The gear shaft is supported by the angular contact bearing 35, the needle bearing 38 and the plane bearing 39 and is fastened by the second lock nut 34. The third cylinder 31 is fixed to the second connecting plate.

The action process of the lower rotating mechanism is as follows: the third cylinder 31 is ventilated to push the gear shaft to drive the cutter head 40 to rotate 180 degrees, so that the first group of cutters 41 and the second group of cutters 42 are exchanged. When the first group of cutters 41 and the second group of cutters 42 are exchanged, the number of cutters is increased by one time under the condition that the size of the cutter head 40 is not increased by the volume of the cutter storage. For example, the cutter head 40 is originally provided with 4 cutters, which can be increased from 4 to 8.

Further, the lower rotation mechanism may further include a third hydraulic damper 33, and the positional accuracy of the rotation of the cutter head 40 may be adjusted by the third hydraulic damper 33.

When the machine tool provided with the linear moving rotary tool magazine is used specifically, the control logic of the machine tool is as follows: firstly, a tool grabbing instruction is sent out, and then whether the position of the tool magazine is in the tool magazine or not is judged. If the judgment result is yes, the first rotating mechanism 10 is started, and the first gear shaft 12 drives the rotating arm 13 to rotate by a predetermined angle (for example, anticlockwise rotation by 90 °) along a predetermined direction, so as to form a processing avoiding space; if the judgment result is negative, further judging whether the cutter changing position is correct, if so, directly starting the linear moving mechanism 20, and pushing the cutter disc 40 to move and extend by the second air cylinder 21 to realize the function of grabbing the cutter; if the cutter head is not correct, the second rotating mechanism 30 is started to exchange the first group of cutters 41 and the second group of cutters 42, then the linear moving mechanism 20 is started again, and the second air cylinder 21 pushes the cutter head 40 to move and extend, so that the cutter head can be grabbed. When the knife grasping is finished, the cutter disc 40 is pushed by the second air cylinder 21 to move and retract. Then, the first gear mechanism is started to reset.
