Abstract
A kind of multiplex assembling bolt, bolt body is made up of oil cylinder and piston.The cylinder bore is stairstepping through hole, and oil groove is provided with stairstepping through hole cascaded surface, and the oilhole communicated with oil groove is provided with oil groove bottom, and sealing ring is respectively provided on two sides with up and down in oil groove；The piston is the stairstepping cylinder matched with cylinder bore, and manhole is axially arranged with the middle of cylinder, and being axially arranged with multiple in manhole surrounding penetrates screwed hole.Interchangeable bolt is provided with the manhole, be respectively equipped with screwed hole pushing tow bolt in the multiple penetrating.This multiplex assembling bolt had both had that pretension speed is fast, the uniform accurate advantage of pretension, and had the advantages that to be engaged with the screwed hole or large-scale nut of the big machinery part of plurality of specifications size by changing interchangeable bolt.
Description
Technical field
The present invention relates to a kind of multiplex assembling bolt, belong to bolt manufacture field.
Background technology
Large-sized bolt used by current pretension big machinery part, in the screwed hole with big machinery part or large-scale nut phase
Timing, is single raw pairing, i.e., a kind of large-sized bolt can only be with the screwed hole of its dimensions identical big machinery part
Or large-scale nut matches, when the screwed hole or large-scale nut dimensions of big machinery part change, large-sized bolt sheet
Body must be changed all, waste of resource and manpower.
The content of the invention
For the deficiency that existing large-sized bolt is present, the present invention provides a kind of multiplex assembling bolt, and it is by bolt body group
Into.It is characterized in that：The bolt body is made up of oil cylinder and piston.The cylinder bore is stairstepping through hole, in stairstepping
Through hole cascaded surface is provided with oil groove, and the oilhole communicated with oil groove is provided with oil groove bottom, and joint is radially provided with oilhole, in institute
State oil groove and be respectively provided on two sides with sealing ring up and down；The piston is the stairstepping cylinder matched with cylinder bore, in stairstepping
Manhole is axially arranged with the middle of cylinder, being axially arranged with multiple in manhole surrounding penetrates screwed hole.Described circular logical
Hole is provided with interchangeable bolt, and hexagon ring is provided with the top of interchangeable bolt.Be respectively equipped with screwed hole top in the multiple penetrating
Bolt is pushed away, the top of pushing tow bolt is in contact with the pad located at cylinder upper end face respectively.
The beneficial effects of the invention are as follows：Both there is quick, uniform, accurate pretension, and
With the dimensions by changing interchangeable bolt on bolt body, realize that a bolt body can be with multiple big machineries
The screwed hole or large-scale nut of part match, the advantage saved material with manufacturing cost.
