Description

Technical field: [0001] The invention relates to the field of numerical control lathes, in particular to an automatic loading and unloading and transmission device used in a production line composed of multiple inverted numerical control lathes. Background technique: [0002] With the continuous development of equipment manufacturing technology, the demand for bearings from all walks of life is increasing, and its technical requirements are getting higher and higher, which makes the trend of general bearing specialization more and more obvious. The existing bearing processing equipment is mostly horizontal CNC lathes. However, due to the clamping accuracy and the limitation of the turning radius of the lathe, the horizontal CNC lathe has been very effective when machining medium and large bearing rings with a diameter of 100-400mm. Difficult. Especially when the horizontal CNC lathe is processing high-strength metal materials above Φ200mm, due to the vertical installation of the ...

AI Technical Summary

Problems solved by technology

Most of the existing bearing processing equipment is a horizontal CNC lathe. However, when machining medium and large-sized bearing rings with a diameter of 100-400 mm, due to the limitation of the clamping accuracy and the radius of rotation of the lathe, the horizontal CNC lathe is very difficult. incompetent

Especially in the process of processing high-strength metal materials with a horizontal CNC lathe above Φ200mm, since the workpiece is installed vertically, the weight of the workpiece has a significant impact on the clamping accuracy, and its chip removal is easy to scratch the surface of the workpiece, plus It is more complicated to realize automatic loading and unloading, so the idea of ​​using an inverted CNC lathe to process medium and large-sized bearing rings is proposed

However, since the medium and large size bearing rings not only require high processing accuracy, but also have many processing surfaces, if the entire processing process is realized on an inverted CNC lathe, it is necessary to load and unload multiple times and replace different tools and fixtures

In order to improve efficiency, it is necessary to form a flexible manufacturing unit of multiple inverted CNC lathes to realize assembly line operations, that is, to process some surfaces of bearing rings on one inverted CNC lathe, and then transfer the workpiece to another inverted CNC lathe for the rest. Surface processing, but there is currently a lack of equipment that reliably realizes this conveying process and realizes the process connection
