Description

Technical Field

[0001] The invention belongs to the technical field of bearing processing, and in particular relates to a novel tapered roller bearing inner ring surface strengthening device. Background Art

[0002] Tapered roller bearings are used as shaft supports in many fields such as automobiles, machine tools, construction machinery and railway vehicles due to their strong load-bearing capacity, good lubrication effect and flexible design. In order to further improve the wear resistance, fatigue resistance and corrosion resistance of tapered roller bearings, factories usually use shot peening equipment to perform surface strengthening processing on the inner ring of the bearing during the metal surface treatment of the bearing.

[0003] In terms of shot peening technology, there are related patents. For example, the patent with publication number CN118636064A discloses a shot peening strengthening device for surface treatment of metal materials. A mounting plate is fixedly connected to the inner wall of the shot peening box, and a shot peening table is arranged inside the shot peening box; a rotating adjustment mechanism is fixedly mounted on the mounting plate, and the rotating adjustment mechanism is used to move the workpiece to be processed to one side of the shot peening table. The rotating adjustment mechanism is provided with a fixed component, and the fixed component hoists the workpiece on the rotating adjustment mechanism, and adjusts the position of the workpiece by rotating the rotating adjustment mechanism. This patent places the workpiece into the isolation bin through the rotating adjustment mechanism, completes feeding and discharging inside the isolation bin, and while performing feeding and discharging operations in the isolation bin, other workpieces can be shot peened at the same time, thereby improving the efficiency of shot peening of the workpiece.

[0004] However, the above patent still has the following problems in actual operation:

[0005] The automation level of the equipment is not high, and the workpiece still needs to be placed manually in the shot peening box, and then taken out manually after the shot peening is completed. Secondly, during the shot peening process, since the shot peening table fixes the workpiece in an installed manner, the workpiece has very limited freedom. When shot peening curved workpieces such as the inner ring of a tapered roller bearing, it is difficult to complete all-round shot peening in one go. After completing the shot peening operation on a part of the surface, it is still necessary to manually take it out and adjust the direction, and then re-perform the shot peening operation. In addition, the control freedom of the spray gun and the shot peening table is relatively small, resulting in low processing accuracy and the inability to accurately control the strengthening effect. At the same time, after completing the shot peening, the shot peening machine did not screen and clean the used spray steel balls, and the intact and reusable steel balls were not recycled and used as spray materials for shot peening again. Summary of the invention
