Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of cubing that can detect input shaft two ends spherical pore size fast, accurately.
For achieving the above object and other relevant objects, the utility model provides a kind of input shaft two ends spherical pore size checking device, it comprises a base, described base is provided with a location reference block and a support, described positioning datum piece is provided with a through hole, in described through hole, be provided with a measurement column, the upper end of described measurement column forms a spherical portion, the lower end of described measurement column is connected with an elastic mechanism, described spherical portion is stretched out the upper surface of described positioning datum piece, described support is provided with a dial gauge, the middle part of one lever is hinged on described support, one end of described lever is connected with described measurement column, the other end of described lever contacts with the sounding rod of described dial gauge.
Preferably, one end that described lever contacts with the sounding rod of described dial gauge is provided with an arc sections, and described arc sections contacts with the sounding rod of described dial gauge.
Preferably, the lower end of described measurement column is provided with a groove, and described elastic mechanism is a spring, and the upper end of described spring is positioned at described groove, and the lower end of described spring is supported on described base.
Preferably, described positioning datum piece and described support are integrated mechanism.
As mentioned above, input shaft of the present utility model two ends spherical pore size checking device has following beneficial effect: this cubing in use, only the spherical pore at input shaft two ends need be pressed in respectively in the spherical portion of measurement column, then press down measurement column, the end face of input shaft is contacted with the upper surface of positioning datum piece, for the spherical pore of different-diameter, the degree of depth of spherical portion embedding spherical pore can be different, therefore the distance that measurement column moves down also can be different, the distance that measurement column moves down can be by this dial gauge of lever transmission, by reading the reading of dial gauge and carrying out geometric operation, just can draw the size that will detect spherical pore.This cubing is simple in structure, easy to use, can measure fast, accurately the size of input shaft two ends spherical pore, can effectively improve the detection efficiency of input shaft, reduces the labour intensity of quality inspection personnel.

Embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this instructions.
Refer to Fig. 1,2.Notice, appended graphic the illustrated structure of this instructions, ratio, size etc., all contents in order to coordinate instructions to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this instructions, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, without essence, changing under technology contents, when being also considered as the enforceable category of the utility model.
As shown in Figure 2, the utility model provides a kind of input shaft two ends spherical pore size checking device, and this cubing comprises a base 2, is provided with a location reference block 3 and a support 7 on base 2, positioning datum piece 3, support 7 are fixedly connected with base 2, and support 7 can be arranged to integrative-structure with positioning datum piece 3.On positioning datum piece 3, be provided with a through hole 31, be provided with a measurement column 4 in through hole 31, the upper end of measurement column 4 forms a spherical portion 41, and the lower end of measurement column 4 is connected with an elastic mechanism, and measurement column 4 can move up and down freely in through hole 31.As a kind of preferred embodiment, elastic mechanism can directly be selected spring 5, can be provided with a groove in the lower end of measurement column 4 simultaneously, and the upper end of spring 5 is inserted in this groove, and the lower end of spring 5 is supported on base.Under the elastic force effect of spring 5, the spherical portion 41 of measurement column 4 is stretched out the upper surface of positioning datum piece 3.
