[0025] Example:

[0026] A large five-axis turntable with auxiliary support comprises a first fixed seat 1 and a second fixed seat 2, wherein a first reducer 3 is arranged at the upper end of the first fixed seat 1, and a second reducer 4 is arranged at the upper end of the second fixed seat 2, a rotating component 5 is rotatably connected between the first reducer 3 and the second reducer 4, a workbench 6 for clamping a workpiece is arranged at the top end of the rotating component 5, and a supporting component 7 for auxiliary support is also connected to the bottom end of the workbench 6.

[0027] It is explained that installing auxiliary supports can share part of the force of the five-axis turntable, reduce the wear of the key components of the turntable, and thus extend the service life of the turntable. In addition, auxiliary supports can also reduce the risk of failure caused by overload of the turntable and improve the reliability of the equipment.

[0028] Combined with the accompanying drawings Figure 1-Figure 3The rotating component 5 includes a first rotating seat 51, a second rotating seat 52, a turntable bracket 53 and a first connecting seat 54. The first rotating seat 51 is rotatably connected to the first reducer 3, and the second rotating seat 52 is rotatably connected to the second reducer 4. The turntable bracket 53 is arranged between the first rotating seat 51 and the second rotating seat 52. The first connecting seat 54 is arranged on the bottom surface of the turntable bracket 53 and is connected to the supporting component 7.

[0029] It is explained that the turntable bracket 53 in the five-axis turntable is a key component for supporting and fixing the turntable. The turntable bracket 53 not only ensures the stability of the turntable when it rotates or moves at high speed, but also ensures the accuracy and reliability of the turntable system. First of all, the turntable bracket 53 provides a stable support for the turntable. When rotating at high speed or bearing heavy loads, the turntable bracket 53 can effectively disperse and withstand various forces from the turntable to prevent the turntable from deformation or displacement. This stability ensures that the turntable will not vibrate or deflect during operation, thereby ensuring the accuracy and quality of the work.

[0030] Specifically, the turntable bracket 53 plays an important role in maintaining the balance of the turntable system. Since the five-axis turntable involves the linkage and complex movement of multiple axes, the design and manufacture of the turntable bracket 53 must be precise to ensure the balance and stability of the entire turntable system. Only by ensuring the balance of the turntable can the safety and efficiency of the equipment during operation be ensured. In addition, the turntable bracket 53 also has the function of protecting the turntable and extending its service life. During the operation of the equipment, the turntable bracket 53 can effectively reduce the impact and wear on the turntable, thereby extending the service life of the turntable. This not only reduces the maintenance cost of the equipment, but also improves the overall economic benefits of the equipment.

[0031] It is further worth explaining that the workbench 6 includes a second connecting seat 61 and a clamping plate 62, the second connecting seat 61 is rotatably connected to the top surface of the turntable bracket 53, the clamping plate 62 is fixedly connected to the top surface of the second connecting seat 61, and the top surface of the clamping plate 62 is also provided with a plurality of clamping grooves.

[0032] It is explained that the workbench 6 is the bearing component in the five-axis turntable, which is responsible for fixing and supporting the gravity and cutting force of the workpiece. It must have sufficient rigidity and stability to withstand the various forces and moments generated during the processing or measurement process to ensure the accuracy and precision of the workpiece. Secondly, the workbench 6 is also responsible for realizing the precise positioning and rapid transposition of the workpiece. Through a precise control system, the workbench 6 can perform high-precision movements in five axial directions to realize rapid positioning and precise adjustment of the workpiece. At the same time, the workbench 6 also has a variety of transposition functions to meet the needs of processing or measuring different workpieces.

[0033] Specifically, the clamping slots on the five-axis rotary table are designed for precise fixation and positioning of workpieces. The design of the clamping slots takes into account a variety of workpiece shapes and sizes, so it is highly versatile and flexible. Whether it is a round, square or irregularly shaped workpiece, you can find a suitable clamping method. In short, the clamping slots on the five-axis rotary table are an important part of the five-axis rotary table. It provides stable and precise fixation and positioning for the workpiece, allowing the five-axis rotary table to perform at its best in various complex working environments.

[0034] Combined with the accompanying drawings Figure 1-Figure 3 The supporting component 7 is a hydraulic cylinder. When the hydraulic cylinder is not in operation, it is in a suspended state. The supporting component 7 includes a cylinder housing 71 and a piston 75. One end of the piston 75 is connected to the first connecting seat 54, and the other end of the piston 75 is slidably arranged inside the cylinder housing 71. A first oil port 72 and a second oil port 73 are provided on the cylinder housing 71. The first oil port 72 is opened near the first connecting seat 54, and the second oil port 73 is opened near the lower end of the cylinder housing 71. A pair of springs 74 for vibration reduction and resetting are also provided at the bottom of the cylinder housing 71.

[0035] It is explained that in this application, the hydraulic cylinder is used as an auxiliary support structure of the five-axis turntable, which can effectively prevent the risk of deformation or even breakage of the turntable bracket when the turntable is subjected to a large load. In addition, the main advantages of the hydraulic cylinder as an auxiliary support are reflected in the following aspects: First, it can significantly enhance the stability of the turntable. Through its powerful thrust, the hydraulic cylinder provides a solid support foundation for the five-axis turntable, so that it can effectively reduce vibration and shaking when it runs at high speed or bears heavy loads, thereby ensuring the high precision and stability of the turntable. Secondly, the hydraulic cylinder can share the load borne by the five-axis turntable. Compared with traditional mechanical support methods, the hydraulic cylinder has significant advantages in sharing the load. When the hydraulic cylinder is subjected to pressure, it can evenly transfer the force to each support point of the five-axis turntable, effectively dispersing the total load borne by the turntable. In addition, the hydraulic cylinder itself has high rigidity and stability, and can withstand large loads and impact forces. At the same time, the hydraulic cylinder also has the characteristics of self-lubrication and wear resistance, which can significantly extend the service life of the equipment, reduce maintenance costs, and improve overall operating efficiency.
