Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically to a robotic automatic welding fixture for conveyor roller brackets. Background Technology

[0002] In modern production, conveyor roller supports are an important component of conveying equipment, and their production process requires precise welding operations.

[0003] Most existing welding fixtures for conveyor roller brackets are manually clamped for positioning and fixing. In traditional production, workers need to manually adjust the positioning module according to different models of roller brackets to achieve accurate welding positions. This process not only relies on the precision and experience of manual operation, but also requires a lot of time and effort. Especially when changing product models, the process of adjusting the positioning module is often very tedious, resulting in low production efficiency.

[0004] With the continuous development of flexible production models, especially under the demand for multi-model, small-batch production, the shortcomings of manual clamping methods have become more apparent. Firstly, the variability of manual operation makes fixture adjustments inflexible, prone to errors, resulting in inaccurate welding and affecting product quality. Secondly, the time-consuming nature of manual adjustments reduces the overall operational efficiency of the production line, failing to meet the demands of modern production for high efficiency and precision. No solutions have yet been proposed to address these technical problems. Utility Model Content

This enables rapid fixture module changeover, improving the flexibility of the production line. The fixture position can be quickly adjusted according to the needs of different product models, achieving efficient welding of multiple product models. This significantly shortens product changeover and adjustment time, improving production efficiency. Simultaneously, automatic handling grippers enable loading and unloading operations, achieving unmanned welding.
