Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
As shown in figure 1, the rotary supporting device for drilling is matched with a Z3080 rocker drill to perform chamfering of a mounting hole on the end face of an oversized bearing and tapping of a connecting threaded hole, so that the problem of processing of rotary supports of large megawatt bearing rings is solved. The rotary support ring comprises a circular rotary support ring 1, and it should be noted that the rotary support ring 1 can adopt a scrapped bearing ring with the diameter of 4 meters, and a workbench for installing and clamping the bearing ring with the diameter of 3 meters to 6 meters can be formed. A plurality of supporting components 2 are uniformly distributed at the bottom of the rotary supporting ring 1, the supporting components 2 support the rotary supporting ring 1 and drive the rotary supporting ring to rotate, a workpiece supporting frame 3 is fixed at the upper part of the rotary supporting ring 1, and the workpiece supporting frame 3 is a plurality of supporting ribs distributed in a scattering shape. An oversized bearing or a bearing ring is placed on the bearing support device, and the bearing support device is supported in a rotating mode through the support component 2. In the actual operation process, the machined workpiece is placed on the I-shaped steel, and the machining requirement of the workpiece can be met because the machined workpiece is heavy and the cutting amount of the machined part of the workpiece is small.
Specifically, as shown in fig. 1 and 2, four support assemblies are arranged and distributed at 90 degrees. The supporting component 2 comprises a bracket 2.1 and a rotating wheel 2.2; the support 2.1 is connected with a rotating wheel 2.2 in a rotating mode, the rotating wheel 2.2 contacts the bottom surface of the rotary supporting ring 1, the bottom surface of the rotary supporting ring 1 is in tangent fit with the rotating wheel 2.2 of the supporting assembly 2, and the rotating wheel 2.2 rotates and drives the rotary supporting ring 1 on the rotating wheel 2.2 to rotate. The structure utilizes the friction force between the rotary support ring 1 and the rotating wheel 2.2 to transmit torque between the rotary support ring and the rotating wheel. There are many ways for the supporting component to drive the rotary supporting ring to rotate, for example, the rotating wheel is replaced by a gear, and the bottom surface of the rotary supporting ring 1 is processed with meshing teeth matched with the gear so as to ensure the transmission relationship between the two. As shown in fig. 4 and 5, the upper part of each supporting component 2 is rotatably connected with a limiting wheel 2.3, the limiting wheels are horizontally arranged and are in tangential fit with the inner surface of the rotary supporting ring 1, and the plurality of limiting wheels 2.3 ensure that the rotary supporting ring 1 rotates concentrically.
To supporting component 2's structure, its similar horseshoe form can more reliably support the device, and support 2.1 rotates the installation through the bearing and rotates the wheel including rotating wheel fixed part and bottom integrated into one piece's trapezoidal platform supporting part on the wheel fixed part, rotates the wheel, and trapezoidal platform supporting part outside-in runs through the fretwork, and the weight of whole device can also be alleviateed under the prerequisite of reliable support has been guaranteed to such hollow out construction. As shown in fig. 1, one of the plurality of support assemblies 2 is a power support assembly 4, and a rotating wheel of the power support assembly 4 is connected with a rotary driving motor 4.1. The power support assembly 4 is similar in structure to the power support assembly 2. The difference is that the rotating wheel of the power supporting component 4 is a driving wheel 4.2, the driving wheel 4.2 is driven by a motor to rotate, the surface of the driving wheel 4.2 is knurled and quenched, and the rolling friction force of the surface of the driving wheel 4.2 on the end surface of the rotary supporting ring 1 is increased. Ensuring the rotation torque of the driving wheel 4.2.
