[0002] Sliding bearings are bearings that work under sliding friction. Sliding bearings work smoothly, reliably and without noise. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, which can greatly reduce friction loss and surface wear. The oil film also has a certain vibration absorption ability. However, the starting friction resistance is relatively large. The part of the shaft supported by the bearing is called the journal, and the part that matches the journal is called the bushing. There are two types of bushings: integral and split. The integral bushing is usually called a sleeve. At the same time, both ends of the sleeve need to be chamfered to meet installation requirements.

[0020] Preferably, the method for using the device for chamfering the outer surface of a workpiece for producing and processing a sliding bearing comprises the following steps:

[0021] S1: The electric telescopic rod is retracted to pull the clamping block closer to the clamping frame to fix the bearing ring; then the motor drives the transmission rod to rotate so that the two sliding plates move relative to each other, and at the same time pushes the two spring telescopic tubes and the two spline rods to move relative to each other. When the two spline rods move relative to each other and collide with each other, the two wedge blocks on the right spline rod are inserted into the cross slots to complete the docking of the two spline rods;

[0022] S2: During the docking process of the two spline rods, the three supporting polishing plates on the left side collide with the three supporting polishing plates on the right side to perform annular expansion motion and are supported on the inner wall of the bearing ring;

[0023] After the two spline rods are butted, the two sliding plates continue to move relative to each other and squeeze the four fourth spring compression rods respectively, and the inclined surface at one end of the fourth spring compression rod squeezes the arc plate, so that the arc plate slides inside the groove and drives the squeezing block to contact the outer wall of the bearing ring, further limiting the bearing ring from rotating between the clamping frame and the clamping block;

[0024] S3: Then the transmission rod in the rotating state cooperates with the transmission belt to drive the supporting grinding plate to rotate and grind the inner ring of the bearing ring; then the two sliding plates drive the two spring telescopic tubes to move relative to each other, causing the spring telescopic tubes to compress and push the grinding block in the rotating state to contact and grind the outer ring of the bearing ring, and chamfer it.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In the present invention, the electric telescopic rod is retracted to pull the clamping block toward the clamping frame to fix the bearing ring, and then the two spring telescopic tubes are driven to move relative to each other by two sliding plates, so that the spring telescopic tubes are compressed and push the grinding block in a rotating state to contact and grind the outer ring of the bearing ring, thereby performing chamfering treatment on it.

[0027] In the present invention, when the two spring telescopic tubes are driven by the two sliding plates to move back to back on the two spline rods respectively, the spring telescopic tube changes from a compressed state to a stretched state, and pulls the second spring telescopic rod to extend. At this time, the pulling force applied by the second spring telescopic rod to the hinged plate at its end further increases the supporting force of the supporting grinding plate on the inner wall of the bearing ring, so that the supporting grinding plate drives the bearing ring to rotate between the clamping block and the clamping frame, and the grinding block and the grinding plate inside the clamping frame cooperate to grind the edge of the bearing ring, thereby further removing burrs on the outer wall of the bearing ring.

[0028] In the present invention, during the process of the two spring telescopic tubes sliding back to back, after the outer tube of the right spring telescopic tube hits the T-shaped push rod, the T-shaped push rod is pushed to slide in the cross groove and the pull plate is pulled to the right, so that the two inclined grooves on the pull plate respectively squeeze the two sliders to slide relative to each other, causing the two wedge blocks to disengage from the cross slots, unlocking the two spline rods in the locked state, and then the two spline rods are reset respectively under the action of the reset spring and slide into the corresponding spline sleeves, finally, the electric telescopic rod is extended to pull the clamping block and the clamping frame away, and the bearing ring is removed, and unloading is simple and convenient.

[0055] The use method and advantages of the present invention: The use method of the device for chamfering the outer working surface of a workpiece for producing and processing a sliding bearing, the working process is as follows:

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown:

[0057] S1: When the device is grinding the bearing ring, the bearing to be ground is first placed between the clamping frame 11 and the clamping block 13, and then the clamping block 13 is pulled closer to the clamping frame 11 by contracting the electric telescopic rod 12 to fix the bearing ring;

[0058] S2: Then the motor 4 drives the transmission rod 3 to rotate, and the reciprocating groove 5 on the transmission rod 3 drives the two sliding plates 6 to move relative to each other, thereby driving the two spring expansion tubes 101 to drive the two spline rods 91 to move relative to each other. When the two spline rods 91 move relative to each other and collide with each other, the two wedge blocks 93 on the right spline rod 91 are squeezed by the cross slot 92 and move relative to each other, and then snap into the cross slot 92, completing the docking of the two spline rods 91;

[0059] In the process of docking the two spline rods 91, the three supporting polishing plates 105 on the left spline rod 91 correspond to and abut against the three supporting polishing plates 105 on the right spline rod 91, so that the supporting polishing plates 105 in a group of three perform annular expansion movement and abut against the inner wall of the bearing ring;

[0060] S3: After the two spline rods 91 are connected, the two sliding plates 6 continue to move relative to each other and squeeze the four fourth spring compression rods 116 respectively, and the curved plate 113 is squeezed by the inclined surface at one end of the fourth spring compression rod 116, so that the curved plate 113 slides inside the groove 111 and drives the squeezing block 114 to contact the outer wall of the bearing ring, further limiting the bearing ring from rotating between the clamping frame 11 and the clamping block 13, avoiding the bearing ring from rotating when the grinding block 102 grinds and chamfers the outer ring of the bearing ring, and the grinding plate 117 is driven to move into the clamping frame 11 through the compression of the fourth spring compression rod 116, avoiding the grinding plate 117 from hindering the subsequent grinding block 102 from chamfering the edge of the outer ring of the bearing ring;

[0061] Then, the two sliding plates 6 drive the two spring telescopic tubes 101 to move relative to each other, so that the spring telescopic tubes 101 are compressed and push the grinding block 102 in a rotating state to contact and grind the outer ring of the bearing ring, thereby chamfering the outer ring;

[0062] When the grinding block 102 finishes grinding the outer ring of the bearing ring, the two sliding plates 6 on the transmission rod 3 change from relative movement to opposite movement, so that the sliding plate 6 is separated from one end of the fourth spring compression rod 116. At this time, the fourth spring compression rod 116 is reset to drive the grinding plate 117 to reset, and the arc plate 113 is reset under the action of the third spring compression rod 115 and drives the extrusion block 114 to separate from the outer wall of the bearing ring.

[0063] S4: When the two sliding plates 6 drive the two spring telescopic tubes 101 to move back to each other on the two spline rods 91, the spring telescopic tube 101 changes from a compressed state to a stretched state, and pulls the second spring telescopic rod 104 to extend. At this time, the tension applied by the second spring telescopic rod 104 to the hinged plate 103 at its end further increases the supporting force of the supporting grinding plate 105 on the inner wall of the bearing ring, so that the supporting grinding plate 105 drives the bearing ring to rotate between the clamping block 13 and the clamping frame 11, and the grinding block inside the clamping frame 11 cooperates with the grinding plate 117 on the fourth spring compression rod 116 to grind the edge of the bearing ring, so as to further remove the burrs on the outer wall of the bearing ring;

[0064] When the two spring telescopic tubes 101 slide back to back, the outer tube of the right spring telescopic tube 101 hits the T-shaped push rod 95, pushing the T-shaped push rod 95 to slide in the cross groove 94 and pulling the pull plate 97 to the right, so that the two inclined grooves 98 on the pull plate 97 squeeze the two sliders 99 to slide relative to each other, causing the two wedge blocks 93 to disengage from the cross slot 92, unlocking the two spline rods 91 in the locked state, and then the two spline rods 91 are reset respectively under the action of the reset spring and slide into the corresponding spline sleeves 7, and finally the electric telescopic rod 12 is extended to pull the clamping block 13 away from the clamping frame 11, and then the bearing ring is removed.
