The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model embodiment provides a compound type cutting type CNC lathe, such as Figure 1-4As shown, a composite tool-feeding CNC lathe comprises a base 1, a clamping jaw 5 and a lathe body 12, a liquid storage chamber 2 is provided inside the base 1, a liquid extraction tube 3 is connected to one side of the base 1, a liquid discharge tube 14 is connected to the other side of the base 1, a lathe body 12 is installed at the top of the base 1, and a side door 6 is installed on one side of the lathe body 12, a clamping jaw 5 is installed on one side of the lathe body 12, a tool-feeding platform 10 is installed on the other side of the lathe body 12, a cleaning mechanism 8 is provided on the top of the lathe body 12, a control panel 11 is installed on the top of one side of the lathe body 12, a liquid extraction pump 16 is installed on one side of the liquid extraction tube 3, and the liquid extraction pump 16 is installed on the other side of the lathe body 12. A water pipe 17 is connected to the top, a folding pipe 7 is connected to one side of the water pipe 17, and a liquid spray head 9 is connected to the bottom end of one side of the folding pipe 7. A visual window 15 is arranged inside the side door 6. A guide plate 13 is connected to the bottom end of the inside of the lathe body 12, and a filter structure 4 is arranged inside the guide plate 13. The filter structure 4 includes a fixed frame 401, a positioning column 402, a support plate 403, a coarse filter screen 404, a first magnet block 405, a first fixed plate 406, a fine filter screen 407, a second magnet block 408 and a second fixed plate 409. The support plates 403 are all fixed on the inner wall of the guide plate 13, and a positioning column 402 is inserted inside the support plate 403.

[0024] The working principle of a composite tool-feeding CNC lathe is as follows: the device is placed in a designated position and powered by an external power supply. The workpiece to be cut can be clamped and fixed on the clamping jaw 5 by opening the side door 6. Then the control panel 11 can control the tool-feeding platform 10 to drive the turning tool to move flexibly forward, backward, left and right to cut the workpiece. At the same time, the liquid pump 16 is started to extract the cutting coolant in the liquid storage chamber 2 through the liquid extraction pipe 3 and introduce it into the folding tube 7 through the water pipe 17, and spray it onto the workpiece and the turning tool through the liquid spray head 9 to cool them to prevent the temperature from being too high and affecting the normal operation of the turning tool. Then, the coolant sprayed by the liquid spray head 9 can be recovered through the guide plate 13 and introduced into the liquid storage chamber 2 for reuse. When the coolant needs to be replaced, the old coolant can be discharged and replaced by opening the valve on the drain pipe 14.

[0025] It should be noted that, since the coolant on the existing compound tool-feeding CNC lathe is generally directly introduced to flow back to the liquid storage chamber 2, the cutting chips mixed in the coolant will easily block the channels of the liquid extraction pipe 3 and the liquid extraction pump 16. Therefore, in order to solve the problem that the existing compound tool-feeding CNC lathe cannot filter the chips, the present solution adds a filtering structure 4 to facilitate the filtering and separation of the chips in the returning coolant.

[0026] In a further preferred embodiment of the present invention, Figure 1-4As shown: the top of the positioning column 402 is connected to the fixed frame 401, and the inner wall of the top of the fixed frame 401 is connected to the first fixed plate 406, the top of the first fixed plate 406 is placed with a coarse filter 404, and the inside of both sides of the coarse filter 404 are inlaid with first magnet blocks 405, the inner wall of the bottom end of the fixed frame 401 is connected to the second fixed plate 409, and the top of the second fixed plate 409 is placed with a fine filter 407, and the inside of both sides of the fine filter 407 are inlaid with second magnet blocks 408, the first fixed plate 406 and the second fixed plate 409 are both made of iron, the diameter of the positioning column 402 is smaller than the inner diameter of the support plate 403, the coarse filter 404 and the fine filter 407 are located on the same vertical line, and the positioning columns 402 are symmetrically distributed on both sides of the bottom end of the fixed frame 401.

[0027] Specifically, in the present embodiment, when it is necessary to filter the cutting coolant that flows back into the liquid storage chamber 2, the fixing frame 401 can be positioned in the guide plate 13 by moving the fixing frame 401 to drive the positioning column 402 to align and insert into the support plate 403, and then the coolant that has flushed the workpiece and the turning tool enters the fixing frame 401, and successively passes through the coarse filter 404 and the fine filter 407 with gradually decreasing filtration pores to filter the debris, so that the coarse filter 404 and the fine filter 407 filter and separate the debris in the coolant from the coolant to prevent it from flowing back into the storage chamber with the coolant The liquid chamber 2 causes blockage in the liquid extraction pipe 3 and the liquid extraction pump 16 to ensure that the liquid extraction pipe 3 and the side door 6 can normally transport the coolant. The positioning column 402 is driven to leave the support plate 403 by pulling up the fixed frame 401, and is completely lifted out of the guide plate 13 to stop. Then, the coarse filter screen 404 and the fine filter screen 407 are pulled in turn to drive the first magnet block 405 and the second magnet block 408 to separate from the first fixed plate 406 and the second fixed plate 409 respectively. The coarse filter screen 404 and the fine filter screen 407 can be removed from the fixed frame 401 to facilitate cleaning of the debris filtered on their surfaces.

[0028] In a further preferred embodiment of the present invention, Figure 1-4 As shown: the cleaning mechanism 8 includes a hydraulic push rod 801, a limiting cap 802, a buffer pad 803, a connecting rod 804, a guide rod 805 and a sponge brush 806.

[0029] Specifically, in the present embodiment, when it is necessary to use the viewing window 15 to observe the cutting of the workpiece in the lathe body 12, the sponge brush 806 is driven to move up and down flexibly by starting the hydraulic push rod 801, so that the sponge brush 806 in contact with the viewing window 15 can wipe and clean the cutting cleaning liquid splashed on the inner side of the viewing window 15, thereby ensuring the clarity of the viewing window 15, so that the staff can clearly view the processing of the workpiece in the lathe body 12. At the same time, the guide rod 805 slides along the inner wall of the lathe body 12 for guidance as the sponge brush 806 moves, so as to ensure the stability of the sponge brush 806. The guide rod 805 can be limited by the setting of the limit cap 802 to prevent the guide rod 805 from completely sliding out of the interior of the lathe body 12. At the same time, the buffer pad 803 can buffer the impact force generated by the limit cap 802 as the guide rod 805 moves downward, so as to prevent the limit cap 802 from directly hitting the lathe body 12 and causing damage.
