[0008] An edge grinding ring body is rotatably connected to the support frame, the axis of the edge grinding ring body is parallel to the axis of the workpiece, and a grinding material is provided on the inner wall of the edge grinding ring body. The workpiece can contact the inner wall of the edge grinding ring body during the process of adjusting its position along the length direction;

[0009] The edge grinding motor is used to drive the edge grinding ring to rotate.

[0010] In this technical solution, the workpiece is clamped by the clamping unit and then cut by the cutting unit. After cutting, the position of the workpiece is adjusted along the length direction of the workpiece so that there is an axial distance between the workpiece and the edging ring body. Then the position of the support frame is adjusted so that the edging ring body and the workpiece are coaxial. At this time, the edging motor is started to drive the edging ring body to rotate, and then the cut end face of the workpiece is brought close to the edging ring body along the length direction. The edge of the cut end face of the workpiece contacts the grinding material on the inner wall of the edging ring body. At this time, the grinding material follows the edging ring body to make a circular motion to grind the edge of the cut end face of the workpiece.

[0020] The beneficial effects of the utility model are:

[0021] 1. By setting up the cooperation of the base, cutting unit, clamping unit, support frame, edge grinding ring and edge grinding motor, after the clamping unit fixes the workpiece on the base, the cutting unit cuts the workpiece. After the cutting is completed, the support frame, edge grinding ring and edge grinding motor cooperate to grind the edge of the cut end face of the workpiece to remove burrs on the edge of the cut end face of the workpiece, so as to prevent workers from being scratched by burrs during the process of handling the workpiece.

[0022] 2. By gradually reducing the inner wall diameter of the edging ring body as it moves away from the workpiece, for workpieces of different diameters, it is only necessary to adjust the distance between the workpiece and the edging ring body so that the cut end face of the workpiece can contact the grinding material on the inner wall of the edging ring body, thereby completing the grinding of the edge of the cut end face of the workpiece, thereby improving the applicability of the cutting device.

[0041] In one embodiment of the present invention, the cutting unit 2 includes: a lifting frame 201, a circular blade 202, a cutting motor 203, a cutting cylinder 8,

[0042] See also Figure 4 The lifting frame 201 is movably mounted on the fixed frame 7. In this embodiment, a guide groove is provided on the fixed frame 7 in the vertical direction. Both ends of the lifting frame 201 are slidably mounted in the guide groove. The guide groove limits the lifting frame 201 to vertical movement only.

[0043] The circular blade 202 is rotatably mounted on the lifting frame 201. The circular blade 202 can be a commercially available product. The circular blade 202 contacts the workpiece 100 when rotating at high speed and can cut the workpiece 100.

[0044] The cutting motor 203 is mounted on the lifting frame 201 and is used to drive the circular blade 202 to rotate;

[0045] The fixed end of the cutting cylinder 8 is arranged on the base 1 or the fixed frame 7, and the movable end of the cutting cylinder 8 is connected to the lifting frame 201 for driving the lifting frame 201 to rise and fall relative to the base 1 and the fixed frame 7.

[0046] See also Figure 5 The support frame 4 is movably arranged on one side of the base 1, and the support frame 4 can be close to and away from the base 1; the support frame 4 is arranged below the fixed frame 7, and the fixed frame 7 is provided with an edging cylinder 9, which is used to drive the support frame 4 to rise and fall relative to the base 1;

[0047] The inner diameter of the edging ring body 5 is larger than the outer diameter of the workpiece 100, so that the end of the workpiece 100 can extend into the edging ring body 5. The edging ring body 5 is rotatably connected to the support frame 4. The axis of the edging ring body 5 is parallel to the axis of the workpiece 100. A grinding material is provided on the inner wall of the edging ring body 5. The grinding material can grind the surface of the workpiece 100.

[0048] Figure 1 The figure shows the state where the clamping unit 3 clamps the workpiece 100. At this time, the support frame 4 and the edge grinding ring 5 are away from the workpiece 100. The cutting motor 203 starts to drive the circular blade 202 to rotate at high speed, waiting for the cutting cylinder 8 to drive the lifting frame 201 to descend and cut the workpiece 100.

[0049] Figure 2 What is shown is the state of the workpiece 100 after being cut. A section of the workpiece 100 has been removed after cutting, and the other section of the workpiece 100 is still clamped by the clamping unit 3, and the position of this section of the workpiece 100 is adjusted in the length direction so that the cut end face of the workpiece 100 does not interfere with the support frame 4 and the edge grinding ring 5. At this time, the support frame 4 and the edge grinding ring 5 are close to the base 1 and the edge grinding ring 5 is coaxial with the workpiece 100. In this way, the workpiece 100 is subsequently moved toward the direction close to the edge grinding ring 5, and the edge grinding ring 5 is driven to rotate by the cutting motor 203, so that the cut end face of the workpiece 100 can be polished and ground when it contacts the grinding material on the inner wall of the edge grinding ring 5, thereby removing burrs on the edge of the cut end face of the workpiece 100.

[0050] In one embodiment of the present invention, please refer to Figure 5 , the inner wall diameter of the edging ring body 5 gradually decreases in the direction away from the workpiece 100; when in use, when the diameter of the workpiece 100 is large, the end of the workpiece 100 only needs to extend into the inner side of the edging ring body 5 a shorter distance to contact the grinding material; when the diameter of the workpiece 100 is small, the end of the workpiece 100 needs to extend into the inner side of the edging ring body 5 a longer distance to contact the grinding material. In this way, for workpieces 100 with different diameters, it is only necessary to adjust the distance between the workpiece 100 and the edging ring body 5 to make the cut end face of the workpiece 100 contact the grinding material on the inner wall of the edging ring body 5, thereby completing the grinding of the edge of the cut end face of the workpiece 100.

[0051] The embodiments of the present invention are described above in conjunction with the accompanying drawings.
