Abstract
The utility model relates to a hexagonal spanner, including outer hexagonal prism, interior pressure ram, gasket, nut, interior pressure ram is nested goes into outer hexagonal prism, and in the extrusion syringe needle of interior pressure ram stretched into the working head of outer hexagonal prism, on the pressure ram, it is continuous with the connector of outer hexagonal prism that the nut passes through the gasket, and the screw thread on nut and the interior pressure ram closes the cooperation soon including overlapping gasket and nut in proper order. The utility model discloses simple structure, convenient operation, the quality is light, easily carries. Big power is applyed to the only internal hexagonal bolt head of during operation, can not be to being caused the damage by the connecting piece.
Description
Technical field
The utility model relates to a kind of machine tool of dismantling interior six square bolts, particularly relates to a kind of die nut of interior six square bolts that dismounting head skids.
Background technology
Interior six sides' bolt is a kind of very common mechanical connection part, can be embedded into connected piece inside and connect, thus the effect of accomplishing to save assembly space. But in dismounting when six square bolts, too tight due to the difference of hardness of bolt material or bolt card, skidding and be tending towards circular in bolt head inside, so just causes bolt normally to dismantle. If dismantled by force by the mode of destroying bolt, can there is damage to the screw thread of connected piece or connected piece, do not meet the relevant needs of machinery dismounting.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of die nut is provided, and has solved the problem that interior six square bolts that head skids cannot be dismantled. This spanner can be dismantled not destroying skid interior six square bolt in the situation that, also can not impact connected piece simultaneously, and spanner structure is simple, processing ease, and quality is light, portable.
In order to achieve the above object, the utility model adopts following technical proposals:
A kind of die nut, comprises outer hexagonal prism, interior pressure ram, pad, nut; Described interior pressure ram is nested in outer hexagonal prism, the extruding syringe needle of interior pressure ram stretches in the working head of outer hexagonal prism, successively by pad and nut sleeve on interior pressure ram, nut is connected with the connector of outer hexagonal prism by pad, and nut screws and coordinates with the screw thread on interior pressure ram.
Six working faces of the working head of described outer hexagonal prism are independently cut apart, inner hollow, and the outer surface of working head working face is provided with axial protrusion tooth line; Interior pressure ram is subject to screwing after pressure-acting of nut, and outwards the working head of hexagonal prism pushes, and after the inner pressurized of working head, expands.
Compared with the prior art, the beneficial effects of the utility model are:
Thereby the utility model increases torsional forces by increasing with the extrusion stress of interior six square bolt heads, only apply large pressure at bolt head, therefore can there is not impact to the screw thread of connected piece, skid at dismounting head interior six square bolt time can not destroy bolt, more can not have any impact to connected piece, make intact the disassembling of connected piece.

Fig. 2 is the structural representation of interior pressure ram.
Fig. 3 is outer hexagonal prism structure intention.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described further.
As depicted in figs. 1 and 2, a kind of die nut, comprises outer hexagonal prism 1, interior pressure ram 2, pad 3, nut 4; Described interior pressure ram 2 is nested in outer hexagonal prism 1, the extruding syringe needle 6 of interior pressure ram 2 stretches in the working head 8 of outer hexagonal prism 1, successively pad 3 and nut 4 are enclosed within on interior pressure ram 2, nut 4 is connected with the connector 7 of outer hexagonal prism 1 by pad 3, and nut 4 screws and coordinates with the screw thread 5 on interior pressure ram 2.
As shown in Figure 3, six working faces of the working head 8 of described outer hexagonal prism 1 are independently cut apart, inner hollow, and the outer surface of working head 8 working faces is provided with axial protrusion tooth line; Interior pressure ram 2 is subject to screwing after pressure-acting of nut 4, and outwards the working head 8 of hexagonal prism 1 pushes, and after the inner pressurized of working head 8, expands.
Use procedure of the present utility model is as follows:
The first step, assembling die nut: when the head of interior six square bolts skids can not normally dismantle time, first the working head 8 of outer hexagonal prism 1 is inserted to the head of interior six square bolts, then interior pressure ram 2 is inserted in to outer hexagonal prism 1, again pad 3 is inserted in to interior pressure ram 2 and pad 3 is contacted with connector 7, finally nut 4 is screwed and be inserted in interior pressure ram 2, and contact with pad 3.
Second step, six square bolts in dismounting: take out two common wrench, first spanner blocks the connector 7 of outer hexagonal prism 1, second spanner blocks nut 4, first spanner is motionless, rotate second spanner rotating nut 4, in the screw thread compressing of nut 4, pressure ram 2 makes its axis along outer hexagonal prism 1 move to working head 8, in mobile process, the extruding syringe needle 6 of interior pressure ram 2 can push the working head 8 of outer hexagonal prism 1, it is expanded, and working head 8 just has very large contact force with interior six square bolt heads like this, can not occur skidding when dismounting again. Then can lay down second spanner, reverse first spanner, interior six square bolts are disassembled.
