Abstract
Description
Technical Field
[0001] The utility model relates to the field of clamps, and more specifically, to a flexible positioning clamp. Background Art
[0002] In the automotive industry, due to cost and design style considerations, the shapes of parts for many similar models are relatively small and roughly similar. The cost of developing corresponding fixtures and grippers for each model of parts is high, and adjusting the production line is also more complicated. The debugging process will take up a lot of time, which is not conducive to reusing the production line to produce similar parts of various specifications.
[0003] Based on the deficiency of the prior art that a corresponding clamp gripper needs to be designed for each spare part, the present application proposes a flexible positioning clamp, which makes the positioning clamp highly flexible and can adapt to spare parts of various specifications online, thereby improving the flexibility of the production line. In the process of replacing production spare parts, there is no need to load and unload the clamps on the production line. Only simple adjustments are required to complete the adaptation to the new specifications of spare parts. It even supports spare parts of multiple specifications, and can adapt to more spare parts specifications with a smaller number of clamp grippers. Summary of the invention
