Description

Technical Field

[0001] This invention relates to the field of machine tool technology, specifically to a combined cutting device and method for single-column vertical milling and turning composite machining. Background Technology

[0002] The single-column vertical turning and milling machine is an advanced machining equipment that integrates turning and milling functions. Supported by a single column, it features a compact structure with good rigidity, enabling efficient machining within a limited space, and is particularly suitable for machining medium to large workpieces. Currently, single-column vertical milling and turning machines are widely used. These machines generally only support a single-tool machining mode or a fixed dual-tool machining mode. When it is necessary to switch from turning processes to different milling or drilling processes, the tool changing operation is extremely complicated. It not only requires operators to have high professional skills and rich experience, but the entire changeover process is also time-consuming, which greatly reduces production efficiency and increases time costs. After machining is completed, a large amount of metal chips will accumulate on the surface of the clamping plate. If these chips are not cleaned in time, the sharp chips can easily scratch the surface of the workpiece, affecting the appearance quality and precision of the workpiece, leading to an increase in the product defect rate.

[0003] Therefore, the present invention proposes a combined cutting device and method for single-column vertical turning and milling composite machining to solve the above problems. Summary of the Invention

[0015] This invention provides a combined cutting device and method for single-column vertical turning and milling machining. Compared with the prior art, it has the following advantages: 1. A combined cutting device and method for single-column vertical turning and milling composite machining, which, through the design of a bolt-removable support plate in the combined cutting mechanism, combined with the rotational positioning function of the first and second cutting machining components, enables rapid and arbitrary combination of milling cutters or drill bits. For example, by driving the first gear to rotate the first gear ring with the second motor, the required first milling component is rotated to the bottom; by driving the second gear to rotate the second gear ring with the electric motor, the required second milling component is rotated to the bottom, satisfying the composite machining needs of turning, milling, drilling, etc. In this design, the multi-tool combination capability of the combined cutting mechanism reduces tool change time and significantly improves workpiece machining efficiency. Furthermore, by adjusting the combination method and spacing of the first and second cutting machining components, it can adapt to metal parts of different sizes and with different machining requirements, achieving "one machine for multiple uses" and reducing enterprise equipment investment costs.

[0016] 2. A combined cutting device and method for single-column vertical milling and turning composite machining, wherein the spacing adjustment component is driven by a fourth motor to rotate the transmission shaft, synchronously driving the first and second bevel gear disks to rotate, and can simultaneously adjust the lifting positions of multiple first and second milling components to achieve precise adjustment of the tool spacing. When only the height of the second milling component needs to be adjusted, the electric push rod pulls the first push-pull rod to separate the second bevel gear disk from the multiple second bevel gears, driving only the first bevel gear disk to rotate, achieving independent adjustment.

[0017] 3. A combined cutting device and method for single-column vertical milling and turning composite machining, through the linkage design of the support frame and the workpiece clamping mechanism, the workpiece clamping mechanism drives the brush to rotate and clean the clamping plate through the inclined surface cooperation of the wedge block and the guide ball. When the support frame moves, the brush rotates and cleans the clamping plate. When the wedge block is pushed in, the rack and gear mesh to drive the brush to rotate. At the same time, the bristles at the bottom of the brush contact the top of the clamping plate, pushing the metal chips into the wedge groove. The wedge design of the wedge groove, due to its low position away from the circular groove, allows the chips to slide quickly to the waste collection plate. The bottom of the movable groove of the clamping block is connected to the waste collection plate to ensure complete chip collection. The self-cleaning function of the workpiece clamping mechanism reduces downtime for cleaning. After milling is completed, the support frame continues to move to drive the workpiece clamping mechanism to automatically clean the chips without manual intervention, thus improving the overall processing efficiency.

[0018] 4. A combined cutting device and method for single-column vertical milling and turning composite machining, wherein the first milling component achieves rapid docking between the power connection sleeve and the power transmission head through the magnetic attraction of the electromagnet ring and the ferromagnetic ring, and the design of the delayed touch switch ensures stable and reliable power connection and avoids misoperation.

[0030] This invention also provides a combined cutting method for single-column vertical milling and turning machining, the method comprising the following steps: Step 1: Clamp the workpiece to be milled on the top of the workpiece clamping mechanism 9, and adjust the combined cutting mechanism 8 according to the workpiece milling requirements to meet the workpiece composite milling requirements. Step 2: The height of the combined cutting mechanism 8 gradually decreases and gradually approaches the workpiece clamping mechanism 9. The workpiece is milled using the milling cutter on the combined cutting mechanism 8. Step 3: After milling is completed, the support frame 3 continues to move closer to the workpiece clamping mechanism 9 at the milling position to drive the workpiece clamping mechanism 9 to self-clean the metal chips on its surface.

[0031] The metal workpiece to be milled is placed on top of the clamping plate 93 and clamped. Then, according to the workpiece processing requirements, multiple first milling components 87 and second milling components 813 in the first and second cutting processing components are combined. During the combination, the controller first starts the second motor 84 to drive the first gear 85 to rotate 90 degrees each time. The first gear ring 83 rotates under the drive of the first gear 85 until the required first milling component 87 rotates to the bottom.

[0032] Next, the electric motor 811 is started to drive the second gear 810 to rotate the second gear ring 89 by 90 degrees each time until the circular support plate 88 rotates and drives the required second milling component 813 to rotate to the bottom. If only one of the first milling components 87 or one of the second milling components 813 is needed to participate in the cutting work, the controller can rotate only the required first milling component 87 or second milling component 813 to the bottom, while rotating the other first milling components 87 or second milling components 813 to other positions away from the bottom position to avoid interfering with the cutting work.

[0033] Next, the transmission shaft 819 is driven to rotate by the fifth motor 818, which can simultaneously drive the second bevel gear disk 824 and the first bevel gear disk 821 to rotate, thereby simultaneously driving multiple first bevel gears 8133 and second bevel gears 817 to rotate. This causes the first milling assembly 87 located in the first lifting groove 86 or the second milling assembly 813 located in the second lifting groove 812 to move up or down in its position, thereby synchronously increasing or decreasing the distance between the ends of the second cutter head 8135 and the first cutter head 875 to meet the milling work of workpieces of different sizes. When only the position adjustment of the second milling assembly 813 is required, the first push-pull rod 825 is pulled by activating the electric push rod 826, thereby causing the second bevel gear 824 and multiple second bevel gear 824 to separate. The fifth motor 818 can be activated again to drive only the first bevel gear 821 to rotate, thereby driving the first bevel gear 8133 at multiple positions to rotate, and thus only the height of the second milling assembly 813 is adjusted. When the required first milling component 87 rotates to its lowest position, the delayed touch switch 8154 is triggered by the touch block 8155 at the corresponding position. The circuits containing the fourth motor 8151 and the electromagnet ring 8153 are connected and power is supplied with a delay. The delayed power supply time of the circuit containing the electromagnet ring 8153 is less than that of the circuit containing the fourth motor 8151. When the electromagnet ring 8153 is powered, it generates magnetic force, and the ferromagnetic ring 878 is attracted to the electromagnet ring 8153 to achieve mutual adhesion. The power connection sleeve 877 is magnetically connected. The force pulls towards the power transmission head 8152, causing the power connection sleeve 877 to be fitted onto the outer wall of the power transmission head 8152, thus completing the power connection between the power connection sleeve 877 and the power transmission head 8152. The spring 876 is compressed and produces elastic deformation. When the circuit where the electromagnet ring 8153 is located is disconnected, it loses its magnetic force. The power connection sleeve 877 is disengaged from the power transmission head 8152 under the elastic force of the spring 876. The second milling assembly 813 is only powered by the controller when it rotates to the lowest working position.

[0034] Next, after the cutting operation is completed, the first milling assembly 87 and the second milling assembly 813 are rotated to a position away from the workpiece clamping mechanism 9. At this time, the controller controls the first motor 5 to drive the transverse lead screw 4 to rotate a fixed number of turns. The side wall of the support frame 3 is gradually pushed into the cylinder 91 by the second push-pull rod 917 in close contact. The guide ball 915 is lifted along the slope of the wedge block 916, while the fourth gear 911 slides along the outer wall of the lifting rod 910 to maintain its original height, until the brush 99 is lifted to a height slightly higher than the height of the clamping block in the clamping plate 93, with only the bristles at the bottom of the brush 99 contacting the top of the clamping plate 93. At this time, the guide ball 915 is pushed from the top of the wedge block 916. As the slope slides to its horizontal plane, the brush 99 maintains its height. When the wedge block 916 continues to move into the cylinder 91, the rack 914 and the fourth gear 911 mesh, driving the fourth gear 911 to rotate during the movement. The rotating brush 99 pushes away the metal shavings located on top of the clamping plate 93. Because the wedge groove 97 is wedge-shaped and positioned lower than the circular groove 96, a significant height difference is formed at both ends of the wedge groove 97. Metal shavings falling into the wedge groove 97 can quickly slide into the waste collection plate 92. The bottom of the movable groove of the clamping block is connected to the waste collection plate 92, allowing metal shavings falling into it to directly enter the waste collection plate 92. When one end of the wedge block 916 loses external force, the return spring pulls it back to its original position. The circular mounting base 98 rotates in the opposite direction the same number of times and automatically enters the corresponding wedge groove 97.
