Further, said bulb separation pin bottom is provided with spring; Said thimble is ladder to be arranged, and its underpart is provided with spring; Said thimble seat driving mechanism is a cylinder; Said pole driving mechanism is a cylinder; Said outer ring positioning block links to each other with bearing deformation mechanism, and said bearing deformation mechanism comprises cylinder and outer ring push rod, and the outer ring push rod is connected with the push rod of cylinder.
Technique effect of the present invention is:
1. bulb separation pin and bulb separation needle stand are resolved in bulb separation mechanism, and the bulb separation pin is assemblied on the bulb separation needle stand, and manufacturing and installation are easily.
2. adding shock mount on the bulb separation pin, become flexible structure by original rigid construction, adopt the elastic force of spring that the bulb separation pin is risen, is not that hard squeezing driven steel ball, can not cause damage to steel ball.
3. also add shock mount on the thimble, when the bulb separation pin received excessive resistance, this spring shrank, and avoided the bulb separation pin crooked.
4. increased bearing deformation mechanism, made bearing outer ring produce micro-strain, steel ball can freely roll in raceway, and the bulb separation pin can be not stuck, improved bulb separation efficient.
