[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0042] At present, the swing head rotating seat adopts a servo numerical control turntable, and a large aperture through mode is adopted in the center, so that the matched electric spindle is directly installed on the disc surface or flange of the swing head rotating seat. The cooling pipeline, wire, cutting fluid and the like of the electric spindle are directly connected to the outside of the machine tool through the center or above the swing head rotating seat, and the electric spindle swings together when the swing head rotating seat rotates, which leads to a large space occupancy rate of the machine tool. The appearance of the machine tool is not clean and tidy. In addition, at present, the swing head rotating seat adopts a servo numerical control turntable, and the conventional numerical control turntable is driven by a worm gear, and the positioning accuracy is also guaranteed by the worm gear. After long time use, the positioning accuracy may be poor, and the reverse gap may be too large. The defective rate of the parts produced by the machine tool is increased, the finish of the parts is poor, and even other parts of the machine tool are damaged.

[0043] The embodiment of the present application aims to solve one of the above technical problems, and therefore provides a swing head rotating seat and a five-axis machine tool. By applying the swing head rotating seat to the five-axis machine tool and connecting the electric spindle, at least the machining accuracy can be improved, and the product yield can be improved.

[0044] Specifically, as shown in Figures 1 to 5 The embodiment of the present application provides a swing head rotating seat, which is applied to a five-axis machine tool to install an electric spindle, and includes: a rotating seat body 1, which is installed on the five-axis machine tool, and is provided with an in-shaft end, an out-shaft end, and a shaft hole penetrating the in-shaft end and the out-shaft end; an oil distribution shaft 2, which is arranged in the shaft hole and connected with the electric spindle; a transmission mechanism 3, which is arranged on the rotating seat body 1 and transmissionally connected with the oil distribution shaft 2 and the electric spindle, and used for transmission of the oil distribution shaft 2 and the electric spindle; a positioning member 4, which is arranged at one end of the oil distribution shaft 2 at the out-shaft end, and used for measuring the rotation accuracy of the oil distribution shaft 2; and a driving mechanism 5, which is arranged on the rotating seat body 1, and used for driving the oil distribution shaft 2, the transmission mechanism 3 and the electric spindle to move.

[0045] In one specific example of the embodiment, a design of a swing head rotating seat is proposed, which is particularly suitable for the occasion of installing an electric spindle on a five-axis machine tool. The swing head rotating seat includes multiple key components that work together to ensure efficient and accurate operation of the device. First, the rotating seat body 1 is the core part of the device, which is designed to be installed in the appropriate position of the five-axis machine tool. The rotating seat body 1 has two main ports, namely the in-shaft end and the out-shaft end, which are connected by a shaft hole. The shaft hole allows the passage and rotation of shaft components.

[0046] Next, the oil distribution shaft 2 is ingeniously arranged inside the shaft hole, and its main function is to connect with the motorized spindle. The existence of the oil distribution shaft 2 is crucial to ensure that the motorized spindle can rotate smoothly and transmit power. In order to achieve effective transmission between the oil distribution shaft 2 and the motorized spindle, a transmission mechanism 3 is also designed in this embodiment, which is arranged on the rotating seat body 1 and forms a transmission connection between the oil distribution shaft 2 and the motorized spindle. The setting of the transmission mechanism 3 makes the power transmission between the oil distribution shaft 2 and the motorized spindle more efficient and stable.

[0047] In addition, in order to ensure the accuracy of the oil distribution shaft 2 during rotation, the embodiment also specially designs a positioning member 4. The positioning member 4 is arranged at one end of the oil distribution shaft 2 at the out shaft end, and its main role is to measure and ensure the rotation accuracy of the oil distribution shaft 2, which is crucial to the performance of the entire swing head rotating seat. Finally, in order to drive the movement of the entire system, including the oil distribution shaft 2, the transmission mechanism 3 and other related parts, the embodiment also provides a driving mechanism 5. The driving mechanism 5 is arranged on the rotating seat body 1, which is responsible for providing the necessary power to make the entire swing head rotating seat work in a predetermined manner and speed.

[0048] It needs to be elaborated that in the embodiment of the present application, the grating ruler is particularly selected as the positioning member 4, and this selection is based on the excellent performance of the grating ruler in accuracy and reliability.

[0049] As a precision measurement tool, the grating ruler detects the displacement and position of an object through optical principles and is widely used in various high-precision positioning systems. In this application, the use of the grating ruler can ensure the accuracy of positioning, thereby improving the performance and efficiency of the entire system. In addition, the durability and anti-interference ability of the grating ruler are also important factors for selecting it as the positioning member 4.

[0050] In one possible implementation, as shown in Figure 1 As shown in Figure 3 The rotating seat body 1 is provided with an oil-water-gas inlet end 6 arranged at the out shaft end of the rotating seat body 1 for input of oil-water-gas of the motorized spindle, and an oil-water-gas outlet end 7 arranged at the in shaft end of the rotating seat body 1 for output of oil-water-gas of the motorized spindle.

[0051] In one specific example of the embodiment, the rotating seat body 1 is provided with an oil-water-gas inlet end 6 which is carefully designed and arranged at the out shaft end of the rotating seat body 1, and its main function and role is for the input of oil-water-gas of the motorized spindle. In addition, there is also an oil-water-gas outlet end 7 which is also carefully designed and arranged at the in shaft end of the rotating seat body 1, and its main function and role is for the output of oil-water-gas of the motorized spindle.

[0052] It should be noted that the oil separation shaft 2 provided by the embodiments of the present application has an oil separation function, and the output functions of oil, water and gas are operated and output through the mounting surface of the electric spindle. The machine tool buttons corresponding to each function are tool loosening, tool clamping, cooling liquid inlet, cooling liquid outlet, tool striking and air blowing, cutting blowing, air curtain, cutting fluid, middle spraying and preparation. Through the above function keys, the oil, water and gas can be output from the inner oil separation shaft 2.

[0053] In a possible implementation manner, as shown in Figure 1 The rotating seat body 1 is provided with a locking hole member 8 arranged on the rotating seat body 1 and used for locking the oil-water-gas inlet end 6 and the oil-water-gas outlet end 7.

[0054] In a specific example of the present embodiment, the rotating seat body 1 is provided with a locking hole member 8 arranged on the rotating seat body 1 and used for locking the oil-water-gas inlet end 6 and the oil-water-gas outlet end 7. Such a locking hole member 8 is usually designed to be able to cooperate with a corresponding locking device to ensure that the oil-water-gas inlet end 6 and the oil-water-gas outlet end 7 can be firmly locked during the use of the rotating seat body 1, preventing loosening or falling off due to vibration or external force. In addition, the structural design of the locking hole member 8 should also consider facilitating the quick locking and unlocking operations of the operator to improve work efficiency and safety.

[0055] The material selection of the locking hole member 8 is also crucial, which needs to have sufficient strength and corrosion resistance to cope with various harsh working environments. Usually, such a component is made of stainless steel or special alloy materials to ensure its stability and reliability in long-term use. In addition, the design of the locking hole member 8 should also consider the compatibility with the rotating seat body 1 to ensure that the connection between the two is both firm and easy to maintain.

[0056] In a possible implementation manner, as shown in Figure 2 The rotating seat body 1 is provided with a locking member 9 arranged on the rotating seat body 1 and used for controlling the rotating seat body 1 to lock / unlock the electric spindle; and a locking drive oil cylinder connected with the locking member 9 and used for driving the locking member 9 to lock / unlock.

[0057] In a specific example of the present embodiment, in order to further improve the convenience and safety of operation, the rotating seat body 1 can also include a safety locking mechanism. This mechanism can prevent accidental starting of the electric spindle when the locking member 9 is in the unlocked state, thereby avoiding possible dangers. In addition, in order to adapt to different working environments and requirements, the design of the rotating seat body 1 allows users to replace different specifications of the locking member 9 and the oil cylinder as needed to achieve the best performance matching.

[0058] In a possible implementation manner, as shown in Figure 2As shown, the rotating seat body 1 is provided with a locking signal transmission component 11 arranged on the rotating seat body 1 and close to the locking drive oil cylinder, for transmitting the locking / unlocking signal of the rotating seat body 1.

[0059] In one specific example of the embodiment, the rotating seat body 1 is configured with a specific structure in which the locking signal transmission component 11 is arranged. This component is carefully designed and arranged at a specific position of the rotating seat body 1 and close to the locking drive oil cylinder, and its main function is to transmit the locking state signal and the unlocking state signal of the rotating seat body 1. In this way, it can ensure that the rotating seat body 1 can timely and accurately transmit the corresponding control signal when it needs to be locked or unlocked, thereby realizing accurate control of the rotating seat body 1.

[0060] The locking signal transmission component 11 generally includes a series of electronic components and connection lines, which are designed to withstand various physical and environmental pressures that the rotating seat body 1 may encounter during operation. In order to ensure the reliability of signal transmission, these components are often made of high-stability materials and advanced manufacturing processes. In addition, in order to adapt to different working environments, the locking signal transmission component 11 may also be equipped with special functions such as waterproof, dustproof and high-temperature resistance to ensure normal work under extreme conditions.

[0061] In one possible implementation, as shown in Figure 2 The rotating seat body 1 is further provided with an origin signal transmission component 12 arranged on the rotating seat body 1 for sending origin reference information to the driving mechanism 5; wherein the driving mechanism 5 is an incremental servo motor.

[0062] In one specific example of the embodiment, the swing head rotating seat further includes an origin signal transmission component 12, which is designed and arranged at a specific position of the rotating seat body 1, and its main function is to send accurate origin reference information to the driving mechanism 5; in this implementation, the driving mechanism 5 is embodied as an incremental servo motor, which is widely used in occasions requiring accurate position control due to its high precision and good control performance.

[0063] The incremental servo motor can ensure that the rotating seat body 1 can be accurately positioned to the initial position when starting or resetting by receiving the origin reference information from the origin signal transmission component 12. This positioning mechanism is crucial to ensure the stability and repeatability of the entire system. In addition, the design of the origin signal transmission component 12 also considers the anti-interference ability to ensure reliable work in various complex environments. In order to further improve the response speed and positioning accuracy of the system, a high-speed communication interface is adopted between the origin signal transmission component 12 and the incremental servo motor, so that the signal transmission is more rapid and accurate.

[0064] In a possible implementation form, as shown in Figure 4 backlash adjustment member 13 is provided on the rotating seat body 1 to reset the transmission mechanism 3; wherein the transmission mechanism 3 is a complex pitch worm gear.

[0065] In a specific example of the embodiment, the swing head rotating seat further comprises a backlash adjustment member 13, which is designed and arranged at a specific position of the rotating seat body 1, and its main function is to enable the transmission mechanism 3 to reset smoothly; further, the transmission mechanism 3 is designed as a worm gear with complex pitch characteristics, which not only improves the transmission efficiency, but also enhances the stability and accuracy of the entire mechanical system.

[0066] In addition, the arrangement of the backlash adjustment member 13 also considers the convenience of operation and the accuracy of adjustment. It usually includes a precise adjusting screw, by rotating the screw, the clearance between the worm gear and the worm can be finely adjusted to ensure the smoothness during transmission. This design enables the device to maintain high transmission accuracy after a long time of operation.

[0067] In a possible implementation form, as shown in Figure 4 shaft radial needle bearing 14 is arranged in the shaft hole of the rotating seat body 1 and is sleeved on the oil distribution shaft 2 to increase the shaft radial stiffness inside the rotating seat body 1.

[0068] In a specific example of the embodiment, the swing head rotating seat further comprises a shaft radial needle bearing 14, which is designed and arranged in the shaft hole of the rotating seat body 1 and is sleeved on the oil distribution shaft 2, and its main function is to increase the shaft radial stiffness inside the rotating seat body 1. This design not only improves the stability of the overall structure, but also ensures that the rotating seat body 1 can maintain good performance and longer service life in a high-load working environment. In this way, the shaft radial needle bearing 14 plays a crucial role in the mechanical system, which effectively disperses the axial and radial loads through its unique structure and material properties, thereby greatly improving the durability and reliability of the rotating seat body 1.

[0069] In addition, the use of the shaft radial needle bearing 14 can also reduce the vibration and noise generated by the rotating seat body 1 when rotating at high speed. Due to its compact design, the bearing can adapt to narrow spaces while providing sufficient support force to ensure the smooth operation of rotating parts. In design, the size and material selection of the bearing are calculated to meet the performance requirements of specific applications. For example, the outer ring and inner ring of the bearing are usually made of high-hardness steel to withstand heavy loads and prolong the service life. The rollers themselves may be made of special heat-treated alloy steel to improve their wear resistance and load capacity.

[0070] In one possible implementation, as shown in Figure 4 braking member 15 is provided on the rotating seat body 1 for controlling the rotating seat body 1 to stop swinging rotation.

[0071] In one specific example of the embodiment, the swing head rotating seat further comprises a braking member 15 designed and arranged at a specific position of the rotating seat body 1, which mainly functions to accurately control the swinging rotation of the rotating seat body 1 and ensure that it can be timely and accurately stopped, thereby improving the stability and safety of the entire system.

[0072] In addition, the braking member 15 also has the ability of self-adjustment, which can automatically adjust the braking force according to the motion state of the rotating seat body 1 to adapt to different working environments and conditions. This self-adjustment mechanism ensures that the braking member 15 can provide appropriate braking force in various situations, thereby effectively preventing the problems of excessive wear or insufficient braking force.

[0073] It should be noted that the braking member 15 provided in the embodiment of the application is a disc brake structure, and the brake disc in the brake structure is installed on the oil distribution shaft 2. When the hydraulic pressure pushes the piston, the piston forces the brake disc to deform and contact the inside of the rotating seat body 1 to generate friction force, achieving the function of braking the swing head rotating seat.

[0074] In one additional example of the application, forward and reverse limit switches are provided at the tail end of the swing head rotating seat. When the swing head rotating seat is rotating, the position limiting signal transmission is performed through the forward and reverse limit switches, effectively compensating for the insufficient soft limit of the encoder of the servo motor as the driving mechanism 5.

[0075] The embodiment of the application also provides a five-axis machine tool, as shown in Figure 5 which comprises an electric spindle 200 and the swing head rotating seat 100 described above, and the swing head rotating seat 100 is used to install the electric spindle 200.

[0076] The swing head rotating seat provided in the embodiment of the application has the following advantages:

[0077] 1. The structure of the built-in oil distribution shaft makes the oil, water and gas path of the electric spindle pass through the inside of the swing head rotating seat, which is more convenient to install and saves machine tool installation space.

[0078] 2. The positioning member is directly installed on the oil distribution shaft, which makes the position feedback of the rotation angle more accurate.

[0079] 3. The hard limit of the forward and reverse stroke limit switches at the end of the shaft is used together with the soft limit, which plays a dual protection role.

[0080] In addition, the embodiment of the present application further provides a five-axis machine tool on the basis of the above-mentioned swing head rotary seat. Since the five-axis machine tool adopts the above-mentioned swing head rotary seat, it not only inherits all the technical advantages of the swing head rotary seat, but also realizes additional improvements on this basis. Compared with the five-axis machine tool before the improvement, the five-axis machine tool provided by the embodiment of the present application has been significantly improved in processing precision. This improvement enables the machine tool to more accurately control the movement trajectory of the tool when processing complex parts, thereby effectively reducing processing errors. In addition, due to the improvement of processing precision, the product yield is also increased, which means that the quality of the produced parts is higher and the scrap rate is lower. Therefore, the five-axis machine tool of the embodiment of the present application has significant advantages in improving production efficiency and product quality.
