Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding devices, in particular to an automatic feeding device for a numerically controlled flat milling machine. Background Art

[0002] A flat milling machine is a special machine tool belonging to the secondary processing machine series. It is used for flat milling symmetrically on two surfaces and is mainly used for end face milling and slot milling of shaft parts and rod parts, such as D-shaped surfaces, parallel surfaces, slots, parallel slots, etc. Most flat milling machines on the market today are large in size, complex in structure, and have high manufacturing costs. At the same time, during the loading process, manual loading is required, and the materials are manually placed in the fixture and clamped and fixed using the fixture, which is time-consuming and labor-intensive, greatly reducing work efficiency. For example, the patent (CN115301991A) discloses a fully automatic precision hardware flat milling machine. The feed cylinder drives the four corner bars to move along the guide slide to realize automatic loading of the workpiece, and the fixture cylinder drives the jaws to open and close to clamp the workpiece, which is conducive to automatic loading and clamping of the workpiece without the need for worker participation, reducing labor costs and improving work efficiency. However, its automatic loading structure is relatively complex and the manufacturing cost is relatively high. Utility Model Content
