[0002] CNC machine tools are an important basic equipment in modern industry and a means of production for various pillar industries such as automobiles, aerospace, mold making, and electronics. The rotary table is one of the most widely used components.

[0003] Currently, most rotary tables on the market are single-axis rotary tables, some of which have a central built-in hydraulic circuit, but their motion modes are limited. In contrast, existing multi-axis linkage rotary tables have small table sizes, and it is difficult to design and implement a central built-in hydraulic circuit for multi-axis linkage rotary tables. They generally do not have a built-in central hydraulic circuit, which makes the installation of automated fixtures more complicated and the usage efficiency low. Summary of the Invention

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figure 1-4 As shown, the present invention is a multi-axis CNC rotary table with a central oil circuit, including a rotary table base 1, a B-axis rotary table 2 is provided on the top of the rotary table base 1, a C-axis rotary table 6 is provided on the top of the B-axis rotary table 2 via a C-axis base 4, the C-axis rotary table 6 is fastened to the top of the C-axis base 4 by a rotary table clamping block 7, the C-axis base 4 is fixed to the top of the B-axis rotary table 2 by fastening screws 8, and a central oil circuit module 3 is provided at the center of the interior of the B-axis rotary table 2 and the C-axis rotary table 6.

[0023] Furthermore, the central oil circuit module 3 includes a BC axis oil circuit plate inlet 301 fixed to the side wall of the turntable base 1 via a first fixed bracket 302 and a second fixed bracket 303. A BC axis oil circuit adapter plate 313 is fixedly connected to the top surface of the turntable base 1 near the BC axis oil circuit plate inlet 301 via a third fixed bracket 305. A first BC axis oil circuit plate outlet 304 is fixedly connected to the end of the BC axis oil circuit adapter plate 313 away from the BC axis oil circuit plate inlet 301. The first BC axis oil circuit plate outlet 304 is located away from the BC axis oil circuit adapter plate 301. One end of 13 is fixedly connected to the top surface of the B-axis center oil circuit mandrel 311. The top of the B-axis center oil circuit mandrel 311 is fixedly connected to the B-axis center oil circuit flange 310. The top surface of the B-axis center oil circuit flange 310 is fixedly connected to the outlet 312 of the second BC-axis oil circuit plate. The end of the outlet 312 of the second BC-axis oil circuit plate away from the B-axis center oil circuit flange 310 is connected to the C-axis center oil circuit mandrel 308 through the oil pipe 309. The end of the C-axis center oil circuit mandrel 308 is provided with a C-axis oil circuit port cover plate 306 and a C-axis center oil circuit flange 307.

[0024] It should be noted that the C-axis oil passage cover plate 306 is fixed to the end face of the C-axis central oil passage flange 307 by screws in the prior art, which is used to block the oil flowing out of the central oil passage hole set inside the C-axis central oil passage spindle 308. The C-axis oil passage cover plate 306 needs to be removed from the end face of the C-axis central oil passage flange 307 before the use of the central oil passage module 3.

[0025] It should be noted that several fastening holes are evenly spaced at the edge of the C-axis central oil passage flange 307. The user can fix the C-axis central oil passage flange 307 to the C-axis rotary table 6 by passing screws through the fastening holes in the prior art, and connect the C-axis central oil passage flange 307 to the oil passage interface in the external automated tooling fixture by passing screws through the fastening holes, thereby connecting it to the C-axis rotary table 6.

[0026] The C-axis rotary table 6 is fitted onto the C-axis center oil circuit spindle 308 at its internal center shaft, and the B-axis rotary table 2 is fitted onto the B-axis center oil circuit spindle 311 at its internal center shaft.

[0027] The C-axis center oil passage spindle 308 has a center oil passage hole inside, and the B-axis center oil passage spindle 311 also has a center oil passage hole inside.

[0028] The B-axis rotary table 2 includes a B-axis rotary table surface 201 disposed on its top, and the C-axis rotary table 6 includes a C-axis rotary table surface 601 disposed on its top.

[0029] An adjustment block 5 is provided at the connection between the C-axis base 4 and the side wall of the B-axis turntable 201 to adjust the position of the C-axis base 4.

[0030] This device features a simple structure, convenient installation, and high integration. It not only enables multi-axis linkage machining but also facilitates oil supply while installing automated tooling fixtures through the central oil circuit module 3, thus meeting the needs of automated production lines and solving the spatial interference problem caused by external piping. The central oil circuit module 3 has a sophisticated structure and is easier to manufacture. At the same time, the C-axis oil circuit port cover plate 306 can easily seal the oil outlet of the central oil circuit module 3 to prevent contamination.

[0031] Reference Figure 1 As shown, the B-axis rotary table 201 on the B-axis rotary table 2 and the C-axis rotary table 601 on the C-axis rotary table 6 in this device can rotate in the direction shown in the figure. Through the settings of the control system, motion system and servo motor in the prior art, arbitrary clockwise and counterclockwise rotation can be performed, thereby completing the multi-axis linkage machining function.

[0032] Working principle: When this device is working, the B-axis turntable 2 and the C-axis turntable 6 can rotate 360 ​​degrees in two dimensions through the existing control system, and can rotate independently to form a multi-axis turntable, thereby realizing multi-axis linkage machining.

[0033] During the rotation of B-axis rotary table 2 and C-axis rotary table 6, the central oil circuit module 3 enables the device to customize automated tooling fixtures according to customer needs and supply oil to them, thereby meeting the requirements of automated production lines. At the same time, the device only needs to be connected to the external oil inlet pipe through the BC axis oil circuit board inlet 301. It will not follow the rotation of B-axis rotary table 2 and C-axis rotary table 6 during their rotation, and its position is fixed, making it simple and efficient to use.

[0034] When installing the automated tooling fixture on this device, simply loosen the screws on the C-axis oil port cover plate 306, remove the C-axis oil port cover plate 306, and then fix the automated tooling fixture to the slot or mounting hole on the C-axis turntable surface 601. At this time, the oil supplied by the external oil inlet pipe will sequentially enter the automated tooling fixture through the BC-axis oil circuit board inlet 301, the BC-axis oil circuit adapter plate 313, the first BC-axis oil circuit board outlet 304, the B-axis center oil circuit mandrel 311, the B-axis center oil circuit flange 310, the second BC-axis oil circuit board outlet 312, the oil pipe 309, and the C-axis center oil circuit mandrel 308, thereby completing the oil supply.

[0035] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
