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.

Please refer to Figures 1-2. The utility model provides a positioning and cutting device for a machining center, including a workbench 1. The inner wall of the workbench 1 is slidably connected to a clamping block 2, and the workpiece to be processed is fixed by the clamping block 2. The upper outer wall of the workbench 1 is slidably connected to a support frame 11. The support frame 11 is driven by electricity to move in the horizontal direction along the electric guide rail of the upper outer wall of the workbench 1 to adjust the cutting direction. The inner wall of the support frame 11 is slidably connected to a telescopic rod 12. The end of the telescopic rod 12 is provided with a lifting device to control the lifting of the telescopic rod 12. The end of the telescopic rod 12 is fixedly connected to a connecting frame 13, and the inner wall of the connecting frame 13 is connected to the inner wall of the telescopic rod 12. The wall is provided with a protective shell to prevent people from being cut by the blade. The outer wall of the connecting frame 13 is welded with a motor 15. The output shaft of the motor 15 is fixedly connected with a rotating shaft 16. The outer wall of the rotating shaft 16 is detachably connected with a cutting blade 18. The end of the rotating shaft 16 is provided with a rectangular protrusion structure that can clamp the inner wall of the cutting blade 18. After driving the motor 15, the cutting blade 18 is driven to rotate together to cut the clamped workpiece. The inner wall of the workbench 1 is fixedly connected with a guide rod 3. The outer wall of the guide rod 3 is slidably connected to the inner wall of the clamp block 2. The outer wall of the bottom end of the clamp block 2 is hinged with a bracket 4 on the inner side. The end of the bracket 4 is hinged with an adjusting rod 5. The adjusting rod 5 A rectangular block 6 is passed through the outer wall and slidably connected. A handle is provided at the end of the adjusting rod 5. Dragging or pushing the handle will cause the adjusting rod 5 to slide along the inner wall of the rectangular block 6. While sliding, the angle of the bracket 4 is offset, thereby dragging the two groups of clamping blocks 2 to move closer to or separate from each other along the guide rod 3, thereby controlling the clamping blocks 2 to clamp the workpiece. The outer wall of the inner end of the rectangular block 6 is fixedly connected to the side wall of the workbench 1, and the inner wall of the rectangular block 6 is elastically connected to a buckle assembly through a reset spring a7. The buckle assembly includes a limit block 8, one end of the reset spring a7 is fixedly connected to the top of the limit block 8, and the other end of the reset spring a7 is fixedly connected to the rectangular block 6 is fixedly connected, the limit block 8 can squeeze the reset spring a7 to move upward, and at the same time, the elastic force generated by the deformation of the reset spring a7 gives the limit block 8 a thrust in the opposite direction to reset it, and the top of the limit block 8 is fixedly connected with a pull rod a10, the outer wall of the pull rod a10 penetrates and is slidably connected to the inner wall of the rectangular block 6, and pulling the pull rod a10 outward can drive the limit block 8 to move upward, and a plurality of groups of limit grooves 9 are provided on the outer wall of the adjusting rod 5, and the outer wall of the limit block 8 is clamped with the inner wall of the limit groove 9. After pulling the pull rod a10 outward until the limit block 8 and the limit groove 9 are released from the clamping, the handle can be turned to drive the adjusting rod 5 to move.

Please refer to Figures 1 and 3. A pull rod b14 is passed through the inner wall of the connecting frame 13 and is slidably connected. The end of the pull rod b14 is plugged into the central circular groove of the rotating shaft 16. The outer walls of the rotating shaft 16 and the pull rod b14 are both provided with a cylindrical baffle 17 to ensure that the cutting blade 18 is in the middle of the protective shell to prevent the cutting blade 18 from changing its position during rotation and causing the cutting position to shift. When the pull rod b14 is separated from the rotating shaft 16, the cutting blade 18 can be removed. A clamping block 19 is fixedly connected to the inner wall of the connecting frame 13 through a reset spring b20. One end of the reset spring b20 is fixedly connected to the inner wall of the connecting frame 13, and the other end of the reset spring b20 contacts the clamping block 19. Under normal circumstances, the clamping block 19 clamps the connecting frame 13 The inner wall prevents the cutting blade 18 from rotating at high speed and compressing the cylindrical baffle 17 so that the pull rod b14 moves to the right and is pulled out of the circular groove of the rotating shaft 16, causing the blade to fall. The pull rod b14 is not manually rotated until the block 19 is aligned with the inner wall groove of the connecting frame 13. The block 19 can be moved outward by pulling the pull rod b14 outward. The outer wall of the pull rod b14 is fixedly connected to the inner wall of the block 19. At this time, the reset spring b20 generates an outward thrust to the block 19 due to the elastic force generated by the deformation, causing it to reset. When the pull rod b14 is pulled out of the circular groove of the rotating shaft 16, the cutting blade 18 is replaced. After the replacement is completed, let go and the end of the pull rod b14 will be pushed back into the rotating shaft 16 by the reset spring b20.

Working principle: Place the workpiece to be cut on the workbench 1, pull the pull rod a10 upwards, pull the adjustment rod 5 outwards, so that the angle of the bracket 4 is offset, and drag the two sets of clamping blocks 2 along the guide rod 3 to move closer to each other to fix the workpiece. After fixing, release the pull rod a10, and the reset spring a7 pushes the limit block 8 into the limit groove 9 to fix the clamping device, and then the support frame 11 and the telescopic rod 12 are electrically operated to calibrate the cutting position, and then the driving motor 15 drives the cutting blade 18 to rotate to cut the workpiece. When the cutting blade 18 needs to be replaced due to wear and tear during long-term use, rotate the pull rod b14 until the block 19 is aligned with the inner wall groove of the connecting frame 13 and then pull it outward to release the plugging connection between the end of the pull rod b14 and the central circular groove of the rotating shaft 16. At this time, the cutting blade 18 can be replaced. After the replacement, install the new cutting blade 18, release the pull rod b14, and the reset spring b20 will push its end back into the circular groove of the rotating shaft 16. Then rotate the pull rod b14 to make the block 19 re-engage the inner wall of the connecting frame 13.

Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
