Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0026] Figure 1 Shows a schematic diagram of a five-axis linkage turret lathe in the present utility model, Figure 2 Shows a cross-sectional view of the swing head part in the present utility model, Figure 3 Shows a structural schematic diagram of the connecting part in the present utility model, Figure 4 Shows a cross-sectional view of the connecting part in the present utility model. The turret lathe includes: a turret lathe body 1, a moving guide rail 2 provided on the turret lathe body 1, and a swing head mechanism 3 provided on the moving guide rail 2. The moving guide rail 2 provides stable support and guiding functions for the swing head mechanism 3, and the swing head mechanism 3 is used to change the working direction so that the turret lathe can adapt to different working environments.

[0027] The swing head mechanism 3 includes: a lead screw 31, a first driving motor 32, a swing head part 33 and a connecting part 34. The swing head part 33 is connected to the lead screw 31 based on the connecting part 34. The output end of the first driving motor 32 is connected to the lead screw 31, and the other end of the lead screw 31 is inserted into the turret body. The first driving motor 32 is used to drive the lead screw 31 to rotate, thereby driving the swing head part 33 to move up and down on the moving track. The swing head part 33 is used to rotate the working angle, so that the milling cutter rotates to the corresponding angle.

[0028] Furthermore, a connecting block is provided on the swing head mechanism 3, and a threaded connecting hole is provided on the connecting block. The connecting block is inserted on the lead screw 31. When the lead screw 31 rotates, the connecting block will move on the lead screw 31, thereby driving the entire swing head mechanism 3 to move on the moving guide rail 2.

[0029] The connecting part 34 includes: a linkage rod 341 and a driven gear 342. One end of the linkage rod 341 is rotatably connected to the swing head mechanism 3. A keyway 3411 is provided on the linkage rod 341, and a stop block 3412 is arranged in the keyway 3411. The driven gear 342 is provided with an electromagnet block, and the stop block 3412 is driven by the electromagnet block to move between the inside and the outside of the keyway 3411. When the gear position is outside the keyway 3411, the linkage rod 341 and the driven gear 342 are connected, and the rotation of the driven gear 342 drives the linkage rod 341 to rotate; when the gear position is inside the keyway 3411, the outer surface of the linkage rod 341 contacts the driven gear 342, and the rotation of the driven gear 342 has no influence on the linkage rod 341.

[0030] Further, a spring 3413 is arranged at the bottom of the stop block 3412. One end of the spring 3413 is connected to the bottom of the stop block 3412, and the other end of the spring 3413 is connected to the keyway 3411. The spring 3413 is used to reset the stop block 3412 located outside the keyway 3411 to the inside of the keyway 3411. When the electromagnet block is energized, the stop block 3412 is attracted so that the upper end surface of the stop block 3412 abuts against the lower end surface of the electromagnet block. At this time, the spring 3413 is stretched, and the spring 3413 has a pulling force on the stop block 3412. After the electromagnet block is powered off, there is no suction force on the stop block 3412. After the stop block 3412 is subjected to the pulling force of the spring 3413, it will reset to the inside of the keyway 3411.

[0031] Further, a combined groove is arranged in the middle area of the driven gear 342, and the linkage rod 341 is inserted into the combined groove. The combined groove is composed of a circular groove and a rectangular groove. The rectangular groove is located above the circular groove. The linkage rod 341 is inserted into the circular groove, and the electromagnet block is arranged on the side wall of the rectangular groove far from the circular groove. When the electromagnet block is energized, the electromagnet block has magnetism, and the electromagnet block has an attractive force on the stop block 3412. When the driven gear 342 rotates and the electromagnet block rotates above the stop block 3412, after the stop block 3412 is subjected to the attractive force, the stop block 3412 moves into the rectangular groove, and the stop block 3412 abuts against the inner wall of the rectangular groove, thereby driving the linkage rod 341 to rotate. The rotation of the linkage rod 341 drives the swing head mechanism 3 to rotate to a suitable angle, realizing the situation that one driving mechanism achieves two-axis rotation.

[0032] Further, the driven gear 342 meshes with the lead screw 31. The driven gear 342 is driven by the lead screw 31 to rotate around its geometric center. When the lead screw 31 is driven by the output end of the first driving motor 32 to rotate, it will drive the driven gear 342 to rotate. The rotation of the driven gear 342 drives the linkage rod 341 to rotate, and the rotation of the linkage rod 341 drives the swing head mechanism 3 to rotate. That is, when the lead screw 31 rotates forward, the output end of the swing head mechanism 3 turns from pointing to the left side of the turret body to pointing to the bottom of the turret body. When the lead screw 31 rotates reversely, the output end of the swing head mechanism 3 turns from pointing to the bottom of the turret body to pointing to the left side of the turret body. This realizes the situation where one driving mechanism achieves two-axis rotation, reducing the weight of one driving mechanism on the turret body.

[0033] Specifically, when the electromagnet is energized, the electromagnet has an attractive force on the stopper 3412, causing the stopper 3412 to move from inside the keyway 3411 to abut against the electromagnet. The upper end surface of the stopper 3412 abuts against the lower end surface of the electromagnet, and the lower half of the stopper 3412 abuts against the inner wall of the keyway 3411. That is, when the driven gear 342 rotates, the electromagnet drives the stopper 3412 to rotate, the stopper 3412 drives the linkage rod 341 to rotate, and the linkage rod 341 drives the swing head portion 33 to rotate, so that the swing head portion 33 rotates to the corresponding position. Then the electromagnet is de-energized, and the spring 3413 has a pulling force on the stopper 3412, causing the stopper 3412 to reset into the keyway 3411. At this time, the outer surface of the linkage rod 341 contacts the driven gear 342, and the rotation of the driven gear 342 has no influence on the linkage rod 341.

[0034] Further, the swing head mechanism 3 is provided with a connecting plate 35, and one or more sliders 351 are arranged on the connecting plate 35. The swing head mechanism 3 is slidably connected to the moving guide rail 2 based on the sliders 351. In this embodiment, four sliders 351 are arranged on the connecting plate 35, and one of the four sliders 351 is correspondingly arranged at one of the four top corners of the connecting plate 35. Connecting at the four corners can ensure that the stress is evenly distributed throughout the structure, rather than concentrated at a certain point or a certain part, which helps to prevent the swing head mechanism 3 from falling off the moving guide rail 2. A rectangular hole is arranged at the center position of the connecting plate, and the rectangular hole is used to clamp the connecting block, so that the connecting block can be connected to the lead screw, thereby driving the entire swing head mechanism to move.

[0035] Furthermore, the swing head 33 includes: a processing part and a tool, and the tool is installed in the processing part. A locking device is provided in the processing part, and when the tool is inserted into the processing part, the locking device locks the tool to prevent the tool from being offset during use, thereby improving the processing accuracy of the processing part.

[0036] Furthermore, a driving cylinder is provided on the swing head part 33, and the processing part is driven by the driving cylinder to move up and down in the vertical direction, so that the processing part can move a longer distance in the vertical direction and have a larger processing range, thereby avoiding the situation where the swing head mechanism 3 is located at the bottom of the movable guide rail 2 and still cannot be processed, thereby increasing the processing range of the processing part, and allowing some processing tasks that originally required multiple processes to be completed to be completed on a single machine tool at one time, thereby reducing the transportation and waiting time in the production process and improving production efficiency.

[0037] Furthermore, a cutter head 11 is provided on the turret machine body 1, and more than one cutter is provided on the cutter head 11. In the present embodiment, the turret machine body includes twelve cutters, but the number of cutters can be increased or decreased according to actual conditions, such as eighteen cutters or even more cutters can be added to the turret machine body, so as to ensure that the turret machine can store a variety of different types of cutters, meet the cutting requirements of different shapes, and improve the flexibility of the CNC machine tool.

[0038] Furthermore, a second drive motor is provided on one side of the cutter disc 11, and the cutter disc 11 is driven to rotate by the second drive motor. The second drive motor is used to rotate the cutter disc 11 to a corresponding angle, rotate the unneeded cutter to other positions, and rotate the designated cutter to the working position. Secondly, the second drive motor drives the cutter disc 11 to rotate to different processing positions so that the cutter is subjected to more uniform force during the processing, effectively optimizes the cutting conditions, reduces the wear and damage of the cutter, and prolongs the service life of the cutter.

[0039] The utility model also proposes a CNC machine tool, which includes the above-mentioned five-axis linkage turret machine and a control module, wherein the five-axis linkage turret machine is located inside the CNC machine tool, and the control module is connected to the five-axis linkage turret machine by signal. The control module sends a corresponding signal to the turret machine, and the first drive motor drives the swing head mechanism to move to a corresponding position on the moving guide rail and drives the swing head mechanism to rotate to a corresponding working position.

[0040] In summary, in the present utility model, by providing a connecting portion, when the driven gear rotates and the electromagnetic block rotates above the stopper, after the stopper is attracted, the stopper moves into the rectangular groove and abuts against the inner wall of the rectangular groove, thereby driving the linkage rod to rotate. The rotation of the linkage rod drives the swing head mechanism to rotate to a suitable angle, achieving the situation where a driving mechanism achieves two-axis rotation.

[0041] In addition, the above has introduced in detail a five-axis linkage tool turret machine and a numerical control machine tool provided by the embodiments of the present utility model. Specific examples are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope.
