Background technology
In prior art, be usually welded on alignment pin by electric welding by the screw mated with pin removal, extracted by alignment pin with pin removal, waste time and energy, during electric welding, weldering is spent and is easily burnt out by part.Meanwhile, electric welding machine needs to be equipped with specially, and when operation department does not have electric welding machine, need outer please professional's cooperation focusing on, pending part was often because depositing easy-to-rust for a long time.When installation operates, workman installs alignment pin can there is unusual condition unavoidably, once occur that unusual condition bent axle scrappage is higher; At engine new product development, when repairing under engine quality evaluation or fault machine, owing to filling alignment pin thus causing dismantling of engine bent axle, cylinder body effectively can not detect, reprocess and clean, cause dismantling of engine bent axle, cylinder body do not detect data, maybe cannot reprocess, clean, can not be reused and cause waste.
Summary of the invention
Object of the present invention will provide one not injuring part exactly, and success rate of pulling pin is high, simple to operate, can make alignment pin and bent axle, the more segregative alignment pin pin removal of cylinder body part.
For achieving the above object, alignment pin pin removal provided by the invention, comprise clamp system, to pull pin bolt and be provided with the pilot sleeve of head bore, its special character is: described clamp system comprise with at least one clamping screw hold-down ring and establish female cylindrical shape elastic ferrule, described hold-down ring is socketed on cylindrical shape elastic ferrule outer wall, one end tube wall of described cylindrical shape elastic ferrule is provided with multiple locking breach vertically, described bolt of pulling pin is connected with cylindrical shape elastic ferrule inner thread by the head bore of pilot sleeve, the cross section of described bolt nut of pulling pin is greater than the cross section of head bore.
Preferably, described pilot sleeve barrel is provided with vertically the U-shaped chute of the accommodating clamping screw of energy.
Further, be also provided with the setscrew nut matched with 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 not injuring part, success rate of pulling pin is high, simple to operate, and small volume and less weight does not need secondary process, and a people can complete, and can implement whenever and wherever possible to pull out alignment pin.Because disassembling positioning pin is convenient, make to roll off the production line, dismantling of engine bent axle, cylinder body effectively can be detected, clean, reprocess, provide data and quality guarantee for again utilizing, there is very high promotional value and economic benefit.
