Abstract
The utility model discloses an assembly and disassembly tool for a stud. The assembly and disassembly tool for the stud comprises the stud, a lead screw, a lead screw wrench, a sleeve, sleeve wrenches and a nut, wherein the screw lead wrench perpendicularly penetrates through a hole in the upper end of the lead screw, the lower portion of the lead screw penetrates through a hole in the middle of the sleeve and is in threaded connection with the sleeve, the sleeve wrenches perpendicular to the sleeve are arranged on the two sides of the sleeve, the lower end of the sleeve penetrates into the upper end of the nut, the nut and the sleeve are fixed though fastening screws on the two sides, the upper portion of the stud penetrates through the nut and is in threaded connection with the nut, and the upper end face of the stud makes tight contact with the lower end face of the lead screw. By the mode, the assembly and disassembly tool can rapidly screw and unscrew the stud, damage to threads is avoided, and working efficiency is improved. The assembly and disassembly tool is simple and practical in design structure, convenient to manufacture, flexible in use, easy to repair and capable of reducing working difficulty.
Description
Technical field
The utility model relates to bolt mounting or dismounting tools field, particularly relates to a kind of stud mounting or dismounting tools.
Background technology
Stud, is also studs.For connecting mechanical fixed-link function, there is screw thread at two, and centre is screw rod.Be generally used for mining machinery, bridge, automobile, motorcycle, boiler steel structure, tower crane, large-span steel and heavy construction etc.Stud is arranged on equipment, first two nuts will be installed successively on one end of stud, the nut outside then pulling with spanner is arranged on the other end of stud on equipment, then two nuts are unloaded successively.When needs stud when equipment disassembles, two nuts need to be installed successively equally on one end of stud, then the nut inside pulling with spanner unloads the other end of stud from equipment, two nuts are unloaded successively, installation, the demounting procedure of stud are loaded down with trivial details again, and the mounting or dismounting of troublesome poeration, the stud of wasting time and energy are inconvenience very, existing mode mostly is handmade rotary mounting or dismounting, waste time and energy, operating efficiency is extremely low, and easily damages screw thread.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of stud mounting or dismounting tools, can conveniently carry out installation and removal to stud, has avoided screw thread damage, improved operating efficiency, its project organization is simple and practical, easy to make, and easily repair, reduce work difficulty.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of mounting or dismounting tools of stud, comprise stud, the mounting or dismounting tools of described a kind of stud comprises leading screw, leading screw spanner, sleeve, box spanner and nut, described leading screw spanner vertically passes the hole of leading screw upper end, described leading screw bottom is through the hole in the middle of sleeve, be connected with bush whorl, described sleeve both sides are provided with the box spanner vertical with sleeve, nut upper end is stretched in described sleeve lower end, nut and sleeve are fixed by the trip bolt of both sides, described stud top is through nut, be connected with nut thread, described stud upper surface and leading screw lower surface close contact.
Preferably, described leading screw is connected with the left-handed fine thread of sleeve.
The beneficial effects of the utility model are: a kind of stud mounting or dismounting tools of the utility model, can conveniently carry out installation and removal to stud, and avoid screw thread damage, improved operating efficiency, its project organization is simple and practical, easy to make, and easily repair, reduce work difficulty.
Brief description of the drawings
Fig. 1 is the structure cutaway view of a kind of stud assembly and Disassembly special tool of the utility model;
Fig. 2 is the structural representation of a kind of stud assembly and Disassembly special tool of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1, leading screw; 2, sleeve; 3, nut; 4, leading screw spanner; 5, box spanner; 6, holding screw; 7, stud.
Detailed description of the invention
Below in conjunction with accompanying drawing, to the utility model, preferred embodiment is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to accompanying drawing 1 to Fig. 2, the utility model embodiment comprises:
A kind of mounting or dismounting tools of stud, comprise stud 7, the mounting or dismounting tools of described a kind of stud comprises leading screw 1, leading screw spanner 4, sleeve 2, box spanner 5 and nut 3, the vertical hole through leading screw 1 upper end of described leading screw spanner 4, described leading screw 1 bottom is through the hole in the middle of sleeve 2, be threaded with sleeve 2, described sleeve 2 both sides are provided with the box spanner vertical with sleeve 25, nut 3 upper ends are stretched in described sleeve 2 lower ends, nut 3 and sleeve 2 are fixing by the trip bolt 6 of both sides, described stud 7 tops are through nut 3, be threaded with nut 3, described stud 7 upper surfaces and leading screw 1 lower surface close contact.By rotating threaded shaft 1, make leading screw 1 lower surface and stud 7 upper surfaces produce frictional force, drive stud 7 to rotate.Described leading screw 1 is connected with the left-handed fine thread of sleeve 2.Described nut 3 is made according to thread standard seriation, meets different studs and coordinates requirement.
Concrete operation step is:
Mounting stud: select nut 3 consistent with the screw thread specification of wanted mounting stud 7, be fastenedly connected by holding screw 6 and sleeve 2, rotating threaded shaft spanner 4, adjusting screw 1 height, by stud 7 precession nuts 3, until stud 7 upper end contact with leading screw 1 lower end surface, hold box spanner 5, the internal thread hole of aiming at installation site turns clockwise, and utilizes the frictional force of stud 7 and leading screw 1 end face, realizes the installation of stud 7.
Dismounting stud: select nut 3 consistent with the screw thread specification of wanted mounting stud 7, be fastenedly connected by holding screw 6 and sleeve 2, rotating threaded shaft spanner 4, adjusting screw 1 height, hold box spanner 5, nut 3 holes are aimed to precession clockwise on the stud 7 that is about to remove, until stud 7 upper end contact with leading screw 1 lower end surface, holding leading screw spanner 4 is rotated counterclockwise, leading screw 1 declines, leading screw lower end surface tightly suppresses stud 7 upper end, producing frictional force drives stud 7 to be rotated counterclockwise, until screw out, complete stud 7 dismantlement works.
A kind of stud assembly and Disassembly special tool of the utility model, conveniently carries out installation and removal to stud, has avoided screw thread damage, has improved operating efficiency, and its project organization is simple and practical, easy to make, and easily repairs, and has reduced work difficulty.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
