[0024] Example:

[0025] This embodiment provides a simple automatic feeding device for CNC worm milling machines, such as... Figures 1-3 As shown, it includes: The feeding bin 1 has an internal placement groove 101 for securing materials inside. The feeding bin 1 is made of 1mm stainless steel plate bent to ensure that the inner wall is smooth and without protrusions. The worm gear blank moves freely in the feeding bin 1. The gap between the inner wall of the feeding bin 1 and the worm gear blank should not be too large, so as to ensure that it can secure the materials and prevent them from sliding out automatically. The first feeding mechanism is mounted on the mounting frame 6. The output end of the first feeding mechanism is connected to the bottom of the feeding bin 1 and is used to transport the feeding bin 1 along the first motion trajectory direction. The second feeding structure has its output end connected to the mounting frame 6, and is used to transport the mounting frame 6 and the feeding bin 1 in a direction perpendicular to the first motion trajectory.

[0026] In use, the material is placed in the placement slot 101 inside the loading bin 1. The material is stacked upwards in the placement slot 101. During feeding, the first feeding mechanism moves to transport the loading bin 1 along the first motion trajectory direction. The first motion trajectory direction refers to transporting the material from the non-processing area of ​​the machine tool to the processing area. Then, the second feeding structure transports the mounting frame 6 together with the loading bin 1 on it along a direction perpendicular to the first motion trajectory, so that the loading bin 1 reaches the designated position in the processing area.

[0027] It should be noted that the material can only be output after the feeding hopper 1 reaches the designated position. Two motion trajectories are preset, and the two motion trajectories must be perpendicular, that is, in an "L" shape. The material first enters the processing area along the first motion trajectory, and then moves along the direction perpendicular to the first motion trajectory to adjust the position so that the material reaches the final designated position.

[0028] like Figure 3 As shown, the placement trough 101 is a through trough extending from front to back, and it extends along the length of the feeding bin 1. During material output, the material caught in the through trough is pushed out by the relevant structure of the machine tool and falls onto the conveyor belt for transport.

[0029] like Figure 1 As shown, the bottom of the feeding hopper 1 is provided with a first connecting plate 4, which is connected to the output end of the first feeding mechanism. The first connecting plate 4 facilitates the connection between the feeding hopper 1 and the output end of the first feeding mechanism, which is a cylinder.

[0030] The mounting frame 6 is also fixed with a first guide rail 2, and the first connecting plate 4 is slidably connected to the first guide rail 2. By setting the first guide rail 2, it is convenient to guide and position the pushing direction of the first feeding mechanism, thereby improving the stability of the movement of the feeding bin 1. The first guide rail 2 is fixed on the first mounting base 3, and the first mounting base 3 is fixed on the mounting frame 6 to provide support for the installation of the first guide rail 2.

[0031] like Figure 2 As shown, the output end of the second feeding structure is connected to the mounting frame 6 via the second connecting plate 8. The first feeding mechanism uses a cylinder, which, through the second connecting plate 8, facilitates connection to the output end of the second feeding structure, thereby enabling the overall movement of the mounting frame 6 and thus conveying the feed hopper 1 along a different trajectory.

[0032] The second feeding structure is mounted on the second mounting base 10, which is the mounting base for the entire feeding device and is fixed to the frame by bolts. The second mounting base 10 is also provided with a second guide rail 9, and the second connecting plate 8 is slidably connected to the second guide rail 9. By setting the second guide rail 9, it is convenient to guide and position the pushing direction of the second feeding mechanism, thereby improving the stability of the movement of the feeding bin 1.

[0033] Therefore, the automatic feeding device of this invention can replace the vibrating feeder in the prior art, eliminating the risk of worm gears colliding with each other, reducing the defect rate caused by blank damage in worm gear production, and improving the stability of worm gear production. At the same time, it reduces feeding transfer points, greatly alleviating feeding jamming, making automated production smoother, improving production efficiency in terms of production cycle time, and creating more processing profits. Furthermore, the free-fall vertical feeding bin 1 can distinguish and position the feeders, replacing the disadvantage of the vibrating feeder not being able to separate feeders, ensuring the stability of automated production. In addition, the device of this invention can replace the complex robotic automatic loading and unloading, with low cost, achieving the effect of low cost and high efficiency.

[0034] Finally, it should be noted that the above specific embodiments are only used to describe the purpose, technical solution, and beneficial effects of this utility model in detail. It should be understood that the above description is only a specific implementation of this utility model and is not intended to limit the protection scope of this utility model. Although this utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions or improvements can be made to some or all of the technical features. These modifications, equivalent substitutions, and improvements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
