[0038] The lifting drive assembly 1 drives the lifting platform 2 to perform lifting movements, so that the upper guide rail 22 or the lower guide rail 23 is aligned with the machine base guide rail 61. After alignment, the upper workbench 3 or the lower workbench 4 enters the front machine base 6 along the machine base guide rail 61 through the feeding mechanism 5.

[0039] In this embodiment, the lifting drive assembly 1 includes a hydraulic cylinder mounting frame 11, a hydraulic cylinder 12, a connecting plate 13, a first floating joint 14 and a second floating joint 15.

When the lower workbench 4 is in the initial position, the second connecting groove 421 is limited and engaged with the lower lifting guide block 53.

[0043] When the upper workbench 3 needs to be transported to the front base 6 for operation, the lifting drive assembly 1 drives the lifting platform 2 to descend, and the first chain connector 32 descends simultaneously with the upper workbench 3. At this time, the first chain connector 32 leaves the upper lifting guide block 52 and hooks onto the workbench connector 56.

When the first chain connector 32 hooks the workbench connector 56, the upper guide rail 22 is aligned with the machine base guide rail 61. At this time, the sprocket 54 can be driven to drive the chain 55 to rotate. The workbench connector 56 will drag the first chain connector 32 to make the upper workbench 3 enter the front machine base 6 along the machine base guide rail 61 for operation. After the operation is completed, the workbench connector 56 pushes the first chain connector 32 to make the upper workbench 3 return to the lifting platform 2.

[0044] When the lower workbench 4 needs to be transported to the front machine base 6 for operation, the lifting drive assembly 1 drives the lifting platform 2 to move upward, and the second chain connector 42 rises simultaneously with the lower workbench 4. At this time, the second chain connector 42 leaves the lower lifting guide block 53 and hooks the workbench connector 56. At the same time, the first chain connector 32 of the upper workbench 3 rises with the lifting platform 2. The first chain connector 32 will be limited and engaged with the upper lifting guide block 52. At this time, the upper workbench 3 returns to its initial position. When the second chain connector 42 hooks the workbench connector 56, the lower guide rail 23 is aligned with the machine base guide rail 61. At this time, the sprocket 54 can be driven to drive the chain 55 to rotate. The workbench connector 56 will drag the second chain connector 42, allowing the lower workbench 4 to enter the front machine base 6 along the machine base guide rail 61 for operation.

[0045] The utility model relates to a hydraulic lifting table exchange device. This device avoids the problem of reduced cutting effect caused by a large Z-axis stroke when the cutting head cuts materials on the lower worktable 4. In this device, the lifting table 2 is controlled to rise or fall by a lifting drive assembly 1, thereby aligning the upper guide rail 22 or the lower guide rail 23 with the machine base guide rail 61. After alignment, the upper worktable 3 or the lower worktable 4 is fed along the machine base guide rail 61 via a feeding mechanism 5 onto the front machine base 6, thereby completing the operation of the upper worktable 3 and the lower worktable 4 at the same horizontal height, achieving consistent cutting effects on the two worktables and ensuring product quality.
