Abstract
A torsional pendulum slender rod connecting sleeve with automatic positioning and fastening functions comprises a connecting sleeve, a rotating shaft hole, a pressure regulating screw, a spring, a steel ball and a slender rod hole; wherein a screwed hole is processed along an axial direction of the connecting sleeve between the rotating shaft hole and the slender rod hole of the connecting sleeve; the steel ball, the spring and the pressure regulating screw are put into the screwed hole in order; and a fraction of a spherical surface of the steel ball is protruded inside the slender rod hole. When a moment of inertia of the slender rod is measured, the slender rod is inserted into the slender rod hole, once an intermediate small circular groove of the slender rod reaches the position of the steel ball, the steel ball pops out immediately to embed into the intermediate small circular groove of the slender rod, thus the slender rod can be fixed easily and accurately, in addition, the pressure regulating screw can flexibly adjust the pressure of the steel ball to the slender rod, thus a firm connection of the slender rod can be ensured.
Description
Technical field
The utility model is applied to the carrying apparatus of torsional pendulum moment of inertia appearance.
Background technology
When measuring the moment of inertia of elongate rod with the torsional pendulum moment of inertia measuring instrument, require elongate rod is inserted in the elongate rod hole of adapter sleeve, in the little annular groove in the centre of elongate rod, locate and fastening with trip bolt; Usually should grasp three main points, 1, estimate---little annular groove in the middle of the elongate rod is inserted into the middle part of adapter sleeve; 2, the location---the trip bolt precession is contacted elongate rod gently, spur elongate rod back and forth; There is micro-displacement but can not pull out, explains that trip bolt has inserted in the middle of the elongate rod to have realized the location, 3 in the little annular groove; Fastening---tighten screw, but in being the student of this experiment always the someone can not grasp this three main points as early as possible, in the middle of not being fastened on sometimes in the little annular groove; Make two ends asymmetric, be tightened in sometimes on the monolateral inclined-plane of little annular groove that elongate rod had been become flexible after swing was got up; These all can influence measuring accuracy, guarantee accurately location and firmly being connected of elongate rod, usually will spend the adjustment process of long period.
Summary of the invention
In order to eliminate difficult problems such as inaccurate, fixing tight and adjusting time of elongate rod location is long, the utility model designed a kind of have automatic location and a fastening function rock the elongate rod adapter sleeve.
The elongate rod adapter sleeve that rocks with automatic location and fastening function comprises retaining adapter sleeve, shaft hole, pressure regulating screw, spring, steel ball, thin bar hole; Between the shaft hole of adapter sleeve and thin bar hole along threaded hole of axial processing of adapter sleeve, the steel ball of packing into successively in the threaded hole, a spring and a pressure regulating screw; The sub-fraction sphere of steel ball is charged in the thin bar hole; When measuring the moment of inertia of elongate rod, elongate rod is inserted thin bar hole, as long as the little annular groove one in the centre of elongate rod is to the steel ball position; Steel ball ejects in the little annular groove in the centre that is embedded into elongate rod immediately; So easily fixed elongate rod exactly, pressure regulating screw can the flexible steel ball to the pressure of elongate rod, guarantee the firm connection of elongate rod.
Accurate positioning when the utility model has the advantages that the installation elongate rod is connected firmly, and is easy and simple to handle, guaranteed the measuring accuracy of elongate rod moment of inertia.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 rocks the structural principle and the embodiment synoptic diagram of carrying apparatus for high-accuracy multifunctional.
Among the figure, 1, the screw rod that is in the light, 2, adapter sleeve, 3, shaft hole, 4, screw, 5, spring, 6, steel ball, 7, thin bar hole.
Embodiment
One end of adapter sleeve (2) is processed with shaft hole (3); The diameter of shaft hole (3) and the rotating shaft of torsional pendulum moment of inertia appearance match; The screw rod (1) that is in the light is connected outside the shaft hole (3), the screw rod that is in the light (1) except connecting rotating shaft, the also double simultaneously function of making the bar that is in the light; Thin bar hole (7) is processed in the middle part of adapter sleeve (2); At shaft hole (3) threaded hole of axial processing between the elongate rod hole (7) along adapter sleeve, pressure regulating screw (4), spring (5) and steel ball (6) have been installed successively, the sub-fraction sphere of steel ball (6) is charged in the thin bar hole (7); Pressure regulating screw (4) regulating spring (5) neatly guarantees the firm connection to elongate rod to the pressure of steel ball (6) with this.
Claims (2)
1. the elongate rod adapter sleeve that rocks with automatic location and fastening function comprises retaining adapter sleeve, shaft hole, pressure regulating screw, spring, steel ball, thin bar hole; It is characterized in that between the shaft hole of adapter sleeve and thin bar hole threaded hole of axial processing along adapter sleeve; The steel ball of packing into successively in the threaded hole; Spring and pressure regulating screw, the sub-fraction sphere of steel ball is charged in the thin bar hole.
2. according to claim 1 have automatic location and a fastening function rock the elongate rod adapter sleeve, it is characterized in that pressure regulating screw can the flexible steel ball to the pressure of elongate rod.
