, which belongs to the technical field of fixtures.

Background technique

With the progress and development of the times, the field of auto parts welding is becoming more and more mature, and the pressure of competition is also increasing. How can domestic automobiles compete with foreign automobiles, and how should domestic automobile manufacturers survive and appear among many enterprises? Advantages, first of all, are inseparable from the control of cost, quality and efficiency.

In the past, the welding of domestic auto parts was mostly manual welding. With the advancement of technology, robot welding has gradually replaced manual welding, but the current robot welding equipment mostly uses single-station welding or double-station welding. If you want to weld multiple varieties or multiple workpieces, you can only replace the fixture, or add new welding equipment to meet the survival rate. This method not only has a long production cycle, but may even increase the cost.

If a robot can weld multiple stations, it can effectively avoid cost waste and save the pain of frequent fixture replacement. In order to achieve accurate positioning of multiple stations, we need a rotating platform with precise positioning. However, most of the current turntables are imported from abroad, with high cost and long delivery cycle. Although they can achieve high precision, they have limited load capacity.

In summary, it is very necessary to develop a rotary platform with high cost performance, high bearing capacity, accurate positioning, and multi-station welding.
