Description
Technical field:
the utility model relates to a kind of split-type structural angular displacement sensor that can Fast Installation, is specifically related to a kind of constructional device of displacement transducer.
Background technology:
at present, grating, time the angular displacement sensor such as grid version mainly contain two kinds, i.e. monoblock type and split type.Monoblock type has built-in bearing axle system, and structure is more complicated, but uses installation simple and convenient, is common in the angular displacement sensor of larger specification.Split type without built-in bearing axle system, simple in structure, but use to install, adjust complexity, be suitable for the small-sized angular displacement sensor of limited space.Therefore, realize simple in structurely, small-sized Split type angle displacement transducer that again can Fast Installation is more difficult.Integrate, conventional angular displacement transducer mainly contains following some deficiency: one, during split type installation, need to adjust, and the set-up time is relatively long, installs and uses inconvenience; Its two, split type installation accuracy is unstable, is unfavorable for that the precision of angular displacement sensor keeps; Its three, traditional Integral corner displacement sensor structure is complicated, size integral body is larger, is unsuitable for application scenario, little space.Above-mentioned problem is that angular displacement sensor uses the insoluble problem in installing area always.
Utility model content:
the purpose of this utility model is to provide a kind of split-type structural angular displacement sensor that can Fast Installation, and a kind of constructional device of displacement transducer is specifically provided.
above-mentioned object realizes by following technical scheme:
a kind of split-type structural angular displacement sensor that can Fast Installation, its composition comprises: main body, stator, hollow rotor shafts, web joint, described main body is connected with described hollow rotor shafts, described main body and described hollow rotor shafts are fixed by described web joint, described stator is installed in the groove between described main body and described hollow rotor shafts, described main body lower end is fixed by screw and described positioning disk, the short external cylindrical surface D of the inner cylinder face B of described main body and described hollow rotor shafts has minimum tolerance clearance, the plane of orientation A of described main body is connected with the plane of orientation C of described hollow rotor shafts, described main body is connected with the motionless main body of described positioning disk and unit under test, described hollow rotor shafts endoporus and the revolving shaft clearance fit of unit under test are installed, the revolving shaft of unit under test has axial location installed surface E, the revolving shaft upper end of unit under test is provided with ring nut.
described split-type structural angular displacement sensor that can Fast Installation, described short external cylindrical surface D upper end and plane of orientation A deduct the height of short external cylindrical surface D apart from the distance that equals plane of orientation C and plane of orientation A, described short external cylindrical surface D upper end and plane of orientation A distance are not less than zero.
described split-type structural angular displacement sensor that can Fast Installation, described web joint and described main body are fixed by web joint gib screw, and described web joint and described hollow rotor shafts are fixed by hollow rotor shafts gib screw.
described split-type structural angular displacement sensor that can Fast Installation, described stator and described main body are fixed by stator gib screw.
the beneficial effects of the utility model:
1, the utility model is in installation process, first, that the revolving shaft clearance fit of the endoporus of described hollow rotor shafts and unit under test is installed together, the cooperation that described positioning disk is arranged on to the motionless main body of unit under test is installed in seam, then with screw, described main body is fixed in the motionless main body of unit under test by described positioning disk, allows the axial location installed surface E of the described lower surface of hollow rotor shafts and the revolving shaft of unit under test produce distance;
secondly, back out on described web joint the gib screw with described main body and described hollow rotor shafts, unload described web joint;
again, the described hollow rotor shafts that moves axially along the revolving shaft of unit under test, make its lower surface touch the axial location installed surface E of the revolving shaft of unit under test, then the axial location installed surface E of revolving shaft that with ring nut, described hollow rotor shafts is pressed on to unit under test is upper, realized the use Fast Installation process of split-type structural angular displacement sensor that can Fast Installation.Fast Installation method needs while having solved traditional split type installation to adjust, and the set-up time is longer, installs and uses inconvenient problem.
2, the relatively described stator of hollow rotor shafts described in the utility model moves axially certain distance and axially and is radially all being in the required relative position of normal work, and the plane of orientation C of described hollow rotor shafts and short external cylindrical surface D upper end be the height that distance that short external cylindrical surface D upper end and plane of orientation A distance equal plane of orientation C and plane of orientation A deducts short external cylindrical surface D from the structural relation of the distance of the installation plane of orientation A of described main body, short external cylindrical surface D upper end is zero apart from being not less than with plane of orientation A; Described hollow rotor shafts and described main body depart from completely, and the stator that described hollow rotor shafts can be relatively described under the drive of the revolving shaft of unit under test is done gyration, and angular displacement sensor is normal operating conditions.Solve installation accuracy low, be unfavorable for the problem that angular displacement sensor precision keeps.
3, size of the present utility model and distance are all according to the relation constraint that plane of orientation A, inner cylinder face B, plane of orientation C, short external cylindrical surface D are installed, can reduce size and the complexity of physical construction, solved traditional angular displacement sensor structure complicated, overall dimensions is large, is not suitable for the problem that little installing space is used.
