Description
Technical field
The utility model relates to split type axle location locknut, relates in particular to a kind of split type axle location locknut for connecting welding equipment water pipe.
Background technique
Coil feed line is essential equipment in auto manufacturing and steel coiled strip production plant, and axle and axle location locknut are its major parts.At line unwinding equipment, be installed the initial stage, axle location locknut is the parts that are arranged at first in axle.After equipment investment is used, this location locknut occurs that locating stud is loosening, screw thread rust is waited indefinitely after situation about cannot adjust, and need to, by whole equipment complete removal from outside to inside, could process the problem of locating locknut existence, time and effort consuming.
Due to improving constantly of machine building industry automaticity, auto manufacturing and steel coiled strip production plant are all used automaticity to reach more than 90 percent automatic line, and the drawback of automatic line is that place's fault just likely causes the stopping production of whole factory.So the time of processing each fault just seems extremely important, when especially center roller location locknut keeps in repair, therefore how making locating locknut is convenient to installation and removal, is technician's urgent problem.
Summary of the invention
The purpose of this utility model is exactly in order to solve above-mentioned problems of the prior art, a kind of split type axle location locknut is provided, it is simple in structure, easy to use, can freely be adjusted at the position location in axle, while breaking down, can from axle, disassemble fast, save engineering time, save manpower.
For realizing above-mentioned purpose of the present utility model, of the present utility modelly for the split type axle positioning lock main bag that coil feed line axle is positioned, draw together: the first half-nut being oppositely arranged and the second half-nut; By the first half-nut and the docking of the second half-nut, be a plurality of links of complete nut; Wherein, on described the first half-nut and/or the second half-nut, offer the first tapped hole, in the first tapped hole, be provided with for described complete nut is positioned to the jackscrew in described axle.
Wherein, described link is screw or bolt.
Wherein, described the first half-nut and the second half-nut include: the half-nut body of semicircle annular; Be opened in a plurality of tapped holes on half-nut body, itself and described link match.
Preferably, the outer round surface of described half-nut body offers platform, and described tapped hole is vertically opened in described platform.
Particularly, described platform is opened in the one or both sides of described half-nut body outer round surface.
Wherein, described platform is by an outer round surface excision part for described half-nut body is formed.
Or, described platform by the outer round surface along described half-nut body stretch out a part formed.
Compared with prior art, split type axle of the present utility model location locknut has following advantage: axle of the present utility model location locknut is formed the first half-nut being oppositely arranged and the docking of the second half-nut by link, it is simple in structure, easy to use, can freely be adjusted at the position location in axle, while breaking down, can from axle, disassemble fast, save engineering time, save manpower, enhance productivity.
Below in conjunction with accompanying drawing, the utility model is elaborated.

Embodiment
As shown in Figure 1, Figure 3, be the structural representation of split type axle of the present utility model location locknut, wherein, location locknut is for positioning coil feed line axle 4, and it is arranged on the most inboard (as shown in Figure 5) of axle 4.It comprises: two half-nuts that are oppositely arranged, i.e. the first half-nut 1 and the second half-nut 2; By the first half-nut 1 and the second half-nut 2 docking, be a plurality of links 3 of complete nut; Wherein, on the first half-nut 1 and/or the second half-nut 2, offer in the first tapped hole 8, the first tapped holes 8 and be provided with for complete nut being positioned to the jackscrew 9 in axle 4.
Wherein, as shown in Figure 1, link 3 is screw, or as shown in Figure 4, link 3 is bolt.By screw or bolt, the first half-nut 1 and the second half-nut 2 are connected as one, easy to connect, use reliable.
Wherein, as shown in Figure 1, Figure 2, Figure 3 shows, be the first structure of split type axle location locknut, as shown in Figure 1, the first half-nut 1 and the second half-nut 2 have identical structure, comprising: the half-nut body 5 of semicircle annular; Be opened in the second tapped hole 6 on half-nut body 5, itself and link match, thereby make link pass the second tapped hole, two half-nuts are connected as one.
In addition, for the ease of installing, the outer round surface of half-nut body 5 can be offered platform 7, and the second tapped hole 6 is vertically opened on platform 7, and platform 7 can be opened in a side (as shown in Figure 1) or the both sides (as shown in Figure 4) of half-nut body 5 outer round surface.Platform 7 can adopt the outer round surface of half-nut body 5 mode of milling to excise a part and form (as shown in Figure 1), and the part that also can stretch out at the outer round surface of half-nut body 5 forms (as shown in Figure 4).
Adding man-hour, can first make a complete nut positioning for center roller (being processed with the first above-mentioned tapped hole 8), then this nut is divided equally into two half-nuts, the incision of one or two in two half-nuts mills out platform, and processes the second tapped hole 6.
When mounted, two half-nuts are buckled in respectively on the adjustment screw thread of coil feed line axle 7, by bolt or screw, two half-nuts are connected as one, freely adjust behind the position location of center roller, adopt jackscrew that position is fixed, thereby give the expansion of axle and shrink location, making the Swelling and contraction size of axle reach technological requirement.
When adopting integral type axle location locknut, as shown in Figure 5, if axle location locknut 1 ' breaks down, when it is keeped in repair, need to will lean against after four dunnages 6 ', sliding sleeve 3 ', wedge 2 ', oil cylinder 5 ' and the outside fix locknut 4 ' complete removal of axle 4 outsides, could keep in repair by center roller location locknut, the engineering time of cost is more than 10 hours, and waste of manpower.Adopt split type axle of the present utility model location locknut, when it breaks down need to remove time, do not need to remove other component, can directly jackscrew be taken off, again the screw or the bolt that connect two half-nuts are taken off, then just two half-nuts can be taken off, thereby it is repaired or replaced.Therefore, when split type axle location locknut breaks down, it was keeped in repair to the time used in 1 hour, saved greatly manpower and time, improved manufacturing efficiency.
Although above the utility model is explained in detail; but the utility model is not limited to this; those skilled in the art can modify according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
