The driving assembly 63 includes a first guide rod 631 fixed to the top of the bed 1, a first threaded rod 632 rotatably mounted on the top of the bed 1, a third motor 633 fixed to the top of the bed 1 and used to drive the first threaded rod 632, a driving block 634 sleeved on the first threaded rod 632 and threadedly connected to the first threaded rod 632, a first connecting rod 635 hinged to the top of the driving block 634, and a second connecting rod 636 hinged to the top of the bed 1. And a third connecting rod 637 hinged to the top of the bed 1 and parallel to the second connecting rod 636, the first guide rod 631 passes through the driving block 634 and slides with the driving block 634, the first threaded rod 632 passes through the driving block 634 and is threadedly connected to the driving block 634, the end of the first connecting rod 635 away from the driving block 634 is hinged to the second connecting rod 636, the end of the second connecting rod 636 away from the bed 1 is hinged to the bottom of the operating block 616, and the end of the third connecting rod 637 away from the bed 1 is hinged to the bottom of the rectangular frame 611.

[0048] In this embodiment, a second threaded rod 103 is hinged on the top of the bed 1, a second guide rod 104 and a fourth motor 105 for driving the second threaded rod 103 to rotate are fixed on the top of the bed 1, the second guide rod 104 passes through the mounting frame 2 and slides with the mounting frame 2, the second threaded rod 103 passes through the mounting frame 2 and is threadedly connected to the mounting frame 2, and the first motor 21, the second motor 612, the third motor 633 and the fourth motor 105 are all electrically connected to the control center of the five-axis linkage turning and milling compound machining device.

[0049] The operating principle of a five-axis linkage turning and milling compound machining device in this embodiment is: when the mounting block 4 is installed in the placement groove 31, the connecting block 53, under the elastic force of the first spring 52, makes the hook block 55 hook with the hook groove 32 and maintain a tight connection state, thereby ensuring the stability of the mounting block 4 and the turning tool 33 on the mounting block 4 during use. When processing the same workpiece and requiring multiple turning tools 33, the turning tool 33 on the tool holder 3 needs to be disassembled. The staff first controls the third motor 633 to work through the control center of the five-axis linkage turning and milling composite machining device, and makes the driving block 634 move along the first threaded rod 632 toward the side close to the tool holder 3. The first connecting rod 635 acts on the second connecting rod 636. Since the second connecting rod 636 and the third connecting rod 637 are parallel to each other, the upper end of the second connecting rod 636 is hinged to the bottom of the operating block 616, and the upper end of the third connecting rod 637 is hinged to the bottom of the rectangular frame 611, so that the rectangular frame 611 and the operating block 616 are both swung toward the side close to the tool holder 3. When the operating block 616 is close to the tool holder 3, the staff needs to control the first motor 21 to stop running temporarily and control the second motor 612 to run through the control center of the five-axis linkage turning and milling composite machining device. After the second motor 612 works, it drives the threaded shaft 613 to rotate. Since the threaded shaft 613 is threadedly connected with the movable plate 614, the rectangular sleeve 615 fixed on the movable plate 614 is sleeved on the outer side of the threaded shaft 613, and the sliding plate 617 is fixed to the end of the rectangular sleeve 615 and slidably cooperates with the limiting groove 6161 on the operating block 616, so that the sliding plate 617 moves along the limiting groove 6161 toward the side close to the tool holder 3, and the first cross bar 618 moves synchronously with the sliding plate 617. The second vertical T-shaped slider 6193 makes the bottom surface of the bottom block 6195 press against the inner bottom wall of the retraction groove 6183 under the elastic force of the second spring 6194, so that the push plate 619 moves synchronously with the second vertical T-shaped slider 6193. The side of the abutment block 6197 away from the second motor 612 abuts against the side of the mounting block 4 away from the tool holder 3, and then the third spring 6198 is compressed. At the same time, the mounting block 4 pushes the second cross bar 71 away from one end of the second motor 612. When the fourth abutment slope 711 abuts against the third abutment slope 6201, the rubber block 6184 is slightly deformed, and the second vertical T-shaped sliding block 6193 rises along the second vertical T-shaped sliding groove 6192 and compresses the second spring 6194. When the bottom block After the bottom surface of the bottom block 6195 is lifted to the height of the upper surface of the first cross bar 618, the bottom surface of the bottom block 6195 is pressed against the upper surface of the first cross bar 618 under the action of the second spring 6194. As the sliding plate 617 and the first cross bar 618 continue to move, the fixed block 621 moves synchronously, and the driving rod 622 moves from the straight groove 61621 close to the second motor 612 side through the oblique connecting groove 61622 to the straight groove 61621 away from the second motor 612 side. At this time,The first vertical T-shaped slider 6181 slides upward along the first vertical T-shaped slide groove 6171 and lifts the first cross bar 618, the sliding plate 617 and the first cross bar 618 continue to move forward, and the first abutting inclined surface 6182 abuts against the second abutting inclined surface 532, so that the connecting block 53 moves upward and compresses the first spring 52, and the connecting block 53 drives the movable plate 54 and the hook block 55 to move upward synchronously until the hook block 55 is completely retracted into the right-angled trapezoidal through hole 46, and the inner top wall of the connecting hole 531 of the connecting block 53 is tightly pressed against the inner bottom wall of the retraction groove 6183. The staff needs to control the control center of the five-axis linkage turning and milling composite machining device through the control center of the five-axis linkage turning and milling composite machining device. The second motor 612 is controlled to work in the reverse direction, so that the mounting block 4 moves with the first crossbar 618 toward the side away from the tool holder 3. After the driving rod 622 returns to the slot 61621 close to the second motor 612, the mounting block 4 is located in the limit slot 6161 (at this time, the first crossbar 618 is separated from the connecting block 53, and the mounting block 4 is in a free state). The staff needs to control the operation of the first motor 21 and the third motor 633 through the control center of the five-axis linkage turning and milling composite machining device. The first motor 21 continues to operate to continue to process the workpiece to be processed through the remaining turning tools 33 to ensure the processing efficiency of the workpiece. The third motor 633 runs and makes the pushing assembly 61 away from the tool holder 3, so that the staff can replace the turning tool 33 on the mounting block 4, ensuring the safety during the tool replacement process. Similarly, after the turning tool 33 is replaced, the staff can complete the operation of installing the mounting block 4 in the placement slot 31 by controlling the control center of the five-axis linkage turning and milling composite machining device, thereby completing the replacement of the turning tool 33.
