Description

Technical Field

[0001] This application relates to the technical field of milling machines, and in particular to a horizontal and vertical dual-purpose gantry milling machine with vertical turning function. Background Technology

[0002] In heavy industries such as energy, aerospace, and shipbuilding, the processing of large parts (such as generator rotors, turbine housings, and large molds) usually requires multiple processes such as milling and turning.

[0003] Milling involves rotating the cutting tool and feeding the workpiece, and can machine planes, grooves, curved surfaces, and complex cavities. Turning involves rotating the workpiece and feeding the cutting tool, and is mainly used to machine rotating bodies, such as shafts, discs, and sleeves. Traditional processes involve repeatedly transferring and clamping parts between dedicated gantry milling machines and large vertical lathes.

[0004] In actual processing, operators need to collaborate between different machine tools, and multiple clamping and positioning of the workpiece consumes a lot of time, which has the drawback of affecting production efficiency. Summary of the Invention

[0005] In order to improve production efficiency and workpiece machining accuracy, this application provides a horizontal and vertical dual-purpose gantry milling machine with vertical lathe function.

[0006] The technical solution provided in this application for a horizontal and vertical dual-purpose gantry milling machine with vertical turning function is as follows:

[0007] A horizontal and vertical gantry milling machine with vertical turning function includes a machine tool, on which a gantry frame is mounted and spans across the machine tool; a milling assembly for workpiece milling is provided on one side of the gantry frame, and a turning assembly for workpiece turning is provided on the other side; a base is slidably mounted on the machine tool, sliding along the length of the machine tool, and a turntable is rotatably mounted on the base with its rotation axis rotating in the vertical direction, the turntable rotating relative to the base; multiple sliding grooves are formed on the top surface of the turntable, all of which are radially distributed with the center of the turntable as the center, and multiple clamping blocks are detachably connected to the turntable, the bottom ends of which are slidably mounted in the sliding grooves and slide along the length of the sliding grooves.

[0008] By adopting the above technical solution, milling and turning functions are integrated into the same machine tool. The workpiece is stably clamped by the clamping blocks in the radial slide grooves on the top of the turntable. After clamping, it can slide with the base to switch to the milling component or turning component station. The turntable rotates to meet the workpiece rotation requirements during turning. There is no need to transfer and clamp between different equipment, which greatly reduces auxiliary time and avoids the cumulative error caused by multiple positioning, thus significantly improving production efficiency and machining accuracy.

[0009] Optionally, the gantry frame is provided with a bidirectional sliding assembly, which includes a vertical slide rail and a horizontal slide rail. The vertical slide rail is fixed to the gantry frame in the vertical direction, and the horizontal slide rail is horizontally set and slidably set on the vertical slide rail. The horizontal slide rail slides relative to the vertical slide rail in the vertical direction, and the length direction of the horizontal slide rail is perpendicular to the length direction of the machine tool. Two sets of bidirectional sliding assemblies are provided and symmetrically distributed on both sides of the gantry frame. The two sets of symmetrically set bidirectional sliding assemblies are used to drive the turning assembly and the milling assembly to perform bidirectional displacement.

[0010] By adopting the above technical solution, the two sets of bidirectional sliding components provide the milling component and the turning component with bidirectional displacement freedom in the horizontal and vertical directions, respectively. The lifting and lowering movement of the horizontal slide rail along the vertical slide rail can adapt to workpieces of different heights, realize precise control of the processing position, and the symmetrical structure design improves the stability of the machine tool operation and adapts to the multi-directional processing needs of large parts.

[0011] Optionally, the milling assembly includes a milling head, a milling base, and a swing base. The milling head is rotatably mounted on the milling base and rotates relative to the milling base. The milling base is rotatably mounted on the swing base with its rotation axis set in the horizontal direction. The swing base is slidably mounted on a corresponding horizontal slide rail and slides along the length of the horizontal slide rail.

[0012] By adopting the above technical solution, the milling head rotates to realize the rotation action of the milling tool. The rotation of the milling base along the horizontal axis can adjust the machining angle of the milling head. Combined with the sliding of the swing base along the transverse slide rail, the milling assembly can flexibly adapt to various machining needs such as planes, grooves, curved surfaces and complex cavities, thereby improving the milling flexibility and machining range of the machine tool. Multi-feature machining can be completed without changing to special milling equipment.

[0013] Optionally, the turning assembly includes a cutting tool and a vertical carriage. The vertical carriage is slidably mounted on a corresponding horizontal slide rail and slides along the length of the horizontal slide rail. The cutting tool is slidably mounted on the vertical carriage and slides in the vertical direction.

[0014] By adopting the above technical solution, the sliding of the vertical lathe slide along the transverse slide rail and the vertical sliding of the cutting tool along the slide form a two-dimensional feed system. Combined with the rotation of the workpiece driven by the turntable, the tool feed action during turning is accurately realized. It can efficiently process rotating parts such as shafts, discs, and sleeves, and the feed path is highly controllable, ensuring the accuracy and smoothness of the turned surface.

[0015] Optionally, the machine tool is equipped with a drive assembly, which includes a drive motor, a drive slide rail, and a drive screw. The drive screw passes through the base and is rotatably mounted on the machine tool. The drive motor is fixed on the machine tool, and its output end is fixed to one end of the drive screw. The drive slide rail is arranged along the length of the machine tool and parallel to the drive screw. The base is slidably mounted on the drive slide rail. Corrugated covers are provided on both sides of the base. One end of the corrugated cover is fixed to the base, and the other end is fixed to the corresponding end of the machine tool. The corrugated covers cover the drive assembly.

[0016] By adopting the above technical solution, the drive motor drives the drive screw to rotate, and the drive base slides stably along the drive slide rail, realizing the precise switching of the workpiece between milling and turning stations. The transmission accuracy is high and the operation is smooth. The corrugated cover slides and expands with the base, which can effectively isolate machining chips and prevent dust or rust from accumulating inside the drive components. At the same time, its flexible structure does not affect the movement stroke of the base, thus improving the service life and reliability of the drive system.

[0017] Optionally, the corrugated cover has a raised center, and an air pipe is fixed in the center of the corrugated cover. The air pipe is arranged along the length of the machine tool and includes a fixed section and a folded section. An air inlet is provided on the base, and a first one-way valve is provided at the air inlet to allow air to enter the air inlet. One end of the fixed section is connected to the end of the air inlet away from the first one-way valve, and the other end is connected to the folded section. The folded section itself has compression and tension properties. An air outlet is provided on the fixed section, and a second one-way valve is provided at the air outlet to allow air to be ejected from the fixed section.

[0018] By adopting the above technical solution, when the base slides, it drives the corrugated cover to extend and retract. The air pipe in the raised part of the corrugated cover is stretched or compressed synchronously with the corrugated cover. When stretched, the volume of the air pipe increases and air is drawn in through the first one-way valve. When compressed, the volume decreases and air is ejected from the air outlet through the second one-way valve. The airflow is generated by the movement of the machine tool itself. The ejected airflow can sweep the surface of the corrugated cover, reduce the accumulation of debris, and eliminate the need for an additional air pump, thereby reducing the energy consumption and manufacturing cost of the equipment.

[0019] Optionally, a platform is provided between the turntable and the base. The platform is annular and has an annular air chamber inside. A blade, a spring, and an air storage device are provided on the platform. A one-way air inlet valve that only allows air to enter the air chamber from the outside is fixed on the outer wall of the platform. The air storage device is elastic and its interior is connected to the interior of the air chamber. A one-way air storage valve that only allows gas from the air chamber to enter the air storage device is provided between the air storage device and the air chamber. An air outlet pipe is connected to the air storage device. A nozzle is provided at the end of the air outlet pipe. The nozzle penetrates to the center of the top surface of the turntable for purging the slide groove. A normally closed pressure relief valve that is kept closed by centrifugal force is provided on the air outlet pipe. The blade is slidably mounted on the platform and slides radially along the platform. One end of the blade penetrates the inner wall of the platform and is fixed to one end of the spring. The end of the spring away from the blade is fixed to the inner wall of the platform. The spring is horizontally positioned and located in the air chamber. Multiple blades are provided. Adjacent blades are spaced apart circumferentially along the inner wall of the platform. The number of springs corresponds to the number of blades.

[0020] By adopting the above technical solution, when the turntable rotates, it drives the blades to rotate synchronously. The centrifugal force causes the blades to slide radially and compress the spring, squeezing the air in the air chamber. The high-pressure air enters the air storage component for storage through the one-way air storage valve, and external air is replenished into the air chamber through the one-way air intake valve. After the turntable stops, the centrifugal force disappears, the pressure relief valve opens, and the high-pressure gas in the air storage component is sprayed out from the nozzle through the air outlet pipe, accurately blowing away the debris in the turntable's sliding groove. The kinetic energy of the workpiece rotation is converted into air storage power to achieve automatic cleaning, avoiding the debris from affecting the sliding accuracy of the clamping block. Moreover, the purely mechanical structure does not require electrical control, resulting in higher reliability.

[0021] Optionally, the nozzle is rotatably connected to the air outlet pipe and fixedly connected to the turntable, and the number of air outlet holes of the nozzle corresponds to the number of slide grooves.

[0022] By adopting the above technical solution, the nozzle rotates synchronously with the turntable, and its air outlet corresponds one-to-one with the radial chute, thus achieving precise purging of the chute.

[0023] Optionally, a seal is provided between the blade and the pad.

[0024] By adopting the above technical solution, the seal can effectively fill the gap between the blade and the pad, reduce gas leakage in the air chamber during the blade compression process, and improve air compression efficiency and the inflation speed of the air storage device.

[0025] Optionally, the machine tool is provided with a debris groove, which is opened along the length of the machine tool, and the debris groove is arranged adjacent to the corrugated cover.

[0026] By adopting the above technical solution, the debris around the corrugated cover and on the surface of the machine tool can be swept away by the airflow from the air pipe and fall into the adjacent debris tank. This prevents the debris from scattering everywhere and polluting the processing environment or entering other moving parts of the machine tool, making it easier to clean up later. At the same time, it reduces the impact of debris on the accuracy of the machine tool and improves the convenience of equipment operation and maintenance.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. It integrates milling and turning functions, eliminating the need for workpiece transfer and clamping between different machine tools, significantly reducing auxiliary processing time, avoiding cumulative errors caused by multiple positioning, and significantly improving production efficiency and machining accuracy, thus adapting to the multi-process machining needs of large heavy industrial parts.

[0029] 2. The design features a dual self-cleaning structure. The rotational energy of the turntable drives the air chamber to store air, and the sliding of the base drives the air pipe to extend and release air. Without the need for an additional air pump or electrical control, it can automatically clean the slide and the machine tool surface of debris, which reduces equipment energy consumption and manufacturing costs, and ensures the sliding accuracy and service life of moving parts.

[0030] 3. The bidirectional sliding assembly is adapted to the milling and turning assemblies, giving the machine tool a multi-directional and multi-angle machining freedom. It can flexibly adapt to various machining needs such as planes, grooves, curved surfaces, complex cavities and rotating bodies, thereby improving the machining flexibility and applicability of the equipment.

[0038] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0039] This application discloses a horizontal and vertical dual-purpose gantry milling machine with vertical turning function, which is mainly used in heavy industries such as energy, aerospace, and shipbuilding. It is used to solve the problems of cumbersome transfer and clamping, low production efficiency, and easy impact on machining accuracy caused by the separation of milling and turning processes in the processing of large parts.

[0040] refer to Figure 1 and Figure 2 A horizontal-vertical dual-purpose gantry milling machine with vertical turning function includes a machine tool 1. A gantry frame 11 is mounted on the upper surface of the machine tool 1. The gantry frame 11 has a gantry-shaped structure that spans across the machine tool 1, providing mounting support for subsequent machining components. A milling component 2 for workpiece milling is provided on one side of the gantry frame 11, and a turning component 3 for workpiece turning is correspondingly provided on the other side. Through the symmetrical layout of single-sided milling and single-sided turning, the integration of two machining functions on the same machine tool is realized.

[0041] refer to Figure 2 and Figure 4 A base 12 is slidably mounted on the upper surface of the machine tool 1 along its length. The base 12 achieves stable sliding through a drive assembly 6. The drive assembly 6 includes a drive motor 61, a drive slide rail 62, and a drive screw 63. The drive screw 63 horizontally passes through the base 12 and is rotatably mounted on the machine tool 1 through a bearing. The drive motor 61 is fixed to the end of the machine tool 1 by bolts, and its output end is fixedly connected to one end of the drive screw 63 through a coupling. The drive slide rail 62 is set parallel to the drive screw 63 along the length of the machine tool 1. The bottom of the base 12 is slidably engaged with the drive slide rail 62 by a slider. Starting the drive motor 61 can drive the drive screw to rotate, thereby driving the base 12 to slide smoothly along the drive slide rail 62, realizing precise switching of the workpiece between the milling station and the turning station.

[0042] refer to Figure 1 , Figure 2 and Figure 3 Both sides of the base 12 are provided with corrugated covers 13. One end of the corrugated cover 13 is fixedly connected to the side of the base 12, and the other end is fixedly connected to the side wall of the corresponding end of the machine tool 1. The corrugated cover 13 covers the outside of the drive assembly 6. Its flexible structure can extend and retract with the sliding of the base 12, effectively isolating the debris and coolant generated during the processing, preventing dust accumulation, corrosion or jamming of debris inside the drive assembly 6, and ensuring the transmission accuracy and service life of the drive system.

[0043] refer to Figure 1 , Figure 2 and Figure 3 The corrugated cover 13 has a raised center, and an air pipe 14 is fixed to the raised part along the length of the machine tool 1. The air pipe 14 includes a fixed section 141 and a folded section 142. The folded section 142 is made of a flexible corrugated material and has compression and tension properties. An air inlet 121 is opened on the side of the base 12 and extends into it. A first one-way valve 122 is installed at the outer port of the air inlet 121. The first one-way valve 122 only allows external air to enter the air inlet 121 and prevents air from flowing out in the opposite direction. One end of the fixed section 141 of the air pipe 14 is sealed and connected to the end of the air inlet 121 away from the first one-way valve 122, and the other end is sealed and connected to one end of the folded section 142. The other end of the folded section 142 is fixed to the end side wall of the machine tool 1. Multiple air outlets are provided on the pipe wall of the fixed section 141. A second one-way valve 15 is installed at each air outlet. The second one-way valve 15 only allows air inside the air pipe 14 to be ejected from the air outlet and prevents external air from entering in the opposite direction.

[0044] refer to Figure 1 , Figure 2 and Figure 3 When the base 12 slides along the length of the machine tool 1, it will drive the corrugated cover 13 to extend and retract synchronously, thereby pulling the folded section 142 of the air pipe 14 to achieve stretching or compression: when the corrugated cover 13 and the folded section 142 of the air pipe 14 are stretched, the internal volume of the air pipe 14 increases to form a negative pressure, and external air is drawn into the air pipe 14 through the first one-way valve 122 and the air inlet 121; when the corrugated cover 13 and the folded section 142 of the air pipe 14 are compressed, the internal volume of the air pipe 14 decreases, and the air is squeezed and ejected from the air outlet through the second one-way valve 15. The ejected airflow can directly sweep the surface of the corrugated cover 13 and blow off the scattered debris. On one side of the corrugated cover 13, a debris groove 16 extending along its length is provided on the upper surface of the machine tool 1. The debris blown away by the airflow from the air pipe 14 can fall into the debris groove 16 in a concentrated manner, preventing the debris from scattering everywhere and polluting the processing environment or entering other moving parts of the machine tool 1, and making it convenient for subsequent operators to clean it up.

[0045] refer to Figure 1 A turntable 4 is rotatably mounted on the upper surface of the base 12. The rotation axis of the turntable 4 is set vertically and is rotatably connected to the base 12 through built-in bearings. It can rotate stably relative to the base 12 to meet the process requirements of workpiece rotation during turning. The top surface of the turntable 4 has multiple sliding grooves 41, all of which are radially and evenly distributed around the center of the turntable 4. Multiple clamping blocks 42 are detachably connected to the turntable 4 by bolts. The bottom end of the clamping block 42 is slidably engaged in the sliding groove 41 by a slider and can slide freely along the length of the sliding groove 41. The spacing between adjacent clamping blocks 42 can be adjusted according to the size of the workpiece to achieve stable clamping of large workpieces of different specifications. The detachable design facilitates the replacement and maintenance of the clamping blocks 42.

[0046] refer to Figure 1 and Figure 2 Two sets of symmetrically distributed bidirectional sliding components 5 are provided on the gantry frame 11. The two sets of bidirectional sliding components 5 are respectively set for the milling component 2 and the turning component 3, and are used to drive the two machining components to achieve bidirectional displacement. The bidirectional sliding component 5 includes a vertical slide rail 51 and a horizontal slide rail 52. The vertical slide rail 51 is fixed to the inner side of the column of the gantry frame 11 in the vertical direction by bolts. The horizontal slide rail 52 is horizontally set, and its end is slidably engaged with the vertical slide rail 51 by a slider. It can slide up and down relative to the vertical slide rail 51 in the vertical direction. The length direction of the horizontal slide rail 52 is perpendicular to the length direction of the machine tool 1, providing lateral displacement support for the machining components.

[0047] refer to Figure 1 The milling assembly 2 includes a milling head 21, a milling base 22, and a swing base 23. The milling head 21 is rotatably mounted on the milling base 22 via a rotating shaft and can rotate at high speed relative to the milling base 22 to realize the tool rotation action during milling. A motor is installed inside the milling base 22 to drive the milling head 21 to rotate. The milling base 22 is rotatably mounted on the swing base 23 via a horizontally set rotating shaft. The rotating shaft extends in a direction perpendicular to the length of the machine tool 1, which can drive the milling head 21 to adjust the machining angle. The swing base 23 is slidably mounted on a corresponding transverse slide rail 52 via a slider and slides along the length of the transverse slide rail 52 to adjust the transverse distance between the milling head 21 and the workpiece. Through the rotation of the milling head 21, the angle adjustment of the milling base 22, and the transverse sliding of the swing base 23, the milling assembly 2 can flexibly adapt to various milling requirements such as planes, grooves, curved surfaces, and complex cavities, improving the machining flexibility of the machine tool and completing multi-feature machining of workpieces without changing to dedicated milling equipment.

[0048] refer to Figure 2The turning assembly 3 includes a cutting tool 31 and a vertical slide 32. The vertical slide 32 is slidably mounted on a corresponding transverse slide rail 52, sliding horizontally along the length of the transverse slide rail 52. The cutting tool 31 is slidably mounted on the side of the vertical slide 32, with its sliding direction set vertically. This can be achieved by installing a cylinder, which is vertically fixed on the vertical slide 32. The piston end of the cylinder drives the cutting tool 31 to move vertically. The transverse sliding of the vertical slide 32 and the vertical sliding of the cutting tool 31 form a two-dimensional feed system. Combined with the rotation of the workpiece driven by the turntable 4, the tool feed action during turning can be accurately realized, efficiently machining rotating parts such as shafts, discs, and sleeves. Furthermore, the feed path is highly controllable, ensuring the machining accuracy and surface finish of the turned surface.

[0049] refer to Figure 1 , Figure 5 and Figure 6 An annular platform 7 is provided between the turntable 4 and the base 12. The platform 7 is fixed to the upper surface of the base 12 by bolts. The turntable 4 is rotatably mounted on the upper surface of the platform 7. An annular air chamber 71 is formed inside the platform 7, and the air chamber 71 is in a closed loop around the rotation axis of the turntable 4. A one-way air intake valve 72 is fixedly installed on the outer wall of the platform 7. One end of the one-way air intake valve 72 is connected to the outside, and the other end penetrates into the air chamber 71, allowing only outside air to enter the air chamber 71 and preventing the air inside the air chamber 71 from flowing out in the opposite direction. The platform 7 is also equipped with blades 73, springs 74, and air storage components 75. Multiple blades 73 are provided, with adjacent blades 73 evenly spaced circumferentially along the inner wall of the platform 7. The blades 73 slide radially along the inner wall of the platform 7, with one end penetrating into the air chamber 71 and the other end extending to the outer side of the inner wall of the platform 7. The end of the blade 73 inside the air chamber 71 is fixedly connected to one end of the spring 74. The end of the spring 74, horizontally positioned and away from the blade 73, is fixedly connected to the inner wall of the air chamber 71. The spring 74 is always in a naturally extended / retracted state, providing radial return force for the blades 73. A seal is provided at the sliding contact point between the blades 73 and the platform 7 (not shown in the figure). The seal is a wear-resistant rubber ring, which effectively fills the gap between the blades 73 and the platform 7, reducing gas leakage in the air chamber 71 during air compression and improving air compression efficiency and air storage speed.

[0050] refer to Figure 1 , Figure 5 and Figure 6The gas storage component 75 is a high-pressure airbag with elasticity, which is fixed on the upper surface of the pad 7 and located inside the air chamber 71. The interior of the gas storage component 75 is connected to the interior of the air chamber 71 through a pipe, and a one-way gas storage valve 76 is installed on the connecting pipe. The one-way gas storage valve 76 only allows the high-pressure air in the air chamber 71 to enter the gas storage component 75 for storage, and prohibits the air in the gas storage component 75 from flowing back to the air chamber 71. The top of the air storage unit 75 is connected to an air outlet pipe 8, which extends vertically upwards. Its end passes through the center of the top surface of the turntable 4 and is connected to a nozzle 81. The nozzle 81 is rotatably connected to the air outlet pipe 8 via a rotary joint, and the nozzle 81 is fixedly connected to the center of the top surface of the turntable 4, rotating synchronously with the turntable 4. Multiple air outlet holes are opened on the side wall of the nozzle 81, the number of which corresponds one-to-one with the number of slide grooves 41 on the turntable 4, and the orientation of the air outlet holes is consistent with the extension direction of the slide grooves 41, for precisely blowing away debris in the slide grooves 41. A normally closed pressure relief valve 82 is installed on the air outlet pipe 8. The normally closed pressure relief valve 82 is equipped with a centrifugal force sensing valve core. The centrifugal force generated when the turntable 4 rotates can keep the valve core in a closed state, sealing the air outlet pipe 8. When the turntable 4 stops rotating and the centrifugal force disappears, the valve core is reset under the action of the internal spring, opening the air outlet pipe 8.

[0051] refer to Figure 1 , Figure 5 and Figure 6 When the workpiece is clamped, and the turntable 4 rotates for turning or to provide auxiliary positioning for milling, the blade 73 rotates synchronously with the turntable 4. The centrifugal force generated by the rotation overcomes the elastic force of the spring 74, pushing the blade 73 to slide radially outward, thereby compressing the air inside the air chamber 71 and creating high pressure. The high-pressure air opens the one-way air storage valve 76 and continuously enters the air storage component 75 for storage. At the same time, external air continuously replenishes the air chamber 71 through the one-way air intake valve 72, ensuring the air pressure remains constant. Continuous air supply: When the turntable 4 stops rotating (during process switching or processing completion), the centrifugal force disappears, the valve core of the normally closed pressure relief valve 82 resets and opens, and the high-pressure air stored in the air storage component 75 is delivered to the nozzle 81 through the air outlet pipe 8, and sprayed out from the air outlet corresponding to the slide groove 41, realizing the purging of all slide grooves 41, thoroughly blowing the processing debris accumulated in the slide grooves 41 into the debris groove 16 of the machine tool 1, avoiding the debris from affecting the sliding accuracy of the clamping block 42, and ensuring the accuracy of subsequent clamping and processing. This structure uses the kinetic energy of the workpiece rotation to convert into air storage power, and the pure mechanical triggering does not require electrical control, resulting in higher reliability. Moreover, it does not require additional cleaning equipment, further improving the integration and practicality of the equipment.

[0052] In this embodiment, there are multiple ways to achieve the sliding of the vertical slide rail 51, the horizontal slide rail 52, the swing seat 23, and the vertical carriage slide 32. An electric cylinder can be used as the power source, or the base 12 can be slid as driven by the drive assembly 6. There are many implementation methods, which will not be elaborated upon in this embodiment. Additionally, there are many ways to drive the turntable 4 to rotate. A gear ring can be fixed to the outer wall of the turntable 4, and a motor can be fixed to the base 12. A gear is fixed to the output end of the motor, and the gear meshes with the gear ring to drive the turntable 4 to rotate. The specific implementation structure for driving the turntable to rotate is not shown in the figure.

[0053] The implementation principle of this application embodiment is as follows: Before processing, the position of the clamping block 42 on the turntable 4 is adjusted according to the workpiece size to securely clamp the workpiece on the turntable 4; the drive motor 61 is started, and the base 12 is driven to slide along the drive slide rail 62 through the drive screw 63 to move the workpiece to the corresponding station of the milling assembly 2 or the turning assembly 3. During milling, the vertical height and horizontal position of the milling assembly 2 are adjusted by the bidirectional sliding assembly 5, the milling head 21 rotates to achieve cutting, and the milling base 22 rotates to adjust the processing angle to complete the processing of features such as planes, grooves, and curved surfaces; during turning, the turntable 4 rotates to drive the workpiece to rotate, the bidirectional sliding assembly 5 adjusts the horizontal position of the turning assembly 3, and the vertical lathe slide 32 drives the cutting tool 31 to feed vertically to complete the machining of the rotating body. During processing, as the base 12 slides, it causes the corrugated cover 13 and the air pipe 14 to extend and retract, automatically drawing in and expelling air to blow away debris from the surface of the machine tool 1 and the area around the corrugated cover 13. The debris falls into the debris trough 16. When the turntable 4 rotates, the driving blades 73 compress the air in the air chamber 71, and the high-pressure air is stored in the air storage component 75. After the turntable 4 stops, the high-pressure air in the air storage component 75 is sprayed out through the nozzle 81 to clean the debris in the slide groove 41. The entire processing process does not require workpiece transfer, realizing the integration of milling and turning.
