Purpose of the present invention will provide a kind of not injuring part exactly, and the success rate of pulling pin height is simple to operate, can make alignment pin and bent axle, the more segregative alignment pin pin removal of cylinder body spare.
For achieving the above object, alignment pin pin removal provided by the invention, comprise clamp mechanism, pull pin bolt and be provided with the pilot sleeve of head bore, its special character is: described clamp mechanism comprises the hold-down ring and the cylindrical shape elastic ferrule that is provided with internal thread with at least one clamping screw, described hold-down ring is socketed on the cylindrical shape elastic ferrule outer wall, be provided with vertically a plurality of locking breach on the one end tube wall of described cylindrical shape elastic ferrule, the head bore that the described bolt of pulling pin passes through pilot sleeve is connected with cylindrical shape elastic ferrule inner thread, and the cross section of the described bolt nut of pulling pin is greater than the cross section of head bore.
As preferred version, be provided with vertically the U-shaped chute of the accommodating clamping screw of energy on the described pilot sleeve barrel.
Further, also be provided with the setscrew nut that matches with the bolt of pulling pin, the cross section of described setscrew nut is greater than the cross section of head bore.
Further, the cross section of described head bore is less than the cross section of cylindrical shape elastic ferrule.
Further, described clamping screw is two.
The invention has the advantages that: this pin removal is injuring part not, and the success rate of pulling pin height is simple to operate, and small volume and less weight does not need secondary process, and a people can finish, and can implement to pull out alignment pin whenever and wherever possible.Convenient because of disassembling positioning pin, make roll off the production line, dismantling of engine bent axle, cylinder body can effectively be detected, cleaned, be reprocessed, and provides data and quality guarantee for again utilizing, and has very high promotional value and economic benefit.
