Abstract
The utility model discloses an installation tool for a double-end stud, and relates to the technical field of installation tools for the double-end stud. The installation tool for the double-end stud comprises a sleeve, a nut and a nut fixing mechanism. The problem that the installation tool is scrapped due to damage to an internal thread of the installation tool can be solved through the method of replacing the nut. The nut, a flat gasket and a check ring for holes are sequentially installed and fixed in the sleeve. When the nut is damaged, the check ring for the holes is dismounted, the damaged nut is replaced by a new nut, and the new nut continues to be used on an original tool body. The installation tool for the double-end stud is high in installation efficiency, the nut of the tool body can be replaced, and therefore the sleeve can be used repeatedly.
Description
Technical field
The utility model relates to studs erecting tools field.
Background technology
Studs is a kind of of securing member, and it must complete the link of more than two parts through twice assembling ability fastening nut, reaches the purpose of fastening parts.The particularity of studs is: after loading on matrix by it, just become pile, pile has guidance quality, is easy to the sealing gasket that the string cover need to embed in two parts junctions, guarantees the sealing after two parts assemble.The assembling of studs, need to just can complete by special instrument.The general method adopted of people is mainly to adopt on studs first relatively to tighten double nut, then pulling nut by spanner is assembled to studs on workpiece, this mode is complex operation not only, work efficiency is low, and the screw thread that studs tightens the nut place also easily is subject to the extruding of external force and deformation occurs.The studs spanner that use is also arranged in the market is all machining internal thread on body of tool basically, and such specific purpose tool repeatedly can cause the internal thread serious wear afterwards in use, thereby whole instrument is scrapped.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of erecting tools that can the Fast Installation studs, and after this instrument nut thread serious wear, it is convenient to change, and sleeve can Reusability, has therefore reduced cost.
For solving the problems of the technologies described above, a kind of studs erecting tools the utility model proposes, comprise the fixed mechanism of sleeve, nut, nut.In sleeve, bottom is provided with the fixed mechanism of nut, and the fixed mechanism of nut comprises plain cushion and hole back-up ring; Described sleeve is divided into three layers, is from top to bottom: ground floor is driving hole, and the second layer is nut bore, and the 3rd layer is circular hole, and the circular hole bottom has groove; Hold-down nut in driving hole, place plain cushion, fixing hole back-up ring in groove in circular hole.
Adopt above technical scheme: sleeve and nut combinations, nut bore and nut shape are coincide, and nut position in sleeve is fixed by nut bore; In the fixed mechanism of nut, plain cushion is positioned at the nut below, increase the contact area that the nut lower end is fixed, the studs erecting tools is when tightening studs, nut can be subject to the downward reaction force of studs, under this active force, nut has the trend that breaks away from sleeve, and the purpose of plain cushion is to increase the nut lower end and the stress surface between back-up ring for hole; With back-up ring at the fixed mechanism of nut bottom, hole is fixed in groove with back-up ring, blocks main plain cushion in hole.After nut damages, take off the hole back-up ring, taking-up plain cushion and nut, replace with new nut, puts plain cushion, with Circlip tongs, hole inserted with back-up ring in the groove of fixed mechanism of nut.
Adopt the beneficial effect that technique scheme produces to be: in the situation that do not scrap whole body of tool, change fast the nut of damage, be reassembled into new body of tool, it is convenient to change, and sleeve can Reusability, has therefore reduced cost.In use, use the utility model directly to tighten studs, thereby reduce the installation time of studs.In use, because spanner does not directly contact nut, nut is fixed in sleeve inner and is not subject to outside damage, thus reduce the damage ratio of studs screw thread in installation process.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1;
In figure, 1 sleeve, 11 driving holes, 12 nut bore, 13 circular holes, 14 grooves, 2 nuts, 3 plain cushions, 4 hole back-up rings.
The specific embodiment
The studs erecting tools that the utility model proposes, comprise the fixed mechanism of sleeve 1, nut 2, nut 2.The interior bottom of sleeve 1 is provided with the fixed mechanism of nut 2, and the fixed mechanism of nut 2 comprises plain cushion 3 and back-up ring 4 for hole; Described sleeve 1 is divided into three layers, is from top to bottom: ground floor is driving hole 11, and the second layer is nut bore 12, the 3rd layer is circular hole 13, and circular hole 13 bottoms have groove 14, the interior hold-down nut 2 of driving hole 11, the interior placement plain cushion 3 of circular hole 13, the interior back-up ring 4 for fixing hole of groove 14.Sleeve 1 and nut 2 combinations, the interior lower nuts hole 12 of sleeve 1 and nut 2 shapes are coincide, and nut 2 is fixed in nut bore 12; In the fixed mechanism of nut 2, plain cushion 3 is positioned at nut 2 belows, increase the contact area that nut 2 lower ends are fixed, the studs erecting tools is when tightening studs, nut 2 can be subject to the downward reaction force of studs, under this active force, nut 2 has the trend that breaks away from sleeve 1, and the purpose of plain cushion 3 is to increase nut 2 lower ends and the stress surface between back-up ring 4 for hole; With back-up ring 4 at the fixed mechanism of nut 2 bottom, hole is fixed in groove 14 with back-up ring 4, blocks main plain cushion 3 in hole.
After nut 2 damages, with Circlip tongs, hole is taken off with back-up ring, take out plain cushion 3 and nut 2, replace with the new nut 2 matched with installed studs, put plain cushion 3, with Circlip tongs, hole is inserted with back-up ring 4 in the groove 14 of fixed mechanism of nut, the studs erecting tools both can come into operation again.
