Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0025] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0027] Reference Figure 1-7 A high-precision CNC metal circular saw machine comprises a bracket 1, a top frame 6 is welded on the top of the bracket 1, a turntable 3 is provided in the middle of the top of the bracket 1, a feeding roller 21 is movably connected inside the turntable 3, a driving shaft 13 is installed on the front and back sides of the turntable 3 near the feeding roller 21, the end of the driving shaft 13 is transmission-connected with a rotating shaft wheel 12, the outside of the rotating shaft wheel 12 and the feeding roller 21 are provided with teeth 23, the rotating shaft wheel 12 and the feeding roller 21 are adapted to each other and mesh with each other, the top and bottom of the feeding roller 21 are provided with grooves, clamping cylinder groups 26 are installed on both sides of the top and bottom grooves of the feeding roller 21, the ends of the clamping cylinder groups 26 are electrically connected to the cylinder columns 27, the ends of the cylinder columns 27 are clamped with clips 24, a pressure sensor 28 is installed inside the clips 24, and object sensors 25 are installed in the grooves at the top and bottom of the feeding roller 21.

[0028] The pressure sensor 28 here is a pressed sheet pressure sensor purchased directly from the market, and the object sensor 25 is a microwave sensor purchased directly from the market.

[0029] A push controller 9 is installed on one side of the bottom of the bracket 1 , one end of the push controller 9 is electrically connected to a push cylinder group 10 , and a push piece 11 is clamped at the end of the push cylinder group 10 .

[0030] A loading box 4 is placed at the bottom of the bracket 1 near the bottom of the transfer port 3, and a receiving box 5 is placed on one side of the loading box 4. A placing plate 30 is provided in the loading box 4, and a workpiece 29 is placed on the top of the placing plate 30. The workpiece 29 is stacked. The loading box 4 is used to place the workpiece 29, and the receiving box 5 is used to recycle the processed workpieces.

[0031] The structures in the grooves at the top and bottom of the feeding roller 21 are the same. After processing, the groove at the top will rotate downward and the groove at the bottom will rotate upward. The clamps 24 on both sides of the groove will clamp the workpiece. The rotation of the feeding roller 21 is driven by the rotating shaft wheel 12, and the rotating shaft wheel 12 is driven by the driving shaft 13. The driving shaft 13 is controlled by a motor. When the rotating shaft wheel 12 rotates, it will drive the feeding roller 21 to rotate. The motor is timed and driven once at a certain interval.

[0032] When the groove at the top of the feeding roller 21 rotates to the bottom, unloading begins, and the push controller 9 is started. The push controller 9 will control the extension and retraction of the push cylinder group 10. The push cylinder group 10 here is the sum of the cylinder body and the cylinder column. When unloading, the workpiece is pushed out of the groove at the bottom by the cylinder column and the push piece 11, and the workpiece that slides out will fall into the receiving box 5. Then loading begins. A cylinder structure is installed at the bottom of the placement plate 30 in the feeding box 4. When loading, the placement plate 30 and the workpiece on the top are lifted up by the cylinder structure until the topmost workpiece enters the groove. The object sensor 25 in the groove of the feeding roller 21 will sense that a workpiece is approaching. When the object sensor 25 senses that a workpiece is approaching, it will transmit the information to the clamping cylinder through the built-in transmission chip. The clamping cylinder group 26 transmits electrical signals, and the built-in receiving chip of the clamping cylinder group 26 receives the signal transmitted from the object sensor 25. After receiving the signal, the clamping cylinder group 26 controls the cylinder column 27 to extend forward. When the cylinder columns 27 on both sides extend forward at the same time, the clamping piece 24 is driven to extend forward to clamp the workpiece 29 entering the groove. A pressure sensor 28 is installed in the clamping piece 24, which can sense the clamping force on the workpiece 29 in real time. When the clamping force reaches the clamping standard, a stop signal is transmitted to the receiving chip in the clamping cylinder group 26 through the built-in transmission chip. After receiving the stop signal, the clamping cylinder group 26 stops controlling the cylinder column 27 to extend forward and stops clamping inward. After that, it waits for the workpiece 29 in the top groove to be processed, and then the bottom workpiece 29 continues to rotate back to the top. Specific embodiment 2:

[0034] Reference Figure 1-7 Side piles 8 are clamped on both sides between the bracket 1 and the top frame 6, and grooves are opened on the sides of the side piles 8. A lifting controller 14 is installed on the top of the side groove of the side pile 8. The bottom of the lifting controller 14 is electrically connected to a lifting cylinder group 19, and the bottom of the lifting cylinder group 19 is clamped with a mounting joint 15.

[0035] A limit head 2 is installed on one side of the top of the bracket 1. A lifting plate 20 is slidably connected inside the limit head 2. A support clamp 22 is threadedly connected to the top of the lifting plate 20. A driving motor 7 is clamped inside the support clamp 22.

[0036] A transmission device 16 is installed on one side of the driving motor 7 , and a circular saw machine 18 is installed on the back side of the transmission device 16 .

[0037] The inner sides of the transmission device 16 and the circular saw machine 18 are both threadedly connected with a telescopic column 17, and the end of the telescopic column 17 is clamped with the inner side of the mounting joint 15. The transmission device 16 and the circular saw machine 18 are limited and fixed by the telescopic column 17 on the side. The entire cutting assembly can be raised and lowered horizontally to cut the workpiece 29 without manual control.

[0038] When cutting is required, the lifting controllers 14 in the side piles 8 on both sides are controlled to start at the same time. The upgraded controller 14 will control the end of the lifting cylinder group 19 at the bottom to descend. When the end of the lifting cylinder group 19 descends, it will drive the mounting joint 15 to descend, and the entire cutting assembly will also descend with the descent of the mounting joint 15. The precise distance from the workpiece 29 needs to be set in advance, so as to ensure that the cutting assembly can accurately cut the workpiece. The lifting plate 20 and the support clamp 22 in the limit head 2 will limit and clamp the drive motor 7. When the cutting assembly is lifted or lowered, the drive motor 7 will also rise and fall in the limit head 2.

[0039] In summary:

[0040] 1. When the groove at the top of the feeding roller 21 rotates to the bottom, the material is unloaded and the push controller 9 is started. The push controller 9 will control the extension and retraction of the push cylinder group 10. The push cylinder group 10 here is the sum of the cylinder body and the cylinder column. When unloading, the workpiece is pushed out of the groove at the bottom by the cylinder column and the push piece 11. The workpiece that slides out will fall into the material receiving box 5. Then the material is loaded. A cylinder structure is installed at the bottom of the placement plate 30 in the feeding box 4. When loading, the placement plate 30 and the workpiece at the top are lifted up by the cylinder structure until the topmost workpiece enters the groove. The object sensor 25 in the groove of the feeding roller 21 will sense that a workpiece is approaching. When the object sensor 25 senses that a workpiece is approaching, it will send a signal to the clamping gas through the built-in transmission chip. The cylinder group 26 transmits electrical signals, and the built-in receiving chip of the clamping cylinder group 26 will receive the signal transmitted from the object sensor 25. After receiving the signal, the clamping cylinder group 26 will control the cylinder column 27 to extend forward. When the cylinder columns 27 on both sides extend forward at the same time, the clamping piece 24 will be driven to extend forward to clamp the workpiece 29 entering the groove. A pressure sensor 28 is installed in the clamping piece 24, which will sense the clamping force on the workpiece 29 in real time. When the clamping force reaches the clamping standard, a stop signal will be transmitted to the receiving chip in the clamping cylinder group 26 through the built-in transmission chip. After receiving the stop signal, the clamping cylinder group 26 will stop controlling the extension of the cylinder column 27 and stop clamping inward. After that, it will wait for the workpiece 29 in the top groove to be processed, and then the bottom workpiece 29 will continue to rotate back to the top.

[0041] 2. The inner sides of the transmission device 16 and the circular saw machine 18 are both threadedly connected with a telescopic column 17, and the end of the telescopic column 17 is clamped with the inner side of the mounting joint 15. The transmission device 16 and the circular saw machine 18 are limited and fixed by the telescopic column 17 on the side. The entire cutting assembly can be raised and lowered horizontally to cut the workpiece 29 without manual control.

[0042] When cutting is required, the lifting controllers 14 in the side piles 8 on both sides are controlled to start at the same time. The upgraded controller 14 will control the end of the lifting cylinder group 19 at the bottom to descend. When the end of the lifting cylinder group 19 descends, it will drive the mounting joint 15 to descend, and the entire cutting assembly will also descend with the descent of the mounting joint 15. The precise distance from the workpiece 29 needs to be set in advance, so as to ensure that the cutting assembly can accurately cut the workpiece. The lifting plate 20 and the support clamp 22 in the limit head 2 will limit and clamp the drive motor 7. When the cutting assembly is lifted or lowered, the drive motor 7 will also rise and fall in the limit head 2.
