Abstract
The utility model relates to a radian detecting device, in particular to an articulated bearing inner ring outer spherical surface sphericity detection device. The articulated bearing inner ring outer spherical surface sphericity detection device is characterized in that two sides of a support are respectively provided with a fixing frame, wherein one of the fixing frames is provided with a torsion spring meter, and the other fixing frame is provided with a sleeve; one end of the sleeve is provided with a fixing supporting point; the contact of the torsion spring meter and the fixing supporting point of the sleeve are arranged at opposite directions; a positioning board is fixedly arranged at the center of the support; the positioning board is provided with a base used for loading an inner ring; and the contact of the torsion spring meter and the fixing supporting point of the sleeve are respectively arranged at two sides of the base. With the articulated bearing inner ring outer spherical surface sphericity detection device of the utility model, not just several points, but the outer spherical surface of the inner ring can be detected continuously. The inner ring is arranged on the base, the outer spherical surface of the inner ring will contact with the contact of the torsion spring meter in a rotation process, and therefore, it only needs to read the maximum value and the minimum value of the torsion spring meter and calculate the difference of the maximum value and the minimum value, such that the qualified rate of a product can be detected. The articulated bearing inner ring outer spherical surface sphericity detection device is advantageous in high efficiency and small detection error.
Description
Technical field
The utility model relates to a kind of radian detecting device, is specially a kind of oscillating bearing inner ring spherical outside surface sphericity pick-up unit.
Background technology
Oscillating bearing is widely used in the industries such as engineering hydraulic jack, forging machine tool, engineering machinery, automation equipment, automobile absorber, water conservancy machinery, the structure of oscillating bearing is simpler than rolling bearing, it is mainly made up of the outer ring of Internal Spherical Surface an inner ring by spherical outside surface and one, can within the scope of certain angle, make banking motion,, still can normally work when larger in bolster and axle housing hole nonconcentricity.Finish the work because the main outer sphere inner ring of oscillating bearing and Internal Spherical Surface outer ring form friction pair, therefore its sphere is very high to the requirement of sphericity.Whole inner ring spherical outside surface is made up of numerous point, and it can only be certain several point that existing measurer detects deviation from spherical form, detects error and also can increase, and causes product percent of pass not high.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of oscillating bearing inner ring spherical outside surface sphericity pick-up unit.
Described oscillating bearing inner ring spherical outside surface sphericity pick-up unit, comprise support, the both sides that it is characterized in that described support arrange respectively fixed mount, torsion spring table is set on one of them fixed mount, on another fixed mount, sleeve is set, sleeve one end arranges fixed pivot, and the contact of torsion spring table and the fixed pivot of sleeve arrange in opposite directions; The center of described support is fixedly installed a location-plate, and the base for placing inner ring is installed on location-plate, and the contact of described torsion spring table and the fixed pivot of sleeve lay respectively at the both sides of base.
Described oscillating bearing inner ring spherical outside surface sphericity pick-up unit, is characterized in that described fixed mount fixes by bolt and support respectively.
Described oscillating bearing inner ring spherical outside surface sphericity pick-up unit, is characterized in that being provided with fine setting screw mandrel in described sleeve, and the fixed pivot of sleeve is arranged on the end of fine setting screw mandrel.
Described oscillating bearing inner ring spherical outside surface sphericity pick-up unit, is characterized in that being also provided with set bolt on described sleeve, and set bolt is spacing to fine setting screw mandrel.
Described oscillating bearing inner ring spherical outside surface sphericity pick-up unit, is characterized in that described base is connected with location-plate by bolt.
The utility model can the whole inner ring spherical outside surface of continuous detecting, instead of only detect certain several point, inner ring is placed on base, in rotary course inner ring spherical outside surface can with the contact of torsion spring table, as long as read the qualification rate that torsion spring table maximal and minmal value calculated difference are detectable product, efficiency is high, detects error little.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-support, 2-fixed mount, 3-location-plate, 4-sleeve, 5-torsion spring table, 6-fixed pivot, 7-finely tunes screw mandrel, 8-set bolt, 9-contact, 10-base.
Embodiment
Below in conjunction with Figure of description, the utility model is described further:
Oscillating bearing inner ring spherical outside surface sphericity pick-up unit, comprise support 1, both sides at support 1 arrange respectively fixed mount 2, fixed mount 2 is fixing by bolt and support 1 respectively, on one of them fixed mount 2, torsion spring table 5 is set, on another fixed mount 2, sleeve 4 is set, sleeve 4 one end arrange fixed pivot 6, and the contact 9 of torsion spring table and the fixed pivot 6 of sleeve arrange in opposite directions; Be fixedly installed a location-plate 3 at the center of support 1, the base 10 for placing inner ring is installed on location-plate 3, base 10 is connected with location-plate 3 by bolt, and the contact 9 of torsion spring table and the fixed pivot 6 of sleeve lay respectively at the both sides of base 10; In the time that inner ring is placed on base 10, the spherical outside surface of inner ring both sides touches with the contact 9 of torsion spring table and the fixed pivot 6 of sleeve respectively, rotary inner ring, the spherical outside surface of inner ring can streak the contact 9 of torsion spring table, can judge that by the difference of calculating torsion spring table maximal value and minimum value whether this inner ring is qualified, convenient and swift.
Torsion spring table 5 and sleeve 4 can be on fixed mount 2 adjusting position, to adapt to the inner ring of different model, for the fixed pivot 6 that facilitates sleeve regulates, in sleeve 4, be provided with fine setting screw mandrel 7, the fixed pivot 6 of sleeve is arranged on the end of fine setting screw mandrel 7, finely tunes by adjusting the position that screw mandrel 7 is fine-tuning fixed pivot 6; On sleeve 4, be also provided with set bolt 8, after position mixes up, the bolt 8 that is locked can be spacing to fine setting screw mandrel 7.
When detection, inner ring is placed on base, in measuring process, gives a little the power of point toward fixed pivot position, guarantee inner ring spherical surface and fixed pivot near, rotate to an angle again, read the difference of torsion spring table maximal value and minimum value, can detect product percent of pass.
