Abstract
The utility model relates to a mechanical disassembling tool, in particular to a pin shaft disassembling tool. The pin shaft disassembling tool comprises a pin pulling oil cylinder and a pin connector, wherein a threaded connecting bushing is arranged at the front end of a piston rod of the pin pulling oil cylinder, the pin connector is arranged at the front end of the threaded connecting bushing, and a screw connector matched with a threaded hole at the end head of the pin shaft is arranged at the front end of the pin connector. The pin shaft which is in interference fit with a workpiece can be conveniently and quickly pulled out by the pin shaft disassembling tool. The pin shaft disassembling tool has the advantages that the property is reliable, the pin shaft cannot be damaged and is convenient and easy to disassemble, the work intensity is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to machinery dismounting frock, specifically is a kind of bearing pin extracting tool.
Background technology
At present, dismounting has the pin of interference fit mainly to adopt hammer and push rod to beat pin out.Doing on the one hand like this, pin is impacted distortion easily or is pulled; There is big, the ineffective problem of labor strength on the other hand.
The utility model content
The utility model is intended to solve the said problem of background technology, and a kind of bearing pin extracting tool that changes traditional method for dismounting, the pin of interference fit is easier to take out is provided.
The technical scheme that the utility model adopts is: a kind of bearing pin extracting tool; Comprise the oil cylinder of pulling pin, pin connector; The piston rod front end of the said oil cylinder of pulling pin is equipped with the cover that is threaded; This front end that is threaded cover is equipped with pin connector, this pin connector front end be provided with the bearing pin termination on the screw rod joint of screwed hole coupling.
Compared with prior art, the beneficial effect of the utility model is: can conveniently extract the bearing pin with the workpiece interference fit, dependable performance is not pulled bearing pin, and is convenient readily removable, reduced labour intensity, improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: bearing pin 1, pin connector 2, the cover 3 that is threaded, big guide 4, the oil cylinder 5 of pulling pin, piston rod 6, oil circuit interface 7, cylinder body 8, open slot 9.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Referring to Fig. 1, the bearing pin extracting tool is made up of pin connector 2, the cover 3 that is threaded, big guide 4, the oil cylinder 5 of pulling pin, and the oil cylinder about 5 of pulling pin respectively has an oil circuit interface 7, to be connected with outside pumping plant.
The said cover 3 one of which ends that are threaded of present embodiment are threaded with the piston rod 6 of the oil cylinder 5 of pulling pin, and the middle part is provided with open slot 9; Said pin connector 2 is a bolt arrangement; Be sleeved on the other end of this cover 3 that is threaded; Its nut end head part is arranged in said open slot 9, and the nut termination can rotate with spanner in open slot 9, so that it is fixing that the screw rod blank area of pin connector 2 is connected with bearing pin 1.
Present embodiment is said, and be threaded cover 3 and pin connector 2 is sleeved in the big guide 4, and this big guide 4 is threaded with the cylinder body 8 of the oil cylinder 5 of pulling pin.
When dismantling the pin axle in the workpiece; Start the piston rod 6 that outside pumping plant stretches out oil cylinder earlier, the screw rod blank area of being convenient to pin connector 2 is connected with the pin axle to be fixed, and starts the piston rod 6 of outside pumping plant withdrawal oil cylinder then; Under the oil cylinder effect; Piston rod 6 drives bearing pin 1 makes it break away from workpiece, dismantles each parts then and takes out bearing pin 1, and the pin axle is extracted by convenient and swift since then.
