the clamping driving assembly 621 drives the extrusion table 622 to reciprocate, so that the extrusion table 622 acts on the positioning element 623, and the inner diameter surface of the bearing to be detected is positioned, clamped or separated by utilizing the deformation of the positioning element 623.
In this embodiment, the positioning member 623 is disposed at the top end of the positioning rod 615, and the extrusion table 622 is disposed on the side of the positioning member 623 away from the end of the positioning rod 615, when in use, the inner ring of the bearing to be detected is sleeved between the positioning rod 615 and the extrusion table 622, and the outer diameter of the positioning rod 615 is smaller than or equal to the inner diameter of the inner ring of the bearing to be detected, and the outer diameter of the extrusion table 622 is smaller than or equal to the inner diameter of the inner ring of the bearing to be detected, so that when the power output end of the clamping driving assembly 621 pulls the extrusion table 622 to move to the side of the positioning member 623, the positioning member 623 will deform, and the deformation force of the deformation will face the inner diameter side of the inner ring of the bearing to be detected, so that the positioning member 623 compresses the inner diameter surface of the inner ring of the bearing to be detected, and when the bearing positioning seat 614 rotates, the inner ring of the bearing to be detected, which is connected to the positioning rod 615 in a compressing manner can be driven.
Preferably, the clamping driving assembly 621 comprises a driving cylinder 6211, a piston 6212 inserted in the driving cylinder 6211, a piston rod 6213, a spring 6214 on a side far from the piston rod 6213, and a pneumatic connector 6215; the spring 6214 is connected to the inner wall of the driving cylinder 6211 corresponding to the piston 6212, the pneumatic connector 6215 is connected to the inner cavity wall formed by the piston 6212 and the driving cylinder 6211 on one side of the piston rod 6213, one end of the piston rod 6213 is connected to the piston 6212, and the other end of the piston rod 6213 is connected to the pressing table 622.
In this embodiment, during the process of driving the pressing table 622 by the clamping driving assembly 621 to move back and forth, gas is injected through the pneumatic connector 6215, the pressure between the piston 6212 located at one side of the piston rod 6213 and the inner cavity wall of the driving cylinder 6211 increases, so as to push the piston 6212 to move towards the spring 6214 side, and compress the spring 6214, at this time, the pressing table 622 presses against the positioning member 623, so that the positioning member 6423 presses against the inner diameter surface of the bearing to be detected, and when the injected gas is discharged through the pneumatic connector 6215, the piston 6212 is subjected to the elastic force of the spring 6214, so that the pressing table 622 moves towards the side far away from the positioning member 623, the deformation of the positioning member 623 is recovered, and the deformation force generated by the bearing to be detected by the positioning member 623 disappears, at this time, the bearing to be detected can be conveniently removed from the positioning rod 615.
Preferably, the positioning member 623 is a member made of silicone rubber.
In the present embodiment, the positioning member 623 made of silicone rubber can be deformed after being pressed by the pressing table 622, and when the pressing force disappears, the positioning member 623 can be quickly deformed and restored.
