[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] A double-head milling machine, such as Figure 1 and Figure 2 As shown, it includes a base 1, on which a workbench 2 for placing workpieces is movably arranged, two horizontal milling columns 3 are arranged on the base 1, and a horizontal milling head 5 is slidably connected to the horizontal milling column 3 along the vertical direction, and a vertical milling column 6 is also arranged on the base 1, and a vertical milling block 7 is slidably connected to the vertical milling column 6 along the vertical direction, and two vertical milling heads 8 are arranged on the vertical milling block 7, the two horizontal milling columns 3 are arranged along the X-axis direction, and the two vertical milling heads 8 are also arranged along the X-axis direction. By arranging two horizontal milling heads 5 and two vertical milling heads 8, when two workpieces with the same processing steps are installed on the workbench 2, they can be processed synchronously.

[0024] A first guide rail 9 is arranged on the horizontal milling column 3 in the vertical direction, and a horizontal milling block 4 is slidably connected to the first guide rail 9. The horizontal milling block 4 is driven to slide on the first guide rail 9 by a motor and a screw rod. The screw rod is connected to the output shaft of the motor. The screw rod passes through the horizontal milling block 4 and is threadedly connected to the horizontal milling block 4. When the motor drives the screw rod to rotate forward or reverse, the horizontal milling block 4 is driven to move upward or downward along the first guide rail 9. The horizontal milling head 5 is arranged on the horizontal milling block 4, thereby realizing up and down movement.

[0025] A second guide rail 10 is arranged on the vertical milling column 6 in the vertical direction, the vertical milling block 7 is slidably connected to the second guide rail 10, and the horizontal milling block 4 is driven by a motor and a screw rod to slide on the second guide rail 10, thereby realizing the up and down movement of the vertical milling head 8.

[0026] The horizontal milling head 5 is arranged toward the Y-axis direction, and the vertical milling head 8 is arranged toward the Z-axis direction, that is, the vertical direction. After the horizontal milling head 5 completes processing, the vertical milling head 8 performs side wall processing, so that two surfaces of the workpiece can be processed at one time. Since the horizontal milling head 5 and the vertical milling head 8 are respectively installed on their respective columns, they will not interfere with each other when moving, and the driving is more flexible. When one of them is driven, the other remains stationary, saving driving energy consumption.

[0027] The base 1 is slidably connected with a mounting plate 11 along the Y-axis direction, and the workbench 2 is slidably connected to the mounting plate 11 along the X-axis direction, so that the workbench 2 can move along the X-axis and Y-axis directions.

[0028] A third guide rail 12 is arranged on the base 1 along the Y-axis direction, the bottom of the mounting plate 11 is slidably connected to the third guide rail 12 through a slider, and the mounting plate 11 is driven to slide on the third guide rail 12 by a motor and a screw rod, and a fourth guide rail 13 is arranged on the mounting plate 11 along the X-axis direction, the bottom of the workbench 2 is slidably connected to the fourth guide rail 13 through a slider, and the workbench 2 is driven to slide on the fourth guide rail 13 by a motor and a screw rod. In this embodiment, the horizontal milling block 4, the vertical milling block 7, the mounting plate 11, and the workbench 2 are respectively driven by a motor and a screw rod, with the same driving mode, and the motor adopts a servo motor to accurately control the stroke.

[0029] The workbench 2 is rectangular in shape and extends along the X-axis direction. Two workpieces are clamped on the workbench 2 along the X-axis direction, so that the two horizontal milling heads 5 and the two vertical milling heads 8 can process the two workpieces synchronously. The spacing between the two horizontal milling heads 5 can be adjusted according to the installation position of the horizontal milling column 3, and the spacing between the two vertical milling heads 8 can be adjusted by replacing vertical milling blocks 7 of different specifications.

[0030] The horizontal milling column 3 and the vertical milling column 6 are respectively arranged on both sides of the workbench 2 along the X-axis direction. The two horizontal milling columns 3 are located on the left side, and the vertical milling column 6 is located on the right side, making the layout more reasonable and less likely to interfere with each other when performing horizontal milling and vertical milling respectively.

[0031] In this embodiment, the horizontal milling head 5 and the vertical milling head 8 are both rotated by belt drive. In other embodiments, the horizontal milling head 5 and the vertical milling head 8 can also be rotated by gear drive or direct motor drive.

[0032] The working process of the utility model is as follows:

[0033] The two workpieces are clamped at corresponding positions of the workbench 2 along the X-axis direction. The horizontal milling head 5 processes the workpiece first. The workbench 2 drives the workpiece to move along the X-axis and Y-axis directions, and the horizontal and vertical heads move along the Z-axis direction. After the horizontal milling head 5 completes the processing, the vertical milling head 8 performs side wall processing to achieve synchronous processing of the two workpieces. Two surfaces can be processed in one clamping, saving the workpiece clamping steps.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
