Abstract
A kind of assembling bolt, its bolt body is made up of oil cylinder and piston.The cylinder bore is stairstepping through hole, and oil groove is provided with the cascaded surface of stairstepping through hole, and sealing ring is respectively provided on two sides with up and down in oil groove；The upper piston area is the stairstepping cylinder matched with cylinder bore, and bottom is bolt thread.Circumferentially it is axially arranged with multiple in the cylindrical end face and penetrates screwed hole, penetrating the oilhole that is axially arranged with the inside of screwed hole and is communicated with oil groove, be respectively equipped with screwed hole pushing tow bolt in the multiple penetrating.This assembling bolt has the advantages that quick, uniform, accurate pretension big machinery part, and convenient disassembly, and pretension is not required to permanent seal pressurize and special pre- clamping tool.
Description
Technical field
The present invention relates to a kind of assembling bolt, belong to bolt manufacture field.
Background technology
Large-sized bolt used by current pretension big machinery part mainly has two kinds：One kind is common large-sized bolt, its structure
Simply, but pretension bother, it is necessary to could be by its pretension by special pre- clamping tool；Second is large-scale pushing tow bolt, its application
Common pre- clamping tool just can be accurate by its pretension, pretension, is difficult to loosen, but pretension speed is slow, dismantles more difficult.
The content of the invention
For the deficiency that existing large-sized bolt is present, the present invention provides a kind of assembling bolt, and it is made up of bolt body.Its
It is characterised by：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 sealing ring is respectively provided on two sides with up and down in oil groove；The upper piston area is to match with cylinder bore
Stairstepping cylinder, bottom is bolt thread.Circumferentially it is axially arranged with multiple in the stairstepping cylindrical end face and penetrates screw thread
Hole, is axially arranged with the oilhole communicated with oil groove on the inside of screwed hole, and multiple circular holes are radially provided with periphery on the outside of screwed hole.
Be respectively equipped with screwed hole pushing tow bolt in the multiple penetrating, pushing tow bolt end head connects with the pad located at cylinder upper end face
Touch.
The beneficial effects of the invention are as follows：Both there is quick, uniform, accurate pretension big machinery part, had had again
The remarkable advantage that loosening, convenient disassembly, pretension are not required to long term seal pressurize and special pre- clamping tool is difficult after pretension.

Specific embodiment
As depicted in figs. 1 and 2, the invention provides a kind of assembling bolt, be made up of bolt body, the bolt body by
Oil cylinder 1 and piston 2 are constituted.The endoporus 11 of the oil cylinder 1 is stairstepping through hole, and oil groove is provided with the cascaded surface of stairstepping through hole
12, sealing ring 13 is respectively provided on two sides with about 12 in oil groove；The top of the piston 2 is the stairstepping matched with 1 endoporus of oil cylinder 11
Cylinder, bottom is bolt thread.Circumferentially it is axially arranged with multiple in the stairstepping cylindrical end face and penetrates screwed hole 22,
Penetrate the inner side of screwed hole 22 and be axially arranged with the oilhole 23 communicated with oil groove 12, radially set on the outside periphery of screwed hole 22 is penetrated
There are multiple circular holes 21.Pushing tow bolt 24 is respectively equipped with screwed hole 22 in the multiple penetrating, the top of pushing tow bolt 24 with set
Pad 14 in the upper surface of oil cylinder 1 is in contact.
Claims (1)
