[0002] With the rise of science and technology, there are more and more five-axis CNC machine tools. The five-axis has the RTCP function, which can automatically convert according to the spindle's swing length and the mechanical coordinates of the rotary table. When compiling a program, you only need to consider the coordinates of the workpiece, not the spindle's swing length and the position of the rotary table. Five-axis CNC machine tools generally use a five-axis swing head. The five-axis swing head is an advanced CNC machine tool technology that allows simultaneous processing operations in multiple directions. Compared with traditional three-axis (X, Y, Z-axis) machine tools, five-axis swing head machine tools have higher flexibility and processing capabilities. Five-axis swing head machine tools are usually used for complex processing tasks, such as aerospace parts, automotive parts, molds and other fields.

[0003] For example, a five-axis swing head with authorization announcement number CN210209585U and publication date March 31, 2020, includes a swing head bracket, a bracket cover, a swing head C-axis assembly and an electric spindle assembly, the swing head bracket is a carbon fiber bracket, the swing head C-axis assembly is installed on the top of the swing head bracket, the bracket cover is installed on one side of the swing head bracket, and the electric spindle assembly is installed on the other side of the swing head bracket; longitudinal reinforcement ribs and transverse reinforcement ribs are also arranged in the swing head bracket, and the longitudinal reinforcement ribs and the transverse reinforcement ribs are hollow structures; the five-axis swing head provided by the utility model, the swing head bracket is a carbon fiber bracket, which can effectively improve the overall heat dissipation performance of the swing head; compared with the metal shell, the carbon fiber shell has a smaller thermal deformation when heated, and at the same time reduces the overall mass of the five-axis swing head, making the movement lighter and easier to load and unload during five-axis processing; the reinforcement ribs adopt a hollow structure, which can effectively absorb vibrations during processing, and it has light weight and strong structure.

[0004] For example, a five-axis swing head with a cooling system and a cooling method with an authorization announcement number of CN116979760B and an authorization announcement date of July 9, 2024, relates to the technical field of five-axis swing heads, a C-axis, an A-axis, an electric spindle and a swing head housing, the A-axis includes a direct-drive motor and a flange, the direct-drive motor is installed on the swing head housing through the flange, sealing rings are respectively provided on both end surfaces of the stator core of the direct-drive motor, a through hole is provided in the stator core, hollow tubes that are interconnected are provided in the through holes, coolant is provided in the hollow tubes, a heat dissipation cavity is arranged around the motor housing of the direct-drive motor, an air inlet is provided at one end of the motor housing, and an air outlet is provided at the other end of the motor housing, a sound-absorbing layer is provided on the inner wall surface of the swing head housing, an air inlet pipeline and an air outlet pipeline are provided in the swing head housing, the air outlet of the air inlet pipeline is connected to the air inlet of the heat dissipation cavity, the present invention adopts multiple methods to cool the five-axis swing head to avoid dust and impurities being sucked into the swing head housing.

[0005] In order to ensure the processing direction, multiple driving elements will be set on the five-axis swing head, which will make the swing head larger in size and weight. It will be more difficult to install the swing head, increase the burden on the machine tool spindle, and increase the manufacturing cost of the swing head.

A cavity 35 is arranged inside the connector 1, and hydraulic oil is arranged inside the cavity 35 and the sliding groove 38. 42, a mounting groove 36 is provided on the outer wall of one side of the connector 1, and a threaded rod 37 is installed inside the mounting groove 36 through a bearing, one end of the threaded rod 37 extends into the cavity 35, and a piston block 41 is connected to the outer thread of the threaded rod 37, and one end of the machine tool spindle is connected to the connector 1 so that the protrusion on the spindle is stuck in the mounting groove 34. Subsequent workers can use a wrench to rotate the threaded rod 37 so that the hydraulic oil 42 in the cavity 35 enters the three sliding grooves 38, and then the insertion rod 39 will be lifted up, so that the insertion rod 39 extends out of the mounting groove 34, so that one end of the insertion rod 39 is inserted into the spindle, so that the connector 1 and the machine tool spindle are installed together, and the piston block 41 is slidably connected to the cavity 35.

[0033] Working principle: When using the swing head, the device can be connected to the breakdown spindle first. This process connects one end of the machine tool spindle to the connector 1, so that the protrusion on the spindle is stuck in the placement groove 34. Later, the worker can use a wrench to turn the threaded rod 37, so that the hydraulic oil 42 in the cavity 35 enters the three sliding grooves 38, and then the plug rod 39 will be lifted up, so that the plug rod 39 extends out of the placement groove 34, so that one end of the plug rod 39 is inserted into the spindle, so that the connector 1 and the machine tool spindle are installed together. When the swing head needs to be adjusted later, the controller 11 will receive an external command to reverse the drive motor 21 and start it, and the screw rod 22 will carry the piston plate 2 0 slides inside the liquid storage tank 19, so that the piston plate 20 retracts to one side of the liquid storage tank 19. During this process, the liquid inside the rubber bag 17 will no longer be stressed, and then under the elastic rebound effect of the support spring 32, the connecting cylinder 30 will slide inside the sliding cylinder 43, so that the block 31 inside the sliding cylinder 43 is stuck in the groove 29 on the fixed cylinder 28, so that the fixed cylinder 28 and the connecting end 33 are connected together. After that, when the angle of the installation box 6 is adjusted, the driving motor 10 can be operated to start, so that the active pulley 12 rotates with the driven pulley 14 through the synchronous belt 15, and the driven pulley 14 rotates with the transmission shaft 13, and the transmission shaft 13 will drive the fixed cylinder 28 and the connecting cylinder 3 0 transmission, since the fixed cylinder 28 and the installation box 6 are integrated, the fixed cylinder 28 will rotate with the installation box 6, so that the installation box 6 rotates around the shell 3 to achieve the adjustment of the swing head. After the adjustment of the swing head is completed, under the control of the controller 11, the drive motor 21 will start forward rotation, and the screw rod 22 will slide the piston plate 20 inside the liquid storage tank 19, so that the liquid inside the liquid storage tank 19 flows into the rubber bag 25 through the pipeline, and then the rubber bag 25 will swell, so that the rubber bag 25 swells and fills the embedded groove 26 on the fixed end 24, so that the fixed cylinder 28 is fixed, and the self-locking of the swing head is achieved. In this process, the liquid inside the liquid storage tank 19 will pass through another A pipe flows into the interior of the rubber bag 27, causing the rubber bag 27 to bulge, pushing the connecting tube 30 to slide inside the slide tube 43, so that the two blocks 31 thereof disengage from the slots 29 on the fixed tube 28, so that the connecting tube 30 and the fixed tube 28 are no longer linked together. When the swing head is used to process the workpiece later, the drive motor 10 can be started to make the active pulley 12 rotate with the driven pulley 14 through the synchronous belt 15, and then the transmission shaft 13 will rotate, so that the transmission shaft 13 rotates with the active gear 17, and then through the transmission with the driven gear 16, the connecting shaft 9 will rotate with the rotating end 7, so that the rotating end 7 rotates with the tool to realize the processing of the workpiece.
