[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A feeding device of a milling machine comprises a feeding rack 1 and a conveyor belt 2 arranged at the upper end of the feeding rack 1 for conveying a workpiece 13, and also comprises a feeding platform 3 located outside the feeding rack 1, and a workpiece pallet 4 docked at the end of the conveyor belt 2 is movably arranged on the upper end of the feeding platform 3, and two sets of parallel limit plates 6 are symmetrically arranged at the position of the feeding rack 1 at the upper end of the conveyor belt 2, and an inclined guide plate 7 is fixedly connected to the side of the limit plate 6 close to the starting end of the conveyor belt 2, and a feeding base 9 for installing the workpiece pallet 4 is slidably arranged on the upper end of the feeding platform 3, and a numerically controlled forward and backward moving mechanism 10 for driving it to move on the upper end of the feeding platform 3 is arranged on the outer side of the feeding base 9, and a numerically controlled rotating mechanism 11 for driving it to rotate relative to the feeding platform 3 is also arranged on the outer side of the feeding base 9, and the upper end of the feeding base 9 is fixedly connected to the bottom of the workpiece pallet 4 through a lifting cylinder 12.

[0022] Among them, an adjusting frame 5 is fixedly connected to the bottom of the feeding rack 1, and a slide groove 501 is horizontally arranged on the upper end of the adjusting frame 5, two groups of sliders 503 are relatively slidably arranged between the slide grooves 501, and the two groups of sliders 503 are respectively fixedly connected to the two groups of limit plates 6 through the brackets 504, and a threaded rod 502 is horizontally rotatably connected in the slide groove 501, and the outer side of the threaded rod 502 is provided with threads in opposite directions, and the threaded rod 502 is threadedly connected to the two groups of sliders 503 through threads in opposite directions, and the outer side of the adjusting frame 5 is also fixedly connected to a motor 8 for driving the threaded rod 502 to rotate at the power end.

[0023] Based on the above structure, in order to ensure that the workpiece 13 can fall from the end of the conveyor belt 2 to the upper end of the workpiece pallet 4 relatively accurately, the staff of the utility model starts the motor 8 in advance through an external switch to drive the threaded rod 502 at the power end to rotate, and the threads on the outer sides of the threaded rod 502 in opposite directions drive the two groups of sliders 503 to slide relative to each other along the slide groove 501, and then adjust the distance between the two groups of limit plates 6 so that the distance between the limit plates 6 can meet the passage of the workpiece 13. In this way, the workpiece 13 is guided by the inclined guide plate 7 in advance with the conveyor belt 2 to approach the two groups of limit plates 6, and then automatically adjusted so that it finally passes through the two groups of limit plates 6 and falls into the relatively center position of the upper end of the workpiece pallet 4, thereby realizing the automatic loading operation of the workpiece 13 and improving the loading efficiency.

[0024] Based on the above-mentioned feeding structure, the workpiece 13 entering the upper end of the workpiece pallet 4 is moved to the milling machine position on the feeding platform 3 by the CNC forward and backward moving mechanism 10 driving the feeding base 9, and the CNC rotating mechanism 11 and the lifting cylinder 12 are used to adjust the angle and height of the workpiece 13 on the workpiece pallet 4 so that it can be relatively accurately docked with the working position of the milling machine, which is very convenient to operate.

[0025] Among them, the contact surfaces of the limit plate 6, the guide plate 7 and the workpiece 13 are all designed with a smooth surface structure, which can reduce the friction when the two are in contact, and facilitate the fast and portable guide correction operation of the workpiece 13.

[0026] In the description of the present invention, it is necessary to understand that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.
