Description
Technical field
The utility model relates to securing member process equipment field, has particularly related to a kind of hexagonal fluting self-locking nut 6 closing devices.
Background technology
High strength hexagonal fluting self-locking nut belongs to a kind of effective torque lock type whole metal self-locking nut, and it has two kinds of anti-loose structures simultaneously---effective torque anti-loose structure and mechanical fixed-type external anti-loose structure.When this serial nut and bolts assemblies, owing to receiving pressure, internal thread is out of shape, when crushed element internal thread and bolt thread screw, be subject to the extruding of bolt thread and restore to the original state, thus make internal thread produce elastic deformation and elastic deformation force, the interference effect of elastic deformation force creates the moment of friction of the relative rotary motion stoping screw bolt and nut, thus it is locking to realize effective torque.After installation, the locking groove on nut aims at the cotter-pin hold of bolt, and screw thread pair is fixed by the split pin penetrating dimension, thus realizes mechanical fixed-type external loosening configuration.
Adopt the form that two kinds of above-mentioned anti-loose structures combine, the anti-loosening property of this serial nut is very stable, reliable, makes it be often used for important connecting portion.Therefore, this serial nut is widely used in the military industry fields such as Aero-Space, is not only widely used in the civil area such as machinery, automobile, and have also been obtained in aerospace field and apply widely.
Although hexagonal fluting self-locking nut is handy, but but comparatively plain nut is more complicated for its procedure, the complexity of procedure is mainly manifested in the closing in link in production procedure, the more difficult control of this production link, closing up to add easily there is the defects such as locking torque is defective, locking torque is unstable man-hour.Therefore, how effectively to control the locking torque of hexagon slotted nut, ensure properties of product reliable and stable be a difficult problem in this serial nut processing.
Summary of the invention
The purpose of this utility model is to provide a kind of hexagonal fluting self-locking nut 6 closing devices, to solve the unmanageable problem of hexagonal fluting self-locking nut crimping link.
In order to solve the problem, hexagonal of the present utility model slots self-locking nut 6 closing devices by the following technical solutions: hexagonal fluting self-locking nut 6 closing devices, comprise alignment pin and closing in pushing-pressing arm, alignment pin comprises the closing-up machine location division for coordinating with the table positions of closing-up machine of lower end, the nut location division for processed nut location fit of upper end and between closing-up machine location division and nut location division, for the stopper section with processed nut counter stopper, closing in pushing-pressing arm comprises the pressing portion for pushing processed nut for the connecting portion that coordinates with closing-up machine and front end of rear end, described pressing portion be provided with processed nut by the V-arrangement locating slot of closing in position external shape fits.
The bottom land of described V-arrangement locating slot tilts backwards from top to bottom.
Be provided with the step surface of face forward on the downside of the front end of described pushing-pressing arm, step surface makes the front end of pushing-pressing arm form cantilever design, and the front end place of described cantilever design is located at by V-arrangement locating slot.
Because hexagonal fluting self-locking nut of the present utility model 6 closing devices include described alignment pin and pushing-pressing arm, therefore, when in use, by alignment pin, processed nut is assemblied in the setting position of closing-up machine, then by V-arrangement locating slot and the due-in port part location fit of processed nut of pushing-pressing arm, coordinate the circumferential uniform stressed that just can ensure processed nut with closing-up machine by three pushing-pressing arms simultaneously, just the amount of contraction of processed nut corresponding site can be controlled by the active strokes adjusting pushing-pressing arm, thus solve the unmanageable problem of hexagonal fluting self-locking nut crimping link.
Further, it is in order to after processed nut crimping that the bottom land of V-arrangement locating slot is tilted backwards from top to bottom, and V-arrangement locating slot still can be fitted with its corresponding site, also can play the effect limiting processed nut crimping degree simultaneously; The setting of cantilever design pushes post-brachial intensity to ensure, avoids pushing-pressing arm front end blocked up simultaneously and cause interference to closing in process.

Detailed description of the invention
The embodiment of hexagonal fluting self-locking nut 6 closing devices, as Figure 1-5, this hexagonal fluting self-locking nut 6 closing devices comprise alignment pin 11 and closing in pushing-pressing arm 12.
In the present embodiment, the shape of alignment pin 11 in three grades of multidiameters, it comprises the path section of the central diameter section on top, the large footpath section at middle part and bottom, the central diameter section of its middle and upper part constitutes for the nut location division 111 with processed nut location fit, when in use, nut location division 111 can and the internal face of processed nut 13 between matched in clearance; Middle part large footpath section define stopper section 112, use process in, after processed nut 13 overlaps top nut location division 111, stopper section 112 can with processed nut 13 counter stopper, prevent it from falling further; Path section constitutes closing-up machine location division 113, and closing-up machine location division is used for workbench 14 location fit of closing-up machine to limit the position of processed nut 13.
Pushing-pressing arm 12 comprises the connecting portion 121 of rear end and the pressing portion 122 of front end, wherein connecting portion 121 is for coordinating the main shaft pushing-pressing arm to be fixed on closing-up machine with closing-up machine, pressing portion 122 is for directly pushing the corresponding site of processed nut 13 to order about its distortion of closing up, pressing portion 122 is provided with V-arrangement locating slot 123, V-arrangement locating slot is adopted to be in order to adaptive with the corresponding site of processed nut 13, in the present embodiment, the bottom land of V-arrangement locating slot 123 tilts backwards from top to bottom, this still can keep and its close contact after shrinking at the corresponding site of processed nut 13, with the degree of shrinkage at the processed nut crimping position of limit.In addition, be provided with the step surface of face forward on the downside of the front end of pushing-pressing arm 12, step surface makes the front end of pushing-pressing arm form cantilever design, and the front end place of described cantilever design is located at by V-arrangement locating slot.In the present embodiment, pushing-pressing arm has three, can three pushing-pressing arms be assemblied on the main shaft of closing-up machine in 120 ° between any two during use, as shown in Figure 1, wherein in figure, arrow represents the direction of the power that closing-up machine applies, after pushing once, by processed nut integral-rotation 60 °, pushing can complete the closing in of processed nut again.
