[0018] This application discloses an automatic feeding device for a bearing ring grinding machine. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 The automatic feeding device of the bearing ring grinding machine is set on the machine base 1. The machine base 1 is equipped with a grinding machine 11 for grinding bearing rings. A vertical plate 2 is connected to the machine base 1. The vertical plate 2 is located on one side of the grinding machine 11. The upper part of the side of the vertical plate 2 away from the grinding machine 11 is equipped with a feeding rack 21 and the lower part is equipped with a discharging rack 22. The cross-section of the feeding rack 21 and the discharging rack 22 are both U-shaped and the width is adapted to the ring. The side of the vertical plate 2 close to the grinding machine 11 is equipped with a processing part 23 for grinding bearing rings.

[0019] The bottom plate of the discharge rack 22 extends into the interior of the upright plate 2. A baffle 221 is connected to the discharge rack 22. The baffle 221 is located on one side of the bottom plate of the discharge rack 22. A gap is maintained between the baffle 221 and the upright plate 2 to allow the bearing ring to pass through.

[0020] A positioning block assembly 3 is provided on the upright plate 2. The positioning block assembly 3 includes a first positioning block 31, a second positioning block 32, and a third positioning block 33. The first positioning block 31, the second positioning block 32, and the third positioning block 33 are all connected to the upright plate 2 by bolts. The first positioning block 31, the second positioning block 32, and the third positioning block 33 are all located at the end of the discharge rack 22 near the upright plate 2. The first positioning block 31 is set in a vertical direction. The second positioning block 32 and the third positioning block 33 are arranged in an "L" shape. The workpiece can slide vertically down along the side wall opposite to the first positioning block 31 and the second positioning block 32 and fall onto the third positioning block 33.

[0021] A bearing seat 24 is connected to the upright plate 2. A rotating rod 4 is connected inside the bearing seat 24. One end of the rotating rod 4 is connected to a limit block 41, a swing arm 42, and a fixing block 43. The swing arm 42 is located between the limit block 41 and the fixing block 43. Both the limit block 41 and the fixing block 43 are fixedly connected to the rotating rod 4. The swing arm 42 is sleeved on the rotating rod 4. A gripping rod 5 is connected to the top of the swing arm 42. The end of the gripping rod 5 can be inserted into the shaft hole of the bearing ring. A limiting plate 51 is provided, which can abut against the bearing ring. A limiting rod 431 is connected to the fixing block 43. The limiting rod 431 is arranged parallel to the rotating rod 4. The limiting rod 431 passes through the swing arm 42. A limiting hole is opened on the swing arm 42 for the limiting rod 431 to pass through. A pushing cylinder 421 is installed on the swing arm 42. The cylinder body of the pushing cylinder 421 is connected to the swing arm 42. Its piston rod passes through the swing arm 42 and is connected to the fixing block 43.

[0022] After the bearing ring falls onto the third positioning block 33, the swing arm 42 can be moved axially along the limiting rod 431 by pushing the cylinder 421, so that the gripping rod 5 can be inserted into the shaft hole of the bearing ring. The bearing ring can be fixed in conjunction with the limiting plate 51 and the upright plate 2.

[0023] A rotating mechanism 6 is provided on the upright plate 2. The rotating mechanism 6 includes a mounting frame 61, a drive cylinder 62, a wedge block 63, a slider 64, a connecting rod 65, a fixed rod 66, and an auxiliary bearing 67. The mounting frame 61 is connected to the upright plate 2, the drive cylinder 62 is connected to the mounting frame 61, and the wedge block 63 is connected to the mounting frame 61. Two wedge blocks 63 are arranged opposite each other on the mounting frame 61, and a dovetail groove is formed between the two wedge blocks 63. The slider 64 is slidably arranged between the two wedge blocks 63. The piston rod of the drive cylinder 62 is connected to the slider 64. The connecting rod 65 is arranged in an "L" shape. One end of the connecting rod 65 is fixedly connected to the rotating rod 4. The fixed rod 66 is fixedly connected to the connecting rod 65. The fixed rod 66 and the rotating rod 4 are arranged parallel to each other. The auxiliary bearing 67 is connected to the fixed rod 66. The slider 64 has a waist-shaped groove for the auxiliary bearing 67 to move. The inner wall of the waist-shaped groove is in contact with the auxiliary bearing 67.

[0024] During feeding, the slider 64 can be pushed outward by the drive cylinder 62 to move in the dovetail groove. The slider 64 drives the rotating rod 4 to rotate through the connecting rod 65, the fixed rod 66 and the auxiliary bearing 67. The swing arm 42 and the gripping rod 5 on the rotating rod 4 drive the bearing ring to rotate around the rotating rod 4 as the axis. After rotating to the processing section 23, the grinding machine 11 is stopped to perform grinding operations.

[0025] After grinding is completed, the drive cylinder 62 retracts inward, thereby causing the rotating rod 4 to reverse. The gripper pulls the workpiece back. When it moves above the baffle 221, the drive cylinder 62 stops and pushes the cylinder 421 to move the swing arm 42 outward, causing the gripper to disengage from the bearing ring. The processed bearing ring falls between the baffle 221 and the vertical plate 2 and is discharged from the discharge rack 22. Then the drive cylinder 62 starts, driving the gripper rod 5 to continue moving and reset to the third positioning block 33.

[0026] A guide plate 25 is connected to the upright plate 2. The bottom of the guide plate 25 is arc-shaped. When the bearing ring is fed, the bottom of the guide plate 25 can contact the bearing ring, thereby further improving the feeding accuracy of the bearing ring.

[0027] An installation block 26 is connected to the upright plate 2, and an installation rod 261 is connected to the installation block 26. A stop block 2611 is connected to the end of the installation rod 261. When the swing arm 42 is reset, the stop block 2611 can contact the swing arm 42 to rigidly limit the swing arm 42 and ensure the accuracy of the swing arm 42 reset.

[0028] The implementation principle of the automatic feeding device for a bearing ring grinding machine according to an embodiment of this application is as follows: During feeding, the bearing ring rolls from the feed rack 21 to the vertical plate 2. After rolling out of the feed rack 21, it falls onto the third positioning block 33 after being limited by the first positioning block 31 and the second positioning block 32. At this time, the push cylinder 421 drives the swing arm 42 to move axially along the limiting rod 431, so that the gripping rod 5 is inserted into the shaft hole of the bearing ring. The bearing ring is fixed in conjunction with the limiting plate 51 and the vertical plate 2. Then, the drive cylinder 62 extends outward to push the slider 64 to move in the dovetail groove. The slider 64 drives the rotating rod 4 to rotate through the connecting rod 65, the fixed rod 66 and the auxiliary bearing 67. The swing arm 42 and gripping rod 5 on the moving rod 4 drive the bearing ring to rotate around the rotating rod 4 as the axis. After rotating to the processing section 23, the grinding machine 11 stops to perform grinding operations. After the grinding is completed, the drive cylinder 62 retracts inward, thereby driving the rotating rod 4 to reverse. The gripping part carries the workpiece back. When it moves above the baffle 221, the drive cylinder 62 stops and pushes the cylinder 421 to drive the swing arm 42 to move outward, so that the gripping part is separated from the bearing ring. The processed bearing ring falls between the baffle 221 and the vertical plate 2 and is discharged from the discharge rack 22. Then the drive cylinder 62 starts and drives the gripping rod 5 to continue moving and reset to the third positioning block 33.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
