Further, as shown in fig. 3-5, a mandrel 20 and a rotary joint 19 are arranged in the swing seat 6; the upper end of the mandrel 20 is connected with the lower end of the rotating shaft 3; the rotary joint 19 is fixedly arranged in the swing seat 6 and sleeved at the lower end of the mandrel 20, and the mandrel 20 can rotate in the rotary joint 19; one or more air passages 23 are formed in the rotary joint 19, the mandrel 20, the rotary shaft 3 and the clamping seat 13; the air passages 23 are sequentially communicated to form one or more control air passages, so that air can be sequentially conveyed to each air chuck 2 through the rotary joint 19, the mandrel 20, the rotary shaft 3 and the clamping seat 13; the number of the control air channels is equal to that of the air chucks 2.

Due to the structure, the control gas circuit is arranged in the swing seat 6, so that the structure of the whole swing seat 6 is more compact, and the influence of an external gas circuit 23 on the work of equipment is avoided; if the pneumatic chuck 2 is externally arranged and is connected with an air source through an externally arranged hose, the hose can be wound together when the rotating shaft 3 rotates, so that the equipment is blocked; if the pipeline is a hard pipeline, the rotating shaft 3 cannot rotate; by adopting the structure, the rotary joint 19 is fixed in position and does not act, the rotary joint 19 is connected with the gas source through the pipeline, and then the gas is sent to the pneumatic chuck 2 to control the pneumatic chuck 2 to act, so that various problems in an external gas circuit can be avoided.

As shown in fig. 6, 4 air chucks 2 are arranged at the top of the

clamping seat

13, 4 air paths 23 are respectively formed in the rotary joint 19, the mandrel 20, the rotating shaft 3 and the clamping seat 13, then the rotary joint 19, the mandrel 20, the rotating shaft 3 and the air paths 23 in the clamping seat 13 are connected into 4 control air paths, and each control air path independently supplies air for 1 air chuck 2 and controls the action of the air chuck 2.

Furthermore, one or more groups of annular grooves are formed in the inner side of the rotary joint 19 from bottom to top, and the number of the groups of the annular grooves is equal to the number of the control gas circuits; each group of annular grooves comprises a gas connecting groove 24 and sealing grooves 25 positioned on the upper side and the lower side of the gas connecting groove 24, and sealing rings are arranged in the sealing grooves 25; each air passage 23 on the rotary joint 19 and each air passage 23 on the spindle 20 communicate through a different air connecting groove 24.

Because the mandrel 20, the rotating shaft 3 and the clamping seat 13 are fixedly connected with each other to form a whole, the end parts of the internal air passages 23 are directly butted. The spindle 20 is rotatably connected with the rotary joint 19, when the spindle 20 rotates along with the rotary shaft 3, the ends of the internal air passages 23 of the rotary joint 19 and the spindle 20 cannot be always butted, so that the air passages 23 on the rotary joint 19 can be communicated with the air passages 23 on the spindle 20 by arranging the air connecting grooves 24 on the rotary joint 19. Due to the existence of the gas connecting groove 24, when the mandrel 20 rotates, the gas inlet end of the gas path 23 on the mandrel 20 can always rotate in the gas inlet groove, so that the gas outlet end of the gas path 23 on the rotary joint 19 can always be communicated with the gas path 23 on the mandrel 20 through the gas connecting groove 24; in order to prevent gas from leaking from the gas connecting groove 24, a seal groove 25 and a seal ring are provided on both upper and lower sides of the gas connecting groove 24.

As shown in fig. 6, there are 4 air chucks 2 in the figure, and 4 control air paths are needed, then 4 groups of annular grooves are arranged on the inner side of the

rotary joint

19, 12 annular grooves can be arranged, including 4

gas connecting grooves

24 and 8 sealing grooves 25, or as shown in fig. 6, 9 annular grooves are arranged, and the condition that two adjacent groups share a common sealing groove exists. Since the air passages 23 are opened in different directions, only 2 air passages 23 on the mandrel 20 can be seen in butt joint with 2 air passages 23 on the rotary joint 19 in the sectional view of fig. 5.

As shown in fig. 3-5, on the air path 23 on the rotary joint 19, the mandrel 20, the rotary shaft 3 and the clamping seat 13, the horizontal air path 23 is directly drilled from the side surface, then the side surface is blocked by a plug, and the vertical air path 23 is directly drilled from the upper end and the lower end.

The structure of a rotary shaft driving device and a swing shaft driving device of the existing swing rotary table is complex, and the rotary shaft driving device and the swing shaft driving device are driven by a servo motor and a worm and gear mechanism, so that the whole equipment is not compact in structure, difficult to assemble and easy to consume. The rotary shaft driving device and the swinging shaft driving device both adopt torque motors, and the torque motors have the characteristics of high load, high acceleration, high dynamic and the like, can well meet the requirements of efficient and high-precision machining of the swinging rotary table, and simplify the structure of equipment.

The rotor 21 of the revolving shaft motor is connected with the revolving shaft 3 through the revolving shaft motor connecting sleeve 16, which facilitates the connection of the motor and the shaft; in the prior art, the end part of the rotor 21 of the rotating shaft motor is generally connected with other parts in a bolt connection mode, but in the utility model, the end part of the rotor 21 of the rotating shaft motor is inconvenient to be directly connected with the lower end of the rotating shaft 3 in a bolt connection mode and is inconvenient to open a threaded hole on the rotating shaft, if the threaded hole is opened, the threaded hole can penetrate through the upper end and the lower end of the whole rotating shaft, and the threaded hole is longer; when the rotor 21 of the rotating shaft motor is connected to the rotating shaft 3 through the connecting sleeve 16 of the rotating shaft motor, it is only necessary to make a threaded hole in the connecting sleeve 16 of the rotating shaft motor and to connect the end of the rotor 21 of the rotating shaft motor through a bolt, as shown in fig. 4.

Further, the bottom of the swing seat 6 is through, a stator mounting plate 17 is covered at the bottom of the swing seat 6, and the stator mounting plate 17 is used for limiting the downward movement of the revolving shaft motor stator 22; the middle part of the stator mounting plate 17 is sunken towards the interior of the swing seat 6 to form a rotary joint mounting cavity, and the rotary joint mounting cavity is positioned in the rotary shaft motor; the rotary joint 19 is arranged in the rotary joint mounting cavity, the bottom of the rotary joint 19 is fixedly connected with the stator mounting plate 17, and the mandrel 20 penetrates through the top of the rotary joint mounting cavity and is connected with the bottom of the rotary shaft 3.

Due to the structure, the bottom of the swing seat 6 is communicated, so that the rotating shaft motor is convenient to install and overhaul. Meanwhile, the stator mounting plate 17 is concave, so that a mounting space is reserved for the rotary joint 19; and simultaneously, the rotary shaft motor is separated from the mandrel 20 and the rotary joint 19, so that the hose is prevented from interfering the operation of the rotary shaft motor when the rotary joint 19 is connected with a hose and connected with an air source.

Furthermore, a rotor brake caliper 14 is arranged in the swing seat 6, and the rotor brake caliper 14 is used for clamping or loosening the rotor 3. In the present invention, the rotary shaft brake caliper 14 is a pneumatic caliper.

Further, as shown in fig. 2, the swing shaft 4 and the swing shaft motor are arranged in the support 1; the swing shaft 4 is rotatably arranged on the support 1 through a swing shaft bearing 9; the swing shaft motor is an internal torque motor, one end of the swing shaft 4 extends into the swing shaft motor, and a swing shaft motor connecting sleeve 10 is fixedly sleeved on the swing shaft 4; the swing shaft motor rotor 11 is sleeved on the swing shaft motor connecting sleeve 10, and the swing shaft motor stator 7 is fixedly arranged in the support 1.

Because the swing shaft motor is an internal torque motor, the structure in the whole support 1 can be more compact. The swing shaft motor rotor is connected with the swing shaft through the swing shaft motor connecting sleeve, so that the connection between the motor and the shaft is facilitated.

Further, a swing shaft brake caliper 8 is arranged in the support 1, and the swing shaft brake caliper 8 is located at a swing shaft motor connecting sleeve 10 and used for tightly holding or loosening the swing shaft motor connecting sleeve 10. In the present invention, the swing shaft brake caliper 8 is a pneumatic caliper.

Furthermore, the rotating shaft 3 and the swinging shaft 4 are hollow structures, so that the mass of parts can be reduced, the material can be saved, and the wiring is convenient; for example, a wiring channel can be formed in the swing seat 6, a power line and an air supply hose can enter the swing shaft 4 from the support 1, then enter the wiring channel in the swing seat, finally penetrate to the bottom of the swing seat 6 and then are connected with a rotary joint or a rotary shaft motor; the cooling pipeline for cooling the rotating shaft motor can also enter the swinging shaft 4 from the support 1, then enter the wiring channel inside the swinging seat, finally penetrate to the bottom of the swinging seat 6 and then cool the rotating shaft motor. An end cover 18 can be arranged at the bottom of the swing seat 6 and used for covering the power line, the air supply hose and the cooling pipeline.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the utility model can be made, and equivalents and modifications of some features of the utility model can be made without departing from the spirit and scope of the utility model.
