[0023] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the present application will be described in further detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. In addition, the present application can also be implemented in other ways different from those described herein, and therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.
[0024] One specific embodiment of the present application is shown in Figures 1-3 A double-spindle double-five-axis vertical machining center, comprising a bed frame 1, a rotary worktable 2 and two groups of five-axis motion assemblies.
[0025] The bed frame 1 comprises an operation platform and a rail mounting frame; the rail mounting frame comprises a first side, a second side and a top surface; the operation platform is arranged at the bottom between the first side and the second side, and the first side and the second side are both perpendicular to the operation platform; the first side, the second side and the top surface are symmetrically provided with two groups of rails, and the rails comprise Z-axis guides and X-axis guides; two groups of Z-axis guides are symmetrically arranged on the first side and the second side, respectively; the Z-axis guides are perpendicular to the operation platform; the top surface is arranged at the top between the first side and the second side, and the top surface is symmetrically provided with two groups of X-axis guides; the X-axis guides are parallel to the operation platform.
[0026] The rotary worktable 2 is arranged at the center of the bed frame 1, and the workpiece 3 to be machined is installed on the rotary worktable 2 by a clamp.
[0027] The two groups of five-axis motion assemblies are arranged on the rails.
[0028] The five-axis motion assembly comprises X-axis motion components (4-1) (4-2), Y-axis guides, Y-axis motion components (5-1) (5-2), Z-axis guides, Z-axis motion components (6-1) (6-2) and C-axis orthogonal swing heads (7-1) (7-2), A-axis orthogonal swing heads (8-1) (8-2), machine tool spindles (9-1) (9-2) and machining tools (10-1) (10-2).
[0029] It can be understood that the C-axis is an axis rotating around the Z-axis, and the A-axis is an axis rotating around the X-axis.
[0030] Among the above motion components:
[0031] The two ends of the X-axis motion components (4-1) (4-2) slide on the X-axis guides through the sliders, and are driven by X-axis servo driving devices.
[0032] Two sets of Y-axis guide rails are set inside the X-axis motion components (4-1) and (4-2); the Y-axis motion components (5-1) and (5-2) slide on the Y-axis guide rails by sliders and achieve center of gravity drive by Y-axis servo drive device.
[0033] The Y-axis motion components (5-1) and (5-2) each have four Z-axis guide rails arranged in a square layout. The Z-axis motion components (6-1) and (6-2) slide on the Z-axis guide rails via sliders and are driven by the Z-axis servo drive device.
[0034] A C-axis orthogonal swivel head (7-1)(7-2) is installed at the end of the Z-axis motion component (6-1)(6-2). An A-axis orthogonal swivel head (8-1)(8-2) is installed on the C-axis orthogonal swivel head (7-1)(7-2). A machine tool spindle (9-1)(9-2) is set on the A-axis orthogonal swivel head (8-1)(8-2). A machining tool (10-1)(10-2) for symmetrical machining of the workpiece to be machined is set at the end of the machine tool spindle (9-1)(9-2).
[0035] It is understandable that the two machining tools (10-1) and (10-2) perform symmetrical machining on both sides of the workpiece.
[0036] It also includes a CNC device 11, wherein each axis of the bed frame 1 is driven by a servo drive amplifier and a feed servo motor, and is controlled by the CNC device 11. The CNC device 11 is used to input the control CNC program and control the five-axis motion components on both sides respectively, so as to realize the synchronous symmetrical milling of the machine tool spindle (9-1)(9-2) on the workpiece 3 to be machined.
[0037] The bed frame is a fully enclosed symmetrical structure, featuring high rigidity and stability. The five-axis motion components mounted on both sides of the bed frame employ the same structure.
[0038] The CNC device 11 can perform linkage control on the five-axis motion devices on both sides to realize the synchronous symmetrical milling of the workpiece 3 to be processed on both sides.
[0039] The dual-spindle, dual-five-axis linkage high-speed and high-efficiency vertical machining center provided by this utility model, such as Figure 1As shown, symmetrical double-spindle synchronous milling machining of the workpiece to be machined can be realized. The workpiece to be machined 3 is fixed on the rotary worktable 2 by the clamp, the machine tool main shafts (9-1) and (9-2) are respectively moved in the axial direction of the machine tool X, Y and Z axes by the axial movement devices of the machine tool X, Y and Z axes and the C-axis orthogonal swing head and the A-axis orthogonal swing head, the linear movement of the pair of machine tool main shafts (9-1) and (9-2) in the axial direction of the machine tool X, Y and Z axes and the rotary movement of the pair of machine tool main shafts (9-1) and (9-2) around the Z and X axes are realized, and the double five-axis linkage machining of the workpiece to be machined 3 is realized. The numerical control device 11 controls the numerical control machining program to realize the double five-axis linkage movement of the machine tool, and then realizes the machine tool double-side spindle synchronous symmetrical milling machining of the workpiece to be machined 3.
[0040] For the rotary workpiece with the rotary array feature, since the machining can be simultaneously performed at both ends of the workpiece and the cutting forces applied by the cutters to both ends of the workpiece are offset, the machining deformation of the workpiece can be reduced, and the machining quality and machining efficiency of the workpiece are improved. For some workpieces with non-fully central symmetrical rotary features, for example, the blades on the blade disc are usually an odd number, i.e., the workpiece is a non-fully central symmetrical workpiece, the double-spindle double five-axis linkage high-speed and high-efficiency vertical machining center disclosed by the utility model can also offset the cutting forces on both sides of the blade disc to a certain extent during the machining process, so that the deformation caused by the machining is reduced.
[0041] The above merely describes the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
