[0030] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. In addition, the present invention can also be implemented in other ways different from those described herein, and therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.
[0031] A specific embodiment of the present invention, as Figures 1 - 3 As shown, a double-linkage high-speed and high-efficiency vertical processing machine tool includes a bed frame 1, a rotary worktable 2 and two sets of five-axis motion components.
[0032] See also Figure 1 The bed frame 1 includes an operating platform and a track mounting frame; the track mounting frame includes a first side surface, a second side surface and a top surface; the operating platform is arranged at the bottom between the first side surface and the second side surface, and the first side surface and the second side surface are both perpendicular to the operating platform; two groups of tracks are symmetrically arranged on the first side surface, the second side surface and the top surface, and the tracks include Z-axis guide rails and / or X-axis guide rails; two groups of Z-axis guide rails are symmetrically arranged on the first side surface and the second side surface; the Z-axis guide rail is perpendicular to the operating platform; the top surface is arranged at the top between the first side surface and the second side surface, and two groups of X-axis guide rails are symmetrically arranged on the top surface; the X-axis guide rail is parallel to the operating platform.
[0033] The rotary table 2 is arranged at the center of the bed frame 1 , and the workpiece 3 to be processed is mounted on the rotary table 2 through a fixture.
[0034] Both sets of five-axis motion components are arranged on tracks.
[0035] The five-axis motion assembly includes an X-axis motion component 4-1, a Y-axis guide, a Y-axis motion component 5-1, a Z-axis guide, a Z-axis motion component 6-1, a C-axis orthogonal swing head 7-1, an A-axis orthogonal swing head 8-1, a machine tool spindle 9-1 and a machining tool 10-1.
[0036] 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.
[0037] Among the above moving parts:
[0038] Both ends of the X-axis moving component 4-1 slide on the X-axis guide rails through sliders and are driven by an X-axis servo drive device.
[0039] Two sets of Y-axis guide rails are arranged inside the X-axis moving component 4-1; the Y-axis moving component 5-1 slides on the Y-axis guide rails through a slider, and realizes center of gravity driving through a Y-axis servo drive device.
[0040] There are four Z-axis guide rails inside the Y-axis moving component 5-1 in a square layout. The Z-axis moving component 6-1 slides on the Z-axis guide rails through a slider and realizes center of gravity drive through a Z-axis servo drive device.
[0041] A C-axis orthogonal swing head 7-1 is installed at the end of the Z-axis moving component 6-1, an A-axis orthogonal swing head 8-1 is installed on the C-axis orthogonal swing head 7-1, a machine tool spindle 9-1 is set on the A-axis orthogonal swing head 8-1, and a processing tool 10-1 for performing symmetrical processing on both sides of the workpiece to be processed is set at the end of the machine tool spindle 9-1.
[0042] It can be understood that the two machining tools 10 - 1 perform symmetrical machining on the workpiece.
[0043] It also includes a numerical control device 11, and each axis of the machine tool is driven by a servo drive amplifier and a feed servo motor, and is controlled by the numerical control device 11. The numerical control device 11 is used to input a numerical control program and control the five-axis motion components on both sides respectively, so as to realize synchronous symmetrical milling of the machine tool spindle 9-1 on the workpiece 3 to be processed.
[0044] The bed structure frame is a fully enclosed symmetrical structure with high rigidity and high stability. The five-axis motion components installed on both sides of the bed structure frame adopt the same structure.
[0045] The numerical control device 11 can respectively perform linkage control on the five-axis motion devices on both sides to achieve bilateral synchronous symmetrical milling of the workpiece 3 to be processed.
[0046] The present invention provides a dual-spindle dual-five-axis linkage high-speed and high-efficiency vertical machining center, such as Figure 1 As shown, symmetrical dual-spindle synchronous milling of the workpiece to be processed can be achieved. The workpiece 3 to be processed is fixed on the rotary table 2 by a fixture, and the machine tool spindle 9-1 realizes a pair of machine tool spindles 9-1 in the X, Y, and Z axis directions and rotational motion around the Z and X axes through the machine tool X, Y, and Z axis axial motion components and the C-axis orthogonal swing head and the A-axis orthogonal swing head, respectively, to achieve the dual five-axis linkage processing of the workpiece 3 to be processed. The numerical control device 11 controls the numerical control processing program to realize the dual five-axis linkage motion of the machine tool, thereby realizing the synchronous symmetrical milling of the machine tool double-side spindles of the workpiece 3 to be processed.
[0047] For rotating workpieces with rotating array features, since both ends of the workpiece can be processed simultaneously and the cutting force applied by the tool to both ends of the workpiece can be offset, the processing deformation of the workpiece can be reduced and the processing quality and efficiency of the workpiece can be improved. For some workpieces whose rotating features are not completely centrosymmetric, for example, the blades on the blade disk are usually an odd number, that is, they are not completely centrosymmetric workpieces, the dual-spindle dual five-axis linkage high-speed and efficient vertical machining center proposed by the present invention can also offset the cutting force on both sides of the blade disk to a certain extent during the machining process, thereby reducing the deformation caused by machining. Therefore, in order to achieve synchronous machining of rotating workpieces with odd or even numbers of rotating array features.
