Description
Technical field
The present invention relates to the frock for running in bearings, particularly relate to a kind of for to the bearings mounted bearing assembling tooling of shaft sleeve parts.
Background technology
In industrial processes, usually can run into the situation of running in bearings in Model For The Bush-axle Type Parts.For example, in breaker assembly shop, what just needs were a large amount of installs bearing in axle sleeve.
The assembling of bearing is undertaken by the pure craft of manpower at first, what adopt is that workman uses "painted-face" character in opera along bearing outer ring, to knock the mode of bearing, while adopting in this way running in bearings, owing between "painted-face" character in opera and bearing being local contact, unbalance stress, be easy to occur the situation that bearing tilts, in addition, owing to being by manually knocking, the unavoidable inclined to one side situation of striking that there will be, once this kind of situation occurs, "painted-face" character in opera just can strike on the inner ring of bearing or strike on axle sleeve, if copper strikes on bearing inner race, knock produced power and can after the rolling element of bearing, reach again outer ring, easily cause the distortion of rolling element, affect the normal use of bearing, if "painted-face" character in opera strikes on axle sleeve, can make the respective end surface irregularity of axle sleeve, affect axle sleeve surface quality, moreover employing is knocked bearings mounted mode and sometimes also be there will be workman to knock the situation of hand, easily causes accident, finally, the mode of knocking installation also has a very large defect, when bearing enters darker axle sleeve, cannot directly with "painted-face" character in opera, knock bearing, in such cases, also need to adopt the transmission rod of columniform or sheet to carry out power transmission, and transmission rod is easy to occur the phenomenon of sideslip, sleeve lining is caused to damage, and then affect the quality of fit between bearing and axle sleeve.
Existence in view of the above problems, has occurred in industrial production with hot charge practice and the bearings mounted technology of cold charge.Cold charge is that bearing is put into low temperature environment, for example, bearing is put into low temperature liquid nitrogen, the bearing contraction of catching a cold, then with instrument, take out and put into axle sleeve, along with the rise of temperature, bearing expands, complete with axle sleeve and coordinate, the method is simple, but needs low temperature liquid nitrogen, low temperature liquid nitrogen needs ultralow temperature to preserve, cost is high, and the use of liquid nitrogen simultaneously also exists higher safety requirements, requirement has strict operational procedure, and is equipped with essential protective articles.Hot charge practice is first to axle sleeve heating, and for example, by high temperature spray gun heating axle sleeve, axle sleeve expanded by heating, then puts into bearing, cooling after, axle sleeve shrinks, and completes and the coordinating of bearing, the method also needs high temperature heat source, is also uneconomical, not too safe method.
Although above-mentioned two kinds of methods can reduce the damage to bearing and axle sleeve, improve the installation accuracy of bearing and axle sleeve, but but all existing the defect of high cost, is only also nowadays to have obtained application in some special fields, and it is not extensively promoted.
People are after having summed up the strong point and weak point of hammering method and hot and cold dress method running in bearings, go out again the extrusion of running in bearings, for example, in the Chinese patent that notification number is CN202097708U, disclosed a kind of bearing assembling tooling that need use while utilizing extrusion running in bearings.This frock comprises a base, base has base plate and top board, the upper surface of base plate is formed for the horizontal plane of holding axle sleeve, on top board, be equipped with vertical guide post, the lower end of guide post is equipped with pressing plate, the upside of pressing plate is rotatably equipped with the screw mandrel parallel with guide post, screw mandrel and top board threaded engagement and be equipped with handle in upper end, during use, axle sleeve is positioned on base plate, bearing centering is positioned over to the upper port place of axle sleeve, then by handle turn screw mandrel, just can drives pressing plate to move down, thereby bearing is pressed in axle sleeve.
Above-mentioned frock has solved that the efficiency that traditional hammering method running in bearings exists is low to a certain extent, low precision and the problem of damaging bearing or axle sleeve, but, owing to being subject to the impact of the initial placement location etc. of axle sleeve and bearing, be easy to occur that bearing collapses the problem flying, once this kind of problem occurs, brings great threat will to workman's personal safety.
Summary of the invention
The object of the present invention is to provide a kind ofly for to the bearings mounted bearing assembling tooling of shaft sleeve parts, to solve the bearings mounted frock of existing employing extrusion, easily collapse the problem that flies bearing.
In order to address the above problem, of the present invention for to the bearings mounted bearing assembling tooling of shaft sleeve parts by the following technical solutions: for to the bearings mounted bearing assembling tooling of shaft sleeve parts, comprise installing rack, lead and upper and lower spaced chopping block and pressing plate, the upside of that is arranged in below in chopping block and pressing plate is provided with for the guide-localization post with axle sleeve and bearing centering cooperation.
The lower end of described guide-localization post is provided with male half coupling structure, and guide-localization post coordinates with axle sleeve centering by its male half coupling structure in use.
One that in described chopping block and pressing plate, is positioned at top is fixedly assemblied on lead, another guiding be assemblied on lead and and installing rack between be provided with telescopic pressing device.
Described pressing device is hydraulic jack.
In described installing rack and chopping block and pressing plate below one between be provided with limited post.
The downside of one that is positioned at top in described chopping block and pressing plate is provided with corresponding with guide-localization post, the bit architecture that allows for guide-localization post is stepped down.
In described chopping block and pressing plate, be positioned at top the downside of be provided with the gland for top last item bearing outer-ring, described in allow bit architecture be formed by the endoporus of gland.
Described gland have two above and all by a station dial, be assemblied on chopping block or pressing plate, guide-localization post and gland are corresponding and also by station dial, be assemblied on chopping block or pressing plate one by one.
Described pressing plate and chopping block are provided with keeper respectively with between corresponding station dial.
Described keeper is alignment pin.
Owing to being arranged in the upside of of below in the chopping block of this bearing assembling tooling and pressing plate, be provided with the guide-localization post for coordinating with axle sleeve and bearing centering, therefore, when in use, can to bearing and axle sleeve, feel relieved by described guide-localization post, thereby guarantee on the one hand the centering between bearing and axle sleeve, also can prevent on the other hand bearing or axle sleeve radial deflection, and then can solve the bearings mounted frock of existing employing extrusion and easily collapse the problem that flies bearing.
