[0028] See also Figure 1 and Figure 2 , Figure 1 1 is a schematic diagram of the three-dimensional structure of a multi-spindle machining center 100 provided by an embodiment of the present invention; Figure 2 yes Figure 1A schematic diagram of the three-dimensional structure of the first mounting frame 21, the second mounting frame 31, the third mounting frame 41, the first connecting frame 61, the second connecting frame 62, the third connecting frame 63 and a part of the frame 10 of the multi-spindle machining center 100. An embodiment of the utility model provides a multi-spindle machining center 100, which includes a frame 10, a workbench 11, a first processing assembly 20 and a second processing assembly 30. The frame 10 is used to be set on a support surface. The first processing assembly 20 includes a first mounting frame 21 and a first spindle 22, and the first spindle 22 is mounted on the first mounting frame 21. The first mounting frame 21 is set on the frame 10 and can drive the first spindle 22 to move in the vertical direction relative to the frame 10. The second processing assembly 30 includes a second mounting frame 31 and a second spindle 32, and the second spindle 32 is mounted on the second mounting frame 31. One end of the second mounting frame 31 is connected to the frame 10 and is relatively close to the first mounting frame 21. The other end of the second mounting frame 31 is mounted with a second spindle 32 and is relatively far away from the first mounting frame 21. The workbench 11 is disposed on the frame 10 and can move horizontally relative to the frame 10. The workbench 11 is used to support a workpiece.

[0029] Specifically, the frame 10 can be placed on a supporting surface such as the ground or the surface of other equipment. In this embodiment, the second mounting frame 31 extends in a bent shape, so that one end of the second mounting frame 31 connected to the frame 10 is close to the first mounting frame 21 relative to the other end where the second spindle 32 is installed. There is sufficient distance between the second spindle 32 and the first spindle 22 installed in this way to reduce the risk of interference. At the same time, the installation of the second spindle 32 has lower requirements on the size of the frame 10, which can effectively reduce space occupancy and improve space utilization. Optionally, the number of workpieces carried on the workbench 11 corresponds to the number of spindles. In this embodiment, the workbench 11 can carry at least two workpieces for processing by the first spindle 22 and the second spindle 32 respectively. It should be noted that the vertical direction, i.e. Figure 1 The z-axis direction in the horizontal plane is the plane through which the y-axis and the x-axis directions pass. It is understood that the worktable 11 can drive the workpiece to move along a single axis or multiple axes on the horizontal plane to move the corresponding workpiece to the bottom side of the first spindle 22 and the second spindle 32 for processing.

[0030] By setting the second mounting frame 31 so that one end of the connecting frame 10 is close to the first mounting frame 21 relative to the other end where the second spindle 32 is installed, the second mounting frame 31 and the first mounting frame 21 are arranged compactly. At the same time, the second spindle 32 and the first spindle 22 can have a larger distance, thereby reducing the risk of interference and improving space utilization. At the same time, the first spindle 22 and the second spindle 32 are able to move in the vertical direction and the workbench 11 is able to move along the horizontal plane, which can realize the simultaneous processing of multiple workpieces, thereby effectively improving processing efficiency.

[0031] In one embodiment of this embodiment, the multi-spindle machining center 100 includes a third machining assembly 40, which includes a third mounting frame 41 and a third spindle 42. The third mounting frame 41 is located on the side of the first mounting frame 21 facing away from the second mounting frame 31. One end of the third mounting frame 41 is connected to the frame 10 and is relatively close to the first mounting frame 21. The other end of the third mounting frame 41 is mounted with the third spindle 42 and is relatively far away from the first mounting frame 21. This arrangement allows the third spindle 42 to perform machining operations simultaneously, which improves machining efficiency. Furthermore, because the end of the third mounting frame 41 connected to the frame 10 is closer to the end where the third spindle 42 is mounted, there is ample distance between the third spindle 42 and the first spindle 22, reducing the risk of interference. Furthermore, the installation of the third spindle 42 requires less space on the frame 10, further reducing space usage and improving space utilization.

[0032] In one embodiment of this embodiment, the third mounting bracket 41 is symmetrical with the second mounting bracket 31 along a vertical plane. This arrangement helps reduce mold making costs and ensures that the distances between the first spindle 22 and the second spindle 32, as well as the first spindle 22 and the third spindle 42 are the same, thereby improving machining accuracy.

[0033] In one embodiment of this embodiment, the multi-spindle machining center 100 includes a first tool magazine 51, a second tool magazine 52, and a third tool magazine 53, all of which are arranged on the frame 10. The first tool magazine 51 is arranged corresponding to the first spindle 22, the second tool magazine 52 is arranged corresponding to the second spindle 32, and the third tool magazine 53 is arranged corresponding to the third spindle 42. Specifically, the first tool magazine 51 is used to replace tools for the first spindle 22, the second tool magazine 52 is used to replace tools for the second spindle 32, and the third tool magazine 53 is used to replace tools for the third spindle 42. In this embodiment, the first tool magazine 51, the second tool magazine 52, and the third tool magazine 53 are all bamboo-hat-style tool magazines. In other embodiments, the first tool magazine 51, the second tool magazine 52, and the third tool magazine 53 can also be other types of tool magazines. By arranging the first tool magazine 51, the second tool magazine 52, and the third tool magazine 53 on the frame 10, it is convenient to replace tools for the first spindle 22, the second spindle 32, and the third spindle 42, respectively, which is conducive to improving machining efficiency.

[0034] In one embodiment of this embodiment, the multi-spindle machining center 100 includes a first connecting frame 61, a second connecting frame 62, and a third connecting frame 63. The first connecting frame 61 is disposed on the frame 10 and connected to the first tool magazine 51. One end of the second connecting frame 62 is connected to the frame 10 and is relatively close to the first connecting frame 61. The other end of the second connecting frame 62 is connected to the second tool magazine 52 and is relatively far away from the first connecting frame 61. One end of the third connecting frame 63 is connected to the frame 10 and is relatively close to the first connecting frame 61. The other end of the third connecting frame 63 is connected to the third tool magazine 53 and is relatively far away from the first mounting frame 21. Specifically, the first connecting frame 61 is located on the top side of the first mounting frame 21, the second connecting frame 62 is located on the top side of the second mounting frame 31, and the third connecting frame 63 is located on the top side of the third mounting frame 41. In this embodiment, the second connecting frame 62 and the third connecting frame 63 are symmetrically arranged along a vertical plane. The second mounting frame 31 and the third mounting frame 41 both extend in a curved shape. Such an arrangement can effectively reduce the space required for installing the first tool magazine 51, the second tool magazine 52 and the third tool magazine 53, and reduce the risk of interference.

[0035] In one embodiment of this embodiment, the multi-spindle machining center 100 includes an x-axis drive mechanism 70, which is mounted on a frame 10 and connected to a worktable 11. The x-axis drive mechanism 70 can drive the worktable 11 to move relative to the frame 10 along the x-axis, which is the direction in which the first, second, and third spindles 22, 32, and 42 are arranged. This arrangement improves machining efficiency.

[0036] In one embodiment of this embodiment, the multi-spindle machining center 100 includes a y-axis drive mechanism (not shown) disposed on the frame 10 and connected to the x-axis drive mechanism 70. The y-axis drive mechanism can drive the x-axis drive mechanism 70 to move the worktable 11 along the y-axis direction. This arrangement further improves machining efficiency.

[0037] In one embodiment of this embodiment, the x-axis drive mechanism 70 includes a translation stage 71 and an x-axis drive member 72. The translation stage 71 is slidably mounted on the frame 10 along the y-axis and is connected to the y-axis drive mechanism. The worktable 11 is slidably mounted on the translation stage 71 along the x-axis. The x-axis drive member 72 is mounted on the translation stage 71 and is connected to the worktable 11. This arrangement enables simultaneous movement of the worktable 11 along the y-axis and the x-axis, resulting in a high degree of movement efficiency for the worktable 11 and improving processing efficiency.

[0038] In one embodiment of this embodiment, the translation stage 71 is provided with a first guide rail 711 extending along the x-axis. The first guide rail 711 protrudes from both sides of the translation stage 71, and the worktable 11 and the first guide rail 711 slidably engage. Specifically, the ends of the first guide rail 711 protrude from opposite sides of the translation stage 71, respectively, to provide a greater x-axis travel, suitable for multi-workpiece machining. In this embodiment, there are two first guide rails 711, which provide more stable x-axis guidance.

[0039] In one embodiment of this implementation, the frame 10 is provided with a plurality of second guide rails 12 extending along the y-axis, and the translation stage 71 is slidably engaged with each of the plurality of second guide rails 12. Specifically, in this embodiment, the number of second guide rails 12 is four. This arrangement helps provide more stable guidance along the y-axis.
