Description
Technical field
The present invention relates to a kind of locking bindiny mechanism, be specifically related to a kind of expansive force locking bindiny mechanism be connected with axle sleeve for vertical stone crusher pressure arm.
Background technique
At present, mine, the applying working condition of disintegrating apparatus is very severe, heavy duty is born as vertical stone crusher etc. belongs to, the equipment of large impact power, and the critical piece such as pressure arm and axle sleeve is large-scale steel-casting, the weight of himself is just very large, very large shearing and impact force is produced between each parts in working procedure, in existing stone crusher structure, general cylindrical pin is all adopted to connect between pressure arm and axle sleeve and locking, coupling mechanism force under initial assembling condition depends on intrinsic value of interference fit, extremely frequently impact and shearing force effect under, be easy between pressure arm and axle sleeve occur to loosen, fitting surface between general cylindrical pin and hole engenders gap, but the outside dimension of this common pin is nonadjustable, whole locking mechanism cannot compensate behind formation gap, locking effect is caused not reach intrinsic perfect condition, vibrate also increasing, gap is increasing, form vicious circle, badly influence the Whole Equipment life-span.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of expansive force locking bindiny mechanism that can lock stably in a long term under severe work shape, to ensure the stability that vertical stone crusher pressure arm is connected with axle sleeve, extension device whole service life.
For achieving the above object, the technical solution used in the present invention is:
A kind of expansive force locking bindiny mechanism, for the connection of vertical stone crusher pressure arm and axle sleeve, described locking bindiny mechanism comprises the consistent tapered sleeve of adpting flange and size fit, tapering and taper pin, the installation inner hole of tapered sleeve outer surface and pressure arm and axle sleeve, be fixedly connected with taper pin by kingbolt in the middle part of adpting flange, edge section is fixedly connected with pressure arm body by secondary bolt, tapered sleeve side offers a through expansive force adjustment tank in the axial direction, and the initial interior fit on taper-face contact area of tapered sleeve and taper pin assembling is no less than 75%.
As the further restriction of the technical program, described expansive force adjustment tank is consistent with tapered sleeve tapering.
Preferably, the initial interior fit on taper-face contact area of tapered sleeve and taper pin assembling is 80%.
As the further restriction of the technical program, described in be fixedly connected with flange and taper pin kingbolt at least arrange one.
Preferably, above-mentioned kingbolt is set to 1, both is fixed with the mounting hole in taper pin by being screwed in by kingbolt on adpting flange.
Preferably, above-mentioned kingbolt circumference in the middle part of adpting flange is evenly provided with 4, is applicable to the fixed installation of larger-size taper and adpting flange.
As the further restriction of the technical program, described adpting flange is adopted as circular flange or square flange.
Expansive force locking bindiny mechanism of the present invention, utilizes the structural feature that inside and outside cone match can be expanded, taper pin, tapered sleeve is made into expansion set structure, form the locking body parts of adjustable expansive force.The conical surface of taper pin, tapered sleeve is after accurate lapping-in, and its area of contact that cooperatively interacts is large, and carrying evenly.When after use a period of time, taper pin evenly can be compressed in tapered sleeve, to expand the outside diameter size of tapered sleeve, continue to keep the outer round surface of tapered sleeve and the inner hole surface of pressure arm and axle sleeve to closely cooperate, eliminate gap, avoid the generation vibrated.
Beneficial effect of the present invention is according to known to describing of such scheme:
The expansive force locking bindiny mechanism of said structure can provide powerful coupling mechanism force, high-impact and shearing force frequently can be born, dismounting is convenient with adjustment, can ensure to realize close contact state between connected compcnent, timely elimination vibration, reduce rate of fault and the maintenance cost of vertical stone crusher, extension device whole service life.

Be labeled as in figure: 1, pressure arm body; 2, tapered sleeve; 3, taper pin; 4, adpting flange; 5, kingbolt; 6, secondary bolt; 7, axle sleeve; 8, expansive force adjustment tank.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
As shown in drawings, the expansive force locking bindiny mechanism that the present embodiment provides, be applied to the connection of vertical stone crusher pressure arm and axle sleeve 7, described locking mechanism comprises adpting flange 4 and size fit, the tapered sleeve 2 that tapering is consistent and taper pin 3, the installation inner hole of tapered sleeve 2 outer surface and pressure arm and axle sleeve 7, be fixedly connected with taper pin 3 by kingbolt 5 in the middle part of adpting flange 4, edge section is fixedly connected with pressure arm body 1 by secondary bolt 6, tapered sleeve 2 side offers a through expansive force adjustment tank 8 in the axial direction, the initial interior fit on taper-face contact area that tapered sleeve 2 and taper pin 3 assemble is no less than 75%, in the present embodiment, the initial engagement taper-face contact area of tapered sleeve 2 and taper pin 3 is 80%.
In the present embodiment, described expansive force adjustment tank 8 is consistent with tapered sleeve 2 tapering.
In the present embodiment, described kingbolt is set to 1, both is fixed with the mounting hole in taper pin by being screwed in by kingbolt on adpting flange.
In technique scheme, described adpting flange 4 is adopted as circular flange.
During making, open conical sleeve 2 and taper pin 3 select high-quality steel, its mechanical properties strength is improved through quenching with Subsequent tempering, both are in manufacturing process, in ensureing, external taper is consistent, tapered sleeve 2 and taper pin 3 match and make complete and after checking taper-face contact area qualified, can carry out slot treatment to open conical sleeve 2; Adpting flange 4 adopts 45 steel steel plates to make, and bolt is all adopted as standard fasteners.
During use, first tapered sleeve 2 is loaded in the endoporus of pressure arm and axle sleeve 7, after taper pin 3 and flange kingbolt 5 connect into an entirety, taper pin 3 is loaded in tapered sleeve 2; Because adpting flange 4 is connected with body, by adjusting the axis amount of compressing into of adpting flange 4, can drive and adjust the degree of depth that taper pin 3 is pressed into tapered sleeve 2, and then tapered sleeve 2 is expanded in diametric(al), reach the effect with the tight blind-mate of bore area of pressure arm and axle sleeve 7, complete and connect the reliable locking of pressure arm and axle sleeve 7, the size of open conical sleeve 2 swelling strength, can realize by adjusting secondary bolt 6.Taper pin 3, the tapered sleeve 2 of this linkage structure can bear huge shearing and impact force, not easily loosen, and can adjust locking strength as required at any time, have the advantage that conventional general cylindrical pin connecting mode is incomparable.
In above-described embodiment, better embodiment of the present invention is described, obviously, under inventive concept of the present invention, still can make a lot of change.At this, should illustrate, any change made under inventive concept of the present invention all will fall within the scope of protection of the present invention.
