Description

Technical Field

[0001] This invention relates to the field of workpiece processing technology, specifically to a CNC and grinding integrated processing method and equipment. Background Technology

[0002] CNC machining, also known as computer-controlled milling, CNCCH, or numerical control machine tools, is a precision machining technology that uses computer digital control. The main equipment includes machining lathes, milling machines, boring and milling machines, etc. It is characterized by stable machining quality and high precision. This technology controls the movement of the machine tool through G-code programming, and automatically generates programs by reading CAD files with CAM software. Repetitive machining is handled by subroutines. By adding a grinding machine into the machine tool, milling and grinding are integrated to continuously complete CNC milling and grinding finishing. The process is seamless and does not require disassembly or changing machine tools for transportation.

[0003] During the switching of machining positions, the milling and grinding mechanisms are prone to large-scale deflection. When the tool is in a large-angle tilt state, the cutting force and grinding force will decompose into additional lateral components, causing spindle vibration and tool wobble, which degrades the surface machining quality of the workpiece. At the same time, the large-angle operation of the tool requires more space to be reserved inside the equipment, which restricts the structural layout. In addition, during the grinding process, machining debris is easily retained on the surface of the workpiece, which further affects the quality of the finished product. Summary of the Invention

[0004] The purpose of this invention is to provide a CNC and grinding integrated machining method and equipment to solve the problem that the machining effect is easily affected when the tool is in a large angle of inclination.

[0006] As a further embodiment of the present invention: the tilting limiter further includes four second annular sleeves installed at the bottom of the positioning seat. The four second annular sleeves are divided into two groups, and the two groups of second annular sleeves are symmetrically arranged along the transverse central axis of the positioning seat. Two second annular sleeves in each group are symmetrically arranged along the transverse central axis of the positioning seat. A first connecting ball shaft is provided on the inner side of the second annular sleeve. A piston rod is connected to the bottom of the first connecting ball shaft. A piston cylinder is sleeved on the outer side of the piston rod. A second connecting ball shaft is installed at the bottom end of the piston cylinder. A first annular sleeve is sleeved on the outer side of the second connecting ball shaft. A connecting pipe penetrating the partition is provided at the bottom of the first annular sleeve. A solenoid valve is installed at the bottom end of the connecting pipe. A guide pipe extending to the inside of the water tank is provided at one end of the solenoid valve. The connecting pipe is in communication with the water tank through the solenoid valve and the guide pipe. A guide hole penetrating the second connecting ball shaft is opened on the inner side of the second connecting ball shaft.

[0007] As a further aspect of the present invention: the angle between the bottom of the third movable frame and the top of the second movable frame is ninety degrees.

[0008] As a further embodiment of the present invention: the center line of the connecting plate is coaxial with the center line of the positioning seat.

[0009] As a further aspect of the present invention: the maximum moving distance of the piston rod relative to the piston cylinder is greater than the distance between the positioning seat and the partition plate.

[0010] As a further embodiment of the present invention: the inner wall diameter of the connecting pipe is larger than the outer wall diameter of the piston cylinder, and the diameter of the guide hole is larger than the inner wall diameter of the piston cylinder.

[0011] As a further embodiment of the present invention: the shifting collection component includes guide blocks installed on both sides of the bottom of the positioning seat, a slider is movably sleeved on the outer side of the guide block, a guide rod extending to the other side of the slider is inserted into one side of the slider, a first telescopic spring connected to the slider is provided at one end of the guide rod, a second telescopic spring connected to the guide block is provided on one side of the slider, and a rectangular frame located outside the positioning seat is connected to the other end of the guide rod, and a collection groove is provided at the top of the rectangular frame.

[0012] As a further embodiment of the present invention: the horizontal height of the top of the rectangular card frame is lower than the horizontal height of the top of the positioning seat.

[0013] As a further embodiment of the present invention: the length and width of the outer wall of the rectangular card frame are both greater than the length and width of the positioning seat, and the length and width of the inner wall of the rectangular card frame are both less than the length and width of the positioning seat.

[0014] This invention also discloses an integrated CNC and grinding machining method, which uses the aforementioned integrated CNC and grinding machining equipment and includes the following steps: S1: First, use a fixture to mount the workpiece to be processed on top of the positioning seat; S2: The workpiece is processed by controlling the operation of the grinding machine and milling machine through the controller. During this process, the second servo motor and the first servo motor are controlled by the controller. When the second servo motor is running, it will drive the first movable frame to rotate. At this time, the positioning seat will rotate relative to the second movable frame. S3: When the first servo motor operates, it will drive the second movable frame to rotate, causing the second movable frame to tilt relative to the base. This allows the positioning seat to tilt in the front-back and left-right directions, thereby causing the workpiece to tilt. The tilt of the workpiece compensates for the tilt angle of the tool. At this time, the tool does not need to tilt to a large extent to process the workpiece, thus reducing the tool swing angle. S4: When the positioning seat tilts, the piston rod will be squeezed or pulled by the second annular sleeve and the first connecting ball shaft, so that the aqueous solution inside the piston cylinder is discharged through the connecting pipe or the solution inside the water tank is drawn into the piston cylinder through the guide pipe, solenoid valve and guide hole. After the tilt angle of the positioning seat is adjusted, the solenoid valve is closed. The aqueous solution between the bottom of the piston rod and the top of the solenoid valve is de-energized and closed, so that the tilted positioning seat is limited and fixed. S5: After processing is completed, the second servo motor and the first servo motor are controlled by the controller to rotate the positioning seat to a horizontal state, and then the processed workpiece is removed.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting tilt angle limiters, the controller operates the second and first servo motors. When the second servo motor operates, it drives the first movable frame to rotate, causing the positioning seat to rotate relative to the second movable frame. When the first servo motor operates, it drives the second movable frame to rotate, causing the second movable frame to tilt relative to the base. This allows the positioning seat to tilt in the front-back and left-right directions, thus tilting the workpiece. The tilt of the workpiece compensates for the tilt angle of the tool. The tool does not need to tilt significantly to machine the workpiece, thereby reducing the tool swing angle and controlling the radial and axial runout of the tool spindle, resulting in a more precise machining trajectory. It also avoids uneven cutting depth caused by large tool deviation. By adopting a combined angle adjustment mode of "small tool deflection and workpiece fixture tilt," the two angles complement and superimpose, enabling a wider range of machining. With adjustable tilt angles, it can easily process complex structures such as inclined surfaces, grooves, and inclined holes. When the positioning seat tilts, the piston rod is squeezed or pulled by the second annular sleeve and the first connecting ball shaft. This allows the aqueous solution inside the piston cylinder to be discharged through the connecting pipe or the solution inside the water tank to be drawn into the piston cylinder through the guide pipe, solenoid valve, and guide hole. After the tilt angle of the positioning seat is adjusted, the solenoid valve is closed. The de-energization of the solenoid valve eliminates the flow space between the bottom of the piston rod and the top of the solenoid valve, thus limiting and fixing the tilted positioning seat. At the same time, due to the tilt of the positioning seat, the debris on the surface of the workpiece is quickly separated from the workpiece by the cleaning airflow of the equipment, further enhancing the cleaning effect on the top of the positioning seat. After processing, the second servo motor and the first servo motor are controlled by the controller to rotate the positioning seat to a horizontal state, and then the processed workpiece is removed. 2. By setting up a displacement collection component, a rectangular frame is used to block the edge of the positioning seat during workpiece cleaning. This allows debris to fall into the inner side of the collection tank when it separates from the workpiece on the positioning seat. When the positioning seat tilts, the rectangular frame slides towards the lower part of the positioning seat under its own gravity. During this process, the guide rod slides relative to the slider or the slider slides relative to the guide block. When cleaning debris from the workpiece surface, the tilt of the positioning seat causes the debris to be subjected not only to the thrust of the airflow sprayed during equipment cleaning but also to its own gravity. This dual effect improves the debris removal effect, thereby reducing debris on the workpiece surface and preventing debris from affecting subsequent grinding of the workpiece. At the same time, the movement of the rectangular frame changes its position with the tilt of the positioning seat, thus preventing debris from falling to the outside of the collection tank.

A second movable frame 23 is provided at the bottom of the third movable frame 32, which is staggered with the third movable frame 32. A first servo motor 25 is provided on the outside of the second movable frame 23. A base 24 is installed on the top of the partition 9. The second movable frame 23 is rotatably connected to the base 24 via a rotating shaft. A first servo motor 25 is provided on one side of the base 24. The output end of the first servo motor 25 is connected to the second movable frame 23. The tilt limiter also includes four second annular sleeves 19 installed at the bottom of the positioning seat 6. The four second annular sleeves 19 are evenly divided into two groups, and the two groups of second annular sleeves 19 are symmetrically arranged along the transverse central axis of the positioning seat 6. Two second annular sleeves 19 in each group are symmetrically arranged along the transverse central axis of the positioning seat 6. A first connecting ball shaft 20 is provided on the inner side of the second annular sleeve 19. A piston rod 16 is connected to the bottom of the first connecting ball shaft 20. A piston cylinder 12 is sleeved on the outer side of the piston rod 16. A second connecting ball shaft 30 is installed at the bottom of 2. A first annular sleeve 11 is sleeved on the outside of the second connecting ball shaft 30. A connecting pipe 10 penetrating the partition 9 is provided at the bottom of the first annular sleeve 11. A solenoid valve 15 is installed at the bottom of the connecting pipe 10. A guide pipe 13 extending to the inside of the water tank 7 is provided at one end of the solenoid valve 15. The connecting pipe 10 is in communication with the water tank 7 through the solenoid valve 15 and the guide pipe 13. A guide hole 31 penetrating the second connecting ball shaft 30 is opened on the inside of the second connecting ball shaft 30.

[0021] Among them, the angle between the bottom of the third movable frame 32 and the top of the second movable frame 23 is 90 degrees, the center line of the connecting plate 17 is coaxial with the center line of the positioning seat 6, the maximum moving distance of the piston rod 16 relative to the piston cylinder 12 is greater than the distance between the positioning seat 6 and the partition plate 9, the inner wall diameter of the connecting pipe 10 is greater than the outer wall diameter of the piston cylinder 12, and the diameter of the guide hole 31 is greater than the inner wall diameter of the piston cylinder 12.

[0022] In this embodiment: First, the workpiece to be processed is mounted on the positioning seat 6 using a fixture. Then, the grinding machine 4 and milling machine 5 are controlled by the controller 3 to process the workpiece. During this process, the second servo motor 26 and the first servo motor 25 are controlled by the controller 3. When the second servo motor 26 operates, it drives the first movable frame 22 to rotate. At this time, the positioning seat 6 will rotate relative to the second movable frame 23. When the first servo motor 25 operates, it drives the second movable frame 23 to rotate, causing the second movable frame 23 to tilt relative to the base 24. This allows the positioning seat 6 to tilt in the front-back and left-right directions, thereby tilting the workpiece. The tilt of the workpiece compensates for the tilt angle of the tool. At this time, the tool does not need to tilt to a large extent to process the workpiece, thereby reducing the tool swing angle, controlling the radial and axial runout of the tool spindle, and making the machining trajectory more accurate. At the same time, it avoids uneven cutting depth caused by large tool deflection. By adopting a combined angle adjustment mode of "small tool deflection and workpiece fixture tilt", The complementary and superimposed angles of the two components enable a wider range of machining tilt angle requirements, easily completing the machining of complex structures such as inclined surfaces, inclined grooves, and inclined holes. When the positioning seat 6 tilts, the piston rod 16 is squeezed or pulled by the second annular sleeve 19 and the first connecting ball shaft 20, thereby causing the aqueous solution inside the piston cylinder 12 to be discharged through the connecting pipe 10 or the solution inside the water tank 7 to be drawn into the inside of the piston cylinder 12 through the guide pipe 13, the solenoid valve 15, and the guide hole 31. After the tilt angle of the positioning seat 6 is adjusted, the solenoid valve 15 is closed. By de-energizing the solenoid valve 15, the aqueous solution between the bottom of the piston rod 16 and the top of the solenoid valve 15 loses its flow space, thus limiting and fixing the tilted positioning seat 6. At the same time, due to the tilt of the positioning seat 6, the debris on the surface of the workpiece is quickly separated from the workpiece under the action of the cleaning airflow of the equipment, further enhancing the cleaning effect on the top of the workpiece of the positioning seat 6. After the machining is completed, the second servo motor 26 and the first servo motor 25 are controlled by the controller 3 to rotate the positioning seat 6 to a horizontal state, and then the machined workpiece is removed.

[0023] Please refer to this carefully. Figure 1 , Figure 3 , Figure 4 , Figure 5 The material collection component includes guide blocks 18 installed on both sides of the bottom of the positioning seat 6. A slider 21 is movably sleeved on the outer side of the guide block 18. A guide rod 27 extending to the other side of the slider 21 is inserted into one side of the slider 21. A first telescopic spring 28 connected to the slider 21 is provided at one end of the guide rod 27. A second telescopic spring 29 connected to the guide block 18 is provided on one side of the slider 21. The other end of the guide rod 27 is connected to a rectangular frame 14 located on the outer side of the positioning seat 6. A collection groove 33 is opened at the top of the rectangular frame 14.

[0024] Among them, the horizontal height of the top of the rectangular card frame 14 is lower than the horizontal height of the top of the positioning seat 6, the length and width of the outer wall of the rectangular card frame 14 are greater than the length and width of the positioning seat 6, and the length and width of the inner wall of the rectangular card frame 14 are less than the length and width of the positioning seat 6.

[0025] In this embodiment: when cleaning the workpiece, the rectangular frame 14 is used to block the edge of the positioning seat 6, so that the debris falls into the inner side of the collection tank 33 when it separates from the workpiece on the positioning seat 6. When the positioning seat 6 is tilted, the rectangular frame 14 will slide towards the lower part of the positioning seat 6 under its own gravity. During this process, the guide rod 27 slides relative to the slider 21 or the slider 21 slides relative to the guide block 18. When cleaning the debris on the surface of the workpiece, the tilt of the positioning seat 6 makes the debris not only subject to the thrust of the airflow sprayed during the cleaning of the equipment, but also subject to its own gravity. The dual effect improves the debris removal effect, thereby reducing the debris on the surface of the workpiece and preventing the debris from affecting the subsequent grinding of the workpiece. At the same time, the movement of the rectangular frame 14 changes the position of the rectangular frame 14 with the tilt of the positioning seat 6, thereby preventing the debris from falling to the outside of the collection tank 33.

[0026] The following describes a CNC and grinding integrated machining method based on the aforementioned integrated CNC and grinding equipment, specifically including the following steps: S1: First, use a fixture to install the workpiece to be processed on top of the positioning seat 6; S2: The workpiece is processed by controlling the operation of the grinding machine 4 and the milling machine 5 through the controller 3. During this process, the second servo motor 26 and the first servo motor 25 are controlled by the controller 3. When the second servo motor 26 operates, it will drive the first movable frame 22 to rotate. At this time, the positioning seat 6 will rotate relative to the second movable frame 23. S3: When the first servo motor 25 operates, it will drive the second movable frame 23 to rotate, causing the second movable frame 23 to tilt relative to the base 24. This allows the positioning seat 6 to tilt in the front-back and left-right directions, thereby causing the workpiece to tilt. The tilt of the workpiece compensates for the tilt angle of the tool. At this time, the tool does not need to tilt to a large extent to process the workpiece, thereby reducing the tool swing angle. S4: When the positioning seat 6 tilts, the piston rod 16 will be squeezed or pulled by the second annular sleeve 19 and the first connecting ball shaft 20, so that the aqueous solution inside the piston cylinder 12 is discharged through the connecting pipe 10 or the solution inside the water tank 7 is sucked into the inside of the piston cylinder 12 through the guide pipe 13, the solenoid valve 15 and the guide hole 31. After the tilt angle of the positioning seat 6 is adjusted, the solenoid valve 15 is closed. The aqueous solution between the bottom of the piston rod 16 and the top of the solenoid valve 15 is de-energized and closed, so that the tilted positioning seat 6 is limited and fixed. S5: The controller 3 controls the orderly operation of the milling machine 5 and the grinding machine 4 to mill and grind the workpiece. After the workpiece is milled, the cleaning mechanism inside the equipment is activated to clean the workpiece surface. When the debris separates from the workpiece on the positioning seat 6, it falls into the inner side of the collection tank 33. When the positioning seat 6 tilts, the rectangular frame 14 will slide towards the lower part of the positioning seat 6 under its own weight. During this process, the guide rod 27 slides relative to the slider 21 or the slider 21 slides relative to the guide block 18, thus cleaning the debris on the workpiece surface. During cleaning, the tilting of the positioning seat 6 causes the debris to be subjected not only to the thrust of the airflow sprayed during equipment cleaning but also to its own gravity. This dual effect enhances the debris removal effect, thereby reducing debris on the workpiece surface and preventing debris from affecting subsequent grinding of the workpiece. At the same time, the movement of the rectangular frame 14 changes its position with the tilting of the positioning seat 6, thereby preventing debris from falling to the outside of the collection tank 33. After processing, the controller 3 controls the operation of the second servo motor 26 and the first servo motor 25 to rotate the positioning seat 6 to a horizontal state, and then the processed workpiece is removed.

A CNC and grinding integrated machining method, characterized by, The CNC and grinding integrated processing equipment according to any one of claims 1-9 includes the following steps: S1: First, use a fixture to install the workpiece to be processed on top of the positioning seat (6); S2: The workpiece is processed by controlling the operation of the grinding machine (4) and milling machine (5) through the controller (3). During this process, the second servo motor (26) and the first servo motor (25) are controlled by the controller (3). When the second servo motor (26) operates, it will drive the first movable frame (22) to rotate. At this time, the positioning seat (6) will rotate relative to the second movable frame (23). S3: When the first servo motor (25) operates, it will drive the second movable frame (23) to rotate, causing the second movable frame (23) to tilt relative to the base (24). This allows the positioning seat (6) to tilt in the front-back and left-right directions, thereby causing the workpiece to tilt. The tilt of the workpiece compensates for the tilt angle of the tool. At this time, the tool does not need to tilt to a large extent to process the workpiece, thereby reducing the tool swing angle. S4: When the positioning seat (6) tilts, the piston rod (16) will be squeezed or pulled by the second annular sleeve (19) and the first connecting ball shaft (20), so that the aqueous solution inside the piston cylinder (12) is discharged through the connecting pipe (10) or the solution inside the water tank (7) is sucked into the inside of the piston cylinder (12) through the guide pipe (13), the solenoid valve (15) and the guide hole (31). After the tilt angle of the positioning seat (6) is adjusted, the solenoid valve (15) is closed. The aqueous solution between the bottom of the piston rod (16) and the top of the solenoid valve (15) loses its flow space by de-energizing the solenoid valve (15), so that the tilted positioning seat (6) can be limited and fixed. S5: After processing is completed, the second servo motor (26) and the first servo motor (25) are controlled by the controller (3) to make the positioning seat (6) rotate to a horizontal state, and then the processed workpiece is removed.
