[0001] This utility model relates to the field of five-axis rotary table technology, specifically a five-axis rotary table with a double tilting axis driven roller cam. Background Technology

[0002] In today's high-end machining field, with the increasing demands for precision and efficiency in the machining of complex workpieces from industries such as aerospace, automobile manufacturing, and mold processing, five-axis rotary tables, as key equipment capable of multi-angle, high-precision machining, play a vital role. They enable workpieces to achieve complex spatial movements during machining, thereby meeting the machining needs of various complex-shaped workpieces and greatly expanding the technological scope and capabilities of machining. Currently, the common roller cam structure five-axis rotary tables on the market mainly consist of an inclined axis, a rotary axis, and a tailstock. This traditional structure can basically meet the machining requirements when machining workpieces of general weight and size. With its relatively simple structure and convenient motion control, it has been applied to a certain extent in the machining industry.

[0003] However, when faced with heavy and large workpiece machining tasks, the limitations of traditional roller cam structure five-axis rotary table become apparent. During the machining process, the tailstock usually only serves to support the workpiece and does not have the function of outputting power. This means that the weight of the entire workpiece and the various torques generated during the machining process are almost entirely borne by the tilt axis. As the weight and size of the workpiece increase, the load on the tilt axis increases sharply, and the load rate remains high. Utility Model Content

The rotary axis 16 is mounted on the tilting axis A15 and the tilting axis B17, and the tilting axis A15 and the tilting axis B17 are provided with a dual-motor drive structure.

[0025] In the specific implementation process, the rotary shaft 16 is installed on the corresponding bearing parts of the tilting shaft A15 and the tilting shaft B17 to ensure assembly accuracy. The dual-motor drive structure is started so that the tilting shaft A15 and the tilting shaft B17 move according to the set parameters, driving the rotary shaft 16 to achieve complex five-axis rotation.

[0026] See Figure 2 and Figure 3As shown, the tilting shaft B17 includes a turret 5, a bearing 4, and a tilting shaft housing 3. The turret 5 is locked onto the bearing 4, and the bearing 4 is locked onto the tilting shaft housing 3. A transition ring 2 is locked above the turret 5. The tilting shaft B17 is provided with a brake ring 6 and an oil supply ring 7. The brake ring 6 is locked onto the oil supply ring 7, and the oil supply ring 7 is locked onto the tilting shaft housing 3. The brake ring 6 achieves braking and releasing the brake by clamping or releasing the turret 5. The tilting shaft B17 is provided with a clamp 9, a bearing seat 10, and a camshaft 8. The clamp 9 is locked onto the bearing seat 10, and the brake ring 6 is locked onto the camshaft 8. The rotating shaft 16 is connected to the tilting shaft B17 through the transition ring 2.

[0027] In the specific implementation process, firstly, the bearing 4 is precisely installed into the designated installation position on the tilting shaft housing 3 and secured with high-strength bolts to ensure a stable connection between the bearing 4 and the tilting shaft housing 3 and that the concentricity meets design requirements. Next, the turret 5 is carefully placed on the bearing 4 and securely locked to it, ensuring that the turret 5 can rotate smoothly under the support of the bearing 4. Then, the adapter ring 2 is installed above the turret 5, and suitable fasteners are used to tightly connect the adapter ring 2 to the turret 5, ensuring no loosening at the connection point. The oil supply ring 7 is installed into the pre-designed position on the tilting shaft housing 3 and secured with locking screws to ensure good sealing between the oil supply ring 7 and the tilting shaft housing 3, preventing lubricant leakage. Finally, the brake ring 6 is installed onto the oil supply ring 7 and secured, ensuring a firm connection between the brake ring 6 and the oil supply ring 7. After installation, the braking system is initially tested to check whether the brake ring 6 can properly clamp or release the turret 5 to achieve the braking and releasing functions. The bearing housing 10 is installed into the corresponding position of the tilting shaft B17 and fixed. Then, the clamp 9 is installed onto the bearing housing 10 and locked onto the bearing housing 10 with bolts and other fasteners to ensure that the clamp 9 can move flexibly. Then, the camshaft 8 is installed into the tilting shaft B17 and the brake ring 6 is locked onto the camshaft 8 to ensure a reliable connection between the camshaft 8 and the brake ring 6. The connecting end of the rotating shaft 16 is connected to the adapter ring 2 above the turret 5 on the tilting shaft B17. High-precision connectors are used to tightly connect the two together to ensure that the coaxiality between the rotating shaft 16 and the tilting shaft B17 after connection meets the design requirements to ensure the smoothness and accuracy during rotation.

[0028] See Figure 4 As shown, the tilting shaft B17 is equipped with a motor 11 and a motor plate 12.

The pinion 13 is connected to the drive shaft of the motor 11, and the large gear 14 is fixedly connected to the turret 5. The tilting shaft A15 and the tilting shaft B17 have symmetrical and similar structures.

[0029] In the specific implementation process, high-strength bolts are used to lock the motor plate 12 onto the inclined shaft housing 3. Then, appropriate bolts are used to lock the motor 11 onto the motor plate 12. The pinion 13 is installed onto the drive shaft of the motor 11, ensuring that the pinion 13 and the drive shaft are tightly connected without any looseness. The large gear 14 can be installed onto the turret 5 using key connections or expansion sleeve connections, and it is fixed firmly with bolts and other fasteners to ensure that the coaxiality of the large gear 14 and the turret 5 meets the requirements to guarantee transmission accuracy.

[0030] Working principle:

[0031] Step 1: Install the rotating shaft 16 onto the corresponding bearing positions of the tilting shafts A15 and B17, ensuring assembly accuracy. Use high-precision connectors to tightly connect the rotating shaft 16 to the adapter ring 2 above the turret 5 on the tilting shaft B17, ensuring coaxiality meets design requirements. Precisely install the bearing 4 into the designated position on the tilting shaft housing 3 and lock it in place, ensuring a stable connection and meeting concentricity requirements. Place the turret 5 on the bearing 4 and lock it in place, ensuring smooth rotation. Install the adapter ring 2 on top of the turret 5 and connect it tightly. Install the oil supply ring 7 into the pre-designed position on the tilting shaft housing 3 and fix it in place, ensuring good sealing. Install the brake ring 6 onto the oil supply ring 7. After installation, the braking system is initially tested and its function is checked. The bearing housing 10 is installed and fixed in the corresponding position of the tilting shaft B17. The clamp 9 is installed on the bearing housing 10 and locked to ensure that the clamp 9 can move flexibly. The camshaft 8 is installed inside the tilting shaft B17. The brake ring 6 is locked on the camshaft 8 to ensure reliable connection. The motor plate 12 is locked on the tilting shaft housing 3. The motor 11 is locked on the motor plate 12. The pinion 13 is installed on the drive shaft of the motor 11. The large gear 14 is installed on the turret 5 and fixed firmly to ensure that the coaxiality meets the requirements. The tilting shaft A15 and the tilting shaft B17 have symmetrical and similar structures.

[0032] Step 2: Start the dual-motor drive structure. Motor 11 runs and drives the pinion 13 to rotate. The pinion 13 is driven by the transition gear 18 and the large gear 14 in sequence, so that the tilting shaft A15 and the tilting shaft B17 move according to the set parameters, thereby driving the rotating shaft 16 to achieve complex five-axis rotation.
