Description

Torsional shear type bolt auxiliary connection

Technical field

The utility model relates to a kind of torsional shear type bolt auxiliary connection.

Background technique

For torsional shear type bolt auxiliary connection, it screws connection generally needs oiling agent to ensure its normal safe work, and common surperficial phospholeum metallization processes is difficult to stably meet the demands, and generally selects dry lubricant process.And satisfied lubrication effect will be obtained, except carrying out the oiling agent material proportion determining to be suitable for, coating processes is also a key problem in technology; For the Polymers adhesive type dry lubricant had a large capacity and a wide range, what still continue to use at present is traditional method such as suspension spray, dip-coating, roller coating, brushing.The bolt connection pair of the coated process of those methods usually have lubricating film and ground bond insecure, greasy property is poor, lubricating film applies the problems such as uneven.

Model utility content

The technical problems to be solved in the utility model be in order to overcome prior art lubricating film and ground bond insecure, greasy property is poor, lubricating film applies uneven defect, provides the torsional shear type bolt auxiliary connection that the process of a kind of water wax lubrication dry film process obtains.

The utility model solves above-mentioned technical problem by following technical proposals:

A kind of torsional shear type bolt auxiliary connection, it comprises bolt, nut and packing ring; The inner portion of described bolt is provided with a circular flange face; The surface of described torsional shear type bolt auxiliary connection is provided with Aluminum Coating, zinc-aluminium chrome coating, electrogalvanising layer, phosphating coating and lubricant coating successively.The setting in circular flange face can increase bolt head area of contact, dispersive pressure, reduces wearing and tearing.Each surface-treatment coatings index is undertaken by the process engineering of each coating routine, overall coating.

Preferably, the bolt head of described bolt is hexagon.

Preferably, the screw rod end of described bolt is provided with blossom type afterbody, is provided with annular incision between described blossom type afterbody and the screw rod of described bolt.The utility model combines the head of large hex head bolt and the blossom type afterbody of torsional shear type bolt, and solve large hex head bolt construction inconvenience, inefficiency, torsional shear type bolt head contact area is little, and during installation, bolt transfer head such as cannot to fix at the problem.

Preferably, the surface of described nut is provided with groove vertically.

Preferably, the shape of described groove is flat, rectangular.

Preferably, the quantity of described groove is 6.

In the utility model, above-mentioned optimum condition can combination in any on the basis meeting related domain general knowledge, obtains each preferred embodiment of the present utility model.

Positive progressive effect of the present utility model is: the utility model has enough mechanical strengths and good greasy property, elasticity and pliability good, effectively can absorb mechanical vibration and impact and then raising mechanical movement stability and reduce noise, installation, convenient disassembly, working efficiency is high, is easy to long storage periods and transport.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model preferred embodiment.

Embodiment

The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of torsional shear type bolt auxiliary connection, it comprises bolt 1, nut 2 and packing ring 3; The inner portion of described bolt 1 is provided with a circular flange face; The surface of described torsional shear type bolt auxiliary connection is provided with Aluminum Coating, zinc-aluminium chrome coating, electrogalvanising layer, phosphating coating and lubrication dry film coating successively.The bolt head of described bolt 1 is hexagon.The screw rod end of described bolt 1 is provided with quincunx afterbody, is provided with annular incision between described blossom type afterbody and the screw rod of described bolt 1.The surface of described nut 2 is provided with groove vertically.The shape of described groove is flat, rectangular.The quantity of described groove is 6.

The utility model passes through after bolt connection pair surface treatment, effectively can control the friction factor between screw thread and between supporting surface, thus ensure that the dispersion ratio of auxiliary connection torque coefficient and fastener shaft power, when rechecking if any when not reaching required pretightening force, can be twisted again by large hexagon head wrest fixing spanner, thoroughly compensate for respective deficiency, make it can not only be used on railroad bridge, boiler power plant, tall building, himself feature can also be played in the higher fields such as aircraft factory, nuclear power station.

The utility model adopts special electric spanner when constructing, and this electric wrench is furnished with inside and outside two sleeve pipes, and nut turned round by outer sleeve, apply moment of torsion to bolt, inner sleeve oppositely turns round wabbler, and two torque are equal, direction is contrary, twists off, directly reach prestretching force value to afterbody wabbler.Compare large hexagonal auxiliary connection, it is simple to operate, easy construction, and artifical influence factor is less.

------trimming---contracting bar---rut groove---Dacroment process that heat treatment---rolls tooth---that head is shaping that the utility model main manufacturing processes is: fracture.Concrete example is as follows:

1) get lubrication dry film solvent and go mineral substance soft water to allocate by a certain percentage, adding in rustless steel container, stir;

2) surface treatments such as Aluminum Coating, zinc-aluminium chrome coating, electrogalvanising layer, phosphatization are carried out to workpiece, then put into body lotion dipping 5min;

3) by through step 2) workpiece after process puts into centrifuge and does centrifugal treating, and the speed of centrifuge is no more than 400rad/min, is thrown away by unnecessary raffinate, makes solvent evenly be coated on workpiece surface;

4) by through step 3) workpiece after process puts into baking oven and be incubated 20-60min at 50 DEG C ~ 90 DEG C.

In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.

Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection domain of the present utility model.
