Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool processing technology, and in particular to a new type of flip-plate milling equipment suitable for ultra-large stroke moving column. Background Technology

[0002] With the rapid development of my country's aviation industry, aluminum alloy parts in the aviation field are characterized by high removal rates, large dimensions, and thin-walled structures. Existing conventional machining centers struggle to meet the high-efficiency, high-precision machining requirements. Traditional vertical gantry machining centers suffer from poor chip removal, leading to secondary chip processing and poor heat dissipation, resulting in loss of machining accuracy. In contrast, flip-type horizontal machining centers offer significant advantages in this area. Currently, flip-type machining centers with moving column structures suffer from insufficient rigidity due to the bidirectional movement of the column and the suspension of the tilting head, resulting in reduced machining accuracy. Furthermore, the column size is also constrained. Therefore, this invention proposes a new configuration of flip-type milling equipment with a moving column suitable for ultra-large strokes, solving the problems of insufficient rigidity and low machining accuracy in large-size flanging machining centers.

[0016] Example 1 like Figures 1 to 4 As shown, the present invention discloses a structural diagram of a first embodiment of a new type of flip-plate milling machine with ultra-large stroke moving column, which includes: a host 1 and a worktable exchange system 2; The main unit 1 includes a bed 10, a support frame 11, a movable column mechanism 12, and a spindle mechanism 13; The support frame 11 is mounted on the bed 10; The moving column mechanism 12 is installed on the side of the bed 10 and the support frame 11 facing the workbench exchange system 2. The moving column mechanism 12 can move along the X-axis. The main shaft mechanism 13 is mounted on the moving column mechanism 12; The workbench exchange system 2 includes a workbench pushing device 20, a workbench flipping device 21, and a workbench fixing device 22. The workbench pushing device 20 is located on one side of the workbench tilting device 21 and is used to realize the conveying of the workbench 8 between the loading and unloading station and the workbench tilting station. The workbench tilting device 21 is disposed between the workbench pushing device 20 and the workbench fixing device 22, and is used to drive the workbench 8 to tilt in the horizontal and vertical directions. The worktable fixing device 22 is disposed on the machining area side of the spindle mechanism 13 and is used to lock the worktable 8 when the worktable 8 is in a vertical position. The worktable fixing device 22 includes a worktable base 220 and a worktable fixing frame 221, and the worktable fixing frame 221 is disposed on the worktable base 220. The support frame 11 and the workbench fixing frame 221 are connected to each other by a connecting frame 3.

[0017] Specifically, in this embodiment, the main unit 1, the worktable tilting device 21, and the worktable fixing device 22 are all placed in a pit, and the worktable pushing device is placed on the ground. The main unit 1 includes a bed 10 arranged along the X-axis direction, a support frame 11 is provided on the bed 10, and a movable column mechanism 12 is installed on one side of the bed 10 and the support frame 11. The movable column mechanism 12 is located on the side of the bed 10 and the support frame 11 facing the worktable exchange system. The movable column mechanism 12 can move along the X-axis direction. A spindle mechanism 13 is installed on the movable column mechanism 12. The spindle mechanism 13 is a parallel spindle head assembly. The movable column mechanism can drive the parallel spindle head assembly to move in the X-axis direction to realize the processing of the workpiece. A table exchange system 2 is provided on one side of the main unit 1 (the side facing the parallel spindle head assembly). The table exchange system 2 includes a table pushing device 20 that can transfer the worktable 8 to the loading / unloading station and the table flipping station, a table flipping device 21 that can flip the worktable to horizontal and vertical states, and a table fixing device 22 that locks the worktable when it is in the vertical state so that the parallel spindle head assembly can process the workpiece on the worktable 8. The table fixing device 22 includes a table base 220 arranged along the X-axis and a table fixing frame 221 arranged on the table base 220. The support frame 11 and the table fixing frame 221 are connected to each other by a connecting frame 3. The five-axis flip milling machining center disclosed in this embodiment enhances the overall structural rigidity of the machining center because the support frame of the main unit and the table fixing frame are connected by a connecting frame. This is beneficial to enhancing the dynamic rigidity of the spindle mechanism (parallel spindle head), ensuring machining stability, and improving machining accuracy. Meanwhile, since the worktable is in a vertical position when the machining center is in operation, it is easier to clean up cutting chips and avoid secondary processing of chips and workpiece deformation caused by heat.

[0018] Furthermore, the connecting frame 3 connects the upper two side walls of the support frame 11 and the workbench fixing frame 221.

[0019] Specifically, in this embodiment, two connecting frames are provided between the supporting frame and the workbench fixing frame, the two connecting frames are respectively located on both sides of the supporting frame (the workbench fixing frame), one end of each connecting frame is fixedly connected to the upper end of the side of the supporting frame facing the workbench fixing frame, and the other end of each connecting frame is fixedly connected to the upper end of the side wall of the workbench fixing frame. By providing two connecting frames, which connect the supporting frame and both sides of the upper end of the workbench fixing frame, the overall structural rigidity of the machining center can be further improved, thereby enhancing the dynamic stiffness of the spindle mechanism (parallel spindle head), ensuring machining stability and improving machining accuracy.

[0020] Further, the supporting frame 11 comprises first upright posts 110 oppositely arranged at two ends of the bed 10, an intermediate upright post 111 located between the two first upright posts 110, and a first cross beam 112 connecting the upper ends of the first upright posts 110 and the intermediate upright post 111. The workbench fixing frame 221 comprises two second upright posts 222 oppositely arranged at two ends of the workbench base 220, and a second cross beam 223 for connecting the upper ends of the two second upright posts 222.

[0021] Specifically, in this embodiment, the supporting frame 11 comprises two oppositely arranged first upright posts 110, an intermediate upright post 111 located between the two first upright posts 110, and a first cross beam 112 located at the upper end, the first upright posts, the intermediate upright post, the first cross beam and the bed body are fixedly connected to each other, Figure 1 the number of the intermediate upright posts is 1, forming a structure similar to a horizontally placed "ri" (Japanese character shaped like a sun divided by a middle horizontal line, which is two connected rectangles) structure. The "ri"-shaped supporting frame can ensure that the moving upright post still has high rigidity under the condition of large stroke (in the X-axis direction), thereby enhancing the dynamic stiffness of the spindle mechanism (parallel spindle head), ensuring machining stability and improving machining accuracy. The number of intermediate upright posts can be set to 1, 2 or more as required, which can not only increase the stroke, but also better improve the rigidity of the cross beam. For example, to increase the stroke, a second intermediate upright post can be added to form a "mu" (Chinese character shaped like three connected rectangles) structure, so as to better improve the rigidity of the cross beam. Meanwhile, in the present application, the cross beam is arranged behind the moving upright post, forming effective support for the structure of the moving upright post, and better improving the rigidity of the moving upright post mechanism. The workbench fixing frame 221 comprises oppositely arranged second upright posts 222 and a second cross beam 223 for connecting the upper ends of the two second upright posts 222, the two second upright posts 222, the second cross beam 223 and the workbench base 220 are sequentially fixedly connected together to form a structure similar to a "kou" (Chinese character shaped like a hollow rectangle) structure. The "kou"-shaped structure formed by the workbench fixing frame 221 can ensure the fixing rigidity of the workbench when it is in a vertical state, thereby ensuring machining stability and improving machining accuracy.

[0022] Further, the moving upright post mechanism 12 comprises a moving upright post 120 and a moving upright post transmission system 4; The upper and lower ends of the fixed side of the movable column 120 are respectively mounted on the bed 10 and the first crossbeam 112 via slide rail assemblies. The upper and lower ends of the fixed side of the movable column 120 are respectively provided with a set of movable column transmission system 4 that can drive the movable column 120 to move along the X-axis. Each set of moving column transmission system 4 includes a first moving column transmission servo motor 40, a second moving column transmission servo motor 41, a first moving column transmission reducer 42, a second moving column transmission reducer 43, a first gear 44, a second gear 45, and a rack 46. The rack 46 is fixed to the bed 10 or the first crossbeam 112 along the X-axis. The first moving column drive servo motor 40, the first moving column drive reducer 42 and the first gear 44 are connected in sequence and installed on the moving column 120. The second moving column drive servo motor 41, the second moving column drive reducer 43 and the second gear 44 are connected in sequence and installed on the moving column 120. The first gear 44 and the second gear 45 both mesh with the rack 46, and the first moving column drive servo motor 40 and the second moving column drive servo motor 41 rotate in opposite directions. The movable column 120 is a frame structure, and the parallel spindle head assembly is installed inside the frame of the movable column 120.

[0023] Specifically, in this embodiment, the moving column mechanism is a frame-type moving column structure, specifically including a frame-structured moving column. A parallel spindle head assembly is installed inside the frame-structured moving column. Both the upper and lower ends of the frame-structured moving column are connected to the bed 10 and the first crossbeam 112 via slide rail assemblies. The slide rail assembly includes a slider and slide rails. Slide rails are fixed along the X-axis on both the bed 10 and the first crossbeam 112. A slider is installed on the frame-structured moving column, allowing the moving column to move along the X-axis via the slide rail assembly. Both the upper and lower ends of the moving column 120 are equipped with... A set of moving column transmission systems 4 drives the moving column 120 to move along the X-axis. Each set of moving column transmission systems 4 includes a first moving column transmission servo motor 40, a second moving column transmission servo motor 41, a first moving column transmission reducer 42, a second moving column transmission reducer 43, a first gear 44, a second gear 45, and a rack 46. The upper and lower moving column transmission systems 4 synchronously drive the moving column mechanism, which can improve the movement stability of the moving column. Furthermore, the motor and reducer of the lower moving column transmission system are arranged behind the moving column, which can save space. In this way, the X-axis travel of the moving column is effectively increased; furthermore, when the main machine of the flip milling machine requires high dynamic processing, two sets of servo motors can be added to increase the transmission torque and improve the dynamic response; racks 46 are fixed along the X-axis on the bed 10 and the first crossbeam 112 respectively; the first moving column drive servo motor 40, the first moving column drive reducer 42 and the first gear 44 are sequentially connected and installed on the moving column 120; the second moving column drive servo motor 41, the second moving column drive reducer 43 and the second gear 44 are sequentially connected and installed on the moving column 120. Mounted on the moving column 120, the first gear 44 and the second gear 45 both mesh with the rack 46, and the first moving column drive servo motor 40 and the second moving column drive servo motor 41 rotate in opposite directions. Through the servo motor, reducer, gears and rack, the moving column can be driven to move along the X-axis to realize the processing of the workpiece. At the same time, since the first moving column servo motor and the second moving column servo motor rotate in opposite directions, the meshing gap of the gear and rack transmission can be eliminated, ensuring the movement accuracy of the moving column in the X-axis direction, thereby improving the processing accuracy.

[0024] Furthermore, in this embodiment, the parallel spindle head assembly includes an electric spindle 130, a spindle box 131, a first robotic arm assembly 132, a second robotic arm assembly 133, a third robotic arm assembly 134, and a spindle box transmission system 5; The spindle box 131 is installed in the frame of the movable column 120.

At the central exchange station, the worktable with the workpiece to be processed is pushed to the horizontally set flipping table via the worktable pushing component; 3. The flipping table fixes the worktable with the workpiece to be processed and drives the worktable to flip to a vertical state; 4. The main machine processes the workpiece to be processed on the worktable, and simultaneously, at the loading / unloading station, another worktable with the workpiece to be processed is transported to the central exchange station via the transverse exchange station; 5. The vertical exchange station will move the worktable located in the center... 6. After the workpiece to be processed is completed, the turnover table flips from a vertical state to a horizontal state, and the workpiece with the processed workpiece is pushed from the turnover table to the central turnover table by the workpiece pushing component; 7. At the central turnover table, the workpiece with the processed workpiece is transported to the loading and unloading station by the horizontal turnover table; 8. The workpiece with the workpiece to be processed, which is temporarily stored, is transported from the vertical turnover table to the central turnover table; 9. At the central turnover table, the workpiece with the workpiece to be processed is pushed to the horizontally set turnover table by the workpiece pushing component, and the above workpiece transport process is repeated in sequence.

[0035] This application incorporates a transverse exchange station, a longitudinal exchange station, a central exchange station, and a worktable pushing component. This allows the next workpiece to be processed to be temporarily stored at the longitudinal exchange station of the machining center during the workpiece processing process. This enables rapid worktable switching upon completion of processing, reducing worktable changeover time and improving machine tool processing efficiency.
