DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model embodiment provides an ultra-high frequency oilstone swing mechanism for ultra-finishing bearing grooves, such as Figure 1-Figure 5 As shown, it includes a driving motor 1 and a rotating motor 4; a mounting box 2 is provided on one side of the driving motor 1, a swing structure 3 is provided inside the mounting box 2, an adjusting structure 6 is provided on one side of the mounting box 2, a fixing block 5 is provided on the top of the adjusting structure 6; a chuck 7 is provided at the front end of the fixing block 5, and a rotating motor 4 is provided at the rear end of the chuck 7.

[0024] Specifically, in this embodiment: when processing the bearing, by setting the swing structure 3, the oilstone 306 can be made to swing back and forth faster, and by setting the adjustment structure 6, the position of the bearing can be adjusted through the fixed block 5, making it more convenient during processing.

[0025] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the adjustment structure 6 includes a mounting frame 601, a servo motor 602, a screw 603 and a screw sleeve 604. The mounting frame 601 is arranged on one side of the mounting box 2. The screw 603 is arranged inside the mounting frame 601, and the screw sleeve 604 is arranged outside the screw 603. The top of the screw sleeve 604 is connected to the bottom end of the fixed block 5. The servo motor 602 is arranged on one side of the mounting frame 601. The output end of the servo motor 602 extends to the inside of the mounting frame 601. The output end of the servo motor 602 is connected to one side of the screw 603. The outer side of the screw 603 is provided with an external thread, and the outer side of the screw sleeve 604 is provided with an internal thread. A threaded connection is formed between the screw 603 and the screw sleeve 604.

[0026] Specifically, in this embodiment: when processing the outer groove of the bearing, the bearing is installed on the chuck 7, and the servo motor 602 is started after the installation is completed. After starting, the servo motor 602 will drive the screw 603 to rotate. When the screw 603 rotates, it will drive the fixed block 5 to move through the screw sleeve 604, thereby indirectly driving the bearing to adjust its position, so that it can be used for bearings of different sizes during processing. When the outer side of the bearing contacts one side of the oilstone 306, it stops moving, thereby completing the adjustment work.

[0027] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the swing structure 3 includes a connecting rod 301, a connecting shaft 302, a limiting groove 303, a limiting ring 304, an inclined wheel disc 305 and an oil stone 306.

The limiting ring 304 is arranged on the outer side of one end of the connecting rod 301, and the oil stone 306 is arranged at the other end of the connecting rod 301. The inner diameter of the limiting groove 303 is larger than the outer diameter of the connecting rod 301, and the limiting groove 303 and the connecting rod 301 form a movable connection. Two groups of limiting rings 304 are arranged, and the two groups of limiting rings 304 are symmetrically distributed on one side of the connecting rod 301.

[0028] Specifically, in this embodiment, after the adjustment is completed, the rotating motor 4 is started to drive the chuck 7 to rotate. When the chuck 7 is rotating, the driving motor 1 is started. After starting, the driving motor 1 will drive the bevel wheel 305 to rotate through the connecting shaft 302. When the bevel wheel 305 rotates, it will drive the connecting rod 301 to move back and forth through the limit ring 304, thereby driving the oilstone 306 to perform an ultra-high frequency reciprocating swing, so that one side of the oilstone 306 contacts the outside of the rotating bearing at a high frequency, thereby completing a processing work on the groove on the outside of the bearing.
