Description
1, affiliated technical field
The utility model relates to a kind of multistage push fastener of pretension large-scale workpiece.
2, background technique
At present, the pretension large-scale workpiece, the large-scale bolt or the nut that generally all adopt special device such as hydraulic elongator, hydraulic torque wrench or the direct pretension of special tool to be loaded on the workpiece are realized.Under the situation of no special device or special tool, just can not be with the large-scale workpiece pretension; Prevent loosening main methods such as spring washer, cotter pin or double nut, the poor reliability of adopting of workpiece.
3, summary of the invention
For overcoming at present under the situation of no special device or special tool, can not be the drawback of large-scale workpiece pretension, and raising prevents the reliability that workpiece is loosening, the utility model provides a kind of multistage push fastener, this multistage push fastener only need just can be easily with the large-scale workpiece pretension with the common manual torque wrench, and can prevent reliably that it from becoming flexible.
The scheme of the utility model technical solution problem is: the pretension large-scale workpiece, adopt a kind of multistage push fastener, and it is made up of cylindrical stud bolt, loose-proof self-lock nut, super pad, multistage push swivel nut and multistage push bolt.Cylindrical stud bolt, its centre is made cylindrical, and screw thread is made at two.On one head thread of cylindrical stud bolt super pad and loose-proof self-lock nut are housed.Super pad is contained in the inboard, and the one side contacts with workpiece.Loose-proof self-lock nut is contained in the outside, and 1.5 ° the special conical surface is made in its bottom, is used to prevent that workpiece is loosening.At its barrel surface, radially be drilled with a plurality of blind holes that equal angles distributes, be used to insert pole; Super pad and multistage push swivel nut are housed on the other end screw thread of cylindrical stud bolt.Super pad is contained in the inboard, and the one side contacts with workpiece.The multistage push swivel nut is contained in the outside, and the multistage push bolt is housed above it, and an end of multistage push bolt contacts with super pad.When the pretension large-scale workpiece, at first pole is inserted in the blind hole of the loose-proof self-lock nut on cylindrical stud bolt one head thread, with manual methods it is twisted by super pad, again pole is inserted in the blind hole of the multistage push swivel nut on the screw thread of cylindrical stud bolt other end, with manual mode it is twisted by super pad, repeatedly tighten multistage push bolt on the multistage push swivel nut one by one with manual torque wrench then, rely on all multistage push bolts withstand on the contacted super pad of workpiece on to axial jacking force that cylindrical stud bolt produced, realization is with the purpose of large-scale workpiece pretension, and loose-proof self-lock nut can prevent the loosening of large-scale workpiece effectively simultaneously.
The beneficial effects of the utility model are: when the pretension large-scale workpiece, do not need special device or special tool, only the common torque wrench of needs just can be fastening with large-scale workpiece easily, and can prevent effectively that it is loosening, fastening convenient and swift, time saving and energy saving, economic security.
