[0023] During operation, the mold part to be turned is first clamped inside the spindle 8, and then the tool to be used is installed inside the tool holder 5. The spindle 8 can be driven to rotate by starting the motor 12, and then moved through the Y-axis frame 4, so that the tool inside the tool holder 5 is close to the outside of the part inside the spindle 8 and slowly contacts the part, thereby realizing the cutting operation of the part.

[0024] The oil injection assembly 13 includes a rotating shaft 1301, which is rotatably mounted inside the positioning frame 19, a second toothed disc 1302 is fixedly mounted on the outer surface of the rotating shaft 1301, a toothed disc 20 is fixedly mounted on the outer surface of the main shaft 8, and a toothed belt 21 is sleeved between the second toothed disc 1302 and the first toothed disc 20.

[0026] A fixing seat 1309 and an oil storage tank 1308 are fixedly installed on the top of the main frame 7, a clamping groove 1310 is provided inside the fixing seat 1309, a clamping plate 1311 is movably clamped inside the clamping groove 1310, one side surface of the clamping plate 1311 is fixedly connected to one end of the connecting plate 1325, a mounting frame 1312 is fixedly installed on the bottom of the clamping plate 1311, a movable tank 1307 is fixedly installed inside the mounting frame 1312, both sides of the movable tank 1307 are provided with fixed pipes 1313, one side surface of the oil storage tank 1308 is fixedly connected to a limiting frame 1326, the fixed pipes 1313 are movably plugged into the inside of the limiting frame 1326, a sealing partition 1316 is movably clamped inside the movable tank 1307, the sealing partition 1316 divides the interior of the movable tank 1307 into a cavity 1317 and a cavity 2 1318, one end of the two fixed pipes 1313 are respectively connected to the sealing partition 1 The two side surfaces of the two fixed pipes 1313 located in the cavity 1317 and the cavity 2 1318 are fixedly connected, and the outer surfaces of the two fixed pipes 1313 located in the cavity 1317 and the cavity 2 1318 are fixedly installed with a check valve 2 1320, and the outer surfaces of the two fixed pipes 1313 located in the cavity 1317 and the cavity 2 1318 are opened with a through hole 1319, and the outer surfaces of the movable tank 1307 located in the cavity 1317 and the cavity 2 1318 are fixedly connected with a connecting pipe 1 1314, and the connecting pipe 1 One end of the connecting pipe 1314 is fixedly connected to one side surface of the oil storage tank 1308, a one-way valve 1315 is fixedly installed on the outer surface of the connecting pipe 1314, one end of the fixed pipe 1313 is fixedly connected to the oil delivery pipe 2 1323, one end of the oil delivery pipe 2 1323 is fixedly connected to the oil delivery pipe 1 1321, the guide rail 3 is a hollow structure, a plurality of oil outlet holes 1322 are opened through the top surface of the guide rail 3, and the oil delivery pipe 1 1321 and the guide rail 3 are connected to each other.

[0027] During operation, when the clamping frame 1305 moves back and forth inside the C-shaped frame 1304, the connecting plate 1325 can drive the connecting plate 1325 to move synchronously, and during the movement, the clamping plate 1311 can be driven to move back and forth inside the clamping groove 1310. Since the movable tank 1307 is fixedly installed on the bottom surface of the clamping plate 1311 through the mounting frame 1312, the clamping plate 1311 can synchronously drive the movable tank 1307 to move back and forth during the movement. When the movable tank 1307 moves back and forth, the space inside the cavity 1317 and the cavity 2 1318 can be enlarged or reduced under the action of the sealing partition 1316. When the space inside the cavity 1317 and the cavity 2 1318 becomes larger, the oil storage tank 1307 can be opened. The lubricating oil inside 08 is sucked into the interior of cavity one 1317 and cavity two 1318 through connecting pipe one 1314. Conversely, when the space inside cavity one 1317 and cavity two 1318 becomes smaller, the lubricating oil sucked into cavity one 1317 and cavity two 1318 can be pushed into the interior of fixed pipe 1313, and then enter into the interior of oil delivery pipe two 1323, and finally enter into the interior of hollow guide rail 3 through oil delivery pipe one 1321, and finally seep out through oil outlet 1322. During the process of cutting parts, that is, during the movement of Y-axis frame 4, it contacts with guide rail 3, thereby realizing automatic oiling operation of guide rail 3. On the one hand, it can provide good protection for guide rail 3 and Y-axis frame 4, and at the same time, it also increases the accuracy of Y-axis frame 4 when moving, thereby improving the accuracy of part processing.

[0028] Through the above, the purpose of automatically oiling the guide rail 3 can be achieved. The lubricating oil injected into the outer surface of the guide rail 3 can be accumulated on the outer surface of the guide rail 3 in the form of dots. Then, when the Y-axis frame 4 moves on the outer surface of the guide rail 3, the lubricating oil in the dots is applied, thereby increasing the lubrication effect between the two and reducing the friction between the two, thereby reducing the wear between the two, increasing the service life and improving the movement accuracy of the Y-axis frame 4.

[0029] The cooling assembly 15 includes two fixed tanks 1501, and the two fixed tanks 1501 are fixedly installed above the main frame 7. The cooling assembly 15 is used to cool the tool and workpiece inside the tool holder 5; The interior of the fixed tank 1501 is movably connected with a sealing plug disc 1513, and a cross mounting bracket 1514 is fixedly installed on the inner wall of the fixed tank 1501. A threaded hole 1515 is provided inside the cross mounting bracket 1514, and a threaded rod 1516 is sleeved on the internal thread of the threaded hole 1515. One end of the threaded rod 1516 is rotatably connected to the surface of one side of the sealing plug disc 1513, and a gear 1517 is fixedly installed on the other end of the threaded rod 1516. An extension rod 1327 is fixedly connected to the bottom surface of the clamping bracket 1305, and a tooth plate 1324 is fixedly installed on the bottom end of the extension rod 1327. The tooth plate 1324 and the gear 1517 are meshed with each other. A connecting pipe 1502 is fixedly connected to the surface of one side of the fixed tank 1501, and one end of the connecting pipe 1502 is fixedly connected to a rectangular tube 1503. A liquid inlet pipe 1504 is fixedly connected to the surface of one side of the tube 1503, one end of the liquid inlet pipe 1504 extends to the interior of the storage chamber 23, a one-way valve three 1505 is fixedly installed on the outer surface of the connecting pipe 1502, a vertical plate 1508 is fixedly installed on the top surface of the oil storage tank 1308, a plug-in frame 1509 is movably plugged into the interior of the vertical plate 1508, a nozzle 1512 is fixedly installed on the bottom surface of the plug-in frame 1509, a liquid outlet pipe 1506 is fixedly connected to the outer surface of the fixed tank 1501, a one-way valve four 1507 is fixedly installed on the outer surface of the liquid outlet pipe 1506, a rectangular tube 2 1511 is fixedly connected to the top of the liquid outlet pipe 1506, a connecting tube 2 1510 is fixedly connected to the bottom surface of the rectangular tube 2 1511, and the other end of the connecting tube 2 1510 is fixedly connected to the top surface of the plug-in frame 1509.

[0030] During operation, when the clamping frame 1305 moves back and forth, it can also synchronously drive the extension rod 1327 to move synchronously. When the extension rod 1327 moves, it can drive the tooth plate 1324 to move, thereby driving the threaded rod 1516 to rotate back and forth inside the threaded hole 1515 under the action of gear 1517. Since the threaded rod 1516 is threadedly sleeved inside the threaded hole 1515, it can drive the sealing plug disc 1513 to move back and forth inside the fixed tank 1501 under the action of the thread. When the sealing plug disc 1513 moves inside the fixed tank 1501 toward the direction of the cross mounting frame 1514, negative pressure can be generated inside the fixed tank 1501, and under the action of the negative pressure, the The cutting fluid inside the storage chamber 23 is sucked into the interior of the fixed tank 1501 through the liquid inlet pipe 1504, the rectangular tube 1503 and the connecting pipe 1502, and when the sealing plug disc 1513 moves inside the fixed tank 1501 in a direction away from the cross mounting frame 1514, the cutting fluid sucked into the interior of the fixed tank 1501 can be pushed into the interior of the liquid outlet pipe 1506, and enters into the interior of the plug-in frame 1509 through the rectangular tube 2 1511 and the connecting tube 2 1510, and finally sprayed downward through the nozzle 1512, that is, sprayed toward the parts being cut inside the spindle 8 and the tools inside the tool holder 5, which on the one hand improves the cutting effect of the parts, and on the other hand can effectively cool the parts and the tools.

[0031] Through the above, during the process of part cutting and oiling, the supply of cutting fluid can be driven at the same time, so that cutting, oiling and cooling can be carried out simultaneously to ensure consistency, thereby improving the overall effect of the device on parts processing.

[0032] The plug-in frame 1509 is plugged into the interior of the vertical plate 1508, and the position of the nozzle 1512, that is, the position where the cutting fluid is sprayed, can be adjusted by moving the plug-in frame 1509 inside the vertical plate 1508, thereby further improving the overall practicality of the device.

[0033] A vibration assembly 22 is arranged inside the main housing 1, and the vibration assembly 22 includes a second rotating shaft 2201, one end of the second rotating shaft 2201 extends to the inside of the storage chamber 23, and the other end of the second rotating shaft 2201 is located outside the main housing 1, and the outer surface of the second rotating shaft 2201 located inside the main housing 1 is fixedly installed with a mounting collar 2204, and the bottom surface of the mounting collar 2204 is fixedly installed with a mixing frame 2205, and the bottom surface of the mixing frame 2205 is fixedly installed with a plate brush 2206, and the output end of the motor 12 is fixedly installed with a pulley 16, and the end of the second rotating shaft 2201 located outside the main housing 1 is fixedly installed with a pulley 3 2202, and between the pulley 3 2202 and the pulley 16 A transmission belt 2203 is sleeved thereon, a gear 3 2215 is fixedly installed on the outer surface of the rotating shaft 2201 located below the guide plate 9, a positioning plate 2207 is fixedly installed inside the main shell 1, a plug-in shaft 2211 is movably inserted inside the positioning plate 2207, a strike plate 2214 is fixedly installed on the top of the plug-in shaft 2211, a toggle frame 2212 is fixedly installed on the bottom end of the plug-in shaft 2211, a rotating shaft 3 2208 is installed below the positioning plate 2207, a gear 2 2209 is fixedly installed on one end of the rotating shaft 3 2208, a toggle shaft 2210 is fixedly installed on one side surface of the gear 2209, and the gear 2209 and the gear 3 2215 are meshed with each other.

[0034] During operation, when the motor 12 is started, it can drive the rotating shaft 2201 to rotate under the action of the pulley 16, the transmission belt 2203 and the pulley 3 2202, thereby driving the mounting ring 2204 and the mixing frame 2205 to stir inside the storage chamber 23, which can effectively prevent the cutting fluid from settling inside the storage chamber 23, thereby affecting the subsequent cutting effect.

[0038] When the clamping frame 1305 moves back and forth inside the C-shaped frame 1304, the connecting plate 1325 can drive the connecting plate 1325 to move synchronously under the action of the connecting plate 1325, and drive the clamping plate 1311 to move back and forth inside the clamping groove 1310, so that the lubricating oil inside the oil storage tank 1308 is sucked into the inside of the cavity 1317 and the cavity 2 1318 through the connecting pipe 1314, and finally the lubricating oil sucked into the cavity 1317 and the cavity 2 1318 is pushed into the inside of the fixed pipe 1313 and discharged through the oil outlet hole 1314. 322 seeps out to realize the automatic oiling operation of the guide rail 3. When the clamping frame 1305 moves back and forth, it can synchronously drive the extension rod 1327 to move synchronously, so that negative pressure is generated inside the fixed tank 1501, and the cutting fluid inside the storage chamber 23 is sucked into the interior of the fixed tank 1501 through the liquid inlet pipe 1504, the rectangular tube 1503 and the connecting pipe 1502, and the sucked cutting fluid is pushed into the interior of the liquid outlet pipe 1506, and finally sprayed downward through the nozzle 1512, which can effectively cool the parts and the tool.
