[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a rotating disk fixing structure for a spring machine includes a flange 1, mounting bolts 2 are arranged at equal angles on the surface of the flange 1, mounting screw holes 3 for the mounting bolts 2 to be screwed into are opened at equal angles on the surface of the flange 1, a limiting component is arranged at one end opening of the mounting screw hole 3, the limiting component includes a fixing ring groove 4 opened at one end opening of the mounting screw hole 3, a limiting sleeve 5 is arranged inside the fixing ring groove 4, the cross section of the limiting sleeve 5 is "T" shaped, the surface height of the limiting sleeve 5 is less than the inner wall depth of the fixing ring groove 4, and the bottom end surface of the limiting sleeve 5 is aligned with the fixing ring groove 4. A limiting spring 6 is fixed at an equal angle between the inner bottom surfaces of the annular groove 4, a limiting gear ring 7 is installed on the top surface of the limiting sleeve 5, a connecting tooth groove 8 is opened on the top bottom end surface of the mounting bolt 2, the connecting tooth groove 8 is meshed and connected with the limiting gear ring 7, and a fixing plate 9 is symmetrically installed at the edge of the top surface of the limiting sleeve 5. The cross-section of the fixing plate 9 is an inverted "L" shape, which is convenient for further limiting the mounting bolt 2 after installation, so that the mounting bolt 2 is not prone to loose connection after the rotating disk rotates for a long time, which is convenient for improving the firmness of the installation of the mounting bolt 2 and has good practicality.

[0020] like Figure 2 As shown, the inner wall of the mounting screw hole 3 is provided with a functional component, which includes an oil storage ring groove 12 arranged inside the inner wall of the mounting screw hole 3, and a through groove 13 is equidistantly provided on the inner wall of one side of the oil storage ring groove 12, one end of the through groove 13 is communicated with the interior of the mounting screw hole 3, and the through groove 13 is arranged in an inclined shape. An oil filling port 10 is provided on the adjacent surface of the opening at one end of each mounting screw hole 3, and an oil delivery hole 11 is provided on the bottom of the inner wall of one side of the oil filling port 10, and one end of the oil delivery hole 11 is communicated with the interior of the oil storage ring groove 12, and a sealing plug 14 is installed at the opening of the oil filling port 10, and the cross-section of the sealing plug 14 is an inverted isosceles trapezoid, and the side surface of the sealing plug 14 is squeezed and fitted with the inner wall of the opening of the oil filling port 10, so as to facilitate the addition of lubricating oil to the mounting bolt 2 when rust occurs, and the operation is convenient and quick, the functionality is improved, and it is convenient for workers to rotate the mounting bolt 2, and the practical effect is good.

[0021] The utility model provides a rotating disk fixing structure for a spring machine. The specific working principle is as follows: when the mounting bolt 2 needs to be taken out from the inside of the mounting screw hole 3, the surface of the mounting bolt 2 may rust. The worker needs to add lubricating oil to the surface of the mounting bolt 2 before rotating the mounting bolt 2. At this time, the sealing plug 14 needs to be pulled out from the opening of the oil filling port 10, and then lubricating oil is injected into the inside of the oil filling port 10. At this time, the lubricating oil will flow to the inside of the oil storage ring groove 12 through the oil delivery hole 11. At the same time, the lubricating oil in the oil storage ring groove 12 will flow to the surface of the mounting bolt 2 through the through groove 13, which can lubricate the surface of the mounting bolt 2, making it convenient for the worker to rotate the mounting bolt 2. Finally, the sealing plug 14 is snap-fitted and installed at the opening of the oil filling port 10. The operation is convenient and fast, which is convenient to improve the disassembly efficiency of the workers, improves the functionality, and has a good practical effect. When the worker needs to continue to rotate the mounting bolt 2, the end portions of the fixing plates 9 on both sides of the top surface of the limiting sleeve 5 are pressed, so that the limiting sleeve 5 moves toward the inner bottom of the fixing ring groove 4. At this time, the fixing ring groove 4 The limit spring 6 at the bottom of the inner side will generate a certain rebound force, so that the limit gear ring 7 on the top surface of the limit sleeve 5 will lose connection with the connecting tooth groove 8. At this time, the worker can continue to rotate the mounting bolt 2 counterclockwise, so that the mounting bolt 2 can be separated from the inside of the mounting screw hole 3. It is simple and easy to operate. When the mounting bolt 2 is installed inside the mounting screw hole 3, the limit gear ring 7 on the top surface of the limit sleeve 5 is meshed and connected with the connecting tooth groove 8, which can further limit and fix the mounting bolt 2 after installation, so that the mounting bolt 2 will not easily become loose during the rotation of the rotating disk, and the practicality is good.
