[0022] 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.

[0023] Example 1 See also Figures 1-10 , the present invention provides the following technical solutions: A device for processing nickel-based alloy thin-walled parts based on turning and milling combination, comprising: Processing lathe 1; The base slide rail 2 is fixedly connected to the upper end of the processing lathe 1; A sliding gantry 3 is slidably connected to the upper end of the processing lathe 1; A transverse slide rail 4 is fixedly connected to one side end of the sliding gantry 3; A cutting tool 5 is slidably connected to one side end of the transverse slide rail 4; Cooling mechanism, the cooling mechanism includes a supporting slide rod 6, a supporting slider 7, a threaded sleeve 8, a cooling nozzle 9, a bidirectional screw 10 and a heat source sensor 11. The supporting slide rod 6 is fixedly connected to the lower end of the sliding gantry 3, the supporting slider 7 is slidably connected to the circumferential surface of the supporting slide rod 6, the threaded sleeve 8 is fixedly connected to the lower end of the supporting slider 7, the cooling nozzle 9 is rotatably connected to the lower end of the threaded sleeve 8 through a rotating shaft, the bidirectional screw 10 is threadedly connected in the threaded sleeve 8, and the heat source sensor 11 is fixedly connected to the lower end of the cooling nozzle 9.

[0024] In a specific embodiment of the present invention, the base slide rail 2 is fixedly connected to the upper end of the processing lathe 1, and is used to guide the sliding gantry 3 to move horizontally. The sliding gantry 3 can slide along the base slide rail 2, driving the horizontal slide rail 4 and the cutting tool 5 to feed. The horizontal slide rail 4 is fixed to one side of the sliding gantry 3, allowing the cutting tool 5 to slide and adjust the distance thereon. The cutting tool 5 performs turning or milling operations. The support slide bar 6 is used to support multiple groups of cooling nozzles 9. The support slider 7 is slidably connected to the support slide bar 6 for adjusting the position of the multiple groups of cooling nozzles 9, and the multiple groups of cooling nozzles 9 are all provided on the outer surface of the bidirectional screw 10 through the threaded sleeve 8, wherein the two groups of threaded sleeves 8 are respectively provided on the threads in different directions on both sides of the screw, and the other threaded sleeve 8 located in the center does not contact the threads and the heat source sensor 11 is also fixed on this cooling nozzle 9. The cooling nozzle The head 9 is connected to the lower end of the threaded sleeve 8 through a rotating shaft, and the spray angle can be adjusted. During processing, the nickel-based alloy thin-walled part to be processed is fixed in the fixture on the processing lathe 1, and the sliding gantry 3 drives the cutting tool 5 to move along the base slide rail 2. At the same time, the cutting tool 5 is precisely positioned along the transverse slide rail 4 to complete the turning and milling composite processing. The heat source sensor 11 monitors the temperature changes in the cutting area in real time. The control system starts the motor to drive the bidirectional screw 10 according to the data signal of the heat source sensor 11. The bidirectional screw 10 drives the threaded sleeve 8 to move, thereby adjusting the spacing between the cooling nozzles 9. The cooling nozzle 9 can flexibly adjust the spray angle through the rotating shaft to ensure that the coolant accurately covers the current cutting point. By dynamically adjusting the layout and angle of the cooling nozzle 9, the coolant can fully contact the high-temperature area, reduce the temperature of the cutting area, and reduce thermal deformation and tool wear.

[0025] For details, please refer to Figures 1-9 The lower end of the sliding gantry 3 is fixedly connected to a motor mounting frame 12 , a drive motor 13 is fixedly connected to the motor mounting frame 12 , and an output end of the drive motor 13 is fixed to one side end of the bidirectional screw 10 .

[0026] In this embodiment: when the heat source sensor 11 detects a high-temperature cutting area, the drive motor 13 in the start-up motor mounting bracket 12 is output and transmitted to the bidirectional screw 10 through a coupling or a gear set, and the multiple threaded sleeves 8 are limited by the supporting slide rod 6 and cannot rotate. Therefore, the bidirectional screw 10 rotates, driving the multiple threaded sleeves 8 to move relative to each other along the axial direction of the screw. After the nozzle spacing is adjusted, the coolant coverage range changes accordingly, and acts precisely on the cutting hot spot area.

[0027] For details, please refer to Figures 1-9 One side end of the transverse slide rail 4 is fixedly connected to a telescopic cylinder 14, the extended end of the telescopic cylinder 14 is fixedly connected to a steering slide rod 15, the circumferential surface of the steering slide rod 15 is slidably connected to a steering rod 16, and one side end of the cooling nozzle 9 is connected to the other side end of the steering rod 16 through a rotating shaft.

[0028] In this embodiment: the control system determines the angle that the cooling nozzle 9 should be adjusted according to the current cutting path and heat source distribution, and starts the telescopic cylinder 14. Its extended end pushes the steering slide 15 to move in the specified direction, and the steering slide 15 drives the steering rod 16 to move. Since one end of the steering rod 16 is connected to the cooling nozzle 9 through a rotating shaft, this displacement will cause the cooling nozzle 9 to rotate around the rotating shaft, and the nozzle angle will change accordingly, so that the coolant can be sprayed to the current cutting point more accurately.

[0029] For details, please refer to Figures 1-9 The upper end of the sliding gantry 3 is fixedly connected to a cooling water sprayer 17 , and one side end of the supporting slider 7 and one side end of the cooling water sprayer 17 are fixedly connected to a water spray pipe 18 .

[0030] In this embodiment: the cooling water sprayer 17 is installed at the upper end of the sliding gantry 3 and serves as the coolant supply main pipe. The coolant is pumped into the cooling water sprayer 17 from the external cooling system and then transported to each cooling nozzle 9 through the water spray pipe 18. The water spray pipe 18 ensures that the coolant is stably delivered to each nozzle, realizing automated closed-loop control of the entire process of cutting, temperature measurement, nozzle adjustment, and cooling liquid supply.

[0031] For details, please refer to Figures 1-9 The upper end of the processing lathe 1 is slidably connected with a fixed clamping block 19, and an electric clamping mechanism is arranged in the fixed clamping block 19 to fix the nickel-based alloy thin wall.

[0032] In this embodiment: the nickel-based alloy thin-walled part to be processed is placed between the fixed clamping blocks 19, the servo motor drives the screw transmission assembly to push the clamping jaws toward the center, and the pressure sensor monitors the clamping force in real time and feeds back to the control system. When the clamping force reaches the set value, the servo motor stops running and the clamping is completed. In this process, the clamping force can be adjusted according to the material and thickness of the different workpieces to avoid over-pressure deformation.

[0033] For details, please refer to Figures 1-9The upper end of the processing lathe 1 is slidably connected to a leveling test frame 20, and a telescopic slide 22 is provided at the lower end of the leveling test frame 20. A vertical slide rod 23 is slidably connected in the telescopic slide 22, and a connecting rod 24 is fixedly connected to the lower end of the vertical slide rod 23. A bump sensing wheel 29 is fixedly connected to the lower end of the connecting rod 24, and a pressure sensor 25 is fixedly connected in the vertical slide rod 23.

[0034] In this embodiment: the nickel-based alloy thin-walled part to be processed is placed between the fixed clamps 19, the leveling test frame 20 moves synchronously with the sliding gantry 3, and reaches the processing position before the cutting tool 5. The bump sensing wheel 29 contacts the workpiece surface under the action of gravity. When there is a bump on the workpiece surface, the bump sensing wheel 29 is lifted up, pushing the vertical slide bar 23 to slide upward. The pressure sensor 25 detects the pressure change and determines it as an abnormal bump area, and then replaces the workpiece to avoid the bump part from generating a large impact force on the tool, thereby protecting the blade.

[0035] For details, please refer to Figures 1-9 A contact slide 21 is provided on the upper inner wall of the telescopic slide 22, and a limit slide 26 is provided on the side inner wall of the contact slide 21. The limit slide 26 is slidably connected to the inductive contact slider 27. The inductive contact slider 27 is provided at the upper end of the sensing end of the pressure sensor 25. A reset spring 28 is fixedly connected to the upper end of the inductive contact slider 27 and the upper inner wall of the contact slide 21.

[0036] In this embodiment: the bump sensing wheel 29 contacts the workpiece surface before the cutting tool 5. If there is a tiny bump on the surface, the sensing wheel is compressed upward, pushing the connecting rod 24 and the vertical slide bar 23 to rise, and the vertical slide bar 23 drives the sensing contact slider 27 to slide upward along the limiting slide groove 26. The vertical slide bar 28 applies a thrust to the sensing contact slider 27, so that the vertical slide bar 23 drives the sensing contact slider 27 to slide upward along the limiting slide groove 26. The pressure sensor 25 detects the pressure change and determines it as an abnormal bump area. When the bump sensing wheel 29 leaves the bump area, the sensing contact slider 27 returns to its initial position under the action of the reset spring 28.

[0037] For details, please refer to Figures 1-9 A water storage tank 33 is provided in the processing lathe 1 , and a water outlet 30 is provided on the lower inner wall of the water storage tank 33 .

[0038] In this embodiment: the water tank 33 is opened inside the processing lathe 1, located below the processing area, and is used to receive the coolant flowing down from the processing area. The surface is provided with an inclined guide structure to facilitate liquid collection. The drain port 30 is opened on the lower inner wall of the water tank 33 and can be controlled to open and close to realize the circulation of the coolant.

[0039] For details, please refer to Figures 1-9The lower end of the processing lathe 1 is fixedly connected with a solid-liquid separator 31 , the water inlet of the solid-liquid separator 31 is arranged at the lower end of the drain 30 , and a magnetic filtering mechanism is provided in the solid-liquid separator 31 .

[0040] In this embodiment: the used coolant flows into the water storage tank 33 arranged inside the processing lathe 1 by gravity. The bottom of the water storage tank 33 is provided with an inclined diversion structure, and the liquid naturally flows to the drain 30. The coolant flows into the solid-liquid separator 31 located below the lathe through the drain 30. After the coolant enters the solid-liquid separator 31, it first passes through the magnetic filtering mechanism, and the magnetic metal impurities are adsorbed by the permanent magnet, and the non-metallic impurities are intercepted by the filter layer. The separated clean coolant flows into the collection chamber and returns to the cooling sprinkler 17 through the circulating water pipe 32 to achieve recycling.

[0041] For details, please refer to Figures 1-9 The output end of the solid-liquid separator 31 and the input end of the cooling water sprayer 17 are fixedly connected with a circulating water pipe 32.

[0042] In this embodiment, the purified coolant is transported to the cooling water sprayer 17 via the circulating water pipe 32, and the cooling water sprayer 17 supplies the coolant to the cooling nozzle 9 again, completing the closed-loop circulation of the coolant. The entire process does not require manual intervention and can achieve long-term continuous operation.

[0043] It should be noted that the cutting tool 5, cooling water sprayer 17, fixing clamp 19, pressure sensor 25 and solid-liquid separator 31 used in this solution are all existing technologies and will not be described in detail here.

The sliding gantry 3 can slide along the base slide rail 2, driving the horizontal slide rail 4 and the cutting tool 5 to feed. The horizontal slide rail 4 is fixed to one side of the sliding gantry 3, allowing the cutting tool 5 to slide and adjust the distance thereon. The cutting tool 5 performs turning or milling operations. The support slide bar 6 is used to support multiple groups of cooling nozzles 9.

During processing, the nickel-based alloy thin-walled part to be processed is fixed in the fixture on the processing lathe 1, and the sliding gantry 3 drives the cutting tool 5 to move along the base slide rail 2. At the same time, the cutting tool 5 is precisely positioned along the transverse slide rail 4 to complete the turning and milling composite processing.
