[0002] Composite machining is one of the most popular machining processes in the international machining field. It is an advanced manufacturing technology that combines several different machining processes on a single machine tool. The most widely used and most challenging composite machining is mill-turn machining. A mill-turn machining center is essentially a combination of a CNC lathe and a machining center. Among these, mill-turn machining centers are the fastest-growing and most widely used CNC equipment in composite machining. Machine tool integration is one of the important directions for machine tool development. Composite machine tools include various forms such as mill-turn machining, mill-turn grinding machining, milling grinding machining, cutting and 3D printing machining, cutting and ultrasonic vibration machining, and laser and stamping machining. The purpose of integration is to make a single machine tool multifunctional, capable of completing multiple tasks in one setup, improving machining efficiency and accuracy, shortening the product manufacturing process chain, and increasing production efficiency. Mill-turn machining can complete all or most of the machining processes in one setup, thereby greatly shortening the product manufacturing process chain.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1:

[0034] A preferred embodiment of the parallel-structured dual-spindle turning and milling machine tool provided by the present invention is as follows: Figures 1 to 11 As shown: A parallel structure dual-spindle turning and milling composite machine tool includes a machining chamber 1 and a milling cutter 2. A fixing plate 3 is fixedly installed on the inner wall of the machining chamber 1, and a disassembly and assembly mechanism 4 is provided between the milling cutter 2 and the fixing plate 3.

[0035] The disassembly and assembly mechanism 4 includes a mounting plate 401 and a pin 408. A milling cutter 2 is fixedly mounted on one side of the mounting plate 401. A plug 414 is fixedly mounted on one side of the fixing plate 3, and the plug 414 is inserted into a slot on the other side of the mounting plate 401. A fixing post 402 passes through the mounting plate 401 and is rotatably connected to the mounting plate 401 via a bearing. A retaining plate 404 is fixedly mounted on one end of the fixing post 402. A post hole 403 is opened on one side of the fixing plate 3, and a retaining groove 405 is fixedly mounted on the inner wall of the post hole 403. The fixing post 402 is inserted into the post hole 403, and the retaining plate 404 is fixedly mounted on one end of the fixing post 402. The retaining plate 404 is engaged in the retaining groove 405. A plate groove 406 is opened on the inner wall of the post hole 403, and a shrinkage groove 409 is opened on the inner wall of the post hole 403. The pin 408 movably passes through the top of the fixing plate 3 and extends into the shrinkage groove. In 409, a pull plate 413 is fixedly installed at the top of the pin 408, and a rotating plate 407 is fixedly installed at the other end of the fixed column 402. By setting the pull plate 413, it is convenient for personnel to pull the pin 408 by pulling the pull plate 413. By setting the rotating plate 407, it is convenient for personnel to rotate the fixed column 402 by rotating the rotating plate 407, thereby facilitating operation. A pin groove 402 is opened on the outer wall of the fixed column 402, and the pin 408 is inserted into the pin groove 402. The fixed column 402 is adapted to the column hole 403. The clamping plate 404 is adapted to the plate groove 406 and the clamping groove 405. The pin 408 is adapted to the pin groove 412. A baffle 411 is fixedly sleeved on the outer wall of the pin 408. A spring 410 is surrounded on the outer wall of the pin 408. One end of the spring 410 is fixedly installed on the top of the baffle 411, and the other end of the spring 410 is fixedly installed on the inner wall of the shrinkage groove 409.

[0036] Pulling the pull plate 413 causes the pin 408 to move upward. The pin 408 then causes the baffle 411 to compress the spring 410, disengaging the pin 408 from the pin groove 412. When the pin 408 is completely disengaged from the pin groove 412, the rotating plate 407 can be rotated, causing the fixed column 402 to rotate.

[0037] The fixed post 402 drives the clamping plate 404 to rotate, causing the clamping plate 404 to rotate 90 degrees in the clamping groove 405. When the clamping plate 404 is parallel to the plate groove 406, the clamping plate 404 no longer limits the fixed post 402, and the fixed post 402 can be pulled out from the post hole 403, so that the mounting plate 401 can be detached from the fixed plate 3, thereby completing the disassembly of the milling cutter 2. This mechanism facilitates the disassembly and assembly of the milling cutter 2 by personnel, improves the efficiency of disassembly and assembly of the milling cutter 2, and thus improves the working efficiency of the machine tool. It solves the problem that most existing milling cutters are installed using fixing bolts, which requires specific wrenches for disassembly and assembly, resulting in high limitations in disassembly and assembly and affecting the efficiency of disassembly and assembly. Example 2:

[0038] Based on Embodiment 1, a preferred embodiment of the parallel-structured dual-spindle milling and turning machine tool provided by the present invention is, for example... Figures 1 to 11 As shown: A cooling mechanism 5 and a connecting pipe 505 are installed at the top of the processing chamber 1. The cooling mechanism 5 includes a water tank 501, with an inlet pipe connected to the top of the water tank 501. A water pump 602 is fixedly installed at the bottom of the inner wall of the water tank 501. A suction pipe is connected to the input end of the water pump 602, and a guide pipe 503 is connected to the output end of the water pump 602. A hollow plate 504 is fixedly installed at the top of the inner wall of the processing chamber 1. The connecting pipe 505 passes through the bottom of the hollow plate 504, and the outer wall of the connecting pipe 505 is rotatably connected to the hollow plate 504 through a bearing. A sealing gasket 7 is fixedly installed at the bottom of the hollow plate 504. The sealing gasket 7 is movably sleeved on the outer wall surface of the connecting pipe 505. The sealing gasket 7 is made of wear-resistant rubber to improve its service life. By setting the sealing gasket 7, the sealing performance between the connecting pipe 505 and the hollow plate 504 can be increased, preventing water from flowing through the connecting pipe 505. Leakage occurs at the gap between pipe 505 and hollow plate 504, resulting in incomplete utilization of water resources. Atomizing nozzle 506 is connected to the bottom of pipe 505. A partition box 508 is fixedly installed at the bottom of hollow plate 504. A motor 507 is fixedly installed on the inner wall of partition box 508. A rotating shaft 509 is fixedly installed at the output end of motor 507. The rotating shaft 509 movably passes through the bottom of partition box 508. A gear 1 510 is fixedly installed at the bottom of rotating shaft 509. A gear 2 511 is fixedly sleeved on the outer wall of pipe 505. Gear 1 510 and gear 2 511 mesh. Water guide pipe 1 503 is fixedly installed through the bottom of water tank 501 and the top of processing chamber 1 and connected to hollow plate 504. By setting partition box 508, motor 507 can be supported and protected, ensuring stable output of motor 507 and normal service life of motor 507.

[0039] Start water pump 502 to draw water from water tank 501 through suction pipe 1, then transport it to hollow plate 504 through guide pipe 503, and then spray it out from atomizing nozzle 506 through connecting pipe 505. Start motor 507, which drives shaft 509 to rotate. Shaft 509 drives gear 510 to rotate, gear 510 drives gear 511 to rotate, gear 511 drives connecting pipe 505 to rotate, and connecting pipe 505 drives atomizing nozzle 506 to rotate. This makes the water sprayed from atomizing nozzle 506 spray a wider range under the action of centrifugal force, so that the cold water comes into more comprehensive contact with the workpiece and milling cutter 2, improves the cooling quality of the workpiece and milling cutter 2, and avoids damage caused by excessive temperature of the workpiece and milling cutter 2, which would affect the normal use of the workpiece or milling cutter 2. This method is highly practical. Example 3:

[0040] Based on Embodiment 1, a preferred embodiment of the parallel-structured dual-spindle milling and turning machine tool provided by the present invention is, for example... Figures 1 to 11As shown: A recycling mechanism 6 is provided at the bottom of the processing chamber 1. The recycling mechanism 6 includes a recycling box 601, which is fixedly installed at the bottom of the processing chamber 1. A second water pump 602 is fixedly installed on the bottom inner wall of the recycling box 601. The input end of the second water pump 602 is connected to a second water suction pipe, and the output end of the second water pump 602 is connected to a second water guide pipe 603. The second water guide pipe 603 is fixedly installed through the back of the recycling box 601 and is connected to a water tank 501. A leak 604 is provided at the bottom of the processing chamber 1 and the top of the recycling box 601. A filter screen 605 is slidably connected to the inner wall of the leak 604. The filter screen 605 is equipped with a baffle 606, and the top surface of the baffle 606 is in contact with the filter screen 605. The filter screen 605 is adapted to the outlet 604. There are four baffles 606. By setting the baffles 606, the filter screen 605 can be supported and limited. A U-shaped support frame 607 is fixedly installed at the bottom of the filter screen 605. A vibrator 608 is fixedly installed on the inner wall of the U-shaped support frame 607. The vibrator 608 is in contact with the bottom surface of the filter screen 605. The filter screen 605 can filter the used water and prevent debris and foreign objects from affecting the normal operation of the water pump 602.

[0041] Used water flows into the inlet 604, then passes through the filter screen 605 in the inlet 604 before entering the recycling tank 601. The vibrator 608 is activated, causing the filter screen 605 to vibrate, preventing filtered debris and impurities from clogging the filter screen 605 and affecting its filtration efficiency. The second water pump 602 is activated, drawing the recycled water from the recycling tank 601 through the suction pipe 602, and then transporting it back to the water tank 501 through the second water guide pipe 603 for recycling. This mechanism allows for water recycling, reducing water waste and improving the environmental friendliness of the machine tool. Furthermore, the vibrator 608 ensures that the filter screen 605 vibrates, preventing filtered debris and impurities from clogging the filter screen 605 and affecting its filtration efficiency. The structure is simple and highly practical.
