DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-5 , the utility model provides an embodiment: a feeding structure of a CNC turning and milling machine, including a base 1, a positioning seat 4 is fixedly connected to the top of the base 1, a first motor 5 is fixedly connected to the left end of the positioning seat 4, a threaded rod 20 is fixedly connected to the driving end of the first motor 5, a feeding box 7 is fixedly connected to the top of the positioning seat 4, a driving shaft 11 is rotatably connected to the inner wall of the feeding box 7, a rotating disk 12 is fixedly connected to the outer wall of the driving shaft 11, a feeding trough 16 is opened on the upper and lower sides of the rotating disk 12, a storage box 9 is fixedly connected to the top of the feeding box 7, an inclined plate 10 is fixedly connected to the inner wall of the storage box 9, an opening is opened on the upper and lower sides of the feeding box 7, the size of the openings on the upper and lower sides of the feeding box 7 is the same as the size of the feeding troughs 16 on the upper and lower sides, the discharge port at the bottom of the storage box 9 is the same as the size of the upper opening of the feeding box 7, a second motor 8 is fixedly connected to the left end of the feeding box 7, and the left end of the driving shaft 11 is fixedly connected to the driving end of the second motor 8. The outer wall of the threaded rod 20 is threadedly connected with a push plate 2, the inner wall of the positioning seat 4 is provided with a push groove 6, the outer wall of the push plate 2 is slidably connected to the inner wall of the push groove 6, the bottom opening of the unloading box 7 is located directly above the push groove 6, and the right end of the base 1 is fixedly connected to the frame 3.

[0025] Specifically, when the frame 3 needs to replace the material rods, the second motor 8 on the left side of the discharge box 7 is started, and the second motor 8 drives the driving shaft 11 to rotate 180 degrees, thereby driving the rotating disk 12 to rotate 180 degrees, so that the discharge chute 16 on the upper side of the rotating disk 12 rotates to the pushing chute 6 below, and then the material rods on the discharge chute 16 fall onto the pushing chute 6 on the inner wall of the positioning seat 4, and the discharge chute 16 on the lower side rotates to the top. At this time, the material rods in the storage box 9 will roll into the discharge chute 16 along the inclined plate 10 to complete the filling, waiting for the next rotation of the rotating disk 12, and the discharge chute 16 is in line with the size of the material rods and can only load one material rod at a time. When the material rod falls into the pushing chute 6 on the positioning seat 4, the first motor 5 is started, and the first motor 5 drives the threaded rod 20 to rotate, so that the push plate 2 pushes the material rod to the right along the pushing chute 6 into the frame 3, realizing automatic loading of the material rods, saving time and improving work efficiency.

[0026] The opposite end of the material discharge chute 16 is fixedly connected to a first electric push rod 18, and the driving end of the first electric push rod 18 is fixedly connected to a storage plate 13. The right end of the material discharge chute 16 is fixedly connected to a second electric push rod 17, and the driving end of the second electric push rod 17 is fixedly connected to a moving plate 15. The inner walls of the upper and lower storage plates 13 are slidably connected to sliding plates 14. The front and rear sides of the left ends of the inner walls of the upper and lower storage plates 13 are fixedly connected to springs 19, and the left end of the sliding plate 14 is fixedly connected to the right end of the spring 19.

[0027] Specifically, when using material rods of different sizes, it is only necessary to start the second electric push rods 17 on the upper and lower material discharge troughs 16 first, and the second electric push rods 17 drive the movable plate 15 to move to the left, thereby squeezing the sliding plate 14, and the sliding plate 14 compresses the spring 19 and moves toward the left side of the inner wall of the receiving plate 13, and then start the first electric push rod 18, the first electric push rod 18 drives the receiving plate 13 to move upward, and the receiving plate 13 drives the sliding plate 14 to move upward, so that the material discharge trough 16 becomes smaller, and the first electric push rod 18 and the second electric push rod 17 are both controlled by the controller at the top of the base 1 and electrically connected to it. When the material discharge trough 16 is to be enlarged, it is only necessary to start the second electric push rod 17 to move the movable plate 15 to the right, and the sliding plate 14 rebounds under the action of the spring 19, and then start the first electric push rod 18 to move the receiving plate 13 downward, and at the same time drive the sliding plate 14 downward, so that the material discharge trough 16 becomes larger, so that it can adapt to material rods of different sizes, thereby improving the flexibility and applicability of the equipment.

[0028] Working principle: When the rack 3 needs to replace the material rod, the second motor 8 is started, and the second motor 8 drives the driving shaft 11 to rotate 180 degrees, thereby driving the rotating disk 12 to rotate 180 degrees, so that the material discharge chute 16 on the upper side of the rotating disk 12 rotates to the bottom, and then the material rod on the material discharge chute 16 falls onto the pushing chute 6, and the material discharge chute 16 on the lower side rotates to the top. At this time, the material rod in the storage box 9 will roll into the material discharge chute 16 along the inclined plate 10, waiting for the next rotation of the rotating disk 12. When the material rod falls into the pushing chute 6, the first motor 5 is started, and the first motor 5 drives the threaded rod 20 to rotate, so that the push plate 2 pushes the material rod to the right along the pushing chute 6. The material rods are automatically loaded into the frame 3, which saves time and improves work efficiency. When material rods of different sizes are needed, it is only necessary to start the second electric push rods 17 on the upper and lower material discharge troughs 16. The second electric push rods 17 drive the movable plate 15 to move leftward, squeeze the sliding plate 14, and the sliding plate 14 compresses the spring 19 to move toward the left side of the inner wall of the storage plate 13. Then the first electric push rod 18 is started, and the first electric push rod 18 drives the storage plate 13 to move upward, and the storage plate 13 drives the sliding plate 14 to move upward, thereby changing the size of the material discharge trough 16 to adapt to material rods of different sizes, thereby improving the flexibility and application range of the equipment.
