Abstract
The utility model relates to a faster auxiliary device in the field of mechanical engineering and discloses a nut fattener device, which comprises a nut shell; the nut sleeve locks a nut and is fixedly connected with the surrounding of the bolt hole of a fixing plate; the rotating and moving of the nut are limited by the nut sleeve. The nut fastener device solves the problems in the prior art that holes are drilled on a steel plate and a bolt pair is mounted by tapping, which lead the adjustable clearance volume of a mounted workpiece to be small and lead the bolt to not achieve the due tight force. The nut fastener device also solves the defects the thread deformation of the nuts in the nut welding mode of the prior art caused by being heated affect the bolts to be tightened and lower the strength of the nuts.
Description
Technical field
The utility model relates to mechanical engineering fastening piece auxiliary device.
Background technique
In the secondary fastening piece assembling work of existing bolt, two kinds of operating types are arranged.The one, directly take boring, tapping on steel plate, bolt passes pedestal and directly is screwed on the tapped hole.There is defective in the mode of this boring, tapping on steel plate: the intensity of (1) invar plate is generally low than high-strength bolt intensity, so can only adapt to the low level bolt, even use high-strength bolt, does not also reach the due fastening force of bolt; (2) fix because of tapped hole, make that the workpiece adjustable clearance amount after installing is little.The 2nd, adopt nut is welded on steel plate bolt hole corresponding position, bolt passes pedestal, steel plate is screwed on the nut.The defective that adopts the nut mode on the steel plate that is welded on to exist comprises: heat affecting when weld because of nut (1), easily cause the screw thread distortion, and influence bolt and tighten, also can cause the nut strength step-down; (2) fixing stiff because of the nut welding, the workpiece adjustable clearance amount after same feasible the installation is little.
The model utility content
Technical problem to be solved in the utility model provides a kind of nut fastener device, and it has high-intensity fastening force, has the adjustable characteristics of assemblage gap simultaneously.
For solving the problems of the technologies described above, a kind of nut fastener device that the utility model provides is characterized in that: comprise nut sleeve, described nut sleeve fastens nut, is fixedly connected on the bolt hole periphery of mounting plate, and the rotation of nut reaches to move and limited by nut sleeve.
As the preferred construction design proposal, described nut fastener device also comprises centering ring, and described centering ring is circular, is fixedly connected on the bolt hole periphery of mounting plate, the centering ring ring heart described bolt hole heart that aligns.Described centering ring provides benchmark for the installing and locating of described nut sleeve.
Advantage of the present utility model is: by nut is alignd with bolt hole, nut is installed in it is horizontally rotated in the restricted nut sleeve, utilize nut sleeve and assemble fixedlying connected of object, make nut translation within the specific limits, but can not rotate, after workpiece is installed, the position-adjustable amount is big, solved in the prior art nut directly has been fixed on the assembling object, or boring, tapping on steel plate, make that the workpiece adjustable clearance amount after installing is little, bolt does not reach the problem that fastening force should be arranged; Also solved simultaneously when the assembling object is steel structure, nut has been welded on the steel structure, be influenced by heat and cause screw thread to be out of shape, caused the nut strength step-down to influence the problem that bolt is tightened for preventing that nut from rotating.The utility model is simple in structure, easy for installation, cost is low, simple to operate, using effect good.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 adopts the structural representation of nut welding manner construction bolt pair for prior art.
Fig. 2 adopts the structural representation of steel plate boring or tapping mode construction bolt pair for prior art.
Fig. 3 is a longitudinal construction sectional view of the present utility model.
Lateral structure sectional view when Fig. 4 is cubic type for the utility model embodiment 1 nut sleeve.
Lateral structure sectional view when Fig. 5 is six squares for the utility model embodiment 2 nut sleeve.
Embodiment
Structural representation when nut is welded in steel plate bolt hole corresponding position in the prior art as shown in Figure 1 as seen, fit of the prior art is for to be welded in nut on the mounting plate steel plate 9, bolt 6 is passed pad 7, base plate 8, mounting plate steel plate 9 backs and nut 3 to be fastenedly connected, this method is because nut 3 is stiff, and when welding, be influenced by heat, easily cause the screw thread distortion, influence bolt 6 and tighten, also can cause nut 3 intensity step-downs.
Contrast Fig. 1, boring on the prior art light plate shown in Figure 2, the structural representation during tapping, utilize the mode of boring, tapping on the steel plate to make tapped hole fix, cause workpiece adjustable clearance amount little, and because the intensity of steel plate is generally low than high-strength bolt intensity, so can only adapt to the low level bolt,, also not reach the due fastening force of bolt even use high-strength bolt.
Figure 3 shows that longitudinal construction sectional view of the present utility model, circular centering ring 1 is fixedly connected on bolt hole 11 peripheries of bolt mounting plate 9, is the location positioning of nut sleeve 2.Nut sleeve 2 fastens nut 3 and nut shim 4, is welded on the bolt hole periphery of mounting plate 9, and nut 3 alignment bolts hole 11, the upper end of nut sleeve 2 has bolt exit orifice 5, makes nut 3 not move up and down, but does not influence passing of bolt.
Lateral structure sectional view when the utility model embodiment 1 nut sleeve as shown in Figure 4 is cubic type, it illustrates centering ring 1, nut sleeve 2, nut 3, nut shim 4 mutual horizontal positions, discloses the rotation of nut 3 and move horizontally how to be subjected to nut sleeve 2 restrictions.From cross section, cover six-sided nut 3 in the square nut sleeve 2, six-sided nut 3 underlay round nut pads 4, centering ring 1 is installed in the outer ring of nut shim 4.Greater than the height of six-sided nut 3 and less than nut 3 circle external diameters, this design makes nut 3 be subjected to nut sleeve 2 restrictions when horizontally rotating to the inner width of square nut sleeve 2, and has certain adjusting space slightly.
Have any different slightly with Fig. 4, when the utility model embodiment 2 nut sleeve 2 shown in Figure 5 are six squares, six side's internal diameters of six square nut sleeve 2 make nut 3 be subjected to nut sleeve 2 restrictions equally when horizontally rotating, and have certain adjusting space slightly greater than six side's external diameters of six-sided nut 3.Other structure is identical with Fig. 4, so repeat no more.
The structure of nut sleeve is not limited to above-mentioned, can also optionally be processed into other form, as long as its internal structure is processed into and has at least two parallel surfaces, the beeline of this parallel surface is less than the cornerwise distance of nut section.Limited getting final product when being able to cause nut to rotate, those skilled in the art can understand fully, so do not enumerate one by one.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
