Description
Technical field
The present invention relates on a kind of pressing end face and arrange reeded new type nut, it is applicable to the rugged environment being in vibration for a long time, impacting, and can be applicable to engineering machinery, railway locomotive, harbour machinery, bridge works, textile manufacturing machine etc.
Background technique
For solving the antivibration of threaded fastener, anti-loose, scheme conventional at present adopts spring washer, nylon embeds, pin, distortion screw thread, the methods such as mighty bond is bonding, they loosen voluntarily although can delay threaded fastener to a certain extent, the time come off, but cannot tackle the problem at its root, particularly wherein using scope is the widest, consumption is maximum, the good spring washer of antivibration effect, be in the rugged environment of vibratory impulse for a long time, continuous appearance is because of separation of scattering after spring washer brisement, come off and the accident caused, historical facts or anecdotes can not be satisfactory in using.
Summary of the invention
Be in the rugged environment of vibratory impulse for a long time to overcome the existing threaded fastener being furnished with spring washer, separation of scattering is there is after cannot overcoming the spring washer brisement on it, the shortcoming such as come off, a kind of structure of special proposition is simple, easy to use, can according to the concrete needs of the spring washer of different size, its pressing end face is provided with there is reasonable depth and geometrical shape the geometric form groove that can protect this spring washer (even if there is brisement and the situation of scattering in this spring washer, this groove also can guarantee the brisement body on this spring washer to protect and the brisement body that can not occur on spring washer is separated with threaded fastener the caused accident that comes off) a kind of pressing end face on reeded new type nut is set, to make up current deficiency.
For achieving the above object, technological scheme of the present invention is achieved in that and a kind of pressing end face arranges reeded new type nut, the pressing end face that it is characterized in that this new type nut is provided with at least one match with spring washer can prevent spring washer brisement after scatter and be separated, the geometric form groove come off, described pressing end face and geometric form groove thereof screw by the externally threaded cooperation of the same bolt matched of the internal thread of this new type nut match with the described spring washer be enclosed within bolt and put in place and rely on the flange on geometric form groove to be encircled for protection by spring pad, with reach prevent spring washer brisement after to scatter separation, the object come off.
Preferably, described geometric form groove preferably has the circular groove that the degree of depth is 1.6 ~ 28 millimeters.
Certainly, the geometric form groove that the pressing end face of described new type nut is arranged, both can be arranged on the pressing end face of nut, can also be arranged on the pressing end face of bolt head; Described geometric form groove can have multiple geometrical shape, can be the shapes such as circular, square, interior hexagon, interior octagon, wherein circular best, and can select the different degree of depth from spring washer Proper Match as required; The degree of depth of described geometric form groove is preferably consistent with the degree of depth of the flange on described geometric form groove; The profile of this new type nut can have multiple geometrical shape, and can be circular, square, the shape such as hexagon, butterfly, wherein hexagon be best.
According to the present invention, a kind of pressing end face arranges reeded new type nut, its working principle and using method are that by the threaded end contraposition on the bolt that mates with this nut, through the matching hole of connected piece, (this matching hole can select circle as required on request, square, double-U-shaped, the pass that rectangle etc. are different), then spring washer contraposition is put in the geometric form groove that the pressing end face of this nut is arranged, again the pressing end face one end contraposition matching this nut of above-mentioned spring washer is packed into and screws in the threaded end on bolt, namely finally screw this nut and put in place installs (even if be in vibratory impulse for a long time, the rugged environment of exposing to the sun and rain, above-mentioned spring washer is caused to occur brisement and the situation of scattering, due to the protective action of the flange on geometric form groove, therefore geometric form groove can be guaranteed the brisement body of above-mentioned spring washer to protect and stop the brisement body occurred on spring washer and be separated with threaded fastener the caused accident that comes off).When need unload, first this nut derotation unclamped and can unload by anti-installation procedure operation.
A kind of pressing end face being arranged reeded new type nut can by multiple material, as carbon steel, stainless steel, aluminum alloy, macromolecular material etc. are made, by kinds of processes, as the methods such as die forging, cold-heading, die casting, injection moulding form.Profile and the large I of this nut are determined as required, preferably can diversified, standardization.
The present invention has following major advantage: (1) strong adaptability, be applicable to be in for a long time vibration, impact so Exposure to Sunlight, the rugged environment that drench with rain, can be applicable to engineering machinery, railway locomotive, harbour machinery, bridge works, textile manufacturing machine etc.; (2) structure simple, easy to use, also the geometric form groove of different depth and shape can be selected to match according to the needs of joined spring washer; (3) material is easy to get, and technique is simple, and cost is low, can standardization, can exchange, general; (4) can mate with spring washer preferably and use, shock resistance, anti-vibration satisfactory for result, separation of scattering after spring washer brisement can be prevented, to come off, can stop because the brisement body on spring washer is separated with threaded fastener the caused accident that comes off.
