It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0022] In one embodiment of this utility model, such as Figure 1-5As shown, a double-sided milling device is provided, including: a platform 1, a workpiece positioning mechanism 2, two sets of milling cutter assemblies 3, and a drive assembly 4. The platform 1 serves as a support base; the workpiece positioning mechanism 2 is disposed on the platform 1 for clamping and fixing the workpiece to be machined; the two sets of milling cutter assemblies 3 are respectively disposed at both ends of the workpiece for milling both sides of the workpiece; the drive assembly 4 is connected to both sets of milling cutter assemblies 3, and can independently drive each set of milling cutter assemblies 3 to perform linear movement along the X-axis, the milling device axis, and the Z-axis of the workpiece, thereby adjusting the relative position between the milling cutter assemblies 3 and the workpiece to adapt to the double-sided milling requirements of workpieces of different specifications.

[0023] The double-sided milling device provided by this utility model, by setting two sets of milling cutter assemblies 3 and matching them with independently driveable X-axis milling devices and Z-axis drive assemblies 4, allows the two sets of milling cutters to independently process both sides of the workpiece and flexibly adjust their positions, eliminating the need to repeatedly flip the workpiece, thereby shortening the processing time; at the same time, the workpiece positioning mechanism 2 can stably clamp the workpiece, effectively avoiding displacement during the processing, thus ensuring the accuracy of double-sided milling, greatly improving the overall efficiency of milling, and avoiding the accuracy deviation that may occur due to flipping.

[0024] Preferably, the workpiece positioning mechanism 2 includes a positioning base 201, a cylinder 202, and a pressure rod 204, wherein: the positioning base 201 is disposed on the platform 1, and the side and top surfaces of the positioning base 201 are configured as positioning planes adapted to the bottom surface of the workpiece; the cylinder 202 is fixedly installed on the side of the positioning base 201, and the output end of the cylinder 202 moves repeatedly along the Z-axis direction; the two ends of the pressure rod 204 extend to the upper sides of the workpiece on the positioning base 201, forming a pressing and covering range for the workpiece, and the pressure rod 204 is installed at the output end of the cylinder 202. (Supplementary usage process and advantages.)

[0025] When it is necessary to position the workpiece, the workpiece is first placed on the positioning plane of the positioning base 201. Since the shape of the positioning plane is adapted to the bottom surface of the workpiece, the placement accuracy of the workpiece can be initially guaranteed. Then, the cylinder 202 is activated, and the output end of the cylinder 202 is controlled to move downward along the Z-axis, so that the pressure rod 204 presses on the workpiece, thereby achieving stable holding of the workpiece.

[0026] The positioning plane of the positioning base 201 can quickly and accurately perform preliminary positioning of the workpiece, improving the efficiency of workpiece installation. By adjusting the stroke of the cylinder 202 and the position of the pressure rod 204, reliable positioning of various types of workpieces can be achieved, greatly enhancing the adaptability of the double-sided milling device to different workpieces.

[0027] In this embodiment, the drive assembly 4 includes a drive X-axis assembly 401, a drive milling device shaft assembly 402, and a drive Z-axis assembly 403, wherein: the output end of the drive X-axis assembly 401 is connected to the drive milling device shaft assembly 402 for transmission; the fixed end of the drive Z-axis assembly 403 is mounted on the output end of the drive milling device shaft assembly 402; and the output end of the drive Z-axis assembly 403 is connected to the milling cutter assembly 3 for transmission.

[0028] When machining a workpiece is required, the workpiece is first securely clamped onto the stage 1 by the workpiece positioning mechanism 2. Then, according to the workpiece specifications and machining requirements, the drive X-axis assembly 401, the drive milling device shaft assembly 402, and the drive Z-axis assembly 403 are operated respectively. The drive X-axis assembly 401 moves the drive milling device shaft assembly 402 along the X-axis direction, which in turn moves the drive Z-axis assembly 403 along the milling device axis direction. The drive Z-axis assembly 403 directly moves the milling cutter assembly 3 along the Z-axis direction. Through the coordinated movement of these three axes, the relative position between the milling cutter assembly 3 and the workpiece can be precisely adjusted, allowing the milling cutter assembly 3 to accurately reach the part of the workpiece that needs machining. This enables flexible movement of the milling cutter assembly 3 in three-dimensional space, meeting the machining needs of workpieces of different shapes and sizes, and greatly improving the versatility and applicability of the device.

[0029] Further, the drive X-axis assembly 401 includes an X-axis slide rail 411 extending along the X-axis direction, a sliding block 412, an annular belt 413, and an X-axis drive motor 414 for driving the annular belt 413 to rotate, wherein: the X-axis slide rail 411 and the X-axis drive motor 414 are both disposed on the platform 1, the sliding block 412 is slidably disposed on the X-axis slide rail 411, one side of the sliding block 412 is fixedly connected to the drive milling device shaft assembly 402, and the other side of the sliding block 412 is connected to the X-axis drive motor 414 through the annular belt 413.

[0030] During operation, when the X-axis drive motor 414 starts, it drives the annular belt 413 to rotate. The annular belt 413 then drives the sliding block 412 to slide linearly along the X-axis slide rail 411. Since the sliding block 412 is fixedly connected to the drive milling device shaft assembly 402, the drive milling device shaft assembly 402 moves along the X-axis as the sliding block 412 moves. The annular belt 413 transmission method features smooth transmission and low noise, providing more precise and efficient X-axis drive for the double-sided milling device.

[0031] In this embodiment, a cable chain can be installed on the platform 1 and connected to the sliding block 412. This effectively protects the internal cables, preventing them from becoming entangled or worn during the reciprocating motion of the sliding block 412. The cable chain moves synchronously with the sliding block 412 on the X-axis slide rail 411, ensuring the stability of power and signal transmission and further improving the reliability and service life of the device.

[0032] Furthermore, the drive milling device shaft assembly 402 includes a milling device axial slide rail 421 extending along the milling device shaft direction, a fixed seat 422, a rotating gear 423, a spur gear 424 extending along the milling device shaft direction, and a milling device shaft drive motor 425 for driving the rotating gear 423 to rotate. The spur gear 424 and the milling device axial slide rail 421 are both mounted on the sliding block 412. The fixed seat 422 is slidably disposed on the milling device axial slide rail 421. The milling device shaft drive motor 425 is mounted on the fixed seat 422. The rotating gear 423 is mounted on the output shaft of the milling device shaft drive motor 425, and the spur gear 424 meshes with the rotating gear 423. (Supplementary usage process and advantages.)

[0033] When the milling device shaft drive motor 425 starts, it drives the rotating gear 423 to rotate. Since the spur gear 424 meshes with the rotating gear 423, the rotation of the rotating gear 423 causes the fixed seat 422 to slide linearly on the axial slide rail 421 of the milling device. Because both the spur gear 424 and the axial slide rail 421 are mounted on the sliding block 412, the fixed seat 422 can move along the milling device axial direction while the sliding block 412 moves in the X-axis direction, thus achieving flexible movement of the double-sided milling device in both the X and milling device directions. Through the meshing transmission of the gear and the spur gear 424, a precise transmission ratio can be achieved, ensuring the accuracy of the milling device's axial movement and improving the machining quality of the double-sided milling device. This structure is relatively compact, occupies less space, and makes the overall structure of the double-sided milling device more reasonable, facilitating installation and maintenance.

[0034] Furthermore, the driving Z-axis assembly 403 is composed of a slide table, which includes a Z-axis guide rail 431 extending along the Z-axis direction, a slider 432 that slides with the Z-axis guide rail, and a power component 433 for driving the slider 432 to move along the guide rail. The power component 433 and the Z-axis guide rail 431 are mounted on the fixed base 422, and the milling cutter assembly 3 is mounted on the slider 432. The slider 432 and the power component 433 are connected by a screw 434.

[0035] When the power component 433 is activated, it drives the screw 434 to rotate. Due to the connection between the slider 432 and the screw 434, and the sliding engagement between the slider 432 and the Z-axis guide rail 431, the rotation of the screw 434 is converted into linear movement of the slider 432 on the Z-axis guide rail 431. Since the power component 433 (such as a motor) and the Z-axis guide rail 431 are both mounted on the fixed base 422, and the milling cutter assembly 3 is mounted on the slider 432, when the fixed base 422 moves in the X and milling device directions, the milling cutter assembly 3 can also move in the Z-axis direction, thereby realizing the flexible movement of the double-sided milling device in the X, milling device, and Z directions. This allows the milling cutter assembly 3 to be precisely positioned and moved in three-dimensional space, greatly improving the processing range and flexibility of the double-sided milling device. At the same time, the screw 434 transmission has the characteristics of smooth transmission and high load-bearing capacity, which can ensure the stability and accuracy of movement in the Z-axis direction, further improving the processing quality of the double-sided milling device.

[0036] Preferably, the table 1 has a slot 5 extending along the X-axis on its surface, and the slot 5 is located below the milling cutter assembly 3. Some debris generated during machining will fall through the slot 5, preventing debris from accumulating on the table 1 surface and affecting workpiece placement and machining accuracy.

[0037] The double-sided milling device also includes a protective cover 6 mounted above the platform 1. The protective cover 6 covers the workpiece positioning mechanism 2, the two sets of milling cutter assemblies 3, and the drive assembly 4. In actual use, the protective cover 6 provides all-around protection. When the double-sided milling device is running, the generated debris is confined inside the protective cover 6 and will not fly around, effectively preventing debris from causing harm to the surrounding environment and operators.

[0038] Preferably, the milling cutter assembly 3 can be composed of a milling cutter 301 and a motor 302. The motor 302 provides a stable and powerful power output to the milling cutter, ensuring that the milling cutter can maintain a stable cutting force during high-speed rotation, thereby effectively improving machining efficiency.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
