Description

Technical Field

[0001] This invention relates to the field of turning-milling composite machining tools, and more particularly to a compact, high-efficiency, precision vertical turning-milling composite machining center. Background Technology

[0002] Turning and milling are two important machining methods. The history of turning can be traced back to ancient times, when people used simple tools, such as hand cutters, to rotary cut materials like wood and stone to create simple round objects. The introduction of mechanical power led to the development of lathes, enabling them to machine metal materials and improving machining efficiency and precision. In the 20th century, with the development of CNC technology, lathes gradually shifted from traditional manual control to CNC machining. CNC systems can precisely control the movement trajectory and cutting parameters of the cutting tool, achieving higher machining accuracy and automation, making it possible to machine complex-shaped parts. Simultaneously, continuous improvements in tool materials, such as the emergence of cemented carbide and ceramic tools, have improved the cutting performance and lifespan of tools, further promoting… The development of turning technology has been a driving force. Early milling was mainly carried out on simple milling machines, where the rotation of the cutting tool and the feed of the workpiece were achieved manually or mechanically. This resulted in low processing efficiency and limited accuracy, and was primarily used for simple machining of planes and grooves. From the mid-20th century onwards, the application of CNC technology to milling machines ushered in a new era for milling. CNC milling machines can precisely control the movement of the cutting tool through programming, enabling the machining of complex shapes. Simultaneously, the development of automation technology, such as automatic tool changers and automatic workpiece loading and unloading systems, has improved the automation level and production efficiency of milling. Furthermore, the emergence of CAD / CAM technology has made part design and programming more convenient and precise, further propelling the development of milling technology.

[0003] The main machining operations for disc-shaped rotating parts include turning of the outer diameter, inner diameter, and end face; drilling, milling, and tapping of the outer diameter and end face. Traditional processes use one CNC lathe for turning and one vertical machining center for drilling, milling, and tapping. This requires two machine tools, two clamping operations, and at least two processes. The two setups increase the footprint, and the need for repositioning the workpiece after clamping affects machining efficiency. Furthermore, the machining process generates a large amount of debris, which the existing setup cannot remove in real time. Debris remaining inside the setup not only affects machining but may also cause jamming. Additionally, existing setups often have two locating clamps to accommodate different turning and milling operations. If turning and milling are combined into one, a locating clamp suitable for both operations needs to be designed. Therefore, these problems need to be addressed. Summary of the Invention

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

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

[0044] Step 2: Based on 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 descend. At this time, the servo tool holder 13 comes into contact with the workpiece. At this time, the third DC motor 35 is started, driving the positioning clamp 34 to rotate at high speed. Since the turning tool comes into contact with the workpiece, the turning tool performs turning on the workpiece during the rotation. Then the first DC motor 12 is started, driving the servo tool holder 13 to rotate. According to the processing requirements, a suitable turning tool is changed. The workpiece is turned by turning tools of different specifications. During the turning process, the workpiece also needs to change its height to adapt to the turning tool. During the turning process, coolant is injected into the turning table 11 to prevent the device from overheating, and the bottom of the servo tool holder 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 outer toothed ring 39 inward. At this time, the outer toothed ring 39 no longer rotates, but the shaft of the positioning mechanism continues to rotate. With the cooperation of the outer toothed ring 39 and the thread, the outer toothed ring 39 moves upward and drives the positioning clamp 34 to rise through the second telescopic airbag 40. After reaching the appropriate position, the first caliper 41 releases.

[0046] Step four: After the turning process is completed, the first linear motor 8, in conjunction with the second linear motor 9, moves the turning table 11 to the upper end of the positioning clamp 34. Then, the second DC motor 21 starts, driving the milling cutter 20 to rotate via the rotating shaft, thereby milling the workpiece. During milling, the positioning clamp 34 cannot rotate. Therefore, with the cooperation of the air supply plate 2 and the second caliper 43, the clamping block 42 clamps the chuck, while the first caliper 41 clamps the external gear ring 39. At this time, the positioning clamp 34 is immobile. Subsequently, the cylinder 22, in conjunction with the auxiliary shaft 24 and the auxiliary rod 25, drives... The milling cutter 20 is raised and lowered. 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 rotating frame 28 to rotate. When the milling cutter 20 of the appropriate size rotates to the bottom notch of the turntable 27, the second cutter groove 30 rotates. At the same time, the rotating retaining ring 29 removes the second cutter groove 30 through the corresponding retaining groove and rotates it to the vicinity of the milling mechanism. At this time, the milling device moves to the upper end of the second cutter groove 30. Then, with the cooperation of the cylinder 22 and the limit block 26, the second cutter groove 30 is installed at the bottom end of the milling mechanism.

[0047] Step 5: During the processing, a large amount of debris will be generated. This debris will slide down onto the conveyor belt 45 via the guide plate. At this time, the fourth DC motor 47 will start and drive the conveyor belt 45 to move towards the rear end. At this time, the first air vent 48 will emit an upward airflow, blowing the debris upward. At the same time, the second air vent 49 at the bottom of the trolley 44 will form a suction force from top to bottom, which, together with the limiting shell 46, will form an air duct. When the debris moves to the top of the conveyor belt 45, it will be sucked into the trolley 44 for collection. After the processing is completed, the device will be reset first, and then the device will be powered off.
