A cutting milling cutter 14 driven by the motor 20 is provided inside the cutting groove 13.

[0021] The feeding device includes a cylinder 5 and a push plate 6. The cylinder 5 is fixedly installed on the upper table of the frame 1. The outer wall of the left end of the guide trough 4 is provided with a mounting groove facing the cutting groove 13, and a push plate 6 is slidably provided in the mounting groove. The telescopic rod of the cylinder 5 is fixedly connected to the push plate 6.

[0022] The supporting device includes a vertical shaft 24 and an extrusion sleeve 9. Two rows of vertical shafts 24 are fixed on the top of the first mounting plate 22, which are respectively located in the two limiting conveyor belts 8, and the outer wall of the vertical shaft 24 is rotatably sleeved with an extrusion sleeve 9. The outer wall of the extrusion sleeve 9 is rollingly connected to the inner wall of the limiting conveyor belt 8 on one side close to the cutting milling cutter 14.

[0023] The adjusting device includes a slide groove 15, a vertical plate 16, and a guide rod 17. A pair of slide grooves 15 are symmetrically opened on the upper surface of the frame 1, and a pair of adjustment plates 21 driven by the driving device are respectively slidably arranged in the pair of slide grooves 15. A pair of vertical plates 16 are fixed to the bottom of the upper surface of the frame 1, and a pair of guide rods 17 are fixed between the pair of vertical plates 16. The outer walls of the guide rods 17 are slidably connected to the pair of adjustment plates 21.

The adjusting motor 19 is fixedly installed on the side of the vertical plate 16, and the output shaft of the adjusting motor 19 is fixedly connected to the forward and reverse bidirectional screw 18.

[0027] Working principle: the parts in the material storage bin 2 pass through the conveying trough 3 and enter the guide trough 4 and are intermittently pushed between the two limiting conveyor belts 8 by the cylinder 5 and the push plate 6, so that the bottom of the part fits into the upper table of the frame 1 and the tail nail at the bottom of the part falls completely into the cutting groove 13. After the push plate 6 pushes a part between the two limiting conveyor belts 8, the driving motor 23 synchronously drives the two limiting conveyor belts 8 to drive the partition 11 to rotate and make the part clamped by the two pairs of partitions 11 on the two limiting conveyor belts 8 and drive the part to move right and make the tail nail at the bottom of the part be cut and eliminated by the cutting milling cutter 14. The partition 11 continues to drive the part to move right until it enters the material storage bin 2. The forward and reverse bidirectional screw 18 is driven to rotate by the adjusting motor 19 so that the two first mounting plates 22 are synchronously approached, thereby increasing the clamping force of the partition 11 on the part and adapting to parts of different diameters. The limiting conveyor belt 8 and the partition 11 are tightly supported after contact with the part by the extrusion sleeve 9.

[0028] When the device pushes the part to move right and the tail nail is cut off by the cutting milling cutter 14, the part is clamped and limited by the partition 11, so as to keep the part stable and prevent the part from tilting. It can not only ensure that the tail nail of each part is cut, but also the tail nail removal rate is higher, and the tail nail cutting is more comprehensive and thorough, and the tail nail removal effect is better. It can make the two limiting conveyor belts 8 approach or move away synchronously, and can not only adjust the clamping force of the part to make the clamping more stable, but also can adapt to parts of different diameters and have a wider range of adaptability.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
