Description

Technical Field

[0001] The utility model belongs to the field of mechanical transmission, and in particular relates to a friction rotating mechanism structure. Background Art

[0002] During the use of a certain bulging machine, it is often necessary to mechanically or manually place the annular workpiece on the work platform, insert the shaping parts, and then perform subsequent actions. After one shaping, it is necessary to mechanically or manually rotate the angle. In this process, there are not only huge safety hazards, but also the rotation angle is different, and the annular workpiece cannot be accurately stressed. After bulging, due to uneven force, the annular workpiece is prone to uneven sizes, which leads to the complexity and uncontrollability of subsequent machining of the annular workpiece.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION

[0016] In order to make the purpose, content and advantages of the utility model clearer, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments.

[0017] This embodiment provides a friction rotation mechanism structure, including: a rotating support roller 1, a mounting seat 2, an end cover 3, a tapered roller bearing 4, a hydraulic synchronous motor 5, and a support roller seat 6;

[0018] The rotating support roller 1 is set as a cylindrical structure, a knurled thread is opened on the side wall of the rotating support roller 1, a supporting roller seat 6 is set at the bottom of the rotating support roller 1, and the end of the rotating support roller 1 is connected to the hydraulic synchronous motor 5 through the tapered roller bearing 4, and the hydraulic synchronous motor 5 provides power support for the rotation of the rotating support roller 1;

[0019] The rotating support roller 1 and the hydraulic synchronous motor 5 are fixed on the working platform of the bulging machine through the mounting seat 2, and the outer part of the tapered roller bearing 4 is fixedly connected to the mounting seat 2 through the end cover 3.

[0020] Wherein, the friction rotation mechanism structure also includes a straight-through pressure injection oil cup 7;

[0021] The straight-through pressure-injection oil cup 7 is arranged above the tapered roller bearing 4 to provide lubricating oil liquid to the tapered roller bearing 4 .

[0022] The knurled thread on the side wall of the rotating support roller 1 is arranged as a segmented structure, which is used to place rings of different diameters according to actual conditions.

[0023] Wherein, the end cover 3 is connected to the mounting seat 2 via M8 bolts.

[0024] The working process is as follows: place the corresponding ring on the rotating support roller so that the bottom of the ring contacts the knurled thread of the rotating support roller. The hydraulic synchronous motor provides the corresponding power for the rotating support roller to rotate it to the corresponding position. The bulging machine correction part provides radial force through the hydraulic cylinder to perform radial expansion movement, so that the annular workpiece on the mold produces circumferential tensile stress, and the diameter of the ring continues to increase. When the stress reaches the yield strength of the material, permanent deformation will occur, so that the diameter of the ring becomes a larger value. The roundness of the ring is improved, and the surface accuracy is close to the accuracy of the mold surface in contact with it. After reaching the required diameter, the ring rotates about 30° and bulges again; then rotates 30° and bulges again. After three bulgings, the bulging is minimized and the roundness of the ring is maximized (note that after a certain period of use, the corresponding lubricating oil is injected from the straight-through pressure injection cup to ensure the lubrication of the tapered roller bearing), which improves the subsequent machining efficiency.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
