[0028] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the three-dimensional structure of a dual-spindle vertical machining center 100 provided in one embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of the three-dimensional structure of a dual-spindle vertical machining center 100 from another perspective. An embodiment of the present utility model provides a dual-spindle vertical machining center 100, which includes a frame 10, two spindles (not shown), two mounting frames 20 and two tool magazines 30. The frame 10 is used to be set on a support surface, and the frame 10 includes a front face 101 and two side faces 102 connected to both sides of the front face 101, and the side faces 102 are planes extending in the vertical direction. The two spindles are spaced apart on the front face 101 and can move in the vertical direction relative to the frame 10. The two mounting frames 20 are respectively provided on the two side faces 102. The mounting frame 20 includes a first end 21 and a second end 22 opposite to each other, the first end 21 is connected to the side face 102, and the second end 22 extends in a direction away from the side face 102. The two tool magazines 30 are respectively installed on the second ends 22 of the two mounting frames 20, and the two tool magazines 30 are respectively used to replace tools for the corresponding spindles.

[0029] Specifically, the frame 10 can be set on a supporting surface such as the ground or the surface of other equipment. The two spindles are spaced apart to reduce the risk of interference during processing. The two mounting frames 20 are respectively arranged on the two side surfaces 102 of the frame 10 to facilitate tool changing for the corresponding tool magazines 30. In this embodiment, the mounting frame 20 extends in a bent shape, that is, the second end 22 of the mounting frame 20 intersects at 90 degrees with the first end 21, and the second end 22 extends away from the side surface 102 and is located in front of the front side 101, so that the tool magazine 30 on the second end 22 can be close to the spindle to change the tool for the spindle.

[0030] By configuring the side surface 102 of the frame 10 as a plane extending in the vertical direction, the frame 10 has a high structural strength. Furthermore, the first end 21 of the mounting bracket 20 is connected to the side surface 102 of the frame 10, while the second end 22 of the mounting bracket 20 extends away from the side surface 102 and mounts the tool magazine 30. This provides sufficient space for tool changes in the tool magazine 30, while also reducing the volume requirement of the frame 10, thereby reducing space usage. Furthermore, the dual-spindle design effectively improves machining efficiency.

[0031] In one embodiment of this embodiment, a plurality of first guide rails 11 are provided on the front surface 101 of the frame 10. The two spindles are slidably engaged with corresponding first guide rails 11, and the first guide rails 11 extend parallel to the side surface 102. Specifically, the plurality of first guide rails 11 extend along the z-axis, enabling the spindles to move along the z-axis relative to the frame 10. This arrangement enables independent drive of the two spindles.

[0032] In one embodiment of this embodiment, there are four first guide rails 11, and each spindle is slidably engaged with two first guide rails 11. With this arrangement, both spindles have high guiding accuracy, which is conducive to improving machining accuracy.

[0033] In this embodiment, the frame 10 is provided with a connecting frame 13 , one end of the connecting frame 13 is slidably connected to the first guide rail 11 , and the other end of the connecting frame 13 is mounted with a main shaft.

[0034] In one embodiment of this embodiment, a first end 21 of the mounting frame 20 is provided with a strip-shaped hole 201 extending in a horizontal direction. The dual-spindle vertical machining center 100 further includes a fastener (not shown) that is inserted through the strip-shaped hole 201 and fixedly connected to the frame 10. Specifically, there are multiple fasteners for each of the strip-shaped holes 201, each of which is inserted through a corresponding strip-shaped hole 201 and fixedly connected to different positions of the frame 10. It will be understood that the presence of the strip-shaped hole 201 provides space for relative movement of the mounting frame 20 and the frame 10 in the horizontal direction, thereby facilitating adjustment of the relative position of the tool magazine 30 and the frame 10.

[0035] In this embodiment, the plurality of strip holes 201 extend along the y-axis direction to facilitate adjustment of the relative position of the tool magazine 30 and the frame 10 in the y-axis direction. The tool magazine 30 is a disc-type tool magazine that can accommodate more tools to meet various processing requirements.

[0036] In one embodiment of this embodiment, a dual-spindle vertical machining center 100 includes a worktable 40 mounted on the machine tool and movable horizontally relative to the machine tool. The worktable 40 is used to support a workpiece. Specifically, the worktable 40 can move along a single axis or multiple axes relative to the machine tool along the horizontal plane. It will be appreciated that the dual-spindle design, combined with the movable worktable 40, enables simultaneous machining of two workpieces, thereby improving machining efficiency.

[0037] In one embodiment of this embodiment, a dual-spindle vertical machining center 100 includes an x-axis drive mechanism 50 and a y-axis drive mechanism 60. The x-axis drive mechanism 50 drives the worktable 40 to move along the x-axis, while the y-axis drive mechanism 60 drives the worktable 40 to move along the y-axis. The x-axis is the direction in which the two spindles are arranged. This arrangement improves the efficiency of movement of the worktable 40 relative to the frame 10, thereby improving machining efficiency.

[0038] In one embodiment of this embodiment, the x-axis drive mechanism 50 includes a translation stage 51 and an x-axis drive member 52. The translation stage 51 is slidably mounted on the frame 10 along the y-axis. The y-axis drive mechanism 60 can drive the translation stage 51 to move relative to the frame 10 along the y-axis. The worktable 40 is slidably mounted on the translation stage 51 along the x-axis. The x-axis drive member 52 is mounted on the translation stage 51 and can drive the worktable 40 to move relative to the translation stage 51 along the x-axis. This arrangement enables the worktable 40 to move simultaneously along the y-axis and the x-axis, further improving the movement efficiency of the worktable 40 and thereby further improving processing efficiency.

[0039] In one embodiment of this embodiment, the translation stage 51 is provided with a second guide rail 511 extending along the x-axis. The worktable 40 slidably engages with the second guide rail 511, and the second guide rail 511 protrudes relative to the two side surfaces 102 of the translation stage 51 in the x-axis direction. This arrangement can increase the travel range of the worktable 40 in the x-axis direction, facilitating the processing of large workpieces.

[0040] In one embodiment of this embodiment, the frame 10 is provided with a plurality of third guide rails 12 extending along the y-axis direction, and the translation stage 51 slidably engages with the plurality of third guide rails 12. Specifically, there are two third guide rails 12, and the translation stage 51 slidably engages with the two third guide rails 12 to improve the guiding accuracy of the worktable 40 in the y-axis direction.

[0041] In one embodiment of this embodiment, the two tool magazines 30 are symmetrical along a vertical plane, and the two spindles are symmetrical along a vertical plane. This arrangement is beneficial to reducing mold opening costs and improving processing accuracy.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
