Description

Technical Field

[0001] This utility model relates to the field of precision machining equipment technology, specifically a quick-change additive head mechanism and a five-axis linkage additive and subtractive composite machining equipment. Background Technology

[0002] In the field of precision machining, traditional manufacturing processes typically separate additive manufacturing (such as arc welding and laser cladding) from subtractive machining (such as milling and grinding). Existing technologies have the following drawbacks:

[0003] 1. Additive manufacturing equipment can only complete the blank forming. Complex curved parts need to be clamped twice to a five-axis machine tool for precision machining, which leads to the accumulation of positioning errors and the process switching takes up to several hours.

[0004] 2. Conventional five-axis machine tools lack integrated additive manufacturing modules, making it impossible to achieve additive-subtractive collaborative machining in the same coordinate system, which makes it difficult to meet the integrated manufacturing needs of complex structural parts. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-change additive manufacturing head mechanism, comprising a main support, a welding torch, a quick-change tool holder, a molten pool monitoring component, and a dust removal component. The welding torch is connected to the main support, the quick-change tool holder is integrated on the main support and its central axis coincides with the welding torch axis, the molten pool monitoring component is arranged on the main support to monitor the molten pool status in real time, and the dust removal component is arranged around the welding torch to suck up the smoke generated by the welding torch.

[0011] A five-axis linkage additive and subtractive manufacturing composite processing equipment includes a quick-change additive head mechanism, a five-axis machining center, a rotary mechanism, and an additive process control cabinet. The five-axis machining center is equipped with a CNC system and a controllable spindle, and the spindle is detachably connected to the quick-change additive head mechanism via a quick-change tool holder. The rotary mechanism is located on the inner wall of the five-axis machining center and is used to drive the additive head mechanism to rotate and switch between a machining position and a clearance position. The additive process control cabinet is communicatively connected to the five-axis machining center and integrates a welding power supply, a wire feeding control module, and a data interaction interface to drive the quick-change additive head mechanism to perform additive manufacturing.

[0012] Preferably, the rotating mechanism includes a fixed seat fixed to the inner wall of a five-axis machining center, a bearing mounted on the fixed seat, a rotating shaft rotatably connected to the bearing, a mounting part mounted on the side of the rotating shaft and detachably mounting the quick-change additive head mechanism, and a rotating cylinder mounted on the fixed seat to drive the rotating shaft to rotate.

[0015] Preferably, the balancing suspension assembly includes a square tube support vertically mounted on the five-axis machining center and a balancing hanger mounted on the square tube support.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by integrating the quick-change additive head mechanism into the five-axis machining tool through the rotary mechanism, the in-situ switching between additive manufacturing and subtractive manufacturing can be realized, which can meet the integrated high-precision machining of complex structural parts.

[0024] Please see Figures 1-2 The figure shows a quick-change additive manufacturing head mechanism 1, including a main support 11, a welding torch 12, a quick-change tool holder 13, a molten pool monitoring component 14, and a dust removal assembly 15. The welding torch 12 is connected to the main support 11, and the quick-change tool holder 13 is integrated on the main support 11 with its central axis coinciding with the axis of the welding torch 12. The quick-change tool holder 13 includes a standardized mechanical interface for connection to a machine tool spindle, as well as an electrical connector and a quick-connect pneumatic connector integrated within the interface. In this embodiment, the quick-change tool holder 13 uses an SHK63A model tool holder. The quick-change tool holder 13 can also be replaced with other machine tool spindle tool holder models to ensure compatibility with different machine tools. The molten pool monitoring component 14 is arranged on the main support 11 to monitor the molten pool status in real time. In this embodiment, the molten pool monitoring component 14 is an industrial camera at a 10-60° angle to the welding torch 12. The optical axis and the working end of the welding torch 12 form an observation optical path intersecting the molten pool area to monitor the molten pool status in real time. More specifically, the angle between the industrial camera and the welding torch unit is 45°, and the industrial camera lens is equipped with an anti-spatter protective cover to prevent liquid in the molten pool from splashing onto the industrial camera lens and causing damage or affecting vision. The dust removal component 15 is arranged around the welding torch 12 and is used to suck up the fumes generated by the welding torch 12. In this embodiment, the main support 11 is hollowed out to form a fume channel. The dust removal component 15 includes a smoke inlet 15a connected to the head end of the fume channel and a dust removal hose 15a connected to the tail end of the fume channel. The end of the dust removal hose 15b is connected to the dust collection box. The fumes generated by the welding torch 12 are sucked in through the smoke inlet 15a, pass through the fume channel inside the main support 11, and are then discharged into the dust collection box for collection by the dust removal hose 15a.

[0025] Example 2

[0026] Please see Figures 1-4The diagram illustrates a five-axis linkage additive and subtractive manufacturing composite processing equipment, comprising a quick-change additive head mechanism 1, a five-axis machining center 2, a rotary mechanism 3, and an additive process control cabinet 4. The five-axis machining center 2 is equipped with a CNC system and a controllable spindle 21, which is detachably connected to the quick-change additive head mechanism 1 via a quick-change tool holder 13. The rotary mechanism 3 is located on the inner wall of the five-axis machining center 2 and is used to drive the additive head mechanism to rotate and switch between the machining position and the clearance position. The additive process control cabinet 4 is communicatively connected to the five-axis machining center 2 and integrates a welding power supply, wire feeding control module, and data interaction interface. It is used to drive the quick-change additive head mechanism 1 to perform additive manufacturing. When the equipment requires additive processing, the rotary mechanism 3... The quick-change additive head mechanism 1 is rotated 90° to the left, and the spindle 21 of the five-axis machining center 2 moves above the quick-change additive head mechanism 1 and descends until the quick-change tool holder 13 connects with the spindle 21. At this time, the rotary mechanism 3 returns to its original position. The five-axis machining center 2 drives the quick-change additive head mechanism 1 to perform additive processing through the spindle 21. After the additive processing is completed, the rotary mechanism 3 rotates 90° to the left again. The spindle 21 of the five-axis machining center 2 drives the quick-change additive head mechanism 1 to the position of the rotary mechanism 3, and puts the quick-change additive head mechanism 1 back on the rotary mechanism 3. The rotary mechanism 3 drives the quick-change additive head mechanism 1 to return to its original position. The spindle 21 of the five-axis machining center 2 then retrieves a tool from the tool magazine of the machine tool for subtraction processing.

[0027] Example 3

[0028] Please see Figures 1-5 This embodiment further explains Example 2. The rotating mechanism 3 shown in the figure includes a fixed base 31 fixed to the inner wall of the five-axis machining center 2, a bearing 32 mounted on the fixed base 31, a rotating shaft 33 rotatably connected to the bearing 32, a mounting part 34 mounted on the side of the rotating shaft 33 and detachably mounted on the quick-change additive head mechanism 1, and a rotating cylinder 35 mounted on the fixed base 31 to drive the rotating shaft 33 to rotate. In this embodiment, a zero-point quick-change rivet 11a is provided on the side wall of the main support 11 of the quick-change additive head mechanism 1, and a zero-point positioning ring 34a adapted to the zero-point quick-change rivet 11a is provided on the side wall of the mounting part 34. In actual use, the rotating... Cylinder 35 drives rotary shaft 33 to rotate 90° to the left and reset. When the spindle 21 of the five-axis machining center 2 is connected to the quick-change tool holder 13 of the quick-change additive head mechanism 1, the zero-point quick-change pull pin 11a is disengaged from the zero-point positioning ring 34a, so that the quick-change additive head mechanism 1 is separated from the rotary mechanism 3 and connected to the spindle 21 of the five-axis machining center 2 for additive processing. When the quick-change additive head mechanism 1 is put back on the rotary mechanism 3, the spindle 21 of the five-axis machining center 2 drives the quick-change additive head mechanism 1 to move to the position of the rotary mechanism 3, and the zero-point quick-change pull pin 11a is reinserted into the zero-point positioning ring 34a, so that the quick-change additive head mechanism 1 is mounted on the rotary mechanism 3.
