firstly, an operator places a bearing seat to be repaired after being disassembled at a position between two clamping plates (31) at the top end of a second shell (32), keeps the repair surface on the inner side of the bearing seat upward, and then rotates a bidirectional screw rod (33) clockwise through a rotating handle to enable two second nut seats (34) to synchronously move in opposite directions, so that two second sliding blocks (36) on the same second sliding rod (35) are driven to synchronously move in opposite directions, and the two clamping plates (31) clamp and fix the bearing seat in a self-centering manner;
secondly, the bearing seat is sent to the position below the laser repair gun body (5) through the translation mechanism (2), and the servo speed reduction motor (26) is controlled through a control switch to drive the one-way screw rod (22) to rotate clockwise, so that the first nut seat (23) drives the first sliding blocks (25) on the two first sliding rods (24) to synchronously move in the same direction, and the clamping mechanism (3) and the bearing seat on the clamping mechanism are driven to translate to a preset position;
and thirdly, placing the initial position of the laser repairing gun body (5) in a horizontal state, enabling the laser repairing gun body (5) to be repaired from the side edge of the top of the inner side of the bearing seat, simultaneously driving a motor (77) to drive a turntable (75) to rotate, driving a linkage rod (74) to rotate and move along a certain track by the turntable (75), enabling the linkage rod (74) to be matched with a limiting sliding rail (73), driving a rack plate (72) to reciprocate left and right, driving a driving gear (71) to rotate in a reciprocating mode by the same angle by the rack plate (72), enabling an installation rod (6) to be reset after driving the laser repairing gun body (5) to rotate horizontally by 180 degrees along with the driving gear (71), and enabling the installation rod to reciprocate circularly and simultaneously driving the bearing seat to move at intervals by the cooperation of a translation mechanism (2), so that the laser repairing gun body (5) can quickly repair the abrasion of the inner side of the bearing seat.
