Technical Field

[0001] This application relates to the field of cutting machine technology, and in particular to an adjustable cutting machine. Background Technology

[0002] During the machining process, it is inevitable to use a cutting machine to cut the edges and corners of the workpiece to make them more rounded. However, when using a cutting machine to cut the edges and corners, the blades on the cutting machine, driven by the motor, can only move up and down, not rotate horizontally. This requires the worker to manually rotate the workpiece horizontally to make contact with the rotating blades and cut the edges and corners. This can easily lead to safety accidents, as workers' hands are very likely to be cut by the blades, and the curvature of the four edges and corners of the workpiece will also be inconsistent. Utility Model Content

[0014] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0015] Example 1:

[0016] An adjustable cutting machine, as described above Figure 1-3The system includes a base 1, a column 3, and a movable rod 4. A limiting plate 2 is fixedly connected to the middle of the top of the base 1. The bottom end of the workpiece is placed in the limiting plate 2, and the four sides of the bottom end of the workpiece are respectively attached to the four inner side walls of the limiting plate 2, thus limiting the workpiece. The column 3 is fixedly connected to the edge of the top of the base 1. One end of the movable rod 4 movably passes through the column 3. A limiting component 5 for limiting the movable rod 4 is provided on the inner top of the column 3. The limiting component 5 consists of two sliding holes 51 and two sliders 52. The two sliding holes 51 are respectively opened on the two inner side walls of the column 3. The two sliders 52 are respectively welded to both sides of the movable rod 4. The two sliders 52 slide inside the two sliding holes 51, and the two sides of the two sliders 52 are respectively connected to the two sliding holes 51. The two inner sidewalls of the column 3 are fitted together, which limits the movement of the rod 4, allowing it to move only vertically. A servo electric cylinder 6 is installed on the inner bottom wall of the column 3. The telescopic end of the servo electric cylinder 6 is welded to one end of the bottom of the rod 4. The servo electric cylinder 6 is electrically connected to an external power supply via an external switch. The preferred model of the servo electric cylinder 6 is MPED-180. After the servo electric cylinder 6 is started to work by the external switch, its telescopic end can drive the rod 4 to move up and down during the telescopic process. A rotating shaft 71 is rotatably inserted through the other end of the top of the rod 4. A connecting plate 72 is welded to the bottom end of the rotating shaft 71. A ring 73 is fixedly fitted on the outer surface of the middle part of the rotating shaft 71. The top surface of the ring 73 is fitted with the bottom surface of the rod 4. The top of the rotating shaft 71 is... A gear ring 74 is fixedly sleeved on the outer surface of the movable rod 4. The bottom end face of the gear ring 74 is in contact with the top end face of the movable rod 4. A driving component 8 for driving the rotation of the gear ring 74 is installed in the middle of the top end of the movable rod 4. The driving component 8 consists of a reversible motor 81 and a gear ring 82. A circular hole is opened in the middle of the top end of the movable rod 4. The reversible motor 81 is fixedly inserted through the circular hole. The reversible motor 81 is electrically connected to an external power source through an external switch. The reversible motor 81 is preferably of type TCH(V)22-100-140CB. The gear ring 82 is fixedly sleeved on the end of the power shaft of the reversible motor 81. The gear ring 82 meshes with the gear ring 74. A cutting component 9 is installed on one side of the connecting plate 72. After the reversible motor 81 is started by the external switch, its power... The shaft drives gear ring 82 to rotate gear ring 74. Gear ring 74 rotates the connecting plate 72 via rotating shaft 71, thus allowing horizontal angle adjustment of the cutting assembly 9. The cutting assembly 9 consists of a motor 91 and a cutting blade 94. The motor 91 is fixedly mounted on one side of the connecting plate 72 and is electrically connected to an external power source via an external switch. The motor 91 is preferably a YE2132M-4 type. The drive shaft of the motor 91 rotates through the connecting plate 72. A baffle 92 is welded to the end of the drive shaft of the motor 91. A hexagonal block 93 is welded to one side of the baffle 92. The cutting blade 94 is fitted onto the outer surface of the hexagonal block 93, with one side of the cutting blade 94 fitting against one side of the baffle 92. A threaded post 95 is welded to one side of the hexagonal block 93.Nut 96 is threaded onto the outer surface of threaded post 95, with one side of nut 96 engaging with the other side of cutting disc 94. This allows cutting disc 94 to be fixedly mounted on the drive shaft of motor 91. The drive shaft of motor 91 then rotates cutting disc 94, enabling the cutting of the four corners of the workpiece.

[0017] The implementation principle of an adjustable cutting machine according to an embodiment of this application is as follows: First, the bottom end of the workpiece is inserted into the limiting plate 2. Then, the servo electric cylinder 6 and the starter motor 91 are started using an external switch. The power shaft of the motor 91 drives the cutting blade 94 to rotate. The extension end of the servo electric cylinder 6 drives the movable rod 4 to move downward. The movable rod 4 moves downward through the rotating shaft 71 and the gear ring 74, so that the rotating cutting blade 94 can contact one corner of the workpiece. The forward and reverse motor 81 is controlled by the external switch. The power shaft of the forward and reverse motor 81 drives the gear ring 82 to rotate the gear ring 74. The gear ring 74 drives the connecting plate 72 to rotate through the rotating shaft 71. Thus, the horizontal angle of the motor 91 and the cutting blade 94 can be adjusted, thereby sequentially cutting the four corners of the top surface of the workpiece with arc. During this process, if the top surface of the workpiece... After the four corners are cut into arc shape, the workpiece is flipped vertically to swap the positions of the top and bottom surfaces. One end of the workpiece with the cut corner is then inserted into the limiting plate 2. An external switch is then used to control the forward / reverse motor 81 to rotate the gear ring 82 in the opposite direction. The gear ring 82 rotates the gear ring 74, which in turn rotates the connecting plate 72 via the rotating shaft 71. This allows for horizontal angle adjustment of the motor 91 and the cutting blade 94 in opposite directions, sequentially cutting the four corners of the other end of the workpiece into arc shape. This process also prevents the motor 91 from winding. It is important to note that after the cutting blade 94 moves downward, the cutting depth is greater than half the workpiece height. This ensures that after the workpiece is flipped and cut twice, all four corners are completely arc-shaped, and the cutting blade 94 does not touch the limiting plate 2.
