Abstract
A kind of multiplex combination nut, nut 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 its surrounding is axially arranged with multiple and penetrates screwed hole.Interchangeable nut is provided with the manhole, be respectively equipped with screwed hole pushing tow bolt in the multiple penetrating.This multiplex combination nut had both had that pretension speed is fast, uniform accurate advantage, and had the advantages that convenient disassembly, is difficult to loosen, and was engaged by changing the bolt that interchangeable nut can be easily with plurality of specifications size on nut body.
Description
Technical field
The present invention relates to a kind of multiplex combination nut, belong to nut manufacture field.
Background technology
Large-scale nut used by current pretension large-sized bolt, is unicity, i.e., a kind of large-scale nut with large-sized bolt pairing
Can only match with a kind of large-sized bolt of its dimensions identical, large-sized bolt specification changes, and large-scale nut body is necessary
All replacings, waste of resource and manpower.
The content of the invention
For the deficiency that existing large-scale nut is present, the present invention provides a kind of multiplex combination nut, is made up of nut body,
The nut body is made up of oil cylinder and piston, it is characterised in that：The endoporus of the oil cylinder is stairstepping through hole, logical in stairstepping
The cascaded surface in hole 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, described
Piston is the stairstepping cylinder matched with cylinder bore, manhole is axially arranged with the middle of stairstepping cylinder, in circle
Through hole surrounding is axially arranged with multiple and penetrates screwed hole, and interchangeable nut is provided with the manhole, on the top of interchangeable nut
Multiple circular holes are radially provided with periphery, be respectively equipped with screwed hole pushing tow bolt in the multiple penetrating.
The oil groove is respectively provided on two sides with sealing ring up and down.
The top of the pushing tow bolt is in contact with the pad located at cylinder upper end face.
The beneficial effects of the invention are as follows：Both with combination nut pretension speed is fast, pretension is uniform, the accurate advantage of pretension,
There is the interchangeable spiral shell by changing different size specification on nut body again
Mother, can make a nut body realize being engaged pretension with the pretension bolt of multiple different size specifications, save material
With manufacturing cost.

Specific embodiment
As depicted in figs. 1 and 2, the invention provides a kind of multiplex combination nut, it is made up of nut body, the nut sheet
Body is made up of oil cylinder 1 and piston 2.The endoporus 11 of the oil cylinder 1 is stairstepping through hole, and oil is provided with the cascaded surface of stairstepping through hole
Groove 12, the oilhole 13 communicated with oil groove 12 is provided with the bottom of oil groove 12, joint 14 is radially provided with oilhole 13, in the oil groove
About 12 are respectively provided on two sides with sealing ring 15；The piston 2 is the stairstepping cylinder matched with 1 endoporus of oil cylinder 11, in ladder
Manhole 21 is axially arranged with the middle of shape cylinder, being axially arranged with multiple in the surrounding of manhole 21 penetrates screwed hole 22.Institute
State manhole 21 and be provided with interchangeable nut 23, multiple circular holes 231 are radially provided with the top periphery of interchangeable nut 23.
The multiple penetrating is respectively equipped with pushing tow bolt 24 on screwed hole 22, the top of pushing tow bolt 24 with located at the upper surface of oil cylinder 1
Pad 16 is in contact.
