Furthermore, a screw hole or a nut body for screwing the ejector rod is arranged on the second plate body.
Furthermore, a straight groove from the bottom to the upper part is formed in the second plate body opposite to the clamping groove; an H-shaped sliding block is arranged in the straight groove in a sliding manner; the H-shaped sliding block is provided with a screw hole or a nut body which is screwed with the ejector rod; an end block is integrally formed at the top of the outer side of the H-shaped sliding block; a lifting screw is screwed on the end block; a bolt seat is screwed on the lifting screw; the bolt seat is fixed on the outer side of the second plate body, the bolt seat is screwed on the lifting screw rod, meanwhile, the lifting screw rod is screwed on the end block, circular motion of the lifting screw rod is converted into linear sliding of the H-shaped sliding block, and therefore the ejector rod on the H-shaped sliding block can slide up and down, and the ejector rod is tightly pressed against the center of the end part of the shaft body of the bearing to be disassembled.
Compared with the prior art, the utility model discloses a special frock is dismantled to forced air cooling line roller bearing base has following advantage:
1. the working efficiency is improved, and the time spent by detaching the steel tube from the original steel tube is reduced to 5 minutes from 10 minutes.
2. The condition that the on-spot greasy dirt is many has been overcome, because of frock trompil size and roller head size block, the condition that also does not have the greasy dirt and skid has improved the operating rate greatly.
3. Safe and reliable has avoided slipping in the instrument use to lead to the instrument to jump out, has protected staff's operation safety.
