Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of bearing outer corner measurement frock, use axle through Spherical Ring, and side is provided with the pad be fixed on axle on axle, side is provided with dismountable pad and nut, again weight is filled on axle by suspension ring again, solve that the measuring error caused owing to utilizing axle and spring balance to measure Spherical Ring corner manual measurement in prior art is large, measuring state is unstable, can not ensure the technical matters that product quality is completely controlled.
To achieve these goals, the technical solution used in the present invention is: a kind of bearing outer corner measurement frock, include the main landing gear connecting support arm installation component be assembled by race ring and Spherical Ring, it is characterized in that: axle is through the intermediate throughholes of Spherical Ring, axle is connected with discoidal pad I, described pad I and the joint, side of Spherical Ring, overlap successively at the opposite side of axle and have pad II and nut, pad II can move on axle, fastening nut makes pad II contact with the another side of Spherical Ring, and be clamped between Spherical Ring and nut, the end being provided with nut side at axle also hangs with weight by suspension ring.
Described pad I and axle are that integral type is connected.
Described nut and axle are for being threaded, and axle and nut, axle and pad II are for removably connecting.
A using method for bearing outer corner measurement frock, the steps include:
1), railway grease is coated on the surface of race ring and Spherical Ring;
2), Spherical Ring is assembled as in race ring;
3), the railway grease overflowed is removed;
4) smart of Spherical Ring, is checked:
4a), side is penetrated in Spherical Ring with the axle of pad I;
4b), by pad II through on axle, and fit with the end face of Spherical Ring;
4c), by nut be screwed on axle, and fit with pad II, race ring is fixed on vice, is ajusted on horizontal level by axle, then weight is suspended to the groove of axle by suspension ring, observes the anglec of rotation measuring Spherical Ring.
The beneficial effect of the invention is: the invention provides a kind of bearing outer corner measurement frock, use axle through Spherical Ring, and side is provided with the pad be fixed on axle on axle, side is provided with dismountable pad and nut, again weight is filled on axle by suspension ring again, the invention is by said structure and method, not only increase the quality of assembling, and provide foundation for similar bearing, this fixture brings facility to detection, not only ensure that the quality of part, improve efficiency of assembling, and make installation specification, solve in prior art because the measuring error utilizing axle and spring balance to measure Spherical Ring corner manual measurement and cause is large, measuring state is unstable, the technical matters that product quality is completely controlled can not be ensured.

Embodiment
A kind of bearing outer corner measurement frock, include the main landing gear connecting support arm installation component be assembled by race ring 6 and Spherical Ring 7, it is characterized in that: axle 1 is through the intermediate throughholes 8 of Spherical Ring 7, axle 1 is connected with discoidal pad I2, described pad I2 and the joint, side of Spherical Ring 7, overlap successively at the opposite side of axle 2 and have pad II2-1 and nut 3, pad II2-1 can move on axle 1, fastening nut 3 makes pad II2-1 contact with the another side of Spherical Ring 7, and be clamped between Spherical Ring 7 and nut 3, the end being provided with nut 3 side at axle 1 also hangs with weight 5 by suspension ring 4.
2, a kind of bearing outer corner measurement frock according to claim 1, is characterized in that: described pad I2 with axle 1 for integral type is connected.
Described nut 3 and axle 1 are for being threaded, and axle 1 and nut 3, axle 1 and pad II2-1 are for removably connecting.
A using method for bearing outer corner measurement frock, the steps include:
1), railway grease is coated on the surface of race ring 6 and Spherical Ring 7;
2), Spherical Ring 7 is assembled as in race ring 6;
3), the railway grease overflowed is removed;
4) smart of Spherical Ring 7, is checked:
