Description

Technical Field

[0001] The present invention relates to the technical field of combined turning and milling processing tools, and particularly to a compact, efficient and precision vertical combined turning and milling machining center. Background Art

[0002] Turning and milling are two important machining methods in mechanical processing. The history of turning can be traced back to ancient times. At that time, people used simple tools, such as manual tools, to perform rotary cutting on materials such as wood and stone to manufacture simple circular objects. The introduction of mechanical power enabled the development of lathes, which could process metal materials, improving processing efficiency and accuracy. In the 20th century, with the development of numerical control technology, lathes gradually transformed from traditional manual control to numerical control. The numerical control system can accurately control the movement trajectory of the tool and cutting parameters, achieving higher machining accuracy and automation, making it possible to machine parts with complex shapes. At the same time, the continuous improvement of tool materials, such as the emergence of carbide, ceramic and other tools, has improved the cutting performance and service life of the tools, further promoting the development of turning technology. Early milling was mainly carried out on simple milling machine equipment. The rotary movement of the tool and the feeding movement of the workpiece were realized through manual or mechanical transmission, with low processing efficiency and limited processing accuracy, mainly used for some simple plane, groove and other processing. After the mid-20th century, numerical control technology was applied to milling machines, enabling milling to enter a new stage. The numerical control milling machine can accurately control the movement of the tool through programming to achieve the machining of complex shapes. At the same time, the development of automation technology, such as the application of automatic tool changing devices, automatic workpiece loading and unloading systems, etc., has improved the automation level and production efficiency of milling. In addition, the emergence of CAD / CAM technology has made the design and programming of parts more convenient and accurate, further promoting the development of milling technology.

[0003] The main processing contents of disc-shaped rotating parts include turning of outer circles, inner holes, and end faces, drilling, milling, and tapping of outer circles and end faces. The traditional process uses 1 numerical control lathe to complete the turning content, and adds 1 vertical machining center to complete drilling, milling, and tapping. Two machines, two setups, at least two processes. The establishment of two devices increases the floor area of the device, and repositioning is required for the workpiece during re-clamping, which will affect the processing efficiency of the workpiece. Moreover, during the processing of the workpiece, a large amount of debris will be generated. The existing device cannot discharge these debris in real time following the processing. The debris remaining in the device affects processing on the one hand, and on the other hand, the debris may float into the interior of the device, causing the device to jam. And the existing device often installs two positioning clamps to adapt to different processes of turning and milling. If turning and milling are combined into one, a positioning clamp applicable to both processing processes needs to be designed. Therefore, the above problems need to be solved.

[0042] Working principle: In this embodiment, the present invention also proposes a method for using a compact, efficient, and precision vertical turning and milling compound machining center, including the following steps:

[0043] Step 1: First, connect the first air port 15, the second air port 50, and the other air vents to the air supply plate 2 through an air pipe. Then, power on the device, take out the workpiece, place it on the positioning clamp 34, and position the workpiece through the internal clamping block.

[0044] Step 2: According to the position of the positioning clamp 34, the first linear motor 8 and the second linear motor 9 are started, driving the turning table 11 to move to the upper end of the positioning clamp 34 and then descending. At this time, the servo tool post 13 abuts against the workpiece. Then, the third DC motor 35 is started, driving the positioning clamp 34 to rotate at high speed. Since the turning tool abuts against the workpiece, during the rotation process, the turning tool performs turning processing on the workpiece. Then, the first DC motor 12 is started, driving the servo tool post 13 to rotate, and replacing the suitable turning tool according to the processing requirements. The workpiece is turned by turning tools of different specifications. During the turning process, the workpiece also needs to change its own height to adapt to the turning tool. And during the turning process, the device is prevented from overheating by injecting coolant into the turning table 11, and the bottom end of the servo tool post 13 blows air to cool the workpiece.

[0045] Step 3: When the height of the workpiece needs to be changed, the first caliper 41 clamps the external gear ring 39 inward. At this time, the external gear ring 39 no longer rotates, but the rotating shaft of the positioning mechanism is still rotating. Under the cooperation of the external gear ring 39 and the thread, the external gear ring 39 moves upward and drives the positioning clamp 34 to rise through the second expansion airbag 40. After reaching the appropriate position, the first caliper 41 is released.

[0046] Step 4: After the turning processing is completed, the first linear motor 8 cooperates with the second linear motor 9 to drive the turning table 11 to move to the upper end of the positioning clamp 34. Then, the second DC motor 21 is started to drive the milling cutter 20 to rotate through the rotating shaft, thereby milling the workpiece. During the milling process, the positioning clamp 34 cannot rotate. Therefore, under the cooperation of the air supply plate 2 and the second caliper 43, the clamping block 42 clamps the chuck, and at the same time, the first caliper 41 clamps the external gear ring 39. At this time, the positioning clamp 34 is in an immovable state. Then, under the cooperation of the cylinder 22, the auxiliary shaft 24, and the auxiliary rod 25, the milling cutter 20 is driven to move up and down. Driven by the third DC motor 35, the milling cutter 20 rotates to process the workpiece. At the same time, the second DC motor 21 drives the turntable 27 and the turret 28 to rotate. When the milling cutter 20 of the appropriate specification rotates to the notch at the bottom end of the turntable 27, the second tool groove 30 rotates. At the same time, the rotating clamping ring 29 removes the second tool groove 30 through the corresponding card slot and rotates it to the vicinity of the milling mechanism. At this time, the milling device moves to the upper end of the second tool groove 30, and then the second tool groove 30 is installed at the bottom end of the milling mechanism under the cooperation of the cylinder 22 and the limit block 26.

[0047] Step 5, a large amount of debris will be generated during the processing. These debris slide down to the conveyor belt 45 via the guide plate. At this time, the fourth DC motor 47 starts to drive the conveyor belt 45 to move backward. At this time, the first air outlet 48 emits an upward airflow to blow the debris upward. At the same time, the second air outlet 49 at the bottom of the trolley 44 forms a suction force from top to bottom, cooperating with the limit shell 46 to form an air duct. When the debris moves to the top of the conveyor belt 45, it is sucked into the trolley 44 for collection. After the processing is completed, first reset the device, and then cut off the power supply of the device.
