[0020] The working principle and beneficial effects of the above technical solution are as follows: by injecting coolant into the interior of the water tank 4, and then using the hydraulic chuck 7 to fix the workpiece, and then using the tailstock 11 to support the tail of the workpiece, the device is connected to the industrial computer, and the industrial computer controls the spindle box 6 to drive the hydraulic chuck 7 to rotate, and at the same time the CNC tool holder 3 drives the tool to move to cut the workpiece, and the coolant and debris are received through the slag discharge structure 2, the debris in the coolant is filtered and the debris is discharged.

[0021] like Figure 1 and Figure 2 As shown, in one embodiment: the feed assembly includes a support plate 14 installed on the top of the bed 1, a screw rod 15 fixed inside one side of the support plate 14, a CNC tool holder 3 installed on the top of the support plate 14, a reciprocating table 13 installed on the other side of the top of the support plate 14, and a tailstock 11 fixed on the top of the reciprocating table 13.

[0022] The working principle and beneficial effects of the above technical solution are: the tool is driven to move by the feed assembly to perform precise cutting on the workpiece.

[0023] like Figure 3 and Figure 4As shown, in one embodiment: the circulation component includes a water tank 4 installed at the bottom of the support plate 14, a water pump 19 installed on one side of the water tank 4, a connecting pipe 18 connected to the top of the water pump 19, a reciprocating structure 9 arranged at the top of the ceiling 20, and a nozzle 17 arranged at the bottom of the reciprocating structure 9.

[0024] The working principle and beneficial effects of the above technical solution are as follows: the coolant inside the water tank 4 is extracted by the water pump 19 and introduced into the interior of the nozzle 17 through the connecting pipe 18, and then the nozzle 17 sprays the coolant to cool the cutting part, and the reciprocating structure 9 drives the nozzle 17 to swing left and right to expand the spraying range of the nozzle 17 and ensure the spraying effect, and the cooling structure 12 is used to cool the coolant flowing through the connecting pipe 18 to improve the cooling effect of the coolant, and the splash-proof structure 8 is used to shield one side of the device to prevent the coolant and debris from splashing out during the processing.

[0025] like Figure 3 and Figure 6 As shown, in one embodiment: the slag discharge structure 2 is fixed to the collecting trough 201 inside the support plate 14, the filter plate 5 is installed inside one side of the collecting trough 201, the discharge port 202 is fixed on one side of the collecting trough 201, a transmission wheel 206 rotatably connected to the inside of the support plate 14, a driving motor 205 is installed on one side of the support plate 14 and the rotating end is connected to the transmission wheel 206, a transmission belt 203 is sleeved on the outside of the transmission wheel 206, a scraper 204 is fixed on the outside of the transmission belt 203, and a driven wheel 207 is arranged on one side of the transmission belt 203 and rotatably connected to the support plate 14.

[0026] The working principle and beneficial effects of the above technical solution are as follows: the coolant and the debris are collected through the collection tank 201, and the filter plate 5 filters the coolant on the surface of the collection tank 201, so that the coolant passes through the filter plate 5 and falls into the inside of the water tank 4, and the debris is accumulated in the inside of the collection tank 201. Since the filter plate 5 is placed at an angle, the debris on the surface of the filter plate 5 is easily washed by the coolant and rolls to the bottom of the collection tank 201, so that the filter plate 5 is not easy to be blocked during use. When too much debris is accumulated at the bottom of the collection tank 201, the debris on the surface of the filter plate 5 is easily washed by the coolant and rolls to the bottom of the collection tank 201. When debris is collected, the drive motor 205 is started to drive the transmission wheel 206 to move, so that the transmission wheel 206 drives the scraper 204 to move inside the collection tank 201 through the transmission wheel 206, and the scraper 204 scrapes the debris at the bottom of the collection tank 201 to move to the discharge port 202 and be discharged. In this process, the coolant mixed in the debris can flow out through the gap between the scraper 204 and the collection tank 201, thereby reducing the waste of coolant. By placing a container on one side of the discharge port 202, the debris can be collected.

[0027] like Figure 3 and Figure 6As shown, in one embodiment: a plurality of scrapers 204 are arranged on the outside of the transmission belt 203, and the plurality of scrapers 204 are evenly spaced on the outside of the transmission belt 203, and the front cross section of the collecting trough 201 is a "V"-shaped structure.

[0028] The working principle and beneficial effects of the above technical solution are as follows: the “V”-shaped structure allows the debris to be easily accumulated at the bottom of the collecting tank 201 , while the coolant passes through the filter plate 5 during the flow.

[0029] like Fig. 9 As shown, in one embodiment: the splash-proof structure 8 includes a vertical plate 801 fixed to one side of the top of the ceiling 20, a multi-stage cylinder 802 rotatably connected to the top of one side of the vertical plate 801, a sliding cover 805 rotatably connected to the telescopic end of the multi-stage cylinder 802, moving blocks 804 fixed to both sides of the sliding cover 805, a rotating seat 808 installed at the bottom of the ceiling 20, a stop plate 807 fixed to one side of the rotating seat 808, a fixed cover 806 installed at the bottom of the rotating seat 808, and a guide shell 803 fixed to the top of the fixed cover 806 and slidably connected to the moving block 804.

[0030] The working principle and beneficial effects of the above technical solution are as follows: start the multi-stage cylinder 802 to extend, so that the multi-stage cylinder 802 pushes the sliding cover 805 to move, and at the same time the sliding cover 805 pushes the fixed cover 806 to flip downward around the rotating seat 808 and contact the stop plate 807, and then the stop plate 807 is used to limit the flipping position of the fixed cover 806. At the same time, as the multi-stage cylinder 802 continues to extend, the sliding cover 805 drives the moving block 804 to slide inside the guide shell 803, so that the sliding cover 805 moves downward to cover one side of the device to prevent the splashing of debris and coolant.

[0031] like Fig. 9 As shown, in one embodiment: the sliding cover 805 forms a rotating structure with the ceiling 20 through the rotating seat 808, and the sliding cover 805 and the fixed cover 806 form a sliding structure.

[0032] like Figure 7 and Figure 8 In one embodiment, the cooling structure 12 includes a cooling shell 1201 installed on one side of the ceiling 20, a connecting port 1207 fixed at both ends of the cooling shell 1201 and connected to the connecting pipe 18, a guide plate 1208 fixed inside the cooling shell 1201, a semiconductor refrigeration plate 1203 installed on one side of the cooling shell 1201, a heat sink 1204 installed on one side of the semiconductor refrigeration plate 1203, a mounting frame 1206 detachably mounted on one side of the heat sink 1204, a pressure plate 1202 fixed on both sides of the mounting frame 1206 and connected to the ceiling 20, and a fan 1205 installed inside the mounting frame 1206.

[0033] The working principle and beneficial effects of the above technical scheme are as follows: the coolant is introduced into the interior of the cooling shell 1201 through the connecting port 1207 at one end of the cooling shell 1201, and the semiconductor refrigeration plate 1203 is started to cool the interior of the cooling shell 1201 to reduce the temperature of the coolant. At the same time, the guide plate 1208 guides the coolant inside the cooling shell 1201 to extend the path of the coolant inside the cooling shell 1201 and improve the cooling effect. At the same time, the heat sink 1204 exports the heat from the semiconductor refrigeration plate 1203, and the fan 1205 is used to dissipate the heat from the heat sink 1204 to ensure the normal operation of the semiconductor refrigeration plate 1203. The low-temperature coolant is re-introduced into the interior of the connecting pipe 18 through the connecting port 1207 for use. The heat sink 1204, the semiconductor refrigeration plate 1203 and the cooling shell 1201 are pressed tightly by the pressing plate 1202 to improve the thermal conductivity.

[0034] like Figure 5 As shown, in one embodiment: the reciprocating structure 9 includes a moving sleeve 903 sliding on the outside of the moving rod 10, a moving shell 901 fixed on one side of the moving sleeve 903, a sliding rod 902 rotatably connected to the inside of the moving shell 901, a support frame 904 fixed to the bottom end of the sliding rod 902 and connected to the nozzle 17, a fixed frame 907 fixed to the bottom end of the moving shell 901, a reduction motor 908 installed on one side of the fixed frame 907, a rocker arm 906 rotatably connected to the other side of the fixed frame 907 and connected to the rotating end of the reduction motor 908, and a sliding sleeve 905 rotatably connected to one side of the rocker arm 906 and slidably connected to the sliding rod 902.

[0035] The working principle and beneficial effects of the above technical solution are as follows: starting the reduction motor 908 to rotate, so that the reduction motor 908 drives the rocker arm 906 to rotate, and the rocker arm 906 drives the sleeve 905 to move. At the same time, since the sleeve 905 slides on the outside of the slide rod 902, the rocker arm 906 drives the sleeve 905 to slide back and forth on the outside of the slide rod 902 during the rotation process, so that the sleeve 905 pushes the slide rod 902 to swing back and forth at the bottom of the movable shell 901, and drives the nozzle 17 to spray reciprocatingly, thereby expanding the range of spray cooling.

[0036] like Figure 5 As shown, in one embodiment: a connecting frame 16 connected to the CNC tool holder 3 is installed on one side of the moving shell 901, and a sliding structure is formed between the moving sleeve 903 and the moving rod 10.

[0037] The working principle and beneficial effects of the above technical solution are as follows: since the connecting frame 16 is connected to the CNC tool holder 3, when the CNC tool holder 3 moves left and right, the CNC tool holder 3 drives the movable sleeve 903 to slide on the outside of the movable rod 10 through the connecting frame 16, so that the movable shell 901 and the CNC tool holder 3 move synchronously.

[0038] Specifically, when the CNC machine tool with reciprocating cooling is in use: coolant is injected into the water tank 4, and then the hydraulic chuck 7 is used to fix the workpiece for processing, and then the tailstock 11 is used to resist the tail of the workpiece for processing, and the device is connected to the industrial computer, and the spindle box 6 is controlled by the industrial computer to drive the hydraulic chuck 7 to rotate, and at the same time, the CNC tool holder 3 drives the tool to move to perform cutting processing on the workpiece, and the coolant in the water tank 4 is extracted by the water pump 19 and introduced into the inside of the nozzle 17 through the connecting pipe 18, and then the nozzle 17 sprays the coolant to cool the cutting part, and the reciprocating structure 9 drives the nozzle 17 to swing left and right to expand the spraying range of the nozzle 17 and ensure the spraying effect, and the cooling structure 12 is used to cool the coolant flowing through the connecting pipe 18 to improve the cooling effect of the coolant, and the splash-proof structure 8 is used to shield one side of the device so that the coolant and debris are not easy to splash out during the processing, and the coolant and debris are received by the slag discharge structure 2, and the debris in the coolant is filtered and discharged; The coolant and the debris are collected through the collecting tank 201, and the filter plate 5 filters the coolant on the surface of the collecting tank 201, so that the coolant passes through the filter plate 5 and falls into the water tank 4, and the debris is accumulated in the collecting tank 201. Since the filter plate 5 is placed at an angle, the debris on the surface of the filter plate 5 is easily washed by the coolant and rolls to the bottom of the collecting tank 201, so that the filter plate 5 is not easily blocked during use. When too much debris is accumulated at the bottom of the collecting tank 201, the driving motor 205 is started to drive the transmission wheel 206 to move, so that the transmission wheel 206 drives the scraper 204 to move inside the collecting tank 201 through the transmission wheel 206, and the scraper 204 scrapes the debris at the bottom of the collecting tank 201 to move to the discharge port 202 and discharge. In this process, the coolant mixed in the debris can flow out through the gap between the scraper 204 and the collecting tank 201, thereby reducing the waste of coolant. The debris can be collected by placing a container on one side of the discharge port 202; During the processing, the multi-stage cylinder 802 is started to extend, so that the multi-stage cylinder 802 pushes the sliding cover 805 to move, and at the same time, the sliding cover 805 pushes the fixed cover 806 to turn downward around the rotating seat 808 and contact the stop plate 807, and then the stop plate 807 is used to limit the turning position of the fixed cover 806. At the same time, as the multi-stage cylinder 802 continues to extend, the sliding cover 805 drives the moving block 804 to slide inside the guide shell 803, so that the sliding cover 805 moves downward to cover one side of the device to prevent the splashing of debris and coolant; The coolant is introduced into the interior of the cooling shell 1201 through the connection port 1207 at one end of the cooling shell 1201, and the semiconductor refrigeration sheet 1203 is started to cool the interior of the cooling shell 1201 to reduce the temperature of the coolant. At the same time, the guide plate 1208 guides the coolant inside the cooling shell 1201 to extend the path of the coolant inside the cooling shell 1201 and improve the cooling effect. At the same time, the heat sink 1204 removes the heat inside the semiconductor refrigeration sheet 1203, and the fan 1205 is used to dissipate the heat from the heat sink 1204 to ensure the normal operation of the semiconductor refrigeration sheet 1203. The low-temperature coolant is re-introduced into the interior of the connecting pipe 18 through the connection port 1207 for use. The heat sink 1204, the semiconductor refrigeration sheet 1203 and the cooling shell 1201 are tightly fitted together by pressing the pressing plate 1202 to improve the heat conduction effect. During the spraying process, the reduction motor 908 is started to rotate, so that the reduction motor 908 drives the rocker arm 906 to rotate, and the sliding sleeve 905 is moved by the rocker arm 906. At the same time, since the sliding sleeve 905 slides on the outside of the sliding rod 902, the rocker arm 906 drives the sliding sleeve 905 to slide back and forth on the outside of the sliding rod 902 during the rotation process, so that the sliding sleeve 905 pushes the sliding rod 902 to swing back and forth at the bottom of the movable shell 901, and drives the nozzle 17 to spray reciprocally, thereby expanding the range of spray cooling.
