Working principle: when the self-propelled tooth jump detection device for the slewing bearing is used, as shown in Figs. 1-3, if installation. positioning and rotating movement control of the slewing bearing are needed. the slewing bearing is placed outside the limiting table 6 on the top of the positioning table 4: after the circuit where the motor 3 and the electromagnets 33 are located is imported. in order to make the motor 3 rotate in the forward and reverse directions. the flowing direction of current is changed; and when the motor 3 rotates in the forward direction. the iron cores 12 generate S pole magnetism after the current is imported into the electromagnets 11. Because the S pole magnetism on the iron cores 12 and the magnetism of the permanent magnets 9 arc the same. the S pole magnetism repels with the magnetism of the permanent magnets 9. so as to change the distance between the limiting table 6 and the positioning rubber blocks 7. The first connecting rods 8 rotate and the rubber cylinder 10 is deformed. so that the positioning rubber blocks 7 squeeze and position the inner wall of the slewing bearing; the slewing bearing is well fixed on the positioning table 4. and the motor 3 drives the positioning table 4 and the slewing bearing for rotating movement, so that the slewing bearing carries out the subsequent walking tooth jump detection. Through the installation of the conductive copper ring 5, the electromagnets 11 rotate with the limiting table 6 without power failure. When the motor 3 rotates in the reverse direction, after the current is imported into the clectromagnets 11. N pole magnetism generated by the iron cores 12 is different from the magnetism of the permanent magnets 9 to produce an adsorption eflect to facilitate the installation and separation of the slewing bearing on the limiting table 6.
As shown in Fig. 1 and Figs. 4-7. when the screw runner 14 is manually rotated. the screw runncr 14 is in threaded connection with the bottom of the positioning frame 15, so that the positioning frame 15 and the fixed pipe 13 shde relatively and the distance among the positioning cylinder 16, the structure thereof and the slewing bearing is changed. The standard gear shaft 19 is meshed with the side of the installed and positioned slewing support. When the slewing bearing rotates, the teeth on the slewing bearing are meshed with the standard gear shaft 19. so that the standard gear shaft 19 pushes the telescopic rod 17 and the positioning cylinder 16 to perform relative telescopic movement. The telescopic rod 17 and the limiting rod 21 move axially and simultancously. Under the pushing of the standard gear shaft 19 and the clastic action of the first elastic members 22, the limiting rod 21 reciprocates and is meshed with the fine gear 25: the detection data size information of the tooth jump is enlarged under the connection action of the meshing sawteeth of the limiting rod 21 and the fine gear 25. so that the fine gear 25 drives the middle shaft 24 and pointer 26 to perform reciprocating rocking movement. Under the alignment action of the pointer 26 and the dial indicator scale disc 23 and under the action of the difference data of the rocking movement amplitude of the pointer 26, the tooth jump frequency and tooth jump distribution distance of the slewing bearing are detected. For the abnormal position of the tooth jump. the cotton brush head 30 is used to mark the abnormal position of the tooth jump of the slewing bearing through the relative telescopic movement of the circular pipe 27 and the push rod 28. Through the arrangement of the fine hole
32. the cotton brush head 30 can absorb the paint in the paint cylinder 31 effectively without causing permeation and leakage in the paint cylinder 31.
