[0029] The first sliding groove plate 12 is slidably connected with a first sliding block 24, the first sliding block 24 is slidably connected with a poking rod extension rod 22, the poking rod extension rod 22 is internally fixedly installed with a motor 31 at one end, the motor 31 output shaft is sleeved with a first bevel gear 33, the poking rod extension rod 22 is externally rotatably connected with a twisted scrap hook 30 at one end, the twisted scrap hook 30 extends into the interior of the end of the poking rod extension rod 22 at one end, the twisted scrap hook 30 is fixedly connected with a second bevel gear 34 at one end, the first bevel gear 33 and the second bevel gear 34 are engaged together; The position of the twisted scrap hook 30 is located directly above the tool on the fixed table 8, when the tool is machining a workpiece, the bed moving device 2 moves to the surface of the workpiece, so that the tool is in the process of machining, the tool generates scrap on the surface of the workpiece, and the twisted scrap hook 30 is directly above the tool, the rear drive motor 31 is rotated, so that the motor 31 drives the first bevel gear 33 to rotate, the first bevel gear 33 rotates under the action of engaging the second bevel gear 34, so that the second bevel gear 34 rotates, and the twisted scrap hook 30 rotates, and when the tool cuts the workpiece material, if the tool itself is intact, the cutting process will be relatively smooth, the scrap will be continuously connected together, and the tool will be adhered in a spiral shape, but in this way, the cutting fluid is difficult to cool the tool, therefore, when the tool is machining the workpiece, the end of the scrap is first matched with the rotating path of the twisted scrap hook 30, so that the scrap is wound on the twisted scrap hook 30 in the process of rotating the twisted scrap hook 30, the tool surface machining gap is improved, and the possibility of adhering scrap on the tool surface is reduced.

[0030] In the process of machining, when the tool cutting depth is too large, the twisted scrap hook 30 more or less contacts the workpiece itself, therefore, in the process that the twisted scrap hook 30 contacts the workpiece, the first sliding groove plate 12 end presents a torsion, so as to realize a lever effect, the teeth 1101 at the top of the first sliding groove plate 12 and the teeth 1101 at the bottom of the pressing plate 11 are separated from each other, and are re-engaged after being separated, in this process, the first sliding groove plate 12 rotates, the first spring 21 is compressed, and then restores to the original state after the two teeth 1101 are re-engaged, the pressing plate 11 is used to limit the recovery distance of the first spring 21, so that the twisted scrap hook 30 and the first sliding groove plate 12 together expand the space at the top of the tool, the tool cutting depth is controllable and continuously changed, the workpiece shape is processed into different types when the machine tool is machining the workpiece, and the machine tool use prospect is improved.

[0031] Further, the installation plate is fixedly installed outside the poking rod extension rod 22, a spiral cutter 29 is rotatably connected to the side of the installation plate close to the twisted scrap hook 30, and a belt 32 is sleeved between the twisted scrap hook 30 and the spiral cutter 29. When the motor 31 rotates, the twisted scrap hook 30 is rotated, and at the same time, the twisted scrap hook 30 drives the spiral cutter 29 to rotate through the belt 32. With the processing time, the thickness of the scrap wound around the twisted scrap hook 30 will inevitably increase, so it is necessary to quickly clean it, so as to avoid shielding the cutter again. When the scrap wound on the twisted scrap hook 30 reaches a certain thickness and contacts the spiral cutter 29, the spiral cutter 29 is in a spiral shape. In the process of rotating, the position of the cutting edge is not uniform, and the effect of beveling is achieved, so as to facilitate the quick cleaning of the scrap wound on the twisted scrap hook 30, and prevent the too much scrap from causing inconvenience to processing.

During processing, the surface of the cutter can be preferentially cooled, and at the same time, the effect of cleaning the cutter surface with small particle size scrap is also achieved. After the scrap wound on the twisted scrap hook 30 is cleaned by the spiral cutter 29, it falls into the distribution hopper 28. The distribution hopper 28 and the suction pipe 25 are connected, so that the scrap in the distribution hopper 28 is brought into the outside of the machine tool through the suction pipe 25, improving the cleanliness of the machine tool.

[0033] Further, the second sliding block 26 and the first sliding groove plate 12 are fixedly connected with the second spring 27, one side of the first sliding groove plate 12 is fixedly provided with the first air cylinder 16, and the output end of the first air cylinder 16 and the poking rod extension rod 22 are fixed together. If the twisted scrap hook 30 cannot cover the position above the cutter, the output end of the first air cylinder 16 can be manually controlled to calibrate the position of the poking rod extension rod 22, so that the twisted scrap hook 30 covers the position above the cutter.

[0034] Further, the first sliding groove plate 12 is fixedly provided with the second sliding groove plate 13 on the top, the second sliding groove plate 13 is slidably connected with the second air cylinder 17, and the output end of the second air cylinder 17 and the poking rod extension rod 22 are connected together. During processing, if the twisted scrap hook 30 is not long enough to cover the position above the cutter, the second air cylinder 17 can be used to extend to control the distance of the poking rod extension rod 22 from the position above the cutter.

[0035] Further, the other end of the poking rod extension rod 22 is fixedly connected with a poking rod 15, one end of the poking rod 15 is fixedly installed with a light emitter 14, one end of a marking platform 3 fixedly installed on one side of the top of the workbench 1 is fixedly installed with a contrast cone 7, one side of the outside of the workbench 1 is fixedly installed with a control box 6, one side of the control box 6 is fixedly installed with a main shaft 5, and the axis of the contrast cone 7 and the main shaft 5 coincide together.

[0036] The light emitter 14 selects to use a conspicuous red light, after the coordinate platform 4 and the moving coordinate system of the moving platform 401 are determined, the first cylinder 16 is started to perform telescopic movement in the background to align the head end of the light emitter 14 with the contrast cone 7, so that the red light point is shot to the tip area of the contrast cone 7, and the poking rod extension rod 22 is located in the position directly above the cutter of the fixed platform 8, thereby effectively improving the range of the scrap hook 30 for pulling the scrap.

[0037] Further, the moving platform 401 is fixedly installed with a fixed rod 18 near the connecting disc 10, the fixed rod 18 is slidably connected with a lifting rod 19, the top of the lifting rod 19 is fixedly installed with a first air pipe 20, one end of the first air pipe 20 is connected with a blowing machine pipeline, the other end is fixedly installed with a spray head, the position of the spray head is located directly above the scrap hook 30, if the cutting angle of the cutter is not controlled well and changes when cutting the workpiece, the generated scrap may not be connected together when cutting the surface of the workpiece, at this time, a large amount of broken scrap covers the surface of the cutter and the workpiece, and the first air pipe 20 can be driven by the background to work, and the spray head sprays the gas-liquid mixture to the workpiece and the cutter, thereby reducing the possibility of the scrap adhering to the cutter.

[0038] Further, the other end of the scrap hook 30 is fixedly connected with a distribution tooth 35, the distribution tooth 35 has a plurality of teeth with equal distances, and the plurality of teeth are used for separating the scrap wound on the scrap hook 30; the material of the scrap hook 30 is made of an anti-skid material, so as to prevent the thickness of the scrap wound on the scrap hook 30 at the same position from being too large, thereby reducing the cooling area of the upper part of the cutter.
