Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, specifically to a multi-axis linkage milling and grinding integrated processing device and method. Background Technology

[0002] Turning, milling, and grinding are common machining methods in the production of mechanical parts. When a workpiece has multiple machining surfaces or requires different machining processes, the relative position between the workpiece and the cutting tool needs to be adjusted according to the machining requirements to complete the machining of different parts. When performing turning, milling, and grinding on existing machining equipment, the connection between each machining process is inconvenient. Some workpieces need to be transferred between different machining equipment and re-clamped and positioned, which increases the number of operation steps in the machining process. At the same time, the position of the workpiece will change after re-clamping, affecting the continuity between each machining process.

[0003] During the grinding process, after a certain period of use, the working surface of the grinding wheel will become worn or uneven, requiring the grinding wheel to be dressed before continued use. In the current processing, the connection between grinding wheel dressing and workpiece processing is inconvenient, which will affect the subsequent grinding process. At the same time, a certain amount of machining debris will be generated during turning, milling and grinding. After the debris falls into the equipment, it needs to be cleaned. If it cannot be discharged in time, it will accumulate in the processing area.

[0004] For workpieces with complex curved surfaces, spatial inclined surfaces, irregular contours, or multi-angle features, the spatial attitude adjustment range between the tool and the workpiece is limited when the machining position is adjusted only by the three linear directions of X, Y, and Z. Therefore, it is necessary to introduce a rotatable axis that is synchronously linked with the linear axis to improve the one-time clamping and machining capability of complex products. Thus, a machining device that can perform multi-axis linkage and combine turning, milling, grinding, wheel dressing, and slag removal is needed to meet the requirements of continuous workpiece machining. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-axis linkage turning, milling, and grinding integrated machining device and method, which solves the problems of inconvenient connection of turning, milling, and grinding processes, repeated workpiece clamping, and inconvenience in grinding wheel dressing and slag removal in existing machining equipment.

[0033] Example 1:

[0034] Please see the appendix Figure 1 -Appendix Figure 4 This invention provides a multi-axis linkage milling and turning integrated machining device, including a base 1, which serves as the supporting foundation for the device and is used to install components related to workpiece movement, tool movement, and slag removal.

The X-axis drive motor 16 is used to drive the X-axis moving seat 7 to move along the X-axis direction, so that the worktable 8 and the clamped workpiece can change the processing position with the X-axis moving seat 7. The rotational motion of the worktable 8 is defined as the C-axis. The worktable 8 can rotate and position at any angle or rotate continuously according to CNC machining instructions to adjust the angle position of the workpiece around the C-axis.

[0035] A Y-axis moving seat 11 is slidably connected to the outer wall of the gantry 2. A Z-axis moving seat 12 is slidably connected to the outer wall of the Y-axis moving seat 11.

At the same time, in addition to being able to move linearly along the Z-axis direction, the Z-axis moving seat 12 also has a B-axis rotational degree of freedom, which can rotate at any angle according to the machining needs, so that the tool magazine 13 and the tool can obtain the required tilting posture relative to the workpiece.

[0036] Please see the appendix Figure 1 -Appendix Figure 3The outer wall of the base 1 is fixedly connected with a first high guide rail 3 and a first low guide rail 4. The first high guide rail 3 and the first low guide rail 4 are arranged along the moving direction of the X-axis moving seat 7. The X-axis moving seat 7 is straddling the first high guide rail 3 and the first low guide rail 4 and is slidably connected to the first high guide rail 3 and the first low guide rail 4 respectively. The X-axis drive motor 16 is connected to the X-axis moving seat 7. When the X-axis drive motor 16 is working, it can drive the X-axis moving seat 7 to reciprocate along the first high guide rail 3 and the first low guide rail 4, thereby driving the worktable 8 and the workpiece clamped on the worktable 8 to move along the X-axis direction.

[0037] Please see the appendix Figure 1 - Appendix Figure 3 The worktable 8 is rotatably connected to the X-axis moving seat 7, and the rotation axis of the worktable 8 is set along the Z-axis direction. When performing turning, the workpiece is fixed on the worktable 8, and the workpiece is rotated by the worktable 8. The positions of the X-axis moving seat 7, Y-axis moving seat 11 and Z-axis moving seat 12 are adjusted to make the turning tool correspond to the workpiece to be processed, so as to complete the turning of the corresponding part of the workpiece. When performing milling or grinding, the relative position between the tool and the workpiece is changed by the linkage between the moving seats, so that the tool completes the processing according to the corresponding processing trajectory.

[0038] Please see the appendix Figure 1 and attached Figure 4 The outer wall of the gantry 2 is fixedly connected with a second high guide rail 5 and a second low guide rail 6. The Y-axis moving seat 11 is slidably connected to the second high guide rail 5 and the second low guide rail 6 respectively. The Y-axis drive motor 17 is located on one side of the gantry 2 and is connected to the Y-axis moving seat 11 for transmission. When the Y-axis drive motor 17 is working, it can drive the Y-axis moving seat 11 to move back and forth along the second high guide rail 5 and the second low guide rail 6, thereby changing the position of the Z-axis moving seat 12 and the tool magazine 13 in the Y-axis direction.

[0039] Please see the appendix Figure 1 and attached Figure 4 The Z-axis moving seat 12 is slidably mounted on the outer wall of the Y-axis moving seat 11.

The tool magazine 13 is located on the side of the Z-axis moving seat 12 close to the worktable 8, so that the Z-axis moving seat 12 can drive the tool magazine 13 to move synchronously when it moves up and down. Through the cooperation of the Y-axis drive motor 17 and the Z-axis drive motor 18, the positions of the tool magazine 13 and the corresponding tools in the Y-axis and Z-axis directions can be adjusted, and in conjunction with the movement of the X-axis moving seat 7 along the X-axis direction, the tools can be aligned with the workpiece to be processed.

[0040] Please see the appendix Figure 1 - Appendix Figure 3A mounting base 9 is fixedly connected to the outer wall of the base 1. A first motor 10 is fixedly connected to the mounting base 9. A diamond turntable 20 is fixedly connected to the output end of the first motor 10. The diamond turntable 20 is located on the outer side of the first high-position guide rail 3. The diamond turntable 20 is used to dress the grinding wheel used in grinding. When the grinding wheel needs to be dressed after grinding, the movement of the Y-axis moving seat 11 and the Z-axis moving seat 12 drives the tool magazine 13 and the grinding wheel to be dressed to move, so that the grinding wheel reaches the dressing position corresponding to the diamond turntable 20. After the first motor 10 is started, it drives the diamond turntable 20 to rotate, so that the working surface of the grinding wheel contacts the diamond turntable 20. The diamond turntable 20 dresses the working surface of the grinding wheel, so that the working surface of the grinding wheel is restored to flatness. After dressing, the tool magazine 13 drives the grinding wheel away from the diamond turntable 20 and moves the grinding wheel back to the corresponding grinding position.

[0041] Please see the appendix Figure 1 - Appendix Figure 3 The outer wall of the base 1 is provided with a slag discharge groove 15, and a spiral slag discharge shaft 14 is provided in the slag discharge groove 15. The spiral slag discharge shaft 14 is arranged along the length direction of the slag discharge groove 15. A second motor 19 is fixedly connected to the outer wall of the base 1, and the output end of the second motor 19 is connected to the spiral slag discharge shaft 14 for transmission. During the turning, milling and grinding processes, the machining debris generated enters the slag discharge groove 15. After the second motor 19 is started, the second motor 19 drives the spiral slag discharge shaft 14 to rotate. The spiral slag discharge shaft 14 pushes the machining debris in the slag discharge groove 15 to move along the slag discharge groove 15 and discharge it, thereby centrally discharging the debris generated during the processing.

[0042] In a preferred embodiment of the present invention, the moving directions of the X-axis moving seat 7, the Y-axis moving seat 11, and the Z-axis moving seat 12 are perpendicular to each other. The X-axis moving seat 7 drives the worktable 8 and the workpiece to move along the X-axis direction; the Y-axis moving seat 11 drives the Z-axis moving seat 12 and the tool magazine 13 to move along the Y-axis direction; and the Z-axis moving seat 12 drives the tool magazine 13 to move along the Z-axis direction. The X-axis drive motor 16, the Y-axis drive motor 17, and the Z-axis drive motor 18 control the movement of their respective moving seats, enabling multi-axis linkage between the workpiece and the tool, and combining this with… The rotating worktable 8 adjusts the relative position between the workpiece and the tool according to different machining processes to perform turning, milling and grinding. When machining complex products, the five axes X, Y, Z, B and C can be synchronously interpolated according to the CNC program. The X, Y and Z axes are used to complete spatial position movement, the B axis is used to adjust the tool posture, and the C axis is used to adjust the workpiece rotation angle, so that the tool and the workpiece maintain a continuous spatial linkage relationship during the machining process, thereby completing the turning, milling or grinding of complex curved surfaces, spatial inclined surfaces, irregular contours and multi-angle holes and grooves.

[0043] Example 2:

[0044] Please see the appendix Figure 5 The present invention also provides a multi-axis linkage turning, milling and grinding integrated machining method, comprising the following steps:

[0045] S1. Clamp the workpiece to be processed on the worktable 8. According to the workpiece's processing position, start the X-axis drive motor 16, Y-axis drive motor 17, and Z-axis drive motor 18. The X-axis drive motor 16 drives the X-axis moving seat 7 to move along the X-axis direction, the Y-axis drive motor 17 drives the Y-axis moving seat 11 to move along the Y-axis direction, and the Z-axis drive motor 18 drives the Z-axis moving seat 12 to move along the Z-axis direction, so that the workpiece corresponds to the processing position of the corresponding tool. During positioning and subsequent processing, the B-axis rotation of the Z-axis moving seat 12 and the C-axis rotation of the worktable 8 can also be controlled synchronously, so that the five axes of X, Y, Z, B, and C are linked according to the preset trajectory.

[0046] S2. When performing turning, select a turning tool from the tool magazine 13 and move the turning tool to the machining position. Drive the workpiece to be machined to rotate through the worktable 8. Control the X-axis moving seat 7, Y-axis moving seat 11 and Z-axis moving seat 12 in linkage according to the turning trajectory of the workpiece to change the relative position between the turning tool and the workpiece, so that the turning tool can perform turning machining on the corresponding part of the workpiece.

[0047] S3. When performing milling, select a milling tool from the tool magazine 13 and move the milling tool to the machining position. Rotate the milling tool and control the X-axis drive motor 16, Y-axis drive motor 17 and Z-axis drive motor 18 to move according to the milling trajectory of the workpiece. This causes the X-axis moving seat 7, Y-axis moving seat 11 and Z-axis moving seat 12 to move together and adjust the relative position between the milling tool and the workpiece so that the milling tool can perform milling on the workpiece along the corresponding machining trajectory.

[0048] S4. After grinding, when the grinding wheel needs dressing, the tool magazine 13 is moved by the Y-axis moving seat 11 and the Z-axis moving seat 12, so that the grinding wheel to be dressed on the tool magazine 13 is moved to the dressing position corresponding to the diamond turntable 20. The first motor 10 is started, and the first motor 10 drives the diamond turntable 20 to rotate, so that the working surface of the grinding wheel contacts the diamond turntable 20, and the working surface of the grinding wheel is dressed by the diamond turntable 20, so that the working surface of the grinding wheel is restored to flatness. After the grinding wheel dressing is completed, the grinding wheel is moved away from the diamond turntable 20 by the tool magazine 13 and moved to the corresponding processing position for continued grinding.

[0049] S5. During the turning, milling and grinding processes, the machining chips generated enter the slag discharge groove 15. The second motor 19 is started, which drives the spiral slag discharge shaft 14 to rotate, so that the spiral slag discharge shaft 14 pushes the machining chips along the slag discharge groove 15 and discharges them. After the workpiece completes the corresponding turning, milling and grinding processes, the X-axis moving seat 7, Y-axis moving seat 11 and Z-axis moving seat 12 are reset, and the processed workpiece is removed from the worktable 8.

This will cause the X-axis moving seat (7), Y-axis moving seat (11) and Z-axis moving seat (12) to work together to adjust the relative position between the milling tool and the workpiece, thus completing the milling process. S4. After grinding, when the grinding wheel needs to be dressed, control the tool magazine (13) to move automatically, so that the grinding wheel to be dressed moves to the dressing position corresponding to the diamond turntable (20), start the first motor (10) to drive the diamond turntable (20) to rotate, and make the grinding wheel contact the diamond turntable (20). The working surface of the grinding wheel is dressed by the diamond turntable (20) to restore the working surface of the grinding wheel to flatness. After dressing is completed, control the tool magazine (13) to drive the grinding wheel away from the diamond turntable (20) and move it to the processing position. S5. During the processing, the debris falls into the slag discharge trough (15). The second motor (19) is started to drive the spiral slag discharge shaft (14) to rotate, so that the processing debris is discharged along the slag discharge trough (15). After turning, milling and grinding are completed, the X-axis moving seat (7), Y-axis moving seat (11) and Z-axis moving seat (12) are reset, and the processed workpiece is removed from the worktable (8).
