[0002] In the field of precision manufacturing, the five-axis rotary table, as the core component of the machining table, directly determines the machining quality and production efficiency of the workpiece due to its assembly efficiency, structural rigidity and motion accuracy.

[0003] In existing five-axis rotary table machining centers, the rotary table and the bearing used to cooperate with the braking mechanism are mostly designed as separate units, requiring assembly and fixation via bolts, locating pins, and other connecting parts. This structure not only increases the number of parts and assembly steps, but also easily leads to cumulative errors due to assembly gaps, deformation of connecting parts, etc., resulting in a decrease in the coaxiality and rotational accuracy of the rotary table, which in turn affects the dimensional accuracy and surface quality of the workpiece.

[0004] Therefore, there is an urgent need for a machining table solution that can optimize structural design, simplify assembly process and improve overall performance. Utility Model Content

When hydraulic oil is pumped into the ring-shaped hydraulic cylinder, it can hold the outer circle of the hollow retaining shaft for braking.

[0007] Preferably, the outer ring of the rigid-flexible wheel is provided with a through hole, and the bottom of the rotary table is provided with a threaded hole. The bolt passes through the through hole from bottom to top and is threadedly assembled with the threaded hole.

[0008] Preferably, the elastic deformation surface of the aforementioned ring-shaped hydraulic cylinder is close to the outer circular surface of the hollow retaining shaft.

[0009] Preferably, the inner rim of the rigid-flexible wheel described above is fixedly installed on the inner bottom of the cradle by a screw, which runs from bottom to top through the inner bottom of the cradle and is threadedly connected to the bottom of the inner rim of the rigid-flexible wheel.

[0010] Preferably, a motor is fixedly installed on the outer bottom of the cradle, and the motor shaft extends into the cradle and is connected to the rigid-flexible wheel drive through a coupling and a wave generator.

[0011] Preferably, the motor shaft and the coupling are connected by a keyway, the wave generator is fixedly mounted on the coupling, the wave generator is inserted into one end of the rigid-flexible wheel, and the wave generator and the inner circular surface of the rigid-flexible wheel form a transmission fit.

[0012] Implementing the embodiments of this utility model will have the following beneficial effects: After adopting the aforementioned easy-to-assemble processing table; By combining the rotary table and hollow shaft into a single structure, the assembly process of aligning the shaft and rotary table, drilling, and bolting, which are required in traditional separate structures, is eliminated, thus reducing the number of parts and assembly time; that is, simplifying the assembly process and improving assembly efficiency.
