Four-unit-linkage multi-axis flexible positioning system

Abstract

The invention discloses a four-unit-linkage multi-axis flexible positioning system which comprises a positioning platform. One side of the positioning platform is provided with two sets of rotary positioning units of positioning structures capable of being switched for positioning one side of a workpiece, the other side of the positioning platform is provided with two sets of three-dimensional movable positioning units capable of positioning the other side of the workpiece through three-axis linkage, and the three-dimensional movable positioning units can adjust positioning points in the transverse direction, the longitudinal direction and the vertical direction. The system further comprises a carrying device which grabs the workpiece and places the workpieces to the positioning platform for positioning. A gripper device for clamping the workpiece is detachably arranged on the carrying device. The four-unit-linkage multi-axis flexible positioning system adopts a single-axis linkage andthree-axis linkage combined way, and has the advantages of achieving four-unit linkage, being low in cost, easy to operate and wide in application range, and the like.

Description

technical field [0001] The invention relates to the field of flexible production of automatic welding of automobiles, more specifically, it relates to a four-unit linkage multi-axis flexible positioning system. Background technique [0002] With the increasing scale of automobile production, the globalization of market competition, the diversification and individualization of customers and market demands, and the relative excess of production, the life of products is getting shorter and shorter, and price competition is intensifying. , The mass production method is changing to the production method of multi-variety, small and medium batches and "variable variables", and the production method led by the producer is gradually changing to the production method led by the consumer, and the flexible manufacturing technology is to adapt to this transformation the best production method. [0003] At this stage, the flexible automobile production line has not yet formed a standard ...

AI Technical Summary

Problems solved by technology

[0003] At present, the flexible production line of automobiles has not yet formed a standard process mode. For different models, different manufacturers have to redesign the process and equipment each time, which leads to high design costs and poor process compatibility.

When it is necessary to increase the number of models, the original production line needs to be modified and designed, which is costly and time-consuming. This model will hardly meet the huge demand for automobiles in my country.

[0004] At present, although the intelligent flexible positioning system formed by multiple positioning units is applied to the automobile flexible welding production line of major OEMs, which improves the flexibility level of the automobile flexible production line to a certain extent, the positioning unit used in the existing positioning system All are driven by three-axis linkage, which is expensive, and the teaching and debugging are complicated, which limits the popularization and application of intelligent flexible positioning systems in automotive flexible welding production lines
