Description

Technical Field

[0001] This invention relates to the field of composite CNC machine tool technology, specifically to a fully automatic multi-process synchronous machining composite CNC machine tool. Background Technology

[0002] A composite machine tool, also known as a composite machining tool, is a machining equipment based on CNC machine tools that integrates multiple processes such as turning, milling, drilling, and grinding into one unit. This equipment improves machining accuracy and efficiency by reducing the number of repeated workpiece clamping operations and is mainly used for machining complex parts in the aerospace, automotive, and mold industries.

[0003] In conventional milling operations, due to the limitations of the relative posture between the tool spindle and the workpiece, a single clamping often only allows for milling operations on a single surface or a specific orientation of the workpiece. After all operations on that surface are completed, the operator must release the workpiece clamp, manually flip or readjust the fixture, recalibrate the workpiece's clamping posture, and then re-tighten it before proceeding with milling operations on the other side. This sequential, multi-clamping machining method not only significantly increases auxiliary time and repetitive labor but also introduces uncontrollable positioning error accumulation due to repeated clamping, significantly reducing the overall form and position accuracy of the workpiece and production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic multi-process synchronous machining composite CNC machine tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic multi-process synchronous machining composite CNC machine tool, comprising: A base, the top of which is provided with a processing table; A control cylinder is fixed to the top of the processing table.

A synchronous machining device is installed above the base. The synchronous machining device consists of three sets of milling fixtures, which are used for synchronous multi-face milling. The milling fixture includes: a frame, a drive motor fixed to the top of the frame, and the output shaft of the drive motor fixed to a drive lead screw; A milling motor is fixed to a slide plate by bolts. A milling cutter head is fixed to the output shaft of the milling motor. A lead screw and slider are provided on the slide plate. The drive lead screw is connected to the lead screw and slider. A guide rod is fixed to the inside of the frame and passes through the slide plate and is slidably connected to the slide plate.

[0006] According to the above technical solution, a fixed seat is fixed above the base, and a sliding groove is opened on the top of the fixed seat. A support is slidably installed in the sliding groove on the top of the fixed seat. An electric push rod one is fixed on the top of the fixed seat.

An electric push rod two is rotatably installed on the inner side of the support. The output shaft of the electric push rod two is hinged to the frame.

[0007] According to the above technical solution, a servo motor is fixed to the top of the base, and the output shaft of the servo motor is fixed to the bottom of the processing table. The servo motor is used to drive the processing table to rotate and adjust at a small angle. A disc is rotatably installed below the processing table, and the bottom of the disc is fixed to the outer wall of the fixed base.

[0008] According to the above technical solution, a chip collection device is provided on the processing table and the base, and the chip collection device is used to collect the chips generated during milling; A tilting device for assisting in debris removal is provided below the processing table and on the chip suction device.

[0009] According to the above technical solution, the chip suction device includes: a chip suction cover, which passes through the processing table and is fixedly connected to the processing table, and an air suction pump is fixed on the top of the base; The suction coil is connected at one end to the suction pump and at the other end to the dust collection hood. A filter screen is installed on the inner wall of the dust collection hood, and the filter screen is located at the connection between the air intake coil and the dust collection hood.

[0010] According to the above technical solution, the bottom of the dust collection hood is open, and a bottom support plate is hinged to the bottom of the dust collection hood. An electromagnet is fixed to the top of the bottom support plate, and the inner side of the bottom support plate is inclined.

[0011] According to the above technical solution, the tilting device includes: a push-button switch, which passes through and is fixed to the processing table, and is electrically connected to an electromagnet; A collection rack is provided below the processing table and is used to collect debris poured out by the bottom receiving plate.

[0012] According to the above technical solution, a fixed rail is fixed to the bottom of the processing table, the fixed rail is inserted into the collection rack, and a magnet is fixed to the top of the collection rack.

[0013] Compared with the prior art, the present invention provides a fully automatic multi-process synchronous machining composite CNC machine tool, which has the following beneficial effects: 1. This invention utilizes a synchronized machining device. A drive motor rotates a lead screw, and under the linear guidance and constraint of a guide rod, a sliding plate moves the lead screw slider smoothly vertically. A milling motor drives the milling cutter head to rotate at high speed, performing milling on the workpiece on the machining table. Due to the lead screw drive structure, high displacement accuracy and strong load-bearing capacity are achieved, ensuring the stability of the milling process and the accuracy of the machining dimensions. Three sets of milling fixtures are spatially distributed, simultaneously milling different surfaces of the workpiece, realizing multi-face synchronous machining in a single clamping, significantly shortening auxiliary time and greatly improving production efficiency.

[0014] 2. This invention utilizes a synchronized processing device. An electric push rod drives a support to move laterally along a groove on the top of a fixed base, thereby synchronously adjusting the processing position of the machine frame, the milling motor mounted on it, and the milling cutter head to meet the processing requirements of workpieces of different sizes or different milling positions. When the electric push rod extends or retracts, it pushes the machine frame to swing around its hinge point with the support, achieving flexible adjustment of the milling angle. This angle adjustment mechanism allows the milling cutter head to adapt to milling operations with different angle characteristics, such as inclined planes and chamfers, expanding the machine tool's technological applicability.

[0015] 3. This invention incorporates a servo motor and a disc. The disc assists the base in supporting the fixed seat, increasing the load-bearing area and ensuring the stability of the fixed seat during processing. The disc is rotatably connected to the processing table, ensuring the disc remains stationary while the processing table rotates, thus not affecting the normal rotation of the processing table. The servo motor drives the processing table to rotate precisely at small angles, allowing for fine-tuning of the circumferential angle of the workpiece clamped at the top of the processing table. This assists the milling fixture in completing multi-faceted machining of the workpiece's side profile and complex contour surfaces, improving the continuity and consistency of multi-faceted machining.

[0016] 4. This invention features a chip-collecting device with the opening of the chip-collecting hood facing the center of the machining table, close to the cutting location, which facilitates the immediate capture of flying chips. After starting the suction pump, a negative pressure suction airflow is formed through the suction coil and the chip-collecting hood, efficiently drawing the milling chips into the hood. A filter screen is used to block chips, preventing them from entering the suction pump through the suction coil with the airflow, causing impeller jamming or motor damage, and ensuring that the chips are temporarily stored in the chip-collecting hood. The spiral-shaped suction coil made of rubber has good flexibility and extensibility. It can elastically deform when the processing table rotates slightly, which not only meets the displacement compensation required for the rotation of the processing table, but also does not affect the smooth flow of air, and can avoid fatigue damage to the pipeline due to repeated stretching. When the electromagnet at the top of the bottom receiving plate is energized, it attracts to the bottom of the chip suction hood, keeping the bottom receiving plate in close contact with the bottom of the chip suction hood, forming a closed temporary storage cavity. This allows for reliable reception and temporary storage of the chips sucked into the chip suction hood, preventing the chips from scattering during processing.

[0017] 5. This invention, through the inclusion of a chip-collecting device and a tilting device, controls the cylinder to move the fixture closer to the center of the machining table to clamp the workpiece. Simultaneously, the fixture releases the pressure on the push-button switch, activating the power supply circuit to the electromagnet. The electromagnet generates magnetic force to attract the bottom of the chip-collecting hood, driving the bottom receiving plate to swing upwards around its hinge point with the hood to a closed position. This effectively collects and temporarily stores the chips generated during machining inside the hood. After machining is completed, the control cylinder drives the fixture to reset. When the fixture returns to its initial position and the push-button switch is pressed again, the power supply circuit to the electromagnet is disconnected, and the magnetic force disappears. The bottom receiving plate swings downwards and opens under its own gravity around the hinge point. The debris accumulated on its top automatically slides down the preset inclined surface into the collection rack for centralized collection, realizing the automation of debris collection and discharge without manual intervention. This effectively prevents debris from continuously accumulating in the dust collection hood and the bottom receiving plate, avoiding blockage of the connection between the suction coil and the dust collection hood due to excessive debris accumulation, and ensuring the long-term stable operation of the debris collection function.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-6 One embodiment of the present invention is: a fully automatic multi-process synchronous machining composite CNC machine tool, comprising: Base 1, with a processing table 11 on top; A control cylinder 12 is fixed to the top of the processing table 11. A clamp 13 is fixed to the output end of the control cylinder 12. The control cylinder 12 is used to drive the clamp 13 to move and clamp the workpiece placed on the top of the processing table 11. The synchronous machining device is located above the base 1. The synchronous machining device consists of three sets of milling fixtures 2, which are used for synchronous multi-face milling. Among them, the milling fixture 2 includes a frame 21, a milling motor 24, a guide rod 27, and a fixed base 28; A drive motor 22 is fixed to the top of the frame 21, and the output shaft of the drive motor 22 is fixed to the drive screw 23. A milling motor 24 is fixed to the slide plate 25 by bolts, and a milling cutter head 26 is fixed to the output shaft of the milling motor 24. A screw-slider is provided on the slide plate 25, and the drive screw 23 is connected to the screw-slider. A guide rod 27 is fixed to the inside of the frame 21, passes through the slide plate 25, and is slidably connected to the slide plate 25. During operation, the drive motor 22 drives the drive screw 23 to rotate. Under the linear guidance and constraint of the guide rod 27, the slide plate 25 drives the screw-slider to move smoothly in the vertical direction. The milling motor 24 drives the milling cutter head 26 to rotate at high speed to perform milling on the workpiece on the machining table 11. Due to the use of a screw drive structure, the displacement accuracy is high and the load-bearing capacity is strong, which can ensure the stability of the milling process and the accuracy of the machining dimensions. The three sets of milling fixtures are arranged in a spatial layout, and simultaneously perform milling operations on different surfaces of the workpiece, realizing multi-face synchronous processing in a single clamping, greatly shortening auxiliary time and significantly improving production efficiency.

[0022] The fixed base 28 is fixedly installed above the base 1. A groove is provided on the top of the fixed base 28, and a support 29 is slidably installed within this groove. An electric push rod 210 is fixed to the top of the fixed base 28, and its output shaft is fixed to the support 29. The end of the support 29 away from the fixed base 28 is hinged to the frame 21. An electric push rod 211 is rotatably installed on the inner side of the support 29, and its output shaft is hinged to the frame 21. The electric push rod 210 drives the support 29 to move laterally along the groove on the top of the fixed base 28, thereby synchronously adjusting the machining position of the frame 21 and the milling motor 24 and milling cutter head 26 mounted on it to meet the machining requirements of workpieces of different sizes or different milling positions. When the electric push rod 211 extends or retracts, it pushes the frame 21 to swing around its hinge point with the support 29, achieving flexible adjustment of the milling angle. This angle adjustment mechanism allows the milling cutter head 26 to adapt to milling operations with different angle characteristics such as inclined planes and chamfers, thus expanding the range of applicable processes of the machine tool.

[0023] A servo motor 5 is fixed to the top of the base 1. The output shaft of the servo motor 5 is fixed to the bottom of the machining table 11. The servo motor 5 is used to drive the machining table 11 to rotate and adjust at small angles. A disc 6 is rotatably mounted below the machining table 11. The bottom of the disc 6 is fixed to the outer wall of the fixed seat 28. The disc 6 assists the base 1 in providing support for the fixed seat 28, increasing the load-bearing area and ensuring the stability of the fixed seat 28 during processing. The disc 6 is rotatably connected to the machining table 11. When the machining table 11 rotates, the disc 6 remains stationary and does not affect the normal rotation of the machining table 11. By driving the machining table 11 to rotate precisely at small angles through the servo motor 5, the circumferential angle of the workpiece clamped on the top of the machining table 11 can be finely adjusted, assisting the milling fixture 2 in completing multi-face machining of the workpiece's side profile and complex contour surfaces, improving the continuity and consistency of multi-face machining.

[0024] In this embodiment, the workpiece to be processed is placed on top of the processing table 11. The control cylinder 12 is activated to move the fixture 13 to clamp the workpiece. After clamping, the electric push rod 210 drives the support 29 to move laterally along the top slide groove of the fixed base 28, thereby driving the frame 21 and the milling motor 24 and milling cutter 26 mounted on it to adjust their processing positions synchronously. The drive motor 22 drives the drive screw 23 to rotate. Under the linear guidance and constraint of the guide rod 27, the slide plate 25 drives the screw slider to move smoothly in the vertical direction. The milling motor 24 drives the milling cutter 26 to rotate at high speed to perform milling processing on the workpiece on the processing table 11.

[0025] At the same time, the servo motor 5 drives the machining table 11 to rotate precisely at a small angle, which can finely adjust the circumferential angle of the workpiece clamped on the top of the machining table 11, and assist the milling fixture 2 in completing the multi-face machining of the workpiece's side profile and complex contour surface.

[0026] Please see Figures 1-6 Based on the above embodiments, in another embodiment of the present invention, a chip suction device 3 is provided on the processing table 11 and the base 1, and the chip suction device 3 is used to collect the chips generated during milling. A tilting device 4 for auxiliary chip cleaning is installed below the machining table 11 and on the chip suction device 3. The chip suction device 3 collects chips generated during milling in real time, effectively suppressing chip splashing into the surrounding environment, maintaining the cleanliness of the machining area, and reducing the potential harm of chips to the moving parts of the machine tool. After each machining cycle, the tilting device 4 automatically discharges the chips temporarily stored in the chip suction device 3, preventing excessive chip accumulation from causing blockage or reduced collection capacity, ensuring a continuous and stable chip collection effect, and facilitating centralized cleaning and recycling.

[0027] The chip suction device 3 includes: a chip suction hood 31, a suction coil 33, and a filter screen 34; The chip suction hood 31 passes through and is fixedly connected to the machining table 11. An air suction pump 32 is fixed to the top of the base 1. One end of the air suction coil 33 is connected to the air suction pump 32, and the other end is connected to the chip suction hood 31. A filter screen 34 is installed on the inner wall of the chip suction hood 31, positioned at the connection point between the air suction coil 33 and the chip suction hood 31. The opening of the chip suction hood 31 faces the center area of ​​the machining table 11, close to the cutting location, which facilitates the immediate capture of flying chips. After the air suction pump 32 is started, a negative pressure suction airflow is formed through the air suction coil 33 and the chip suction hood 31, efficiently drawing the milling chips into the chip suction hood 31. The filter screen 34 is used to block chips, preventing them from entering the air suction pump 32 through the air suction coil 33 with the airflow, causing impeller jamming or motor damage, ensuring that the chips are temporarily stored inside the chip suction hood 31. The spiral-shaped suction coil 33 made of rubber has good flexibility and extensibility. When the processing table 11 rotates slightly, it can elastically deform accordingly, which not only meets the displacement compensation required for the rotation of the processing table 11, but also does not affect the smooth flow of air, and can avoid fatigue damage to the pipeline due to repeated stretching.

[0028] The bottom of the chip suction hood 31 is open, and a bottom receiving plate 35 is hinged to the bottom of the chip suction hood 31. An electromagnet 36 is fixed to the top of the bottom receiving plate 35. The inner side of the bottom receiving plate 35 is inclined. When the electromagnet 36 at the top of the bottom receiving plate 35 is energized, it attracts to the bottom of the chip suction hood 31, so that the bottom receiving plate 35 is kept in close contact with the bottom of the chip suction hood 31, forming a closed temporary storage cavity. This allows for reliable reception and temporary storage of the chips sucked into the chip suction hood 31, preventing the chips from scattering during processing.

[0029] The tilting device 4 includes: a push-button switch 41, which passes through and is fixed to the processing table 11, and is electrically connected to the electromagnet 36. A collection rack 42 is positioned below the processing table 11. The collection rack 42 collects debris poured from the bottom receiving plate 35. When the control cylinder 12 moves the clamp 13 closer to the center of the processing table 11 to clamp the workpiece, the clamp 13 releases the pressure on the push-button switch 41, activating the power supply circuit of the electromagnet 36. The electromagnet 36 generates magnetic force to attract the bottom of the chip suction cover 31, driving the bottom receiving plate 35 to swing upwards to a closed position around its hinge point with the chip suction cover 31, effectively collecting and temporarily storing the debris generated during processing inside the chip suction cover 31. After processing is completed, the control cylinder 12 drives the clamp 13 to reset. When the clamp 13 moves back to its initial position and presses the push-button switch 41, the power supply circuit of the electromagnet 36 is disconnected, and the magnetic force disappears. The bottom receiving plate 35 swings downwards and opens under its own gravity around the hinge point, and the debris accumulated on its top automatically slides down the preset inclined surface into the collection rack 42 for centralized collection. This design automates debris collection and discharge without manual intervention, effectively preventing debris from continuously accumulating in the dust collection hood 31 and the bottom receiving plate 35, avoiding blockage of the connection between the suction coil 33 and the dust collection hood 31 due to excessive debris accumulation, and ensuring long-term stable operation of the debris collection function.

[0030] A fixed rail 43 is fixed to the bottom of the processing table 11. The fixed rail 43 is plugged into the collection rack 42. A magnet 44 is fixed to the top of the collection rack 42. The collection rack 42 is installed on the fixed rail 43 by plugging in. The structure is simple and easy to disassemble and assemble, making it convenient for workers to remove the collection rack 42 regularly to empty debris or for cleaning and maintenance. The magnet 44 is attracted to the fixed rail 43 when the collection rack 42 is installed in place, providing auxiliary fixing force to prevent the collection rack 42 from loosening or shifting due to vibration during machine operation, ensuring the stability of the collection rack 42 during operation.

[0031] In this embodiment, during the clamping process, when the fixture 13 moves to clamp the device, the fixture 13 releases the pressure on the push-button switch 41, activating the power supply circuit of the electromagnet 36. The electromagnet 36 generates magnetic force to attract the bottom of the chip suction cover 31, driving the bottom support plate 35 to swing upwards around its hinge point with the chip suction cover 31 to the closed position. During the machining process, the suction pump 32 operates, forming a negative pressure suction airflow through the suction coil 33 and the chip suction cover 31, efficiently drawing the milling debris into the chip suction cover 31. The filter screen 34 is used to block debris, preventing it from entering the suction pump 32 through the suction coil 33 with the airflow, causing impeller jamming or motor damage.

[0032] After processing is completed, the control cylinder 12 drives the clamp 13 to reset. When the clamp 13 moves back to the initial position and the push-button switch 41 is pressed, the power supply circuit of the electromagnet 36 is disconnected, and the magnetic force disappears. The bottom receiving plate 35 swings downward around the hinge point under its own gravity and opens. The debris accumulated on its top automatically slides down the preset inclined surface into the collection rack 42 for centralized collection.

[0033] When staff need to empty the debris from the collection rack 42, they can simply pull out the collection rack 42 to empty it and then reconnect it to the fixed rail 43.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
