Description

Technical Field

[0001] The utility model belongs to the technical field of feeding equipment, and particularly relates to a multi-station feeding device. Background Art

[0002] A numerically controlled machine tool is an automated machine tool equipped with a program control system. This control system can logically process a program with control codes or other symbolic instructions, decode it, represent it in coded numbers, and input it into the numerical control device through an information carrier. After arithmetic processing, various control signals are sent out by the numerical control device to control the actions of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. The numerically controlled machine tool better solves the problems of processing complex, precise, small-batch, and multi-variety parts. It is a flexible and high-efficiency automated machine tool, representing the development direction of modern machine tool control technology and being a typical mechatronic product.

[0003] In the existing production line processing, it is necessary to convey the workpieces to the front of the machine tool through a conveyor belt, and then install and fix the workpieces on the workstations of the numerically controlled machine tool for processing. In the existing technology, one machine tool corresponds to only one set of feeding devices. When multiple machine tools are processing simultaneously, multiple sets of feeding devices are required, occupying a large area and easily causing the production workshop to be too compact. At present, there are also multi-station conveyors that can achieve the operation of multiple workpieces simultaneously, saving time and effort. However, the existing conveying devices do not separate multiple workpieces during the multi-station workpiece conveying process, and interference is likely to occur during feeding.
