[0038] The stretching assembly 6 is used to drive the multiple pulleys 5 to move and change the spacing between them to match the inner diameter of the cylindrical workpiece, and is arranged on one side of the baffle 3;

[0039] The limiting component 7 is used to change the horizontal position of the plurality of pulleys 5 and limit their positions, matches the wall thickness of the cylindrical workpiece, and is arranged on the baffle 3.

[0040] The extension assembly 6 includes a mounting seat 61 disposed on one side of the baffle plate 3 .

[0041] A rotating member 8 is arranged in the mounting seat 61, which is used to drive the multiple pulleys 5 to move synchronously and change the spacing between the multiple pulleys 5; the rotating member 8 includes a through shaft 81 rotatably arranged on the mounting seat 61, a rotating disk 82 is arranged on the through shaft 81, a plurality of sliders 83 are slidably arranged on the mounting seat 61, and a connecting shaft 84 is arranged on each of the multiple sliders 83. The multiple pulleys 5 are rotatably arranged on the multiple connecting shafts 84, respectively, and baffles 85 are arranged on each of the multiple sliders 83. A plurality of connecting bars 86 are rotatably arranged on the rotating disk 82, and the plurality of connecting bars 86 are rotatably connected to the plurality of baffles 85 respectively; The through shaft 81 drives the rotating disk 82 to rotate, and the multiple connecting strips 86 are deflected, driving the multiple baffles 85, sliders 83, connecting shafts 84, and pulleys 5 to move, thereby changing the spacing between the multiple pulleys 5 to match the inner diameter size of the cylindrical workpiece. The cylindrical workpiece is mounted on the outside of the multiple pulleys 5, and the inner wall of the workpiece is in contact with the multiple pulleys 5. The cylindrical workpiece can rotate around the axis of the through shaft 81; the pulley 5 can be made of anti-scratch materials such as ABS plastic, which can effectively support and limit the inner wall of the cylindrical workpiece while reducing the friction between each other. It is also corrosion-resistant and has a longer service life.

[0042] A limit member 9 is provided on the mounting seat 61 for controlling the rotating member 8 to limit the position of the multiple pulleys 5 with changed spacing; the limit member 9 includes a worm wheel 91 arranged on the through shaft 81, a limit rod 92 is rotatably provided on the mounting seat 61, a first rotating piece 93 is provided at one end of the limit rod 92, a worm 94 is provided on the limit rod 92, and the worm 94 is meshed with the worm wheel 91; the first rotating piece 93 is rotated to drive the limit rod 92 and the worm 94 to rotate, and the worm wheel 91 and the through shaft 81 are driven to rotate through the meshing; the self-locking effect between the worm wheel 91 and the worm 94 completes the position limitation of the through shaft 81 and the rotating disk 82, avoids the deflection of the rotating disk 82 caused by the vibration generated by the chamfering process, and ensures the position limitation of the multiple pulleys 5; a cross groove structure can be provided on the first rotating piece 93, through this design, a screwdriver or other tool can be used to assist in rotating the first rotating piece 93, so that the operation of adjusting the position of the multiple pulleys 5 is more labor-saving and convenient.

[0043] The limiting assembly 7 includes a connecting plate 71 arranged above the baffle plate 3 .

[0044] Folding parts 10 are provided on both sides of the connecting plate 71, which are used to connect with the mounting seat 61 and rotate and store the mounting seat 61; the folding part 10 includes a slide plate 101 arranged on the connecting plate 71, the slide plate 101 is slidably connected with the baffle plate 3, a connecting bar 102 is provided on the slide plate 101, and a rotating bar 103 is provided on the mounting seat 61, and the rotating bar 103 is rotatably connected with the connecting bar 102; the mounting seat 61 can be rotated on the connecting bar 102 through the rotating bar 103, and the mounting seat 61 can be rotated when not in use to be folded and stored in a box to save space.

[0045] The top surface structural material of the mounting seat 61 is a magnetic material; after the mounting seat 61 is rotated, it can be adsorbed on the controller 1, so that the overall structure after folding and storage is more stable, and it can be avoided that the parts move back and forth and become loose when subjected to vibration; when it is necessary to chamfer certain immovable workpieces to prevent burrs from hurting people, the mounting seat 61 can be folded and stored to avoid the structure blocking the workpiece and ensure the normal use of the cutting head 4.

[0046] A displacement member 11 is provided on the baffle plate 3, which is used to drive the mounting seat 61 to move in the horizontal direction and limit its position; the displacement member 11 includes a fixed plate 111 arranged on the baffle plate 3, and a screw 112 is rotatably provided on the fixed plate 111, the connecting plate 71 is threadedly connected to the screw 112, and a second rotating piece 113 is provided at one end of the screw 112; rotating the second rotating piece 113 drives the screw 112 to rotate, and drives the connecting plate 71, the slide plate 101, the connecting bar 102, the rotating bar 103, and the mounting seat 61 to move through the threaded connection, thereby changing the distance between the multiple pulleys 5 and the cutting rotary head 4, and the distance between the cutting rotary head 4 and the leftmost pulley 5, which matches the wall thickness size of the cylindrical workpiece; similarly to the first rotating piece 93, a cross groove structure can also be provided on the second rotating piece 113 to facilitate the auxiliary rotation of the second rotating piece 113.

[0047] Two vertical plates 12 are arranged on the baffle plate 3, and limit strips 13 are arranged on the two vertical plates 12. The bottom surfaces of the two limit strips 13 are in the same horizontal plane with the circular end surface of the mounting seat 61. Since the mounting seat 61 can be rotated by the rotating strip 103, the mounting seat 61 needs to be limited when the chamfering process is actually performed. The limit strip 13 contacts and pushes the mounting seat 61 to prevent the mounting seat 61 from being rotated by the reaction force. At the same time, in order to allow the mounting seat 61 to be rotatable and stored, when the mounting seat 61 is displaced to the limit position in the horizontal direction and is farthest from the cutting head 4, the mounting seat 61 can be separated from the limit strip 13, thereby being rotatably stored. In order to facilitate operation and avoid the need to adjust the mounting seat 61 to the limit position every time it is folded and stored, the vertical plate 12 can be slidably set on the baffle plate 3. The sliding vertical plate 12 makes it actively separate from the mounting seat 61, releases the rotation limit of the mounting seat 61, thereby completing the rotation storage of the mounting seat 61, which is convenient for operation.

[0048] When in use, the first rotating piece 93 is rotated to drive the limit rod 92 and the worm 94 to rotate, and the worm wheel 91 and the through shaft 81 are driven to rotate through meshing, and the through shaft 81 drives the rotating disk 82 to rotate, and the multiple connecting bars 86 are deflected, driving the multiple baffles 85, the slider 83, the connecting shaft 84, and the pulley 5 to move, thereby changing the spacing between the multiple pulleys 5; the second rotating piece 113 is rotated to drive the screw 112 to rotate, and the connecting plate 71, the slide plate 101, the connecting bar 102, the rotating bar 103, and the mounting seat 61 are driven to move through the threaded connection, thereby changing the distance between the multiple pulleys 5 and the cutting rotary head 4.

[0049] When it is necessary to chamfer the outer wall of the cylindrical workpiece, adjust the spacing between the multiple pulleys 5 to match the inner diameter of the workpiece, adjust the distance between the leftmost pulley 5 and the cutting head 4 to match the wall thickness of the cylindrical workpiece, and the cylindrical workpiece is mounted on the outside of the multiple pulleys 5. The inner wall of the workpiece contacts the multiple pulleys 5, and the cylindrical workpiece rotates around the axis of the through-shaft 81. During the rotation of the workpiece, the cutting head 4 chamfers the outer wall of the workpiece.

[0050] When it is necessary to chamfer the inner wall of the cylindrical workpiece, adjust the distance between the leftmost pulley 5 and the cutting head 4, the cylindrical workpiece is inserted between the leftmost pulley 5 and the cutting head 4, the inner wall of the workpiece contacts the pulley 5 and the cutting head 4, the workpiece rotates around the perpendicular midline of the pulley 5 and the cutting head 4, and during the rotation of the workpiece, the cutting head 4 chamfers the inner wall of the workpiece.

[0051] It should be noted that the distance between the leftmost pulley 5 and the cutting head 4 that need to be set when chamfering the inner and outer walls may not be equal. The inner and outer wall chamfering may require adjustment of the calibration distance. To ensure the speed of the chamfering operation, after the outer (inner) wall chamfering of a batch of workpieces is completed, the inner (outer) wall chamfering is performed uniformly. In this way, the distance only needs to be adjusted and calibrated once.

[0054] A boss 14 is provided on the mounting seat 61, and a limit rod 92 is rotatably connected to the boss 14, and an indicator needle 15 is provided on the first rotating plate 93; the boss 14 is provided with scale lines and other markings, and the indicator needle 15 cooperates with the scale lines and other markings, so that the rotation angle of the first rotating plate 93 corresponds to the spacing value of the plurality of pulleys 5, thereby making the adjustment change of the distance more accurate and clear.
