[0042] With reference to Figure 1 According to the first aspect of the embodiment of the application, the bearing module comprises a mounting seat 100, a first workbench 200, a second workbench 300, an x-axis driving mechanism 410 and a y-axis driving mechanism 420.

[0043] The first workbench 200 is movably arranged along the x-axis direction on the mounting seat 100; the second workbench 300 is movably arranged along the y-axis direction on the mounting seat 100; the x-axis driving mechanism 410 is drivingly connected to the mounting seat 100, for driving the mounting seat 100 to move along the x-axis direction; the y-axis driving mechanism 420 is drivingly connected to the mounting seat 100, for driving the mounting seat 100 to move along the y-axis direction.

[0044] It can be understood that the first workbench 200 and the second workbench 300 correspond to a machining mechanism 800 respectively, and the two machining mechanisms 800 can process the workpieces on the first workbench 200 and the second workbench 300 respectively. The x-axis driving mechanism 410 can drive the mounting seat 100 to move along the x-axis direction, and the y-axis driving mechanism 420 can drive the mounting seat 100 to move along the y-axis direction, so as to drive the first workbench 200 and the second workbench 300 on the mounting seat 100 to move in the x-axis direction and the y-axis direction relative to the machining mechanism 800. Since the first workbench 200 is movably arranged on the mounting seat 100 along the x-axis direction, when there is a machining error of the workpiece on the first workbench 200 or the workpiece on the second workbench 300 in the x-axis direction, resulting in inconsistent machining precision of the workpiece on the first workbench 200 and the workpiece on the second workbench 300, the relative position of the first workbench 200 and the second workbench 300 in the x-axis direction can be adjusted by moving the first workbench 200 along the x-axis direction, so that the position of the workpiece on the first workbench 200 and the workpiece on the second workbench 300 in the x-axis direction relative to the corresponding machining mechanism 800 is consistent, so as to ensure the machining precision of the workpiece on the first workbench 200 and the workpiece on the second workbench 300 is consistent. Then, the mounting seat 100 is driven by the x-axis driving mechanism 410 to move along the x-axis direction, so as to simultaneously compensate for the machining error of the workpiece on the first workbench 200 and the workpiece on the second workbench 300, and ensure the machining precision of the workpiece on the first workbench 200 and the workpiece on the second workbench 300 in the x-axis direction. Similarly, the second workbench 300 is movably arranged on the mounting seat 100 along the y-axis direction, so that when there is a machining error of the workpiece on the first workbench 200 or the workpiece on the second workbench 300 in the y-axis direction, resulting in inconsistent machining precision of the workpiece on the first workbench 200 and the workpiece on the second workbench 300, the relative position of the first workbench 200 and the second workbench 300 in the y-axis direction can be adjusted by moving the second workbench 300 along the y-axis direction, so that the position of the workpiece on the first workbench 200 and the workpiece on the second workbench 300 in the y-axis direction relative to the corresponding machining mechanism 800 is consistent, so as to ensure the machining precision of the workpiece on the first workbench 200 and the workpiece on the second workbench 300 is consistent. Then, the mounting seat 100 is driven by the y-axis driving mechanism 420 to move along the y-axis direction, so as to simultaneously compensate for the machining error of the workpiece on the first workbench 200 and the workpiece on the second workbench 300, and ensure the machining precision of the workpiece on the first workbench 200 and the workpiece on the second workbench 300 in the y-axis direction.

[0045] It can be understood that by moving the first workbench 200 relative to the mounting base 100 along the x-axis direction and moving the second workbench 300 relative to the mounting base 100 along the y-axis direction, the machining precision of the workpieces on the first workbench 200 and the second workbench 300 in the x-axis direction and the y-axis direction can be ensured to be consistent. Subsequently, the mounting base 100 can be driven by the x-axis driving mechanism 410 and the y-axis driving mechanism 420 to drive the first workbench 200 and the second workbench 300 to move along the x-axis direction and the y-axis direction, and the workpieces on the first workbench 200 and the second workbench 300 can be compensated in the x-axis direction and the y-axis direction to ensure the machining precision of the workpieces.

[0046] In addition, in some other embodiments, when the workpieces on the first workbench 200 have machining errors in the x-axis direction and the workpieces on the second workbench 300 have no machining errors in the x-axis direction, only the first workbench 200 can be moved along the x-axis direction to compensate for the workpieces on the first workbench 200. Similarly, when the workpieces on the second workbench 300 have machining errors in the y-axis direction and the workpieces on the first workbench 200 have no machining errors in the y-axis direction, only the second workbench 300 can be moved along the y-axis direction to compensate for the workpieces on the second workbench 300.

[0047] It should be understood that since the first workbench 200 and the second workbench 300 are both arranged on the mounting base 100, the first workbench 200 and the second workbench 300 will move synchronously along the x-axis direction and the y-axis direction under the driving of the x-axis driving mechanism 410 and the y-axis driving mechanism 420.

[0048] Regarding the manner in which the first workbench 200 moves relative to the mounting base 100 along the x-axis direction:

[0050] It can be understood that the first workbench 200 is driven by the x-axis execution mechanism 510 to move along the x-axis direction to automatically adjust the position of the first workbench 200 in the x-axis direction.

[0051] Specifically, referring to Figure 1The specific structure of the x-axis actuating mechanism 510 is as follows: the x-axis actuating mechanism 510 comprises a first motor 511, a first screw rod 512, a first screw nut 513, and a first screw nut seat 514.

The first screw nut 513 can move in the extension direction of the first screw rod 512, i.e., the x-axis direction, to drive the first screw nut seat 514 and the first workbench 200 to move in the x-axis direction. It should be understood that the first motor 511 is arranged on one side of the mounting seat 100 in the y-axis direction, and the first screw rod 512 is located beside the mounting seat 100, so that the x-axis actuating mechanism 510 can be installed using the space on one side of the first workbench 200 in the y-axis direction, thereby saving the occupied space of the x-axis actuating mechanism 510.

[0053] It should be noted that the motor of the x-axis driving mechanism 410 is located on one side of the mounting seat 100 in the x-axis direction, and the slide rails of the x-axis driving mechanism 410 extend to both sides of the mounting seat 100 in the x-axis direction. Therefore, the first motor 511 and the first screw rod 512 are arranged on one side of the mounting seat 100 in the y-axis direction, which can avoid interference with the x-axis driving mechanism 410 and better utilize the installation space. Moreover, the first workbench 200 moves in the x-axis direction, and the first motor 511 is arranged on one side of the mounting seat 100 in the y-axis direction, which can avoid interference with the first workbench 200. Furthermore, one side of the mounting seat 100 in the y-axis direction is the front side of the machine tool to which the bearing module of the present application is applied, and the first motor 511 is arranged on one side of the mounting seat 100 in the y-axis direction, which can facilitate the installation and maintenance of the first motor 511.
