s3, driving a motor 37 to operate so as to drive a rolling forming head 38 to rotate to roll and process the sliding bearing piece, and operating an external negative pressure device to absorb scraps generated in the rolling process through a scraps collecting cover 10, wherein the absorbed scraps are discharged into an external collecting box from a scraps conveying pipe 11 through a scraps collecting frame 9;
S4, when the support column 20 is damaged or the adjustment range of the arc-shaped top supporting plate 28 is not in accordance with the specification of the sliding bearing piece, the bearing fixing assembly 4 is replaced, the clamping column 25 is pressed to enable the sliding plate 23 to move inside the sliding groove 22 to squeeze the pressing spring 24, the limit of the clamping column 25 by the operation hole 18 is released, the threaded connection relation between the rotating support column 20 and the threaded sleeve 21 and the fixing frame 17 is contacted, and the bearing fixing assembly 4 is taken out from the top of the fixing frame 17 to be replaced.
In step S1, the method further includes the steps of:
S11, controlling the first electric telescopic rod 27 to work through the controller 12, pushing the first electric telescopic rod 27 to enable the first electric telescopic rod 27 to contact with the inner ring of the sliding bearing piece and prop the inner wall of the sliding bearing piece, monitoring the distance between the first electric telescopic rod 28 and the inner ring of the sliding bearing piece by the distance sensor 43, transmitting a signal to a receiving module of the controller 12 by the distance sensor 43 after the distance reaches a propping fixed position, controlling the first electric telescopic rod 27 to stop working by the control module, and ensuring the propping stability of the first electric telescopic rod 28 by the buffer spring 30;
in step S2, the method further includes the steps of:
s21, a worker rotates the stud 45 to enable the reinforcing ring 46 to be screwed inwards, the wear-resistant layer 47 is in contact with the outer side of the positioning column 39, and the reinforcing ring 46 carries out limit clamping on the positioning column 39;
in step S3, the method further includes the steps of:
S31, after the rolling processing of the sliding bearing piece is finished, the electric telescopic rod I27 and the electric telescopic rod II 40 are reset in sequence to release the limiting clamping of the sliding bearing piece, and a worker performs blanking operation on the processed sliding bearing piece.
When the device is used, firstly, a sliding bearing piece to be processed is placed on a placing disc 41, a limiting groove 42 is matched with the sliding bearing piece in size to limit the sliding bearing piece, so that preliminary fixing of the sliding bearing piece is realized, an electric telescopic rod II 40 works to push the placing disc 41, the placing disc 41 ascends and enables an inner ring of the sliding bearing piece to be positioned at the outer side of the top end of a supporting column 20, the electric telescopic rod I27 is controlled to work through a controller 12, the electric telescopic rod I27 pushes an arc-shaped supporting plate 28 to be in contact with the inner ring of the sliding bearing piece and supports the inner wall of the sliding bearing piece, a distance sensor 43 monitors the distance between the arc-shaped supporting plate 28 and the inner ring of the sliding bearing piece, after the distance reaches a supporting fixed position, the distance sensor 43 transmits signals to a receiving module of the controller 12, the control module controls the state of the electric telescopic rod I27 to stop working, and a buffer spring 30 ensures the supporting stability of the arc-shaped supporting plate 28;
The electric sliding block 14 moves on the sliding rail seat 13 to drive the processing table 16 to adjust the position in the horizontal direction, the rolling forming mechanism 5 starts to move when the bearing fixing assembly 4 moves right below the rolling forming head 38, the adjusting motor 33 moves to drive the threaded rod 32 to rotate, the threaded rod 32 rotates to enable the bearing block 34 to slide inside the bracket 31, the bearing block 34 drives the rolling forming head 38 to move downwards until the positioning column 39 is inserted inside the positioning hole 7, the worker rotates the stud 45 to enable the reinforcing ring 46 to be screwed inwards, the wear-resisting layer 47 contacts with the outer side of the positioning column 39, the reinforcing ring 46 carries out limit clamping on the positioning column 39, the driving motor 37 moves to drive the rolling forming head 38 to rotate to carry out rolling processing on the sliding bearing piece, external negative pressure equipment moves to absorb scraps generated in the rolling process through the scraps collecting cover 10, the scraps are discharged into the external collecting box from the scraps conveying pipe 11 through the scraps collecting box 9, the electric telescopic rod I27 and the electric telescopic rod II 40 are reset in sequence after the processing of the sliding bearing piece is finished, and the worker carries out blanking operation on the sliding bearing piece after processing;
When the support column 20 is damaged or the adjustment range of the arc-shaped top supporting plate 28 is not in accordance with the specification of the sliding bearing piece, the bearing fixing assembly 4 is replaced, the clamping column 25 is pressed to enable the sliding plate 23 to move inside the sliding groove 22 to squeeze the pressing spring 24, the limit of the clamping column 25 by the operation hole 18 is released, the threaded connection relation between the contact thread bush 21 of the support column 20 and the fixing frame 17 is rotated, and the bearing fixing assembly 4 is taken out from the top of the fixing frame 17 to be replaced.
