Abstract

The utility model discloses a solid of revolution inertia anchor clamps, including the last clamp ring on upper portion and the lower clamp ring of lower part, to go up clamp ring and constituteed last inner chamber with lower clamp ring, lower clamp ring's inner chamber is inner chamber down. The device simple structure, with low costs, the conduction band card is in last clamp ring upper end, and area of contact is little, and pressure is big, can not taken place relative the rotation with last clamp ring by the article of examining during the rotation, also can not the run -off the straight.

Description

A kind of solid of revolution moment of inertia fixture

Technical field

The utility model relates to a kind of fixture, specifically a kind of solid of revolution moment of inertia fixture.

Background technology

Existing solid of revolution moment of inertia fixture, inside only has a cavity, and the situation that tested product tilt often occurs, and makes troubles for detecting.

Utility model content

The purpose of this utility model is to provide a kind of solid of revolution moment of inertia fixture, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme:

A kind of solid of revolution moment of inertia fixture, comprise the upper clamp ring on top and the lower clamping of bottom, upper clamp ring and lower clamping constitute inner chamber, and the inner chamber of lower clamping is lower inner cavity.

As further program of the utility model: upper inner chamber and lower inner cavity are right cylinder.

Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, and cost is low, and conduction band is stuck in clamp ring upper end, and contact area is little, and pressure is large, and during rotation, tested product can not relatively rotate with upper clamp ring, also can not run-off the straight.

Accompanying drawing explanation

Fig. 1 is the structural representation of solid of revolution moment of inertia fixture.

Fig. 2 is the structural representation that solid of revolution moment of inertia fixture and standard body combine.

Fig. 3 is the structural representation that solid of revolution moment of inertia fixture and tested product combine.

Fig. 4 is the structural representation of tested product in solid of revolution moment of inertia fixture.

Wherein: the upper clamp ring of 1-, 2-lower clamping, the upper inner chamber of 3-, 4-lower inner cavity, 5-standard body, the tested product of 6-, 61-conduction band, 62-top, 63-afterbody.

Embodiment

Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.

Refer to Fig. 1-4, a kind of solid of revolution moment of inertia fixture, comprise the upper clamp ring 1 on top and the lower clamping 2 of bottom, upper clamp ring 1 constitutes inner chamber 3 with lower clamping 2, and the inner chamber of lower clamping 2 is lower inner cavity 4.Upper inner chamber 3 and lower inner cavity 4 are right cylinder.

Principle of work of the present utility model is: the afterbody 63 of tested product 6 below conduction band 61 has a cylindrical section.The structural strength of conduction band 61 is very large, can bear whole gravity of tested product 6.Lower inner cavity 4 is dimensioned slightly smaller than standard body 5 size, make it can hold standard body 5, upper inner chamber 3 size can coordinate with standard body 5, tested product 6 size, axial location can be realized after standard body 5, tested product 6 put into fixture, upper inner chamber 3 degree of depth is greater than tested product 6 afterbody 63 cylindrical portion size, makes its top inner chamber 3 inwall ensure the not run-off the straight of tested product 6.This apparatus structure is simple, and cost is low, and conduction band 61 is stuck in clamp ring 1 upper end, and contact area is little, and pressure is large, and during rotation, tested product 6 can not relatively rotate with upper clamp ring 1, also can not run-off the straight.

Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.

Claims

1. a solid of revolution moment of inertia fixture, is characterized in that, comprise the upper clamp ring on top and the lower clamping of bottom, upper clamp ring and lower clamping constitute inner chamber, and the inner chamber of lower clamping is lower inner cavity.

2. solid of revolution moment of inertia fixture according to claim 1, it is characterized in that, upper inner chamber and lower inner cavity are right cylinder.
