Description
Technical field
The utility model belongs to technical field of bearings, especially relevant with a kind of bearing axial play frock.
Background technology
At present, detection both at home and abroad to bearing clearance, by design frock, conventional bearings is detected, but some special bearings are still generally adopted and by hand bearing clearance is detected, as automobile hub bearing, comprise outer ring, inner ring, retainer, rolling body and mandrel, mandrel one end is provided with the ring flange be connected as a single entity with it, the other end is provided with flanging, inner ring and outer ring to be set on mandrel and successively between ring flange and flanging, rolling body is installed between described outer ring and inner ring by retainer, inner ring and mandrel are fixed, mandrel two ends are provided with enlarging step end face, during detection, manually pressure is applied to ring flange and outer ring, by the data that dial gauge is surveyed, draw play, but it is low that this method also exists detection efficiency, bearing distribution is uneven, the personal errors such as easy generation is eccentric are larger, add the defect of the labour intensity of testing staff simultaneously, be difficult to the needs adapting to modernization large-scale production.
Utility model content
The purpose of this utility model is intended to the defect that bearing clearance detection efficiency is low, accuracy is not high overcoming existing automobile hub bearing, provides a kind of easy to detect, bearing axial play frock that accuracy rate is high.
For this reason, the utility model is by the following technical solutions: a kind of bearing axial play frock, it is characterized in that, described frock comprises fixation kit, upper casting die, piece under pressure and clock gauge, fixation kit comprises the upper fixed block and lower fixed block that keep at a certain distance away and be oppositely arranged up and down, the upper surface of lower fixed block is provided with axial boss, the bottom of upper fixed block is provided with pilot hole, hub-bearing unit is positioned between described upper fixed block and lower fixed block and the one end with ring flange is positioned at lower end, the enlarging step end face of hub-bearing unit lower end is resisted against described boss top end face, the lower end surface of upper fixed block is pressed against on the inner ring outer face of hub-bearing unit, the flanging of mandrel is made to be embedded in described pilot hole, described upper casting die and piece under pressure are respectively arranged with corresponding axially extending bore, upper casting die and piece under pressure be the corresponding outside being set in fixed piece and lower fixed block respectively, the aperture place of the axially extending bore lower end of upper casting die is provided with step shoulder down, step shoulder correspondence is resisted against bearing outer ring, described piece under pressure has been uniformly distributed circumferentially three and has compressed pin, the ring flange of hub-bearing unit is provided with three detect aperture compressing with described three and sell corresponding, three compress pin and are each passed through three detect aperture and the lower end surface relying on bearing outer ring, the pointer contact of described clock gauge is in the upper surface of described upper casting die.During use, the inner ring of automobile hub bearing and mandrel are fixed by upper fixed block and lower fixed block, first by applying certain pressure to upper casting die, now data measured by clock gauge, then certain pressure is applied to piece under pressure, now, another data measured by clock gauge, are automobile hub bearing end-play by two data are subtracted each other the difference drawn.
The utility model can reach following beneficial effect: detect by carrying out applying certain power to upper casting die and piece under pressure, make casting die and piece under pressure relatively more even to hub-bearing unit force axially, be not easy to produce eccentric equal error, structure is simple, easy to operate, detection efficiency is high.
